Description

BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a valve module for fluidic connector strips with in each case a base plate, wherein parallel fluidic connector channels are running in the base plate, and wherein the base plate is furthermore immediately connectable to a main valve communicating with the connector channels, and with at least a precontrol pilot valve disposed on the main valve, and wherein the precontrol pilot valve controls the movement of the valve member of the main valve based on a passage flow through a control channel of the main valve.
2. Brief Description of the Background of the Invention Including Prior Art
It is known to provide a valve module for fluidic, i.e. hydraulic or pneumatic, connector strips, including a base plate. Parallel disposed, fluidic connector channels are positioned in the base plate. A fluidic connector strip is a section providing a sequence of connection ports connected to or connectable to fluid connector channels. The base plate can in addition be directly connected to a main valve communicating with the connector channels. At least one precontrol pilot valve is disposed on the main valve. The precontrol pilot valve allows to control the motion of the valve member of the main valve based on a passage flow through a control channel of the main valve. The precontrol pilot valve is formed of an electromagnet valve with electric plug contacts, as described in the German Printed Patent Document DE-Al-4,004,834.
Such directional control valves with a connection layout according to the German Industrial Standard DIN ISO 5599 are furnished with base plates with a field of joining connector channels for pressure lines and for operating lines, for ventilation lines and control lines. The connector channels have to be sealed amongst each other and toward the outside relative to the main valve by a correctly disposed sealing plate. The above mentioned, conventional ISO base plate exhibits a passage of the electrical connector lines through an incorporated cable channel and exhibits a plug contact in the plane of the sealing plate, for a connector socket in a valve or in an intermediate plate. The precontrol pilot valves are screwed onto the narrow side front faces. This construction arrangement is not only sensitive to humidity such that the danger of short circuit arises, but in addition is very expensive and difficult to assemble. The complete valve module has to be demounted and disassembled in case of a short circuit in the intermediate plate in order to reach the connector socket in the intermediate plate and the plug contacts in the base plate. A disadvantageously large assembly and mounting time is required, which can result in a loss of production time and/or a production stoppage in associated production lines, and wherein the kind of the cable feed increases further the risk of a short circuit.
SUMMARY OF THE INVENTION
1. Purposes of the Invention
Is an object of the present invention to provide an electrical connection from the electrical connector lines to the electromagnet valves, from one valve module to a second valve module, and further electrical connections for such valve modules, wherein the electrical connections are protected against humidity and water and are in addition easily assembled and mounted.
It is another object of the present invention to provide a modular system for making electrical and fluid connections, which employ simple modules, where the electrical sections are substantially separated from the fluid sections and where solenoid valves provide a connection between electrical block parts and fluid block parts.

A hollow cable casing 8 is disposed at a narrow side front face 7 of the base plate 1. A plug-in casing 9 is guided telescopically adjustable in the cable casing 8. The plug-in casing 9 forms an angle cover structure 10. The angle cover structure 10 includes an electrical connector socket 11 for the plug contacts 6 of the electromagnet 12 in the precontrol pilot valve 4, as well as an electrical contact transition structure 49 to the plug-in casing 9.
The angle piece plate 10 of the telescopically adjustable plug-in casing 9 can include integrated electrical connector sockets 11, disposed side by side at a distance from each other, for several groups of plug contacts 6 of several electromagnets 12 in several precontrol pilot valves 4.
The electrical cables 13 and plate terminals, respectively, can be cast in an insulating material 14 or, respectively, are welded by ultrasound in an insulated material 14 in the angle cover structure 10 including the telescopically adjustable plug-in casing 9.
The plug-in casing 9 can be stepwise adjusted and locked in the hollow cable casing 8, and in fact in corresponding respective thickness distances 15 of a pressure control plate regulator 16, a throttle plate 17 or, respectively, a pressure blocking plate 18 disposed between the base plate 1 and the main valve 3.
At least one cable storage space 19 can be furnished in the hollow cable casing 8. Excess cable length 20 for an extendible electrical cable 13 can be contained in the cable storage space 19.
Cable casings 8 can be furnished at opposite side faces 21 with an opening 22 in the foot region 23 of the base plate 1 for a free cable feed-through 24. The electrical cables 13, sealed with sealing collars 26, can be fed through a central connector plate 25 adjoining at the first cable casing 8 and at the last cable casing 8, respectively.
A bush 27 for the connection of initiators 28 can be furnished at the angle piece plate 10, with elements 29 displaying the respective switching state ON/OFF, as well as with possibly further display elements for displaying the switching state of the valve. The elements 29, indicating the respective switching state ON/OFF, can be furnished as light emitting diode LED displays 30.
The valve module includes a base plate 1 with several parallel disposed, fluidic connector channels 2 and a main valve 3. The main valves 3 subjected to compressed air or a hydraulic fluid as 5/2-way directional control valve according to the German Industrial Standard DIN ISO 5599. At least one precontrol pilot valve 4 is disposed on the main valve 3. The passage flow through a control channel 5 (FIG. 6) of the base plate 1 and of the main valve 3 allows to control the motion of the valve member of the main valve based on the precontrol pilot valve 4 disposed on the main valve 3. The precontrol pilot valve 4 comprises an electromagnet valve with electric plug contacts 6, which are protected against humidity. The base plate 1 is furnished with a first side 101 on the top of the base plate 1, a narrow-side front face 7, a narrow-side rear face 77, a first connection face 201, and a second connection face 202.
For this purpose, a hollow cable casing 8, made of a suitable plastic material, is disposed at the narrow-side front face 7 of the base plate 1. The cable casing 8 is attached at the base plate 1 by way of a not in detail illustrated, however, a conventional plug connection is employed, for example, of a strip structure or of a strip dovetail structure. Furthermore, a plug-in casing 9 is telescopically adjustably guided in the cable casing 8 and is connected to an angle section structure and/or angle cover structure 10. The angle section structure 10 exhibits an electrical connector socket for the plug contacts 6 of an electromagnet 12 in the precontrol pilot valve 4, as well as an electrical contact transition structure 49 (FIG. 5) for attachment at the plug-in casing 9.
The angle cover structure 10 of the telescopically adjustable plug-in casing 9 is furnished with integrated electrical connector sockets 11, disposed side by side and at a predetermined distance from each other, for a plurality of say, for example, two groups of plug contacts 6 of a plurality of, i.e., in this case two electromagnets 12 in a plurality of respective precontrol pilot valves 4. The electrical cables 13 (FIG. 6), are for example cast into an insulating material 14 at least in the angle cover structure 10 or also including the telescopically adjustable plug-in casing 9. In addition to the blocking of humidity, the plug-in casing 9 together with the angle cover structure 10 is associated with the advantage to balance differing thickness distances 15, for example for main valves 3 of differing thickness as illustrated in FIG. 1, for the additional incorporation of automatic pressure control plate 16, of a throttle plate 17 as shown in FIG. 3, or for a pressure blocking plate 18 as shown in FIG. 2. It is further possible to provide plug-in casings which correspond in their vertical length to a respective vertical length of the automatic pressure control plate 16, of the throttle plate 17, and/or, respectively, of the pressure blocking plate 18.
A cable trough or a cable storage space 19 is formed at least in the hollow cable casing 8 in this construction, wherein excessive length of cable 20, as illustrated in FIG. 6, is contained for an extendible electrical cable 13. The cables cast or otherwise fixed into the plug-in casing can extend outwardly at the lower end of the plug-in casing as desired for being fed into the hollow cable casing 8.
Adjacently adjoining cable casings 8, which are adjoining at opposite side faces 21, as illustrated in FIG. 7, are furnished with an opening 22 in the foot region 23 of the base plate 1 for a free cable passage 24. The electrical cables 13, sealed with sealing collars or sealing sleeves 26 disposed in a wall of a central connector plate and are fed through the central connector plate 25, wherein said central connector plate is adjoining at the last one or a first one of the plurality of cable casings 8.
The display elements 29, displaying the respective switching state ON or OFF, are furnished at a bush 27 for the connection of initiators 28 at the angle cover structure 10 as illustrated in FIG. 4. According to the present embodiment, light emitting diode LED displays 30 serve as such elements display 29. The bush 27 includes several connector pole pairs, as illustrated such as for example connected by conductor pair 36. The bush 27 can, as illustrated, be disposed with a pedestal 31 on the angle cover structure 10 or also be disposed by 90 degrees at the front faces on the side of the angle cover structure 10 as illustrated in FIG. 7.
Such initiators 28 emit measurement signals, which are generated from strokes of a lifting cylinder 33 based on permanent magnets, representing initiators, wherein the permanent magnets are attached at the end of the lifting cylinder 33. A piston 35 associated with permanent magnet is moved from a first position drawn with a solid-line into a second position, drawn with a dashed line, and where the piston 35 actuates there a Reed switch 34 based on a change of the magnetic field, such that an electrical signal is generated, which provides for a control of a directional reverse of the piston 35, wherein the piston 35 now again moves into a respective opposite direction. These signals are fed through the conductor pair 36 to the bush 27.
The angle cover structure 10, as illustrated in FIG. 5, includes a first casing part 37 and a second casing part 38. The two casing parts are connected with a common center piece and further to a press-on face 39, such that the respective connector sockets are slid and shifted into respective plug contacts 6 by applying manual force onto the press-on face 39, wherein advantageously all contacts are closed simultaneously.
The electrical cables 13 are guided through a waterproof cable opening 40 into the plug-in casing 9, as illustrated in FIG. 6. During mounting, the plug-in casing 9 is then plugged and placed into the proper telescope position by way of locking projections 41. A conductor socket 42 passes thereby also into the proper level position. The angle cover structure 10 is screwed there by way of connection screws 45 or, respectively, 32 into a thread 43 of the plug-in casing 9. In addition, a flat gasket 44 capable of sealing, as illustrated in FIG. 7, is inserted between the plug-in casing 9 and the angle cover structure 10 and can be inserted between the hollow cable casing 8 and the plug casing 9.
All electrical cables 13 are guided at a common clamping strip 46 and the in each case desired electrical switching circuits can be created by a multipole plug connection 47 representing polypole coupler. The central connector plate 25 is then closed by a cover 48 for providing easy accessibility of the conductors. The system is thus protected against humidity but is nevertheless extremely flexible with respect to the selection of the necessary device components for a desired valve function of a pneumatic or a hydraulic circuit.
The base plate 1 can be formed so that both the narrow side front face 7 and the narrow side rear face 77 are adapted for receiving a hollow cable casing 8, a plug-in casing 9 and an angle cover structure 10. The main valve is generally disposed at an upper face 101 of the base plate 1.
The electrical contact transition structure 49 and the electrical connector sockets 11 are preferably aligned for providing in both cases connection by performing motion in a parallel direction.
It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of valve modules differing from the types described above.
While the invention has been illustrated and described as embodied in the context of a storage tank for liquefied gases, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
