The present invention generally relates to a fluid conveying and/or delivering device provided with an identification label and particularly to a hydraulic valve with a labeling module, for example in fluid conveying and delivering systems.
In order to optimize and economize the production of fluid conveying and delivering systems, for example hydraulic circuits, provided with tubing and valves of various nature, for example control valves, regulating valves, outlet valves, dampening valves, delivery valves or selector valves, the valves are usually produced in large series independently from the tubing and connected to the latter only upon assembling the hydraulic circuit.
In a fluid conveying system with a plurality of valves having various functions, circuits and sub-circuits of tubing and various types of fluids (liquids, gases, cold, hot, corrosive, toxic, food, sterile etc.) it is desired to be capable of identifying the function of a valve, the type of fluid flowing through the valve, the origin thereof, the maintenance or replacement date, the next maintenance or replacement date and other useful information for the prompt understanding of the function and status of each single valve.
When fluid conveying systems are being sold and installed, it may be further desired to provide the valves being provided and used with an identification label of the company selling or installing the latter, for example carrying a trademark.
Known solutions for the labeling of valves of the above-mentioned type provide for example an irreversible identification labeling that is obtained during the moulding step. This type of labeling is expensive and not sufficiently versatile to suit the different types of information which one desires to show on a valve.
A further solution used for the labeling of valves involves the application of adhesive labels, either written by a pen or by means of a printer, on the outer surface of the valve body. While being more versatile and easily adaptable to the various identification requirements and arrangement of information, it nevertheless results to be little resistant to corrosive environments, can be easily manipulated and entails an undesired accumulation of old adhesive labels that are difficult to remove in case a same valve is frequently re-used in various installations and/or functions.
It is further known to hang an identification label either written by hand or by means of a printer on the exterior of a valve, for example by means of a wire. This solution has a high risk of detaching the label, an insufficient resistance to corrosive substances and environments, and is prone to the accumulation of dirt and dust.
Accordingly, the object of the present invention is to provide a fluid conveying and/or delivering device, for example a valve, having at least one labeling module, having such characteristics as to overcome the drawbacks cited with reference to prior art.
A further object of the present invention is to provide a fluid conveying and/or delivering device, for example a valve, with at least one labeling module, having such characteristics as to be easily adapted to various labeling requirements, changes in the intended use and function of the device, while being consistent with a mass production of the device.
Yet another object of the present invention is to provide a fluid conveying and/or delivering device, for example a valve, with at least one labeling module, having such characteristics as to resist to corrosive and aggressive substances and environments.
These and other objects are achieved by means of a fluid conveying and/or delivering device, for example a valve, comprising:
Thereby, the identification label can be easily replaced, is well visible through the transparent window and is protected by the protection lid.
In accordance with an aspect of the present invention, the housing of the device, particularly of a valve, comprises a connecting portion and the protection lid is directly connectable to the housing connecting portion.
In accordance with a further aspect of the present invention, the device, particularly a valve, comprises a control handle and the protection lid can be connected to a suitable connecting portion of the control handle.
In accordance with a further aspect of the present invention, the label seat is made in the protection lid and can be accessed from an inner side which is intended to face the device connecting portion.
In accordance with a still further aspect of the present invention, the label seat comprises at least one positioning edge suitable to engage a corresponding positioning edge of the label, such as to prevent any malpositioning of the label relative to the label seat.
In accordance with a still further aspect of the present invention, the protection lid comprises one or more snap-connecting portions, for example resilient teeth, to snap-engaging the corresponding connecting portion of the device.
In accordance with a still further aspect of the present invention, the protection lid is made of transparent plastics.
In order to better understand the invention and appreciate the advantages thereof, several non-limiting exemplary embodiments thereof will be described below with reference to the annexed drawings, wherein:
With reference to the figures, a fluid conveying and/or delivering device, for example a valve, is generally designated with reference 1. By way of non-limiting example, such a valve can comprise a valve body or housing 2, a shutter 3 arranged within the valve body 2 controlled by the fluid flow through the valve 1 (
In accordance with a general embodiment of the invention, the device 1 comprises a housing 2 with one or more tubular connecting portions 7 that can be removably connected to corresponding connecting portions (not illustrated) of a fluid conveying and/or delivering system, for example a tubing system.
The device 1 further comprises a labeling module 5 with a label seat 6 to accommodate an identification label 8 and a protection lid 9 that can be removably connected to the device 1 such as to close the label seat 6 outwardly of the device 1. The protection lid 9 comprises a transparent window 10 allowing to view the identification label 8 inside the label seat 6 from the outside of the device 1 and protection lid 9.
A valve with a thus-configured labeling module 5 resolves a number of drawbacks of the prior art. Particularly, the identification label 8 can be easily replaced, is well visible through the transparent window and is protected by the protection lid 9.
The identification label 8 can be provided with indicia that can be written by hand, by means of a printer or by means of silkscreen-printing and can have a self-adhesive rear surface for fixing the label to a support plate 11.
In accordance with an embodiment (
Alternatively, the protection lid can be connected to a suitable connecting portion 13 of the control handle 4 of device 1 (
In accordance with a further embodiment, the label seat 6 is formed in the protection lid 9 such that the identification label 8 (with or without the support plate 11) and the protection lid 9 provide a lid-label unit or lid-support-label unit 15 that can be connected to and removed from the device 1 as a pre-assembled unit.
This makes the labeling and re-labeling of the device 1 faster and easier.
Preferably, the label seat 6 made in the protection lid 9 can be accessed from an inner side 17 thereof which is intended to face the connecting portion 12, 13 of the device 1 and can comprise means to hold the identification label 8 and, when provided, the support plate 11, therein, for example one or more holding edges 18.
The label seat 6 can further comprise at least one positioning edge 19 suitable to engage a corresponding positioning portion 20 of the identification label 8 and/or support plate 11 thereof, such as to ensure a correct positioning of the identification label 8 relative to the label seat 6.
Advantageously, the protection lid 9 comprises one or more snap-connecting portions, for example resilient teeth 21, in order to snap-engaging the corresponding connecting portion 12, 13 of the device 1 or vice versa.
Alternatively, the protection lid 9 can be reversibly connectable to the device 1 by means of press-fit, screwing, magnetic attraction, shape-connection or bayonet connection, it may be lockable by means of a lock (not illustrated in the drawings) to prevent any unauthorized handling of the information carried on the identification label 8.
The protection lid 9 is preferably made of transparent plastic material and comprises a substantially planar base wall 22, preferably circular, which forms the transparent window 10, as well as a side wall 23 laterally defining the label seat 6 and forms the connecting portions 21 and the positioning edge 19.
Furthermore, the protection lid 9 and the corresponding connecting portion 12, 13 of valve 1 are preferably configured to insulate or separate the label seat 6 in a substantially air-tight manner from the external environment of the valve, such as to protect the identification label 8 from direct contact to corrosive or aggressive or liquid substances that can drip or be sprayed on the valve outer surface.
In order to avoid the deposit of dirt in the vicinity of the labeling module 5, the protection lid 9 advantageously has an outer surface 24 substantially flush with an adjacent outer surface 25 of the device 1, particularly of the housing 2 or control handle 4.
Obviously, to the device 1 according to the present invention, those skilled in the art, aiming at meeting contingent and specific requirements will be capable of make further modification and variations, which are all contemplated within the scope of protection of the invention, such as defined in the claims below.
