The present disclosure relates to the technical field of quick valve core removal, and in particular to a quick removal tooling for a valve core.
A valve core is a valve part for enabling a valve body to achieve the basic functions of direction control, pressure control or flow control with the help of its movement. The valve core will be worn and aged after long-term use, and it needs to be replaced in time. However, for valve cores that are faulty or have corroded over time in valve bodies, it may be difficult to remove the valve cores or impossible to complete disassembly during replacement. At present, the method for removing the valve core is mainly to clamp a head of the valve core by pliers, and then take out the valve core by pulling with manpower or tapping with an external force. Not only is it laborious to remove and difficult to control force, but it is also easy to damage the valve body when disassembling in violent situations.
It can be seen that the existing methods for removing valve cores mentioned above have inconveniences and defects, and need to be further improved urgently. How to create a new quick removal tooling for a valve core, which utilizes the lead screw principle and makes the valve core pulled out of a valve body easily through the cooperation of a screw rod and a nut, with a simple and effortless structure, has become a goal that urgently needs improvement in the current industry.
The technical problem to be solved by the present disclosure is to provide a quick removal tooling for a valve core, which utilizes the lead screw principle and makes the valve core pulled out of a valve body easily through the cooperation of a screw rod and a nut, with a simple and effortless structure, thereby overcoming the shortcomings of the existing valve core removing methods.
In order to solve the above technical problem, the present disclosure provides a quick removal tooling for a valve core, including a clamping sleeve, a rotary cap, a nut and a capped screw rod, where a first end portion of the clamping sleeve is provided with a clamping protrusion configured to be clamped with a valve body and an avoidance groove configured to avoid an outer end side of a valve core; a second end portion of the clamping sleeve is in sleeved connection with a first end portion of the rotary cap; the nut is fixed at a central hole of the rotary cap; a screw portion of the capped screw rod extends from a second end portion of the rotary cap, and extends into the clamping sleeve after being in screw thread fit with the nut for achieving matched connection with internal threads of a central hole of the valve core; and after the screw rod is in screwed connection with the valve core, the rotary cap is rotated, which drives rotation of the nut so as to push the screw rod to drive the valve core to be pulled out from the valve body.
For further improvement, the quick removal tooling further includes a rotating handle, where a through hole is reserved in the middle of the rotating handle, the rotary cap is provided with a radial through hole in a side wall close to the second end portion, and the radial through hole is perpendicular to the central hole of the rotary cap; and after the rotating handle passes through the radial through hole, the through hole of the rotating handle is coaxial with the central hole of the rotary cap for the screw rod to pass through.
For further improvement, a counter bored hole is reserved in the second end portion of the rotary cap, and the nut is clamped at the counter bored hole.
For further improvement, the rotating handle is arranged outside the nut to prevent the nut from getting away from the rotary cap.
For further improvement, the quick removal tooling further includes a clamp ring, where a clamping slot is formed in the first end portion of the rotary cap that extends into the second end portion of the clamping sleeve, and the clamp ring is arranged in the clamping slot to prevent the rotary cap from getting away from the clamping sleeve.
For further improvement, the clamp ring is an E-shaped clamp ring.
For further improvement, the clamping sleeve is provided with an observation window in a side wall close to the second end portion, and the observation window is configured to observe whether the valve core is pulled out in place.
For further improvement, a bearing is arranged at a part where the second end portion of the clamping sleeve is in sleeved connection with the first end portion of the rotary cap.
For further improvement, the bearing is a thrust bearing.
For further improvement, the clamping sleeve and the rotary cap are made of a lightweight metal material.
With such a design, the present disclosure has at least the following advantages:
The foregoing descriptions are merely an overview of the technical solutions of the present disclosure. In order to more clearly understand the technical means of the present disclosure, the present disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Exemplary embodiments of the present disclosure will be described in more detail below in conjunction with the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to convey the complete scope of the present disclosure to those skilled in the art.
Referring to
A first end portion of the clamping sleeve 1 is provided with a clamping protrusion 11 configured to be clamped with a valve body 10, and an avoidance groove 12 configured to avoid an outer end side of a valve core 20; and a second end portion of the clamping sleeve 1 is in sleeved connection with a first end portion of the rotary cap 2, so that the rotary cap 2 can rotate relative to the clamping sleeve 1. The nut 3 is fixed at a central hole 21 of the rotary cap 2. The rotary cap 2 is provided with a radial through hole 22 in a side wall close to a second end portion, and the radial through hole is perpendicular to the central hole 21 of the rotary cap. A through hole 51 is reserved in the middle of the rotating handle 5, and the rotating handle 5 is vertically inserted into the rotary cap 2 from the radial through hole 22, so that the through hole 51 of the rotating handle 5 is coaxial with the central hole 21 of the rotary cap 2 for the screw rod 4 to pass through. A screw portion of the capped screw rod 4 extends from the second end portion of the rotary cap 2, passes through the through hole 51 of the rotating handle 5, is matched with the nut 3 by threads, and then extends into the clamping sleeve 1 for achieving matched connection with internal threads of a central hole of the valve core 20.
When in use, after the screw rod 4 is in screwed connection with the valve core 20, the rotating handle 5 is rotated to drive rotation of the rotary cap 2, and the rotary cap 2 drives rotation of the nut 3 so as to push the screw rod 4 to move linearly relative to the rotary cap 2, so that the valve core 20 is ultimately driven to be pulled out of the valve body 10. The removing process is shown in
Specifically, referring to
Preferably, referring to
Specifically, the clamp ring 6 is an E-shaped clamp ring.
In this embodiment, the clamping sleeve 1 is provided with an observation window 13 in a side wall close to the second end portion, and the observation window is configured to observe whether the valve core 20 is pulled out in place. As shown in
More preferably, as shown in
In this embodiment, the clamping sleeve 1 and the rotary cap 2 are made of a lightweight metal material, such as an aluminum alloy material, which is light and easy to operate.
The quick removal tooling for the valve core utilizes the lead screw principle and makes the valve core pulled out of the valve body easily through the cooperation of the screw rod and the nut, and the removing progress can be observed at any time during the disassembly process, so that the entire process is controllable, and the operation is easy and effortless. There is no need for other tools during the disassembly process, which is very efficient and labor-saving, and can also avoid damage to the valve body caused by improper disassembly.
The foregoing descriptions are merely exemplary embodiments of the present disclosure, and are not intended to limit the present disclosure in any form.
