Description

Technical Field

[0001] This utility model relates to the field of high-sensitivity valve cap technology, specifically a high-sensitivity valve cap. Background Technology

[0002] The main function of a valve cap is to prevent media leakage, protect internal parts from external corrosion, and prevent debris and dust from entering the valve, thereby preventing wear and damage to the valve.

[0003] For example, a novel water pump vent valve cap with authorization announcement number "CN203285665U" includes a torsion bar comprising a vertical rod and a horizontal rod. The midpoint of the horizontal rod is integrally connected to the top of the vertical rod, and the lower end of the vertical rod is welded to the center of the top of the valve cap. After the valve cap is put into use, the vent valve can be quickly opened by hand to vent air, which not only restores the water supply pump to normal operation in a timely manner but also prevents water leakage and avoids damage to the vent valve by the wrench. However, during the use of the valve cap, due to its special shape, it needs to be tightened with a clamping tool. After installation, the valve cap is exposed to the outside environment. While it protects the inside of the valve body, it is also affected by the environment. For example, high temperature, low temperature, or corrosive environments can cause the outside of the valve cap to become brittle. This can cause deformation or slippage when the clamping tool is used, making it impossible to disassemble the valve cap properly and reducing the disassembly sensitivity of the valve cap. Utility Model Content

[0004] The purpose of this invention is to solve the problem of valve caps being unable to be properly disassembled, thus reducing the disassembly sensitivity of valve caps, and to propose a valve cap with high sensitivity.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a highly sensitive valve cap, including a cap cover and a through port. The through port is machined on the inner wall of the cap cover. A cap body is fixed to the outer wall of the cap cover. A control structure is connected to the outer wall of the cap body. A padding structure is connected to the front of the cap cover. The outer wall of the padding structure fits against the inner wall of the cap body.

[0007] Preferably, the control structure includes convex plates and grooves, the inner sides of the plurality of convex plates are fixedly connected to the outer wall of the cap body, the outer walls of the plurality of convex plates are respectively machined with grooves, and curved plates are fixedly connected to the outer walls of the plurality of convex plates.

[0008] Preferably, the inner wall of the curved plate is fixedly connected to the outer wall of the cap body.

[0009] Preferably, the padding structure includes a first ring and a straight plate. The rear end face of the first ring is in contact with the front face of the cap. The left and right sides of the inner wall of the first ring are respectively fixed to the outer side of the straight plate. The inner wall of the straight plate is threaded with bolts.

[0010] Preferably, the outer wall of the bolt is threaded to the front circular opening of the cap.

[0011] Preferably, the rear end face of the straight plate is in contact with the front face of the cap, and the outer wall of the first ring is in contact with the inner wall of the cap body.

[0012] The present invention proposes a highly sensitive valve cap, the advantages of which are: by controlling the clamping tool in the structure to be stuck between the protrusions, the clamping tool does not need to clamp the cap body, but only needs to push the protrusions to rotate the valve cap. At the same time, the clamping tool can also be stuck in the groove, and the groove pushes the protrusions to rotate the cap body, ensuring the rotation sensitivity of the valve cap. Meanwhile, the curved plate increases the thickness of the cap body to prevent the cap body from deforming, ensuring the normal disassembly of the valve cap and improving the disassembly sensitivity of the valve cap.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Example 1:

[0020] Please see Figure 1-4 In this embodiment, a highly sensitive valve cap includes a cap 1 and a port 4. The port 4 is machined on the inner wall of the cap 1, and a cap body 5 is fixedly connected to the outer wall of the cap 1. The cap 1 and the cap body 5 constitute a valve cap. A control structure 2 is connected to the outer wall of the cap body 5, and a padding structure 3 is connected to the front of the cap 1. The outer wall of the padding structure 3 is in contact with the inner wall of the cap body 5.

[0021] The control structure 2 includes a convex plate 201 and a groove 202. The inner sides of the multiple convex plates 201 are fixedly connected to the outer wall of the cap body 5. The outer walls of the multiple convex plates 201 are respectively machined with grooves 202. The grooves 202 on the outer and inner walls of the convex plates 201 can be engaged with the clamping tool. The outer walls of the multiple convex plates 201 are fixedly connected with curved plates 203. The inner wall of the curved plates 203 is fixedly connected to the outer wall of the cap body 5.

[0022] The clamping tool in control structure 2 can be locked between the protruding plates 201. At this time, the clamping tool does not need to clamp the cap body. It only needs to push the protruding plate 201 to rotate the valve cap. At the same time, the clamping tool can be locked in the groove 202. The groove 202 pushes the protruding plate 201 to rotate the cap body 5, ensuring the rotation sensitivity of the valve cap. Meanwhile, the curved plate 203 increases the thickness of the cap body 5 to prevent the cap body 5 from deforming, ensuring the normal disassembly of the valve cap and improving the disassembly sensitivity of the valve cap.

[0023] The padding structure 3 includes a first ring 301 and a straight plate 302. The rear end face of the first ring 301 is in contact with the front face of the cap 1. The left and right sides of the inner wall of the first ring 301 are respectively fixed to the outer side of the straight plate 302. The first ring 301 is made of rubber. The inner wall of the straight plate 302 is threaded with a bolt 303. The rear side of the outer wall of the bolt 303 is threaded to the front round opening of the cap 1. The rear end face of the straight plate 302 is in contact with the front face of the cap 1. The bolt 303 plays a role in fixing the straight plate 302 and the cap 1. The outer wall of the first ring 301 is in contact with the inner wall of the cap body 5.

[0024] Working principle:

[0025] Valve cap gasket installation:

[0026] Insert the first ring 301 into the cap body 5 from front to back, so that the rear end face of the first ring 301 is in contact with the front face of the cap 1. At this time, the rear end face of the straight plate 302 is in contact with the front face of the cap 1. Then, the bolt 303 passes through the straight plate 302 from front to back and is connected to the front round hole thread of the cap 1, thus completing the installation of the valve cap gasket.

[0027] Valve cap installation:

[0028] The cap 1 passes through the port 4 from top to bottom through the valve stem, and the cap body 5 connects with the valve body through the inner wall of the internal thread until the first ring 301 is pressed against the top of the valve body. When the rotating valve cap is connected to the valve body, the clamping tool can be stuck between the protrusions 201. At this time, the clamping tool does not need to clamp the cap body. It only needs to push the protrusions 201 to rotate the valve cap. At the same time, the clamping tool can be stuck in the groove 202. The groove 202 pushes the protrusions 201 to rotate the cap body 5, ensuring the rotation sensitivity of the valve cap. At the same time, the curved plate 203 increases the thickness of the cap body 5 to prevent the cap body 5 from deforming.

[0029] Example 2:

[0030] Please see Figure 1-4 In this embodiment, a highly sensitive valve cap further includes a second ring 6, the rear end face of which is fixedly connected to the front face of the cap body 5.

[0031] Working principle:

[0032] After the cap body 5 is installed, the inner wall of the second ring 6 on the front will fit against the outer wall of the valve body, eliminating gaps.

[0033] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
