Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve that prevents accidental opening. Background Art

[0002] Valves are mainly used to open and close pipelines, control flow direction, regulate and control pipeline transportation accessories. Valves are control components in fluid transportation systems and have the functions of cutting off, regulating, diverting to prevent backflow, stabilizing pressure, diverting or overflowing and relieving pressure.

[0003] The existing anti-accidental-opening valve fixes the rotating rod with a clamping piece. The valve body can only be rotated by pressing the clamping piece and turning the handle. However, in the process of accidental touch, the clamping piece may also be pressed down, which will also cause the valve body to rotate, thereby causing liquid or gas leakage. Utility Model Content

[0028] Valves are mainly used to open and close pipelines, control flow direction, regulate and control pipeline transportation accessories. Valves are control components in fluid transportation systems and have the functions of cutting off, regulating, diverting to prevent backflow, stabilizing pressure, diverting or overflowing and relieving pressure.

[0029] In the related art, the clamping part may also be pressed down during the process of accidental touch, which will also drive the valve body to rotate, thereby causing liquid or gas leakage.

[0030] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a valve that prevents accidental opening. When the rotating rod needs to be locked, it is only necessary to push up the telescopic rod 22 so that the clamping part 25 is reconnected and fixed, and finally rotate the threaded sleeve 261. The rotating threaded sleeve 261 moves downward and squeezes the top of the support frame 21, thereby limiting and fixing the telescopic rod 22.

[0031] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0032] Combine Figure 1-Figure 3 The embodiment of the present application provides a valve that prevents accidental opening, including a valve body 1; the valve body 1 includes: pipes 12 are provided at both ends of the valve body 11; a flange 13 is provided at one end of the pipe 12; a locking assembly 2 is provided on the outside of the valve body 11, and the locking assembly 2 includes: a support frame 21 is provided on the outside of the valve body 11; a telescopic rod 22 passes through the valve body 11 and the support frame 21; a valve ball 14 is provided at the bottom of the support frame 21 and is located inside the valve body 11; a support plate 23 is symmetrical to the outside of the telescopic rod 22; a clamping piece 25 is provided on the support plate 23; a thread 26 is provided on the outside of the telescopic rod 22, and a threaded sleeve 261 that matches the thread 26 is provided on the outside of the telescopic rod 22 and is located at the top of the support frame 21.

[0033] First, the valve body 1 is installed on the gas pipeline through the flange 13. When in use, the telescopic rod 22 is pressed down to release the clamping piece 25, so that the telescopic rod 22 can be rotated. The rotating telescopic rod 22 drives the valve ball 14 in the valve body 11 to rotate, so that the valve ball 14 blocks and seals the valve body 11. Then, the telescopic rod 22 is pushed up to reconnect and fix the clamping piece 25. Finally, the threaded sleeve 261 is rotated. The rotating threaded sleeve 261 moves downward and squeezes the top of the support frame 21, thereby limiting and fixing the telescopic rod 22 to avoid accidentally touching the telescopic rod 22. The telescopic rod 22 is pressed down to release the clamping piece 25, thereby rotating the telescopic rod 22, causing the valve body to rotate and gas leakage, thereby increasing the safety of the anti-accidental opening valve.

[0034] In some embodiments, a spring 24 is provided between the support plates 23 and is sleeved on the outside of the telescopic rod 22 to support the telescopic rod 22. When the telescopic rod 22 is pressed down, the spring 24 is in a compressed state. When the telescopic rod 22 is released, the spring 24 pushes the telescopic rod 22 to reset due to its resilience.

[0035] In some embodiments, the connecting member 25 includes: a card block 251 symmetrical to the top of the support plate 23, and a card slot 252 is provided on the support frame 21 to match the card block 251, so that the telescopic rod 22 is engaged with the support frame 21 and the rotation of the telescopic rod 22 is locked.

[0036] In some embodiments, a positioning rod 28 is provided on the outside of the support plate 23, and a positioning block 281 is provided on the valve body 11 to cooperate with the positioning rod 28. By aligning the positioning rod 28 with the positioning block 281, it is convenient for the staff to rotate the telescopic rod 22 so that the block 251 can be accurately aligned with the slot 252 for engagement and fixation.

[0037] In some embodiments, an extrusion plate 27 is provided at the bottom of the threaded sleeve 261 and is sleeved on the outside of the telescopic rod 22, increasing the extrusion area of ​​the threaded sleeve 261 on the top of the support frame 21 and increasing the stability of the threaded sleeve 261 in limiting and fixing the telescopic rod 22.

[0038] In some embodiments, an anti-slip layer 271 is provided at the bottom of the extrusion plate 27 and is located on the top of the support frame 21 to increase the anti-slip property of the extrusion plate 27 when extruding the top of the support frame 21 .

[0039] In some embodiments, a sealing gasket 15 is provided between the support plate 23 and the valve body 11 to cooperate with the telescopic rod 22 , thereby increasing the gas sealing performance at the point where the telescopic rod 22 passes through the valve body 11 .

[0040] In some embodiments, a direction indicator 16 is provided on the top of the support frame 21 to facilitate staff to understand the rotation direction of the valve switch.

[0041] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.

[0042] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
