[0044] Respiratory hole a is equipped on the valve body 1, the respiratory hole a is communicated with the inner cavity of the guide cylinder 101, the sealing plug 3 for plugging the respiratory hole a is equipped on the respiratory hole a.

[0045] It also needs to be explained that in the present application, the respiratory hole a and the corresponding sealing plug are arranged on the valve body 1, so that when the inner wall of the valve body 1 needs to be blown, the valve body 1 can be directly blown from the respiratory hole, quickly solving the medium accumulation problem caused by long time use, reducing the maintenance cost.

[0046] Further, the respiratory hole a is also provided with a sealing sleeve, which is inserted into the respiratory hole a, and a sealing filler is arranged between the sealing sleeve and the respiratory hole a for sealing, such as sealing tape for sealing the gap.

[0047] The inner wall of the sealing sleeve is provided with threads, and the sealing plug 3 is screwed with the sealing sleeve to ensure the sealing effect and prevent the sealing plug 3 from loosening and falling off due to excessive internal pressure of the valve body 1.

[0048] For example, the valve body 1 includes a valve body and an upper valve cover 103, the valve body is provided with a mounting opening, and the upper valve cover 103 is detachably arranged on the valve body, and the breathing hole a is arranged at the center of the upper valve cover 103.

[0049] It should be further pointed out that the purpose of arranging the upper valve cover 103 on the valve body 1 is to directly open the upper valve cover 103 to replace the inside of the valve body 1 when the valve stem 2 needs to be replaced, which is fast and convenient.

[0050] Further, the upper valve cover 103 is fixed on the valve body 1 by bolts, and a lifting ring is further arranged on the end of the bolt for fixing the upper valve cover 103, which is integrally formed with the bolt, so that the valve body 1 can be carried by the lifting ring, and a stress point is provided for the installation of the bolt.

[0051] For example, a compression spring 201 is arranged on the valve stem 2, one end of the compression spring 201 abuts against the upper valve cover 103, and the other end of the compression spring 201 abuts against the valve core.

[0052] It should be further pointed out that the main purpose of arranging the compression spring 201 is to provide a continuous elastic force for the valve core, so that it can be in close contact with the valve seat to ensure the sealing performance of the valve.

[0053] At the same time, the arrangement of the compression spring 201 also helps the smooth movement of the valve core during opening and closing, reduces the shaking of the valve core caused by medium impact or vibration, and improves the stability and service life of the valve.

[0054] For example, the guide support includes a guide ring 4 and a plurality of support rods 5, the support rods 5 are arranged around the guide ring 4, one end of the support rod 5 is arranged on the inner wall of the feed inlet, and the other end of the support rod 5 is arranged on the outer wall of the guide ring 4, and the valve stem 2 is slidingly arranged in the guide ring 4.

[0058] Exemplary, a plurality of second discharge grooves c are arranged on the inner wall of the guide cylinder 101, one end of the second discharge grooves c is connected with the end face of the guide cylinder 101 facing the feed port, and a discharge gap is formed between the second discharge grooves c and the outer wall of the valve stem 2.

[0059] It should be further pointed out that the plurality of second discharge grooves c arranged on the inner wall of the guide cylinder 101 and the discharge gap formed between the second discharge grooves c and the outer wall of the valve stem 2 can significantly increase the discharge area, so that the medium can pass through more smoothly, and by increasing the discharge area, the resistance of the medium when passing through the guide cylinder can be reduced, the flow efficiency of the medium can be improved, the valve can respond faster during opening and closing, the arrangement of the second discharge grooves c helps to optimize the flow state of the medium, reduces the vortex and turbulent flow phenomenon, so that the medium can pass through the guide cylinder more smoothly, reduces the erosion and wear of the valve, and the cooperation of the second discharge grooves c and the discharge gap helps to balance the pressure inside the valve, reduces the problems of valve jamming or damage caused by uneven pressure.

[0064] It should be further pointed out that the purpose of arranging the sealing ring is to further strengthen the strength of the inner wall of the feed inlet, while ensuring the sealing performance when the valve is closed. Meanwhile, the sealing ring is also made of hard alloy, such as cobalt-based hard alloy or tungsten-titanium-cobalt hard alloy, which is used to cooperate with the reinforcing ring 8.

[0065] Exemplarily, the inner wall of the breathing hole a is provided with threads, and the sealing plug 3 is a screw rod, which is screwed with the breathing hole a.

[0066] It should be further pointed out that the inner wall of the breathing hole a is provided with threads, and the sealing plug 3 is a screw rod, which is screwed with the breathing hole a. This design can ensure that the sealing plug 3 tightly blocks the breathing hole a, preventing medium leakage. The threaded cooperation design enables the sealing plug 3 to be firmly retained in the breathing hole a when the internal pressure of the valve body 1 fluctuates, preventing loosening or falling off, thereby ensuring the stability and safety of the valve, and facilitating installation and disassembly.

[0067] Exemplarily, a sealing gasket is arranged between the sealing plug 3 and the valve body 1.

[0070] It should be further pointed out that the sealing gasket is arranged between the sealing plug 3 and the valve body 1, which can effectively fill the small gap between the two, preventing medium leakage through the gap, thereby enhancing the sealing performance of the valve. According to different medium characteristics and working environments, sealing gaskets of different materials and structures can be selected to adapt to different working pressures, temperatures and medium corrosivity, thereby improving the applicability and flexibility of the valve.
