[0033] The pressure regulating mechanism includes a support cylinder 2, which is fixedly connected to the inner side of the valve housing 1. The surface of the support cylinder 2 is fixedly connected with an adjusting cylinder 21. The inner side of the adjusting cylinder 21 is fixedly connected with a support rod 22. The inner side of the adjusting cylinder 21 is connected with an adjusting plate 23. The support rod 22 and the adjusting plate 23 are in abutting connection. The inner side of the support cylinder 2 is fixedly connected with a fixing ring 24. The inner side of the adjusting cylinder 21 is slidably connected with an adjusting ring 25. The adjusting ring 25 and the adjusting plate 23 are fixedly connected. The inner side of the support cylinder 2 is fixedly connected with a support member 26. A pull rope 27 is wound around the surface of the support member 26. The surface of the adjusting plate 23 is fixedly connected with a connecting block 28. The surface of the connecting block 28 is fixedly connected with a support spring 29. The surface of the fixing ring 24 is fixedly connected with a telescopic spring 210. Through the connection between the support cylinder 2 and the adjusting cylinder 21, under the sliding connection between the adjusting plate 23 and the adjusting cylinder 21, and through the action of the support rod 22, the acting angle of the adjusting plate 23 in the adjusting cylinder 21 is changed. Under the connection between the pull rope 27 and the adjusting ring 25, the connection between the adjusting ring 25 and the adjusting plate 23, and the pulling of the pull rope 27, the acting position and acting angle of the adjusting ring 25 and the adjusting plate 23 in the adjusting cylinder 21 are changed, achieving the change of the acting size of the adjusting plate 23 and realizing the adjustment of the transportation pressure.

One part of the support member 26 is in a long rod shape, and the other part of the support member 26 is in a disc shape. The two parts of the support member 26 are rotatably connected. Through the connection between the support member 26 and the support cylinder 2, under the action of the support member 26, the support of the acting position of the pull rope 27 in the support cylinder 2 is realized.

[0036] Further, the pull rope 27 is connected to the surface of the adjusting ring 25. The connecting block 28 is connected to the surface of the adjusting plate 23 in a block shape.

[0038] Furthermore, a support mechanism is provided on the surface of the valve housing 1. The support mechanism includes a fixed chamber 3 fixedly connected to the surface of the valve housing 1. A support plate 31 is slidably connected inside the fixed chamber 3. A snap ring 32 is fixedly connected to the surface of the support plate 31. A threaded hole is formed on the surface of the snap ring 32, and a screw 33 is movably connected inside the threaded hole. A pressing block 34 is movably connected to the surface of the screw 33. Through the connection between the fixed chamber 3 and the valve housing 1, and with the sliding connection between the support plate 31 and the fixed chamber 3, the change in the acting position of the snap ring 32 on the valve housing 1 is realized. Under the connection action of the screw 33 and the pressing block 34, the adjustment of the acting size of the snap ring 32 is realized.

[0039] Furthermore, the support plates 31 are connected in two groups to the surface of the valve housing 1. One group of support plates 31 is slidably connected to the fixed chamber 3, and the other group of support plates 31 is fixed to the surface of the valve housing 1. The support plates 31 are in the shape of long plates. Through the sliding connection between the support plates 31 and the fixed chamber 3, and with the connection between the support plates 31 and the pull rope 27, when the support plates 31 slide in position, the effect of changing the acting length and position of the pull rope 27 inside the valve housing 1 is achieved.

[0040] Furthermore, the snap ring 32 is in the shape of a circular arc. The screws 33 are connected in two groups at both ends of the snap ring 32. The surface of the pressing block 34 is in the shape of a circular arc. Through the connection between the snap ring 32 and the support plate 31, and with the rotational connection between the screw 33 and the snap ring 32, the change in the acting position of the pressing block 34 on the snap ring 32 is realized, achieving the adjustment of the clamping and supporting sizes of the snap ring 32.

[0041] Furthermore, a sealing mechanism is provided on the surface of the valve housing 1. The sealing mechanism includes a pressing ring 4 fixedly connected to the surface of the valve housing 1. A connecting ring 41 is sleeved on the surface of the pull rope 27. A rubber ring 42 is fixedly connected to the surface of the connecting ring 41. An adjusting rod 43 penetrates through the surface of the connecting ring 41. Through the connection between the pressing ring 4 and the valve housing 1, under the action of the pressing ring 4, the support for the position movement of the pull rope 27 on the valve housing 1 is realized.

[0042] Furthermore, the surface of the abutting ring 4 is in an arc shape. The abutting ring 4 is abutted and connected to the pulling rope 27. The surface of the rubber ring 42 is inclined. The adjusting rod 43 is rotationally connected to the valve housing 1 by threads. Through the connection of the connecting ring 41 and the rubber ring 42, under the action of the rubber ring 42, the rubber ring 42 is inserted and connected to the valve housing 1, realizing the connection seal between the pulling rope 27 and the valve housing 1. Under the action of the adjusting rod 43, the effect of fixing and adjusting the acting position of the rubber ring 42 is achieved.

[0043] Working principle: When using the valve housing 1, first, the operator rotates the adjusting rod 43 to separate the rubber ring 42 from the valve housing 1. Then, the operator pulls the support plate 31 to make the support plate 31 slide in the fixed bin 3, driving the position of the clamping ring 32 on the connecting cylinder 13 to change, realizing the support of the connecting pipe on the connecting cylinder 13 by the clamping ring 32. Under the rotational connection of the screw 33 and the abutting block 34, the adjustment of the clamping and supporting dimension of the clamping ring 32 is achieved, so as to support and stabilize the connection and fixation of the pipe.

[0044] When the position of the support plate 31 changes, through the connection of the support plate 31 and the pulling rope 27, the position of the pulling rope 27 in the valve housing 1 changes. The pulling rope 27 is connected to the adjusting ring 25, causing the adjusting ring 25 to drive the adjusting plate 23 to change its position in the adjusting cylinder 21. Under the action of the support rod 22, the change of the acting angle of the adjusting plate 23 in the adjusting cylinder 21 is achieved, realizing the adjustment of the acting dimension of the adjusting plate 23, and further changing the acting pressure in the valve housing 1. Through the connection of the telescopic spring 210 and the fixed ring 24, the elastic sliding between the fixed ring 24 and the adjusting ring 25 is achieved, reaching the self-resetting effect of the acting position and angle of the adjusting plate 23. After the position of the clamping ring 32 is fixed, the operator rotates the adjusting rod 43 in the reverse direction to make the connecting ring 41 push the rubber ring 42 to connect with the valve housing 1, realizing the sealed connection between the pulling rope 27 and the valve housing 1.
