The blocking shell 3 slidably installed inside the pressure relief cover 2 blocks one end of the pressure relief pipe 1. When the output pressure of the pressure relief pipe 1 gradually increases, the blocking shell 3 moves toward the position of the opening of the pressure relief cover 2, and realizes pressure relief when the pressure relief pipe 1 is relatively connected to the small hole. The blocking shell 3 provides the extrusion force for blocking the pressure relief pipe 1 for the blocking shell 3 through the mutual cooperation between the telescopic sleeve 31, the positioning circular plate 32, the arc plate bracket 33 and the adjusting assembly 4 and the pressure relief cover 2;
[0026] like Figure 1 、 Figure 4 and Figure 5As shown, the adjustment assembly 4 includes a spring 41, which is sleeved on the outside of the telescopic sleeve 31, one end of the spring 41 passes through the inside of the pressure relief cover 2, one end of the spring 41 is fixed to the side wall of the blocking shell 3, and the other end of the spring 41 is fixed to the positioning circular plate 32. An adjusting ring 42 is fixed to the center of the spring 41, and the adjusting ring 42 is slidably installed between the outer walls of the telescopic sleeve 31. The spring 41 provides the blocking shell 3 with an elastic force to squeeze the pressure relief pipe 1. The adjusting ring 42 is relatively fixed to the spring 41.

The blocking shell 3 provides the extrusion force for blocking the pressure relief pipe 1 for the blocking shell 3 through the mutual cooperation between the telescopic sleeve 31, the positioning circular plate 32, the arc plate bracket 33 and the adjustment component 4 and the pressure relief cover 2. The elastic force for squeezing the pressure relief pipe 1 is provided to the blocking shell 3 through the spring 41. The adjusting ring 42 is relatively fixed to the spring 41. When When the control adjustment ring 42 moves, the elastic extrusion force between the spring 41 and the sealing shell 3 can be adjusted within the moving range. The adjusting ring 42 is installed on the limit frame 45 through the side plate 43, the limit block 44 and the elastic telescopic rod 47. When it is necessary to adjust the extrusion force of the sealing shell 3, the outward pull handle 48 overcomes the elastic force of the elastic telescopic rod 47. At this time, the limit frame 45 and the limit boss 46 move outward as a whole, and the limit boss 46 is disengaged from the circular groove on the side wall of the arc plate bracket 33. At this time, the relative distance between the adjusting ring 42 and the side wall of the pressure relief cover 2 can be controlled to achieve the purpose of controlling the extrusion force of the sealing shell 3.
