A rocking handle 27 is arranged at the eccentric position of the second gear 26, and the second gear 26 can be conveniently rotated by a worker through the rocking handle 27. In this embodiment, the number of teeth of the second gear 26 is greater than the number of teeth of the first gear 13, and when the second gear 26 rotates for one circle, the first gear 13 necessarily rotates for more than one circle, so that people can drive the first gear 13 by rotating the second gear 26, which is more time-saving and labor-saving.

Referring to fig. 3, the valve cover 14 is a rectangular and vertical plate, the size of the valve cover 14 is matched with that of the opening of the valve body 1, and the valve cover 14 is disposed at the opening and used for closing the opening of the valve body 1. An input port 15 is formed in the middle of the valve cover 14, and the input port 15 is communicated with a pipeline of external high-pressure fluid conveying equipment and used for conveying high-pressure fluid into the valve body 1.

The valve cover 14 is provided with two butt-joint blocks 17 on one side close to the opening, and the two butt-joint blocks 17 are parallel to each other and are perpendicular to each other between the valve cover 14. The valve cover 14 and the butt-joint block 17 are formed by integral punch forming, and in other embodiments, the valve cover 14 and the butt-joint block 17 can be fixed by welding, and other connection modes can be adopted as long as the stability of the connection between the valve cover 14 and the butt-joint block 17 is not affected.

The sections of the second clamping groove 20 and the second clamping block 21 are of sawtooth structures, and the second clamping groove 20 is connected with the second clamping block 21 in a clamping mode. The zigzag structure can increase the connection area between the second clamping groove 20 and the second clamping block 21, so that the butt joint between the butt joint block 17 and the butt joint groove 16 is tighter.

In summary, the working principle of the present embodiment is as follows:

firstly, the butt joint block 17 on the valve cover 14 is inserted into the butt joint groove 16 on the valve body 1, so that the first clamping block 19 and the second clamping block 21 are respectively clamped into the corresponding first clamping groove 18 and the corresponding second clamping groove 20 to complete the installation of the valve cover 14 on the valve body 1, and then the input port 15 on the valve cover 14 is communicated with external high-pressure fluid conveying equipment, so that high-pressure fluid enters the valve body 1. When the pressure in the valve body 1 needs to be adjusted by a worker, the worker only needs to hold the crank rotating gear II 26 by a hand to drive the gear I13 to drive the screw rod 11 to rotate, and the screw rod 11 drives the fixing block 22, the telescopic rod 23 and the valve block 9 to move in the valve body 1, so that the valve block 9 moves horizontally in the chute 4 to adjust the opening size of the output port 2, and the fluid flow rate of the valve body 1 and the pressure borne by the interior of the valve body 1 are quickly changed.

When the pressure in the valve body 1 increases suddenly, the high-pressure fluid in the valve body 1 impacts the bag body 28 of the valve block 9, and is distributed to two sides on the surface of the arc-shaped part of the bag body 28, so that the impact received by the valve block 9 is reduced, meanwhile, the valve block 9 can drive the telescopic rod 23 to contract under the impact action, the buffer spring 24 is compressed, the kinetic energy of the impact of the air flow is converted into the elastic potential energy of the buffer spring 24, and the impact received by the valve block 9 is further reduced. Meanwhile, high-pressure fluid in the valve body 1 enters the flow channel 6 through the through groove 3, so that the pressure relief film 7 expands and breaks, and then the high-pressure fluid in the valve body 1 is discharged along the film opening direction of the pressure relief film 7, so that the pressure in the valve body 1 is reduced, and the valve body 1 is prevented from being damaged.

It is worth mentioning that after the pressure relief membrane 7 is damaged, the continuous use of the pressure relief assembly in the pipeline pressure valve can be maintained only by screwing out the corresponding groove plug 5 from the through groove 3 of the valve body 1 for replacement, so that the maintenance of maintenance personnel is facilitated.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
