Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a pressure regulating butterfly valve, fixed connection's last pipeline 2 on valve body 3 and valve body 3, spout 13 has been seted up in valve body 3, and sliding connection has two slip cushions 4 in

spout

13, 2 internal rotations in the last pipeline are connected with

pivot

12, and 12 bottom fixedly connected with case 6 of pivot, and 12 top fixedly connected with handles 9 of pivot, case 6 and two 4 clearance fit of slip cushions, 9 bottom rotations of handle are connected with bull stick 8, so that it is fixed with draw-in groove 10 joint of each other to drive fixture block 7 through bull stick 8, wherein this paper fixed connection all can adopt the fixed connection mode of welding or integrated into one piece connection to realize.

Specifically, as shown in fig. 1, the top end of the upper pipeline 2 is fixedly connected with a clamping ring 1, the clamping ring 1 is of an annular structure, and the side surface of the clamping ring 1 is provided with a plurality of clamping grooves 10, preferably, the clamping grooves 10 are provided with a plurality of clamping grooves 10, wherein the distance between two adjacent clamping grooves 10 in the plurality of clamping grooves 10 is equal.

Specifically, as shown in fig. 2, a vertical groove 11 is formed at the bottom of the handle 9, and the vertical groove 11 is slidably connected with the rotating rod 8, so that the handle 9 is limited in the rotation direction of the central shaft of the snap ring 1 through the vertical groove 11.

Specifically, as shown in fig. 2, a clamping block 7 is disposed at one end of the rotating rod 8 away from the rotating shaft, and the clamping block 7 is in clearance fit with the clamping groove 10, so that the clamping block 7 and the clamping groove 10 are clamped and fixed with each other.
