Embodiment

[0042] see Figure 1-8 , a ball valve for reducing the impact effect, comprising a ball valve body 100, a ball valve body 300 is arranged inside the ball valve body 100, a valve stem 200 is rotatably connected to the inside of the ball valve body 100, and the lower end of the valve stem 200 is fixedly connected with the upper end of the valve ball body 300 , the upper side of the ball valve body 100 is provided with a handle 400, the upper end of the valve rod 200 is fixedly connected with the handle 400, the outer end of the valve ball 300 is provided with a buffer dispersion mechanism 500, and the inside of the valve ball 300 is provided with a facing pressure mechanism 600 , the lower end of the ball valve body 100 is equipped with a pneumatic dispersing mechanism 700. In this solution, when the fluid impacts on the valve ball body 300, the impact force received by the valve ball body 300 is dispersed by buffering the dispersion layer of the dispersion mechanism 500, and the...

Abstract

The invention discloses a ball valve capable of reducing the impact effect, and belongs to the field of ball valves. According to the scheme, when fluid impacts on a valve ball body, the impact force borne by the valve ball body is dispersed and absorbed through a buffering and dispersing mechanism, the impact force transmitted to the valve ball body is relieved, and the impact effect is reduced; meanwhile, the impact force transmitted to the valve ball body drives the opposite abutting mechanisms to extrude air in the valve ball body to be sprayed out, reaction blowing is carried out on subsequent fluid impact, the blowing force and the fluid impact force are counteracted, the subsequent impact effect is effectively reduced, the valve ball body is not prone to damage, and the service life of the valve ball body is prolonged. And the pneumatic dispersing mechanism releases a large amount of carbon dioxide gas and sprays the carbon dioxide gas upwards under the impact effect, upward force is applied to follow-up flowing fluid, the follow-up flowing fluid is dispersed and is not prone to being concentrated together, and therefore impact force is relieved and dispersed, the valve ball body is not prone to being damaged under the continuous impact effect, and the protection effect is enhanced.

Description

technical field [0001] The invention relates to the field of ball valves, in particular to a ball valve with reduced impact. Background technique [0002] Ball valve, the opening and closing part is driven by the valve stem and rotates around the ball valve axis. It can also be used for fluid adjustment and control. Among them, the hard-sealed V-shaped ball valve has a V-shaped ball core and a hard-facing metal valve seat There is a strong shear force between them, especially suitable for media containing fibers, tiny solid particles, etc., and the multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of media on the pipeline, but also close One channel connects the other two channels. [0003] When the ball valve stops the flowing fluid, the fluid still keeps flowing until it impacts on the opening and closing parts. Over time, the opening and closing parts are prone to damage under the impact, which reduces the adjustme...
