Novel multipurpose ball valve

Abstract

The invention discloses a novel multipurpose ball valve, and relates to the technical field of ball valves. A flow inlet is formed in one side of a valve body, a flow outlet is formed in the other side of the valve body, a valve rod penetrates the top of the valve body, a flow adjusting assembly is arranged on the top of the flow inlet, a wrench is fixedly installed on one side of the top of the valve rod, a ball body is arranged at the position, located inside the valve body, of the bottom end of the valve rod, and a rotating shaft is arranged at the bottom end of the ball body. The novel multipurpose ball valve is scientific and reasonable in structure and convenient to operate; the flow adjusting assembly is arranged, and therefore an adjusting bolt can be adjusted to drive a streamer adjusting plate to adjust up and down, flow adjustment inside the flow inlet is achieved, and a certain buffer effect is achieved; a cutting plane is arranged, and therefore the impact resistance and the wear resistance of the ball body are improved when the ball valve is closed; and a filtering net is arranged inside a water inlet hole, certain filtration treatment on solid particles and impurities in fluid can be carried out, and installing and detachment of the ball valve are simple.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to a novel multipurpose ball valve. Background technique [0002] In my country, ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal, steel and other industries, and occupy a pivotal position in the national economy. It has a 90-degree rotation action, The cock body is a sphere with a circular through hole or channel passing through its axis. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Ball valves are usually divided into three types: pneumatic ball valves, electric ball valves, and manual ball valves. [0003] After searching, the Chinese patent discloses a ball valve (authorized notification number CN205841837U). When the patented technology is installed, the cushion block is fixedly connected...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a new type of multipurpose ball valve to solve the problem that the ball valve proposed in the above background technology is not only complex in structure, but also has a single function, its sealing effect is poor, and it is prone to leakage. At the same time, the sealing surface of the ball is spherical, causing The impact force of the liquid is concentrated on the protruding part of the sphere, which reduces the service life of the sphere, and there is no filter, so the fluid cannot be filtered, which is a problem of poor practicability
