Thrust valve

Abstract

The invention discloses a thrust valve. The main body structure of the thrust valve is a cylindrical valve shell, wherein a braking shaft is designed in a manner vertical to the length surface of the valve shell; a supporting and positioning plate is fixed on the inner wall of the valve shell; a positioning rod is connected to the supporting and positioning plate; a steering transmission mechanism is fixed in the valve shell through the other end of the positioning rod; the braking shaft is an input shaft of the steering transmission mechanism; an outer edge conical valve plate which is vertical to an output shaft of the steering transmission mechanism is connected to the output shaft; the outer edge of the outer edge conical valve plate is an inclined surface; an inner edge wide-mouth flange is arranged at one end of the valve shell; the closing of a valve body is realized under the cooperation of the inner edge wide-mouth flange and the outer edge conical valve plate; and conical decontamination teeth are designed on the outer edge circumference of the outer side vertical wall of the outer edge conical valve plate. The thrust valve has the advantages that: after the thrust valve is opened or closed, a good sealing effect is achieved, and a decontamination function is realized simultaneously. The thrust valve has wide application, and is particularly suitable for braking large and middle-sized sewage-carrying gas-liquid pipelines.

Description

technical field [0001] The invention relates to a pipeline switch valve, in particular to a valve for controlling the flow of gas and liquid carrying dust and dirt in pipelines. Background technique [0002] At present, there are many kinds of pipeline valves and are widely used, but they not only control the flow of gas and liquid in the pipeline, but also control the flow of gas and liquid carrying dust and dirt. Valves for the flow of dirty media entered the market early. With the continuous development of science and technology, the pipeline has become the artery for transporting gas and liquid all over the world. The key to controlling the movement of the flowing medium in the pipeline is to set up valves. There are many types of existing valves, mainly including ball valves, plate valves and butterfly valves. , Each has distinct characteristics, but all have their fatal disadvantages. The ball valve is not flexible to rotate, the plate valve needs to be rotated dozens...

Problems solved by technology

[0002] At present, there are many kinds of pipeline valves and are widely used, but they not only control the flow of gas and liquid in the pipeline, but also control the flow of gas and liquid carrying dust and dirt. Valves for Dirty Media Flow Come to Market Early

With the continuous development of science and technology, the pipeline has become the artery for transporting gas and liquid all over the world. The key to controlling the movement of the flowing medium in the pipeline is to set up valves. There are many types of existing valves, mainly including ball valves, plate valves and butterfly valves. Each has distinct characteristics, but each has its fatal disadvantages. The ball valve is not flexible to rotate, the plate valve needs to be rotated dozens of times to switch in place, and the butterfly valve is only suitable for controlling the flow of low-temperature medium.
