Abstract

The invention provides a valve. The valve comprises a valve body, a pair of valve plates, a driving mechanism and a moving piece, wherein the valve body is provided with a front channel, a rear channel and a valve cavity; the front channel communicates with the rear channel by the valve cavity; the pair of valve plates is positioned in the valve body and is pivotally connected to a fixing plate ofthe valve body; the driving mechanism comprises a cylinder and a pair of guide columns; the cylinder is fixed on the valve body; the pair of guide columns is movably arranged on a top cover of the valve body; the upper parts of the pair of guide columns are separately connected with an extension shaft of the cylinder; and the moving piece is fixedly mounted on the lower parts of the pair of guidecolumns and is in contact with the pair of valve plates. The valve is novel in structure; and during working, an operator enables the cylinder to work so as to drive the moving piece to move vertically, and then the valve plates are driven to rotate around a hinged shaft to open and close a valve opening. Therefore, the valve has the advantages of simplicity in operation, short opening and closing time, capability of controlling the amount of water flowing through the valve and long service life.

Description

technical field [0001] The present invention relates to a valve. Background technique [0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. It is a device that enables or stops the flow of media (liquid, gas, powder) in piping and equipment and controls its flow. The valve is a control component in the pipeline fluid conveying system, which is used to change the passage section and the flow direction of the medium, and has the functions of diversion, cut-off, throttling, check, diversion or overflow and pressure relief. [0003] Due to the limitations of the selection of the driving structure of the existing valve, the operation of the valve is complicated and the opening and closing time is long, and because there is relative sliding between the sealing surface of the valve plate and the valve seat, long-term friction will cause damage, which affects the performance of the valve. Service life, especially gate valves. ...
