Valve with anti-rotation function

Abstract

The invention discloses a valve with an anti-rotation function. The valve with the anti-rotation function comprises a valve body, wherein a transmission rod is arranged on the left side of the valve body. According to the valve with the anti-rotation function, a first clamping block, a second clamping block, a clamping ring, a rotary table, a telescopic mechanism and a limiting mechanism are usedin cooperation, and the clamping ring drives the first clamping block to be clamped with the second clamping block of the rotary table, so that rotation of the rotary table and the transmission rod isavoided; the clamping ring can be effectively and automatically clamped on the rotary table through the telescopic mechanism; the position of the clamping ring can be adjusted through the limiting mechanism so that a user can reversely rotate the rotary table for operation, and the problems that in the long-term using process of an existing butterfly valve, a rotary table needs to be forward andreversely rotated, abrasion of components in a valve can be caused by a transmission rod, and rotation of the transmission rod can be caused by water flow scouring are solved; and the valve with the anti-rotation function has the advantage of being able to prevent rotation.

Description

technical field [0001] The invention belongs to the technical field of valve anti-rotation, in particular to a valve with anti-rotation function. Background technique [0002] The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting and throttling on the pipeline. The opening and closing parts of the butterfly valve are A disc-shaped butterfly plate rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. [0003] Butterfly valve, also known as flap valve, is a regulating valve with simple structure, which can be used for switch control of low-pressure pipeline medium. The technical problem is: the butterfly valve needs to rotate the turntable in the forward and reverse direction during the long-term use. When the transmission rod drives the internal parts of the valve to cause wea...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problems existing in the prior art, the present invention provides a valve with anti-rotation function, which has the advantages of anti-rotation, and solves the problem that the existing butterfly valve needs to rotate the turntable in the forward and reverse directions during the long-term use. While the rod drives the internal parts of the valve to cause wear and tear, it is easy to cause the phenomenon that the driving rod rotates under the washing of the water flow
