Abstract

The invention provides a low-torque electric gas gate valve, which includes a mounting bracket, a power unit, a transmission unit, a moving gate unit and a gate valve body, wherein the power unit is fixedly installed on the top of the mounting bracket, including a control The transmission unit is used to convert the rotary motion output by the power unit into linear reciprocating motion; the moving gate unit is used to receive the command of the controller, and change the area of ​​the gate sealing surface according to the command received, so The moving gate unit is connected with the transmission unit through a coupling; the mounting bracket is fixedly installed on the gate valve body, which solves the problem that the gate valve with a traditional structure requires a large amount of time when opening or closing the gate valve during application The problem of operating torque reduces the operating torque when operating the gate valve, and the area of ​​the gate sealing surface is controllable.

Description

technical field [0001] The invention relates to the technical field of gate valve control, in particular to an electric gate valve capable of realizing automatic adjustment of a sealing surface and having low torque. Background technique [0002] Gas gate valves are essential equipment for the safe operation, maintenance, transformation and development of gas transmission and distribution and storage systems. There are the following problems in the application of gate valves with traditional structures: 1. When the gate is closed, it must rely on external force to force the gate The valve seat is used to ensure the tightness of the sealing surface, so it is easy to cause erosion between the sealing surfaces, which will cause problems such as poor closure and damage to the joint surface, which will cause leakage of the fluid medium and affect the quality of the pipeline; 2. When When the opening of the gate valve is above 10%, the axial force of the gate valve, that is, the o...
