Abstract

The invention discloses a rust-proof and durable gate valve, which includes a pipe. A first fixed pipe is fixedly connected to the top of the pipe, a second fixed pipe is provided on the top of the first fixed pipe, and a second fixed pipe is provided inside the pipe. bezel. In the present invention, a pipe, a first fixed pipe, a second fixed pipe, a baffle, a bearing, a clamping mechanism, a third fixed block, a second transmission rod, a second clamping block, a screw, a rotating mechanism, a sleeve, a turntable, Pull ring, clamping rod, first fixed rod, second fixed rod, card box, pressing block, third fixed rod, fourth fixed rod, first transmission rod, first fixed block, fifth fixed rod, sliding rod, The combined use of the second fixed block, the first clamping block and the filter screen solves the problem that the filter screen of the existing gate valve is easily blocked during use and is inconvenient to disassemble, thus causing the gate valve to be unusable. This anti-rust and durable gate valve can It has the advantage of easy disassembly, which improves the practicality of the gate valve.

Description

technical field [0001] The invention relates to the technical field of gate valves, in particular to a rust-proof and durable gate valve. Background technique [0002] The gate valve is a gate of the opening and closing part. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed. The gate moves linearly with the valve stem, which is determined by the position of the gate, that is, the stroke. , In some gate valves, the stem nut is set on the gate plate, and the rotation of the hand wheel drives the valve stem to rotate, and the gate is lifted. This kind of valve is called a rotary stem gate valve, or a dark stem gate valve. [0003] Gate valves are used in daily life, but the filter screen of existing gate valves is easy to clog during use, and it is inconvenient to disassemble, resulting in the phenomenon that the gate valve cannot be used, which is inconvenient for users to use and reduce...
