Abstract
The invention discloses a rust-proof and durable gate valve. The rust-proof and durable gate valve comprises a pipeline, wherein the top of the pipeline is fixedly communicated with a first fixed pipe; a second fixed pipe is arranged at the top of the first fixed pipe; a baffle is arranged in the pipeline. Through cooperation of the pipeline, the first fixed pipe, the second fixed pipe, the baffle, a bearing, a clamping mechanism, a third fixing block, a second transmission rod, a second clamping block, a screw, a rotating mechanism, a sleeve pipe, a rotating disc, a pulling ring, a clamping rod, a first fixing rod, a second fixing rod, a clamping box, a pressing block, a third fixing rod, a fourth fixing rod, a first transmission rod, a first fixing block, a fifth fixing rod, a sliding rod, a second fixing block, a first clamping block and a filtering screen in use, the problem that the gate valve cannot be used caused by high possibility of blockage of the filtering screen and inconvenience in disassembly of the gate valve in the existing gate valve are solved; the rust-proof and durable gate valve has the advantage of convenience in disassembly; the practicability of the gate valve is improved.
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...
