Hydraulic valve with anti-blocking self-dredging mechanism

Abstract

The invention discloses a hydraulic valve with an anti-blocking self-dredging mechanism, and belongs to the technical field of hydraulic valves. The hydraulic valve comprises a hydraulic mechanism, alimiting mechanism sleeves the top of the hydraulic mechanism, the bottom of the limiting mechanism is movably connected with a base through a clamping mechanism, flushing mechanisms are arranged on two sides of the hydraulic mechanism, and one side of the hydraulic mechanism is fixedly connected with an anti-blocking mechanism. According to the hydraulic valve, a filter plate can be driven to rotate around a pin shaft through a second fixing block and push a first fixing block and a piston to move upwards through impact, a telescopic rod extends to drive an extrusion plate to extrude, fix andlimit a first valve pipe and a second valve pipe on the two sides, then polarization of the first valve pipe and the second valve pipe can be avoided, the overall working stability is remarkably improved, noise pollution to the nearby environment is reduced, internal hydraulic oil impurities are prevented from accumulating and blocking an inner cavity of a valve body, the working state stabilityis improved, and use requirements are met.

Description

technical field [0001] The invention belongs to the technical field of hydraulic valves, in particular to a hydraulic valve with an anti-clogging self-dredging mechanism. Background technique [0002] In the automatic production line, the hydraulic valve is one of the essential components. The hydraulic cylinder is an automatic component operated by pressure oil. It is controlled by the pressure oil of the pressure distribution valve. Distance control on-off of oil, gas and water pipeline system of hydropower station. The purity of the valve pressure oil in the hydraulic valve determines the working state of the hydraulic valve. [0003] In the prior art, most hydraulic valves cannot flush the inside of the valve body, which leads to the accumulation of oil in the valve body and easily leads to blockage of the valve body, which affects the working stroke of the hydraulic valve, and the increase in the pressure of the oil circuit during the operation of the hydraulic valve w...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that most hydraulic valves cannot flush the inside of the valve body, which leads to the accumulation of oil dirt inside the valve body and easily leads to blockage of the valve body, which affects the working stroke of the hydraulic valve. The increase of motion pressure will cause the valve wall to resonate, which will lead to the increase of the noise of the valve body, which obviously affects the production environment of the process line, and the valve body is mostly assembled by bolts, which leads to the problem of inconvenient replacement and maintenance of the valve body.
