Abstract

The invention relates to a filtering type anti-blocking valve which comprises a left connector, two conveying units, a detachable unit, two shunt tubes, a communicating pipe, an opening and closing ball body, a right connector and a linkage unit. The invention can solve the problems that when the valve is closed, fluid is trapped inside the valve body, a smooth layer is formed on the inner wall of the valve body in the long term, and because the traditional valve has no filtering function, after impurities in the fluid enter the valve along with the fluid, one part of the impurities can be adhered to the smooth layer, and the other part of the impurities can be accumulated on parts in the valve, so that the difficulty of opening and closing the valve at the later stage is increased, and the like.

Description

Filtering type anti-blocking valve

Technical Field

The invention relates to the field of valves, in particular to a filter type anti-blocking valve.

Background

The valve is a device for controlling the direction, pressure and flow of fluid, can be used for controlling the flow of various fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like, is a control part in a pipeline fluid conveying system, is used for changing the section of a passage and the flow direction of the media, and has the functions of diversion, cut-off, throttling, non-return, flow splitting, overflow pressure relief and the like.

When the valve is closed, the fluid can be detained inside the valve body, valve body inner wall can form the one deck smooth layer of a long time, because the smooth layer has certain thickness, again because traditional valve does not have the filtration function, impurity in the fluid follows behind the fluid entering valve, partly impurity can the adhesion on the smooth layer, long-term accident can cause the condition of jam, the impurity of another part can be piled up on the part in the valve, lead to the degree of difficulty increase of later stage switch valve, need get off valve whole dismantlement when clearing up the smooth layer, greatly increased work burden, and during the clearance, the fluid can not continue to flow.
