AI Technical Summary

Technical Problem

When the existing shear valve is closed, the internal groove body easily causes particles in the water to be blocked at the bottom of the valve core, resulting in gaps in the valve core when it is closed and the blockage cannot be effectively discharged.

Method used

An anti-blocking shear valve is designed, including a shear valve body structure and a blockage discharge structure. The blocked substance discharge structure includes a discharge bottom box, a slag drain tank, a slag drain box, an inner plug pad and a spring to collect and discharge the blocked particulate matter through the water flow.

Benefits of technology

It effectively reduces the possibility of the shear valve core being blocked by particles when it falls, ensures the internal sealing of the valve body and avoids the occurrence of gaps.

Abstract

The utility model relates to the technical field of shear valves, in particular to an anti-blocking shear valve which comprises a shear valve body structure, a shear valve element structure for blocking a water source in a shearing mode is installed in the shear valve body structure, and a blocking matter discharging structure for collecting residues when the shear valve element structure is closed is installed at the bottom of the shear valve body structure. According to the utility model, the screw rod carries out spiral transmission along the interior of the top sealing cover plate, so that the screw rod drives the shearing valve piece to press the shearing valve core piece downwards so as to carry out shearing sealing on the valve body piece, and particles and the like remained in a water source in the middle of the valve body piece are descended and moved in the discharge bottom box by the descended inner inclined frame; and blocked particle impurities are moved to the slag discharging groove through the inner inclined frame, the particle impurities blocking the bottom of the shear valve element part enter the slag discharging box through water flow, the blocked particle impurities are collected, and the problem that gaps exist in the valve body part due to the fact that the shear valve element part is blocked by the particle impurities when the shear valve element part descends is solved.
