AI Technical Summary

Technical Problem

The existing pneumatic two-position three-way diaphragm valve requires shutdown for cleaning when the filter unit is clogged, which affects work efficiency.

Method used

A filter plate and guide rod structure with an inclined setting was designed. Combined with an electric telescopic rod and piston plate, it can automatically clean impurities without affecting the use of the valve body. Impurities are discharged by injecting liquid, and air replacement is achieved by using a solenoid valve and an exhaust valve.

Benefits of technology

It enables automatic cleaning of impurities from the filter plate without shutting down the machine, improving work efficiency and extending the service life of the valve body.

Abstract

The utility model provides pneumatic two position three way diaphragm valve relates to diaphragm valve technical field, including valve body, the water inlet end of valve body is installed with built -in tube, the pipe orifice of built -in tube side to valve body diaphragm is inclined to set up and is installed with filter plate, the filter plate top edge is close to valve body water inlet end setting and filter plate bottom edge is close to valve body diaphragm setting, when outside board and inside board respectively stick to filter plate outside and inside, the hollow part of built -in tube is located in the space separated by the impurity accumulation, at this moment, through electric telescopic link elongation, piston plate can realize descending in the impurity removal cylinder, until piston plate extends the impurity removal pipe, at this moment, the impurity that filter plate bottom accumulated can drop and discharge through the impurity removal cylinder, realizes the impurity cleaning of internal filtration under the condition of not influencing valve body use.
