AI Technical Summary

Technical Problem

In the existing technology, it is difficult to accurately determine the service life and status of solenoid valves in the pneumatic shut-off valve of the engine test bench, and it is also difficult to manually judge the operation of multiple solenoid valves.

Method used

A valve control system with monitoring and counting function was designed, including a solenoid valve, a pneumatic shut-off valve, and a solenoid valve switching feedback device. The number of solenoid valve actions and status are monitored in real time through a mechanical counter and a battery-powered indicator light assembly. Low-pressure counting and display are achieved through pneumatic circuit design.

Benefits of technology

It enables real-time monitoring of the working status and recording of the number of actuations of multiple solenoid valves, accurately determines the service life of solenoid valves, and improves the reliability of the test and the ease of operation for the staff.

Abstract

This utility model provides a valve control system with a monitoring and counting function, comprising at least: a solenoid valve, a pneumatic shut-off valve, and a solenoid valve switching feedback device; the pneumatic shut-off valve comprises at least a first cylinder and a first piston rod; the solenoid valve switching feedback device comprises at least a second cylinder, a second piston rod, and a mechanical counter mounted on the outer side of the second cylinder; the solenoid valve comprises at least an inlet, a first outlet, and a second outlet, the first outlet being connected to the first cylinder's working chamber and the second cylinder's working chamber respectively, and the second outlet being connected to the first cylinder's return chamber and the second cylinder's return chamber respectively; the solenoid valve is controlled to open the first outlet and close the second outlet, the first cylinder's working chamber being filled with air to drive the first piston rod to extend, thereby opening the pneumatic shut-off valve; the second cylinder's working chamber being filled with air to drive the second piston rod to extend and press the counting contact of the mechanical counter to count, thereby recording the number of times the pneumatic shut-off valve has opened.
