AI Technical Summary

Technical Problem

The existing mechanical valve core lacks a limiting structure, which causes position deviation due to misoperation or inertia, resulting in air pressure leakage.

Method used

A pneumatic booster oil pump stroke valve is designed. The limit structure includes a limit part, a positioning part and a damping ring. The elastic squeezing effect of the damping ring keeps the mechanical valve core in a specific position to prevent deviation.

Benefits of technology

Effectively limit the position of the mechanical valve core to avoid deviation caused by misoperation or inertia, ensuring air pressure stability.

Abstract

The utility model discloses a pneumatic booster oil pump stroke valve, which relates to the technical field of mechanical valves and is used for being matched with a valve core of a mechanical valve, a limiting structure comprises a limiting part, a positioning part and a damping ring, the lower end of the limiting part is integrally connected with the positioning part, and the lower end of the positioning part is integrally connected with the damping ring. The damping rings are arranged in the positioning part and the limiting part, and the diameter of the limiting part is larger than that of the positioning part. According to the mechanical valve, through the arrangement of the limiting structure, the position of the valve element of the mechanical valve can be limited, so that the valve element of the mechanical valve can be kept at a certain position, and the situation that the position of the valve element of the mechanical valve deviates due to misoperation or the inertia effect is avoided.
