AI Technical Summary

Technical Problem

The pressure gauges of existing refrigerant dual-gauge valves are prone to loosening due to accidental contact during use, leading to unstable connections and affecting the safety and efficiency of equipment operation.

Method used

The design employs a connecting assembly consisting of a movable shell, a compression plate, an auxiliary plate, a ball, and a spring. Through the cooperation of the compression plate and the auxiliary plate, the ball is embedded in the annular groove to lock the connector, and the spring provides a continuous upward force to ensure the stability of the connection.

Benefits of technology

This effectively avoids connection loosening caused by external accidental contact, improves the installation stability and replacement efficiency of the pressure gauge, and ensures that the equipment operates under safe and efficient conditions.

Abstract

This utility model relates to an easily replaceable refrigerant dual-gauge valve, belonging to the technical field of refrigerant dual-gauge valves. The easily replaceable refrigerant dual-gauge valve includes: a valve body and a pressure gauge disposed above it; a connecting assembly disposed above the valve body; wherein the connecting assembly includes a movable shell disposed above the valve body; when the movable shell compresses a ball, causing the ball to embed in the annular groove and lock the connector, the position of the movable shell can be locked by setting a compression plate and an auxiliary plate on the connecting assembly, thereby avoiding the loss of the ball-blocking effect and affecting the connection stability of the connector due to accidental external contact with the movable ring; by setting a spring, an upward force can be continuously provided to the movable shell, thereby enabling the movable shell to continuously block the ball, improving the contact effect between the ball and the annular groove, and also improving the locking effect of the connector.
