AI Technical Summary

Technical Problem

The seals of electric valves are at risk of falling off or dislodging due to rapid fluid expansion, leading to internal leakage and seal failure.

Method used

The design employs a first protective sleeve and an elastic element. The first protective sleeve is fitted around the outer periphery of the valve stem and abuts against the stop face, reducing the impact of the medium on the sealing assembly and preventing the sealing assembly from falling off or dislodging.

Benefits of technology

This improves the reliability of the sealing components of the electric valve, reduces the probability of sealing components falling off or dislodging, and enhances sealing performance.

Abstract

This application discloses an electric valve, including a valve body component, a valve stem assembly, and a first sealing assembly. The valve body component includes a first interface portion, a second interface portion, and a first valve port channel. The first interface portion can communicate with the second interface portion through the first valve port channel. At least a portion of the valve stem assembly is located within the valve body component. The valve stem assembly includes a valve stem. The first sealing assembly is sleeved on the valve stem and is axially limited to the valve stem. The electric valve includes a first protective sleeve and an elastic element. The first protective sleeve is sleeved on the outer periphery of the valve stem and can slide axially relative to the valve stem. The elastic element abuts against the first protective sleeve. The valve body component includes a first stop portion facing away from the first valve port channel, and the first protective sleeve can abut against the first stop portion. This electric valve has reliable sealing performance.
