AI Technical Summary

Technical Problem

Existing arrow-type valve core devices are corroded when the return spring comes into contact with corrosive liquids, resulting in changes in elastic properties, affecting the opening and closing action of the valve core, and making valve core replacement difficult, increasing maintenance costs and downtime.

Method used

The constraint spring is placed inside the limiting sleeve to avoid direct contact with corrosive liquids, and the valve core can be disassembled and installed by simply rotating the fixed constraint plate and the arrow-shaped valve head.

Benefits of technology

To prevent spring corrosion, ensure precise valve core opening and closing, reduce the risk of safety accidents, reduce production costs, shorten equipment downtime, and ensure production continuity.
