AI Technical Summary

Technical Problem

Existing high-temperature control valves suffer from problems such as excessively high valve plate and stem temperatures leading to reduced service life, valve plate deformation due to high temperatures resulting in incomplete closure, and poor sealing performance causing easy leakage, which affect the stability and safety of industrial pipeline systems.

Method used

The valve stem and valve plate assembly are designed with a hollow structure, which, together with the air inlet, air outlet and exhaust port, forms a gas circulation cooling system. It is equipped with a sealing device to improve the sealing performance, and the structural stability is enhanced by limiting parts and reinforcing ribs.

Benefits of technology

It effectively reduces the temperature of the valve stem and valve plate, prevents deformation, improves sealing performance, extends service life, and ensures stable operation and safety in high-temperature environments.

Abstract

A new high temperature regulating valve, including valve body, valve stem assembly, valve plate assembly, power device and sealing device, the valve body is provided with valve cavity, the valve plate assembly is arranged in the valve cavity, the sealing device is arranged between the valve plate assembly and the valve body, the sealing device seals the valve plate in the closed case, the valve stem assembly includes first valve stem and second valve stem, the first valve stem and the second valve stem are provided with hollow structure, the first valve stem and the second valve stem are provided with air inlet and air outlet.The design is provided with first valve stem and second valve stem for hollow structure, and through the cooperation of air inlet, air outlet and exhaust hole, the effective cooling of valve stem assembly and valve plate assembly is realized, and the effect of gas circulation cooling is formed.This cooling mode not only reduces the temperature of valve stem and valve plate, prevents deformation and damage caused by high temperature, but also prolongs the service life of the valve.
