Integrated high-temperature high-pressure metal seal ball valve

Abstract

The invention relates to a valve, in particular to an integrated high-temperature high-pressure metal seal ball valve. The invention adopts the following scheme that: the integrated high-temperature high-pressure metal seal ball valve comprises a valve rod, a valve body, a valve seat and a valve core ball. The valve is characterized in that the valve seat and the valve body are integrally arranged, and a transversal ripple structure is formed at the integral joint of the valve seat and the valve body. By adopting the scheme, the invention overcomes the defects of the prior art and provides a novel integrated high-temperature high-pressure metal seal ball valve with reasonable structure, flexible opening and closing, high efficiency and good seal effect.

Description

Integrated high temperature and high pressure metal seal ball valve technical field The invention relates to a valve, in particular to a high temperature and high pressure metal sealing ball valve. Background technique At present, our valve industry has achieved rapid development, but the existing valves similar to the present invention have the following problems due to their unreasonable structure: 1. The valve core ball and valve seat sealing materials are made of hard chrome, alloy steel and hard Alloy materials are susceptible to erosion, cavitation, and scratches under high temperature, high pressure, and high particle conditions, resulting in seal failure; 2. The valve seat and valve body are set separately, which adds a seal between the valve seat and the valve body. It is very easy to cause leakage of the valve; 3, the seal between the valve body, the auxiliary valve body and the valve stem is easy to leak. Contents of the invention The invention overcomes the...
