High-pressure-difference intelligent regulating valve

Abstract

The invention discloses a high-pressure-difference intelligent regulating valve. A mounting base is mounted below a valve seat of an S-shaped runner in a valve body; a pressure sleeve is arranged above the valve seat; a multi-channel multi-grade maze type runner is arranged on each layer of metal disc sheets of a middle section maze valve sleeve assembly on the side wall, so that medium flow speedis controlled while pressure is reduced stage by stage; the surface hardness is increased through a nano diamond coating, processing precision and processing efficiency of the disc sheet runner is improved through an electrolytic composite milling processing technology and an electrochemical mechanical composite polishing technology, and service life is prolonged; and working condition data of the regulating valve is monitored in real time through an intelligent detecting system and a remote monitoring system, working conditions are established, a working time-valve damage degree module is established, a clinical operation state of the valve is analyzed, and faults are pre-warned, so that intelligent control needs are adapted.

Description

technical field [0001] The invention relates to a high pressure difference intelligent regulating valve. Background technique [0002] In the industrial industry, there are harsh working conditions of high temperature and high pressure critical state. The high temperature and high pressure critical state will have impact and friction on the internal structure of the valve, which will easily cause damage to the sealing performance of the valve. The valve seat and valve core are easy to wear and even destroy the valve. Fluid channel structure, and in the critical state of high temperature and high pressure, part of the fluid medium is extremely penetrating. Once leaked, it will burn people and suffocate the space where it is located, which is extremely destructive to people and property. There are high requirements for heat dissipation performance during work, and the flow and pressure regulation are unstable under harsh working conditions, which affects the service life of th...
