Multifunctional electric control pressure release device, as well as electric control system and electric control method thereof

Abstract

The invention discloses a multifunctional electric control pressure release device which comprises two three-way valves (2) that are communicated with each other, wherein the two three-way valves (2) are communicated with a standpipe pressure release valve (7) and a unit pressure release valve (6) respectively, and communicated with a one-way valve (3); and a center line of the one-way valve (3) and center lines of the three-way valves (2) are in the same straight line. The invention further discloses an electric control system and an electric control method based on the multifunctional electric control pressure release device. The pressure release device can solve the problems of insufficient pressure release, long pressure release time and the like of the existing pressure release device during pressure release; with the adoption of the standpipe pressure release valve and the unit pressure release valve, gas pressure is released from two pressure release ports, and the pressure release efficiency is improved; and with the adoption of the one-way valve, gas in the pressure release device cannot flow back, the service life of equipment is ensured, harms arising from the backflow gas are avoided, the gas pressure can be monitored, and valve opening can be mastered accurately.

Description

technical field [0001] The invention relates to a multifunctional electric control pressure relief device, an electric control system and an electric control method thereof. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel valves, chrome molybdenum vanadium steel valves, duplex steel valves, plastic valves,...
