The three-way valve is a control component in the fluid conveying system, with functions such as cut-off, regulation, diversion, prevention of backflow, voltage stabilization, diversion or overflow. Three-way 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. Next, the editor will introduce the working principle of the three-way valve and the use of the three-way valve.
Working Principle:
The three-way valve is mainly divided into L-type and T-type. The L-type three-way valve mainly plays a distribution role. The principle is one in and one out. pipeline. The T-type three-way valve is divided into two types: confluence and diversion. The T-type structure is more complicated than the L-type. The T-type three-way valve has a four-sided valve seat, while the L-type has a two-sided valve seat. The confluent T-type three-way valve is two in and one out. This structure is generally suitable for working conditions where two different media are mixed together. If the pressure at the inlet end is different or the pressure is lower than that at the outlet end, a check valve should be installed in front of the valve. The shunt T-type three-way valve is one in and two out. This structure is the most commonly used valve in the three-way valve, and the general three-way valve manufacturers are mostly in stock.
The Main Purpose:
Three-way valves are widely used in petroleum, chemical, natural gas, power stations, metallurgy, national defense scientific research and other fields; the main media are water, steam, oil, gas, mud, various corrosive media, liquid metal and radioactive fluids and other types Fluid flow; the working pressure of the valve can be from 0.0013MPa to 1000MPa, and the working temperature is from the ultra-low temperature of -269 degree to the high temperature of 1430 degree .
