Three-way valve structure
Three-way valve has two structural forms: L-shaped vertical double channel, the main pipeline is always open, and the valve core is driven by the valve stem to rotate 90, so that the medium flow direction is cut off between the two branch pipelines; The T-shape is three channels, which is suitable for the diversion, confluence or flow direction switching of media. Through different settings, three channels can be connected to each other, or two of them can be connected. The product is powered by compressed air, so that the valve stem drives the valve core to rotate 90 degrees in the valve body, and the medium flow direction can be switched between different flow ports; It can also cooperate with electric positioner to adjust parameters such as pressure, flow rate, temperature and liquid level through 4~20mADC signal input, or adjust and control the proportion of liquid, gas, steam and other media. Can be widely used in petrochemical, gas, light industry, pharmacy, paper, machinery and equipment and other industrial automatic control systems. Used for remote centralized control or local control. Runliu pneumatic three-way valve combines many top international designs and has been adopted by many Fortune 500 companies with excellent performance.
The product quality is mainly reflected in: 1. The valve is made of degreased precision casting and fully CNC lathe; Anti-static device between the ball and the valve body; Anti-falling design of valve stem; Double-disc shrapnel strengthens the valve stem seal; Design of pressure balance hole of valve body: ISO52 1 1 platform design; Adopt advanced four-seat sealing structure. Two? The actuator is imported, with many world patents, surface anticorrosion treatment, adjustable switch degree, multifunctional position indication, large output torque, compact structure, stable action and flexible operation; Various international standard accessories are interchangeable.

Working principle of refrigerator three-way valve
There are mainly L-type and T-type three-way valves in refrigerators. L-shaped refrigerator three-way valve mainly plays a distribution role. The principle is one in and one out, a leads to b or a leads to c, that is, only two orthogonal pipes can be connected. T-type refrigerator three-way valve is divided into confluence type and shunt type. T-type refrigerator three-way valve is more complicated than L-type refrigerator. T-type refrigerator three-way valve has four seats, while L-type refrigerator has two seats.
The three-way valve of the three-way refrigerator has two inlets and one outlet. This structure is usually suitable for working conditions where two different media are mixed together. If the pressure at the inlet end is different from or less than the pressure at the outlet end, a check valve should be installed in front of the valve. The three-way valve of T-refrigerator has one inlet and two outlets. This structure is the most commonly used valve in refrigerator three-way valve, and it is also widely used. General refrigerator three-way valve manufacturers have a lot of cash.
Use of three-way valve in refrigerator
The three-way valve of refrigerator is widely used in petroleum, chemical industry, natural gas, power station, metallurgy, national defense research and other fields; The main medium is water; Steam; Oil; Gas; Mud; Corrosive medium; Liquid metals and radioactive fluids. ? The working pressure of the valve ranges from 0.00 13MPa to 1000MPa? Ultra-high pressure, working temperature from ultra-low temperature of -269℃ to high temperature of 1430℃.
Refrigerator three-way valve price
Prices range from a few yuan to tens of yuan. The three-way valve body has three ports, one inlet and two outlets (left inlet, right outlet and lower outlet). Different from ordinary valves, there is an outlet at the bottom. When the internal spool is in different positions, the outlet is different. For example, when the valve core is in the lower part, it is connected left and right. For example, when the valve core is in the upper part, the right outlet is blocked and the left and right ports are connected. Because the left port and the right port are not on a horizontal line. When the high-pressure heater is disconnected in an emergency, the valve is closed and the water supply is bypassed.
Having said so many structural problems of the three-way valve, if compared with the ordinary valve, the three-way valve has one more flow port than the ordinary valve. Don't underestimate this small flow port, it is still very useful. The structure of three-way valve is also divided into L type and T type. I think readers will be familiar with the structure of the three-way valve after reading the detailed explanation of the three-way valve prepared by Bian Xiao, and they can also worry about what kind of valve to buy. I hope everyone will support Tuba Rabbit, and we will work harder.
