Brief introduction of three-flower four-way valve

The three-flower four-way valve is a control valve with four ports.The four-way valve is an indispensable part of the refrigeration equipment. Its working principle is that when the solenoid valve coil is in the de-energized state, the pilot slide valve is driven by the right compression spring to move to the left, and the high pressure gas enters the capillary tube and enters the right piston chamber. On the one hand, the gas in the left piston cavity is discharged. Due to the pressure difference between the two ends of the piston, the piston and the main slide valve move to the left, so that the exhaust pipe communicates with the outdoor unit pipe, and the other two pipes communicate to form a refrigeration cycle.

Working principle of three-flower four-way valve

The three-flower four-way valve is an important part of the heat pump type air conditioner. It has the function of changing the flow direction of the air conditioner refrigerant, so that the air conditioner can realize the cooling and heating function without adding other heating elements. It can play its role, mainly due to the working principle of the four-way valve, as shown below:

The role of three-flower four-way valve

The role of the three-flower four-way valve is an aspect that can not be ignored, it plays a very important role in the air conditioner. The three-flower four-way valve consists of three parts: the pilot valve, the main valve and the solenoid coil. It consists of four identical one-way valve groups for switching between cooling and heating. If the directions are opposite, the cooling and heating cannot be converted mutually, and cooling or heating cannot be performed.

How does the gas-liquid separator perform separation?

The gas-liquid separator, friends who have used it should be familiar with it, because the gas-liquid separator is more common in our daily life. So, how does the gas-liquid separator perform separation? I believe some friends don’t know very well, let’s take a look with the editor below!

The working principle and method of gas-liquid separator

The gas-liquid separator is usually installed before the steam turbine to protect the steam turbine blades from wet steam, pipe fouling and other destructive solid impurities. The gas-liquid separator can remove water and solid particles above 10μm, and the efficiency can reach 99%.

If the four-way valve fails, repair it like this

In the process of using the four-way valve, many users will find that the air-conditioning system will have two kinds of failures, that is, insufficient flow and poor commutation. So what are the reasons for these two failures? If it does, how should it be repaired? If you want to know, just listen to the editor to answer it for you.

The working principle of four-way valve cooling and heating

Speaking of the four-way valve, many people may not know it, but it is an indispensable working part in refrigeration equipment. The four-way valve, as its name implies, is a control valve with four ports. When the solenoid valve coil inside is de-energized, the spool valve of the four-way valve will move leftward under the action of the right pressure spring. Then the high-pressure gas will enter the capillary tube and transfer to the piston chamber at the right end. Then the gas inside the left cavity will be discharged, and a certain pressure difference will be formed at the left and right ends, so that the exhaust pipe can be connected with the outdoor machinery, and a refrigeration cycle will be formed.
