Solenoid valve isà gì?

Solenoid valve or also known as solenoid valve solenoid valve isà type of stop valve that opens thanks to the force of the solenoid coil. Solenoid valve isà a redundant device. According to the structure, the solenoid valve has can be stop valve (1-way type) or transfer valve (multi-way). Solenoid valves are used in water and air systems. Next, the refrigerant gas name of the solenoid valve corresponds to the heating system. such as water solenoid valve, air solenoid valve; nén, the air system solenoid valve nén, solenoid valve for air conditioning system, automatic solenoid valve...

- One-way solenoid valve (otherwise blocking valve) is used to automatically open and close liquid or gas, refrigerant vapor remotely.

- 2 or 3-way solenoid valve; (transfer valve) used to automatically change direct, indirect or combined openings.

- Direct-opening solenoid valve type of valve that only uses electromagnetic force to open the clape (direct operation)

- Direct-opening solenoid valve type of valve that only uses electromagnetic force to open the auxiliary clape, the main clape is opened by using liquid or air. goes through the auxiliary clape (servo operation)

- Open-way solenoid valve coordinates the flow. valve type có The structure combines the characteristics of direct or indirect valve opening both by electromagnetic force and by the pressure of the liquid or gas. of flow (forced servo operation) or pilot

- Solenoid valve is normally closed or normally open. By location lá valve when operating needs to be The card divides the type of valve into normally closed or normally open

- The valve is usually loose. valve type when the solenoid coil does not have electricity and opens when the solenoid coil electricity. (NC – Normal Closed)

- The valve usually opens in reverse. The type of valve that opens when winding is not necessary. electricity and At the same time, the solenoid coil has power (NO – Normal Open)

- Direct acting solenoid valves usually have small flow capacity for both air and water andà liquid. Ordinary valve line < 10mm

- On the valve seat of valve stem 1 there is layoutí outlet for each substance. Figure 2 shows the type of connection of flared copper pipes with threaded and threaded ends. snail hat but also có can có Pipe connection type using silver joints according to the instructions. make. This type of connection is not used here. Only used for large solenoid valves.

Clape 3 of the valve opens on the seat of valve 2 thanks to the up-and-down movement of the iron rod 5 when it is closed. electricity or no electricity electricity. Tube 4 serves as both a guide tube for iron tube 5 and as a barrier separating the internal liquid space from the external environment. It is fixed and as a result, it also needs to be valved. Pipe 4 is made from non-magnetic materials to ensure the complete working of the iron. Along with 4-valve tube fixed loop 6, the internal cavity of the valve is completely connected to the external environment.

4-way tube bed electromagnetic coil. To ensure the tightness of the coil, rubber is used to seal the 11-out contact connector. The solenoid coil cover 7 is fixed to the valve stem by screw 9.

- If there is no electricity into the coil due to lò xo 13 comes out and agrave; Due to the weight of the iron bar falling down, the valve gate is closed (for NC valves - usually closed)

- When energized, the coil generates a magnetic field that attracts iron to the upper part, opening the valve's opening to allow refrigerant gas to pass through.

- To reduce vibration and vibration; The noise of the iron wire when energizing the coil into the AC network is attached to a fixed wire 6, an eyelet 10 on the shoulder. vascular segment.
