Trench electric solenoid valve

Trench electric solenoid valve

Groove electric solenoid valve is an electric control valve that uses groove connection method and is widely used in water supply and drainage, fire protection and other systems. Here is an introduction about it:

1. Structure and Principle

Groove electric solenoid valves are usually composed of components such as valve body, solenoid coil, piston or valve core. Its working principle is to use an electromagnetic coil to power on or off, generating magnetic force to drive the valve core to move, thereby achieving the opening or closing of the valve to control the on/off of the fluid.

2. Characteristics

• Convenient connection: Adopting groove connection and fixed with pipe clamps, the installation speed is fast, without welding or threaded connection, which can effectively solve the stress problem between components.

• Stable operation: It is mostly controlled by hydraulic principles, with a novel and reasonable structure, stable and reliable operation, and can avoid water hammer impact.

Bidirectional sealing: Reliable sealing, not limited by the flow direction of the medium, with bidirectional sealing performance, large overcurrent area, and low flow resistance coefficient.

Remote control: It can remotely open and close the pipeline system based on electrical signals, achieving remote operation and accurate and fast control response.

3. Technical specifications

• Pressure range: The nominal pressure generally includes 1.0MPa, 1.6MPa, 2.5MPa, etc.

• Medium temperature: usually suitable for situations where the medium temperature is ≤ 80 ℃.

• Power supply voltage: AC 220V or DC 24V can be selected.

4. Application Fields

Mainly used in automatic water supply systems for industrial and mining enterprises, fire protection systems, water tanks, water towers in high-rise buildings, and can also be used for circulating water supply in atmospheric boilers and other occasions. In addition, it is widely used in pipeline systems in urban water supply and drainage, petroleum, chemical and other industries.

5. Installation precautions

During installation, it is necessary to ensure that the pipeline is clean and avoid debris damaging the sealing surface or blocking the valve core. Valves can be installed at any position in the pipeline, but they should be easy to operate and maintain. At the same time, it is necessary to ensure the sealing of the groove connection to prevent leakage.
