working principle

Valves that automatically control the closing and activation of valves using water forces are commonly used in fire protection and production or living shared water systems. When the fire protection system is started, the pipeline pressure rises and when the set value is exceeded, the production and domestic water pipelines can be automatically shut down. When the fire water supply is over, the pipeline pressure drops to the set value, and the production and domestic water are automatically restored.

Characteristics

- Save on construction costs and daily water usage.
- When fire water is used, the domestic water is automatically turned off to ensure fire water.
  - When the fire is over, immediately restore the domestic water.

product manual

The hydraulic control valve is generally divided into two types: diaphragm type and piston type. The company adopts a diaphragm type with a caliber of Φ600mm or less, and a piston type with a caliber of Φ600mm or more.
The hydraulic control valve is a combination of a main valve and an external needle valve, a sound guide valve, etc., and is transformed into a remote control float valve, a fixed water level valve, a pressure reducing valve, and a slow closing check valve in accordance with the purpose, function and location. , flow control valves, pressure relief valves, electric control valves and pump control valves. The main valve is composed of main parts such as valve body, diaphragm, valve stem assembly and valve seat.
