Characteristics and uses of pneumatic quick shut-off valves

Quick shut-off valve features

The quick shut-off valve is a normally open pulse-trigger type solenoid valve. The fast shut-off valve produced by Shanghai Voto Valve has simple structure, sensitive response, reliable operation, self-locking accident and manual reset function, and has been applied by various industries. Mainly focused on the following aspects:

1. The valve is in the normally open state during daily work, and the solenoid valve coil is in the power-off state and does not consume electrical energy.

2. When the accident occurs, the valve coil is energized instantaneously, triggering the valve to close quickly and enter the self-locking state. At this time, even if the power is removed, the valve is still in a self-locking state and will not automatically re-open.

3. The valve adopts pilot-operated valve flap, which is easy to open. Even if the pressure reaches 6bar, it is very easy to open. The diameter is larger than DN125. The lever handle is used to make the valve reach the labor saving and fast.

Quick shut-off valve use

1. It is connected with the flammable gas leakage monitoring instrument. When the instrument detects the leakage of flammable gas, it automatically closes the main air supply valve quickly, cuts off the supply of gas, and timely stops the occurrence of a vicious accident.

2. It is connected with the limit temperature pressure safety controller of the thermal equipment. When the temperature of the detection point in the equipment exceeds the set limit value, the gas supply valve is automatically closed quickly to stop the supply of fuel.

3. Connected with the central fire alarm system of the high-rise building. When a fire occurs in the building, the gas supply in the building is automatically cut off to prevent the gas explosion.

4. It can be set in the gas supply pipe network of the city or factory, and can be centrally controlled in the central control room. The remote control can quickly close the pipeline supply gas at the accident site.
