Five types and specifications explosion-proof solenoid valve coil

The characteristics of explosion-proof solenoid valve 

(1) The external leakage is blocked, the internal leakage is easy to control, and the use is safe. 

(2) The system is simple, easy to connect the computer, low price. 

(3) Fast action, small strength, light modeling. 

(4) The adjustment accuracy is limited, and the applicable medium is limited. 

(5) A variety of models, wide range of uses. 

Advantages of explosion-proof solenoid valve 

1, explosion-proof solenoid valvelong service life. 

2, explosion-proof solenoid valve working system: long-term working system, repeated short-time working system and short-time working system. Explosion-proof solenoid valves are long-term working system, which allows the coil to work for a long time. For a long time to open the valve and a short time to close the situation, it is appropriate to choose normally open solenoid valve. For short time working system, large batch, can be special order, reduce power consumption. 

3, explosion-proof solenoid valve working frequency: when the working frequency requirements are high, the structure is the best direct acting solenoid valve, the power supply is the best alternating current. 

Explosion-proof class of explosion-proof solenoid valve 

Class ia explosion-proof solenoid valve 

Electrical equipment that cannot ignite explosive gas mixtures during normal operation, first fault and second fault. 

In normal operation, the safety factor is 2.0; 

In case of failure, the safety factor is 1.5; 

When there are two failures, the safety factor is 1.0. 

Note: Contact with sparks must be equipped with flameproof housing, airtight housing or double safety factor.

ib explosion-proof solenoid valve 

Electrical equipment that cannot ignite explosive gas mixtures during normal operation and failure. 

In normal operation, the safety factor is 2.0; 

When a fault occurs, the safety factor is 1.5. 

During normal operation, contact sparks must be protected by flameproof shell or closed shell, and have self-display measures of failure, failure safety
