Explosion-proof solenoid valve reliable performance is how strong

The coil shell of the explosion-proof solenoid valve not only has the flameproof effect of accepting the gas explosion pressure, but also has the blocking effect on the gas explosion energy transfer, with higher performance. Is specially planned for the transmission of flammable and explosive media or dedicated to explosive risk places of special solenoid valve series products, different environment and fluid should select different explosion-proof levels of solenoid valve.

Reliability:

1. Working life, which is not included in the ex-factory experiment project, belongs to the type experiment project. To ensure quality should choose regular manufacturers of brand products.

2. Operation system: divided into long-term operation system, repeated short-time operation system and short-time operation system. The company's conventional products are long-term operation system, coil promised long-term electrification operation. For long term valve open as long as the short time closed, it is appropriate to choose normally open solenoid valve. It can be specially ordered to reduce power consumption when the operation is short and the batch is large.

3, operation frequency: when the frequency of action is high, the structure should be preferred direct acting solenoid valve, the power supply is preferred AC.

4, the action is firm, strictly speaking, this experiment is not formally listed in our country electromagnetic valve professional specification, in order to ensure the quality of regular manufacturers of brand products should be selected. Some occasions the number of action is not much, but the requirement of reliability is very high, such as fire protection, emergency protection, must not be careless. Especially important, should also take two use double insurance.
