Description

Technical Field

[0002] An explosion-proof solenoid valve encloses all the components that may ignite an explosive gas mixture of the equipment in a housing. The housing can withstand the internal explosion of the flammable mixture that penetrates into the interior of the housing through any joint surface or structural gap of the housing without being damaged, and will not cause the ignition of the external explosive environment formed by one or more gases or vapors. The components that may generate sparks, electric arcs, and dangerous temperatures are placed in the explosion-proof housing, and the explosion-proof housing separates the internal space of the equipment from the surrounding environment. There are gaps in the explosion-proof housing. Due to the breathing effect and gas penetration effect of the electrical equipment, there may be an explosive gas mixture inside.

[0003] When the explosion-proof solenoid valve is in use, when the rigidity of the pipeline installed on the explosion-proof solenoid valve is insufficient, the vibration generated during the operation of the explosion-proof solenoid valve will be transmitted to the pipeline, affecting the pipeline. Therefore, a resin-type explosion-proof solenoid valve is introduced according to the above-mentioned problems. Content of the Utility Model
