The technical scheme of the utility model is that:
the utility model provides an explosion-proof type electricity starts valve that drenches, includes drenches valve main part, solenoid valve, butterfly valve, pressure switch, the solenoid valve is explosion-proof type solenoid valve, the electrical control mechanism of butterfly valve is changed for mechanical locking means, pressure switch installs in explosion-proof power supply box, signal line and control line in the drenches valve main part all connect through explosion-proof pipe or explosion-proof box.
Preferably, the butterfly valve includes first butterfly valve and second butterfly valve, first butterfly valve and second butterfly valve are the normal open state, and it can guarantee to be the system water supply can arrive work the very first time to keep normally open to take place the conflagration.
Preferably, the solenoid valve is preceded by a filter, and the solenoid valve requires a high degree of cleanliness for the medium, thus requiring the fluid to be filtered.
Preferably, the pressure switch is a non-explosion-proof pressure switch, because the pressure switch is installed in an explosion-proof power supply box, the safety of the pressure switch is not required to be worried about, the pressure switch is not required to be replaced by the explosion-proof pressure switch, and the cost can be saved.
Particularly, the utility model has the advantages of it is following:
the electromagnetic valve is an explosion-proof electromagnetic valve, has the explosion-proof function of bearing the explosion pressure of gas, has the blocking function on the energy transfer of gas explosion, and is suitable for transmitting flammable and explosive media or special electromagnetic valves specially used in explosive dangerous places.
The electric control mechanism of the butterfly valve is replaced by a mechanical locking device, so that the damage of electric sparks in the working process of the butterfly valve can be avoided.
The pressure switch is arranged in the explosion-proof power box, so that the pressure switch can be prevented from being exploded to influence the work.
The signal line and the control line in the deluge valve main part all connect through explosion-proof pipe or explosion-proof box, and explosion-proof pipe or explosion-proof box are applied to the interface of circuit, and under the explosion gas environment, even have the circuit spark to appear in the box, perhaps also permeated some explosive gas in the box, appear the detonation of miniwatt under the spark effect, and the box can stand this kind of condition, can not be because the box is insecure, breaks, reveals the flare to the environment, arouses the explosion of big environment.
To sum up, compare with prior art, the utility model provides a pair of explosion-proof type electricity starts drenches valve, drenches the valve through the electricity start-up to current and reforms transform, can reach corresponding explosion-proof grade, ensures that the electricity starts to drench the valve and satisfy explosion danger area explosion-proof requirement.
