Electric starter for opening pressure difference type container valve

Abstract

The present invention is an electric starting device for opening a differential pressure container valve, which includes a shell, a percussion shaft, a knife cover, a poking knife, a percussion spring, a return spring, an electric drive mechanism, and a handle. The firing shaft is connected as a combination shaft by thread, and there is a firing spring at the end of the tool sleeve of the combination shaft. The main shaft of the electric drive mechanism is perpendicular to the combination shaft. Composed of insurance components, two clamps are placed vertically or horizontally to clamp the middle of the firing shaft. There is a double-headed cam under the firing shaft in the middle of the two clamps. The rotating shaft of the double-headed cam is connected to the main shaft of the electric drive mechanism. Electric drive The other end of the main shaft of the mechanism is equipped with a clutch, and a safety buckle is arranged between the clutch and the handle. The invention effectively prevents the abnormal starting of the electric starting device when being impacted by the environment through the double safety locking of the firing shaft, ensures the reliability of the automatic fire extinguishing system, and is applied in the field of fire protection.

Description

Technical field: [0001] The invention relates to an electric starting device for a gas storage bottle in an automatic gas fire extinguishing system for firefighting, in particular to an electric starting device for opening a differential pressure container valve, which is used in the field of firefighting. Background technique: [0002] At present, the known starting devices for opening differential pressure container valves in automatic gas fire extinguishing systems are mostly electromagnetic starting devices. The iron core moves in a straight line, and the iron core directly pushes the poking knife (or push rod) to puncture the sealing diaphragm or push the sealing valve core to open the container valve; the second is to use the electromagnet as a pilot valve to control a valve with The energy storage mechanism with greater energy uses the power of the solenoid valve core after power-on to start the release switch of the energy storage mechanism, and then the energy stora...

AI Technical Summary

Problems solved by technology

The above two forms of starting devices all have a common defect, that is: as long as there is an excitation along the axis of the iron core and a force sufficient to drive the iron core is generated, it is possible to move the poking knife (or push rod) And puncture the sealing diaphragm or push the valve core for sealing, release the medium in the container, and cause the whole system to malfunction
