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

Embodiment Construction

[0012] According to accompanying drawing 2, poking knife 15 or push rod (not shown in the figure), knife cover 14, percussion shaft 1 just become combined shaft by threaded connection, and percussion spring 5 is arranged between combined shaft and housing 2, A pair of insurance components composed of clamping plate 4, return spring 3 and clamping plate shaft 13 are also housed in the housing 2. There is a double-headed cam 6 under the firing shaft in the middle of the two clamping plates 4, and the rotating shaft of the double-headed cam 6 is connected to the electric power. The main shaft of driving mechanism 7 links to each other, and clutch 9 is housed on the other end of the main shaft of electric driving mechanism 8, and safety buckle 11 is arranged between clutch 9 and handle 10 to guarantee that clutch 9 and handle 10 do not engage at ordinary times, when pulling safety buckle 11, Push the handle clutch 9 and the handle 10 to engage. When power is applied to the electri...

Abstract

The electric starter for opening pressure difference type container valve includes casing, triggering shaft, knife pouch, pricking knife, triggering spring, repositioning spring, electric drive mechanism and handle. Inside the casing, the pricking knife, the knife pouch and the triggering shaft are connected through screws to form a combined shaft; the triggering spring is in the tail of the combined shaft; and the electric drive mechanism has main shaft perpendicular to the combined shaft. The electric starter features the safety assembly comprising two clamping boards, the repositioning spring and clamping board shafts; one double-head cam with rotation shaft connected to the main shaft of the electric drive mechanism; one clutch mounted onto the other end of the main shaft of the electric drive mechanism and one safety buckle set between the clutch and the handle. The present invention is used in automatic fire extinguishing system and has double locking to the triggering shaft and raised reliability.

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...
