In the inside third stepped hole 107 of nut 10；Ball 701 is put into locking hole 104 again and enters second step hole 106 for electricity initiation
After two conducting wires of device conducting wire 20 separate, ball 701 is locked to lock-screw 702 and fixed electric initiator conducting wire 20 two
Conducting wire；Then sealant 60 is sealed up into gas generating agent 50 and electric initiator 30 from the filling of the upper end step hole 105 of valve nut 10；Most
Spool 3 is put into valve body 1 afterwards, installs gasket (not shown), electric drive valve valve head 1 is installed to by valve body by valve nut 10
Thread locking adhesive sealing is played on 2, at connection screw thread.
Electric drive valve starting pinciple of the present invention: fire extinguishing system is powered after receiving enabling signal to electric initiator 30, after energization
Electric 30 reflecting point of initiator is quick-fried on fire, lights gas generating agent 50, and the reaction of gas generating agent 50 generates expanding gas, where electric drive 30
The type chamber pressure moment of 10 inside third stepped hole 107 of valve nut increases, and forms immense pressure and pushes spool 3, compresses spool 3
Valve body 2 is pierced out after spring, is provided the sealing diaphragm in enough pierce force puncture bottle valves or selector channel to spool 3 and (is not schemed
Show), the extinguishing chemical in fire-extinguishing bottle (not shown) sprays, and puts out a fire to kindling point.
The valve nut 10 of electric drive valve through the invention is by the fixed locking of electric initiator 30, and in energization, electricity causes
After device 30 lights pre-buried gas generating agent 50, the gas-powered spool 3 of generation is released, and is realized driving fire-fighting bottle valve (not shown) or is selected
The effects of selecting channel (not shown), is widely used in the starting of fire-fighting fire extinguishing gas and the selection in channel.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
