Description
Technical field
The utility model relates to a kind of control valve for switch cubicle fire extinguisher.
Background technique
No matter be domestic at present, or the switch cubicle of import, major part does not all configure fire-extinguishing installation, is all to rely on behind relay protection tripping circuit breaker excision fault point, by manually putting out a fire.Although at present the judgement time (20-30ms) of protection, the trip time (40-60ms) of circuit breaker have shortened widely, the fire phenomena that switch cubicle causes due to short trouble or many existence.Existing part blasting type fire extinguisher be by packing explosive in foaming agent, when fire burns on initiator and temperature reaches 800 degree when above, can ignition charge bag ejection foam fire-fighting, and foaming agent can not be used for the fire extinguishing in high-tension switch cabinet.Even if indivedual switch cubicles are provided with fire extinguisher, they are controlled and are started fire extinguishing by solenoid valve.Electromagnetic valve exists the reaction time long, can not put out in time the problem of flare, can burn switch cubicle.
Model utility content
The utility model proposes a kind of control valve for switch cubicle fire extinguisher, the fire-fighting equipment control valve used that has solved existing switch cubicle can not start fire extinguisher in time puts out the flare of generation.
The technical solution of the utility model is achieved in that
For a control valve for switch cubicle fire extinguisher, comprise valve gap, valve body and piston rod, between described piston rod part and described valve gap, form relative airtight space, in described relatively airtight space, be placed with the explosive cartridge that contains trace explosive; On described valve gap, be also provided with for lead-in wire through aperture; Described piston rod is also provided with draw-in groove, on described valve body madial wall, is also provided with the clamping close device coordinating with draw-in groove, and described valve body bottom is the bottom that is provided with opening.This control valve is the control valve that uses blasting technique principle to develop.
Further, the position in the middle of described valve gap inwall is positioned at arranges storage space, and described storage space is for explosive bag.
Further, described clamping close device is end cap, described end cap comprises plug cover, be positioned at plug cover plug, be positioned at plug and overlap and be positioned at the spring below plug.
Further, described piston rod is "T"-shaped piston rod.
Further, valve body madial wall between transverse end and the clamping close device of described "T"-shaped piston rod part is provided with round platform, the through hole passing for "T"-shaped piston rod is set in the middle of described round platform, and the slightly larger in diameter of described through hole is in the diameter of "T"-shaped piston rod vertical end; The object that described round platform is set is to ensure that "T"-shaped piston rod moves downward rear described clamping close device and can snap in draw-in groove.
Further, described piston rod bottom is provided with jacking block, and the diameter of described jacking block is greater than the diameter of piston rod, and the valve openings of described fire extinguisher adapts.The object that described jacking block is set is that the material that prevents fire extinguisher ejection enters in described control valve.
Further, the bottom of described valve body is provided with removable stop, and in the time that described control valve is not arranged on fire extinguisher, described block is used for preventing that piston rod from gliding.
Relative confined space described in the utility model refers to and complete confined space comparison, the space forming between described piston rod part and described valve gap is not completely airtight, this is because piston rod needs down sliding after detonation of a cartridge, therefore and between described valve gap inwall has small gap.
The beneficial effects of the utility model are that described control valve uses blasting technique principle to develop, the explosive cartridge that contains trace explosive is placed in control valve, receive the instruction of self-controller, open fast control valve in 1ms, the valve of pushing powder-type fire extinguisher open carries out directional fire-extinguishing.Like this, short circuit accident fault point and arclight cause the fire forming, and are precisely put out very soon, and burnt area is little, burning is few, can restore electricity quickly and easily.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
See figures.1.and.2, control valve described in the utility model comprises that valve gap 1, valve body 2 can be also other piston rods well known to those skilled in the art with "T"-shaped piston rod 5(), valve gap 1 is provided with for lead-in wire 4 apertures that pass 3; Valve gap 1 below is provided with "T"-shaped piston rod 5, the transverse ends of "T"-shaped piston rod 5 and valve body 2 madial wall close contacts, and between valve gap 1, form relative confined space; Relatively in confined space, the explosive cartridge 6 that contains trace explosive is installed; Certainly explosive cartridge 6 also can be placed on the storage space 7 of the position of valve gap 1 inwall in the middle of being positioned at, and the energy comparison stepless action of explosive charge generation is on "T"-shaped piston rod 5 like this."T"-shaped piston rod 5 vertical end one end contrary with valve gap 1 is provided with jacking block 13, and the material that jacking block 13 can block fire extinguisher ejection enters control valve inside; "T"-shaped piston rod 5 vertical positions also arrange draw-in groove 11, on relative two madial walls of valve body 2, clamping close device are installed, and described clamping close device matches with described draw-in groove 11.Described clamping close device is end cap in the present embodiment, and end cap comprises plug cover 8, be positioned at the plug 9 of plug cover 8, be positioned at plug cover 8 and be positioned at the spring of plug 9 belows.Relative two madial walls of valve body 2 between transverse end and the end cap of "T"-shaped piston rod 5 are provided with round platform 12, and the through hole passing through for "T"-shaped piston rod 5 vertical end is set in the middle of round platform 12; When explosive cartridge 6 explosion times, stressed the moving downward of "T"-shaped piston rod 5, round platform 12 is for after ensureing that "T"-shaped piston rod 5 moves downward, plug 9 can snap in draw-in groove 11.In the time that control valve is not arranged on fire extinguisher, the bottom of valve body 2 is also provided with block 14(referring to Fig. 3), for blocking "T"-shaped piston rod 5.The "T"-shaped piston rod 5 of control valve is positioned at fire extinguisher top, and corresponding with the valve mandril position of fire extinguisher.
Working principle of the present utility model:
Control valve receives that after the action command that controller sends, the explosive cartridge 6 that contains trace explosive is blown, and the shock wave of generation promotes "T"-shaped piston rod 5 and backs down extinguisher valve push rod downwards, and fire extinguisher is put out a fire; Simultaneously spring 10 heads into plug 9 in the draw-in groove 11 of "T"-shaped piston rod 5, makes the "T"-shaped piston rod 5 cannot resilience, thereby makes extinguisher valve remain open mode.This control valve judges rear startup according to short circuit current and arclight dual signal, instead of restarts after by the time burning, and reliability is high, and speed is fast, and is reinstalling after explosive cartridge 6, can Reusability.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
