Description
Technical field
The utility model relates to the technical field of valve, specifically is a kind of bottle valve for fire-fighting equipment.
Background technique
The bottle valve that is used for fire-fighting equipment of prior art, as depicted in figs. 1 and 2, it generally includes valve body 07, piston assembly, switch block 015, security component 016, pressure cap 01 and driven unit 014; Have the suction port 08 and the air outlet 09 that are connected in the valve body 07, piston assembly is slidingly fitted in the valve body 07 and forms valve between suction port 08 and air outlet 09, switch block 015 and security component 016 are connected on the sidewall of valve body 07, also have on the sidewall of valve body 07 for the mounting hole 017 that connects inflator, the upper end of valve body 07 connects pressure cap 01, driven unit 014 is connected with pressure cap 01, and pressure cap 01 is threaded in the upper end of valve body 07; Piston assembly comprises piston 02, piston rod 03, trim ring 04, seal ring 05 and flow guiding nut 06, the upper end of piston rod 03 and piston 02 are integrated, the lower end is connected with flow guiding nut 06 and forms valve by trim ring 04 and seal ring 05 with valve body 07, and piston 02 is slidingly fitted in the valve body 07; Be connected with top cutter 012 in the driving mechanism 014, piston 02 top is connected with the diaphragm 010 of releasing by hexagon socket head cap screw 011, and the point of a knife of top cutter 012 is positioned at the top of the diaphragm 010 of releasing, and has gas storage chamber 013 between piston 02 and the pressure cap 01.
More than the working principle of this bottle valve be: when being filled with gas in the gas cylinder, first in inflator mounting hole 017, install inflator, left-handed switch block 015 again, make gas enter suction port 08 by the gas channel in the valve body 07, at this moment, fire-suppressant gas with certain pressure is filled with from inflator, enters gas cylinder and stores; Inflate complete after, dextrorotation switch block 015 is with valve closing; At this moment, jack-up upwards under the pressure-acting of piston 02 gas in spring and gas cylinder drives coupled trim ring 04, seal ring 05 and flow guiding nut 06 and moves on together, makes seal ring 05 block valve, and valve cuts out.When breaking out of fire, after driving mechanism 014 is received the order of system, with top cutter 012 to pressing down, top cutter 012 punctures the diaphragm 010 of releasing, pressurized gas just rise to from the endoporus of piston rod 03 in the gas storage chamber 013, when gas storage chamber 013 is interior assembled certain pressure after, force piston 02 to move down, band dynamic seal ring 05 breaks away from valve, and this moment, fire-suppressant gas just can spray the air outlet 09 from valve body 07.
But the cylinder valve of above-mentioned this structure exists following shortcoming to be:
1) piston and piston rod are as a whole, and wherein the endoporus of piston rod is elongated hole, and this Small and Deep Hole Machining difficulty slightly has deviation to scrap, and therefore greatly increases cost of production;
2) top cutter, the diaphragm of releasing, hexagon socket head cap screw and spring etc., many, the complex structure of part, thereby the drawback when bringing assembly fee have been related in the driving mechanism;

4) in addition, the diaphragm of releasing is normally made by metal body, and its sealing is poor, and leakage point is more, can cause a small amount of gas leak phenomenon, affects the normal use of gas cylinder.
The model utility content
Technical problem to be solved in the utility model is, provide a kind of simple in structure, easy to process, need not change the diaphragm of releasing with regard to reusable bottle valve for fire-fighting equipment.
For solving the problems of the technologies described above, the bottle valve that is used for fire-fighting equipment that the utility model provides, comprise valve body, pressure cap, piston assembly, switch block, security component and driving mechanism, have the suction port and the air outlet that are connected in the described valve body, piston assembly is slidingly fitted in the valve body and forms valve between suction port and air outlet, switch block and security component are connected on the sidewall of valve body, also have on the sidewall of valve body for the inflator mounting hole that connects inflator, pressure cap is connected to the upper end of valve body, driving mechanism is connected on the pressure cap, has gas storage chamber between piston assembly and the pressure cap, described driving mechanism is gas actuating device, have on the pressure cap for the gas actuating device mounting hole that connects gas actuating device, this gas actuating device mounting hole communicates with gas storage chamber.
Described piston assembly comprises piston, piston rod, spring, trim ring, seal ring and flow guiding nut; Described piston is slidingly fitted in the valve body, and an end and the piston of spring push against, and the other end and valve body push against; The upper end of described piston rod is connected with piston dismountable, and the lower end is connected with flow guiding nut, and by trim ring and seal ring and valve body formation valve, this place's valve is between the suction port and air outlet of valve body.
After adopting above structure, the utility model compared with prior art has the following advantages:
1) owing to cancelled the interior elongated hole of piston rod, cancelled the structure of utilizing the lancination broken diaphragm of releasing in top to discharge gas, utilize gas actuating device to press down the structure that piston is opened valve release fire-suppressant gas and use instead, greatly simplified the structure of drive unit, process also convenient;
2) owing to change piston and piston rod into can make up structure, process conveniently, assemble also convenient;
3) in addition, after once using gas cylinder, when again being filled with fire-suppressant gas in the gas cylinder, needn't remove drive unit, needn't change the diaphragm of releasing, therefore, save the time, provided cost savings;
4) in addition, cancelled the diaphragm of releasing that metal body makes after, good airproof performance can reduce the leakage of gas, thereby guarantees the normal use of gas cylinder.
