Abstract
The utility model relates to a safety fire-proof device for a medical hydrogen-oxygen filling and sealing machine. A hydrogen-oxygen fuel inlet pipeline and at least a hydrogen-oxygen fuel output mouth are fixed on a casing, a fire insulation valve is arranged between the hydrogen-oxygen fuel inlet pipeline and the output mouth and is composed of a barrel body and ventilating sheets arranged in the barrel body, at least one of ventilating sheets are made of metal sand grains through die casting, and a connecting space is arranged between the fire insulation valve and the hydrogen-oxygen fuel output mouth to compose a fire insulation chamber. The utility model has simple structure, high fire isolating rate and good safety.
Description
The utility model relates to the safe fire retardant device of a kind of pharmaceutical sector with the hydrogen-oxygen filling and sealing machine.
At present, pharmaceutical sector is string one a dry type fire insulation valve on the output pipe of the hydrogen or oxygen gas that generator for hydrogen or oxygen source produces with hydrogen-oxygen filling and sealing machine fire retardant device, and link to each other with filling and sealing machine, tempering phenomenon takes place when being used for preventing oxyhydrogen combustion, but the dry type fire insulation valve exists shortcoming, when the hydrogen or oxygen gas of output has moisture content, dry type fire insulation valve inner seal ring is soaked, and the back-fire relief effect that will not recur of dry type fire insulation valve is if at this moment tempering takes place, pipeline will be blown up, so,, must in time change fire insulation valve if seal ring is soaked, so not only cumbersome, and influence manufacturing efficiency.In addition, the cost height is unsuitable for pharmaceutical sector hydrogen-oxygen filling and sealing machine and uses.
The purpose of this utility model is to improve the deficiency of prior art and a kind of hydrogen-oxygen filling and sealing machine safety fire retardant device that is used for pharmaceutical sector is provided, and once mounting can be used for a long time, and back-fire relief is effective, guarantees that the hydrogen-oxygen filling and sealing machine moves with security and stability.
The technical solution of the utility model is, on a housing, being fixed with a hydrogen-oxygen fuel admission line chews with at least one hydrogen-oxygen fuel output, between hydrogen-oxygen fuel admission line and output are chewed, be provided with fire insulation valve, described fire insulation valve is to be made of with the ventail that metallic grit is cast into a cylindrical shell and a slice at least of putting within it, is provided with connection space formation back-fire relief chamber between fire insulation valve and hydrogen-oxygen fuel output are chewed.In case tempering takes place, fire retarding sheet goes out the fire resistance indoor in back-fire relief in the use, guarantees that medical hydrogen-oxygen filling and sealing machine safety normally moves.
The utility model is simple in structure, easy for installation, processing ease, fire retardant rate height, Safety performance are good.
Quoting embodiment below is described below by accompanying drawing:
Fig. 1 is the utility model structural representation
Fig. 2 is the fire insulation valve structural drawing
Embodiment:
On the shell 1 of a cuboid, be provided with hydrogen-oxygen fuel air inlet pipe plug 2, it is by on the nut 3 fixing hydrogen-oxygen supply lines 4 in the enclosure, hydrogen-oxygen supply line 4 communicates with three hydrogen-oxygen fuel burning holes 5, on its pipeline that communicates, be provided with a fire insulation valve, it is made up of a cylindrical shell 6 and storing 6 layers of ventilative fire retarding sheet 7 that is cast into the stainless steel sand grains within it, and the space between fire insulation valve and burning hole constitutes back-fire relief chamber 8.As oxyhydrogen combustion in a single day tempering takes place, fire retarding sheet will go out tempering resistance indoorly in back-fire relief layer by layer, avoid causing danger.Be fixed with axle 9 on the shell of this device in addition, in order to this device is linked to each other with generator for hydrogen or oxygen source.
Claims (2)
