Abstract
The utility model belongs to the fire-fighting life saving field relating to an inflation device of leaking stoppage gun which is suitable to be used for one person to fast fill the stopping leak gun with the gas and is sealed as the leaking equipment such as the oil tank car, the liquid storage tank and the liquid truck. The device is composed of a gas storage steel cylinder (1), a steel cylinder seat (2), a metallic diaphragm (3), an attachment plug (4), a puncturing needle (5), a locking nail (6), a one-way valve (7), a one-way valve connecting seat (8), a one-way valve core (9), a Y-type sealing ring (10), a circlip (11) and a screwdriver (12). When used, the metallic diaphragm (3) of the sealed gas storage steel cylinder (1) is punctured by the puncturing needle and the gas is released to realize the gas-filled goal.
Description
The utility model belongs to the fire-extinguishing and lifesaving field, relates to a kind of device to the plugging gun inflation.It is applicable to single fast to the plugging gun inflation, and the equipment of leakage takes place as fuel tank, liquid container, cistern wagon etc. in sealing.
Because the liquid that leaks, the position of leakage, the shape of leakage hole vary, therefore, the instrument of leak stopping also is diversified, and inflation sealing gun is exactly a kind of leak stoppage tool wherein.Its rifle head is the capsule of a sealing, and inflation can be expanded.When equipment has leakage, the rifle screw plug can be advanced in the Leak hole, charge into gas, after the rifle head dilatancy, block the leak of equipment.At present, this leak stoppage tool only has several families such as German Fei Teer company to produce abroad, and domestic also have only a family to produce.The inflator of this plugging gun is made up of foot pump, inflated hose, safety valve, one-way valve etc.When the plugging gun head need be inflated, firmly step on foot pump, air is given the inflation of plugging gun head by high pressure hose, one-way valve, and there is the low defective of charging efficiency in this inflator, wastes time on rescue and relief work need be seized every minute and second, and allows the condition of a disaster be doubled and redoubled easily.
The purpose of this utility model is to provide a kind of improved, can give the device of plugging gun head inflation fast, it can give plugging gun head gassy in the extremely short time, reach the purpose of leak stopping, can effectively prevent the leak stopping inefficiency that slowly causes because of inflating.
The purpose of this utility model be achieved in that with inflator use gas storage steel cylinder, steel cylinder seat instead, puncture pin, replacement such as attachment plug, rotor, one-way valve, pinning, check valve body, one-way valve connecting base, gas storage steel cylinder bottleneck is sealed by metal diaphragm, gas storage steel cylinder and steel cylinder seat weld together, attachment plug partly links together the steel cylinder part with one-way valve, attachment plug and steel cylinder seat are connected with the fixation of pinning by rotor with one-way valve by being threaded.Bottle opener is rotated to an angle, the jack-up pinning, attachment plug can be installed on the check valve body or pull down.Puncture pin and be installed in the attachment plug, both can slide relative.When puncturing needle movement, puncture metal diaphragm, gas overflows from the gas storage steel cylinder, by one-way valve, enters into the rifle head of plugging gun.
The utility model is compared with conventional art, has shortened inflationtime greatly, and the one man operation is safe, convenient, fast.
The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is the sectional drawing according to the plugging gun inflator that the utility model proposes
Below in conjunction with details and the working condition of description of drawings according to the concrete device that the utility model proposes.
This device by gas storage steel cylinder (1), steel cylinder seat (2), metal diaphragm (3), attachment plug (4), puncture pin (5), pinning (6), check valve body (7), one-way valve connecting base (8), one-way valve spool (9), y-shaped ring (10), circlip (11), bottle opener (12) etc. and form, A is a pressure gauge, and B is a plugging gun rifle head.
During work, fill in the gas storage steel cylinder (1) and store a certain amount of pressurized air or nitrogen, reach certain pressure (can see by pressure gauge A), attachment plug (4) and steel cylinder seat (2) are by being threaded togather.Rotate bottle opener (12), jack-up pinning (6), with attachment plug (4) and puncture pin (5) and insert in the one-way valve valve body (7), counter-rotating falls pinning (6) again, pins attachment plug (4) by the effect of pinning (6) and circlip (11), prevents to skid off.Be installed in the attachment plug (4) because of puncturing pin (5), can slide relative between the two, so when needing to give plugging gun head B inflation, promote gas storage steel cylinder (1) and steel cylinder seat (2) to the right with hand, attachment plug (4) moves right, make and puncture pin (5) and attachment plug (4) generation relative displacement, the metal diaphragm (3) of puncture through seal gas storage steel cylinder (1), simultaneously, the right-hand member that punctures pin (5) backs down the spool (9) of one-way valve, thereby make the interior pressurized air of gas storage steel cylinder because of pressure difference enters in the plugging gun head B by the center hole that punctures pin (5), make it dilatancy, seal up the crackle that leaks body.
When giving plugging gun head B inflation, the right-hand member of attachment plug (4) pins with pinning (6) and circlip (11), and attachment plug (4) and gas storage steel cylinder (1) and check valve body (7) are thrown off, and the front prevents gas leakage with y-shaped ring (10) axial seal.After plugging gun head B and gas storage steel cylinder (1) pressure reached balance, gas storage steel cylinder (1) can be extracted out from check valve body (7) with attachment plug (4), and because of check valve body (7) has one-way valve, so gas can be from plugging gun head B internal leakage, pressure remains unchanged; When extracting attachment plug (4) out, rotary rotor (12) several angle makes pinning (6) certain distance (leaving the shaft shoulder of attachment plug) of upspringing, and gets final product.Can not extract out yet, under the effect of y-shaped ring (10), make the pressure stability in the rifle head, guarantee long-time sealing without leakage.
Claims (5)
1, a kind of plugging gun inflator, by gas storage steel cylinder (1), steel cylinder seat (2), metal diaphragm (3), attachment plug (4), puncture pin (5), pinning (6), check valve body (7), one-way valve connecting base (8), one-way valve spool (9), y-shaped ring (10), circlip (11), bottle opener (12) etc. and form, the gas that it is characterized in that gas storage steel cylinder (1) is the metal diaphragm (3) that punctures gas storage steel cylinder (1) bottleneck by the slide relative that punctures pin (5) and attachment plug (4), and gas enters into plugging gun head B by nonreturn valve core (9).
