Abstract
The utility model discloses an air inflation device used for a gas pipeline choke ball. A three-direct pipe is formed by an air inlet pipe, an air inflation pipe and an exhaust pipe. An air inflation faucet, a first valve and a pressure regulator are arranged on the air inflation pipe. A second valve, a first exhaust faucet and a second exhaust faucet are arranged on the exhaust pipe. According to the air inflation device used for the gas pipeline choke ball, due to the fact that a safe working pressure of the pressure regulator is set, when pressure inside the choke ball rises to the working pressure, air can not enter any more and construction safety is ensured. After the construction is finished, the choke ball has the advantages of being fast in exhaust speed when being exhausted. Moreover, air inside the ball can be exhausted completely, so that the choke ball can be pulled out of the pipeline conveniently and construction time is shortened.
Description
Technical field
The utility model relates to a kind of gas pipeline choke ball inflator.
Background technique
In gas pipeline when repairing excavation, enter pipeline in order to prevent air, sets off an explosion, and must leave the combustion gas of certain pressure in the pipeline of repairing pipeline location.If do not process like this, construction finishes, must be with residual air in the nitrogen replacement pipeline, then with the operation of could ventilating of combustion gas displacement nitrogen, take time and effort.Due to the combustion gas that leaves certain pressure in pipeline, the necessary shutoff of the hole interior conduit that digs when rushing to repair prevents that combustion gas from entering in the hole; For preventing in pipeline that residual air boosts too highly, in pipeline, combustion gas also need be diffused decompression.
Choke ball use in the repairing of a kind of gas pipeline, comprises that rubber bladder reaches the air pipe that is communicated with rubber bladder, is provided with valve on air pipe, and the rubber bladder outside is coated with one deck cloth cover.When the accidents such as gas pipeline generation leakage need be rushed to repair, at first bore a pipe tap on the tube wall of pipeline, again choke ball is filled in pipeline by pipe tap, open valve, and inflate in rubber bladder by the pore on air pipe, rubber bladder is expanded and fill inner-walls of duct, thereby the combustion gas of upstream is blocked.But, if when inflating non-inflatable device to choke ball, because can not know the actual pressure in choke ball, or inflation pressure is wayward, easily choke ball is exploded; Nature is during exhaust, and in ball, the gas velocity of discharge is slow, and period of exhaust is long, and can not emptying, and the engineering time is long, and ball is interior, and residual spheroid is difficult when gas is arranged pulls out in pipeline.Therefore, how to realize safety inflated and the Quick air-discharge of choke ball, become the problem that needs solution.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of gas pipeline choke ball inflator, with safety inflated and the Quick air-discharge of realizing choke ball.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of gas pipeline choke ball inflator, it forms three-way pipe by suction tude, gas tube and outlet pipe; Be provided with charging air inlet, valve one and pressure governor on described gas tube; Be provided with valve two, exhaust nozzle one and exhaust nozzle two on described outlet pipe.
Preferably, described pressure governor is positioned at charging air inlet one end of gas tube.
By technique scheme, the gas pipeline choke ball inflator that the utility model provides, because pressure governor has been set safe working pressure, the choke ball internal pressure rises to just no longer air inlet after working pressure, has guaranteed construction safety; In addition, construct after end, have advantages of that exhaust velocity is fast to the choke ball exhaust time, and gas in the thorough emptying ball of energy, thereby conveniently choke ball is pulled out pipeline, shortened the engineering time.
Description of drawings
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, during the below will describe embodiment, the accompanying drawing of required use is done to introduce simply.
Fig. 1 is the schematic diagram that the disclosed gas pipeline choke ball of embodiment is used inflator.
Numeral in figure:
11. suction tude 12. charging air inlet 13. pressure governors
14. valve one 15. valve 2 16. exhaust nozzles one
17. exhaust nozzle 2 21. gas tube 22. outlet pipes
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.
According to Fig. 1, the gas pipeline choke ball inflator that the utility model provides, it forms three-way pipe by suction tude 11, gas tube 21 and outlet pipe 22; Be provided with charging air inlet 12, valve 1 and pressure governor 13 on gas tube 21, pressure governor 13 is positioned at charging air inlet 12 1 ends of gas tube 21; Be provided with valve 2 15, exhaust nozzle 1 and exhaust nozzle 2 17 on outlet pipe 22.
Can use the utility model to be used for safety inflated, the Quick air-discharge of choke ball.With reference to figure 1, when choke ball is inflated, the air pipe of choke ball is connected on the charging air inlet 12 of gas tube 21, and the working pressure of pressure governor 13 is set, throttle down 2 15 is opened valve 1, with inflator, choke ball is inflated, source of the gas can be with nitrogen bottle or air pump, just no longer air inlet when the choke ball internal air pressure rises to the working pressure that pressure governor 13 sets; With reference to figure 1, during to the choke ball exhaust, the air pipe of choke ball is connected on exhaust nozzle 1 throttle down 1, open valve 2 15, and open source of the gas, the gas of source of the gas enters suction tude 11, when then flowing out from exhaust nozzle 2 17, gas in choke ball can be drawn, the gas flow rate of suction tude 11 is faster, and bleed speed is faster, until till the gas emptying in choke ball.
The gas pipeline choke ball inflation safety device that the utility model provides, because pressure governor 13 has been set safe working pressure, the choke ball internal pressure rises to just no longer air inlet after working pressure, has guaranteed construction safety; In addition, construct after end, have advantages of that exhaust velocity is fast to the choke ball exhaust time, and the gas in the thorough emptying choke ball of energy, thereby conveniently choke ball is pulled out pipeline, shortened the engineering time.
Multiple modification to above-described embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.
