Description
Technical field
The utility model relates to diffusing of natural gas transmission pipeline, particularly relates to a kind of gas pipeline bleeding device.
Background technique
In natural gas transmission, before a segment pipe is safeguarded, need to diffuse processing to pipeline, even because after the valve closing of pipeline both sides, in pipeline, also has combustion gas, directly safeguard, these combustion gas meetings are revealed, befouling environment, so generally first diffuse processing, and then safeguard, exhaust stack is connected to this segment pipe, derive the combustion gas processing of burning, because the pressure of combustion gas is larger in this pipeline, so meeting automatic flowing is to exhaust stack place, but be burned to last, always residual certain combustion gas in pipeline, cannot be burned to, although can not have a significant impact, but after revealing, maintained personnel breathe after suction, attendant's health is caused to very large impact.
Model utility content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, and a kind of gas pipeline bleeding device is provided, and solving existing bleeding device cannot all diffuse out all combustion gas in pipeline, the defect after leakage, attendant's health being impacted.
The utility model is achieved through the following technical solutions: gas pipeline bleeding device, comprise diffuse channel, diffuse channel one end is connecting head, the other end is burning head, described connecting head comprises the connecting tube that is communicated with diffuse channel, the stage casing of connecting tube is provided with an annular protrusion, on connecting tube, also cover has a threaded pipe, the external diameter of threaded pipe is greater than the external diameter of annular protrusion, wherein one end of threaded pipe is provided with catch ring, the internal diameter of catch ring is consistent with the external diameter of connecting tube, the both sides of annular protrusion are respectively arranged with a rubber ring, in described diffuse channel, be provided with flame trap, pressure regulator valve and switch valve, position near connecting head on diffuse channel is also connected with an aerator.A general segment pipe always leaves the arm that connects bleeding device, a valve is set on arm, this device is connected on gas pipeline by connecting head, in connecting head, connecting tube coordinates with arm, connecting tube can be inserted in arm, on arm outer wall, be provided with the outside thread with threaded pipe screw-internal thread fit, threaded tube is on arm, catch ring is near diffuse channel, so threaded pipe is threaded after arm, can be blocked ring, two cooperations of annular protrusion stop, but catch ring can be oppressed annular protrusion, oppress two rubber rings, ensure sealing, after diffuse channel connects, open the valve on arm, and open the switch valve on diffuse channel, when beginning, slowly put combustion gas by pressure regulator valve, light a fire at burning head place, combustion gas, in burning, regulate velocity of combustion by pressure regulator valve, it is not only control combustion speed that pressure regulator valve is set, also while preventing from lighting a fire, suddenly the excessive flame of emerging, hurt staff, this device has an aerator, mainly to be afraid of giving out of gas not exclusively in gas pipeline, when burning head does not have after flame, closing switch valve, open aerator, in gas pipeline, add air, after air and combustion gas mixing, make the gas pressure intensity in gas pipeline again become large, and then once diffuse, because combustion gas is few, so regulate pressure regulator valve, make the speed of giving vent to anger want fast, just can burn, after repeatedly diffusing, can make the combustion gas in gas pipeline become as far as possible few, protect that staff's is healthy.
Further, above-mentioned aerator is air pump, air pump not only can be to aerating in gas pipeline in fact, can also carry out air-breathing, can be by remaining combustion gas sucking-off, but, although after carrying out once diffusing, ducted combustion gas has been lacked a lot, but for free from environmental pollution, repeatedly diffuses after adopting aerating as far as possible.
Further, above-mentioned burning head place is provided with an ignition, and staff can be far from burning head, controls ignition sparking, has protected staff.
Further, above-mentioned catch ring is connected with threaded pipe is integrated; Annular protrusion is connected with connecting tube is integrated, has ensured join strength, be not easy to damage, and sealability is also best.
Further, above-mentioned burning head is the tube head that is covered with through hole on a tube wall, and through hole is mainly conveniently to enter oxygen, convenient burning.
The beneficial effects of the utility model are: this device arranges aerator, after having diffused for the first time, in gas pipeline, add air, after air and combustion gas mixing, gas pressure intensity in gas pipeline is become greatly again, and then once diffuse, after repeatedly diffusing, can make combustion gas in gas pipeline become as far as possible few, protect that staff's is healthy; The connecting head of this device is easy to connect, good seal performance.
