Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but structure of the present invention is not limited only to following examples:
[embodiment]
As Fig. 1, shown in Fig. 2, for the high sealing linkage structure of bleeding device and gas pipeline, comprise the bypass duct 1 that connects gas pipeline and the mounting head 2 that is connected bleeding device, described mounting head 2 comprises connecting tube 201, the stage casing of connecting tube 201 is provided with an annular protrusion 202, on connecting tube 201, also cover has a threaded pipe 203, the external diameter of threaded pipe 203 is greater than the external diameter of annular protrusion 202, wherein one end of threaded pipe 203 is provided with catch ring 204, the internal diameter of catch ring 204 is consistent with the external diameter of connecting tube 201, the both sides of annular protrusion 202 are respectively arranged with a rubber ring 205, the external diameter of connecting tube 201 coordinates with the internal diameter of bypass duct 1, connecting tube 201 injects bypass duct 1, until stopped by annular protrusion 202, in bypass duct 1, be provided with the outside thread coordinating with threaded pipe 203, in bypass duct 1, be provided with one around the bypass duct barrier plate of 1 one weeks 3, barrier plate 3 is provided with rubber sleeve 4 towards a side of mounting head 2, described barrier plate 3 is provided with a groove A301 towards a side of mounting head 2, groove A301 coordinates with rubber sleeve 4, rubber sleeve 4 is stuck in groove A301, and there is part to expose groove A301, the both sides of described catch ring 204 arrange respectively groove B206 and groove C207, groove B206 and groove C207 coordinate with rubber ring 205, two rubber rings 205 are stuck in groove B206 and groove C207, and rubber ring 205 also has part to expose.General one section of gas pipeline 10 always leaves the arm 8 that connects bleeding device, a valve 9 is set on arm 8, this device is connected on gas pipeline 10 by connecting head 2, in connecting head 2, connecting tube 201 coordinates with arm 8, connecting tube 201 can be inserted in arm 8, on arm 8 outer walls, be provided with the outside thread with threaded pipe 203 screw-internal thread fit, threaded pipe 203 is enclosed within on arm 201, catch ring 204 is near diffuse channel 1, so threaded pipe 203 is threaded after arm 8, can be blocked ring 204, 202 two cooperations of annular protrusion stop, but catch ring 204 can be oppressed annular protrusion 202, oppress two rubber rings 205, ensure sealing, after diffuse channel 1 connects, open the valve 9 on arm 8, and open the switch valve 6 on diffuse channel 1, when beginning, slowly put combustion gas by pressure regulator valve 5, in burning head 3 places igniting, combustion gas, in burning, regulate velocity of combustion by pressure regulator valve 5, it is not only control combustion speed that pressure regulator valve 5 is set, also while preventing from lighting a fire, suddenly the excessive flame of emerging, hurt staff, this device has an aerator 7, 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 6, open aerator 7, 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 5, 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, flame trap 4 is compared with switch valve 6 and the more close burning head 3 of pressure regulator valve 5, mainly to prevent that flame is burned in gas pipeline by pipeline, also protection is to switch valve 6 and pressure regulator valve 5, flame trap 4 is very existing devices.Existing bleeding device, in use, after burning head 3 place's fuel gas buring overlong time, can conduct heat to flame trap 4, flame trap 4 is metals that have a lot of vents, combustion gas is through vent transmission, when flame passes through vent, because what cut apart is too little, temperature reduces too large, cause flame extinction, so flame trap 4 is to control temperature to stop travel of flame, when after flame trap 4 heatings, may lose back-fire relief effect, this device arranges a cooling pipe 801 between flame trap 4 and burning head 3, cooling pipe 801 wraps up diffuse channel 1, 801 li of cooling pipes constantly have cold water to flow through, be water pump 805 and condenser 806 results of the joint efforts, carry out cooling to the diffuse channel 1 near flame trap 4, prevent that heat is delivered to flame trap 4, fire damper 802 is set again, stop that the flame at burning head place is blowed to flame trap by strong wind, further ensure the back-fire relief effect of flame trap 4.And in this device, rubber sleeve (4) is stuck in groove A301, there is part to be exposed, make threaded pipe 203 and the barrier plate 3 that are exposed on the external can be oppressed, play sealing, is to prevent in threaded pipe 203 rotations in groove A301, rubber sleeve 301 is collapsed out diametrically, have influence on sealing; And the effect of groove B206 and groove C207 is also as groove A, plays the effect of firm rubber ring 205, has ensured sealability.
In the present embodiment, aerator 7 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 diffuse after adopting aerating as far as possible.
In the present embodiment, burning head 3 places are provided with an ignition 8, and staff can be far from burning head, control ignition sparking, have protected staff.
In the present embodiment, catch ring 204 is connected with threaded pipe 203 is integrated; Annular protrusion 202 is connected with connecting tube 201 is integrated, has ensured join strength, be not easy to damage, and sealability is also best.
In the present embodiment, burning head 3 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.
