Abstract
The utility model discloses a gas pipeline flame arrester, including having the body of inner chamber, this body one end is equipped with the interface of giving vent to anger, and this body other end is equipped with the end cover, be equipped with on the body lateral wall with the interface that admits air of gas pipe connection, lie in the region of admitting air the interface and giving vent to anger between the interface in the body and be equipped with the back -fire relief core, be equipped with the through -hole on this back -fire relief core, flexible cushion is installed through the elastic component is fixed to the interface inner wall that admits air, this elasticity cushion lies in below the interface that admits air to the area that the area of this elasticity cushion is greater than coherent mouthful. The utility model discloses the back -fire relief performance is good, can in time cut off the gas supply of gas supply line moreover, and is effectively explosion -proof.
Description
Technical field
The utility model relates to a kind of spark arrester, specifically a kind of spark arrester being mainly used in gas pipeline.
Background technology
At present, gas supply has become a requisite part in people's daily life, and fuel gas supply conduit, also be urban construction, community, the development trend of office space, recently, because combustion gas using method mistake, and cause gas kitchen ranges, the accident of gas meter, flow meter blast happens occasionally, cause casualties, combustion gas is caught fire in pipeline or equipment, flame can spread very soon, cause a large amount of Vigorous gas combustion explosion, cause fire, thus, usually in flammable explosive gas pipeline, spark arrester is installed, play the equipment preventing from external flame from scurrying into having flammable explosive gas, pipeline or prevention flame are at equipment, the effect that pipeline enclosure spreads, at present, though simple structures such as traditional wire fabric arresters, but Fire resistances is not good enough, and although more new-type corrugated plate dst spark arrester Fire resistances is better, complex structure, in addition, traditional gas pipeline fire arrester only has back-fire relief function, and it directly can not cut off gas supply, and thus, under the condition that operate miss or other hardware facilities damage, effectively can not prevent gas explosion, its safety coefficient is very low, owing to containing impurity in combustion gas, after long-term use, its inside may block spark arrester, causes air feed smooth, thus affects result of use.Therefore, for solving the problems of the technologies described above, be necessary to provide that a kind of structure is simple, safe and reliable, explosion-proof performance is good, do not affect the spark arrester of result of use.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of gas pipeline fire arrester, and Fire resistances is good, can cut off the gas supply of steam line in time, effectively explosion-proof.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme:
A kind of gas pipeline fire arrester, comprise the body with inner chamber, this body one end is provided with interface of giving vent to anger, this body other end is provided with end cap, and tube wall is provided with the intake interface be connected with gas pipeline, is provided with fire-retardant core in body at intake interface and the region of giving vent to anger between interface, this fire-retardant core is provided with through hole, described intake interface inwall is fixedly equiped with elastic rubber fitting by elastic component, and this elastic rubber fitting is positioned at below intake interface, and the area of this elastic rubber fitting is greater than the area connecing gas port.
Be positioned at intake interface lower end in described housing and be provided with step position, elastic rubber fitting is under pressure and is stuck in this step position when rising and blocks intake interface.
Be provided with the safety net be made up of thermoplastic in described intake interface, this safety net is provided with air-vent.
Through hole on described fire-retardant core is less than the diameter of the port towards interface of giving vent to anger towards the diameter of the port in intake interface direction.
The through hole of described spark arrester is horn-like.
The outer wall of described interface of giving vent to anger is provided with slot.
The outer wall of described interface of giving vent to anger is provided with screw thread.
The utility model Fire resistances is good, once burn, the gas supply of gas pipeline can be cut off in time, avoid the gas supply continued, and then the burning of combustion gas is solved from root, effectively prevent the blast because too much combustion gas produces at confined space vigorous combustion.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model cross-sectional view.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, a kind of gas pipeline fire arrester, comprise the body 7 with inner chamber, this body 7 one end is provided with interface 9 of giving vent to anger, this body 7 other end is provided with end cap 1, body 7 sidewall is provided with the intake interface 5 be connected with gas pipeline, fire-retardant core 6 is provided with at intake interface 5 and the region of giving vent to anger between interface 9 in body 7, this fire-retardant core 6 is provided with through hole, described intake interface 5 inwall is fixedly equiped with elastic rubber fitting 2 by elastic component, this elastic rubber fitting 2 is positioned at below intake interface 5, and the area of this elastic rubber fitting is greater than the area connecing gas port.Be positioned at intake interface lower end in housing 7 and be provided with step position 3, elastic rubber fitting 2 is under pressure and is stuck in when rising in this step position 3 and blocks intake interface 5.
In addition, be provided with the safety net 4 be made up of thermoplastic in intake interface 5, this safety net is provided with air-vent.Can expand when this safety net is heated, thus air-vent extruding is closed.
Through hole on fire-retardant core is less than the diameter of the port towards interface of giving vent to anger towards the diameter of the port in intake interface direction.The through hole of spark arrester is horn-like, better can stop flame.
The outer wall of interface 9 of giving vent to anger is provided with slot 8, can better clamp.The outer wall of interface of giving vent to anger is provided with screw thread, is conveniently connected with extraneous Pipe installing.
Intake interface is connected with gas pipeline, and gas outlet is then connected with other pipelines.When burning occurs in combustion gas, the burning of housing internal cause combustion gas is heated and pressure increase.Safety net is subject to heat and expands air-vent on it is closed, and elastic rubber fitting is also under pressure to move up and blocks intake interface.Thus make combustion gas cannot continue again to enter in housing.Avoid the burning continued, effectively play explosion-proof.
It should be noted that, the above is not the restriction to technical solutions of the utility model, and under the prerequisite not departing from creation design of the present utility model, any apparent replacement is all within protection domain of the present utility model.
