Abstract
The utility model discloses an explosion-proof flame arrester for a gas pipeline, and solves the problem that the flame arrester of the gas pipeline in the prior art only performs a flame arresting function and cannot effectively prevent gas from exploding. The explosion-proof flame arrester for the gas pipeline comprises a pipeline main body (1) with an inner cavity, a flame arresting core (2) arranged at the inner part of the pipeline main body (1), and a gas inlet interface (3) arranged at one end of the pipeline main body (1), and is characterized in that a gas supply interface (4) used for being connected with the gas supply pipeline is arranged on the side wall of the pipeline main body (1), wherein a layer of safety net (5) is arranged on the gas supply interface (4); the safety net (5) made of plastic with excellent thermoplasticity is provided with a netted structure with circular through-holes; and an end cover (6) used for sealing the flame arrester is arranged at the other end of the pipeline main body (1). The explosion-proof flame arrester has a compact integral structure, is convenient to realize and requires a low cost. Therefore, the explosion-proof flame arrester is suitable for being popularized and used.
Description
Technical field
The utility model relates to a kind of spark arrester, specifically, is a kind of gas pipeline Antiexplosion and fire-stopping unit.
Background technology
At present, gas supply has become a requisite part in people's daily life, and fuel gas supply conduit also is urban construction, the development trend of community, office space.Recently, because combustion gas using method mistake, and cause the accident of gas kitchen ranges, gas meter, flow meter blast to happen occasionally, cause casualties.Traditional gas pipeline fire arrester only has the back-fire relief function, and it can not directly cut off gas supply, thereby, under the condition of operate miss or the damage of other hardware facilities, can not effectively prevent gas explosion, its safety coefficient is very low.
The utility model content
The purpose of this utility model is to overcome defects, a kind of compact overall structure is provided, realize convenient, gas pipeline fire arrester.
To achieve these goals, the scheme of the utility model employing is as follows:
The gas pipeline Antiexplosion and fire-stopping unit, comprise the pipe main body with inner chamber, be arranged on the fire-retardant core of this pipe main body inside, and the intake interface that is arranged on pipe main body one end, offer one in order to connect the air feed interface of fuel gas supply conduit at described pipe main body sidewall, be provided with one deck safety net at this air feed interface, and this safety net is made by the good plastics of thermoplastics type, it is the network structure with manhole, then be provided with to seal the end cap of spark arrester at the pipe main body other end, described fire-retardant core is made by the ripple steel band, and fire-retardant core to be provided with cross section be leg-of-mutton through hole.
Further, described fire-retardant core two ends respectively with the inwall close contact of pipe main body.
Further, be provided with screw thread at described intake interface appearance wall.
Further, described air feed interface and intake interface lay respectively at the fire-retardant core both sides; The middle part of described end cap also is provided with a diaphragm seal of being made by corrosion-resistant fexible film.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model compact conformation not only, and with low cost, realize convenient;
(2) the utility model offers one in order to connect the air feed interface of fuel gas supply conduit at described pipe main body sidewall, be provided with one deck safety net at this air feed interface, and this safety net is made by the good plastics of thermoplastics type, it is the network structure with manhole, when burning occurs in combustion gas, the safety net expanded by heating, online circular through hole is closed, thereby the combustion gas of having cut off gas pipeline continues supply, and then solved the burning of combustion gas from root, effectively prevented the blast of acutely burning and producing at confined space because of too much combustion gas, on the other hand, it is leg-of-mutton through hole that fire-retardant core is provided with cross section, and during fuel gas buring, its flame is by leg-of-mutton through hole, by the through hole outer wall flame is cooled, and then reach the knock down the flame purpose, thus effectively prevented the blast because of the tempering generation, ensured personnel's life security;
(3) material therefor is the common common material in market in the utility model, and its cost is very cheap, has established favourable basis for it promotes the use on a large scale.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic cross-section of fire-retardant core in the utility model.
Wherein, the parts name that Reference numeral is corresponding is called: 1-pipe main body, 2-fire-retardant core, 3-intake interface, 4-air feed interface, 5-safety net, 6-end cap.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, 2, the gas pipeline Antiexplosion and fire-stopping unit, comprise the pipe main body 1 with inner chamber, be arranged on the fire-retardant core 2 of this pipe main body 1 inside, and the intake interface 3 that is arranged on pipe main body 1 one ends, offer an air feed interface 4 in order to connect fuel gas supply conduit at described pipe main body 1 sidewall, be provided with one deck safety net 5 at this air feed interface 4, and this safety net 5 is made by the good plastics of thermoplastics type, it is the network structure with manhole, then is provided with to seal the end cap 6 of spark arrester at pipe main body 1 other end.When burning occurs in combustion gas, safety net 5 expanded by heating, online circular through hole is closed, thus the combustion gas of having cut off gas pipeline continues supply, and then solved the burning of combustion gas from root, effectively prevented the blast of acutely burning and producing at confined space because of too much combustion gas; On the other hand, it is leg-of-mutton through hole that fire-retardant core is provided with cross section, during fuel gas buring, its flame is by leg-of-mutton through hole, by the through hole outer wall flame is cooled, and then reach the knock down the flame purpose, thus effectively prevented the blast because of the tempering generation, ensured personnel's life security.
In the present embodiment, described fire-retardant core 2 two ends respectively with the inwall close contact of pipe main body 1.
In the present embodiment, for easy to connect, prevent gas leakage, be provided with screw thread at described intake interface 3 appearance walls.
In order better to realize more effectively extinguishing the tempering in the spark arrester by present embodiment, described air feed interface 4 lays respectively at fire-retardant core 2 both sides with intake interface 3.
According to above-described embodiment, can well realize the utility model.
