Description
Technical field
The utility model relates to a kind of conduit fittings, specifically a kind of gas pipeline fire arrester.
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.
Utility model content
The purpose of this utility model is to provide a kind of gas pipeline fire arrester through improvement, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of gas pipeline fire arrester, comprise flame arrester body, described flame arrester body two ends are provided with inlet end and outlet side, admission line is by the inlet end of Flange joint flame arrester body, outlet pipe is by the outlet side of Flange joint flame arrester body, and described flame arrester body is set to cylindrical shell, and in the middle part of cylindrical shell, internal diameter is greater than two-port internal diameter, the housing central section of described flame arrester body is provided with observation window, is provided with sealing rubber strip between observation window and flame arrester body; Described inlet end and outlet side are equipped with Pressure gauge, and the position near inlet end in described flame arrester body is provided with safety net, and safety net adopts thermoplastic to make, and safety net is the network structure with manhole; Described flame arrester body inside is provided with fire-retardant core, and described fire-retardant core is the iron turning of cavernous structure, and described fire-retardant core is provided with flame retardant bed close to the two ends of inlet end and outlet side, and described flame retardant bed is metal fibre interlacement.
As further program of the utility model: described observation window adopts high strength anti-explosion lucite to make.
As the utility model further scheme: described caulking gum strip adoption high-temperature resistant rubber is made.
As the utility model further scheme: the upper/lower terminal of described fire-retardant core and flame retardant bed all fits tightly with the inwall of flame arrester body.
Compared with prior art, the beneficial effects of the utility model are: the utility model arranges Pressure gauge at inlet end and outlet side, admission pressure and outlet pressure can be compared by two pressure gauge readings, observation window can be known and observes the inner stopping state of spark arrester, when pressure at two ends difference is larger, shows that spark arrester inside exists clogging, prompting personnel clear up spark arrester in time, ensure that spark arrester safety is normal to use, ensure that the air feed of gas pipeline is smooth and easy, what do not affect user uses gas demand simultaneously; The fire-retardant core of cavernous structure can be split when pipeline is on fire, weaken flame, and flame retardant bed can weaken flame further, and Fire resistances is good; When pipeline flame enters spark arrester, safety net expands due to thermoplastic, and through hole is closed, and blocks combustion gas at inlet end, cuts off the gas supply of steam line in time, effectively suppresses the condition of a fire to expand further, strengthen, plays explosion-proof.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of gas pipeline fire arrester, comprise flame arrester body 1, described flame arrester body 1 two ends are provided with inlet end 2 and outlet side 3, admission line connects the inlet end 2 of flame arrester body 1 by flange 4, outlet pipe connects the outlet side 3 of flame arrester body 1 by flange 4, described flame arrester body 1 is set to cylindrical shell, and internal diameter is greater than two-port internal diameter in the middle part of cylindrical shell, the housing central section of described flame arrester body 1 is provided with observation window 5, described observation window 5 adopts high strength anti-explosion lucite to make, sealing rubber strip 6 is provided with between observation window 5 and flame arrester body 1, described sealing rubber strip 6 adopts high-temperature resistant rubber to make, described inlet end 2 is equipped with Pressure gauge 7 with outlet side 3, and in described flame arrester body 1, the position of inlet end 2 is provided with safety net 8, safety net 8 adopts thermoplastic to make, and safety net 8 is for having the network structure of manhole, described flame arrester body 1 inside is provided with fire-retardant core 9, described fire-retardant core 9 is the iron turning of cavernous structure, described fire-retardant core 9 is provided with flame retardant bed 10 close to inlet end 2 and the two ends of outlet side 3, described flame retardant bed 10 is metal fibre interlacement, and the upper/lower terminal of described fire-retardant core 9 and flame retardant bed 10 all fits tightly with the inwall of flame arrester body 1.
Operation principle of the present utility model is: the utility model is connected with gas pipeline with the flange of outlet side 3 by inlet end 2, the Pressure gauge 7 of inlet end 2 is for measuring admission pressure, the Pressure gauge 7 of outlet side 3 is for measuring atmospheric pressure, when admission pressure and outlet pressure pressure reduction excessive time, the stopping state of flame arrester body 1 inside is observed by observation window 5, thus spark arrester can be cleared up timely, do not affect gas supply conduit; When catching fire in pipeline, flame scurries into flame arrester body 1 by outlet side 3, the flame retardant bed 10 being positioned at outlet side 3 can slow down the intensity of a fire, when flame enters fire-retardant core 9, weakened further by the cavernous structure of fire-retardant core 9, split, after entering flame in flame arrester body 1, temperature in flame arrester body 1 raises, be in the safety net 8 at inlet end 2 place due to thermoplastic effect, plastic expansion, thus manhole is closed, combustion gas is blocked at inlet end 2 place, avoids flame and contact combustion gas further thus cause condition of a fire increasing, pipe explosion.
