Abstract
The utility model particularly relates to and discloses a pipeline fire barrier provided with a safety net. The pipeline fire barrier comprises an inlet reducing shell (1), an outlet reducing shell (2), a fire-resistance core (3) and the safety net (4), wherein a big head and a small head of the shell (1) are sequentially provided with a flange plate (5) and a flange plate (6); a big head and a small head of the shell (2) are sequentially provided with a flange plate (7) and a flange plate (8); the fire-resistance core (3) is clamped between the flange plate (5) and the flange plate (7); the pipeline fire barrier is characterized in that the fire-resistance core (3) is provided with a plurality of layers of metal fiber fabrics or metal fiber sintering felts, thus having good fire retardance function. Particularly, the safety net (4) is made of plastic with good thermoplasticity and is set into a net-shaped structure provided with a plurality of tiny circular through holes, so that the plastic net expands when being heated during tempering, the through holes on the plastic net are closed, the continuous supply of gas can be cut off, excessive gas is effectively prevented from burning and exploding intensively in a pipeline, and the safety is guaranteed. Flanges are respectively arranged at the two ends of the inlet reducing shell and the outlet reducing shell, so that the pipeline fire barrier is conveniently connected with the pipeline and is compact in structure. The fire-resistance core and the safety net are made of materials which are low in price and rich in market resources, so that the pipeline fire barrier is convenient to popularize and apply.
Description
Technical field
The utility model relates to a kind of conduit fittings, is specifically related to a kind of band safety net pipeline spark arrester.
Background technology
The flammable explosive gas such as coal gas, oxygen, device in Gas, oil gas catch fire in pipeline or equipment, and if do not stoped, flame will spread, and causes that a large amount of gas acutely burns, and causes equipment or pipeline to explode because of superpressure.Thereby, usually in the flammable explosive gas pipeline, spark arrester is installed, play the effect that prevents that external flame from scurrying into the equipment that there is flammable explosive gas, pipeline or stoping flame to spread at equipment, pipeline enclosure.At present, traditional spark arrester mostly only has the back-fire relief function, and can not directly cut off combustion gas, continues supply, in the situation of operate miss or the damage of other hardware facilities, can not effectively prevent the violent combustion explosion of gas, and its safety coefficient is very low.
Therefore, for solving the problems of the technologies described above, be necessary to provide a kind of large spark arrester of security that self can be explosion-proof.
The utility model content
When being to provide a kind of tempering, the purpose of this utility model can automatically cut off the band safety net pipeline spark arrester of source of the gas.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of band safety net pipeline spark arrester, comprise import reducing housing (1), outlet reducing housing (2), fire-retardant core (3), safety net (4), described housing (1) major part and microcephaly are disposed with ring flange (5) and (6), described housing (2) major part and microcephaly are disposed with ring flange (7) and (8), described fire-retardant core (3) is held between ring flange (5) and (7), it is characterized in that described import reducing housing microcephaly is provided with safety net, can cut off source of the gas in good time, prevent the violent combustion explosion of gas.
Band safety net pipeline spark arrester of the present utility model, be set to the gripper shoe (301) with through hole in the middle of described fire-retardant core (3), be fixed with net metal fiber flame retardant bed (302) on the gripper shoe two sides, gripper shoe and ring flange (5) and (7) contact position are provided with gasket seal (303).During flame process flame retardant bed, metal fibre interlacement or metallic fiber sintered felt are cooled to rapidly the fray-out of flame temperature by high-temperature gas, the flame automatic distinguishing.
Described safety net (4) by thermoplasticity good plastics make, be set to have the network structure of some small manholes.When flame enters spark arrester, the plastic wire heat expands, the through hole closure, thus cut off source of the gas, effectively prevent too much gas violent combustion explosion in pipeline.
Compared with prior art, the utlity model has following features and beneficial effect: described fire-retardant core (3) is equipped with multiple layer metal fabric or metallic fiber sintered felt, can play good back-fire relief effect.Especially described safety net (4) is selected the good plastics of thermoplasticity, be set to have the network structure of some small manholes, during tempering, the plastic wire heat expands, through hole closure on it, thereby cut off the gas sustainable supply, can effectively prevent too much gas violent combustion explosion in pipeline, ensure safety.Import and export reducing housing two ends and all be equipped with flange, easy to connect with pipeline, compact conformation.Fire-retardant core and safety net material price are cheap, and market resource is abundant, easy to utilize.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment.
The specific embodiment
With reference to Figure of description 1, by safety net (4) melting welding in import reducing housing (1) microcephaly, ring flange (5) and (6) are welded on to import reducing housing (1) successively and hold greatly and small end, ring flange (7) and (8) are welded on to outlet reducing housing (2) successively and hold greatly and small end.Adopt bolt, nut, rely on ring flange (5) and (7) by fire-retardant core (3) sealed holding between import and export reducing housing two big end surface.
Claims (3)
1. be with safety net pipeline spark arrester for one kind, comprise import reducing housing (1), outlet reducing housing (2), fire-retardant core (3), safety net (4), described housing (1) major part and microcephaly are disposed with ring flange (5) and (6), and described housing (2) major part and microcephaly are disposed with ring flange (7) and (8), described fire-retardant core (3) is held between ring flange (5) and (7), it is characterized in that described import reducing housing microcephaly is provided with safety net.
2. band safety net pipeline spark arrester as claimed in claim 1, be set to the gripper shoe (301) with through hole in the middle of described fire-retardant core (3), be fixed with net metal fiber flame retardant bed (302) on the gripper shoe two sides, gripper shoe and ring flange (5) and (7) contact position are provided with gasket seal (303).
3. band safety net pipeline spark arrester as claimed in claim 1, described safety net (4) by thermoplasticity good plastics make, be set to have the network structure of some small manholes.
