Abstract
The utility model relates to a double-core-plate pipeline fire barrier which comprises an inlet cone-shaped shell (1) and an outlet cone-shaped shell (2). The two ends of the inlet cone-shaped shell (1) are provided with a flange plate (3) and a flange plate (4). A core plate (7) is arranged in the inlet cone-shaped shell (1). The two ends of the outlet cone-shaped shell (2) are provided with a flange plate (5) and a flange plate (6), and a core plate (8) is arranged in the outlet cone-shaped shell (2). The double-core-plate pipeline fire barrier is characterized in that the core plate (8) is formed by overlaying a plurality of layers of wire meshes and can have the function of retarding fire. The core plate (7) is made of plastic of good thermo-plasticity, and is of a plate-like structure provided with a plurality of tiny round through holes. The plastic core plate is expanded with heat and the through holes in the plastic core plate are closed, so that continuous supply of gas is cut off, and therefore the excessive gas can be effectively prevented from burning rapidly and exploding in the pipeline. The two ends of the inlet cone-shaped shell and the two ends of the outlet cone-shaped shell are provided with flanges, connection is convenient, and the structure is simple. The material price of the core plates is low, and the safety factor is improved greatly due to combined action of the double core plates.
Description
Technical field
The utility model relates to a kind of conduit fittings, is specifically related to a kind of twin-core coil pipe road spark arrester.
Background technology
Spark arrester is one of main accessories on industry and civil pipeline, usually is arranged in the flammable explosive gas pipeline, plays and prevents that external flame from scurrying into the effect that the equipment, pipeline or the prevention flame that have flammable explosive gas spreads at equipment, pipeline enclosure.At present, traditional spark arrester mostly only plays the back-fire relief effect, and can not directly cut off gas, continues supply, can not effectively prevent the violent combustion explosion of gas, also has the problems such as complex structure, the accuracy of manufacture are low, poor sealing performance.
Therefore,, for solving the problems of the technologies described above, be necessary to provide a kind of anti-detonation security large spark arrester.
The utility model content
The purpose of this utility model is to provide a kind of twin-core coil pipe road spark arrester that can cut off source of the gas.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of twin-core coil pipe road spark arrester, comprise import conical shell (1) and outlet conical shell (2), described conical shell (1) two ends are provided with ring flange (3) and (4), inside is provided with core dish (7), described conical shell (2) two ends are provided with ring flange (5) and (6), inside is provided with core dish (8), it is characterized in that in described import and export conical shell being disposed with core dish (7) and the fire retardant core plate (8) that cuts off source of the gas, the acting in conjunction of twin-core dish is more safe and reliable.
Twin-core coil pipe of the present utility model road spark arrester, described core dish (8), for multiple layer metal silk screen stack thing, plays the back-fire relief effect.
Described core dish (7) is selected the good plastics of thermoplasticity, is set to have the disk-like structure of some small manholes.Plastic core dish heat expands, and through hole is closed, thereby cuts off source of the gas, prevents that effectively too much gas from exploding in the pipeline internal combustion.
Compared with prior art, the utlity model has following features and beneficial effect: described core dish (8), for multiple layer metal silk screen stack thing, can play certain back-fire relief effect.Described core dish (7) is selected the good plastics of thermoplasticity, is set to have the disk-like structure of some small manholes.Plastic core dish heat expands, and the through hole on it is closed, thereby cuts off the gas sustainable supply, can effectively prevent too much gas violent combustion explosion in pipeline.Import and export the conical shell two ends and all be equipped with flange, easy to connect, simple in structure.The core disk material is cheap, and twin-core dish acting in conjunction safety coefficient improves greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
With reference to Figure of description 1, ring flange (3) and (4) are welded on import conical shell (1) two ends, ring flange (5) and (6) are welded on outlet conical shell (2) two ends.
Fire retardant core plate (8) is placed in outlet conical shell (2).
To cut off source of the gas core dish (7) and be placed in import conical shell (1).
With flange (4) be connected 6) adopt bolt, nut, gasket seal to connect.
Claims (3)
1. twin-core coil pipe road spark arrester, comprise import conical shell (1) and outlet conical shell (2), described conical shell (1) two ends are provided with ring flange (3) and (4), inside is provided with core dish (7), described conical shell (2) two ends are provided with ring flange (5) and (6), inside is provided with core dish (8), it is characterized in that in described import and export conical shell being disposed with core dish (7) and the fire retardant core plate (8) that cuts off source of the gas.
