Description
Technical field
The utility model relates to pipe protection facility neck more particularly to a kind of pipeline expansion type fire arresters.
Background technique
Fire arrester is also commonly used on the pipeline of conveying inflammable gas.If inflammable gas is ignited, gas flame will be passed
It is multicast to entire pipe network.The generation of this danger in order to prevent will also use fire arrester.Fire arrester, which also can be used, is having open fire to set
On standby pipeline, to prevent back-fire trouble.But it cannot prevent the open fire burning of the open inflammable gas to burn and liquid, tradition
Fire arrester only have fire-retardant core and mounting flange, back-fire relief effect limitation.
Utility model content
The purpose of this utility model is to provide a kind of pipeline expansion type fire arresters, to solve the above technical problems.
The utility model uses following technical scheme to achieve the above object:
A kind of pipeline expansion type fire arrester, including ring flange, preceding fixed disk, expansion loop, rear fixed disk, metal mesh and swollen
Swollen cotton, the ring flange fix panel surface before being welded on, and the flange panel surface offers the connector for connecting pipe, institute
It states connector surrounding and offers threaded hole for fixing fire arrester, the preceding fixed disk is integrated chemical conversion type with rear fixed disk and sets
Meter, opens up the mounting groove for installing expansion loop, opens up inside the preceding fixed disk between the preceding fixed disk and rear fixed disk
There is the stomata passed through for combustion gas, the expansion loop is provided with expansion cotton, and the expansion cotton is provided with the gold for preventing flame from passing through
Belong to net.
Preferably, the expansion loop is heated, heat transfer to expansion cotton, and the stomata of preceding fixed disk is blocked up in expansion cotton expansion
Plug, the expansion cotton material are expanded perlite and expanded vermiculite mixed refractory material.
Preferably, the ring flange, preceding fixed disk, rear fixed disk and mesh materials are stainless steel.
Compared with prior art, the utility model has the advantage that the utility model structure is simple, and design rationally, is made
Valence is at low cost；When carrying out fire arrester installation, by connector access conduit, fire arrester is mounted on by pipeline by ring flange
On, gas flows through fire arrester by stomata through connecting hole, and when burning, expansion loop is heated, heat transfer to expansion cotton, expansion
The air-hole blockage of preceding fixed disk can quickly cut off the intensity of a fire by cotton expansion at the first time, and metal mesh prevents gas flame from passing through,
Dangerous generation is avoided securely and reliably preferably to promote the use of.
Detailed description of the invention

Fig. 3 is the internal structure chart of the utility model pipeline expansion type fire arrester.
In figure: 1, connector, 2, ring flange, 3, preceding fixed disk, 4, expansion loop, 5, rear fixed disk, 6, threaded hole, 7, installation
Slot, 8, metal mesh, 9, expansion cotton, 10, stomata.
Specific embodiment
The utility model is further elaborated in the following with reference to the drawings and specific embodiments.
As shown, a kind of pipeline expansion type fire arrester, including ring flange 2, preceding fixed disk 3, expansion loop 4, rear fixation
Disk 5, metal mesh 8 and expansion cotton 9, the ring flange 2 are welded on preceding 3 surface of fixed disk, and 2 surface of ring flange, which offers, to be used for
The connector 1 of connecting pipe, 1 surrounding of connector offer the threaded hole 6 for fixing fire arrester, the preceding fixed disk 3
It is integrated molded design with rear fixed disk 5, opens up between the preceding fixed disk 3 and rear fixed disk 5 for installing expansion loop 4
Mounting groove 7 offers the stomata 10 passed through for combustion gas inside the preceding fixed disk 3, and the expansion loop 4 is provided with expansion cotton 9,
The expansion cotton 9 is provided with the metal mesh 8 for preventing flame from passing through.
Utility model works principle: when carrying out fire arrester installation, by 1 access conduit of connector, pass through ring flange 2
Fire arrester is mounted on pipeline, gas flows through fire arrester by stomata 10 through connecting hole, and when burning, expansion loop 4 is heated,
Heat transfer to expansion cotton 9, the expansion of expansion cotton 9 blocks the stomata 10 of preceding fixed disk 3, can quickly cut off fire at the first time
Gesture, metal mesh 8 prevent gas flame from passing through, and avoid dangerous generation.
The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With novel introduction, in the case where not departing from the principles of the present invention and spirit, the change that is carried out to embodiment is repaired
Change, replacement and variant is still fallen within the protection scope of the utility model.
