Abstract
The utility model relates to a novel backfire explosion-proof device which is characterized in that the device comprises a shell (13), a gas inlet pipe joint (11), a gas outlet pipe joint (15) and backfire explosion-proof materials (14), the shell (13) is in a cylindrical structure, the backfire explosion-proof materials (14) are filled in the shell (13), and the two ends of the shell (13) are respectively in threaded connection with the gas inlet pipe joint (11) and the gas outlet pipe joint (15). After gas passes through the device and is filtered by internal backfire materials, the gas is dispersed into single or a plurality of molecules and passes through. If backfire occurs, flames are extinguished because the combustion is not supported by enough gas when the flames pass through the device. Thereby, the novel backfire explosion-proof device has the advantages that the liquid storage tank (or filter) arranged behind is prevented from exploding and the occurrence of explosion is avoided.
Description
Technical field
The utility model relates to a kind of novel tempering explosion-protection equipment, mainly is used on the pipeline of hydrogen or oxygen gas conveying.
Background technology
Tempering refluxes for fuel gas pressure in pipeline causes burning gases inadequately, thereby the pipe explosion that causes is not installed in pipelines more of the prior art and is prevented back-fire arrangement, though have fireproof tempering device has been installed, but effect is undesirable, easily explosion caused phenomenon.
Summary of the invention
The purpose of this utility model just provides a kind of novel tempering explosion-protection equipment, takes place with easy the to be explosion caused phenomenon that solves prior art.The technical solution of the utility model is: a kind of novel tempering explosion-protection equipment, it is characterized in that: comprise shell (13), air inlet pipe joint (11), escape pipe joint (15) and tempering explosion-proof lamp (14), described shell (13) is a tubular construction, described tempering explosion-proof lamp (14) is filled in the inside of shell (13), and air inlet pipe joint (11) and escape pipe joint (15) have been threaded respectively at the two ends of described shell (13).
Two ends at shell (13) are respectively equipped with internal thread, and described air inlet pipe joint (11) and escape pipe joint (15) are provided with the external screw thread that cooperatively interacts with internal thread.
The periphery of described air inlet pipe joint (11) and escape pipe joint (15) is respectively equipped with rubber blanket (12), and fastening by nut (16), fits tightly the two ends in shell (13).
Described tempering explosion-proof lamp (14) is the copper mesh of multilayer stack.The utility model has the advantages that: when gas passes through this device; through inner tempering filtration of material; dispersion becomes single or several molecule passes through; if tempering situation; thereby flame during by it owing to can not get its burning of too many gas support and extinguish; fluid reservoir (or filter) with the protection back does not produce blast, has prevented the generation of explosion phenomenon.

The specific embodiment
Referring to Fig. 1 to Fig. 3, the utility model comprises a kind of novel tempering explosion-protection equipment, it is characterized in that: comprise shell (13), air inlet pipe joint (11), escape pipe joint (15) and tempering explosion-proof lamp (14), described shell (13) is a tubular construction, described tempering explosion-proof lamp (14) is filled in the inside of shell (13), and air inlet pipe joint (11) and escape pipe joint (15) have been threaded respectively at the two ends of described shell (13).
Two ends at shell (13) are respectively equipped with internal thread, and described air inlet pipe joint (11) and escape pipe joint (15) are provided with the external screw thread that cooperatively interacts with internal thread.
The periphery of described air inlet pipe joint (11) and escape pipe joint (15) is respectively equipped with rubber blanket (12), and fastening by nut (16), fits tightly the two ends in shell (13).
Described tempering explosion-proof lamp (14) is the copper mesh of multilayer stack.
The operation principle of this device: when hydrogen or oxygen gas installs by this; through inner tempering filtration of material; dispersion becomes single or several molecule passes through; if tempering situation; thereby flame owing to can not get its burning of too many gas support and extinguish, does not produce blast with the fluid reservoir (or filter) of protection back during by it.
