Abstract
The invention discloses a kind of combustion gas anti-backfire safety devices; including a protection metal pipe (1); the protection metal pipe (1) has a cavity (2) and both ends are equipped with the gas joint (3) that can be connect with fuel gas conduit; more capillaries are connected between gas joint (1) described in two in the cavity (2), the cavity (2) is filled with extinguishing chemical (5).The present invention is a kind of to can effectively prevent that combustion gas tempering and structure be simple, reliable performance, easily manufactured combustion gas anti-backfire safety device.
Description
Technical field
The present invention relates to a kind of fireproof tempering devices, more particularly, to a kind of combustion gas anti-backfire safety device.
Background technique
Liquefied petroleum gas has the characteristics that inflammable and explosive, and once accident occurs, consequence is extremely serious.This is because liquefied petroleum
Gas is gaseous state at normal temperatures and pressures, is easily mixed with air, and the aerial volume content of liquefied petroleum gas reaches 2% left side
The right side just forms explosion gas, in case of fire source will burn or explode.Therefore safe handling liquefied petroleum gas, especially prevents fire
The generation of calamity is the cardinal task of the security of the lives and property of affecting the livelihood of every family.Safety valve for liquidefied petroleum gas has spring and rod-type two
Major class.In addition there are also electric relief valve, pilot operated safety valve, safety changeover valve, safety solution pressure valve, dead weight type safety valves etc..
Spring loaded safety valve relies primarily on the active force of spring and works, in spring loaded safety valve again have closing and it is not closed, generally
Inflammable, explosive or toxic medium should be selected closed, and steam or inert gas etc. can select Unseal type, pacify in spring
In full valve there are also strap wrenches and not strap wrenches.In the delivery outlet of lpg regulator, when pressure regulator output pressure is normal, gas
Body enters valve body tail end, is exported by valve, and when pressure regulator is out of control or output channel is damaged, when front and back generates pressure difference, valve is closed
It closes to achieve the purpose that prevent gas leak to be poisoned and prevent fire.But safety valve for liquidefied petroleum gas currently on the market makes
It is exploded with can not generate tempering at that time.
Summary of the invention
The object of the present invention is to provide a kind of combustion gas anti-backfire safety devices that can effectively prevent combustion gas tempering.
In order to solve the above technical problem, the present invention provides combustion gas anti-backfire safety device, an including metal coating
Pipe, the protection metal pipe has a cavity and both ends are equipped with the gas joint that can be connect with fuel gas conduit, the sky
More capillaries are connected between gas joint described in intracavitary two, the cavity is filled with extinguishing chemical.
The capillary is waveform capillary.
The extinguishing chemical is fire-fighting powder, water or sand.
The protection metal pipe is copper protection pipe.
The capillary is capillary plastic tube.
Combustion gas anti-backfire safety device by adopting the above technical scheme connects a combustion gas on the basis of existing safety valve
Anti-backfire safety device, when improper use generates tempering, which can make the liquefaction in liquid gas storage tank automatically by fray-out of flame
Unlikely be ignited of gas and explode.When the gas of burning is by capillary plastic tube, the gas of burning is by capillary plastic tube
It burns and breaks, the extinguishing chemical in cavity enters capillary plastic tube and rapidly extinguishes combustion gas.The present invention, should when improper use generates tempering
Device can be automatically by fray-out of flame, and structure is simple.Capillary plastic tube is equipped with protection metal pipe, can increase the strong of capillary plastic tube
Degree, effective protection capillary plastic tube are not damaged.
In conclusion the present invention is a kind of simple combustion gas tempering and structure, reliable performance, easily manufactured of can effectively prevent
Combustion gas anti-backfire safety device.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the line A-A cross-sectional view along Fig. 1.
Specific embodiment
Referring to Fig. 1 and Fig. 2, combustion gas anti-backfire safety device, including a protection metal pipe 1, protection metal pipe 1 have one
A cavity 2 and both ends are equipped with the gas joint 3 that can be connect with fuel gas conduit, are connected between two gas joints 1 in cavity 2
More capillary plastic tubes 4, cavity 2 are filled with extinguishing chemical 5.
Preferably, capillary plastic tube 4 is waveform capillary.
Specifically, extinguishing chemical 5 is fire-fighting powder, water or sand.
Specifically, protection metal pipe 1 is copper protection pipe.
Referring to Fig. 1 and Fig. 2, when the gas of burning manages interior by capillary plastic tube 4, the gas of burning is by capillary plastic tube
4 burnings are broken, and the extinguishing chemical 5 in cavity 2 rapidly extinguishes combustion gas into capillary plastic tube 4.The present invention generates tempering when improper use
When, which can be automatically by fray-out of flame, and structure is simple.Capillary plastic tube 4 is equipped with protection metal pipe 1, can increase capillary plastics
The intensity of pipe 4, effective protection capillary plastic tube 4 are not damaged.
The capillary plastic tube 4 of waveform increases the circulation path of burning gases, slows down the flow velocity of combustion gas, it is easier to blow hair
Thin plastic pipe 4, extinguishing effect is more preferable.
Combustion gas anti-backfire safety device is connected to the gas outlet of existing liquefaction air valve, so that it may which reaching prevents liquefied gas from returning
The thing of fire occurs.The combustion gas anti-backfire safety device not only has the advantages that existing safety valve, but also can effectively prevent
The generation of back-fire trouble when improper use.
