The utility model which is suitable for the connection modes of various pipelines can cause tempering signals to be output to a control system and can be automatically controlled, etc.
Description
Technical field
The utility model relates to the gas safe utensil, particularly relates to a kind of hydrogen and oxygen mixture gas safe that prevents tempering on the hydrogen-oxygen gas pipeline that is installed in and ends firearm.
Background technology
At present, multiple fuel gas has been widely used in industrial production and the people's life as coal gas, natural gas, liquefied petroleum gas, hydrogen and oxygen mixture etc.Because the combustibility of fuel gas, thereby its safety in utilization also had higher requirement.Hydrogen and oxygen mixture is a kind of new energy, when it uses as combustion gas, must install safety additional and end firearm on the gaseous mixture pipeline.Existing dry type is ended firearm to be by a metal tube and to place a joint in the pipe to end the fire tube to constitute, owing to have only a joint to end the fire tube, thereby end fiery weak effect, and often can not end fire fully, thereby security is relatively poor, and is difficult to repeated use.
Summary of the invention
The purpose of this utility model is to provide a kind of only bad temper energy good, reusable, easy to install, be applicable to the connected mode of various pipelines, and the tempering signal can be outputed to control system, to realize that the hydrogen and oxygen mixture gas safe of control ends firearm automatically.
For achieving the above object, the utility model provides a kind of hydrogen and oxygen mixture gas safe to end firearm, should end firearm comprises master metal tubular body 10 and places the interior only fire tube 20 of main tubular body, the main tubular body two ends are respectively equipped with air inlet 11 and gas outlet 12, it is characterized in that, be provided with two or more barrel breathables in the main tubular body and end fire tube 20, and be provided with check valve 30 at the air inlet place, respectively only separate by partition 50 between the fire tube and between only fiery tube and the check valve, end forming between fiery drum outer wall and the tubular body inwall and end fiery chamber 60.
Described only fire tube 20 is the hollow cylinders that formed by metallic particles die casting.
Described check valve 30 is made of valve body 31 and spring 32, and the tube wall of valve body is provided with air admission hole 311.
Constitute pressure buffer chamber 70 between check valve 30 and the main tubular body inwall.
The port of export in main tubular body 10 is provided with sensor 40.
As seen from the above technical solution, the utility model is owing to be provided with several fire tubes that ends spaced apart from each other in tubular body, and gas adopts infiltration type to flow, increased the gas flow resistance, thereby when tempering takes place, because the only fiery air resistance and the heat radiation of tubular body make flame extinguish in ending fiery chamber.Sensor can be passed to automatic control system with the tempering signal simultaneously, thereby realizes the automatic cut-out of combustion gas when tempering, has therefore guaranteed the safety that combustion gas is used.The utility model is applicable to the connected mode of various pipelines, and easy for installation, can also be repeatedly used, thereby practical more economically.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Consult Fig. 1, should end firearm one metal circular main tubular body 10 was arranged, the main tubular body two ends are respectively equipped with air inlet 11 and gas outlet 12, and air inlet and gas outlet are the less tubular bodies of diameter that extends to main tubular body 10 both sides, and they can be connected with various gas pipelines.Be provided with two barrel breathables in the main tubular body and end fire tube 20, also can a plurality of fire tubes that end be set according to the displacement size, should end the fire tube is the hollow cylinder that is formed by metallic particles die casting, and its intergranular hole can make gas permeation.End fiery drum outer wall and and the main tubular body inwall between certain distance is arranged, form the fiery chamber 60 of ending of an annular, this ends fiery chamber also is gas passage.Respectively end the fire tube and separated by metal spacer 50, partition is adhesively fixed with ending the fire tube, and leaves the space that gas is passed through between partition edge and the tubular body inwall.Check valve 30 is equipped with at the place at the main tubular body air inlet, this check valve 30 is made of valve body 31 and spring 32, its valve body is T-shaped, the horizontal edge of valve body withstands on the air inlet place, its center longitudinally is provided with the tubular body of a front opening, the tube wall of tubular body is provided with air admission hole 311, and the gas that enters main tubular body can be entered by this air admission hole and end in the fire tube.Check valve and first end the fire tube and are also separated by partition 50, and the tubular body of check valve passes to separate to stretch into and ends in the fire tube.Spring 32 is housed between partition and valve body.Constitute pressure buffer chamber 70 between check valve 30 and the tubular body inwall, make the gas pressure that enters in the tubular body obtain buffering.For when tempering phenomenon occurring, signal in time being passed to automatic control system, be embedded with sensor 40 in the nearly outside of main tubular body port of export end face, it links to each other with automatic control system.
Operation principle of the present utility model as shown in Figure 1, when inlet gas pressure reaches certain value, check valve 30 is backed down, the pressure buffer chamber 70 of combustion gas in check valve enters main tubular body, air admission hole on check valve 311 enters first and ends fire tube 21 then, gas enters first end the fire tube after, can only enter and end fiery chamber 60 through ending fiery barrel, enter second through second barrel that ends fiery tube again and end fire tube 22,12 discharges through the gas outlet then.When tempering takes place,, flame is extinguished in ending fiery chamber owing to end the air resistance of fire tube and the heat radiation of master metal tubular body.Simultaneously, the sensor 40 that is contained in the main tubular body port of export is sent to automatic control system with the tempering signal, thereby realizes the automatic cut-out of combustion gas when tempering, guarantees the safety that combustion gas is used.
