The outline of described air flue trunnion adapter sleeve 203 and the inlet end of described air flue trunnion 202 are tightly connected, and its form be tightly connected is for being threaded;
The outlet side of described air flue trunnion 202 is connected with flameproof enclosure 201, and the sidewall of described flameproof enclosure 201 is provided with multiple through hole 2010 uniformly; Namely the inwall of flameproof enclosure 201 is provided with multiple through hole 2010 uniformly to outer wall.The shape of described flameproof enclosure 201 is cylindrical shape with end cap or conical tube.Flameproof enclosure 201 is for control flow check after the rock gas gas ignition in it, and what its combustion flame can not be random upwards altering or running helter-skelter to other direction, makes its rock gas burning of gas safer, thus ensures the personal safety of operator.
In addition, by arranging adjustment air door circle 206, the circulation of rock gas gas can also be controlled, thus after controlling rock gas gas ignition, the size of its burned flame, and then the personal safety ensureing operator.
The connection of each modular construction adopts and is tightly connected above, is that the rock gas gas preventing from flowing through leaks in the junction of each assembly.
Wherein, burner 200 can be made up of copper, iron, steel, stainless steel and other metal materials.
Wherein, flameproof enclosure 201 can be made up of copper, iron, stainless steel and other metal materials, can also be made up of stupalith.
The flameproof enclosure 201 of stupalith, when rock gas gaseous combustion is longer or when repeatedly using, easily occurs explosion, cause burned flame to go hither and thither, therefore, there is potential safety hazard, and directly impact uses the personal safety of the operator of this device.
The flameproof enclosure 201 of stainless steel material, because its heatproof is higher, and its density is far longer than the density of stupalith, therefore, when rock gas gaseous combustion, there will not be the phenomenon of explosion, eliminates potential safety hazard.The serviceable life of flameproof enclosure 201 also can be extended.
The flameproof enclosure 201 of copper product, compared with the flameproof enclosure 201 of stupalith, its resistance to gentle density is also far longer than stupalith, and therefore, its serviceable life is also longer.Compared with the flameproof enclosure 201 of stainless steel material, its Costco Wholesale is higher than the flameproof enclosure 201 of stainless steel material.
The preferred plan of flameproof enclosure 201 of the present invention is stainless steel material.
Fig. 5 is the use principle figure of rock gas in-line calibration device of the present invention, during use, is communicated with by the air intake opening 101 of standard scale 100 by connecting pipe 400 with the subscriber's meter gas outlet 301 of subscriber's meter 300.Then rock gas gas subscriber's meter 300, standard scale 100 will flow into burner 200.Rock gas gas in ignition combustion device 200, then the variable of subscriber's meter 300 and standard scale 100 is read respectively, and by the variable of subscriber's meter 300 compared with the variable of standard scale 100, if the variable of subscriber's meter 300 is in the variable error range of standard scale 100, then subscriber's meter is qualified, can extend use in 6 years; If the variable of subscriber's meter 300 is not in the error range of the variable of standard scale 100, namely the variable of subscriber's meter 300 is greater than or less than the variable error range of standard scale 100, then subscriber's meter is defective, should change in time.
