The structure of the gas pressure reducer comprises an inlet connector, an adjusting handwheel, an outlet connector, a reducing valve, wherein an elastic component, a primary reducing valve are arranged above the inside of a primary valve cap in sequence; the inlet connector is arranged on the side edge of the primary valve cap at the position of the air inlet of the primary reducing valve, and is communicated with the primary reducing valve; the other side edge of the primary valve cap is provided with the outlet connector; the upper part of the primary valve cap is provided with a diaphragm, a secondary elastic component and the adjusting handle in sequence. The gas pressure reducer is characterized in that the primary valve cap is provided with a heat absorption device; the gas pressure reducer heat gas through absorbing external heat, thereby solving the problems that the prior pressure reducer is iced because of long-term continuously working and can not work normally, ensuring smooth, safe and high-efficient using process, and cancelling the electric heating rod and other heating equipment. Therefore, the gas pressure reducer can be used safely and reliably.
Description
Technical field
The present invention relates to a kind of gas pressure reducer, relate in particular to a kind of decompressor that is used for inflammable gas.
Background technology
Because the derived product rise in price relevant with oil, various new type of compression gases constantly are applied in the middle of the cutting industry, novel cutting gas CNG, its principal ingredient is a methane, because price is lower, is able to widespread use, be-182.5C owing to the CNG fusing point, boiling point is-161.5C, in the decompression process of externally exitting, decompressor need absorb a large amount of heats, causes common decompressor to be easy to cooling and freezes, cause the decompressor inner body to freeze and to work, for decompressor can not frozen, part decompressor at present, adopting increases electrically heated rod and comes to heat to decompressor on decompressor, see Fig. 3, its structure is, one-level reduction valve 15 is set on the valve body 14, also is provided with electrical bar 13 on the described valve body 14, but because CNG is an inflammable gas, just in case CNG reveals because of carelessness, adopt the decompressor of electrical bar structure, will cause serious security incident, and do not have the occasion of external power supply at steamer etc., just can't normally use the decompressor of charged heating rod.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of simple in structure, dispense with outer connecting power, safe and reliable, and lower-cost gas pressure reducer.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A kind of gas pressure reducer, comprise inlet suction port, control hand wheel, air outlet adapter, reduction valve, the inside front of described one-level valve gap is disposed with elastic parts, the one-level reduction valve, air inlet place of described one-level reduction valve, the side of one-level valve gap is provided with inlet suction port, described inlet suction port communicates with the one-level reduction valve, another side of one-level valve gap is provided with air outlet adapter, described one-level valve gap top is disposed with diaphragm, the secondary elastic parts, control hand wheel, its main points are that described one-level valve gap is provided with heat sink, the present invention comes to heat to gas by absorbing outside heat, solved common decompressor long time continuous working and freeze, the problem of cisco unity malfunction guarantees that use is smooth and easy, safety, efficiently, and cancelled electrically heated rod, safe and reliable.
In the technique scheme, described heat sink is a full skirt, can simplify technology, convenient production.
In the technique scheme, also be provided with the second depressurized valve on the described one-level valve gap, adopt two-stage decompression, make gases at high pressure drop to required working pressure, stable more, accurately promptly during low pressure, also safer, efficient than the decompressor of one-level decompression.
In the technique scheme, described second depressurized valve is arranged on the top of one-level reduction valve, makes things convenient for the installation of gas pressure reducer.
In the technique scheme, described inlet suction port is provided with full skirt, can strengthen endotherm area, absorbs heat to greatest extent.
In the technique scheme, described air outlet adapter is provided with full skirt, can strengthen endotherm area, absorbs heat to greatest extent.
Beneficial effect: the present invention compared with prior art has following beneficial effect:
1) solved common decompressor long time continuous working and freeze, the problem of cisco unity malfunction guarantees that use is smooth and easy, safe, efficient.
2) cancelled electrically heated rod, safe and reliable, and because electrical bar is generally 100W, during use, the cost height, the present invention comes to heat to gas by absorbing outside heat, and cost is low.
3) enlarged use occasion, do not had external power supply or be inconvenient to draw the place of external power supply can both normally use decompressor.
4) adopt two-stage decompression, make gases at high pressure drop to required working pressure, stable more, accurately promptly during low pressure, also safer, efficient than the decompressor of one-level decompression.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
Referring to Fig. 1, gas pressure reducer mainly is made of inlet suction port 6, control hand wheel 1, air outlet adapter 11, reduction valve etc.
The inside front of described one-level valve gap 9 is disposed with elastic parts 8, one-level reduction valve 7, as preferably, described one-level reduction valve 7 tops also are provided with second depressurized valve 4, adopt two-stage decompression, make gases at high pressure drop to required working pressure, promptly during low pressure, stable more, accurate, also safer, efficient than the decompressor of one-level decompression.
Air inlet place of described one-level reduction valve 7, the side of one-level valve gap 9 is provided with inlet suction port 6, described inlet suction port 6 communicates with one-level reduction valve 7, when gas after inlet suction port 6 air inlets, by one-level reduction valve 7 gas atmosphere is lowered.
Described second depressurized valve 4 place of giving vent to anger, the side of one-level valve gap 9 is provided with air outlet adapter 11, when gas after 7 decompressions of one-level reduction valve, from 4 decompressions of second depressurized valve, flow out again from air outlet adapter 11.After second depressurized, gas is more steady.
The top setting that the top of described second depressurized valve 4 is provided with diaphragm 12, described diaphragm 12 sets gradually secondary elastic parts 2, control hand wheel 1.
Described one-level valve gap 9 is provided with full skirt 5, and described one-level valve gap 9 is made for the material that is easy to heat conduction, and as preferably, the present invention is set to the aluminium of LY12.Because aluminium has heat sinking function preferably, here, it is used for absorbing heat, and to the internal gas heat release.
Principle of work, after gas enters decompressor, by one-level reduction valve 7 to its decompression, gas is again through 4 decompressions of second depressurized valve then, make gas atmosphere reach request for utilization, in the decompression procedure, because gas temperature is lower, external temperature is far longer than the temperature of gas, at this moment because full skirt and outside surface of contact are bigger, and because aluminium has good heat absorption, heat sinking function, can absorb the heat of big outside, and, prevent that effectively gas from freezing to the internal gas heat release.
Though the present invention is described by preferred embodiment, yet the present invention is not limited to embodiment as described herein, also comprises various changes and the variation done without departing from the present invention.
