The structure of the gas decompressor comprises a gas-inlet connector, an adjusting handwheel, a gas-outlet connector and a reducing valve. An elastic component and a primary reducing valve are sequentially arranged above the inner side of a primary valve cover; a gas-inlet connector is arranged at the gas-inlet part of the primary reducing valve and at the side edge of the primary valve cover respectively, the gas-inlet connector is communicated with the primary reducing valve, the other side edge of the primary valve cover is provided with a gas-outlet connector; and the upper part of the primary valve cover is sequentially provided with a membrane, a secondary elastic component and an adjusting handwheel. The gas decompressor has the key points that the primary valve cover is provided with a heat-absorbing device, the gas decompressor heats up the gas by absorbing the external heat and solves the problems that a common gas decompressor freezes due to long-term continuous operation and fails to work normally and ensures that the operating process is smooth, safe and efficient. In addition, heating devices such as an electric heating rod and the like are cancelled, and the operation is safe and reliable.
Description
Technical field
The utility model relates to a kind of gas pressure reducer, relates in particular to a kind of decompressor that is used for inflammable gas.
Background technique
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 main component is a methane, because price is lower, is able to extensive 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 electrical heating 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 ABAP Adapter at steamer etc., just can't normally use the decompressor of charged heating stick.
Summary of the invention
The utility model provides a kind of simple in structure at deficiency of the prior art, and dispense with outer connecting power is safe and reliable, and lower-cost gas pressure reducer.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of gas pressure reducer, comprise air input joint, adjusting handle, air outlet adapter, reduction valve, the inside front of described one-level valve gap is disposed with elastic component, the one-level reduction valve, air inlet place of described one-level reduction valve, the side of one-level valve gap is provided with air input joint, described air input joint 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 component, adjusting handle, its main points are that described one-level valve gap is provided with heat sink, the utility model heats to gas by absorbing outside heat, solved common decompressor long time continuous working and freeze, the problem of cisco unity malfunction guarantees that using process is smooth and easy, safety, efficiently, and cancelled electrical heating 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 pressurized gas 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 air input joint is provided with full skirt, can strengthen heat absorption area, absorbs heat to greatest extent.
In the technique scheme, described air outlet adapter is provided with full skirt, can strengthen heat absorption area, absorbs heat to greatest extent.
Beneficial effect: the utility model 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 using process is smooth and easy, safe, efficient.
2) cancelled electrical heating rod, safe and reliable, and because electrical bar is generally 100W, during use, the cost height, the utility model heats to gas by absorbing outside heat, and cost is low.
3) enlarged use occasion, do not had ABAP Adapter or be inconvenient to draw the place of ABAP Adapter can both normally use decompressor.
4) adopt two-stage decompression, make pressurized gas 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 utility model is described in further detail:
Referring to Fig. 1, gas pressure reducer mainly is made of air input joint 6, adjusting handle 1, air outlet adapter 11, reduction valve etc.
The inside front of described one-level valve gap 9 is disposed with elastic component 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 pressurized gas 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 air input joint 6, described air input joint 6 communicates with one-level reduction valve 7, when gas after air input joint 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 component 2, adjusting handle 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 utility model 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.
Working principle, 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 usage requirement, 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.
