Abstract
The utility model discloses a gas decompressor for preventing decompressed gas from being liquefied, which aims to solve the problem that the stability of air stream is affected due to gas liquefaction which blocks the gas pipeline caused by temperature reduction led by the throttling effect when gas is decompressed. The gas decompressor comprises a high pressure gauge, a low pressure gauge, a safety valve, a high pressure chamber, a low pressure chamber, a valve, a mandrill and a heater. The heater is arranged in the high pressure chamber and/or the low pressure chamber or outside the high pressure chamber and/or the low pressure chamber to heat the gas entering the high pressure chamber and/or the low pressure chamber. The utility model is suitable for decompressing gas with the gas condensation point which is not significantly different from the environment temperature.
Description
Technical field
The utility model relates to a kind of Gas pressure reducer, particularly a kind of Gas pressure reducer that prevents gas decompression back liquefaction.
Background technique
Existing Gas pressure reducer all is after making gas pressure reduce to required scope by reduction valve, makes gas input using system through other control valve fine tuning again.When gas reduced pressure through decompressor, the pressurized gas of import entered low pressure chamber diffusion decompression by the hyperbaric chamber through the throttle clearance of valve and valve seat, because the existence of throttle effect, the phenomenon that temperature reduces appears in regular meeting.The gas that some condensation points and ambient temperature are more or less the same, the phenomenon of liquefaction takes place in gas because the temperature reduction that throttle effect caused can occur that ambient temperature is higher than its condensation point, causes pipeline blockage and then has influence on the stability of air-flow.
Summary of the invention
The purpose of this utility model provides a kind of Gas pressure reducer that prevents gas decompression back liquefaction, in the time of can solving gas that existing gas pressure reducer is more or less the same to some condensation points and ambient temperature and reduce pressure, cause gas to liquefy because the temperature that throttle effect caused reduces, cause gas piping to stop up and then have influence on the problem of the stability of air-flow.
For solving the problems of the technologies described above, the Gas pressure reducer of gas decompression back liquefaction that prevents of the present utility model comprises high pressure gauge, low-pressure meter, safety valve, hyperbaric chamber, low pressure chamber, valve, push rod and heating equipment, by the gas heating of heating equipment to the process decompressor.
Hyperbaric chamber of the present utility model is connected with high pressure gauge and safety valve, low pressure chamber is connected with low-pressure meter, push rod is connected with valve, and the hyperbaric chamber is connected with low pressure chamber through valve, and the pressurized gas of import enter low pressure chamber diffusion decompression by the hyperbaric chamber through the throttle clearance of valve and valve seat.Heating equipment can be built in hyperbaric chamber and/or the low pressure chamber, and makes heating equipment and gas-insulated by insulator, to avoid the generation of accident.Heating equipment also can place hyperbaric chamber and/or low pressure chamber outside, directly hyperbaric chamber and/or underpressure chamber part is heated.When external, heating equipment is heater band or heating tape or other modes.
Use the Gas pressure reducer of band heating equipment described in the utility model, can the gas that enter Gas pressure reducer be heated, also can heat post-decompression gas, or simultaneously the hyperbaric chamber and the low pressure chamber of Gas pressure reducer heated, total effect is to make the true temperature of decompression back gas be not less than ambient temperature, to guarantee that gas can not liquefy because of the throttling expansion effect.The pipeline blockage that effectively prevents so cause is guaranteed the stability of air-flow.

Embodiment:
For further setting forth technological means and the effect of the utility model for realizing that goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to structure, feature, effect and embodiment according to the Gas pressure reducer of the band heating equipment that the utility model proposes, describe in detail as after.
At first referring to Fig. 1 and Fig. 2.Fig. 1 has showed the structure of Gas pressure reducer of the present utility model; Fig. 2 has illustrated the air motion of Gas pressure reducer of the present utility model.
Each parts label shown in the accompanying drawing:
1 high pressure gauge, 2 low-pressure meters, 3 safety valves, 4 valve,
5 hyperbaric chambers, 6 low pressure chambers, 7 push rods, 8 heating equipments.
This decompressor comprises high pressure gauge 1, low-pressure meter 2, safety valve 3, valve 4, hyperbaric chamber 5, low pressure chamber 6, push rod 7 and built-in heating equipment 8.Outside pressurized gas enter decompression table hyperbaric chamber 5 from Fig. 2 arrow institute target inlet, and can open valve 4 this moment by regulating push rod 7, and the pressurized gas of import enter low pressure chamber 6 by hyperbaric chamber 5 behind expenditure and pressure like this, and lead to work system through outlet.Change the opening degree of valve 4 by the adjusting of push rod 7, thereby regulate the throughput of pressurized gas and reach required force value.To be gas reduce to the process of low pressure by high pressure to this process, is a throttling expansion process, and the gas temperature after the step-down is lower than the temperature before the step-down.If institute's using gases condensation point and ambient temperature or room temperature are more or less the same, then very easily liquefy at low pressure chamber 6 or outlet, cause the obstruction of pipeline and then have influence on the stability of air-flow.8 pairs of gases that enter low pressure chamber 6 of heating equipment heat, and because of the temperature that throttling expansion causes reduces, Gas pressure reducer can stably be worked with compensation, avoid the generation of gas liquefaction phenomenon.When it is built-in, should be to the heating equipment that gas in the decompressor heats by insulator and gas-insulated to avoid the generation of accident.
The above is preferred embodiment of the present utility model only, is not model utility is done any pro forma restriction.In fact, when built-in, heating equipment 8 also can heat the gas that enters decompressor hyperbaric chamber 5 from gas cylinder, or simultaneously the temperature reduction that causes through throttling expansion with compensation gas is heated in hyperbaric chamber 5 and low pressure chamber 6.Heating equipment 8 also can be placed on the outside of decompressor with alternate manners such as heater band or heating tapes, and the hyperbaric chamber 5 and/or the low pressure chamber 6 of decompressor heated, and uses during liquefaction easily through decompressor decompression back at gas, with the stability of assurance air-flow.
Any those skilled in the art can utilize the technology contents of above-mentioned prompting to make some change in not breaking away from the technical solutions of the utility model scope.But every content that does not break away from technical solutions of the utility model to any simple modification, equivalent variations and modification that above embodiment did, all still belongs to the scope of technical solutions of the utility model according to technical spirit of the present utility model.
