Abstract
The invention discloses a self-circulation gas anti-freezing house-service device aiming at solving the problem that according to a gas house-service pipe in winter in the cold area, substances in gas are solidified at the low temperature, and consequently the pipe is frozen. The device comprises a gas inlet pipe, a gas pipe outer insulating layer and a gas pipe house-service valve. The gas inlet pipe is divided into an indoor section and an outdoor section. The self-circulation gas anti-freezing house-service device is characterized in that a gas circulation pipe is connected between the indoor section and the outdoor section of the gas inlet pipe, an insulating layer is additionally arranged on the outdoor section of the gas circulating pipe, and a circulation access is composed of the gas inlet pipe and the gas circulation pipe. The self-circulation gas anti-freezing house-service device is simple in structure, power of mechanical equipment is not needed, other energy consumption losses are avoided, and the self-circulation gas anti-freezing house-service device is suitable for the gas house-service pipe net of civil buildings and public buildings.
Description
Technical field
The present invention relates to gas transmission and distribution device, particularly the antifreeze house lead in device of a kind of self-loopa combustion gas.
Background technique
Gas pipeline as a kind of be the special equipment of cities and towns industry, resident's transfer the fuel, it with electric power, tap water is the same, is indispensable basic power source supply.Very important effect is played in quality of life, urban environment, all many-sides such as to provide amenities for the people of improving the people.Therefore guarantee that the unobstructed operation of gas pipeline just seems particularly important.
Northern area winter weather cold, easily there is frozen block phenomenon in gas pipeline, the ill-conditioned serious just conventional gas that have impact on industry and resident.The main cause freezed is that in coal gas, water and steam can generate water of crystallization compound with C2, C3 and C4 of gaseous state.Hyrate can reduce the circulation section of coal gas in pipeline, even blocking pipe, valve and instrument and equipment, as flowmeter, safety valve, pressure governor etc.When temperature reduction makes coal gas generate hyrate lower than its dew point, be easy to be frozen into common ice, make pipeline frozen block.
Frozen block phenomenon mostly occurs at the more shallow pipeline section of buried depth, and gas user inlet tube, and namely one section of pipe of the total valve of ingress is guided in combustion gas from distribution duct.Current gas company all once repeatedly ran into the local of causing because of pipeline frozen block and to stop the supple of gas or steam problem, and constantly explored processing method, but all very imperfect effective solution.
Summary of the invention
The invention provides the antifreeze house lead in device of a kind of self-loopa combustion gas, be intended to solve cold area gas house in winter pipe due to low temperature and cause mass sets in combustion gas, and then the pipe freezeup problem caused.
The antifreeze house lead in device of a kind of self-loopa combustion gas, this device comprises: gas inlet pipe, fuel tube external thermal insulation and fuel tube house lead in valve, wherein gas inlet pipe is divided into indoor section and outdoor section, it is characterized in that connecting a combustion gas Circulation pipe between the indoor section and outdoor section of gas inlet pipe, wherein the outdoor section of combustion gas Circulation pipe adds thermal insulation layer, and gas inlet pipe and combustion gas Circulation pipe form peripheral passage.
Combustion gas Circulation pipe between the indoor section of described gas inlet pipe and outdoor section is by being weldingly connected.
The present invention compared with existing same device, its significantly beneficial effect be embodied in:
1. the present invention does not need to increase the outer heating device of suction tude, greatly reduces expending of energy, ensure that the safe operation of pipeline simultaneously.
2. antifreezing effect is remarkable, and the density difference utilizing the temperature difference to cause provides power, and then formation circulates, and the heat of indoor is effectively passed to outdoor section gas inlet pipe.
3. this apparatus structure is simple, without any need for machinery power, without other any energy losses, is applicable to the gas house pipe network of civil building and public building.
Accompanying drawing explanation
Fig. 1 is a kind of self-loopa combustion gas antifreeze house lead in apparatus structure schematic diagram.
Number in figure: 1-gas inlet pipe; 2-fuel tube external thermal insulation; 3-fuel tube house lead in valve; 4-combustion gas Circulation pipe; 5-thermal insulation layer; 6-frozen soil layer; 7-is indoor.
Embodiment
As shown in Figure 1, the antifreeze house lead in device of a kind of self-loopa combustion gas, this device comprises: gas inlet pipe 1, fuel tube external thermal insulation 2 and fuel tube house lead in valve 3, wherein gas inlet pipe 1 is divided into indoor section and outdoor section, a part for outdoor section is arranged in frozen soil layer 6, it is characterized in that connecting a combustion gas Circulation pipe 4 between the indoor section and outdoor section of gas inlet pipe 1, wherein the outdoor section of combustion gas Circulation pipe 4 adds thermal insulation layer 5, gas inlet pipe 1 and combustion gas Circulation pipe 4 form peripheral passage, combustion gas Circulation pipe 4 between the indoor section of gas inlet pipe 1 and outdoor section is by being weldingly connected.
When winter, gas valve was opened, combustion gas by gas inlet pipe 1 enter indoor 7 use by user.During gas lockout valve in winter, tube net outside is by the impact of outer low temperature environment, and in pipe, fuel gas temperature reduces, and density increases; Pipe network in house is then by the impact of indoor 7 hot environments, and in pipe, fuel gas temperature raises, and density reduces.Indoor pipe forms circulation pipe network with outdoor pipe, and in pipe, combustion gas creates the necessary acting energy of flowing due to density difference.This acting energy effectively facilitates circulating of fuel tube inner fluid, simultaneously in the process of flowing, achieves the transmission of temperature, and when avoiding air feed interval in winter, in gas inlet pipe, gas does not flow and produces the phenomenon of frozen block.
Claims (2)
1. the antifreeze house lead in device of self-loopa combustion gas, this device comprises: gas inlet pipe, fuel tube external thermal insulation and fuel tube house lead in valve, wherein gas inlet pipe is divided into indoor section and outdoor section, it is characterized in that connecting a combustion gas Circulation pipe between the indoor section and outdoor section of gas inlet pipe, wherein the outdoor section of combustion gas Circulation pipe adds thermal insulation layer, and gas inlet pipe and combustion gas Circulation pipe form peripheral passage.
2. the antifreeze house lead in device of a kind of self-loopa combustion gas according to claim 1, is characterized in that combustion gas Circulation pipe between the indoor section of described gas inlet pipe and outdoor section is by being weldingly connected.
