In the combustion gas of domestic present use-the low pressure regulator is a lot, but rarer companion's thermic devices or companion's thermal effect are bad, therefore only are applicable to comparatively dry gas or the not too low area of temperature, for north cold area, if use the bigger combustion gas of humidity, after the pressure regulation, gas pressure reduces, when gas consumption is big, pressure governor interior diaphragm space can produce freeze stifled, cause gas flow to reduce, the air feed deficiency may stop air feed when serious.
The model utility content
The utility model purpose is to provide a kind of small flow combustion gas to accompany hot pressure regulation air feeder for the deficiency that solves above-mentioned technology.
In order to achieve the above object, technological scheme provided by the utility model is: it comprises in the combustion gas-the low pressure pressure adjusting structure, in the described combustion gas-input end of low pressure pressure adjusting structure links to each other with first companion's heat structure and second companion's heat structure respectively with output terminal, described first companion's heat structure links to each other with the output terminal valve with the input end valve respectively with second companion's heat structure, and described input end valve links to each other with low-pressure line with middle pressure pipeline respectively with the output terminal valve.
Further, in the combustion gas-the low pressure pressure adjusting structure comprises pressure gauge and Safety relief valve.
Further, first companion's heat structure is made up of self temperature control heating tape and seamless steel pipe, in seamless steel pipe one end and the combustion gas-the low pressure pressure adjusting structure is connected with flange, and the other end is welded on the input end valve steel pipe afterwards.
Further, second companion's heat structure is made up of self temperature control heating tape and seamless steel pipe, in seamless steel pipe one end and the combustion gas-the low pressure pressure adjusting structure is connected with flange, and the other end is welded on the output terminal valve steel pipe before.
Further, first companion's heat structure all links to each other with explosion-proof electrical source by self temperature control heating tape with second companion's heat structure, can select to use separately or use simultaneously first and second companion's heat structures by power switch.Self temperature control heating tape have automatic adjusting output power, started quickly at low temperature and temperature evenly, flame-proof polyethylene or fluoroplastic insulation sheath are arranged and strengthen the zinc-plated copper wire woven shield of sheath, easy for installation, safeguard simple.
Further, utilize the pressure regulation casing with in the combustion gas-low pressure pressure adjusting structure, first and second companion heat structures, the input end valves, output terminal valve wrap up wherein.
The utlity model has following advantage: safe and reliable, stable performance, outlet pressure and accompany hot temperature to regulate within the specific limits, and keep-up pressure and temperature stabilization, companion's heat structure is promptly inserted instant heating, convenient and practical, satisfy small flow resident or commercial user's demand, guarantee to be difficult for freezing stifled phenomenon when cold area uses the bigger combustion gas of water content and cause the air feed deficiency, the reduction cost of transportation is increased economic efficiency.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: pressure pipeline in 1,2 low-pressure line, 3 pressure regulation casings, 4 input end valves, 5 output terminal valves, 6-1 first companion's heat structure, 6-2 second companion's heat structure, in 7 combustion gas-the low pressure pressure adjusting structure, 8 pressure gauges, 9 Safety relief valves, 10 explosion-proof electrical sources, 11 self temperature control heating tapes.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As shown in Figure 1, the utility model comprises in the combustion gas-low pressure pressure adjusting structure 7, in the described combustion gas-input end of low pressure pressure adjusting structure 7 links to each other with the first companion heat structure 6-1 and second companion's heat structure 6-2 respectively with output terminal, described first companion's heat structure 6-1 links to each other with output terminal valve 5 with input end valve 4 respectively with second companion's heat structure 6-2, and described input end valve 4 links to each other with low-pressure line 2 with middle pressure pipeline 1 respectively with output terminal valve 5.In the combustion gas-low pressure pressure adjusting structure 7 comprises pressure gauge 8 and Safety relief valve 9.The first companion heat structure 6-1 is made up of self temperature control heating tape and seamless steel pipe, in seamless steel pipe one end and the combustion gas-low pressure pressure adjusting structure 7 usefulness flanges are connected, and the other end is welded on input end valve 4 steel pipe afterwards.The second companion heat structure 6-2 is made up of self temperature control heating tape and seamless steel pipe, in seamless steel pipe one end and the combustion gas-low pressure pressure adjusting structure 7 usefulness flanges are connected, and the other end is welded on output terminal valve 5 steel pipe before.First companion's heat structure 6-1 all links to each other with explosion-proof electrical source 10 by self temperature control heating tape 11 with second companion's heat structure 6-2, can select to use separately or use simultaneously first and second companion's heat structures by power switch.
