Abstract
The utility model discloses a pressure gradient manual odorizing device for natural gas transmission and distribution stations, which comprises an odorant adding structure, an odorant storage structure, an odorant quantity display structure, an odorant adding control structure and an odorant output structure. The odorant is added from the odorant adding structure and is stored in the odorant storage structure which is connected with the output structure through the odorant adding control structure. The odorizing device has the advantages of being simple and convenient in operation, low in cost, simple and easy in assembly, and applicable to odorizing in small capacity natural gas transmission and distribution stations.
Description
Technical field
The utility model relates to the differential manual device for adding odor in a kind of natural gas transmission and distribution station.
Background technique
Character according to rock gas, it belongs to a kind of colourless, tasteless inflammable gas, when rock gas can't be found from sense of smell if any leaking the people as domestic fuel, therefore national regulation requires to add smelly dose in rock gas, when the content of rock gas in the air reach lower explosion limit 20% the time, just can discover by sense of smell and to obtain.But in the less CNG transmission ﹠ distribution station of gas consumption, how to make a kind of easy, handy device for adding odor and remain a difficult problem.
The model utility content
The utility model purpose is to provide a kind of rock gas device for adding odor 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 that smelly dose adds structure, smelly dose of memory structure, smelly dosage indication structure, smelly dose adds control structure and export structure, described smelly dose of adding structure output terminal links to each other with smelly dose of memory structure input end, described smelly dosage indication structure input end links to each other with smelly dose of memory structure input/output terminal respectively with output terminal, described smelly dose of memory structure output terminal links to each other with the input end of export structure, described smelly dose of adding control structure input end links to each other with the natural gas line upstream, the export structure input end links to each other with the output terminal of described smelly dose of memory structure, and output terminal links to each other with the natural gas line downstream.
Further, smelly dose of adding structure comprises funnel, control valve.
Further, smelly dose of memory structure comprises the DN80 seamless steel pipe, and two ends are made up of end socket, and input end links to each other with smelly dose of adding structure, and output terminal links to each other with export structure.
Further, smelly dosage indication structure comprises level meter, end opening valve, valve suitable for reading, and valve suitable for reading links to each other respectively with smelly dose of memory structure input/output terminal with the end opening valve.
Further, smelly dose of adding control structure comprises pressure tube valve, pressure pipe, and its output terminal links to each other with the input end of described smelly dose of memory structure, and input end links to each other with the natural gas line upstream.
Further, export structure comprises connecting tube valve, connecting tube, and its input end links to each other with the output terminal of described smelly dose of memory structure, and output terminal links to each other with natural gas line.
The utlity model has following advantage: install easy to makely, simple to operation, take up an area of for a short time, cost is low, has improved benefit economical and has reduced whole investment.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: 1 funnel, 2 control valves, 3 holding vessels, 4 pressure tube valves, 5 pressure pipes, 6 natural gas lines, 7 connecting tube valves, 8 end opening valves, 9 level meters, 10 valves suitable for reading, 11 upstreams, 12 downstreams.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As shown in Figure 1, smelly dose by funnel 1 adding, open control valve 2, smelly dose enters holding vessel 3 by action of gravity, and closing control valve 2 can produce pressure reduction when the fuel gas flow in the natural feed channel, upper end pressure pipe 5 by natural gas line, pressure signal is transferred to the upper end of holding vessel, and the gravity sum of this pressure and smelly dose is greater than the following end pressure of holding vessel, and smelly dose joins in the natural gas line by connecting tube under the effect of this pressure reduction.
The top and bottom of holding vessel pick out end opening valve 8 and valve suitable for reading 10, and end opening valve 8 is connected with the upper end with the lower end of level meter 9 respectively with valve 10 suitable for reading, can observe in the holding vessel smelly dose storage volume by level meter.So that smelly dose of storage volume in time added after a little while.
It should be noted that at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
