Abstract

The utility model discloses a kind of industrial and commercial units' air feed seperating range control device, comprise pressure regulation main pipeline, pressure regulation main pipeline is provided with main voltage regulator, described pressure regulation main pipeline is also connected with two pressure regulation branch roads, be in parallel between these two pressure regulation branch path, a pressure regulation branch road is provided with first-class gauge and the first electric ball valve wherein, another pressure regulation branch road is provided with second gauge and the second electric ball valve, and described first-class gauge, the first electric ball valve, second gauge are connected with PLC control cabinet respectively with the second electric ball valve.The utility model is by the flowmeter of two different models in parallel on pressure regulation main pipeline, to carry out accurate-metering to the flow of industrial and commercial units' gas equipment when starting and when normally running after starting respectively, evade existing flowmeter and there is the situation of low load with strong power by data traffic type selecting when starting, air feed loses to avoid gas company to occur.

Description

Industrial and commercial units' air feed seperating range control device
Technical field
The utility model relates to natural gas supply equipment, specifically relates to a kind of industrial and commercial units' air feed seperating range control device.
Background technique
The larger industrial and commercial user's gas equipment of current part instantaneous flow when starting is comparatively large, after starting normal when instantaneous flow starts relatively when running instantaneous flow to reduce amplitude larger.Existing flowmeter design type selecting is generally selected by data on flows when starting, the situation of selected flowmeter ubiquity low load with strong power during actual motion, causes gas company's air feed loss.
Model utility content
Based on above-mentioned technical problem, the utility model provides a kind of industrial and commercial units' air feed seperating range control device.
The technical solution that the utility model adopts is:
A kind of industrial and commercial units' air feed seperating range control device, comprise pressure regulation main pipeline, pressure regulation main pipeline is provided with main voltage regulator, described pressure regulation main pipeline is also connected with two pressure regulation branch roads, be in parallel between these two pressure regulation branch path, a pressure regulation branch road is provided with first-class gauge and the first electric ball valve wherein, another pressure regulation branch road is provided with second gauge and the second electric ball valve, and described first-class gauge, the first electric ball valve, second gauge are connected with PLC control cabinet respectively with the second electric ball valve.
Preferably, the corresponding gas equipment of described first-class gauge uses when when starting, instantaneous flow is larger, and when the corresponding gas equipment of described second gauge normally runs upon actuation, instantaneous flow significantly reduces rear use.
Preferably, described first-class gauge, the first electric ball valve, second gauge and the second electric ball valve access explosion-proof tank respectively by instation circuit, and described PLC control cabinet is by station external circuit access explosion-proof tank.
Advantageous Effects of the present utility model is:
The utility model is by the flowmeter of two different models in parallel on pressure regulation main pipeline, to carry out accurate-metering to the flow of industrial and commercial units' gas equipment when starting and when normally running after starting respectively, evade existing flowmeter and there is the situation of low load with strong power by data traffic type selecting when starting, air feed loses to avoid gas company to occur.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
Fig. 1 is structural principle schematic diagram of the present utility model.
Embodiment
By reference to the accompanying drawings, a kind of industrial and commercial units' air feed seperating range control device, comprises pressure regulation main pipeline 1, and one end of pressure regulation main pipeline 1 is high voltage terminal, and the other end is low voltage terminal, and pressure regulation main pipeline 1 is provided with main voltage regulator 2.Pressure regulation main pipeline 1 is also connected with two pressure regulation branch roads, is respectively the first pressure regulation branch road 3 and the second pressure regulation branch road 4, first pressure regulation branch road 3 and the second pressure regulation branch road 4 and is in parallel.First pressure regulation branch road 3 is provided with first-class gauge 5 and the first electric ball valve 6, and the corresponding gas equipment of type selecting of first-class gauge 5 uses when when starting, instantaneous flow is larger.Second pressure regulation branch road 4 is provided with second gauge 7 and the second electric ball valve 8, and when the corresponding gas equipment of type selecting of second gauge 7 normally runs upon actuation, instantaneous flow significantly reduces rear use.First-class gauge 5, first electric ball valve 6, second gauge 7 are connected with PLC control cabinet 9 respectively with the second electric ball valve 8.Specific as follows: described first-class gauge 5, first electric ball valve 6, second gauge 7 and the second electric ball valve 8 access explosion-proof tank 10 respectively by instation circuit, described PLC control cabinet 9 is by station external circuit access explosion-proof tank 10.
The utility model is by carrying out seperating range control transformation to industrial and commercial units' flowmeter, and replacing manual ball valve is electric ball valve, and is controlled by PLC control cabinet, evades flowmeter low load with strong power metering loss.Working procedure of the present utility model is roughly as follows: when gas equipment starts, and instantaneous flow is comparatively large, now uses the first-class gauge 5 of large discharge to measure; When startup completes, proceed to when normally running, flux signal is passed to PLC control cabinet 9 by first-class gauge 5, PLC control cabinet 9 controls the first electric ball valve 6 by a road (the first pressure regulation branch road 3) slowly closing of Large flow, and control the second electric ball valve 8 and slowly open, one tunnel (the second pressure regulation branch road 4) of slow unlatching small flow metering, make second gauge 7 can carry out accurate-metering by the measures range of flowmeter (20%-80%), avoid the generation of low load with strong power situation.
The part do not addressed in aforesaid way is taked or uses for reference prior art to realize.
It should be noted that, under the instruction of this specification, any equivalents done by those skilled in the art, or obvious variant, all should within protection domain of the present utility model.
