Abstract
The utility model discloses an ultra-wide-range gas metering device which comprises a main pipeline, a branch pipeline and a control valve driver. One end of the main pipeline is provided with a gas inlet and the other end of the main pipeline is provided with a gas outlet. The front end and the rear end of the branch pipeline are communicated between the gas inlet and the gas outlet of the main pipeline in a coiled mode respectively. The main pipeline is provided with a large-caliber flow meter and a main pipeline control valve. The branch pipeline is provided with a small-caliber flow meter and a branch pipeline control valve. The large-caliber flow meter and the small-caliber flow meter are both provided with flow signal output interfaces. The flow signal output interfaces are in input connection with the control valve driver. The control valve driver is in driving connection with the main pipeline control valve and the branch pipeline control valve. The ultra-wide-range gas metering device has the advantages that the requirement of a user for the ultra-wide metering range is met, meanwhile, the valves do not need to be opened or closed manually, and therefore the metering device is convenient to use.
Description
Technical field
The utility model relates to a kind of gas dosing device, specifically refers to a kind of super-wide range gas dosing device.
Background technology
Quickening along with popularization progress, use the user of rock gas constantly to increase, so how to solve use gas peak (more than several hectosteres per hour) and the measurement problem during with gas low ebb (several cubic metres of left and right per hour) has become the major issue that solution is badly in need of in combustion gas (air feed) department.At present, the maximum range Q of domestic and international all flowmeters
maxwith minimum range Q
minratio be all less than 30:1, cannot meet above-mentioned measuring requirement.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, and a kind of super-wide range gas dosing device that can meet user's super-wide range metering needs is provided.
Further arranging is for achieving the above object, the technical solution of the utility model is to include main pipeline, branch pipe(tube) and operation valve driver, one end of main pipeline is gas feed, the other end is gas vent, the rear and front end of this branch pipe(tube) is coiled respectively and is connect between the gas feed and gas vent that is communicated in main pipeline, on described main pipeline, be provided with for heavy caliber flowing meter and main line operation valve, on described bye-pass, be provided with small-caliber flow meter and bye-pass operation valve, on described heavy caliber flowing meter and small-caliber flow meter, be provided with flow signal output interface, this flow signal output interface is connected with the input of operation valve driver, this operation valve driver drives and is connected mutually with bye-pass operation valve with main line operation valve.
Further arrange is that the range of described heavy caliber flowing meter is 50-1000m
3/ h, the range of described small-caliber flow meter is 0.65-100m
3/ h.
Further arranging is that between the gas feed of described main pipeline and gas vent, counter offer is connected to the second branch road, is provided with the second branch road operation valve on this second branch road.
The utility model has the advantages that, utilize main line operation valve and bye-pass operation valve switching controls on main line and bye-pass, thus metering while making respectively the corresponding gas flow of heavy caliber flowing meter large, and hour metering of the corresponding gas flow of small flowmeter, its Q
