Abstract
The utility model discloses a metering device with a wide measuring range, which comprises a flow meter, a water inlet pipe, a water outlet pipe, a control valve, a water inlet pipe three-way connector, a water outlet pipe three-way connector, an auxiliary water inlet pipe, an auxiliary water outlet pipe, an auxiliary flow meter and an auxiliary control valve. The water inlet pipe is connected with the water inlet pipe three-way connector which is respectively connected with the flow meter and the auxiliary water inlet pipe. The auxiliary water inlet pipe is successively connected with the auxiliary flow meter, the auxiliary control valve, the auxiliary water outlet pipe and the water outlet pipe three-way connector. The flow meter is successively connected with the control valve, the water outlet pipe three-way connector and the water outlet pipe. The metering device with the wide measuring range can respectively improve metering accuracy aiming at the situation that when the flow fluctuates, large flow automatically chooses the flow meter with large measuring range and small flow automatically chooses the auxiliary flow meter with small measuring range. The metering device with the wide measuring range has simple structure, is convenient to operate and can be applied to occasions with various flow ranges.
Description
Technical field
The utility model relates to a kind of gas-liquid flow measurement device, more particularly relates to the very big wide-range measuring apparatus of a kind of suitable flow range fluctuation.
Background technology
The application of present flow measurement device is very extensive, and we can use the measuring apparatus of different ranges at different big or small flows, and we use the device of little range for low discharge, can the result of metering is more accurate; Big flow uses the device of wide range, and its possibility of result can be than a small amount of range device out of true, but range is bigger.Therefore we the metered flow fluctuation very big gas-liquid the time unusual trouble just, may no to scale with journey measuring apparatus in a small amount, may be with the wide range measuring apparatus in flow hour result out of true very, very inconvenient to gage work like this.
Summary of the invention
In order to address the above problem, the utility model provides a kind of wide-range measuring apparatus, by threeway flowmeter in parallel and auxiliary flow meter, can the big gas-liquid of metered flow fluctuation range, only use the less auxiliary flow meter of range during low discharge, only use the bigger flowmeter of range during big flow, so just solved that flowmeter can not the big trouble of metered flow fluctuation range in the past.
The utility model specifically is achieved through the following technical solutions:
A kind of wide-range measuring apparatus, comprise flowmeter, water inlet pipe, rising pipe, operation valve, water inlet pipe three-way connection, rising pipe three-way connection, auxiliary water inlet pipe, auxiliary rising pipe, auxiliary flow meter and aux. control valve, described water inlet pipe connects a water inlet pipe three-way connection, and described water inlet pipe three-way connection is connection traffic meter and auxiliary water inlet pipe respectively; Described auxiliary water inlet pipe connects auxiliary flow meter, aux. control valve, auxiliary rising pipe and rising pipe three-way connection successively; Described flowmeter connects operation valve, rising pipe three-way connection and rising pipe successively.
Described flowmeter connects operation valve by a valve driving line, and described auxiliary flow meter connects aux. control valve by another root valve driving line;
Described flowmeter is connected by interface signal line with the auxiliary flow meter;
The Inlet and outlet water bore of described flowmeter is greater than the Inlet and outlet water bore of auxiliary flow meter;
The range upper limit of described flowmeter is greater than the range upper limit of auxiliary flow meter, and the range lower limit of flowmeter is less than the range upper limit of auxiliary flow meter.
Can be respectively at flow rate fluctuation the time, big flow be selected the big flowmeter of range to the utility model automatically, selects the little auxiliary flow meter of range to improve the accuracy of metering during low discharge by threeway flowmeter in parallel and auxiliary flow meter.This apparatus structure is simple, easy to operate, can satisfy the metering occasion of various flow range.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Be illustrated in figure 1 as structural representation of the present utility model, a kind of wide-range measuring apparatus, comprise flowmeter 3, water inlet pipe 1, rising pipe 6, operation valve 5, water inlet pipe three-way connection 2, rising pipe three-way connection 4, auxiliary water inlet pipe 7, auxiliary rising pipe 10, auxiliary flow meter 8 and aux. control valve 9, described water inlet pipe 1 connects a water inlet pipe three-way connection 2, and described water inlet pipe three-way connection 2 is connection traffic meter 3 and auxiliary water inlet pipe 7 respectively; Described auxiliary water inlet pipe 7 connects auxiliary flow meter 8, aux. control valve 9, auxiliary rising pipe 10 and rising pipe three-way connection 4 successively; Described flowmeter 3 connects operation valve 5, rising pipe three-way connection 4 and rising pipe 6 successively.
Above-mentioned flowmeter 3 connects operation valve 5 by a valve driving line 11, described auxiliary flow meter 8 connects aux. control valve 9 by another root valve driving line, described flowmeter 3 is connected by interface signal line 12 with auxiliary flow meter 8, can control the unlatching of operation valve 5 and aux. control valve 9 respectively or closes by flowmeter 3 and auxiliary flow 8 like this.Because flowmeter 3 connects the data on flows that can read water inlet pipe on 8, two flowmeters of auxiliary flow meter by interface signal line 12, further confirm the reading of auxiliary flow meter 8 and flowmeter 3 simultaneously.
Wherein the Inlet and outlet water bore of flowmeter 3 is greater than the Inlet and outlet water bore of auxiliary flow meter 8, the range upper limit of flowmeter 3 is greater than the range upper limit of auxiliary flow meter 8, the range lower limit of flowmeter 3 is less than the range upper limit of auxiliary flow meter 8, guaranteed that flowmeter 3 always can measure the gas-liquid flow bigger than auxiliary flow meter 8.
When device of the present utility model was zero flow at water inlet pipe 1, flowmeter 3 drove closed control valve 5 by valve driving line 11, and this moment, auxiliary flow meter 8 driving aux. control valves 9 were opened, and were in waiting status.When auxiliary flow meter 8 have flow by and the flow that passes through be lower than on its range in limited time, auxiliary flow meter 8 can measure flow; When the flow in the auxiliary flow meter 8 surpassed range ability, 8 pairs of flowmeters 3 of auxiliary flow meter sent signal, and flowmeter 3 drive control valves 5 are opened, and aux. control valve 9 is closed simultaneously, and this moment, flowmeter 3 and auxiliary flow meter 8 were finished the one action switching.When the flow in the flowmeter 3 was lower than its range, in like manner, operation valve 5 was closed, and aux. control valve 9 is opened, auxiliary flow meter 8 beginning metered flow sizes.Because the range lower limit of flowmeter 3 has certain threshold values less than the range upper limit of auxiliary flow meter 8 between such two flowmeters, can effectively avoid frequent switching between the two.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
