Abstract

The utility model discloses a liquid tube net for a contrasting detection of standard flow meter and awaiting flow meter, which belongs to flow meter detecting field. The utility model comprises a water inlet pipe, an upper valve, a standard flow meter which is installed in a paralleling way, a lower valve, a water outlet pipe, etc. A standard flow meter which is installed in a series way is connected on a pipeline of two standard flow meters which are installed in a paralleling way. And the standard flow meter which is installed in a series way is connected with the lower valve of the former standard flow meter and the upper valve of the later standard flow meter. The utility model has the advantages that the detection is directly on the net pipe and the systematic error and the calibrating time are reduced and the precision of the device is increased. And the utility model can make a plurality of combinations and can detect standard flow meters with various apertures, which can enlarge the measuring range. Meanwhile, due to the reduction of the valve quantity the investment can be reduced.

Description

Liquid tube net
Technical field
The utility model relates to field of flow detection, the Liquid tube net structure of especially using proving flowmeter (or mark table) that detected flowmeter is compared and detected.
Background technology
The raising that quality of life is required along with growth in the living standard and the people, country controls also in continuous reinforcement the metering and the environmental protection total amount of pollutants discharged of water resource, for reaching the purpose of control, demand to the instrument of measuring flow also constantly increases, and is more outstanding to the imbalance between supply and demand of heavy caliber flowing meter especially.Existing water flow standard apparatus generally all exists investment big, and the maximum flow of test is little, does not satisfy the needs of producing far away.Adopt the way of proving flowmeter to be admitted by flow circle in the big water flow standard apparatus, on flow detector, utilize pipe network structure, also can form different calibers and make up the detection of comparing, but the proving flowmeter of prior art Liquid tube net adopts and is installed in parallel, before each proving flowmeter, back pipeline is equipped with upstream valve and valve downstream, can not directly compare between the proving flowmeter, detect because generally all proving flowmeter is placed on the other flow standard device, and then be installed on the Liquid tube net flowmeter that need are detected and detect, so just can't know and reinstall afterwards by proving flowmeter how many caused errors is.The existing defective of the parallel pipeline of former technology just is and can't compares detection mutually to proving flowmeter.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art and a kind of Liquid tube net that can directly compare detection to proving flowmeter on pipe network mutually is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: Liquid tube net, comprise water inlet pipe, upstream valve, the proving flowmeter that is installed in parallel, valve downstream, rising pipe, it is characterized in that connecing on the pipeline of adjacent two proving flowmeters that are installed in parallel a proving flowmeter that is installed in series, the two ends of this proving flowmeter join with the downstream of previous proving flowmeter and the upstream of a back proving flowmeter respectively.
Described upstream valve has NO1 valve, NO2 valve, NO3 valve.
Described normal flow is in respect of NO1 proving flowmeter, NO2 proving flowmeter, NO3 proving flowmeter, NO4 proving flowmeter, NO5 proving flowmeter.
Described NO2 proving flowmeter is connected between the upstream of the downstream of NO3 proving flowmeter and NO1 proving flowmeter; The NO4 proving flowmeter is connected between the upstream of the downstream of NO5 proving flowmeter and NO3 proving flowmeter.
Described valve downstream has NO4 valve, NO5 valve, NO6 valve.
Compared with prior art, directly comparison detects and calibration the utility model because proving flowmeter is connected on pipe network, avoids the relative alignment error between the proving flowmeter to take place, and reduces systematic error, shortens the alignment time to proving flowmeter; The parallel connection of proving flowmeter can constitute multiple combination, measures the flowmeter of multiple bore, comprises the flowmeter of the big flow of heavy caliber, has enlarged measurement range, has reduced the valve setting, can reduce investment; Also can improve the precision of device by the method that the range ratio of proving flowmeter is dwindled in employing.
Description of drawings
Accompanying drawing 1 has provided the utility model structural representation.
Embodiment
Embodiment describes in further detail the utility model in conjunction with the accompanying drawings.
Referring to Fig. 1, Liquid tube net comprises water inlet pipe, and the upstream valve that is connected water inlet pipe 1 end has NO1 valve 3, NO2 valve 4, NO3 valve 2.Be installed in normal flow in the pipeline in respect of NO1 proving flowmeter 13, NO2 proving flowmeter 12, NO3 proving flowmeter 5, NO4 proving flowmeter 7, NO5 proving flowmeter 6.Wherein NO1 proving flowmeter, NO3 proving flowmeter, NO5 proving flowmeter are installed in parallel in pipeline, NO2 12 proving flowmeters are connected between the upstream of the downstream of NO3 proving flowmeter 5 and NO1 proving flowmeter 13, and NO4 proving flowmeter 7 is connected between the upstream of the downstream of NO5 proving flowmeter 6 and NO3 proving flowmeter 5.The valve downstream that is connected pipeline rising pipe 10 ends has NO4 valve 11, NO5 valve 8, NO6 valve 9.
When the mutual comparison of carrying out proving flowmeter detects, just can compare to standard scale separately by odd number and even numbers with NO4 valve 11 as long as open NO3 valve 2, promptly NO1, NO3, the accurate flowmeter of NO5 three station symbols compare, and NO2 and NO4 proving flowmeter compare.Because when opening NO3 valve and NO4 valve, measured medium passes through NO1 successively, NO2, NO3, NO4, the NO5 proving flowmeter, according to the continuity principle of fluid as can be known, the flow of each flowmeter of flowing through is identical (Q1=Q2=Q3=Q4=Q5), and NO1, NO3, fluid flow direction in three proving flowmeters of NO5 is identical, NO2, fluid flow direction in two proving flowmeters of NO4 is identical, two groups flow to opposite, consider the influence that fluid flow direction detects flowmeter, these two groups of flowmeters can be compared respectively mutually, obtain alignment error and in detecting calibrated meter, eliminated, improved the accuracy of detection of equipment.
Owing to changed the mounting means of proving flowmeter in pipeline, valve quantity is reduced, the valve quantity of prior art: M valve=L * 2, L is the flowmeter number in the formula.
And the design's valve quantity: the M valve=(L-3)+4, L is 3,5,7,9 in the formula ... (being odd number).
For example: when L=5, the valve number of existing technology is 5 * 2=10, valve number (the 5-3)+4=6 of present technique, and as seen, valve quantity is saved 4.
When L=7, existing technology M valve=7 * 2=14
Present technique M valve=(7-3)+4=8 compares and saves 6 valves, so the equipment investment of this device is few.
