Description
Technical field
The utility model relates to a kind of flow measurement device, relates in particular to a kind of measurement mechanism that is used to measure fluid flow of wide-range.
Background technology
At present, the known device that is used for measurement gas, fluid flow is a flowmeter, but the range of conventional flowmeter is all smaller, also is that range ratio is less.For example mostly the range of conventional flowmeter is 8m
3/ h～100m
3/ h, 2m
3/ h～8m
3/ h or 0.5m
3/ h～2m
3/ h, the flowmeter of above-mentioned specification range can't satisfy the wide-range of some special operation conditions, the high-acruracy survey requirement; And some wide-range flowmeters are arranged also in the prior art; But these wide-range flowmeters are complex structure not only, and complicated operation costs an arm and a leg; And most importantly because range is big; Therefore how thereby can't reach satisfied measuring accuracy, a kind of wide-range of exploitation, high-precision Flow Measuring System on the basis of original technology are that those skilled in the art hope the technical matters that can solve.
Summary of the invention
The utility model provides a kind of wide-range flow measurement device, this device solves not only require wide-range but also require high-precision special measurement situation in some special operation conditions.
This wide-range flow measurement device of the utility model includes main line, branch road pipeline, flowmeter, controller and valve.Wherein main line has fluid intake and fluid egress point, and said main line is provided with at least one branch road pipeline, and the main line caliber is thicker, and the branch road pipeline originates near the fluid intake end of this main line, ends near the fluid outlet; Main line and branch road pipeline are provided with flowmeter, and the range of each flowmeter is all inequality, and the range of the caliber of each pipeline and its corresponding flow meter adapts; Also be provided with valve on each pipeline; Said valve and the said flowmeter that is arranged on each pipeline that is arranged on each pipeline all is connected in same controller; This controller is used to obtain the data of each flowmeter; And data are carried out computing and comparison, through computing and comparison, thus the duty of control respective line; Said flowmeter is arranged at each pipeline near fluid intake one side, and said valve is arranged at pipeline near fluid egress point one side.
In the actual conditions work, the initial state branch road is in closed condition automatically, has only main road to be in unimpeded state; When fluid passed through, the flowmeter that is arranged on the main line at first can record data, and said controller obtains these data; And the range of these data and this flowmeter is compared, if this value is in the range ability of this flowmeter, main line will be in running order always; If should be worth the range less than this flowmeter, controller can cut out the valve of main line automatically, and opens another other bypass line of range level simultaneously; Then, the flowmeter of bypass line obtains corresponding measured value, and this value is transmitted in controller; Controller is with the flowmeter range contrast of this numerical value and this branch road, if this value is in this range, then; This range is in running order always, in the process of work, if the data that controller obtains are suddenly greater than the range of this flowmeter; Then, controller cuts out the valve of this branch road automatically, and opens the valve than other pipeline of the high one-level of its range or main line simultaneously; In like manner, in the process of work, if the data that controller obtains suddenly less than the range of this flowmeter, then, controller cuts out the valve of this branch road automatically, and opens the valve than low other branch road pipeline of one-level of its range simultaneously.The working condition of other branch roads is identical with the working condition of aforementioned two pipelines.
Description through the above-mentioned course of work; Can know; The described this flow measurement device of the utility model; Utilize the flowmeter of different ranges under the control of controller, to cooperate, thereby realize the high-precision target of wide-range, solved special range and special range accuracy requirement under some special operation conditions.
Description of drawings
Fig. 1 is the structural representation sketch of the utility model one specific embodiment
Embodiment
For the architectural feature and the use principle of the utility model better are described,, a specific embodiment of the utility model is done further to specify below in conjunction with accompanying drawing.Specify as follows:
Fig. 1 is the structural representation sketch of a specific embodiment of the said wide-range flow measurement device of the utility model; As shown in the figure; Can know that the described wide-range flow measurement device of this embodiment includes a main line 1 and two branch road pipelines, be called the first branch road pipeline 2 and the second branch road pipeline 3 respectively; The first branch road pipeline 2 and the second branch road pipeline 3 all originate in the fluid intake place near main line 1, end at the fluid outlet near main line; It is 8m that said main line is provided with a range
3/ h～100m
3Flowmeter 11 and the valve 12 of/h; It is 2m that the said first branch road pipeline is provided with a range
3/ h～8m
3Flowmeter 21 and the valve 22 of/h; It is 0.5m that the said second branch road pipeline is provided with a range
3/ h～2m
3Flowmeter 31 and the valve 32 of/h; Three flowmeters all are arranged at separately, and pipeline is respectively applied for the flow size of measuring corresponding pipeline inner fluid separately near the place of inlet; Three valves all are arranged at the place that each pipeline is close to outlet, are used to control the duty of each pipeline, and when the valve open of corresponding certain pipeline, this pipeline belongs to on-state, and this pipeline is in running order; Said main line flowmeter 11, first flow meter 21, second flowmeter 31 all are connected in controller 4 with valve on said each pipeline.
In the real work; At first, the valve closing of two branch road pipelines, the branch road pipeline is in off working state; Get into main line 1 as fluid from inlet; The flowmeter 11 of main line at first obtains a measured value, and this value is sent in controller 4, and controller 4 is with the range 8m of this numerical value and main line flowmeter 11
3/ h～100m
3/ h compares, if this numerical value is in 8m
3/ h～100m
3Perhaps equal 8m among the/h
3/ h, then this main line 1 will continue in running orderly, if work a period of time, perhaps for some reason, the flow through main line 1 fluid descends, controller 4 obtains data from flowmeter 11, and with these data and 8m
3/ h～100m
3/ h compares, if these data are less than 8m
3/ h, controller control the valve 12 of this main line automatically and close, and trigger 2m simultaneously
3/ h～8m
3The valve 22 of/h pipeline, thus make the branch road of winning in running order, after work a period of time, if controller 4 is in 8m again from the data that the first branch road flowmeter 21 obtains
3/ h～100m
3/ h, then, controller 4 is readjusted, and closes the valve 22 of first branch road, trigger main line valve 12, and main line is in running order again; If controller is in 0.5m from the data that the first branch road flow 21 obtains
3/ h～2m
3/ h, then, controller is readjusted, and closes the valve 22 of first branch road, triggers the second branch road valve 32, and second branch road 3 is in running order.
After having used the described flow measurement device of this embodiment, the measurement of fluid flow range is brought up to present 0.5m by original little range
3/ h～100m
3/ h, range ratio is 200, and minimum measuring accuracy also with original 0.5m
3/ h～2m
3The measuring accuracy of/h range is identical, thereby has reached wide-range, wide range ratio, the function of high measurement accuracy.
The above only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the principle of the invention; Can also make some modification and improvement, these also should be regarded as belonging to protection scope of the present invention.
