Description
Technical field
The utility model relates to a kind of measurement mechanism of pipeline inner fluid flow, a kind of specifically Flow Measurement Display Meter.
Background technology
At present, flowmeter extensive application in active procedure control.Particularly in industries such as metallurgy, oil, chemical industry, thermoelectricity, how a large amount of fluid pipeline pipe networks finds out the earial drainage point fast through for many years use burn into leakage phenomenon, becomes and carries out the pipeline maintenance, guarantees the key of the normal operation of pipeline.
Cooling system, heating system etc. are by comprising that a series of cooling duct that has that house steward is in charge of constitutes the loop, present flowmeter price comparison costliness, generally respectively install one at the import export of system, intelligence is measured system and is had leakage, but can not determine it is which segment pipe exists leakage, the method efficient of pipe inspection is very low one by one, and maintenance mans' workload is very big.
Traditional flow meter applications search in cooling system, heating system earial drainage point application have a price height, general unit holds dares not accept, and can not promote on a large scale.Conventional flow indicator uses the right-angle baffle structure, and spring reset, right-angle baffle cause that the pressure loss is big, and rotating shaft need be lubricated, and the indication of baffle plate flow is not linear, and measuring error is big, and poor durability is observed difficulty, is not easy to judge the shortcoming of flow percentage.Through use after a while, the spring reset of spring reset can stress fatigue, and flexibility decrease causes the indicated value of flow indicator inaccurate, makes the judgement of maintenance mans' mistake think that pipeline reveals easily, actual just spring fatigue and causing.Common right-angle baffle can only reach about 80% of pipeline drift diameter circulation area when flow is maximum, increased the pressure loss greatly, has wasted the energy.And the aperture of common right-angle baffle and flow only approach linear relationship in very little scope, and the observation measurement range of the flow indicator that makes is smaller.
Summary of the invention
The technical problems to be solved in the utility model, be exactly to solve conventional flow indicator to use the linear bad measuring error of right-angle baffle structure big, use the spring reset poor durability, right-angle baffle causes that the pressure loss is big, rotating shaft need be lubricated, the indication of baffle plate flow is not linear observation difficulty, is not easy to judge the shortcoming of flow percentage.Provide a kind of observation simple, show according to the equal percentage indication, do not need spring reset, simple in structure, volume is little, and installation is convenient, and applicability is wide, broad quantum, and antidetonation, good endurance, high temperature resistant, crushing is little, novel Flow Measurement Display Meter.
The following technical scheme of the concrete employing of the utility model:
A kind of Flow Measurement Display Meter, by flow view window, view window can, equal percentage indicating graduation, rated flow be provided with pointer, instantaneous delivery pointer, zero-bit lower edge base, centre rotational axis, inlet honeycomb duct, outlet mozzle, lining mould sealing ring, from gravity indicator board, limiting bracket, constitute from gravity balancing weight, flange, it is characterized in that, inlet honeycomb duct links to each other with the entrance and exit of outlet mozzle respectively at liquid pipeline system, make fluid enter Flow Measurement Display Meter, flow out Flow Measurement Display Meter by the outlet mozzle by the inlet honeycomb duct place; Hang in the mozzle by the centre rotational axis installation from the gravity indicator board, and keep synchronously with the instantaneous delivery pointer; The equal percentage indicating graduation is labeled on the shell of Flow Measurement Display Meter view window, and rated flow is provided with pointer outside the view window can, and rated flow can manually be set.
When Flow Measurement Display Meter is not worked, the instantaneous delivery pointer because and from gravity indicator board, synchronous from the gravity balancing weight, under the action of gravity of gravity balancing weight, inlet honeycomb duct must be entered the mouth to be covered; During work, liquid enters inlet honeycomb duct, and its pressure surpasses the pressure from the gravity balancing weight, and liquid stream is washed open from the gravity indicator board, is its opened with certain angle, the size of this angle and the flow of liquid, and flow velocity, the size of pressure becomes the equal percentage relation.After the work beginning, current are washed the indicator board of demonstration open, make its opened with certain angle, the rotation rated flow is provided with pointer, aim at the equal percentage indicating graduation on the flow view window, determine ratings, during Flow Measurement Display Meter work later on, if it is consistent that instantaneous delivery pointer and rated flow are provided with pointer, then show working properly, if the instantaneous delivery pointer is provided with the pointer value of setting less than rated flow, show that then this pipeline has leakage, each loop all is provided with and installs 1 in whole liquid fluid system, just can know the working condition in each loop accurately, maintenance maintenance easily; When pipeline fluid no longer flows, can cover inlet honeycomb duct by return from the gravity indicator board, the fluid of whole pipeline can not flow backwards.
The utility model has the advantages that:
When the utility model uses, according to the long-pending pressure change calculations of measuring of fluid variable cross section in the pipeline, the circulation area that assurance from the gravity indicator board in unlatching is and the anglec of rotation be transformed into direct ratio, the parabolic fillet of particular design on the gravity indicator board, be equipped with through calculating from the gravity balancing weight, special shape can guarantee that the indicator board aperture in circular pipe keeps equal percentage to concern with flow in very big flow range.Improved the precision of the indication of flow greatly.Through the check of flow check device, precision can reach ± 3% in, flow measurement range is expanded more than 50%.The precision measure performance is better than like product greatly.Observe simply, show that gravity is from resetting according to the equal percentage indication, simple in structure, volume is little, and installation is convenient, and applicability is wide, broad quantum, and antidetonation, good endurance, high temperature resistant, crushing is little, novel Flow Measurement Display Meter.Be applicable to and in the pipeline that is installed on various different tube diameters various media carried out fluid measurement.
