Description
Technical field
What the present invention relates to is a kind of device of fluid measurement technical field, and specifically a kind of X-shape of α structure divides interflow device and two vibrating tube coriolis mass flowmeters thereof.
Background technology
Coriolis (Corioli is called for short Coriolis) mass flowmeter is because Coriolis effect causes the vibration phase difference of vibrating tube both sides, to carry out the detection of mass rate while utilizing fluid to flow through vibrating tube.For high-precision measurement, conventionally adopt twin elbow (or claim: " two measuring tube " or " two vibrating tube ", lower with) form.In published patent, its pipeline structure is from inflow entrance/pipe to shunt to measuring tube, then to interflow device (being another shunt), again to flow export/pipe, all adopted symmetric figure design from measuring tube.Wherein adopt the design of annular, U-shaped and triangulation pipe, fluid must approach or be more than or equal to 90 ° " flowing curved " from flowing to mouth/pipe by flowing to angle to measuring tube.From measuring tube to flow export/pipe need be again by symmetric design " flowing curved ".Cause thus the pressure loss of fluid (to be called for short: crushing) rise, and then cause the decline of transfer efficiency and reach not being loaded effectively fully loaded pressure requirement of container.
Also the coriolis flowmeter that has Straight, minor bending and several fonts, its import and export/pipe is less than or equal to 90 ° with the angle that flows to of measuring tube, is even 0 ° of degree.But this class formation can cause flowmeter import and export to connect the problems such as (claiming again process joint) mounting distance is large, measuring tube resonance frequency is high, measure sensitvity constraint, interference free performance is not good enough, technical requirement on design is high.
With social development, the demand of high precision flow is obviously risen.Existing a lot of the patents of twin elbow formula coriolis flowmeter widespread use.Significantly lifting with the whole world to compressed natural gas and liquefied natural gas (LNG) consumption, synchronously rises to low pressure loss, high-precision flowmeter demand, and the excessive problem of crushing that some commodity causes due to structural design has started to expose.Therefore, develop the low pressure loss coriolis flowmeter of new shape structure, to meet the demand of China and even global economy development, extremely meaningful.
Cause the excessive reason of flowmeter crushing to mainly contain, the arm after shunting (containing measure pipeline section and with a minute overall length for the linkage section of interflow device) long pipe friction resistance excessive and curved flow through many and each curved stream to flow to angle excessive and cause.The fact shows: to there being low pressure loss requirement flow system, the flowmeter that crushing is large will be restricted.For example, certain adopts the coriolis flowmeter of Ω shape, and because crushing is large, having confirmed cannot be for LNG(liquefied natural gas (LNG)) liquid feeding (gas) machine.
Warp is to there being now the literature search of technology to find, Chinese patent literature CN1764827, discloses a day 2006-04-26, discloses a kind of double u-tube coriolis mass flowmeters, comprising: at least one flow-catheter; The drive system being connected with this at least one flow-catheter; The balanced system being connected with this at least one flow-catheter.In this technology, two vibrating tube are made into " U " font, two vibrating tube are fixed by fixed head, and be welded on total tube body, total tube body is the physical construction of a complete reverse symmetry of input and output, 4 ends of two vibrating tube are very little with the distance that total tube body is connected, and its flow direction of house steward and vibrating tube is 90 ° of angles.
Chinese patent literature CN1335934, open day 2002-02-13, discloses a kind of small dimension coriolis flowmeter of measuring for large mass, can process large mass velocity, and have tick marks size.In order to reduce label size, flowtube (103A-103B) forms an arc (150) for semicircle substantially between entrance and exit.Back up pad (120-121) is installed in flowtube near entrance and exit place, to separate the vibration frequency of flowtube.Sensing detection device (105-105 ') is installed on the cardinal principle semi arch (150) of flowtube.This technology mainly comprises two semicircular vibrating tube, and 4 ends of two vibrating tube are connected with total tube body by 2 shunts, and its of house steward and vibrating tube flows to angle and be 90 °.
Chinese patent literature CN1371468, open day 2002-09-25, discloses the type identification that a kind of driving for coriolis flowmeter is controlled, and will initially drive signal to add to the driving circuit that (401) make flow tube vibration.Then, the signal receiving according to the pickoff sensor from being associated with flow tube, the structure of definite (404) flow tube.According to the structure of flow tube, the parameter that (405) are used for producing described driving signal is set.4 ends of two vibrating tube of this technology are connected with total tube body by 1 single casting part combined shunting device, and its of house steward and vibrating tube flows to angle and be 135 °.
U.S. Patent number US7,340,964B2, open day 2008-03-11, the large flow Ke Liao of a kind of Coriolis mass flow meter(flowmeter is disclosed), entry date 11/1988, authorization date, Mar.11,2008, this patent is only established the circuit design relating to after shunting, as considers upper shunt and house steward, the angle that flows to of its house steward and vibrating tube is 135 °, and the invalid tubule path after shunt is very long.Above-mentioned technology is representational, and house steward and its near-end vibrating tube flows to generally all >=90 ° of angles.
American documentation literature US4,984,472, authorize a day 1991-01-15, a kind of APPARATUS FOR MASS FLOW RATE AND DENSITY MEASUREMENT(flux density measurement mechanism is disclosed), but this technology shunt is plane symmetry structure and is positioned at same level, adopt divide/confluent structure of variform Y tube directly to cause its pipeline section longer, on supervisor's axis, realize a minute interflow makes the distance of process joint also longer simultaneously, such general structure causes that its crushing is large and testing result is inaccurate, is difficult to use in effective measurement.
