Abstract
A multi-runner Coriolis mass flowmeter sensor fluid main part comprises flow pipes, a support pipe, distribution bodies and connecting flanges. Two ends of each flow pipe are respectively fixedly connected to one sides of the distribution bodies. The other sides of the distribution bodies are fixedly connected with the connecting flanges. The support pipe is fixed between the two distribution bodies. The multi-runner Coriolis mass flowmeter sensor fluid main part is characterized in that the flow pipes are U-shaped and divided into an upper group and a lower group. Every two flow pipes form one group. Each group of flow pipes is of the same shape. The outer walls of two inclined straight pipes on two sides of each group of flow pipes are jointly fixedly provided with at least one damping plate. Compared with the prior art, the multi-runner Coriolis mass flowmeter sensor fluid main part has the advantages that the defects of currently-popular mass flowmeters are overcome, and the multi-runner Coriolis mass flowmeter sensor fluid main part is low in pressure loss, simplified in structure, high in flexibility, less prone to environmental influence, and the like.
Description
Technical field
The present invention relates to a kind of mass flow meter sensor, particularly the fluid main part in a kind of multiple flow passages type coriolis mass flowmeters sensor.
Background technology
Coriolis mass flowmeters (hereinafter to be referred as Coriolis flowmeter) is in flowtube synchronous vibration, in fluid ingress pipe, makes it along flowing forward in pipe, and body will force fluid up-down vibration therewith.Fluid is in order to revolt this forced vibration, can be to reacting force vertical with its flow direction of body, under the effect of this being called " Coriolis effect power ", the vibrations of body are asynchronous, its entrance pipe and outlet section pipe there will be difference on the time order and function of vibration, and this species diversity is directly proportional to the size of the fluid mass flow that flows through body.Go out the difference size of this time by electric circuit inspection, just can determine the size of mass rate.
Coriolis flowmeter is divided into two kinds of straight pipe type and bent tube types by flow cast, is divided into single tube and double-tube type by flowtube quantity.Straight pipe type is single tube or two-tube flowtube expanded by heating and the change of pressure of all existing, the strain causing is difficult to compensation, cause the reproducibility error of straight pipe type sensor very large, accuracy of instrument is reduced, the occasion even changing greatly at working temperature and pressure cannot be applied.Bent tube type divides the forms such as U, Δ, Ω, simple helix pipe, and Δ, Ω, simple helix Guan Yinqi inside lock is large or pipeline section is many, and build-up of pressure loss is large, is therefore shaped difficult, and range is little, seldom selected; And mostly at present popularly U-shapedly be two-tube, and but also because existing the pressure loss larger, at the bottom of frequency of operation, the defect such as volume is large, precision is on the low side.
Summary of the invention
Technical matters to be solved by this invention is to overcome existing defect in above-mentioned prior art, fluid main part in a kind of coriolis mass flowmeters sensor of multiple flow passages type is provided, make it both overcome the shortcoming of straight pipe type, there is very large improvement with respect to other bent tube types again, can significantly reduce volume, and improve precision.
The present invention has adopted following technical proposal to solve its technical matters: a kind of multiple flow passages type coriolis mass flowmeters sensor fluid main part, comprise flowtube, stay pipe, shunting body, joint flange, the two ends of flowtube are fixedly connected with respectively shunting body one side, this shunting body opposite side is fixedly connected with joint flange, in the middle of two shunting bodies, be fixedly equipped with stay pipe, it is characterized in that: described flowtube is U-shaped, be divided into upper and lower two groups, every two is one group, every group of shape is identical, and be jointly fixedly equipped with respectively at least a slice damping sheet on two inclination straight tube outer walls of every group of flowtube both sides.
The present invention compared with the existing technology, solves and overcomes at present popular mass flowmeter shortcoming, has the pressure loss little, and designs simplification is highly sensitive, the advantage such as little affected by environment.
Brief description of the drawings
Fig. 1 is sectional structure schematic diagram of the present invention;
Fig. 2 is perspective view of the present invention.
In figure, each sequence number is expressed as:
The upper flowtube of 1-; The dirty buret of 2-; 3-damping sheet; 4-shunting body; 5-stay pipe; 6-joint flange.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
See figures.1.and.2, the present invention includes flowtube, stay pipe 5, shunting body 4 and joint flange 6.
Described flowtube is U-shaped micro-bend pipe, and every two is one group, and every group of shape is identical.Two groups of flowtube are upper and lower installation, are divided into upper and lower two groups, go up flowtube 1 and dirty buret 2.Flowtube 1 and dirty buret 2 on this, the angle that the center line between its horizontal pipe and tilted tube forms is 115 degree, and the bending for seamlessly transitting between horizontal pipe and tilted tube.
On two inclination straight tube outer walls of described upper flowtube 1 and the both sides of dirty buret 2, be jointly fixedly equipped with respectively at least a slice damping sheet 3.The present embodiment is jointly fixedly equipped with respectively at least two damping sheets 3 on two inclination straight tube outer walls of both sides.Described damping sheet 3 be shaped as rectangle.
These shunting body 4 opposite sides are fixedly connected with joint flange 9, in the middle of two shunting bodies 4, are fixedly equipped with stay pipe 5, and this stay pipe 5 can also play protection flowtube work and the extraneous effect of interfering of shielding.
When the present invention works, fluid is through a side shunting body 4, arrive again opposite side shunting body 4 through upper flowtube 1 and dirty buret 2, the position distribution of damping sheet 3 effectively damping the vibration of flowtube, shunting body 4 is vibrated and do not produce the letter interference of making an uproar, also make extraneous vibration disturb and be not easy to pass to excitation system, thereby affect measuring accuracy.The present invention overcomes the impact that pressure changes, and improves precision and repeatability.
