Description
Technical field
The utility model relates to a kind of differential pressure flowmeter, a kind of inner cone flow meter of more specifically saying so.
Background technology
Traditional differential flow is counted orifice flowmeter, is widely used in the flow measurement of production processes such as oil, chemical industry, medicine, metallurgy, electric power.But, because defective such as orifice plate exists that crushing is big, range ratio is short, it applied significant limitation.State Intellectual Property Office's on January 12nd, 2005 disclosed " inner cone flow meter " (publication number: 2670916), the flowmeter of document introduction comprises flange, straight tube and cone, be arranged in the V-shaped taper of cone of straight tube, cone is connected with the negative pressure pressure pipe that stretches out straight tube, malleation pressure pipe is positioned at before the negative pressure pressure pipe, and cone is fixedly connected on the support bar by its pressure tappings.The mode that interior cone flow meter shrinks with the limit wall has replaced the mode of orifice plate center throttling, has avoided the sharp edge wear problem of orifice plate.Because what the cone afterbody produced is a kind of whirlpool of high-frequency low amplitude value, such signal can strengthen the performance of differential pressure transmitter, makes it to measure littler differential pressure, thereby range ratio is increased.Have the self-rectifying effect owing to cone simultaneously, so the convection cell velocity distribution is insensitive.Because these characteristics of cone flow meter make it become the product of the update of orifice plate in the V-arrangement, and obtain to use widely.
But this kind flowmeter need could use with other elements combination, because other element and interior prick flow transducer are respectively user's design and type selecting by each specialized factory, design department respectively, when the user buys above-mentioned component-assembled, often because of Product Renewal, the change of installation dimension produces that differential pressure transmitter does not cooperate with valve or transmitter such as can't fix at problem.In addition, disperse production also to improve acquisition cost.
The utility model content
At the problems referred to above, the problem that the utility model quasi-solution is determined provides a kind of compact conformation, easy for installation, production cost is low, measuring accuracy is high inner cone flow meter.
The purpose of this utility model, by adopting following technical proposals to realize: a kind of inner cone flow meter, comprise the cone-shaped body in straight tube and the straight tube, also be provided with malleation pressure pipe and negative pressure pressure pipe on the described straight pipe wall, described malleation pressure pipe is positioned at before the negative pressure pressure pipe, described negative pressure pressure pipe is connected with cone-shaped body, described inner cone flow meter is also organized into differential pressure transmitter and three valve groups, described three valve groups and malleation pressure pipe, negative pressure pressure pipeline connects, differential pressure transmitter is fixedlyed connected with the upper surface of the valve body of three valve groups, the malleation input port of differential pressure transmitter is connected with the malleation delivery outlet of three valve groups, and the negative pressure input port of differential pressure transmitter is connected with the negative pressure delivery outlet of three valve groups.
Above-mentioned inner cone flow meter, it can also be organized into two stay pipes, and described three valve groups are connected by two stay pipe pipelines respectively with negative pressure pressure pipe with malleation pressure pipe.
As improvement, inner cone flow meter of the present utility model also is provided with temperature sensor and pressure sensor.
Adopted such scheme, described inner cone flow meter is also organized into differential pressure transmitter and three valve groups, the problem of having avoided flowmeter could use with other elements combination, make inner cone flow meter product of the present utility model have compact conformation, easy for installation, production cost is low, the measuring accuracy advantages of higher.It is to confirm zero point and correction in order to be in operation that three valve groups mainly act on, and differential pressure transmitter upgrades when fault is arranged and is provided with.Group has been gone into temperature sensor and pressure transducer, the function of the flowmeter of Qiang Huaing more.
Description of drawings
Fig. 1 is an inner cone flow meter structural drawing of the present utility model.
Among the figure: 1-differential pressure transmitter, 2-three valve groups, 3-stay pipe, 4-straight tube, 5-cone-shaped body, 6 malleation pressure pipes, 7-negative pressure pressure pipe, 8-pressure sensor, 9-temperature sensor.
Embodiment
As shown in Figure 1, inner cone flow meter of the present utility model, comprise the cone-shaped body 5 in straight tube 4 and the straight tube 4, also be provided with malleation pressure pipe 6 and negative pressure pressure pipe 7 on described straight tube 4 walls, described malleation pressure pipe 6 is positioned at before the negative pressure pressure pipe 7, described negative pressure pressure pipe 7 cone-shaped bodys 5 are connected, and it is consistent that these structures and background technology are introduced, and therefore no longer launch to describe.Characteristics of the present utility model mainly are that group has been gone into differential pressure transmitter 1 and three valve groups 2, described three valve groups 2 are connected with malleation pressure pipe 6, negative pressure pressure pipe 7 pipelines, differential pressure transmitter 1 is fixedlyed connected with the upper surface of the valve body of three valve groups 2, the malleation input port 6 of differential pressure transmitter 1 is connected with the malleation delivery outlet of three valve groups 2, and the negative pressure input port 7 of differential pressure transmitter 1 is connected with the negative pressure delivery outlet of three valve groups 2.Described three valve groups are connected by two stay pipe 3 pipelines respectively with negative pressure pressure pipe 7 with malleation pressure pipe 6.
In order to obtain flow measurement curve preferably, the differential pressure transmitter that requires to be joined has higher precision and repeatability, such as 1151,3051 serial differential pressure transmitters.The main consideration of the selection of three valve groups cooperates with differential pressure transmitter and straight tube, and will carry out air tightness test, with anti-gas-leak.
Also be provided with pressure transducer 8 and temperature sensor as improving in the described straight tube 4.
The three valve groups 2 of installing on the utility model, main effect are to confirm zero point and correction in order to be in operation, and differential pressure transmitter upgrades when fault is arranged and is provided with.
When inner cone flow meter of the present utility model uses, differential pressure transmitter 1, pressure transducer 8 and temperature sensor are connected with control device, can obtain the information such as flow, pressure, temperature of straight tube inner fluid.
