Description
Technical field
What the utility model was related is a kind of flow measurement device, be specifically related to be a kind of measure conductive fluid can onlinely separate verification magnetoelectricity swirl flowmeter, can be widely used in the flow metering and the control in fields such as oil, chemical industry, be particularly useful for the metering of high oil field water injection station and water injection well clear water, sewage.
Background technology
The electromagnetic flowmeter of present industrial flow measurement application and vortex shedding flow meter have obtained general application, wherein vortex shedding flow meter is made according to the Karman vortex street principle, and electromagnetic flowmeter is made according to Faraday's electromagnetic induction law, but the shortcoming of vortex shedding flow meter is a poor anti jamming capability, degree of accuracy and accuracy are not too high, though and electromagnetic flowmeter precision height, but the cost of manufacture height costs an arm and a leg.And the sensor of traditional flowmeter all adopts global design with the table body, when needs to the verification of flowmeter cycle with when safeguarding, people must pull down whole flowmeter from pipeline, be transported to then to carry out verification and maintenance on the caliberating device worktable.Therefore, concerning the user, using traditional flowmeter to exist when safeguarding to remove and install to transport wastes time and energy and dismounting can cause the shortcoming such as loss that stops production of stopping.
Summary of the invention
The purpose of this utility model is to be deficiency that overcomes traditional flowmeter and shortcoming, provide that a kind of dismounting is simple, easy to maintenance, stable performance, long service life can onlinely separate verification magnetoelectricity swirl flowmeter.
The purpose of this utility model is achieved through the following technical solutions: can onlinely separate verification magnetoelectricity swirl flowmeter and comprise the table body that is connected with pipeline, flow conversion display instrument, connecting link, the inner chamber of described table body is provided with sensor unit, described sensor unit is by bottom, O shape circle, magnet, triangular prism, the detecting electrode parts, contain the core body of measuring the runner hole, gland, screw, the electrode block is formed integral structure, the bottom of described core body is provided with the magnet of closely being pushed down by bottom, described triangular prism is set at the left side that core body is measured the runner hole, be provided with the detecting electrode parts that are positioned at directly over the magnet in the measurement runner hole of described core body, by the screw on the gland sensor unit closely is pressed on the table body, the bottom of described connecting link is connected with sensor unit, and its top is connected with flow conversion display instrument.The runner hole of described table body is long straight-through circular hole design.The described core body that closely contacts with table body inner hole wall is provided with a plurality of O shape circles.
Compared with prior art, the beneficial effects of the utility model are:
(1) because the sensor unit that links to each other with flow conversion display instrument is designed to detachable structure with the table body, when using so at the scene, only needing that sensor unit is separated the table body safeguards just passable separately, and need not be from whole flowmeter of pipeline dismounting, can also accomplish not stop production and carry out, so when flowmeter being carried out the cycle verification and safeguarding, both alleviated labour intensity, improved work efficiency again.
(2) because measuring tube runner of the present utility model adopts straight-through design, effectively increased the length of front and back straight lengths, guaranteed the stability of media flow, and few easy workout part, so complete machine stability is good, maintenance cost is low.
(3) because core body is provided with a plurality of O shape circles, cut off seepage and the erosion of measuring media fully, so prolonged the serviceable life of complete machine to sensor unit.
Description of drawings:
Accompanying drawing is a structure cut-open view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Can onlinely separate verification magnetoelectricity swirl flowmeter designs and produces according to Karman vortex street and Faraday's electromagnetic induction law principle of combining, when MEDIA FLOW is crossed triangular prism, produce vortex alternately in triangular prism two rear flank, vortex is made cutting magnetic line movement in magnetic field, produce the electromagnetic induction pulse signal, in certain reynolds number range, velocity of medium is directly proportional with pulsed frequency.Pulse signal is through processing and amplifying, and conversion is shown as instantaneous delivery and accumulation total amount, and current signal output is arranged, and this type of flowmeter instrument is fit to measure nonmetallic conducting liquid.
Referring to accompanying drawing, the utility model comprise the table body 1 that is connected with pipeline, flow conversion display instrument 4, connecting link 3 and by bottom 2-1, O shape circle 2-2, magnet 2-3,, the parts such as sensor unit 2 formed of triangular prism 2-4, detecting electrode parts 2-5, core body 2-6, gland 2-7, screw 2-8, electrode block 2-9.The inner chamber of described table body 1 is provided with sensor unit 2, described sensor unit 2 is by containing the core body 2-6 that measures the runner hole, O shape circle 2-2, magnet 2-3, bottom 2-1, detecting electrode parts 2-5, triangular prism 2-4, gland 2-7, electrode block 2-9, screw 2-8 forms integral structure, the bottom of described core body 2-6 is provided with the magnet 2-3 that is closely pushed down by bottom 2-1, described triangular prism 2-4 is placed in the left-hand portion that core body 2-6 measures the runner hole, be provided with the detecting electrode parts 2-5 that is positioned at directly over the magnet 2-3 in the measurement runner hole of described core body 2-6, by the screw 2-8 on the gland 2-7 sensor unit 2 closely is pressed on the table body 1, the bottom of described connecting link 3 is connected with sensor unit 2, and its top is connected with flow conversion display instrument 4.The runner hole of described table body 1 is long straight-through circular hole design.The described core body 2-6 that closely contacts with table body 1 inner hole wall is provided with a plurality of O shape circle 2-1, can cut off seepage and the erosion of measuring media to sensor unit 2.
