Description
Technical field:
The present invention relates to a kind of extensively metering device of industry closed conduct conducting liquid flow measurement such as oil, chemical industry that is used for.
Background technology:
Oil, chemical industry etc. extensively industry need to adopt conducting liquid flow instrument that the flow of actuating medium in its closed conduct is measured in the production run process.At present, the on-the-spot conducting liquid flow meter structure more complicated of using, and inner chamber is provided with back boxing and rotatable parts, cost of manufacture height not only, processing difficulties, and blocked portion takes place in the utilization and operation process easily, influence the ordinary production and the operation of liquid flow mearuement and plumbing installation.The electric rotating flowmeter inner chamber no-rotary part that research and development are in recent years used has solved the blocked portion problem, but structurally dismounting is still convenient inadequately, requires further improvement.
Summary of the invention:
The object of the invention be to provide a kind of simple in structure, be easy to make, installation and maintenance plug-in type electromagnetic vortex flowmeter easily.
The present invention seeks to realize like this.This kind flowmeter comprises integrating instrument, core body and connector three parts, and integrating instrument is connected the core body top, and core body bottom plug-in type is assembled in the connector, and is connected to a fixed with bolt.Wherein, core body is made up of upper prepared cap, sensor, upper press cover, poly-tetrafluoro sheath, probe, poly-tetrafluoro overcoat, eddy flow generation body, magnet steel, lower prepared cap, lower cover, check nut, bracing frame, main body and O-ring seal, be provided with bracing frame in the main cavity, be provided with probe in the bracing frame mesopore, on the probe, the middle part outside is set with upper and lower two poly-tetrafluoro sheaths, tighten with screw thread and bracing frame with check nut the upper jacket top, and the outside, bottom is set with poly-tetrafluoro overcoat, and is provided with O-ring seal; Probe lower end cross through hole one face down bonding is connected to eddy flow generation body in the main body; The main body upper end is connected with upper press cover by nut, is provided with sensor in the upper press cover, and the upper end is with the upper prepared cap that has been threaded; In the main body periphery seal groove O-ring seal is housed, the lower end internal thread is connected with lower cover, and periphery is provided with magnet steel with the lower prepared cap that has been threaded in the cavity of lower cover top.During assembling, integrating instrument tipping above core body, is inserted the core body bottom in vertical mesopore of its below connector, and with bolt the two is connected and fixed and is one.During use, this flow instrument is installed on the conducting liquid actuating medium pipeline, the both sides ring flange is fixed with bolt, can devote oneself to work.During work, after conducting liquid is flowed through connector, produce vortex in eddy flow generation body back, vortex quantity is directly proportional with flow rate of liquid within the specific limits.Because magnet steel produces magnetic field herein, conducting liquid this magnetic field of flowing through, based on the vortex street principle of electromagnetic induction, probe just can receive pulse signal.This pulse signal becomes electric signal after sensor is handled, electric signal demonstrates the instantaneous value and the accumulated value of conducting liquid flow after integrating instrument is handled.Because adopted the special seal structure vertical, that transverse sealing combines, this flowmeter is applicable to hyperbaric environment.
The present invention is reasonable in design, novelty simple in structure, reliable operation, owing to adopted the core body plug in construction, be convenient to processing and manufacturing and installation and maintenance, utilize it can obtain good effect in conducting liquid flow gage work, this kind flowmeter also has broad quantum, precision height, corrosion-resistant, advantage such as application is wide.
