Description
Technical Field
The present invention relates to a coriolis mass flowmeter, and more particularly, to a removable housing device of a coriolis mass flowmeter.
Background
Currently, the coriolis mass flowmeter has become a flow meter with the most precise accuracy in flow measurement, and the accuracy of a general flow meter is as follows: the liquid (water or oil) measures 1 and 0.5 grades and the gas measures 1.0 and 1.5 grades. Coriolis force mass flowmeters can be accurate to liquid measurements on the order of 0.1 and 0.2 and gas measurements on the order of 0.2 and 0.3. And no movable or rotary part is arranged in the whole measuring circulation pipeline, the operation can be reliable for a long time, the requirement on a measured medium is low, and the requirement on front and rear straight pipe sections of a measuring pipeline is low. Coriolis force mass flowmeters are rapidly and extensively used in a variety of industrial and utility applications. At present, the coriolis force mass flow meter adopts a totally-enclosed design, i.e., a closed shell is directly welded on a supporting tube, a flow measuring tube, which is a main part for measurement, is closed in the supporting tube, and a driving coil (for starting initial vibration), a detecting coil (for detecting a flow signal), a connecting wire, a damping plate, a balancing weight and the like are all arranged on the flow measuring tube. The flow measuring tube is brazed to the branch fluid outlet of the support tube. The measured fluid flows in from the front branch fluid, passes through the flow measuring tube and then flows out from the rear branch fluid, a full-through hollow tube is arranged between the flow measuring tube and the rear branch fluid, no movable or rotating part is arranged, and the measured fluid is not in direct contact with a detection part (a driving coil and a detection coil). So when calibration is not acceptable, or there are problems in use, the split flow and flow measurement tube are generally not problematic, and problems generally arise: the driving coil and the detection coil are damaged or are not properly arranged, the connecting line is damaged, the position of the damping plate is not proper, and the weight is not proper or is not properly arranged. When the problems occur, the Coriolis force mass flowmeter is dismounted from a pipeline and returned to an assembly workshop for shell opening treatment, maintenance and re-weighting, the workload is large, time and labor are wasted, the original shell cannot be used, the Coriolis force mass flowmeter after being re-mounted has the possibility of unqualified calibration when being re-calibrated, and the Coriolis force mass flowmeter needs to be re-shelled again. All flow measuring instruments except the coriolis force mass flowmeter are in contact with a measured fluid whether the detecting components are movable or fixed, and must be detached from a pipeline for maintenance.
Disclosure of Invention
In view of the problems caused by the totally enclosed design of the Coriolis force mass flowmeter, the utility model provides a detachable shell device of Coriolis force mass flow rate, which is safe, reliable, simple in structure and easy to produce.
In order to realize the purpose, the technical scheme of the utility model is as follows: a detachable shell device of a Coriolis force mass flowmeter comprises a detachable shell, a supporting tube, a connecting bolt and a sealing strip, wherein the outer surface of the lower portion of the supporting tube is connected with the inner surface of the upper portion of the detachable shell in a matched mode through respective connecting sealing surfaces, and the sealing strip is arranged at the sealing connection position to be fixed through the connecting bolt after being connected in a sealing mode.
Furthermore, the connection sealing surface of the supporting tube and the connection sealing surface of the detachable shell are inclined surfaces.
Further, the inclination of the inclined plane is 5 degrees.
Further, the height of the inclined plane is 15-50 mm.
Furthermore, a sealing groove is formed in the supporting tube connecting sealing surface and used for installing a sealing strip.
Furthermore, a row of connecting screw holes is formed above the sealing groove.
The utility model has the beneficial effects that: under normal operating mode condition, under the leakproofness and the waterproof nature circumstances of cavity in guaranteeing Coriolis force mass flowmeter, adopted the upper and lower inclined plane to add the detachable shell device that the sealing strip carries out sealedly, can be easy, repeated will dismantle the shell and install on the stay tube or dismantle from the stay tube to expose flow measurement buret, damping plate, balancing weight, drive coil, detection coil, line etc. easily detect, maintain, change. The problem of online detection and replacement during calibration of the Coriolis force mass flowmeter is solved, and online detection and maintenance performance under the working condition of the Coriolis force mass flowmeter are solved. Meanwhile, the sealing strips are used, so that the connection between the detachable shell and the supporting tube is changed into flexible connection (originally, the connection is welded and rigid), partial external transmission (shell vibration and supporting tube vibration which are mutually transmitted between the shell and the supporting tube) is eliminated and absorbed, and the reliability of the accuracy of the Coriolis force mass flowmeter is improved.
The purpose of the utility model is achieved.
