Referring to fig. 1 to 4, a flowmeter for coal mine specifically includes a first cover plate 1, a sensor seat 2, a second cover plate 3, a first sensor 4, a second sensor 5, and a connection seat 6.
The present embodiment relates in particular to retrofitting a magnetic loop flowmeter comprising a measuring conduit 42 and a magnetic loop arranged thereon as a buoy 41 as the first sensor 4. By adopting the variable cross-section flow measurement principle, all internal parts are encapsulated in a brass metal pipe body (measuring conduit 42), so that the use and maintenance are convenient. When water passes through, the water flow can push the internal mechanism, so that the buoy 41 is driven to linearly move, and the red indicating ring on the buoy 41 can display the indicating flow value on the scale. The flow indicated by the float 41 is approximately linear with the pressure differential. The flow range is 50-550L/min, and the device is used for continuous monitoring, intermittent fault finding and test running of a water-based system, and can be widely applied to the fields of agricultural irrigation, construction, coal machines, petrochemical machinery and the like.
In some embodiments, the buoy 41 is provided with a threaded mounting hole, and the connection between the first sensor 4 and the second sensor 5 is achieved by means of the connection seat 6. The present embodiment uses a pull-wire sensor as the second sensor 5. When the buoy 41 moves, the stay wire sensor is driven to act.
In the embodiment, a first cover plate 1, a sensor seat 2 and a second cover plate 3 form a closed assembly, and the first sensor 4, the second sensor 5 and other elements are packaged in the closed assembly. The first cover plate 1 is provided with a window 11, and the window 11 is also provided with a flow scale display for manually reading flow values; the sensor seat 2 can provide a mounting carrier for the first sensor 4, the second sensor 5 and other elements; the second cover plate 3 is of a flat plate structure and has a closed protection function. In this embodiment, the sensor seat 2 includes a flat plate-shaped body 21, two mounting plates 22 disposed opposite to each other are disposed on one side of the body 21, two ends of the first sensor 4 are respectively mounted on the mounting plates 22, the first cover plate 1 has a cavity, and a mouth of the cavity covers the body 21 to seal the first sensor 4 inside the cavity of the first cover plate 1. The other side of the plate 21 is provided with a mounting chamber 23, and the second sensor 5 is disposed inside the mounting chamber 23 and is enclosed in the mounting chamber 23 by the second cover plate 3.
The first sensor 4 is a magnetic ring flowmeter, which is composed of a magnetic ring, a measuring conduit 42 and the like, when the fluid to be measured flows in from the inlet of the measuring conduit 42 and flows out from the outlet, the magnetic ring moves horizontally to the left, the magnetic ring is provided with marked scales, and the flow value of the fluid to be measured can be read through the window 11 of the first cover plate 1.
The second sensor 5 in this embodiment is a pull wire sensor, which is a sensor for measuring displacement, and has the characteristics of compact structure, small space size, high measurement accuracy, and the like, and can convert the sensed information into an electric signal or other needed information for output.
The connection seat 6 is an "L" shaped connection plate 22, the two arms of which are used to connect the first sensor 4 and the second sensor 5, respectively.
The first sensor 4 is installed above the sensor seat 2, the second sensor 5 is installed below the sensor seat 2, and the first sensor 4 is connected with the second sensor 5 into a whole through the connecting seat 6. A rectangular groove is formed in the middle of the sensor seat 2. When the buoy 41 of the first sensor 4 moves horizontally, the pull wire of the second sensor 5 is driven to extend. Through the assembly combination of the first cover plate 1 and the second cover plate 3, the first sensor 4 and the second sensor 5 can be packaged in the sealing assembly, and the functions of dust prevention, corrosion resistance and the like can be achieved.
When the fluid to be measured flows in from the inlet and flows out from the outlet, the fluid to be measured generates hydrodynamic force due to the throttling effect of the measuring conduit 42, the hydrodynamic force generates magnetic force to drive the magnetic ring (the buoy 41) to horizontally move, the magnetic ring drives the second sensor 5 to extend out, and the pull wire sensor can measure the displacement value of the flow of the fluid to be measured, so that the conversion of electric signals is realized, and the digital monitoring of the fluid to be measured is realized. When the fluid to be measured stops supplying, the magnetic ring automatically resets under the action of the internal spring of the measuring conduit 42. The energy in the whole measuring process is converted into 'hydrodynamic force-magnetic force-spring force', the numerical display of the measured fluid can be converted into an electric signal by a manual reading mode, and the electric signal is accessed into an electric control system and automatically read by a PLC controller.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the present utility model, which is intended to be covered by the claims of the present utility model.
