Description

Technical Field

[0001] The utility model relates to the field of flow meters, in particular to a flow meter with a boosting mechanism. Background Art

[0002] The turbine flowmeter is a velocity flow meter with temperature and pressure compensation functions. It is a type of velocity flowmeter. Its working principle is: the power of the flowing fluid drives the turbine blades to rotate, and its rotation speed is approximately proportional to the volume flow rate. The fluid volume indication through the flowmeter is based on the number of revolutions of the turbine impeller. In the prior art, the Chinese utility model patent with announcement number: CN212567525U discloses a gas vortex flowmeter with filtering function. The utility model can stably filter impurities in the gas, ensure the accuracy of the gas, and avoid the accumulation of impurities in the gas inside the flowmeter body to affect the overall detection accuracy.

[0003] However, in actual use, the turbine flowmeter measures the flow of the medium by rotating the turbine, so it is necessary to ensure that the medium has a certain flow rate when flowing into the flowmeter. If there is no external pressurization device when the water enters, the medium may flow into the turbine flowmeter at a very low speed, affecting the measurement accuracy of the flowmeter. The impurities in the vortex flowmeter come from the fluid medium. Therefore, when filtering the impurities, the filtering structure cannot be set in the flowmeter, otherwise the dirt will still accumulate on the side of the filtering structure in the flowmeter, so it needs to be improved.

The No. 2 connecting head 404 is fixedly connected to the other side of the vortex flowmeter 1, and the No. 2 connecting sleeve 406 is fixedly connected to one end of the connecting pipe 405. The No. 2 connecting head 404 and the No. 2 connecting sleeve 406 are fixedly connected by threads. The side position of the vortex flowmeter 1 is provided with a booster pump 402, and the speed of the fluid is increased by the booster pump 402. Through the continuous operation of the booster pump 402, the fluid medium is stably input into the vortex flowmeter 1, so that the detection result of the vortex flowmeter 1 is more accurate.

[0024] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the connecting pipe 405 is fixedly connected to the side position of the boosting pump 402, the valve 407 is movably installed on the connecting pipe 405, the water tank 408 is fixedly connected to the connecting pipe 405, the screw 409 is movably installed in the water tank 408, the filter plate 412 is movably installed on the screw 409 and is located at the inner side of the water tank 408, the sealing ring 415 is fixedly connected to the edge position of the filter plate 412, the box cover 416 is fixedly connected to the upper position of the water tank 408, the boosting component 4 also includes a bearing 410 and a handle 411, the screw 409 is movably installed with the water tank 408 through the bearing 410, the handle 411 is fixedly connected to the lower end position of the screw 409 and is located at the lower position of the water tank 408, the boosting component 4 also includes a screw hole 413 and a filter hole 414, the filter hole 414 and the screw hole 413 are both opened on the filter plate 412, and the screw hole 414 is fixedly connected to the filter plate 412. 13 is located at the center of the filter plate 412, the screw 409 is movably installed with the screw hole 413 of the filter plate 412, the booster assembly 4 also includes a sealing gasket 417 and a water inlet pipe 418, the sealing gasket 417 is fixedly connected to the box cover 416, the box cover 416 and the water tank 408 are fixedly connected by threads, and the water inlet pipe 418 is fixedly connected to the box cover 416.

[0025] It should be noted that the utility model is a flow meter with a boosting mechanism. During the use of the vortex flowmeter 1, it is necessary to ensure that the flow rate is sufficient and remains stable, otherwise the rotating turbine of the vortex flowmeter 1 is affected, which may easily cause the detection result to be inaccurate. Therefore, a boosting pump 402 is provided on the side of the vortex flowmeter 1. The boosting pump 402 increases the fluid speed entering the vortex flowmeter 1, and the continuous operation of the boosting pump 402 allows the fluid to be stably transported to the vortex flowmeter 1, so that the detection result of the vortex flowmeter 1 is more accurate. A water tank 408 is provided at the side of the booster pump 402. External fluid enters the water tank 408 through the water inlet pipe 418 for waiting. The fluid volume is stored in the water tank 408. The water tank 408 is made of transparent material, such as glass, plastic, etc., so that the fluid medium in the water tank 408 is easy to observe. For some high-temperature fluid media, the valve 407 can be closed to allow the fluid medium to stand in the water tank 408 for cooling. Then, the valve 407 can be opened to allow the fluid medium to enter the vortex flowmeter 1 through the connecting pipe 405 and the booster pump 402. The medium passes through the filter plate 412 in the water tank 408, so that the fluid medium is filtered of impurities, and the impurities stay on the filter plate 412. The inner wall of the water tank 408 is located above the filter plate 412 and is also easily contaminated with impurities. A sealing ring 415 is filled between the filter plate 412 and the water tank 408. When it is necessary to clean the dirt, the valve 407 is closed, the box cover 416 is rotated to open, and the handle 411 is turned to make the screw 409 rotate synchronously in the screw hole 413 of the filter plate 412, and the filter plate 412 moves upward. The sealing ring 415 is filled in The outer side between the water tank 408 and the filter plate 412 may have anti-slip grooves to squeeze and fix the filter plate 412, so that the filter plate 412 is not easy to rotate with the screw 409, so that the filter plate 412 can be easily moved upward or downward with the operation of the screw 409, so as to move the filter plate 412 out of the water tank 408, and the sealing ring 415 scrapes the inner wall of the water tank 408 to scrape off the dirt on the inner wall, and then the filter plate 412 can be cleaned to remove the dirt, so that the filter plate 412 is easy to install and disassemble, and the dirt cleaning is more convenient.
