Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of vortex flow meters, and in particular to a high-precision vortex flow meter. Background Technology
[0002] Vortex flow meters, also known as vortex flow meters or Karman vortex flow meters, are researched and manufactured based on the Karman vortex street principle. They are mainly used for measuring the flow rate of fluids in industrial pipelines, such as gases, liquids, and steam. They are characterized by low pressure loss, a wide measuring range, and are almost unaffected by parameters such as fluid density, pressure, and viscosity when measuring volumetric flow rate under operating conditions. Vortex flow meters have diverse application environments.
[0003] In the prior art, patent document CN213657966U discloses a vortex flow meter, including a vortex flow meter body. A mounting base is provided on the upper surface of the middle part of the vortex flow meter body. A connecting rod communicating with the vortex flow meter body is provided on the mounting base. A heat sink with heat dissipation grooves is sleeved on the outside of the connecting rod. A fixing plate is provided on the top outer side of the heat sink. Two telescopic cylinders are symmetrically arranged on the fixing plate. The telescopic ends of the two telescopic cylinders are respectively connected to a radiator that cooperates with the heat sink. A cooling fan assembly is provided on the outer side of the radiator away from the heat sink.
[0004] During use, it was found that when the vortex flow meter encounters fluid containing oil, silicon particles, or other impurities, the accumulation of oil in the vortex flow meter may cause an oil film to adhere to the sensor surface. This can affect the formation and shedding of vortices, thereby affecting the normal operation of the vortex flow meter. Therefore, it is necessary to regularly remove the vortex flow meter for cleaning and remove impurities from the pipeline, which is not very convenient. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a high-precision vortex flow meter that improves the convenience of cleaning.
[0006] This utility model discloses a high-precision vortex flow meter, comprising a first pipe, a first valve, a second pipe, a second valve, and a vortex flow meter. The vortex flow meter is installed between the first pipe and the first valve. The first pipe has a first valve, and the second pipe has a second valve. The vortex flow meter includes a pipe body and a meter body, as well as a cleaning component and a drainage component. The pipe body has the cleaning component and the drainage component. In use, the first valve and the second valve are opened, and liquid is transported through the first pipe, the second pipe, and the pipe body. The vortex flow meter detects the flow rate. When it is necessary to clean the inside of the pipe body for oil stains, the first valve and the second valve are closed, and the cleaning fluid enters the pipe body through the cleaning component for oil stain cleaning. The cleaned oil stains and cleaning fluid are discharged through the drainage component. This allows for internal cleaning of the vortex flow meter without disassembly, improving convenience.
[0007] Preferably, the cleaning assembly includes a spray pipe frame, nozzles, a fixing plate, bolts, threaded grooves, an infusion pipe, and an infusion valve. Multiple sets of nozzles are installed inside the spray pipe frame, extending into the inner side of the pipe body. A fixing plate is mounted on the spray pipe frame, fitting the pipe body. Threaded grooves are provided at the bottom of the pipe body, and bolts pass through the fixing plate and are threaded into the grooves. An infusion pipe with an infusion valve is installed at the input end of the spray pipe frame. When oil stains need to be cleaned inside the pipe body, valves one and two are closed, and the infusion valve is opened. The cleaning fluid is injected into the infusion pipe through an external delivery device and enters the interior of the spray pipe frame. The cleaning fluid inside the spray pipe frame is sprayed into the pipe body through the multiple nozzles, thereby achieving cleaning of the pipe body and improving convenience.
[0008] Preferably, the drainage assembly includes a drainage pipe and a drainage valve. The drainage pipe is installed on the pipe body, and the drainage valve is installed on the drainage pipe. When it is necessary to clean the inside of the pipe body, the drainage valve is opened, so that the oil and cleaning fluid in the pipe body can be discharged through the drainage pipe, thereby improving convenience.
[0009] Preferably, it also includes sealing gaskets. A set of sealing gaskets is provided between the vortex flow meter and the first pipe, and another set of sealing gaskets is provided between the vortex flow meter and the second pipe. The two sets of sealing gaskets improve the sealing performance of the connection between the first pipe, the second pipe and the vortex flow meter, and prevent leakage.
[0010] Preferably, it also includes a thermometer, which is installed on the first pipe; the thermometer detects the temperature of the liquid inside the first pipe, improving convenience.
[0011] Preferably, the outer wall of the tube of the vortex flow meter is provided with an anti-rust coating.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, valves No. 1 and No. 2 are opened, and the liquid is transported through pipes No. 1 and No. 2 and the pipe body. The vortex flow meter detects the flow rate of the liquid. When it is necessary to clean the oil stains inside the pipe body, valves No. 1 and No. 2 are closed, and the cleaning fluid enters the pipe body through the cleaning component to clean the oil stains. The cleaned oil stains and cleaning fluid are discharged through the drainage component. This achieves internal cleaning of the vortex flow meter without disassembling it, improving convenience.
