Description

[0002] Vortex flowmeter is a volume flowmeter that measures the volume flow rate of gas, steam or liquid, the volume flow rate under standard conditions or the mass flow rate based on the Karman vortex principle. It is mainly used for flow measurement of industrial pipeline medium fluids, such as gas, liquid, steam and other media. Due to the limitation of the site, the straight pipe section cannot be achieved, and a rectifier should be installed. It is a non-uniformly distributed multi-porous rectifier with low cost, easy installation, simple structure and small resistance loss.

[0003] After searching the Chinese patent number: CN218994420U, a vortex flowmeter with a built-in rectifier was found. In this design, the interior of the vortex flowmeter can quickly dissipate heat when conveying high-temperature media. The heat dissipation effect is very good. The heat dissipation of the vortex flowmeter is timely and effective, which avoids the vortex flowmeter from being overheated and ensures the normal use of the vortex flowmeter. However, this technical solution only cools the vortex flowmeter rod through natural cooling and air cooling, and both natural cooling and air cooling will be affected by the temperature of the working environment. When the temperature of the working environment is too high, the heat dissipation effect will be poor, affecting the service life of the vortex flowmeter. Now, a vortex flowmeter with a built-in rectifier is urgently needed to solve the above-mentioned problems. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a vortex flowmeter with a built-in rectifier to solve the problems raised in the above-mentioned background technology. The utility model has a reasonable structure. The design cools the vortex flowmeter rod by water cooling and air cooling, and will not be affected by the working environment temperature, so that the cooling and heat dissipation effect is better and the service life of the vortex flowmeter is increased.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme: a vortex flowmeter with a rectifier, comprising a fixed box, a micro blower, an air duct, a heat exchange water pipe, a return pipe, a liquid storage box, a connecting pipe and a micro water pump, a vortex flowmeter body is installed inside the fixed box, a porous rectifier is arranged inside the vortex flowmeter body, and a liquid storage box is installed on the left end surface of the fixed box;

[0006] The upper end surface of the vortex flowmeter body is connected to a meter rod, an instrument is fixed on the upper end surface of the meter rod, a protective sleeve is sleeved on the outer side of the meter rod annular surface, a vent hole is opened on the upper end surface of the protective sleeve, a support plate is installed on the right end surface of the fixed box body, a micro-blower is installed on the upper end surface of the support plate, an air duct is fixed between the micro-blower and the protective sleeve, a micro-water pump is installed on the right end surface of the liquid storage box body, a hot water exchange pipe is sleeved on the outer side of the meter rod annular surface, a connecting pipe is installed between the micro-water pump and the hot water exchange pipe, and a reflux pipe is connected between the left end surface of the hot water exchange pipe and the liquid storage box body.

[0007] Furthermore, the ventilation holes are provided in a plurality of groups, and the ventilation holes in the plurality of groups are equal in size and are arranged equidistantly around the ventilation holes.

[0008] Furthermore, the heat exchange water pipe is configured as a surrounding structure, the inner wall of the heat exchange water pipe can be fitted and connected to the outer wall of the meter rod, and the outer wall of the heat exchange water pipe can be fitted and connected to the inner wall of the protective sleeve.

[0009] Furthermore, a sealing gasket is provided between the connecting pipe and the hot water exchange pipe, a sealing gasket is provided between the connecting pipe and the micro water pump, a sealing gasket is provided between the return pipe and the hot water exchange pipe, and a sealing gasket is provided between the return pipe and the liquid storage tank.

[0011] Furthermore, the micro blower, air duct, hot water exchange pipe, return pipe, liquid storage tank, connecting pipe and micro water pump constitute a high-efficiency cooling component.

[0012] The beneficial effects of the utility model: the utility model is a vortex flowmeter with a built-in rectifier. Because the utility model adds a micro-blower, an air duct, a hot water exchange pipe, a reflux pipe, a liquid storage tank, a connecting pipe and a micro-water pump, the design cools the vortex flowmeter rod by water cooling and air cooling, and will not be affected by the working environment temperature, so that the cooling and heat dissipation effect is better, and the service life of the vortex flowmeter is increased. It solves the problem that the original vortex flowmeter with a built-in rectifier only cools the vortex flowmeter rod by natural cooling and air cooling, and both natural cooling and air cooling are affected by the temperature of the working environment. When the temperature of the working environment is too high, it will cause poor heat dissipation effect, affecting the service life of the vortex flowmeter. BRIEF DESCRIPTION OF THE DRAWINGS
