Technical Field

[0001] The utility model belongs to the technical field of flow meters, and in particular relates to a porous plate of a balanced flow meter based on surface super-hydrophilicity. Background Art

[0002] With the rapid development of science and technology, the performance requirements for multi-hole balanced flowmeters have become higher. Therefore, it is necessary to improve the structure of multi-hole balanced flowmeters.

[0003] Most of the existing balanced flowmeter research focuses on the macroscopic structure of the porous plate, such as throttling holes, chamfers, cone angles, throttling hole distribution, etc., and has achieved relatively mature results. It is difficult to make a breakthrough in the performance of the balanced flowmeter by only optimizing the macroscopic structure. How to improve the porous plate from the microscopic structure to improve the efficiency and uniformity of the flowmeter has become a current problem. Therefore, how to provide a balanced flowmeter porous plate based on surface superhydrophilicity is an urgent problem to be solved by technicians in this field. Utility Model Content

[0004] The main purpose of the utility model is to provide a porous plate of a balanced flowmeter based on surface super-hydrophilicity to solve the above technical problems. The device is provided with a plurality of tiny square cylinders, which form a super-hydrophilic microstructure. The super-hydrophilic microstructure greatly increases the roughness of the surface of the porous plate, further increases its hydrophilicity on the original material, reduces the contact angle of the fluid on the surface of the porous plate, improves the passing efficiency of the fluid when passing through the porous plate, and also reduces the influence of vortex vortex on the surface of the porous plate. Because it covers the entire surface of the porous plate, it also improves the uniformity of the fluid when passing through, and improves the metering performance of the flowmeter.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The utility model is provided with a plurality of tiny square cylinders, and the plurality of tiny square cylinders form a super-hydrophilic microstructure. The super-hydrophilic microstructure greatly increases the roughness of the surface of the porous plate, further increases the hydrophilicity of the original material, reduces the contact angle of the fluid on the surface of the porous plate, improves the passing efficiency of the fluid when passing through the porous plate, reduces the influence of eddy current vortex on the surface of the porous plate, and because it covers the entire surface of the porous plate, it also improves the uniformity of the fluid when passing through, thereby improving the metering performance of the flow meter.
