Photoelectric through-beam turbine flowmeter and its probe embedded injection molding process

Abstract

Provided is a photoelectric opposite injection type turbine flow meter. According to the photoelectric opposite injection type turbine flow meter, a shell is composed of a fluid guide tube and a data transmitting bin, and the data transmitting bin is connected on the fluid guide tube in a crossing mode and wraps the fluid guide tube from the two sides outside the fluid guide tube; a multifunctional pre-arranged diversion frame, an impeller assembly, a diversion plug assembly and a retainer ring are sequentially assembled from a fluid inlet to a fluid outlet of the fluid guide tube. According to the photoelectric opposite injection type turbine flow meter, a photoelectric sensing principle is adopted, by means of an opposite injection light path, the impurity contamination resistance is improved, electromagnetic interference resistance is achieved, the turbine flow meter is overall high in dielectric strength, and the application condition is widened; by means of a reliable optical material, contamination of magnetic materials is avoided; a probe of the photoelectric opposite injection type turbine flow meter is prepared into a prefabricated member after being bent, the prefabricated member is seamlessly integrated with the shell through a secondary encapsulation technology, it is guaranteed that the probe is precisely fit with a core-pulling mechanism, a production capacity and the yield are effectively increased, the service life of a mold is prolonged, the shrinkage phenomenon caused by non-uniform thickness during one-time injection molding is overcome, and by means of the increased thickness of the boss portion, the fluid penetration resistance capacity is enhanced.

Description

technical field [0001] The invention relates to a liquid flow meter for comprehensive analysis and measurement of liquid and a probe embedded injection molding process thereof, in particular to a probe embedded injection molding process of a photoelectric through-beam turbine liquid flow meter. Background technique [0002] With the development of modern technologies such as the Internet + and the Internet of Things, more quantitative requirements have been put forward for the traditional water treatment process, such as the temperature, water quality, flow rate and single treatment flow of a monitoring point flowing through the water treatment system. As well as the tracking of the processing capacity of the water treatment system, the degradation tracking and replacement reminder of key consumables, and the water leakage alarm. In order to achieve these quantitative monitoring purposes, it is generally necessary to use many discrete sensors and perform complex analysis and...

Problems solved by technology

In order to achieve these quantitative monitoring purposes, it is generally necessary to use many discrete sensors and perform complex analysis and calculations, which not only increases the workload of installation and development, but also increases the risk of water leakage. Some sensors may introduce magnetic materials that are harmful to health due to limited principles.
