Electromagnetic valve for controlling flow

Abstract

The invention discloses an electromagnetic valve for controlling flow. The electromagnetic valve for controlling flow can control the flow and flow speed of fluid through a flow control unit, so thata counting part is relatively independent of a base table part; reliable waterproofing guarantee is provided for an electronic device; the problem of magnetic interference is avoided; meanwhile, the base stable has higher startup flow and range ratio; only one detection probe is required to recognize the direction of water current, and the detection power consumption is lowered; cooperative sensing detection of a single chip microcomputer is not required, and a level pulse signal is output directly; and a terahertz time-domain spectroscopy technology is used for measuring the pipeline corrosion degree. The electromagnetic valve has the advantages of simple structure, convenience in operation, high detection accuracy for the corrosion degree, high system stability, safety, reliability, wideapplication range, easiness in operation, rapid detection, simple data processing process, high repeatability, high result accuracy and the like.

Description

technical field [0001] The invention relates to the technical field of electromagnetic valves, in particular to an electromagnetic valve for controlling flow. Background technique [0002] Although the existing water-saving irrigation system has a significant effect on reducing the crop irrigation system and increasing the crop yield, the rationality of irrigation cannot be further improved due to the large variability of manual operation. The drip irrigation automation control system controls various valves in the field through the collection and analysis of various factors such as soil, crops, and weather, and the operating system sends relevant information instructions to reduce the unreasonable factors of manual analysis and decision-making. Impact on agricultural irrigation. As the development trend of modern agriculture, under the premise that the current agricultural irrigation has implemented large-scale water-saving projects, further promoting the use of drip irrig...

Problems solved by technology

[0005] In addition, the existing solenoid valves often use sealing plugs to block the flow channel of the valve body. When the liquid controlled by the solenoid valve is strong acid or alkali, it will cause corrosion of the sealing plug. On the one hand, it will cause electromagnetic The sealing performance of the valve itself is reduced. On the other hand, when the sealing plug is severely corroded, it needs to be replaced. The solenoid valve is a precision part, and it takes time and effort to replace it. Moreover, the solenoid valve often appears blocked when it is actually used. , which in turn causes the problem that the solenoid valve cannot realize its own opening and closing function
