Problems solved by technology

[0003] After searching the literature of the prior art, it was found that Ye Sheng and Hu Jie published a paper entitled "Research on Engine Fuel Consumption Test System Based on Virtual Instrument Technology" in "Journal of Zhejiang University" (Agriculture and Life Science Edition, No. 5 in 2005). "The paper proposed an engine fuel consumption test system, which mainly realizes the measurement and control of fuel flow through the fuel filling solenoid valve and weight sensor. The system has high measurement accuracy and can display instantaneous fuel consumption and average fuel consumption in real time. However, the oil-filled solenoid valve used in this system does not have the flow sensing function itself, and must cooperate with an external weight sensor to realize flow sensing, and the oil-filled solenoid valve cannot realize real-time control of fuel flow. The solenoid valve has not realized the integration of fuel flow measurement and control functions

Description

technical field [0001] The invention relates to a control device in the technical field of automation, in particular to a flow rate measureable and controllable electromagnetic valve. Background technique [0002] With the rapid growth of the world's economy and population, the consumption of water resources in the world is also increasing at an alarming rate. How to realize the recycling of water resources and save water has long been a common concern of mankind, which is related to human survival and development. . From the perspective of production process automation, how to save water and control water also deserves special attention. In a word, to realize the control problem of people's water consumption, it must rely on the water flow control device to realize it. Not only that, since ordinary solenoid valves have been widely used in the conduction and closure control of fluid flow, the flow control of different types of fluids in industrial automation must be realiz...
