What is the level of irrigation technology in my country? How does the solenoid valve work?

There are many factories of water-saving irrigation equipment manufacturers above designated size in my country. Production workshops, material yards, warehouses for semi-finished and finished products, and inspection and testing facilities can basically meet the requirements of industrial design regulations. A small amount of equipment is imported from abroad, and most enterprises have mold manufacturing capabilities. From the research and development of water-saving irrigation technology and equipment imported from abroad more than 30 years ago to today, Chinese enterprises have been able to manufacture almost all water-saving irrigation equipment in the world. There is still a certain gap between the manufacturing technology level of water-saving irrigation products for landscaping (including golf courses, sports fields, etc.) and similar products in the United States.

Solenoid valve (Solenoid valve) is an industrial equipment controlled by electromagnetic force. It is an automatic basic component used to control fluids. It belongs to actuators and is not limited to hydraulic and pneumatic. It is used to adjust the direction, flow, speed and other parameters of the medium in the industrial control system. Solenoid valves can cooperate with different circuits to achieve the expected control, and the control accuracy and flexibility can be guaranteed. There are many kinds of solenoid valves. Different solenoid valves play a role in different positions of the control system. The most commonly used ones are check valves, safety valves, directional control valves, and speed regulating valves.

There is a closed cavity in the solenoid valve, and there are through holes in different positions. Each hole is connected to a different oil pipe. There is a piston in the middle of the cavity, and two electromagnets on both sides. On the other hand, different oil discharge holes are opened or closed by controlling the movement of the valve body, while the oil inlet hole is normally open, the hydraulic oil will enter different oil discharge pipes, and then the piston of the cylinder is pushed by the pressure of the oil, and the piston again Drive the piston rod, and the piston rod drives the mechanical device. In this way, the mechanical movement is controlled by controlling the electric current on and off of the electromagnet.
