Irrigation solenoid valve application, irrigation solenoid valve working principle

Irrigation solenoid valve application

In Landscaping plays an indispensable role in water-saving irrigation and reducing the labor intensity of garden workers. Solenoid valve is widely used in the field of water-saving irrigation. Water irrigation control equipment, irrigation solenoid valves are commonly used status control equipment in automatic sprinkler irrigation systems.

The selection of sprinkler irrigation equipment plays a key role in the operation quality of the sprinkler irrigation system. As a control device, the solenoid valve has the characteristics of stable operation, long service life, and no harsh requirements on the working environment. Understanding the working principle and performance characteristics of solenoid valves and mastering their usage will be beneficial to equipment selection. Solenoid valves with good performance can actively contribute to the cost control and system operation of the entire green space sprinkler irrigation system.

Working principle of irrigation solenoid valve

The irrigation solenoid valve has a normally open type There are two types: solenoid valves used in green space sprinkler irrigation systems. Most of the solenoid valves used in green space sprinkler irrigation systems are of the normally closed induction type, that is: the solenoid valve is in a closed state when it is not working. When the solenoid valve is working, a safety current passes through the electromagnetic package, and the electromagnetic core is activated by electromagnetic induction. Move, thus opening the inlet hole;the opening of the inlet hole means that the pressure balance between the upper and lower chambers of the diaphragm is destroyed, and the diaphragm opens the channel under the action of the upstream water pressure, and the valve opens.

Irrigation solenoid valve is mainly composed of a valve body, a valve cover, a diaphragm, a solenoid package and a pressure regulating device. There is a small channel called an inlet hole on the valve body, which is connected to the diaphragm. , lower chamber and the space at the bottom of the electromagnetic package.

solenoid valve The valve body is generally made of engineering plastics, reinforced nylon or brass, the diaphragm is usually made of rubber material with good toughness, and the spring is made of stainless steel. These materials have good chemical stability and mechanical properties.
