Irrigation microvalve is a key component in the irrigation system, and its working principle is directly related to the irrigation effect and water saving effect. Typically, irrigation microvalves use pressure control or electromagnetic control mechanisms to regulate water flow. In the pressure control system, the microvalve automatically opens or closes by sensing changes in water pressure to maintain stable water pressure within the system. This mechanism is suitable for simpler irrigation systems, such as drip irrigation systems or sprinkler irrigation systems.
For example, a common pressure control microvalve is designed using the spring principle. When the water pressure in the system exceeds the set value, the spring will be compressed, thereby opening the valve and allowing water to pass; when the water pressure drops to a certain level When, the spring returns to its original shape, the valve closes, and the water flow stops. This design is simple, reliable and suitable for many small irrigation systems.
On the other hand, solenoid-controlled microvalve controls the opening and closing of the valve through an electromagnetic coil. When current passes through the coil, the magnetic field created causes the valve to open, allowing water to pass; when the current is disconnected, the magnetic field disappears and the valve closes. This mechanism is more suitable for irrigation systems that require remote control or precise control of water flow, such as large farmland irrigation systems or urban landscape irrigation systems.
Irrigation microvalves have various working principles. Choosing a suitable working principle depends on the scale of the irrigation system, environmental conditions and requirements for flow control accuracy.
2. What are the key technologies of irrigation microvalve?
The design and manufacturing of irrigation microvalve involves many key technologies, which directly affect the performance and reliability of the microvalve. Among them, material selection is a crucial part. Since microvalves have been exposed to moisture, high temperature or low temperature for a long time, their materials must have good corrosion resistance and high temperature resistance. Commonly used materials include stainless steel, plastic, rubber, etc. Each material has its specific advantages and scope of application.
For irrigation environments that need to resist strong corrosion, stainless steel microvalves are an ideal choice because stainless steel has excellent corrosion resistance and mechanical strength and can work for a long time in harsh environments without damage.
In addition to material selection, sealing performance is also one of the key technologies for irrigation microvalves. Microvalve seals must be able to maintain a good seal under high pressure and temperature to prevent water leakage and valve failure. Silicone seals and fluororubber seals are common choices. They have excellent high temperature resistance and corrosion resistance and are suitable for various irrigation environments.
The structural design and manufacturing process of microvalves are also one of the key technologies. Reasonable structural design can reduce the resistance of the valve, improve the smoothness of water flow, and at the same time reduce energy consumption and leakage risk. Advanced manufacturing technology can ensure the processing accuracy and surface finish of microvalves, and improve their durability and reliability.
The key technologies of irrigation microvalve involve many aspects such as material selection, sealing performance, structural design and manufacturing process. Only by continuously innovating and improving on the basis of these key technologies can we produce irrigation microvalve products with excellent performance, stability and reliability.
With the continuous development of agricultural technology, irrigation microvalve, as one of the core components of the irrigation system, has broad application prospects in modern agriculture. First of all, irrigation microvalve can realize flexible and precise water resource control and improve the intelligence of irrigation level. By cooperating with sensors and automatic control systems, microvalves can adjust water flow and irrigation frequency in real time based on soil moisture, climate conditions and other factors to achieve precise irrigation and maximize crop yields.
Some advanced irrigation systems use intelligent control technology based on wireless sensor networks to achieve remote monitoring and control of farmland irrigation. Farmers can monitor soil moisture, water pressure and other parameters anytime and anywhere through their mobile phones or computers, and achieve remote control by adjusting irrigation microvalves, thereby improving the flexibility and response speed of the irrigation system.
The application of irrigation microvalves also helps save water resources and protect the ecological environment. Traditional irrigation methods often have problems such as water waste and soil salinization. Irrigation microvalve can accurately regulate water flow according to crop water demand and soil conditions, reduce water waste, reduce irrigation costs, and reduce soil salinization. risks, which is conducive to the protection and improvement of farmland ecological environment.
Irrigation microvalve plays an increasingly important role in modern agriculture, and its application prospects are very broad. With the continuous advancement and innovation of science and technology, it is believed that irrigation microvalves will play an increasingly important role in improving agricultural production efficiency, saving water resources, and protecting the ecological environment, and will make greater contributions to the sustainable development of agriculture.
