The development of the intelligent direction of the solenoid valve

The development of intelligent direction mainly refers to how electromagnetic valves cooperate better with intelligent instruments, so as to improve the control accuracy and reliability of the system. Generally speaking, bit conditioning is difficult to reach high precision, but in a lot of places the appropriate way can reach the required high precision, and save the cost greatly.

(1) double combined combination of electromagnetic wide. This is a combination of solenoid valves of different sizes. The fuel metering accuracy of a large number of refueling machines is as high as 0.02%. The large valve opens, which makes the fuel close to completion in a relatively short time. Then the big valve is closed, and the small valve is added to ensure the flow accuracy. This technology has been used abroad for many years, and is made by ascohoneywell, a world-famous solenoid valve company.

By the way, it is also pointed out that the large flow measurement of domestic oil depots is also introduced or copied from foreign countries with complex and unstable multi section shutoff valves. This product is not made by the famous professional companies of the world. In practice, the oil depot will be much better if it adopts a large volume double valve combined with domestic consumption. Double combination valves are often used to control temperature, pressure, liquid level and other parameters. The large valve ensures the base, and the small valve provides the compensation. In a system with relatively stable parameters, this bit control can achieve high accuracy.

For many systems with varying parameters, the rate of change is still limited, for example, the temperature control system is still affected by thermal inertia. Therefore, the proper combination of the combined valve can reduce the cost substantially when the control valve meets the control request.
