As a kind of actuator for automatic instruments, automotive solenoid valves have increased dramatically in recent years. The use of automotive solenoid valves has several advantages:
(1) The external leakage is blocked, the internal leakage is easy to control, and the use is safe.
Internal and external leakage is an essential element of safety. Other self-control valves typically extend the valve stem and control the rotation or movement of the spool by an electric, pneumatic, hydraulic actuator. This must solve the problem of external leakage of the long-acting valve stem dynamic seal; only the electromagnetic valve is applied by the electromagnetic force to the iron core sealed in the magnetic isolation sleeve, and there is no dynamic seal, so the external leakage is easy to block. The electric valve torque control is not easy, it is easy to produce internal leakage, and even the stem of the valve stem is broken; the structure of the electromagnetic valve is easy to control the internal leakage until it drops to zero. Therefore, solenoid valves are particularly safe to use, especially for corrosive, toxic or high temperature media.
(2) The action express, the power is small, and the shape is light.
Automotive solenoid valve response times can be as short as a few milliseconds, even pilot solenoid valves can be controlled in tens of milliseconds. Due to the self-contained loop, it is more sensitive than other self-controlled valves. The well-designed solenoid valve coil has low power consumption and is an energy-saving product. It can also be used to trigger the action and automatically maintain the valve position, and it does not consume electricity at all. The solenoid valve has a small size, which saves space and is light and beautiful.
(3) The system is simple, then the computer is connected, and the price is low.
The automobile solenoid valve itself has a simple structure and a low price, and is easy to install and maintain compared to other types of actuators such as a regulating valve. What's more remarkable is that the self-control system is much simpler and the price is much lower. Since the solenoid valve is controlled by the switching signal, it is very convenient to connect with the industrial computer. In today's era of computer popularization and price drop, the advantages of solenoid valves are even more obvious.
