Solenoid valve as an automatic instrument actuator, the amount of a sharp increase in recent years. This paper analyzes the main characteristics of the solenoid valve, and focuses on the application's point of view, on the domestic development of mature technologies for a brief overview of, respectively, in the streamlining, intelligence, common and dedicated direction of study, and a little of the impact of electromagnetic valve technology for the social dimension of development are discussed.
(1) no leakage plugging, easy to control with the leakage, the use of security.
Internal and external leakage is a factor likely to affect safety. Other controlled valve stem out usually by electrical, pneumatic, hydraulic spool executive body to control the rotation or move. This needs to be tackled by stem seal leakage caused by problems outside; only electromagnetic solenoid valve is sealed in the following works for the magnetic core within the casing to complete, there is no dynamic seals, the leakage can easily block. Electric torque control valve is not easy, prone to leakage, and even pull off the head stem; the structure type solenoid valve with easy to control the leakage until zero. Therefore, the use of special safety solenoid valve, in particular, applicable to corrosive, toxic or high temperature media.
(2) the system is simple, will take computers, low cost him.
Solenoid valve itself simple structure, low prices, compared to other types of control valve actuators, such as easy installation and maintenance. More significant is the composition of the automatic control system is much simpler, much lower price. Solenoid valve is switched due to signal control, and industrial control computer is very convenient to connect. Universal in today's computers, an era of declining prices, the solenoid valve on the more obvious advantages.
(3) Action Express, power tiny, lightweight form factor.
Solenoid valve response time can be as short as a few milliseconds, even if the pilot-type solenoid valve can be controlled within a few dozen milliseconds. As the self-loop, other than more responsive control valve. Properly designed coil of solenoid valve power consumption is very low, an energy-saving products; action could also be just the trigger to automatically maintain valve position, usually is not power. Small size solenoid valve, saving space and beautiful light. valve ball valve gate valve check valve globe valve butterfly valve
