Solenoid valve as an instrument of automation, in recent years the increasing use of. Analyze the main features of the solenoid valve, and focus on the application point of view, the development of the domestic mature technology to make a brief overview, respectively, in the streamlined, intelligent, generalized, dedicated directions were investigated and slightly affect the solenoid valve technology The development of social factors for some discussion. (1) The system is simple, then the computer, the price is low Qian. Solenoid valve itself is simple, the price is low, compared to other types of actuators such as regulating valve easy to install and maintain. Even more remarkable is the composition of the control system is much simpler, the price is much lower. As the solenoid valve is the switch signal control, and industrial computer connection is very convenient. In today's popularization of computers, the price plummeted era, the advantages of the solenoid valve even more pronounced. (2) action express, power is small, lightweight appearance. Solenoid valve response time can be as short as a few milliseconds, even the pilot solenoid valve can be controlled within a few tens of milliseconds. Since the self loop, more responsive than other self-controlled valves. Well-designed solenoid valve coil power consumption is very low, is an energy-saving products; can also be done only trigger action, automatically maintain the valve position, usually do not consume electricity. Solenoid valve small size, saving space, but also lightweight and beautiful. (3) Blockage of external leakage, internal leakage easily controlled, safe to use. Internal and external leaks are elements that endanger safety. Other self-control valve stem usually stick out by the electric, pneumatic, hydraulic actuators to control the spool rotation or movement. This is to solve the valve stem seal caused by the external leakage problems; only the solenoid valve is the role of electromagnetic force sealed in the magnetic barrier tube within the iron core to complete, there is no dynamic seal, so easy to block leakage. Electric valve torque control is not easy, prone to internal leakage, and even pulled off the stem head; structure of the solenoid valve easy to control the internal leakage until it drops to zero. Therefore, the use of special safety solenoid valve, especially for corrosive, toxic or high temperature medium.
