The characteristics of the electromagnetic valve and the future development trends

The characteristics of the electromagnetic valve and the future development of dynamic electromagnetic valve solenoid valve solenoid valve time as an actuator of automation instrument, dosage increased in recent years. Analysis of the main characteristics of electromagnetic valve, and focuses on the application point of view, the development trends of domestic mature technology are reviewed, in leaner, intelligent, surveyed the generalization, specialty orientation, and slightly to the social factors affecting the development of electromagnetic valve technology make some discussion. ( ) System is simple, and the computer, the price is low. Electromagnetic valve itself has simple structure, low price, compared with the control valve and other kinds of actuators is easy to install and maintain. More significant is composed of automatic control system is much simpler, much lower prices. Because the electromagnetic valve is switch signal control, connection with industrial control computer is very convenient. In today's computers, prices plunged, the advantage of the solenoid valve is more obvious. ( ) Action express, tiny power, appearance and lighter. Electromagnetic valve response time can be short as a few milliseconds, even the guiding type solenoid valve can control in a few milliseconds. Because of its circuit, more sensitive than other automatic control valve of the reaction. Design of electromagnetic valve coil power consumption is low, energy-saving products; Can also be simply trigger action, keep the valve position automatically, no electricity at ordinary times. Electromagnetic valve size shape, save a space already, and light and beautiful. ( ) Leakage blocking, internal leakage is easy to control, the use of safe. The elements of internal and external leakage is unsafe. Other automatic control valve stem, is usually by electric, pneumatic, hydraulic actuators to control valve core rotation or movement. This is caused by the valve stem seal to solve the leakage problem; Only the electromagnetic valve is applied to seal in electric magnetic magnetic core of casing is completed, there is no dynamic seal, so leakage blocking off easily. Electric valve torque control is not easy, easy to produce internal leakage, even to break the stem head; Within the structure is easy to control electromagnetic valve leakage, until reduced to zero. So, electromagnetic valve using a special security, especially suitable for corrosive, toxic, or high and low temperature medium.
