Solenoid valve technology characteristics and its development in our country

The solenoid valve technology characteristics and the development of our country network xiao wu time solenoid valve as a kind of automation instrument actuators. Consumption has risen dramatically in recent years, this paper analyzes the main characteristics of electromagnetic valve, and focusing on the application of domestic mature technology development trends are reviewed, in leaner, intelligent, generalization, specialty direction for investigation, and slightly to the social factors affecting the development of electromagnetic valve technology points discussed. The main characteristic of the electromagnetic valve ( ) Leakage plugging, and leak leakage is easy to control, the use of safe inside and outside of the elements, and other automatic control valve stem is usually stretched out by electric and pneumatic; Hydraulic actuator control valve core rotation or movement. Which will solve the long-term action of stem of dynamic seal leakage problem, only the electromagnetic valve is applied to seal in the magnetic separation electric magnetic core of casing completion, there is no dynamic seal, plugging and leakage easily so electric valve torque control is not easy. Prone to leakage. Even to break the stem head, within the structure is easy to control electromagnetic valve leakage. To zero. So solenoid valve using a special security, especially suitable for corrosive, toxic, or high and low temperature medium. ( ) System is simple, and the computer has simple structure, low price modest solenoid valve itself, the price is also low, 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 era of computers have fallen sharply, the advantage of the solenoid valve is more obvious. ( ) Action, express, power of tiny, light shape solenoid valve response time can be short as a few milliseconds. Even the guiding type solenoid valve can be controlled within tens of 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, also can do only trigger actions. Keep the valve position automatically. At ordinary times don't electricity. Electromagnetic valve size shape. Save a space. Light and beautiful again. ( ) Limited limited adjustment precision, applicable medium electromagnetic valve usually only two kinds of state switch. Only in two limit position valve core cannot continuous adjustment. So the adjustment accuracy is limited. Solenoid valves have higher request for medium cleanliness. Containing granular media cannot apply. In the case of a must be filter the impurities. In addition. A viscous medium can't apply. And. Specific products for the medium viscosity range is relatively narrow. ( ) Type diversity, the deficiency of solenoid valve is widely used, good still very prominent; So he designed a variety of products, meet the needs of different USES is very wide; Solenoid valve technology advances are also revolve around how to overcome the deficiency, how to better play to the inherent advantages.
