China's latest developments in technology and the characteristics of electromagnetic valve

Automatic Instrument as a solenoid valve actuator, a sharp increase in consumption in recent years. This paper analyzes the main characteristics of the solenoid valve. perspective and focus on the domestic application of mature technology for a brief overview of developments, in concise, intelligent, Universal, made a special inspection of the direction and strategy of electromagnetic valve for social factors point to explore the development of technology. First, the main features of solenoid valve
(1) blocking leak stopped, and easy to control leakage, the use of security. Leakage is a security threat and external factors. Other usually controlled valve stem protruding from the electrical, pneumatic and hydraulic control of the implementation of rotation or movement of the spool. This should solve the long-term movements in the foreign stem seal leakage problems; Only electromagnetic solenoid valve is used for sealing products in the magnetic core casing completed, there is no seal. Therefore, plugging leakage never easy. Electric valve torque control is not easy, which can easily lead to leakage, or even pulled off the valve head; solenoid valve control within easy structure of the leak until zero. Therefore, the use of special safety solenoid valve, especially in corrosive, toxic or high temperature media.
(2) The system is simple, then computer-low prices. Solenoid valve itself is simple, low prices, compared to other types of valve actuators easy to install and maintain. It is the more significant component of the control system is much simpler, much lower price. Because of the switch signal solenoid valve control, and industrial computers is very convenient. In today's widespread use of computers, an era of declining prices, the more obvious advantages of the solenoid valve.
(3) Action Express, micro-power, lightweight configuration. Solenoid Valve response time may be as short as a few milliseconds, even in the pilot-control solenoid valve can also dozens of milliseconds. As self-loop control valve more responsive than the other. Solenoid coil properly designed low power consumption, an energy-efficient products; Can only do action triggered automatic valve position to maintain, usually no electricity. Solenoid valve configuration is small, saving both space and light appearance.
(4) regulation accuracy restricted, limited media application. Solenoid valve switches usually only two state spool limit only in two locations, not for regulation, (trying to break a lot of new ideas, but also are at the trial stage of the trial), so precision is also subject to certain restrictions. Solenoid valve to a higher cleanliness medium, medium containing granulated not apply, in the case of impurities must be suppressed. In addition, the media could not be applied thick, but, given the relatively narrow scope of products applicable to the medium viscosity.
(5) various types, a wide range of uses. Solenoid Valve has inherent advantages still very conspicuous, so we designed a wide range of products, satisfy the various needs of a wide range of uses. Solenoid Valve technological advances are also centered on how to overcome the deficiencies, and how to bring into better play the inherent advantages start. Second, the development of solenoid valve 2.1 brief concise direction to the development of precision to use simple, but simple in the long-circulated. This is a permanent quest for scientists and engineers.
(1) for the implementation of simplified control loop past the large number of pneumatic and electrical control circuit. This increases the complexity of the system, in which the pilot valve solenoid valve type formed to capitalize on the media's own control loop. structure is simple. Previously, a number of technical parameters also restricted solenoid valve, solenoid valve path has been extended to domestic 30Omm; medium temperature as low as the 200 ° C, up to 450 ° C; pressure from vacuum to 25MPa.
