Key words: intelligent universal solenoid valve multi-function self-holding valve First, the main features of the solenoid valve
(1) 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 actuator control spool rotation or movement. This must solve the long-term action of the valve stem seal leakage problem; only the electromagnetic valve is the role of electromagnetic force sealed in the magnetic separation within the sleeve to complete the core, 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.
(2) The system is simple, then the computer, low prices 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.
(3) action express delivery, 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.
(4) regulation accuracy is limited, the applicable medium is limited. Solenoid valve usually only switch two states, the spool can only be in two extreme positions, can not be adjusted continuously (trying to break a lot of new ideas, but are still in the trial stage of the trial) so the regulation accuracy is subject to certain restrictions.
Solenoid valve on the media have a higher cleanliness requirements, including granular media can not be applied, in the case of impurities must be filtered out. In addition, viscous media do not apply and the range of medium viscosities for a particular product is relatively narrow.
(5) Model variety, wide range of uses. Despite the inherent lack of solenoid valve, the advantages are still very prominent, so it is designed into a wide range of products to meet a variety of different needs, a very wide range of uses. Solenoid valve technology is also progress around how to overcome the inherent deficiencies, how to better play its inherent advantages and expand. Second, the electromagnetic valve technology development profile
2.1 streamline the direction of development
To be fine to Jane, only a simple ability to long-term spread.
Solenoid valve as an instrument of automation, in recent years a sharp increase in the amount. This paper analyzes the main features of the solenoid valve, and focusing on the application of the angle of the development of the domestic mature technology to make a brief overview, respectively, in the streamlined, intelligent, universal, dedicated direction made a survey, and slightly affect the solenoid valve technology Development of social factors for some discussion.
