The function of solenoid valve characteristics in the sale of products

Solenoid valve can be said to be everywhere in our life, widely used, frequently used, are the reasons why valve enterprises are emerging However, the production of solenoid valve is a technical activity, because after all, the safety of solenoid valve application is always * position Now, we know the main characteristics of the solenoid valve (1) external leakage is blocked, internal leakage is easy to control and safe to use Internal and external leakage is an element endangering safety Other automatic control valves usually extend the valve stem, and the electric, pneumatic and hydraulic actuators control the rotation or movement of the valve core All of these need to solve the leakage problem of long-term action valve stem dynamic seal; only the electromagnetic valve is completed by using the electromagnetic force to seal the iron core in the magnetic isolation sleeve, and there is no dynamic seal, so the leakage is easy to be blocked The torque control of electric valve is not easy, and it is easy to produce internal leakage, or even pull off the head of valve stem; the structure of solenoid valve is easy to control internal leakage until it is reduced to zero Therefore, the use of solenoid valve is particularly safe, especially suitable for corrosive, toxic or high and low temperature media (2) the system is simple, easy to connect computers, and the price is low The structure of the solenoid valve itself is simple and the price is low Compared with other kinds of actuators such as control valve, it is easy to install and maintain What's more, the automatic control system is much simpler and much cheaper Because the solenoid valve is controlled by switch signal, it is very convenient to connect with industrial control computer In today's era of computer popularization and sharp price decrease, the advantages of solenoid valve are more obvious (3) action express, small power, light shape The response time of the solenoid valve can be as short as several milliseconds, and even the pilot solenoid valve can be controlled within tens of milliseconds Because of self-contained loop, it is more sensitive than other automatic control valves The properly designed solenoid valve coil has low power consumption, which is an energy-saving product; it can also be used to trigger action and automatically maintain the valve position without any power consumption at ordinary times The external dimension of the solenoid valve is small, which not only saves space, but also is light and beautiful (4) the regulation accuracy is limited, and the applicable medium is limited Generally, there are only two states of the solenoid valve: on-off and on-off The valve core can only be in two limit positions and can't be adjusted continuously (there are many new ideas trying to break through, but they are still in the trial stage.) therefore, the adjustment accuracy is still limited The solenoid valve has a high requirement for the cleanliness of the medium The medium containing particles cannot be used If it is impurity, it must be filtered first In addition, viscous media can not be used, and the viscosity range of specific products is relatively narrow (5) various models and wide applications Although the solenoid valve has inherent shortcomings, the advantages are still very prominent, so it is designed into a variety of products, to meet different needs, a wide range of uses The progress of solenoid valve technology is also around how to overcome the inherent deficiencies, how to better play the inherent advantages and start By understanding the above five characteristics of solenoid valve, we can not only have a better understanding of solenoid valve, but also have a definite aim in production, and give customers more reasonable and useful suggestions in future sales Of course, to do solenoid valve industry, these can only be regarded as a fur, more still need to learn and progress in constant practice Shanghai Lidian solenoid valve Co., Ltd http://
