What are the main features of the solenoid valve? Today, the small series of Wanshou Hardware Machine Network will introduce you to everyone:

(1) The external leakage is blocked, the internal leakage is easy to control, and the use is safe. Internal and external leakage is an essential element of safety. Other self-control valves typically extend the valve stem and control the rotation or movement of the spool by an electric, pneumatic, hydraulic actuator. This must solve the problem of external leakage of the long-acting valve stem dynamic seal; only the electromagnetic valve is applied by the electromagnetic force to the iron core sealed in the magnetic isolation sleeve, and there is no dynamic seal, so the external leakage is easy to block. The electric valve torque control is not easy, it is easy to produce internal leakage, and even the stem of the valve stem is broken; the structure of the electromagnetic valve is easy to control the internal leakage until it drops to zero. Therefore, solenoid valves are particularly safe to use, especially for corrosive, toxic or high temperature media.

(2) The system is simple, then the computer is connected, and the price is low. The solenoid valve itself is simple in structure and low in price, and is easy to install and maintain compared to other types of actuators such as regulating valves. What's more remarkable is that the self-control system is much simpler and the price is much lower. Since the solenoid valve is controlled by the switching signal, it is very convenient to connect with the industrial computer. In today's era of computer popularization and price drop, the advantages of solenoid valves are even more obvious.

(3) The action express, the power is small, and the shape is light. The solenoid valve response time can be as short as a few milliseconds, even a pilot solenoid valve can be controlled in tens of milliseconds. Due to the self-contained loop, it is more sensitive than other self-controlled valves. The well-designed solenoid valve coil has low power consumption and is an energy-saving product. It can also be used to trigger the action and automatically maintain the valve position, and it does not consume electricity at all. The solenoid valve has a small size, which saves space and is light and beautiful.

(4) The adjustment accuracy is limited, and the applicable medium is limited. Solenoid valves usually only have two states of switching. The valve core can only be in two extreme positions and cannot be continuously adjusted. (There are many new ideas for breaking through, but they are still in the trial and trial stage), so the adjustment accuracy is also limited. Solenoid valves have high requirements on the cleanliness of the medium. Granular media cannot be used. If it is an impurity, it must be filtered first. In addition, viscous media is not suitable, and the viscosity range of the medium for a particular product is relatively narrow.

(5) Various models and wide range of uses. Although the solenoid valve is inherently insufficient, the advantages are still outstanding, so it is designed into a wide variety of products to meet a variety of needs, and is extremely versatile. The advances in solenoid valve technology are also centered around how to overcome the inherent deficiencies and how to better develop their inherent advantages.
