Product Description

ZCA Vacuum solenoid Valve Overview:
 
ZCA vacuum solenoid valve is suitable for vacuum equipment pipeline to do two-position on off switching actuator. It is widely used in food, metallurgy and other industries vacuum system pipeline.
 
First, ZCA vacuum solenoid valve principle
 
Solenoid valve has a closed chamber, open in different positions through the hole, each hole leads to a different tubing, the middle of the cavity is the valve, both sides are two electromagnets, which side of the magnet coil electrified valve body will be attracted to which side, by controlling the movement of the valve body to block or leak different oil discharge holes, and the oil inlet hole is often open, hydraulic oil will enter different drainage tubing, And then through the pressure of oil to promote the piston of the cylinder, the piston and drive the piston rod, the piston rod drives the mechanical device. In this way, by controlling the current of the electromagnet, the mechanical movement is controlled.
 

 

Two, the main characteristics of ZCA vacuum solenoid valve

(1) The external leakage is blocked, the internal leakage is easy to control, and the use is safe. Internal and external leakage is an element that endangers safety. Other automatic control valves usually extend the stem, and the rotation or movement of the spool is controlled by the electric, pneumatic and hydraulic actuator. All these must solve the problem of external leakage of long-term action valve stem dynamic seal; Only the solenoid valve is the electromagnetic force acting on the iron core sealed in the magnetic insulation tube of the electric regulating valve, there is no dynamic seal, so the external leakage is easy to block. Electric valve torque control is not easy, easy to produce internal leakage, and even pull off the stem head; The structure of the solenoid valve is easy to control the internal leakage until it is reduced to zero. Therefore, the solenoid valve is particularly safe to use, especially suitable for corrosive, toxic or high and low temper-ature media.
(2) The system is simple, it will be connected to the computer, the price is low and modest. The solenoid valve itself is simple in structure and low in price, and is easy to install and maintain compared with other kinds of actuators such as regulating valves. More significantly is the composition of the automatic control system is much simpler, the price is much lower. Because the solenoid valve is a switch signal control, it is very convenient to connect with the industrial control computer. In today's computer popularity, the price has fallen sharply in the er-a, the advantages of the solenoid valve is more obvious.
(3) Action express, small power, lightweight appearance. Solenoid valve response time can be as short as a few milliseconds, even pilot-ope-rated solenoid valve can be controlled in tens of milliseconds. Because of its own loop, it is more sensitive than other automatic control valves. Properly designed solenoid valve coil power consumption is very low, is energy-saving products; It can also be done only to trigger the action, automatically maintain the valve position, usually no power consumption. The solenoid valve is small in size, saving space, lightweight and beautiful.
(4) The adjustment accuracy is limited, and the applicable medium is limited. Solenoid valve usually only switch two states, the spool can only be in two limit positions, can not be continuously adjusted, (trying to break through a lot of new ideas, but are still in the trial stage) so the adjustment accuracy is still limited.
Solenoid valve has higher requirements for the cleanliness of the medium, including granular media can not be applied, such as impurities must be filtered first. In addition, the viscous medium can not be applied, and the medium viscosity range for specific products is relatively narrow.
(5) Variety of models, a wide range of uses. Although the solenoid valve has congenital shortcomings, the advantages are still very prominent, so it is designed into a variety of products to meet a variety of different needs, and is extremely widely used. The progress of solenoid valve technology is also centered on how to overcome congenital deficiencies and how to better play the inherent advantages.
