How to choose a valve factory

Solenoid valve manufacturers tell you, solenoid valve definition, classification and basic principles

Solenoid valve manufacturers are used to operate liquid automation technology of the basic components, belong to the electric actuator; Not limited to hydraulic press, pneumatic type. Solenoid valve manufacturer used to control the flow direction of hydraulic press. Plant equipment and fittings are generally controlled by hydraulic steel, so solenoid valves will be used.

Principle: intelligent toilet solenoid valve has a closed chamber, and open buried holes in different positions. Each hole leads to a different pipeline. The valve is located in the middle of the chamber and is flanked by two electromagnetic coils. Where the coil inductance inserted into the side of the oil circuit plate will move. Depending on the movement of the oil circuit plate, different oil discharge holes can be blocked or leaked. How much does the solenoid valve cost? The oil inlet is opened and closed, the gear oil enters the different tubing, and then the piston rod of the oil cylinder is lifted according to the working pressure of the oil, the fire plug pushes the hydraulic cylinder, and the piston rod pushes the mechanical equipment. In this way, the thermal motion of the molecules can be controlled according to the amount of current controlling the electromagnetic coil.

Classification and basic principle of intelligent toilet solenoid valve; The definition, classification and basic principle of intelligent toilet solenoid valve;

Basic principle of electromagnetic valve from around the world (i.e., straight acting, stage straight moving type and leading type) and piston valve on the structure and the differences of raw materials and the basic principle is divided into three types, they are divided into six branches project (the swash plate pulse dampers of thick plate structure, phase structure, head of structure, the structure of the inclined plate of the piston rod, phased inclined plate piston rod structure and the main structure of piston rod).

(1) Direct action of solenoid valve

Basic principle: when inserting, coil inductance makes the magnetic field force lift the fastener from the high pressure gate valve, and the globe valve opens; When the power is turned off, the magnetic force disappears, and the torsion spring presses the closing part on the high pressure gate valve, and the globe valve closes tightly.

Features: it can work normally under vacuum pump, negative pressure and zero pressure, but the pipe diameter is generally not more than 10mm.

② Direct action solenoid valve

Basic principle: Tight combination of rotary swash plate and pilot type is a basic principle. How much does the solenoid valve cost? When there is no pressure difference between the channel and the inlet and outlet, after the power supply is switched on, the magnetic force immediately lifts the fasteners of the pilot discharge valve and the pressure holding valve in turn, and the stop valve is opened. When the working pressure difference between the channel and the inlet and outlet is reached, after the power supply is connected, the magnetic field forces the plug-in exhaust valve, the working pressure of the lower chamber of the pressure retaining valve is increased, the working pressure of the chest and abdominal cavity is reduced, and then the pressure difference is used to pull the pressure retaining valve upward; When the power is off, the liquid control valve uses torsional spring force or material working pressure to push the closing parts down, so that the globe valve is closed tightly.

Features: can also be used in no differential pressure or vacuum pump, high pressure, but the output power is large, requiring horizontal installation.

High temperature steam solenoid valve

Basic principle: when inserting, the magnetic field force opens the main hole, and the working pressure of the upper cavity drops rapidly, resulting in low pressure difference around the fastener. The liquid working pressure makes the fastener move upward, and the cut-off valve opens. When the power is off, torsional spring force closes the main hole tightly. How much does the solenoid valve cost? The working pressure of the channel passes through the quick chamber of the side buried hole and creates a pressure difference between the upper and lower parts around the valve closed portion. The liquid working pressure causes the closing part to move down and tightly closes the two-position five-way solenoid valve.

Features: Liquid working pressure range is limited by height. Can be installed at will, but must meet the standard of liquid differential pressure.

In the application should also consider some of its characteristics, such as material properties, operating temperature, output power, switching power supply and other factors
