Working principle of steam solenoid valve
The 1. steam solenoid valve is a direct pilot solenoid valve, which can be divided into constant and open type solenoid valves according to the different state of opening and closing the power when the power is broken.
2. often closed steam solenoid valve, when the coil is electrified, the armature is brought up by the auxiliary valve plug under the action of electromagnetic force. The fluid on the main valve cup flows through the auxiliary valve, reducing the pressure on the main valve cup. When the pressure on the main valve cup is reduced to a certain value, the armature drives the main valve cup and uses the pressure difference to make the main valve cup. Open, medium circulation. After the power is cut off, the electromagnetic force will disappear, and the armature will be reset because of its weight drop. At the same time, the main and auxiliary valves can be tightly closed depending on the medium pressure. High pressure solenoid valve
3. often open steam solenoid valve, the coil is driven by the suction effect, moving iron core move down, the valve plug is pressed down, the vice valve is closed, the pressure in the main valve cup rises, when the pressure rises to a certain value, the upper and lower pressure difference of the main valve cup is the same, because of the electromagnetic force, the moving iron core loses the main valve cup, compress the main valve seat, valve. Close。 When the coil is broken, the electromagnetic suction is zero. The auxiliary valve plug and the iron core are lifted up because of the spring effect. The auxiliary valve opens. The main valve cup is pushed up with the pressure difference. The main valve is opened and the medium is circulated. In addition to the above products, the company also supplies a water solenoid valve, stainless steel solenoid valve and other products. The company has the most practical technology, professional operation team, for you to create a user experience as the premise of the service, the best service is our endless pursuit. Because of the people, so it is trustworthy; because professional, so you deserve it! The above information is for reference only.
