Imported steam solenoid valve
Overview of imported steam solenoid valve products
  The US YLOK imported steam solenoid valve is mainly suitable for boiler steam-saturated steam, and steam from thermal power plants-superheated steam. Widely used in textile, printing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electrical appliances, surface treatment and scientific research departments, as well as automatic control systems such as bathrooms, canteens, and air conditioning
1. Saturated steam The temperature and pressure are relatively stable, the temperature is lower than 250℃, and the working pressure is lower than 6.4Mpa
2. The superheated steam has a large temperature and pressure change base. The maximum temperature can reach above 400℃, and the working pressure is lower than 4.0Mpa
Working principle of imported steam solenoid valve
1. The steam solenoid valve is a step-by-step direct pilot solenoid valve, which can be divided into a normally closed solenoid valve and a normally open solenoid valve according to the different open and closed states when the power is cut off.
2. Normally closed steam solenoid valve. After the coil is energized, the armature first drives the valve plug of the auxiliary valve to lift under the electromagnetic force, and the fluid on the main valve cup flows away 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 open the main valve cup and the medium flows. After the coil is powered off, the electromagnetic force disappears and the armature is reset due to its own weight. At the same time, depending on the medium pressure, the main and auxiliary valves can be closed tightly.
3. Normally open steam solenoid valve. After the coil is energized, the moving iron core moves down due to the suction force. The valve plug of the auxiliary valve is pressed down, the auxiliary valve is closed, and the pressure in the main valve cup rises. When the pressure rises to a certain value, the main The upper and lower pressure difference of the valve cup is the same. Due to the electromagnetic force, the moving iron core loses under the main valve valve cup, and the main valve seat is compressed and the valve is closed. When the coil is de-energized, the electromagnetic suction force is zero, the auxiliary valve plug and the supporting iron core are lifted up due to the action of the spring, the auxiliary valve opens, the main valve cup is pushed up by the pressure difference, the main valve opens, and the medium flows.
