How To Choose The Steam Solenoid Valve correctly?
Thermal power plant steam superheated steam
The base number of temperature and pressure changes is relatively large. The applicable temperature of the steam solenoid valve can be up to 400℃ or higher, and the working pressure is within 4.0Mpa. The hard-seal steam solenoid valve is usually used as follows:
Structural features: The use of metal hard seals improves the use temperature and service life of the product.
Reasonable selection of materials: the valve cup and guide sleeve cleverly use the lubrication effect of fluid to reduce wear.
Other uses-Hard-sealed steam solenoid valve has a wide range of applicable media, and can be used for water, light oil, heavy oil, non-corrosive gas, steam and other fluids. For example, in the drainage system of the exhaust pipe of the power station and the exhaust system of the evaporator, the two-position automatic adjustment and remote control of the medium in the pipeline are mainly carried out.
Working status: Normally closed type-power-on open, power-off closed normally open type-power-off open, power-off.
The steam solenoid valve is widely used in high temperature occasions. The automatic control system controls the switch of the steam solenoid valve according to the change of temperature and pressure, thereby achieving the control balance of the entire system and realizing automatic control. The steam solenoid valve is selected with high temperature heat sink, and further Protect the coil from overheating.
