The steam solenoid valves we come into contact with in our daily lives are often divided into two types:
1. Boiler steam - saturated steam
2. Steam from thermal power plants - superheated steam
1. Saturated steam: relatively stable temperature and pressure, temperature below 250 ℃, working pressure below 1.6Mpa
2. Overheated steam: with a large base of temperature and pressure changes, the highest temperature can reach over 400 ℃, and the working pressure is below 4.0Mpa
Classification of steam solenoid valves
For the first type of steam, we usually choose soft sealed steam solenoid valves.
Structural characteristics
This valve is a pilot operated secondary opening solenoid valve composed of two main components: the auxiliary valve and the main valve
advantage
Heat resistance: Special high-temperature resistant electrical and sealing materials are used for the electromagnetic and sealing parts, and various insulation measures are applied
Wear resistant: Reasonable material selection, valve cup and guide sleeve cleverly utilize the lubrication effect of fluid to reduce wear and improve service life
Condensation resistance: The condensation water in the steam pipeline is an important factor affecting the operation of the steam solenoid valve, while this valve is not affected by condensation water
Soft sealed solenoid valve
This series of solenoid valves can also be widely used in textile, printing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electrical, surface treatment steam solenoid valves, scientific research departments, as well as automatic control systems for bathrooms, canteens, air conditioning, etc.
Classification of steam solenoid valves
For the second type of steam, we usually choose hard sealed steam solenoid valves
Structural characteristics
Adopting metal hard sealing improves the product's operating temperature and service life
Reasonable material selection, cleverly utilizing the lubrication effect of fluid in the valve cup and guide sleeve to reduce wear
Hard sealed solenoid valve
This product has a wide range of universal media and can be used for fluids such as water, light oil, heavy oil, non corrosive gases, and steam.
In the drainage system of power station exhaust pipelines and the exhaust system of evaporators, the main function is to perform dual position automatic regulation and remote control of the medium in the pipelines.
working condition
Normally closed - powered on to open, powered off to close
Normally open - power off to open, power on to close
