Steam solenoid valve into the boiler steam - saturated steam, thermal power plants out of steam - superheated steam two kinds. Steam solenoid valve is widely used in textile, printing, chemicals, plastics, rubber, pharmaceutical, food, building materials, mach inery, electrical equipment, surface treatment and research sectors and

Bathroom, dining room, air conditioning and other automation systems.
Structural features
Second pilot valve solenoid valve opening by the Vice-valve and the main valve assembly consisting of two
Heat: Electromagnetic parts, seals, some with special high temperature electrical materials and sealing materials, and the application of a variety of insulation measures
Wear: rational selection, valve cup and a guide suites clever use of fluid lubrication, reduce wear and increase life expectancy
Resistance to cold: steam pipe on the steam condensate is an important factor in the operation of the solenoid valve, the valve is not affected condensate
Works
1 Step steam solenoid valves is direct action pilot solenoid valve, according to the power at which the on and off states of different, can be divide d into the normally closed and normally open solenoid valve solenoid valve.
2 normally closed steam solenoid valve coil is energized, the armature of the electromagnetic driving force of the first vice valve Seti, the main valve on the cup fluid flow away through the auxiliary valve, reducing the role of the main valve pressure on the cup When the main valve to reduce the pressure on the cup to a certain value, the armature with

Move the main valve cup, and use pressure leaving open the main valve cup, medium flow. Coil power, the electromagnetic force disappears, the armature due to weight whereabouts reset. Also rely on media pressure, primary and secondary valve to close off.
3 steam normally open solenoid valve, the suction effect of the coil is energized, the plunger down, the sub-pressure valve plug, the pilot valve closed, the main valve cup pressure rise, when the pressure rose to a certain value, the main the vertical pressure valve cup, as a re sult of electromagnetic force, the movable core

Lost under the main valve cup, pressing the main valve seat, the valve closes. Coil power, the electromagnetic suction zero, deputy branch valve plug and the core role of the spring lift, vice valve is opened, the use of pressure to the main valve cup push up, the main valve is opened, medium flow.
Steam solenoid valve is installed
1, less rigid in the pipeline case, we recommend using the valve before the pipe bracket to prevent vibration caused when the solenoid valve work.
2, steam solenoid valve working media should be clean and free of particulate impurities, solenoid valve and dirt on the surface of the filter, to be periodically cleaned.
3, in the steam solenoid valve failure, in order to prompt isolation solenoid valves, and to ensure proper system operation, best to install a bypass device.
4, in the piping system, installed in the branch circuit electromagnetic valve size should be smaller than the main channel of the valve bore.
5, when installing the solenoid valve coil up and maintain the vertical position, the solenoid valve on the arrow or mark shall be consistent with the pipeline flow may not be installed in a place where splashing or leaks.
6, can not be steam solenoid valve installed in the pipeline low recess so as to avoid condensation of water vapor, impurities precipitate in the valve and prevent movement.
7, ordinary type can not be used in hazardous environments.
8, before installing steam solenoid valve, pipe must be cleaned. Recommended valve installed before the filter, steam trap piping installation.
9, before installation, pay attention to see the product label, carefully read the instruction manual to determine whether the products meet the conditions of use.
10, steam solenoid valve pressure gauge should be installed around the pipe in order to observe the pipeline pressure.  solenoid valve
