US steam solenoid pneumatic valve structure principle and maintenance

steam solenoid pneumatic valve is divided into steam boiler Saturated steam, steam power plant Two kinds of superheated steam. Steam solenoid pneumatic valve widely used for textile, printing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electrical appliances, surface treatment and scientific research departments and bathroom, dining room, air conditioning automatic control system, etc.
Us electromagnetic air valve ( Also known as L solenoid pneumatic valve) Sealing surface using ptfe, the heat resistance of degrees, corrosion resistance, high pressure can reach kg. The excellent performance is widely used in pneumatic valve steam and water piping, etc. Pneumatic valve parameters:

pneumatic valve body material: brass, stainless steel
mode of action: piston guiding type
use medium: air, water, steam, oil
pressure range. - 。 Mpa
power supply voltage: ACV, DCV (listed Can be customized special voltage)
installation method: horizontal structural principles:

US steam solenoid pneumatic valve by pneumatic valve body, cover, the guide head, moving iron core, the static iron core and the piston.
pneumatic valve body made of brass material pneumatic valve body and cover with the method of screw thread connection, then the guide pin head firmly. The guide head adopts electronic iron and key perfect welded together, is fixed by the copper ring again. Movement by electromagnetic coil current, magnetic core, so as to drive the moving iron core to open and close the pneumatic valve. Moving iron core USES different from static iron core material, respectively is composed of stainless steel and electronic iron and W is different with the sealing face instead of sealing mode, which USES cone seal. Piston is embedded with the material composition for four fluorine on the top and bottom seals at the same time, is composed of the inferior vena, can effectively by pressure difference and fast switch.
maintenance:
should be regular cleaning, high temperature steam solenoid pneumatic valve and bit off the dirt inside and outside, be careful not to damage the sealing surface.
and high temperature steam solenoid pneumatic valve is installed to access into the medium experiment several times, confirmed rear can put into normal use.
, use for a long time, such as between piston and pneumatic valve seat seal, piston sealing surface can be smooth again, again with the pneumatic valve seat grinding.
solenoid pneumatic valve, high temperature steam for a long time need not when, should close the pneumatic valve pneumatic valve, manual restart, solenoid pneumatic valve of steam condensed water should be ruled out clean, and try several times, to switch to normal rear can put into use.
solenoid pneumatic valve, high temperature steam discharged from the need not when, internal and parts should be stored wiping clean with compressed air blowing off.
, it is recommended to use the unit hold people accountable for use and maintenance.
, at work, must pay attention to the pneumatic valve and pressure gauge, the required working pressure shall not exceed the rated pressure, working pressure difference must be within the rated pressure difference. When working pressure over the rated pressure or differential pressure over the rated pressure difference, steam to stop using pneumatic valve, pneumatic valve manually, before and after closing to avoid electromagnetic pneumatic valve explosion and leakage.
