Threaded steam solenoid valve

 ZQDF steam solenoid valve is threaded industrial process automation and control systems used in actuators, which can automatically open or close the valve, to achieve off the pipeline fluid medium or flow regulation control after receiving electrical control signal, and thus the system temperature, flow, pressure and other parameters are automatically adjusted or remote control. ZQDF threaded steam solenoid valve can be widely used in textile, printing and dyeing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electrical equipment, surface treatment and other production and scientific research departments and bathroom, dining room, air conditioning and other facilities in people's daily lives. ZQDF threaded steam solenoid valve used to control air, steam, gas and other gaseous medium; ZQDF threaded steam solenoid valve is mainly used for tap water, distilled water, chilled brine, electroplating waste water and other liquid media, but also for the viscosity of less than 4 ° E oils. Three, ZQDF steam solenoid valve threaded decay Features: The main components of the valve plug, body such as the use of stainless steel and cast steel, good corrosion resistance. Heat: electromagnetic, all using special high temperature sealing portion electrical materials and sealing materials, and the use of effective insulation measures. Wearable: selection and reasonable, between the valve plug and valve clever use of fluid lubrication, reducing wear and tear. Condensation resistance: Cold North steam pipes are important factors affecting the operation of the steam solenoid valve, this valve is not affected condensate. Four, ZQDF threaded steam solenoid valve structure and principle of the step-action valve for direct pilot solenoid valve, which open when power is based on the different off states can be divided into normally closed and normally open solenoid valve solenoid valve. After the normally closed solenoid valve, the coil is energized, the armature in the electromagnetic force to drive from the deputy valve Seti, fluid through the secondary valve flow away the main valve cup, reducing the role of the main valve cup of pressure, when the main valve reduce the pressure on the valve cup to a certain value, the armature drive the main valve cup, and use the pressure leaving open the main valve cup, medium flow. Coil power, the electromagnetic force disappears, the armature due to weight whereabouts reset. While relying on the media pressure, the main and auxiliary valves can be closed tightly. Normally open solenoid valve, the coil is energized due to the suction action, the movable core down, the auxiliary valve spool depressed, the auxiliary valve is closed, the main valve cup pressure rise, when the pressure rose to a certain value, the main valve cup The upper and lower pressure, as due to the electromagnetic force, the moving core loss of the main valve cup, the compression of the main valve seat, the valve is closed. When the coil is de-energized, the electromagnetic suction zero, vice valve plug and support the core due to the action of the spring Lift, vice valve is opened, the main valve cup of fluid through the secondary valve on the flow away, reducing the role of the main valve cup pressure, while reducing the pressure on the main valve cup to a certain value, the use of pressure to the main valve cup is pushed up, the main valve is opened, medium flow
