Shanghai and Shanghai Chen production ZQDF stainless steel / carbon steel steam explosion-proof solenoid valve

ZQDF solenoid valve solenoid valve product use ZQDF industrial process automation control systems actuators, it can automatically open or close the valve, to achieve off the pipeline fluid medium or flow regulation control after receiving the electrical control signal, and thus the system The temperature, flow, pressure and other parameters are automatically adjusted or remote control. ZQDF solenoid valve solenoid valve products can be widely used in textile, printing and dyeing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electronics, surface treatment and other production and scientific research departments as well as bathrooms, dining room, air conditioning and other facilities of daily life . ZQDF solenoid valve used to control air, steam, gas and other gaseous medium; ZQDF-Y series is mainly used for tap water, distilled water, chilled brine, electroplating waste water and other liquid media, as well as for oil viscosity of less than 4 ° E class. ZQDF solenoid valve Product Features: Corrosion: 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. Wear: the selection is reasonable, between valve plug and valve body clever use of fluid lubrication, reducing wear and tear. Resistance to cold: Cold North steam pipes are important factors affecting the operation of the steam solenoid valve, this valve is not subject to condensation effect. ZQDF solenoid valve structure and principles: ZQDF step-action solenoid valve direct pilot solenoid valve, which opened when power according to different off-state can be divided into normally closed solenoid valve and a normally open solenoid valve. After the normally closed solenoid valve, the coil is energized, the armature 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 leaving the use of pressure to open the main valve cup, medium flow. Coil power, the electromagnetic force disappears, the armature is reset by its own weight fall. At the same time rely on media pressure, the primary and secondary valve to be tightly closed. Normally open solenoid valve, the coil is energized due to the suction effect, moving core down, the vice-pressure valve plug, vice valve is closed, the main valve cup pressure rises when the pressure rose to a certain value, the main valve cup Like the upper and lower pressure, the electromagnetic force, the moving core loss of the main valve cup down, pressing the main valve seat, the valve is closed. When the coil power, 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 in the auxiliary valve on the flow away, reducing the role of the main valve cup The pressure, when the pressure on the main valve cup reduced to a certain value, the use of pressure to push up the main valve cup, the main valve is opened, the medium circulation.
