Stainless steel threaded high temperature steam solenoid valve solenoid valve normally closed normally open solenoid valve DN206.
A,ZQDF steam solenoid valve.Product overview:
ZQDF steam solenoid valve.Automation and control systems with actuators of the industrial process, it can automatically open or close the valve in an electronic control signal, realize the regulation and control of the fluid medium in the pipeline on-off or flow, and thus the temperature of the system, flow and pressure parameters for automatic regulating or remote control.
ZQDF steam solenoid valve.Can be widely used in textile, printing and dyeing, chemical, plastics, rubber, pharmaceutical, food, building materials, machinery, electrical appliances, surface treatment and other production and research departments, as well as bathrooms, canteens, air conditioning and other people's daily living facilities. ZQDF steam screw electromagnetic valve is mainly used to control air, steam and gas; steam solenoid valve is mainly used for ZQDF screw tap water, distilled water, saline water, electroplating waste liquid medium, but also for the viscosity of less than 4 DEG E.
Three, ZQDF steam solenoid valve thread product features
Corrosion resistance: the main components of valve plug, valve body, etc. made of stainless steel and cast steel, corrosion resistance is good.
Heat resistance: electromagnetic and sealing parts adopt special heat-resistant electrical materials and sealing materials, and adopt effective insulation measures.
Wear resistance: material selection is reasonable, between valve plug and valve body skillfully use fluid lubrication, reduce wear and tear.
Resistance to condensation: the cooling water of the steam pipe is an important factor affecting the operation of the steam solenoid valve, and the valve is not affected by condensate water.
Four, ZQDF steam solenoid valve structure and principle.
The valve is a step action direct pilot electromagnetic valve, which can be divided into normally closed solenoid valve and normally open solenoid valve according to the different opening and closing states when the power is off. Normally closed solenoid valve coil is energized, the armature of the electromagnetic force of the first drive side valve SETI, the main valve cup of the fluid flow out by the vice valve, reducing the pressure in the main valve valve cup, when the main valve to reduce pressure on the cup to a certain value, the armature driving the main valve valve cup, and use pressure to open the main valve cup, medium circulation. After the coil is switched off, the electromagnetic force disappears, and the armature is reset due to the weight drop. At the same time, depending on the pressure of the medium, the main and auxiliary valves are closed tightly. The normally open solenoid valve, the suction after the coil is energized, moving core down, the vice valve pressure, the Deputy valve closed, the main valve valve cup pressure rise, when the pressure rose to a certain value, the main valve valve cup upper and lower pressure, due to electromagnetic force, the moving core loss the main valve valve cup, pressing the main valve seat, the valve closed. When the coil power, the electromagnetic force is zero, the Deputy valve plug and a core role of the spring lift, vice valve is opened, the main valve cup of the fluid flow out by the vice valve, reducing the pressure in the main valve valve cup, when the main valve to reduce pressure on the cup to a certain value when the use of pressure to push the cup from the main valve, the main valve open, medium flow.
