Stainless steel steam solenoid valve detailed description ZQDF stainless steel steam solenoid valve is an actuator for industrial process automation control system. It can automatically open or close the valve after receiving the electric control signal to realize the on-off or flow adjustment control of the fluid medium in the pipeline. In this way, parameters such as temperature, flow, and pressure in the system can be automatically adjusted or remotely controlled. This series of solenoid valve products can be widely used in textile, printing and dyeing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electrical appliances, surface treatment and other production and scientific research departments, as well as bathrooms, canteens, air conditioners and other people’s daily life facilities. ZQDF series is mainly used for the control of air, steam, gas and other gas media; ZQDF-Y series is mainly used for liquid media such as tap water, distilled water, frozen brine, electroplating waste liquid, etc., and also used for oil with viscosity less than 4°E. Corrosion resistance: The main components valve plug, valve body, etc. are made of stainless steel and cast steel, with good corrosion resistance. Heat resistance: The electromagnetic and sealing parts are all made of special high temperature resistant electrical materials and sealing materials, and effective heat insulation measures are adopted. Wear resistance: Reasonable material selection, clever use of fluid lubrication between the valve plug and valve body to reduce wear and tear. Condensation resistance: The cold north water in the steam pipeline is an important factor affecting the action of the steam solenoid valve, and this valve is not affected by the condensed water. This valve is a step-by-step direct pilot solenoid valve, which can be divided into a normally closed solenoid valve and a normally open solenoid valve according to the different open and closed states when the power is off. Normally closed solenoid valve, after the coil is energized, the armature first drives the auxiliary valve plug to lift up under the action of electromagnetic force, and the fluid on the main valve cup flows away through the auxiliary valve, reducing the pressure acting on the main valve cup. When the pressure on the valve cup is reduced to a certain value, the armature drives the main valve cup, and uses the pressure difference to open the main valve cup and the medium flows. After the coil is powered off, the electromagnetic force disappears, and the armature falls and resets due to its own weight. At the same time, depending on the medium pressure, the main and auxiliary valves can be tightly closed. Normally open solenoid valve, after the coil is energized, due to the suction effect, the moving iron core moves down, the auxiliary valve plug is pressed down, the auxiliary valve is closed, and the pressure in the main valve cup rises. When the pressure rises to a certain value, the main valve cup Due to the electromagnetic force, the moving iron core loses the main valve cup, presses the main valve seat, and the valve closes. When the coil is powered off, the electromagnetic suction force is zero, the valve plug of the auxiliary valve and the supporting iron core are lifted up due to the action of the spring, the auxiliary valve is opened, and the fluid on the valve cup of the main valve flows away through the auxiliary valve, reducing the effect on the valve cup of the main valve. When the pressure on the main valve cup is reduced to a certain value, the main valve cup is pushed up by the pressure difference, the main valve is opened, and the medium flows.
