- Ordering Process
ZQDF (Y) series steam (liquid) solenoid valve is an actuator used in industrial process automation control system. It can open or close the valve automatically after receiving the electronically controlled signal, realizing the on-off or flow control of fluid medium in the pipeline, thereby automatically adjusting the temperature, flow rate, pressure and other parameters in the system or far away. Process control.
This series of solenoid valve products can be widely used in textile, printing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electrical appliances, surface treatment and other production and scientific research departments, as well as bathroom, canteen, air conditioning and other daily life facilities. ZQDF series is mainly used for the control of air, steam, gas and other gas media; ZQDF-Y series solenoid valves are mainly used for tap water, distilled water, frozen brine, electroplating waste liquids and other liquid media, but also for oil viscosity less than 4 degrees E.
Structural characteristics
Corrosion resistance: the main parts of the valve plug, valve body and so on are made of stainless steel and cast steel and have good anticorrosive property.
Heat resistance: The electromagnetic and sealing parts are all made of special high temperature resisting electrical materials and sealing materials, and effective heat insulation measures are adopted.
Wear resistance: material selection is reasonable, valve plug and valve body skillfully use the lubrication effect of fluid, reduce wear.
Condensation resistance: condensate in steam pipeline is an important factor affecting the operation of steam solenoid valve, the valve is not affected by condensate.
Structure and principle
The valve is a step-by-step direct pilot solenoid valve, which can be divided into normal closed solenoid valve and normal open solenoid valve according to the different open and close states when power is off. Normally closed solenoid valve, after the coil is electrified, the armature first drives the auxiliary valve plug to be lifted under the action of electromagnetic force. The fluid on the main valve cup flows away through the auxiliary valve, reducing the pressure on the main valve cup. When the pressure on the main valve cup decreases to a certain value, the armature drives the main valve cup and opens the main valve cup by using the pressure difference. Medium circulation. After the power is cut off, the electromagnetic force will disappear, and the armature will be reset because of its weight drop. At the same time, the main and auxiliary valves can be tightly closed depending on the medium pressure. Normally open solenoid valve, coil power on, moving iron core down, the secondary valve plug pressure, the secondary valve closed, the main valve cup pressure rise, when the pressure rises to a certain value, the main valve cup pressure difference is the same, because of electromagnetic force, moving iron core driving the main valve cup, pressure main valve seat, valve closed . When the coil is cut off, the electromagnetic suction is zero, the auxiliary valve plug and the movable iron core are lifted upward due to the spring action, the auxiliary valve opens, the fluid on the main valve cup flows away through the auxiliary valve, reducing the pressure on the main valve cup. 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, and the main valve opens. Medium circulation
