ZQDF steamSolenoid valvesayThe next book
A, ZQDFSteam solenoid valveyieldUse of goods:
Steam liquid ZQDF series solenoid valve automation and control systems with actuators in the industrial process, it can automatically open or close in an electrical control signalvalveThe fluid medium in the pipeline, the on-off or regulating the flow of control to automatically adjust or remote control of the time with the temperature, flow and pressure parameters.
The solenoid valve can be widely used in textile, printing, chemical, plastics, rubber, pharmaceutical, food, building materials, machinery, electrical appliances, surface treatment and other production and research sectors and bathroom, dining room,Air conditionerOther facilities of daily life, ZQDF series is mainly used for the control of air, steam and gas; ZQDF series solenoid valve is mainly used for tap water, distilled water, saline water, electroplating waste liquid medium, but also for the oil viscosity is less than 4.
Two, ZQDF steam solenoid valve product features:
Corrosion: the main components of the valve plug and the valve body made of stainless steel and cast steel, good corrosion resistance.
Heat: electromagnetic, special high temperature sealing part of all electrical materials and sealing materials, and the use of effective insulation measures.
Wear: rational selection, the valve plug and valve between the clever use of fluid lubrication, reduce wear.
Resistance to condensation: cold water from the North steam pipe is an important factor affecting the action of steam solenoid valve, the valve is not subject to condensation effect.
Three, ZQDF steam solenoid valve structure principle:
Steam solenoid valve is a direct step pilot solenoid valve action, according to the power off and off condition is different, can be divided into normally closed and normally open solenoid valve solenoid valve. 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. Coil power, the electromagnetic force disappears, the armature weight whereabouts reset. At the same time depending on the medium pressure, the main valve to close off. 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.
1、The product from the user from the date of receipt, enjoy the following three service pack:
（1） Close to 15Days Baotui, Baohuan, warranty;
（2） Close to 30Days replacement and repair;
（3） Close to 12Months (3 months warranty repair coil);
（4） Except for export to abroad;
2、The user from the date of purchase, enjoy lifelong service.
3、Disclaimer: product failure caused by the following reasons, is not within the scope of free warranty service shop:
（1） The user is not in accordance with the "fault instructions", caused by the operation requires the use of;
（2） The user is not with the shop (or manufacturer) and self repair or alteration of communication failure caused by the product;
（3） Because the user use environment lead to product failure caused by abnormal aging;
（4） The fault caused by earthquakes, floods, fires and other natural disasters or other disasters, abnormal voltage;
4、In the following circumstances, the hotel reserves the right to provide warranty service;
（1） Manufacturers of the product brand, trademark, logo nameplate damaged or illegible when;
（2） The user does not pay the payment;
（3） The user of this shop (or manufacturers) of the customer service service units deliberately conceal products in the installation, operation and maintenance or other improper usage;
5、For refund, replacement and repair services, must first confirm the attribution of responsibility, can be returned or repair;
The solenoid valve is widely used in steam medium heating, cooling, drying, high temperature setting, dyeing and finishing two two line automatic control system.
1、The use of the product is in accordance with the "use" instructions and technical conditions for the product;
2、Before installation, piping should be washed clean, clean the tube welding slag, flax, and other raw materials with waste material, the valve should be installed before the filter blocking;
3、The solenoid valve for high into a low, one-way, arrow marking fluid direction and valve;
4、The solenoid valve is generally installed horizontally, the coil vertically;
5、The electromagnetic valve of continuous work, the best use of the bypass pipe, easy maintenance;
6、Long time stop solenoid valve, should wash all parts before use, remove the coagulum, according to the original installed, can be used;
When the coil is energized, the formation of magnetic suction plunger lift stem, open the valve, the upper pressure through the pilot valve port under the load, the formation of pressure difference, the piston will hold open the main valve port.

All stainless steel steam solenoid valve and copper steam valve difference:
A: because the physical properties of materials, stainless steel is inert, in medium temperature rise or fall, can its thermal control effectively, so as to ensure the spool and valve body is not stuck or the gap is too large.
Two;304Stainless steel acid alkali, can be used in corrosive medium.
Three: because of the hardness of stainless steel was higher than that of copper, more in the process of using friction, collision, strike, especially the piston (spool) and the piston (body) friction, because of the long-term use of copper, prone to wear phenomenon, leading to failure, affect the use.
