bookvalveIt is a solenoid valve with pilot two opening valve made up of two main parts: auxiliary valve and main valve. It depends on the opening and closing of the auxiliary valve to control the on-off of the main valve. According to the switch state when the power switch is different, it can be divided into normally closed solenoid valve and normally open solenoid valve. Normally closed solenoid valve, the power of normal position, the auxiliary valve port is closed, the main valve is cut off, when the signal into the pilot valve coil, the movable iron core is driven by electromagnetic force vice valve open suction mouth, rapid disappearance of the main valve valve cup pressure, medium pressure to the main valve valve cup holder, open the main the valve port, hard working medium circulation. But when the electric signal disappears, the movable iron core is reset, closing the auxiliary valve port, and the working medium self balancing hole enters into the valve cup. When the pressure tends to balance, the valve cup is moved down by the main valve spring, the valve cup self weight and the medium pressure, and the main valve port is tightly sealed, and the valve is closed. Normally open solenoid valve, in the power off position, by the role of the spring, vice valve opening, the main valve circulation. When the signal into the auxiliary valve coil, the movable iron core electromagnetic suction effect, the auxiliary valve port is closed, the working medium by balancing hole into the valve cup, when the pressure tends to balance, on the main valve spring, valve cup self weight and the medium pressure valve sealing cup down, close the main valve port, the valve is closed state. When the main valve is powered off, the electromagnetic force disappears, the vice valve opens, the main valve cup pressure disappears rapidly, the medium pressure will be the main valve cup support, open the main valve port, medium circulation, the valve is open.

Installation instructions

 

1, install the solenoid valve coil up and maintain the vertical position, solenoid valve on the arrow or marker should be consistent with the pipeline flow, shall not be installed in a splash of water or Water Leakage place.

 

2. The working medium of the solenoid valve should be clean without particle impurities, and the dirt and filter on the inner surface of the solenoid valve should be cleaned regularly.

 

3, in the solenoid valve failure, in order to isolate the solenoid valve in time, and ensure the normal operation of the system, it is best to install bypass devices (Figure 1).

 

4, in the pipeline system, the solenoid valve installed on the branch should be smaller than the diameter of the main pipeline valve (Figure two).

 

5, before the installation of solenoid valve, the pipeline must be cleaned. It is recommended to install filter in front of valve and install drain valve in steam pipe.

 

6, can not be concave valve installed in the pipeline, so as to avoid condensation of water vapor, impurities deposited on the valve and prevent action.

 

7, ordinary type can not be used in explosive dangerous occasions.

 

8, in the case of lack of rigidity of the pipeline, it is recommended to fix the pipeline before the valve, so as to avoid the vibration caused by the solenoid valve working.

 

9, before installation, should pay attention to see the product signs, carefully read the instructions, to determine whether the product meets the conditions of use.

 

10, solenoid valve before and after the installation of pressure gauges on the pipeline, in order to observe the pipeline pressure.

 

 

 

Service and maintenance

 

1, it is recommended that the use of units to send special personnel responsible for the use of maintenance.

 

2, solenoid valve installed after the media to enter the experimental action several times, to confirm the normal rear can be formally put into use.

 

3, should regularly clean large valve inside and outside the suction surface, pay attention to do not damage the sealing surface.

 

4, when the solenoid valve is not used for a long time, the valve should be closed before the manual valve, when re opened, the steam solenoid valve should be condensed water clean, and try several times, pending the switch is normal, can be put into use.

 

5. When the solenoid valve is unloaded from the pipeline, the internal parts should be cleaned and stored in compressed air.

 

6, the use of a long time, such as the piston and valve seat seal is not good, the piston sealing surface can be re polished, and now the valve seat grinding.

 

7, the work should pay attention to the pressure gauge before and after the valve, requiring the work pressure shall not exceed the rated pressure, the work pressure difference must be within the rated pressure range. When the working pressure exceeds the rated pressure or the working pressure difference exceeds the rated pressure difference, the solenoid valve should be stopped, the manual valve is closed before and after, so as to avoid the explosion and leakage of the solenoid valve.

 

Ordering instructions

 

1, when ordering, please specify type, nominal diameter, nominal pressure, working medium, working pressure difference, medium temperature, power supply voltage and power, medium viscosity.

 

2, the solenoid valve normal operation voltage is 220

+22

V, if exceed this range, please indicate voltage fluctuation when ordering. Other specifications supply voltage can be a special order.

-15

 

3, the valve opening time of more than 12 hours, please use open solenoid valve. When there are flammable and explosive products around the environment, please use explosion-proof solenoid valve
