The valve is a direct-closing normally-closed solenoid valve in a step-by-step operation. After the coil is energized, the armature first drives the small valve to open, and the large valve opens under the effect of the formed medium pressure difference and electromagnetic force. The coil is de-energized, the armature component is reset, and the size valve is Use the pressure surface of the medium to close tightly.Normally open solenoid valve, after the coil is energized, the armature moves down under the action of magnetic force, pushing the sub-valve valve plug down, until the sub-valve is pressed tightly, the auxiliary valve is closed, because the upper and lower pressure difference of the main valve cup tends to be equal, the main The valve cup is pressed tightly by magnetic force and self-weight, and the valve is closed. When the coil is de-energized, the magnetic force is zero, the armature and the auxiliary valve plug are lifted by the spring, the auxiliary valve is opened, the medium in the main valve cup flows away through the auxiliary valve, the pressure drops, and the main valve cup rises from the lower differential pressure The main valve opens and the valve opens.

Seven, ZBSF full stainless steel solenoid valve installation instructions:
1. When installing, the solenoid valve coil is upward and maintains the vertical position. The arrow or mark on the solenoid valve should be consistent with the flow direction of the pipeline, and should not be installed in places with splashing water or water leakage.
2. The working medium of the solenoid valve should be clean and free of particulate impurities. The dirt and filter on the surface of the solenoid valve internal parts should be cleaned regularly.
3. When the solenoid valve is faulty, in order to isolate the solenoid valve in time and ensure the normal operation of the system, it is better to install a bypass device (Figure 1). Note: The valve on the bypass must be closed normally. If the solenoid valve is mounted on the bracket, the diameter of the solenoid valve should be smaller than the diameter of the valve on the main pipe.Figure (2).
4. Before installing the solenoid valve, the pipe must be cleaned. It is recommended to install a filter in front of the valve and a steam pipe to install the trap.
5. Do not install the valve in the low recess of the pipeline to prevent the condensation of steam, impurities and the like from freezing in the valve.
6, ordinary type can not be used in explosive places.
7. In the case of insufficient rigidity of the pipeline, it is recommended to fix the front and rear pipes with brackets to prevent vibration when the solenoid valve is working.
8. Before installation, pay attention to see the product label, read the instruction manual carefully, and judge whether the product meets the conditions of use.
9. The pressure gauge should be installed on the pipeline before and after the solenoid valve to observe the pipeline pressure.
Eight, ZBSF all stainless steel solenoid valve use and maintenance:
1. It is recommended to use a designated person to take care of the use.
2. After the solenoid valve is installed, it must be tested by the medium for several times. After confirming the normal condition, it can be put into formal use.
3. The dirt inside and outside the large valve and the suction surface of the armature should be cleaned regularly. Be careful not to damage the sealing surface.
4. When the solenoid valve is not used for a long time, the manual valve before the valve should be closed. When re-enabling, the steam solenoid valve should remove the condensed water and make a trial operation several times. It can be put into use after the switch is normal.
5. When the solenoid valve is removed from the pipeline, the internal parts should be tested and compressed and stored with compressed air.
6. When the use time is long, if the seal between the piston and the valve seat is not good, the piston sealing surface can be re-polished and then grinded with the valve seat.
7. When working, pay attention to the pressure gauge before and after the valve, the working pressure should not exceed the rated pressure, and the working pressure difference must be within the rated pressure difference. When the working pressure exceeds the rated pressure or the working pressure difference exceeds the rated pressure difference, the solenoid valve should be stopped, and the front and rear manual valves should be closed to prevent the solenoid valve from exploding and leaking.
