● installation instructions 1
Before installation, carefully read the operation manual of the product, check whether the product fully meets the use requirements, get familiar with the installation points and make preparations
2
Check the parameters marked on the nameplate Whether it is the parameter of the selected product
Whether it is consistent with the operating instructions
3
Before taking over the pipe, fully flush the pipe with a pressure of 0
3MPa to completely remove the residual metal powder sealing materials and rust in the pipe
4
Pay attention to the cleanliness of the medium
If the medium is mixed with dust and dirt and impurities hinder the normal operation of the solenoid valve, a filter valve should be installed in the pipe
5
The solenoid valve should not be installed When the pipeline is low and installed in the pipeline of the container, pay attention not to lead out from the bottom of the container, but to install it slightly above the bottom of the container
6
If the medium will have water hammer, multi-functional solenoid valve should be selected or corresponding preventive measures should be taken
7
A drain valve should be installed at the inlet side of the solenoid valve for steam, where the connecting pipe should be inclined, and the drain valve should be installed at the low position
8
The magnetic valve is generally directional It is not allowed to install reversely
The "arrow" is usually used on the valve body to point out the medium flow direction
During installation, follow the "arrow" Install in the direction indicated
9
The solenoid coil components of general solenoid valves shall be upright and vertical to the pipe
Some products have special provisions, please install according to the instructions
10
When connecting pipe, pay attention to that the sealing material shall not be used too much
If threaded connection, the connecting pipe thread shall be kept within the effective length, chamfered with a file at the half pitch of the end, and wound tightly from 2 teeth from the end Sealing tape, otherwise excessive sealing tape or adhesive will enter the solenoid valve, resulting in accidents that hinder the normal operation
11
There should be a certain reserved space at the installation of the solenoid valve for its daily maintenance and regular maintenance
12
Fix the valve body with a wrench or pipe wrench during installation, and then screw on the connecting pipe
Do not apply force on the coil assembly to cause deformation, making the solenoid valve difficult to operate In order to work normally
13
In case of insufficient rigidity of the pipeline or water hammer, please firmly fix the front and rear connecting pipes of the valve with supports
14
When used in frozen places, protect the pipeline with thermal insulation materials or set a heater on the pipeline
15
Confirm whether there is leakage at the solenoid valve itself and its connection with the connecting pipe
16
Check the connection of coil outgoing line Check, especially in the case of three outgoing lines
17
Electrical components connected to the solenoid valve, such as relays, switches and contactors
The contacts shall not vibrate when opening the valve, otherwise the operation will be unreliable and affect the service life of the solenoid valve
18
The electrical circuit shall be connected to the corresponding safety wire as the protection of the electrical circuit
19
In order to facilitate maintenance and repair operations, or do not interrupt the continuity In production, for general solenoid valves, it is recommended to adopt bypass isolation installation method
