1. Read the product manual carefully before installation, check whether the product meets the requirements for use, remember the installation points, and prepare for the work.
2, pay attention to the cleanliness of the medium, if the medium is mixed with dust, impurities and other obstacles to the normal operation of the solenoid valve, the filter should be installed in the filter valve filter ≥ 60 mesh.
3. The solenoid valve should not be installed in the low recess of the pipeline. It should be installed in the discharge pipe of the container. Note that it should not be taken out from the bottom of the container, but should be installed at the bottom of the container.
4. If the medium will cause water hammer, then you should choose the solenoid valve with the function of waterproof hammer or take corresponding precautions.
5. The steam inlet side of the solenoid valve should be equipped with a steam trap, where the nozzle should be tilted.
6. Check whether the parameters of the nameplate are consistent with the parameters of the selected product. The power supply voltage should meet the rated voltage and voltage fluctuation range: AC +10%~-15%, DC +10%~-10%, usually the coil assembly should not be disassembled. .
7. Before the solenoid valve is connected, flush the pipe with a pressure of 0.3MPa, and remove the metal powder and the residue of the sealing material, rust and the like in the pipe.
8, the solenoid valve is generally oriented, can not be reversed, usually on the valve body with "→" to indicate the direction of media flow, installation should be in accordance with the direction of the "→" indication, but the company may sometimes be in the vacuum line or special circumstances There will be a proposal to disguise.
9. To confirm, there is a leak in the solenoid valve itself and its connection with the nozzle.
10. Check the connection of the coil lead wire, especially the case of three lead wires.
11. Electrical components connected to solenoid valves, such as relays, switches, and contactors. The contacts should not vibrate when the valve is opened, otherwise the work will be unreliable and affect the life of the solenoid valve.
12. The electrical circuit should be connected to the corresponding safety line as the protection of the electrical circuit.
13. The solenoid valve installation should have a certain reserved space for daily maintenance and regular maintenance.
14. When installing, fix the valve body with a wrench or pipe wrench, and then screw on the connecting tube. Do not apply force to the electromagnetic coil assembly to cause deformation, which makes the solenoid valve difficult to work normally.
15. In case of insufficient rigidity of the pipeline or water hammer, please fix the front and rear nozzles of the valve with brackets.
16. When using in a frozen place, the pipe must be protected with insulation or a heater should be placed on the pipe.
17. Installation posture: The electromagnetic coil components of the general solenoid valve should be vertically upright and installed vertically on the horizontal level of the pipeline. If it is subject to space restrictions or working conditions, it must be installed in the side like a building sewer or inverted. Please submit it at the time of order selection. Some products have special regulations, please follow the instructions.
18. When taking over, be careful not to use excessive amounts of sealing material. If the thread is connected, the thread of the nozzle should be kept within the effective length, and the edge of the end half pitch should be chamfered with a trowel. The sealing tape will be wound from the end of the 2 teeth, otherwise the excess sealing tape or adhesive will enter the electromagnetic The inner cavity of the valve, and an accident that interferes with normal operation occurs.
Knitted Blanket
Blanket is a commonly used bedding, which has the function of keeping warm. The knitted blankets we produce are thinner than quilts, but have better warmth retention. It has the characteristics of strong elasticity, strong warmth, thick texture, and is very durable, even if it is washed many times, it will not shrink and deform. According to specifications, it is divided into double blankets, single blankets and children blankets. You can customize the style and color of the blanket with us according to your needs, and we have quality assurance.
Yacheng Knitting Co., Ltd. can mass produce customized high-quality knitted garments, including sweaters, Custom Knit Sweaters, Knitted Pants, Knitted Skirt , Knitted Shoes, Knitted Scarves and Knitting Blanket. If you need to order knitted products, please contact us.
