How to properly maintain the pneumatic diaphragm valve?

1. Pneumatic diaphragm valve should be placed in a boring and ventilated room, do not stack place.
2. It is necessary to seal both ends of the path of the stock pneumatic sanitary diaphragm valve in order to prevent foreign material from entering the inner cavity and damaging the sealing parts.
and avoid touching oils or other flammable items.
3. The metalworking appearance of the pneumatic sanitary diaphragm valve should be removed and coated with rust oil.
oil cups are often filled with grease.
4. Do not brush grease-like items on the surface of the lining layer or rubber diaphragm to avoid the appearance of rubber swelling and affect the service life of the valve.
5. During storage or deactivation, the hand wheel should be rotated counterclockwise to keep the valve in a slightly enlightened condition and to avoid losing elasticity due to prolonged pressure on the diaphragm.
. During transport or during installation, the sling must not be tied to the hand wheel or stem.
and prohibits contact with other metal or hard objects to avoid damaging parts and linings.
7. Before the installation, carefully check whether the operating conditions of the lines and the media are in line with the scope of application of the valve, to avoid improper selection and the formation of unnecessary loss, or even accidents.
. In addition to not suitable for use on vacuum lines, pneumatic sanitary diaphragm valves may flow in both directions in the intended position of the lines, but should ensure the convenience of operation and repair.
. Before the unit, clean the valve cavity to avoid dirt blocking or damage to the sealing parts, and check that the connection bolts of each component are tightly fastened.
10. It is necessary to always look at parts touched with the media during operation and to replace fragile parts on a timely and timed accordance with practice.
11. When replacing the diaphragm, be careful not to tighten or loosen the diaphragm.
12. Applied to intermittent running lines, the media should be cleaned and touched during discontinuation in order to extend the service life.
13. When manually manipulating the pneumatic sanitary diaphragm valve, the valve must not be opened and closed with the help of auxiliary levers to avoid too much torque and damage to the drive part or sealing area.
14. Pneumatic sanitary diaphragm valve after maintenance of pneumatic sanitary diaphragm valve, before application, according to the relevant test rules for sealing test qualified after the energy device.
