Installation matters of welding vacuum bellows vacuum baffle valve 1. Open the package, firstly check whether the surface of the pneumatic high vacuum baffle valve is intact, check whether the cylinder is intact and without cracks, and check whether the solenoid valve voltage is the same as the voltage when ordering. 2. Check whether the connecting flange of the high vacuum baffle valve is the same as the size when ordering, whether the flange connecting sealing surface and the valve seat sealing surface are lubricated and free of burrs, and check whether the matching O-ring is correct. 3. The valve is connected to the air pipe of the air compressor and the air pump, and the valve is opened and closed by the electromagnetic reversing valve. Test to see whether the valve plate can be opened and closed normally. If it is opened and closed normally, the valve can operate normally. 4. After checking the above points, the pneumatic high-pressure valve can be installed. Before installation, check whether the valve cavity of the pneumatic high-vacuum baffle valve has residual particles or remnants. Next, clean up the flange surface and channel of the molecular pump interface flange and the vacuum equipment interface flange, including dirt, oil stains, and oil residues (wipe with a clean cloth with alcohol and banana water). 5. After the flange surface is clean and clean, apply a small amount of vacuum grease on the flange surface, then put the O-ring or the center bracket into the sealing groove, and correct the two flanges at the joint surface to be flat and correct. Using bolts, calipers, Use clamps and other methods for connection and fixation."
