The installation of copper pneumatic valves

copper pneumatic valve installation:
. Pipe thread connection of the pneumatic valve and pipe end of pipe thread connection, including internal thread can be cylindrical pipe thread can also be a tapered pipe thread, and outside thread must be tapered pipe thread.
。 Threaded connections within the pneumatic brake valve is connected to the pipe, the need to control the length of tube outer thread size. In order to avoid excessive screwing in tube so that the top pressure brake in pneumatic valve pipe thread ends, impact deformation and pneumatic valve seat sealing.
。 Pipe thread connection of pneumatic valves, should wrench when install and tighten the screw with the hexagonal or octagonal position, should not be wrench pneumatic valve at the other end of the hexagonal or octagonal position, so as not to cause deformation of pneumatic valve.
。 Pneumatic valve flange and pipe flange connection of the flange is not only consistent with the size, and agree to be nominal pressure.
。 Stop pneumatic valve, brake valve found in the process of installation and commissioning of pneumatic valve stem leakage, tighten packing gland nut can, and pay attention to can't force too much, is limited to not leak.
