Connection between pressure pipe and housing union

摘要

The connection has a plug portion (23) with a through bore (24) which is mounted on the pipe (26), and fits in a socket (4) which can neither slide nor turn in a bore (2) in the housing (1). A locking device (7,27) prevents the plug pulling out of the socket, and seals (6,32,33) are provided between the plug and socket, and also between the socket and housing. Positive locking devices (13,14,30,31) are also provided between plug and socket, and between socket and housing, preventing them turning in relation to each other. The sleeve can be inserted in the housing, having a locking device (18,19) engaging with the latter to prevent it pulling free.
