A kind of Huff joint of glass steel pipe

Abstract

The invention discloses a half coupling of a glass steel tube. The half coupling is composed of two half pieces which are connected by use of a bolt; limiting flangings are formed at the two ends of the half coupling; a groove is formed in the radial direction of a jack. The half coupling is capable of sliding in the axial direction by a certain distance and also capable of deflecting by a certain angle, and has the advantage of flexible connection; meanwhile, the limiting devices are used for preventing axial separation, and therefore, the half coupling has the advantage of rigid connection.

Description

technical field [0001] The invention relates to the technical field of glass pipes, in particular to a Huff joint of glass pipes. Background technique [0002] At present, the intake and drainage FRP pipes need to be installed underwater, and the usual connection methods are double "O" ring sealed socket connections or flange connections. [0003] The advantage of the double "O" ring-sealed socket connection is that the socket can slide and deflect axially for a certain distance in the socket, which is called a flexible connection. The disadvantage is that the axial force is greater than the frictional resistance between the pipe and the soil, and there is no thrust at the end When the pier is pressed, the socket will come out of the socket. [0004] The flange connection is a rigid connection without any axial and deflection adjustment, and the cost is relatively high. Contents of the invention [0005] The technical problem to be solved by the present invention is to p...
