Housing type pipe joint

Abstract

A housing type pipe joint 1 for connecting a pair of pipes comprising: a pair of housings 3 each including a housing body 4 and a flange portion 5; fitting portions 4a located in parallel on the inner surface of the housing body to fit with the pipes P, each fitting portion including one stepped section 4a3 angles diagonally relative to the center axis line C; and a positioning member 6 on opposed surface of the flange portion, the positioning member engaging with the other positioning member to position the housings at a first or second position when one housing is rotated on a plane about asymmetric point Sy; at the first position the distance between the opposed fitting portions is the closest and the pipes are movably coupled; and at the second position the distance is the largest and the pipes are fixedly coupled to the housings.

Description

technical field [0001] The present invention relates to a shell type pipe joint for butt ends of pipes to be connected to each other. Background technique [0002] Such as Figure 12 The shell type fittings shown in are previously known. This shell type pipe joint 100 includes a pair of shells 300 connected to each other. Each of the cases 300 includes a substantially semicircular case body 400 and flange portions 500 extending radially outward from both ends of the case body 400 . A pair of pipes P has a circumferential groove Pa formed on pipe ends of the pair of pipes, and are butted against each other to form a connection portion. The pair of casings 300 surround and are connected to the connection portion to interpose an annular gasket 600 between the pair of casings 300 and the connection portion. Bolts 800 are inserted into bolt holes formed in flange portions 500 facing each other, and nuts 900 are tightly screwed onto the bolts 800 . Accordingly, the shell type ...

AI Technical Summary

Problems solved by technology

This results in an increased number of man-hours to maintain the housing at the worksite and reduces operational efficiency

Also, there is the issue of providing storage space

[0014] In addition, the shell-type pipe joint disclosed in Patent Document 3 can satisfy movable connection and fixed connection, but has a problem of operational efficiency that needs to attach / detach a plug, needs to connect the plug to a recess in the housing in a predetermined direction, and the like.

For this reason it may not provide a secure connection when the plug is connected in the wrong direction
