Grooved joint adapter

Abstract

According to one embodiment of the present invention, a grooved joint adaptor comprises: a cylindrical main body having an insertion hole formed in one end to receive an inserted end of a joint pipe,having a groove formed on an outer diameter of the other end, having a guide part formed on inside in a diagonal direction to be connected to the insertion hole, having a first fastening fixation partformed on both sides of the outside, and having a fixation part protruding on an inner circumferential surface; a pipe socket having a second fastening fixation part formed on both sides of the outside to be fastened to the first fastening fixation part by a bolt and having a protrusion part formed on one surface to be inserted into the cylindrical main body through the insertion hole; a pressingring disposed on an insertion hole side of the cylindrical main body, slid along the guide part through the protrusion part upon bolt fastening of the first and second fastening fixation parts, and having both ends spaced apart from each other; a stopper ring disposed on an inner side of the guide part, slid towards the fixation part along the guide part when the pressing ring is moved through the protrusion part, having both ends spaced apart from each other, and having one or more wedge-shaped threads protruding on an inner circumferential surface in a diagonal direction to hold an outer circumferential surface of the joint pipe; and a rubber ring disposed on the inner side of the cylindrical main body to hold the joint pipe through expansion in accordance with compression, having a corrugated part formed on an inner circumferential surface, and having a stopper part protruding towards the inside to be closely adhered to an end of the joint pipe.

Description

technical field [0001] The present invention relates to a grooved joint adapter. In more detail, it relates to a tongue-and-groove adapter for temporarily joining two pipes along the length direction. Background technique [0002] In the connection of pipes, there are permanent connections and temporary connections, and generally, on permanent connections, welding systems are used. In addition, a temporary connection is used in a place where it is attached, a place where disassembly is required, and a tongue-and-groove connection (Grooved Joint) is typically used for the temporary connection. [0003] In other words, the tongue-and-groove connection is a device that uses a groove (Grooving machine) to process a groove (Groove) at the end of the pipe and then uses a tongue-and-groove connection to connect two pipes arranged along the length direction. Refer to Patent Document 1 for It is described more specifically below. [0004] According to Patent Document 1, the tongue...

Problems solved by technology

[0006] However, the tongue-and-groove connection, including Patent Document 1, has the problem of processing grooves at the ends of the pipes first before connecting them.

[0007] In other words, in order to process the groove at the end of the pipe, for example, it is necessary to use the slotting machine disclosed in Patent Document 2 to carry out the work on the spot, but to do the work on the spot not only has inconveniences in various conditions, but also causes problems. Processing fee and transportation fee

[0008] In addition, the proficiency of grooving work is so high that even skilled people have difficulties in processing

Therefore, the tongue-and-groove connection has the problem of high construction cost but low workability and productivity.
