Abstract

A corrugate pipe connection device according to the present invention is completely coupled, by interposing a clamping ring between a nut and a socket; first-screw-coupling the nut and the socket; inserting, into an inside of the nut, an end portion of a corrugate pipe having ridges and valleys alternately and continuously formed thereon; and then second-screw-coupling the nut and the socket suchthat an inner side portion of the clamping ring is inserted into the valleys of the corrugate pipe and an end portion of the corrugate pipe is compressed. Accordingly, the corrugate pipe connection device can be coupled in a simple and easy manner while achieving an excellent sealing effect.

Description

technical field [0001] The present invention relates to a bellows connection device and a coupling method thereof, and more particularly, to a bellows in which a socket and a nut are coupled to one end of the bellows so that the bellows can be connected to a fluid moving unit, an opening / closing valve, etc. Connection device and connection method thereof. Background technique [0002] A connection device for bellows according to the prior art is disclosed in KR 2014-0025124. Such as figure 1 As illustrated in FIG. 3 , the disclosed bellows connection device includes: a bellows 1; a nut 2 inserted into the bellows 1 so as to surround the outer peripheral surface of one side of the bellows; a clamping ring 3, the The inner part of the clamping ring 3 is inserted into a valley formed in one end of the bellows 1 to prevent the movement of the nut 2 in a given direction; and the socket 4 is configured to be tightened to the nut 2 while The distal end 5 of the bellows 1 is pres...
