項記載の膨張弁のパイプ組付装置。[Claims for Utility Model Registration] (1) A housing containing an expansion valve and having a pair of connecting holes arranged side by side, an inlet/outlet pipe arranged on one side of the connecting hole, and the inlet/outlet pipe held in the housing. A first holding plate that is attached to the housing, and a second holding plate that holds a high pressure pipe and a low pressure pipe on the other side of the connection hole and presses it against the housing. In an expansion valve pipe assembly device in which nuts are tightened from the plate side and assembled together, a sleeve for externally fitting a bolt is disposed between the housing and the second holding plate, and the sleeve has a larger outer diameter than the bolt. The second plate has an inner diameter of the same size and has a thread formed on its inner circumferential surface that can be screwed into the bolt, and the insertion hole of the housing is formed with a taper whose inner diameter gradually becomes smaller, and the second plate is tightened. When the sleeve is pressed by the second plate and engaged with the insertion hole, the sleeve is deformed to have a smaller inner diameter and engaged with the bolt, thereby attaching the housing to the first holding plate. Expansion valve pipe assembly device. (2) The sleeve has an inner diameter larger than the outer diameter of the bolt, and a screw that can be engaged with the bolt is formed on the inner peripheral surface of the sleeve, as described in claim 1 of the utility model registration claim. expansion valve pipe assembly equipment. (3) Utility model registration claim 1, characterized in that the insertion hole of the housing is a tapered hole.
A pipe assembly device for an expansion valve as described in 2.
