摘要： Disclosed is a closing valve A which is provided with a joint function unit (20) reducing a diameter of a clamp ring (40) to connect a pipe (P) and which airtightly locks the joint function unit (20) without reduction in the sealing performance. The joint function unit (20) includes a cylindrical joint body (21) constituting one end of a flow path (13) in a housing (10), a cylindrical clamping member (32) which is threadingly engaged with the joint body (21), the metal clamp ring (40) surrounding the pipe (P) inserted in the joint body (21), a diameter reduction unit (54). The closing valve A is provided with a sealing member (60, 70, 80, 90) which is detachably attachable to the joint function unit (20) and is capable of limiting flow of refrigerant in the joint function unit (20) in non-contact with a seal area (first and second biting portions 49 and 50) of the clamp ring (40) in cooperation with the pipe (P).

摘要： A flareless pipe coupling structure according to one embodiment of the present invention includes a fitting main body 1, a coupling member 2 threaded to the fitting main body 1, and a ferrule 3. The ferrule 3 is located forward of a pipe coupling portion 23 of the coupling member 2. A partition lid 4 serving as a protective member is detachably mounted to the pipe coupling portion 23 to cover the ferrule 3. The partition lid 4, which closes a pipe insertion port 16 when no pipe is connected, can function as a protective member. The partition lid 4 includes, for example, a cylindrical wall 42 having an internal space for accommodating the ferrule 3, and a closing wall 41 that closes one end of the cylindrical wall 42 and closes the pipe insertion port 16 of the fitting main body 1.

摘要： A guide tapered surface 17 of a pipe coupling port 16 has a small diameter portion 17a guiding to a distal end portion 3a of a bite type sleeve 3 to bite into a coupling pipe 5 and a large diameter portion 17b sealing a tapered outer circumferential surface 33 of the bite type sleeve 3 by making close contact with the tapered outer circumferential surface 33 of the bite type sleeve 3. A tilt angle α1 of the small diameter portion 17a relative to a central axis of the guide tapered surface 17 is greater than a tilt angle α2 of the large diameter portion 17b relative to the central axis. Therefore, even when a distal end portion of the coupling pipe 5 is not inserted up to an innermost portion of the pipe coupling port 16, excellent sealing performance is obtained in a portion coupled to the coupling pipe.
