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： In order to maintain airtightness by a ferrule even by use of a general-purpose tool and to be capable of releasing airtightness by the ferrule if necessary, a pipe joint (Ja) includes a ferrule (33) receiving an axial pressing force from a fixing member (66a) screwed in a clamping direction thereby to airtightly seal a gap between an inner periphery of the joint body (16) and an outer periphery of a pipe (P) when the fixing member (66a) is rotated in a clamping direction to be screwed in, a loosening male thread (68) formed on an outer periphery of the fixing member (66a) and threaded in a direction opposed to a direction in which the joint body (16) and the fixing member (66a) are threaded, a loosening tool (130) screwable into the loosening male thread (68), and a pressure receiving portion (39) abutting against the loosening tool (130) thereby to prevent further screw-in when the loosening tool (130) is screwed into the loosening male thread (68) and rotated in the direction opposed to the clamping direction of the fixing member (66a).
摘要翻译：管接头（Ja）为了即使使用通用工具也能够通过金属箍保持气密性，根据需要能够通过套箍释放气密性，因此具备：从固定部受到轴向按压力的套圈（33）（66a）沿夹紧方向旋拧，从而当固定构件（66a）沿夹紧方向旋转到接合体（16）的内周边在固定部件66a的外周形成有螺纹部，该螺纹部68在与接头体16和固定部件66a的螺纹方向相反的方向上形成螺纹，可旋入松动阳螺纹（68）中的松动工具（130）和抵靠松动工具（130）的压力接收部分（39），从而防止当松动工具（130）拧入松开阳螺纹（68）并沿相反的方向转动 d移动到固定构件66a的夹持方向。

摘要： In order to improve the reliability of sealing performance, a pipe joint (Ja) includes a cylindrical clamping member (32) screwed into a joint body (16), a ferrule (33) receiving an axial pressing force from the clamping member (32) screwed in a clamping direction, thereby airtightly sealing a gap between an inner periphery of the joint body (16) and an outer periphery of a pipe (P), a cylindrical fixing member (66a) constructing the clamping member (32) and abutting against the ferrule (33) to apply a pressing force to the ferrule (33), a clamping nut (36) constructing the clamping member (32) and having an outer periphery formed with a non-circular fitting portion (48) and receiving a screw-in force in the clamping direction, thereby imparting to the fixing member (66a) a pressing force to the ferrule (33) side, and a locking unit (41) preventing the fixing member (66a) from displacement in a direction such that the ferrule (33) is released from the pressing force applied by the fixing member (66a).
