Abstract: Provided is a joint structure with which a pipe can be disconnected without moving the pipe in a longitudinal direction thereof, even if the pipe is not machined. A first sleeve 2 has an inner cavity into which a pipe 100 is inserted, and one end part of the first sleeve comes into contact with a joint body 1. A second sleeve 3 has a hole into which the pipe 100 is inserted, and one end part of the second sleeve comes into contact with the other end part of the first sleeve. A nut 4 covers one end part of the joint body 1, the first sleeve 2, and the second sleeve 3, and the nut is threaded onto the joint body in a state of pressing against the surface of the second sleeve 3 on the side opposite from the first sleeve 2.

Abstract: A valve includes a housing defining therein a channel, a valve seat on an inner surface of the housing at a middle of the channel, a valve body member seated on and unseated from the valve seat to close and open the channel, and a stem spaced from the valve seat and rotatable around a first axis parallel with an opening surface of the valve seat. The valve body member and the stem respectively have a restricting hole and a restricting projection mutually slidably engageable to form a cam mechanism. The cam mechanism, in conjunction with rotation of the stem, reciprocates the valve body member between the seated position and the unseated position, and rotates the valve body member to be in a posture along a flow direction of a fluid flowing through the housing at the unseated position.

Abstract: A fitting includes: a first member; a second member coupled by screw coupling with the first member; and a ferrule placed in an accommodation space between the first member, the second member, and a pipe. The ferrule has a rising portion including a first end portion, a pressed portion located closer to a second end portion than the rising portion, and an intermediate portion including a portion where an inner diameter is greater than the first end portion and the second end portion, the intermediate portion connecting together the rising portion and the pressed portion. The first member has a first tapered inner circumferential surface, which is an inner circumferential surface having a tapered shape, to be in contact with the first end portion of the ferrule. The second member has a pressing portion for pressing at least a portion of the pressed portion of the ferrule. The accommodation space provides a clearance for accommodating the ferrule and allowing the rising portion to rise so as to increase an angle of the rising portion.

Abstract: To make it possible to remove pipe members that are connected together by moving the pipe members in a radial direction, for example, without moving the pipe members in an axial direction, a pipe joint comprises a series of unit members each of which is rotatably connected to the adjacent one another and a fastener for connecting the unit members locating at both ends. A pair of the pipe members take a centering posture or a posture equivalent to the centering posture by engaging the flange portion of a pair of the pipe members with both axial sides of the unit members. A pair of the pipe members are connected together in the centering posture by connecting the unit members locating at both ends using the fastener so as to make the unit members in an annular state and by fastening the fastener.
