The control device can be switched between a blocking position in which the connection between the first line segment and the second line segment is blocked, and a flow position in which the connection between the first line segment and the second line segment is open. The control device 32 includes a control body 30 rotatably supported between the blocked position and the flow position. The control body can be positioned at a distance between the first line segment and the second line segment. In the control body, an intermediate line segment is embedded, and the first line segment can be connected to the second line segment via the intermediate line segment. The control body 30 is adjustable for its position via translationally adjustable operating means, and is provided with a direction converting mechanism 96.

Abstract: A technique facilitates connection of tubulars along a tubing string via a linear motion. A first tubular is provided with a first connector end having a non-circular transverse cross-section, and a second tubular is provided with a second connector end having a corresponding non-circular transverse cross-section. The non-circular cross-section and the corresponding non-circular cross-section are designed to matingly engage when the first and second tubulars are moved linearly toward each other to form a tubing string. A seal is provided to seal the first connector end with the second connector end once linearly engaged. A locking mechanism may be employed to linearly lock the first connector end with the second connector end.

Abstract: A one-piece pipe coupling device for commercial water-closets. The pipe coupling consists of a one-piece replacement for a multi-part spud-gasket assembly. The device may be used to couple a toilet bowl fixture and supply pipe of an exposed flush valve. The device is constructed from a single-part resilient body including an internal passage extending between a first end and a second end of the resilient body, the internal passage configured to receive an end portion of the water supply pipe and form a water-tight seal by compressive engagement therewith.

Abstract: A low temperature fluid dual structure pipe includes: an inner pipe through which a low temperature fluid flows; and an outer pipe externally fitted to the inner pipe with a sealed tubular space therebetween. An inactive gas having a melting point and a boiling point each of which is equal to or higher than a temperature of the low temperature fluid is filled in the tubular space between the inner pipe and the outer pipe. When the low temperature fluid flows through the inner pipe, the inactive gas is liquefied or solidified, and therefore, at least one of a liquefied inactive gas layer and a solidified inactive gas layer is formed on an outer peripheral surface of the inner pipe. As a result, a pseudo vacuum layer that is in a substantially vacuum state is formed in the tubular space.
