Abstract: A butterfly valve includes a purge gas flow path supplying a purge gas for preventing inflow of a control fluid into a magnetic fluid sealing portion from a flow path through an insertion hole. The purge gas flow path is provided with an opening and closing valve for opening and closing the purge gas flow path and a pressure gauge for measuring a pressure value in the purge gas flow path, in the stated order from the upstream side. The purge gas flow path is connected to a portion between the magnetic fluid sealing portion and the flow path of the butterfly valve on the downstream side of the pressure gauge, and communicates with the flow path through the insertion hole. The butterfly valve further includes a control device that controls at least the opening and closing valve. The control device is provided with a monitoring program for monitoring a pressure value.

CPC classification number: F16K1/2263
Abstract: A seal for a butterfly valve includes an end cap with an outer tubular side wall surrounding an inner tubular side wall, both extending in the same direction providing a gap therebetween. At least the inner side wall is made from a resiliently deformable material. The end cap abuts a conduit entrance, and the inner and outer side walls extend therein, the outer side wall abutting an inner surface of the entrance of the conduit. A rotatable pivotal disk mounted inside the inner side wall within the entrance is rotatable between a position where the periphery of the disk engages the inner side wall to seal the entrance and a position where the disk is angled relative to the entrance, opening the entrance so a fluid may pass through the conduit. A butterfly valve assembly and a vacuum cleaner including the seal or the assembly are also disclosed.

Abstract: Technologies are generally described for valve assemblies that include a valve body whose inner wall defines two ports and a controllable flow path that extends along the inner wall between the two ports of the valve body. Each port may be fitted with a corresponding gasket. A rotatable member disposed in the controllable flow path of the valve body may include a hemispherical-shaped body with a substantially flat disk-shaped surface portion, and a seal ridge formed about a perimeter of the substantially flat disk-shaped surface portion. During opening and closing operation, the seal ridge may be selectively engaged with either one of the gaskets reducing an initial contact surface, and thereby reducing friction between the rotatable member and the gaskets.

Abstract: A valve and coupling for joining pipe elements has a valve body captured in a central space defined by a plurality of coupling segments attached to one another end to end. The inner surface of the valve body defines a bore. A liner on the inner surface surrounds the bore and forms a seal with a valve closing member. Circumferentially arranged projections on the segments engage and center the valve body within the central space. The liner has lobes that extend axially in opposite directions. The lobes are compressed between the segments and the pipe elements to form a fluid tight seal when connection members are tightened to draw the segments toward the central space and into engagement with the pipe elements.

Abstract: A valve assembly has a stationary valve body and a valve member that is movable relative to the valve body at least from a closed position, in which the valve member cooperates with a valve seat to completely obstruct a fluid path formed through the valve body, to an open position, which allows fluid to flow through the fluid path. The valve member has a disc- or ball-shaped rigid component that is overmolded with a flexible component and at least partially encompasses the rigid component in a circumferential direction to form a ring gasket section.

Abstract: A butterfly valve includes a valve body with an internal flow passage, a seat ring attached to an inner peripheral surface of the internal flow passage, a valve stem rotatably supported by the valve body, and a valve element rotatably supported by the valve body via the valve stem. The valve element has an annular outer peripheral edge surface, and includes, at opposite positions in the direction of the rotation axis on the outer peripheral edge surface, two valve-stem openings for the valve shaft to pass therethrough. The outer peripheral edge surface of the valve element includes two annular opening raised portions each extending along the periphery of the corresponding valve stem openings, and peripheral edge raised portions connecting the two opening raised portions, each having a peripheral edge sealing surface extending along a top thereof, and chamfered surfaces inclined and extending along both sides of the peripheral sealing surface.
