  • Patent number: 10787993
    Abstract: This valve device is provided with: a body (10) that has at least one passage (11, 12) for passing a fluid and valve shaft holes (13, 14, 15); a valve shaft (20), which is passed through the valve shaft holes so as to be rotatable; and butterfly valves (30, 40), which are fixed on the valve shaft and are for opening and closing the passages (11, 12). The butterfly valves (30, 40) are disposed so as to close the passages (11, 12) on a downstream side or an upstream side of the valve shaft holes (13, 14, 15) in a flow direction of the fluid. As a result, it is possible to prevent fluid leakage and achieve effective utilization of exhaust heat in an exhaust heat recovery system.

  • Patent number: 10760698
    Abstract: A seal for a coupling joining pipe elements has angularly oriented ramp surfaces on an outer surface. The ramp surfaces are arranged in diametrically opposite pairs which are positioned at the three o'clock and nine o'clock positions at the interface between segments forming the coupling. The ramps are expected to mitigate pinching of the seals between the segments as the segments are drawn together, compressing the seals to form a fluid tight pipe joint.

  • Patent number: 8899257
    Abstract: A shutoff valve, e.g., an engine shutoff valve, is provided which includes a valve body having a fluid, e.g., air, passage and a disc assembly. The disc assembly is pivotable within the fluid passage from an open position to provide for free flow of fluid through the passage, to a closed position to provide a substantially closed off the fluid passage. The disc assembly includes a front disc, a rear disc, and a seal, e.g., a spring energized PTFE seal, disposed between the front disc and the rear disc. The front disc is permanently secured, e.g., welded, soldered or brazed, to the rear disc such that the seal is captured between the front disc and the rear disc.

  • Publication number: 20140312258
    Abstract: An airtightness maintaining structure for a butterfly valve includes a valve element having a rotating shaft and a valve body, a rotation supporting portion having a pivotably supporting member that fits onto the rotating shaft and pivotably supports the rotating shaft, and a rotating shaft seal arranged to contact in a fitting state both an end surface of a member on an outer radial and a surface of a member on an inner side either the rotation shaft or the pivotably supporting member and has an annular portion. In a closed valve state of the valve element, the rotating shaft seal moves radially due to a pressure difference between a high fluid pressure acting on one side of the valve element and a low fluid pressure acting on the other side and contacts both the valve element and the rotation supporting portion on the high fluid pressure side.

  • Patent number: 8814138
    Abstract: A seal used in a valve includes a ring-shaped cartridge. The cartridge has a first portion and a second portion. The first and second portions hold a sealing portion, and the first and second portions have respective first and second curved surfaces adjacent to a sealing surface of the sealing portion. Radii of curvature of the curved surfaces enable an initial point of contact between a flow control member and the cartridge to be on the sealing surface when the flow control member moves to a closed position.

  • Patent number: 8727313
    Abstract: A tri-eccentric valve with a symmetric drain-proof ring includes a valve body, a stem, a valve disk, a waterproof washer, and a drain-proof ring. The valve disk is formed as an asymmetric conical shape. The drain-proof ring is an O ring and is arranged in a stepped recess of the valve disk to seal the waterproof washer; the drain-proof ring is symmetric to the axis of the ring. In assembly state, a periphery of the drain-proof ring resists against an inner wall of the annular seat. The drain-proof ring is symmetrical and thus is easy to be installed to the valve disk without to align the drain-proof ring to a specific angle. Furthermore, it can be designed by computers and is manufactured by machines. When dirt accumulates on the drain-proof ring, it can remove the dirt by directly rotating the drain-proof ring.
