摘要： A pipe joint and a joint connection device have simpler configurations while preventing fluid leakage and absorbing misalignment of shaft centers. A pipe joint includes a male joint and a female joint into which the male joint is inserted. The male joint has a male joint main body and a cap that is fixed at a base end of the male joint main body, with a male joint O-ring interposed between the cap and the male joint main body. The cross-section diameter of the male joint O-ring is 3 to 10 mm, and a clearance-between the male joint main body and the cap is 3 to 13% of the cross-section diameter of the male joint O-ring.

摘要： Provided is a rotary joint capable of lubricating a sealing surface of a mechanical seal forming a fluid passage through which a gas flows using a liquid even when the liquid flows through only one fluid passage. A rotary joint 1 includes a plurality of mechanical seals 7 provided in an axial direction in an annular space A between a case body 2 and a shaft body 5 to form a first intermediate flow passage 41 that connects a first outer flow passage 31 and a first inner flow passage 61 of a first fluid passage 11 through which a liquid flows to each other and form a second intermediate flow passage 42 that connects a second outer flow passage 32 and a second inner flow passage 62 of a second fluid passage 12 through which a gas flows to each other. The first outer flow passage 31 and the first inner flow passage 61 are open at mutually different positions in the axial direction with the second intermediate flow passage 42 interposed therebetween, and connects an opening of the first outer flow passage 31 and an opening of the first inner flow passage 61 in the first intermediate flow passage 41. The first intermediate flow passage 41 is formed such that a liquid flowing through the first intermediate flow passage 41 lubricates first and second sealing surfaces 71a and 72a of the mechanical seal 7 forming the second intermediate flow passage 42.

摘要： An air-to-air aftercooler (ATAAC) configured to cool compressed air from an air compressor is disclosed. The ATAAC may comprise a header at a cold end, and a plurality of core tubes. Each of the core tubes may have a first end and a second end. The ATAAC may further comprise a plurality of grommets each connecting the second end of one of the core tubes to a slot of the header. Each of the grommets may include an inner surface contacting the core tube and an outer surface contacting the slot of the header. The inner surface of the grommet may include radially-inwardly projecting regions contacting the core tube, and depressed regions providing clearance between the grommet and the core tube.

摘要： A decompression heat-insulating pipe structure that can exhibit the desired heat-insulating performance and is easy to assemble. In the structure, a space between ends of inner and outer tubes is decompressed. The outer tube includes a first flange, which extends radially inward from an axially one end thereof, and a second flange, which extends radially outward from the axially other end thereof. The inner tube includes a third flange, which extends radially inward from an axially one end thereof and is opposed to the first flange at an axially inward position of the first flange, and a fourth flange, which extends radially outward from the axially other end thereof and being opposed to the second flange at an axially outward position of the second flange. First and second elastic seal members are disposed between the first and third flanges and between the second and fourth flanges, respectively.

摘要： An assembly for fastening a conduit to a flashing structure that is typically secured to a shingled roof. The apparatus includes an adjustable clamp that can be secured to a cap on the flashing. A conduit is laid on top of the cap and the adjustable clamp is positioned on top of the conduit and is snapped in place along the perimeter of the cap. An adjustable bolt is threaded through the top of the clamp with a curved saddle that resides beneath the clamp and conforms to the shape of the conduit's outer surface. The bolt can then be adjusted to tighten the conduit to the cap. An exemplary use of the clamp involves securing conduit for running electrical wiring throughout a solar panel array.
