摘要： A hydrant device includes a faucet body, a rotation shaft, an upper rotation cap, a check valve, a switch valve, a lower fixed cap, and a water intake seat. The faucet body is provided with a rotary knob connected with the rotation shaft which is connected with the upper rotation cap. A first elastic member is biased between the rotation shaft and the upper rotation cap. A second elastic member is biased between the upper rotation cap and the check valve. The check valve is provided with a stop face. The switch valve is combined with the upper rotation cap. The water intake seat is mounted on the faucet body. Thus, the stop face forms an anti-reverse state to seal the switch valve, thereby preventing water from being gathered in the switch valve.

摘要： Disclosed herein is a valve apparatus for vehicles that is configured such that the sealability of a valve body can be markedly enhanced. The valve apparatus includes a valve body, a valve member and a sealing unit. The valve body is provided with at least two ports and has an internal space communicating with the ports. The valve member is rotatably installed in the internal space so as to open or close the ports. The sealing unit is provided to seal at least one of the ports. The sealing unit includes a sealing body airtightly installed on an inner surface of the corresponding port, and at least one elastic element integrally provided on a first end of the sealing body. The elastic element axially applies elastic force to the sealing body so that a second end of the sealing body comes into airtight contact with the valve member.

摘要： The emergency shower includes a discharge outlet pivotable between a first non-use position and a second deployed position about a rotary union, for dispensing water therefrom. A ball valve is positionable between a first flow restricting position and a second flow permitting position, when the discharge outlet pivots between the first non-use and second deployed positions. A linkage system actuates ball valve movement when the discharge outlet pivots, by way of a first link pivotally coupled relative to the discharge outlet and movable therewith and a second link pivotally coupled with the ball valve and responsive to movement of the first link, the second link positions the ball valve in the first flow restricting position when the discharge outlet is in the first non-use position and commensurately moves the ball valve to the second flow permitting position when the discharge outlet pivots to the second deployed position.

摘要： A freeze tolerant ball valve for controlling the direction of expansion of freezing water within the ball valve is disclosed. The valve includes valve body inlet and the valve body outlet, and a spherical-shaped gate that has an axial fluid passage that extends through the spherical-shaped gate. The spherical-shaped gate can be rotated to block fluid communication between the valve body inlet and the valve body outlet. The valve body also has a first sidewall that is of a first sidewall thickness, and a sidewall having a boss that supports a concave cap that has a bottom wall that is of a bottom wall thickness, the bottom wall thickness being substantially thinner than the sidewall thickness. The cooperation of the passage through the spherical- shaped gate, the first sidewall with its first sidewall thickness positioned opposite to the bottom wall of the concave cap results in a valve that directs the effects of freezing on to the concave cap, which would fail first in the event of freezing. The cap can be easily and quickly replaced in the event of failure.

摘要： Plumbing fixtures with a valve actuator for automatically controlling pivoting of a flush valve, and methods of calibrating movement of the flush valve, are disclosed. The motor of the valve actuator may be positioned between the bowl of the fixture and a leg of a trapway to provide compact assembly. A belt drive laterally extending along the trapway links the motor to the flush valve. The method of calibrating includes establishing stop points which are at positions of less resistance than hard stop positions.

摘要： A valve for an infusion pump device comprising a pump connection fluidly connected to a piston pump, an infusion site connection fluidly connected to an infusion set, and a reservoir connection fluidly connected to a reservoir is presented. The valve is in a first state (I) when the pump connection is fluidly connected to the infusion site connection and the reservoir connection is sealed closed and in a second state (II) when the pump connection is fluidly connected to the reservoir connection and the infusion site connection is sealed closed. The valve comprises one or more conduits, grooves, and/or recesses connected to environment and arranged so that no path exists within the valve between the infusion site connection and the reservoir connection that does not cross at least one of the conduits, grooves, and/or recesses, establishing a drain, independently if a path is closed during normal operation of the valve.

摘要： A sealing microsawtooth ring joint, made between a toothed seating surface and a full plain seated surface by a microsawtooth ring with its tooth crest on the seating surface being a cutting edge whose corner or whose crest angle is about 90°˜120°, with its tooth height Zt being about 10˜20 times the roughness Ra of the seated surface, and with the ratio of its tooth pitch Xs to its tooth height Zt being 20˜500 to ensure that the tight joint has a microcosmic line contact followed by a surface contact or to ensure that the tight joint has both such a line contact as to be able to provide a necessary seating stress locally and such a surface contact as to be able to protect the line contact from being excessively pressed to get blunt or disappeared, can be used either as a pressure-tight joint or as a self-energizing tight joint of any two surfaces such as flats to flats, cones to cones or spheres, spheres to spheres or cones etc., thus simplifying and unifying the designing, calculating, manufacturing, selecting, installing and maintaining of fussy gaskets for a tight joint of flat surfaces, avoiding the lapping of formed jointing surfaces without using soft gaskets, increasing the reliability of tight joints and the utilizing coefficient of natural resources. The sealing microsawtooth ring joint can still have an extra sealing reliability and safety sensation by selectively adding one of four basic gland seals.
