    摘要： Described is a check valve having a valve housing, a valve seat, a ball and a spherical loading element. The valve seat is disposed proximate to a first end of the bore. The ball is disposed in the bore and is movable between a closed position in which the ball is received against the valve seat and prevents a flow of fluid through the bore and an open position in which the ball is displaced from the valve seat and allows fluid to flow through the bore. The spherical loading element is disposed in the bore and is movable between the ball and the second end of the bore. The spherical loading element applies a supplemental force to move the ball against the valve seat during closing of the check valve. The check valve provides a low and predictable cracking pressure which does not vary significantly between similarly manufactured valves.

    摘要： A siphon initiator that has a drive cylinder and an inner stopper. The stopper is held in a limited range of motion by a wire guard at one end and the formed end of the drive cylinder at the other end. The inner stopper seals the lower end of the drive cylinder during the siphoning. Both ends of the drive cylinder have hose fittings. In practice, after attaching the hoses, the user inserts one hose into the container holding the liquid. The other hose is inserted into the vessel to receive the liquid. The user then moves the drive cylinder back and forth a few times to initiate the flow of fluid. The motion alternatively seals the hose and opens it in rapid succession, causing the necessary vacuum within the draw hose to pull liquid from the container to begin the siphoning process.

    摘要： A drain valve device includes a base and a control unit removably disposed in the base. The control unit includes a valve and a resilient component positioned between the valve and the base. The drain valve device opens automatically as soon as water entering the base exceeds a predetermined level. The drain valve device shuts automatically as soon as water entering the base is less than a predetermined level. The drain valve device has advantages, namely simple structure, convenient of use, prevention of intrusion of odor and pests, easy to clean, and unlikely to get clogged.

    摘要： A diaphragm device for a check valves is provided. The diaphragm device comprises a diaphragm, adapted to cover at least one orifice, and an operation device, adapted to enable movement of the diaphragm substantially along a length axis of the orifice. The operation device comprises at least one first operation organ and at least one second operation organ. The first and second operation organ in turn each comprises a first portion, and a second portion. The first portion of the first operation organ is adapted to be connected to a check valve housing, and the second portion of the first operation organ is connected to the second portion of the second operation organ. Furthermore the first portion of the second operation organ is connected to the diaphragm and the second portion of the second operation organ is connected to the second portion of the first operation organ. The first operation organ is movable in relation to the second operation organ, and the second operation organ is movable in relation to the diaphragm, for enabling movement of the diaphragm, substantially along the length axis of the orifice. This embodiment could enable the check valve to open a relatively long way by means of a relatively low pressure or flow, at the same time as the deformation of the resilient material could be relatively small since it is deformed in a multiplicity of points and along a relatively long extension of resilient material.

    摘要： A fluid bearing mechanism using a one-way valve with such a simple structure that high processing accuracy is not required. A one-way valve 6 includes a valve base 7; an abutting portion 11 protruding inwardly, formed with a small communication hole 12 in a center thereof; a moveable element 8 which is moveable inside the valve base 7 in an axial direction; and a retaining body 9 for retaining the moveable element 8 between the abutting portion 11 and itself inside the valve base 7. The retaining body 9 includes ventilation grooves 8b, 9c for communicating an inside with an outside of the valve base 7. When the piston 2 is moved toward the compressing direction, the moveable element 8 is shifted toward the inside of the piston 2 due to the inner pressure of the cylinder 1 and its inertial force, thus opening the small communication hole 12.
