摘要： A vented draining device configured to be affixed to an existing container, such as a plastic beverage bottle with a threaded neck finish. The vented draining device allows for the attachment of a tube for the connection of the draining device to a fluidic system for draining while venting air from the existing container. Apertures in the draining device provide venting for the exhaust of air which is displaced by the fluid which is drained into the container.

摘要： An isolation valve assembly having a valve body (22) provided with an inlet (23) and an outlet (24), fluidly connected by a fluid passageway (25), and an isolation valve (26, 27) that is operable to selectively open or close the fluid passageway. A vent is fluidly connected to the fluid passageway and a vent valve (34) is operable to open and close fluid communication between the fluid passageway and the vent. The vent valve comprises a stem (36) with a sealing member (37) and is operable between an open position, in which the sealing member is disposed such that the fluid passageway and the vent are fluidly connected and a closed position in which the valve stem extends across the fluid passageway and the sealing member seals the vent from the flow passageway.

摘要： The sanitary diverter valve (70) is for use in a drying system or powder conveying system including conveying lines and a purge line of a purge arrangement. The sanitary diverter valve comprises a valve housing (71) with a number of openings (72, 73, 74) configured to be connected to respective lines of the system. The valve housing (71) is substantially cylindrical and includes a first opening (72), a second opening (73) and a third opening (74). Furthermore, the diverter valve (70) comprises a rotatable diversion member (75) provided with a flow channel (76) having a first end (76a) and a second end (76b), an open space (77) being defined between the valve housing (71) and the rotatable diversion member (75). The rotatable diversion member (75) is configured to be rotated between a first position and a second position to allow that fluid communication is selectively provided between the first opening (72) and the third opening (74) and between the first opening (72) and the second opening (73) of the valve housing (71).

摘要： A dispenser for delivering a liquid from a supply bottle. The dispenser has a base with a base foot. A tubular support is attached to the base foot. The tubular support extends vertically from the base foot. A rim is attached to the tubular support. The rim extends horizontally from the tubular support at a location above the base foot. The rim is vertically aligned with the base foot. A removable bottle collar engages with the rim. The removable bottle collar is adapted to engage and support the supply bottle inverted and positioned within the rim. The removable bottle collar has a center aperture where a mouth of the supply bottle extends there through.

摘要： A purge valve comprising a valve body having a first primary loop port, a second primary loop port, a first secondary loop port and a second secondary loop port is provided. The secondary loop ports are disposed at respective ends or a linear secondary loop portion of the valve body. A primary loop portion of the valve body is formed by a pair of closely spaced tees extending from the secondary loop portion. At least one main valve portion is disposed in a first one of the tees. A drain/venting valve portion extends from the main valve portion. A portion of the secondary loop portion between the tees is shared with the primary loop portion in which flow in a primary loop and a secondary loop are hydraulically separated. A second drain/venting valve portion may be provided in a second one of the tees.

摘要： A relief vent including a vent body having an opening configured to be in communication with the internal volume of a tank. The relief vent further includes a movable portion that is movable relative to the vent body. The movable portion or the vent body includes a base and a sealing member coupled thereto. At least part of the sealing member is elastically deformed to press at least a portion the sealing member against the base. The portion of the sealing member pressed against the base is positioned to sealingly engage the other one of the movable portion or the vent body.

摘要： An anti-siphon device for a flush valve having an air-inlet sealing diaphragm, a diaphragm bracket with an air inlet, a flex sleeve, a venting bracket, and an offsetting spring. The deformation power of the air-inlet sealing diaphragm is comparatively small. When compared with existing anti-siphon reflux devices, this anti-siphon device has a very low current pressure loss and can prevent leaking. When the anti-siphon device is applied in heating and plumbing devices, such as a flush valve, the current pressure can be retained and thus satisfactory flush effect is achieved.

摘要： A vent apparatus is opened to allow free flow of fuel vapor from a vehicle fuel tank through the vent apparatus to a fuel vapor recovery canister during tank refueling until a predetermined level of liquid fuel is reached in the vent apparatus. Once refueling has been completed, the vent apparatus is closed to block or limit further flow of liquid fuel to the vent apparatus. At the same time, fuel vapor discharge passageways in the vent apparatus that had been closed once the fuel tank had been filled to a predetermined capacity with liquid fuel are reopened so that fuel vapor can flow freely from the fuel tank to the canister even though the volume or height of liquid fuel in the fuel tank has not decreased since the tank was filled during refueling.
