摘要: A valve suitable for a fuel tank may include a valve housing having a housing part, and a float configured for closing a vent opening, the float being movably arranged inside the valve housing along a middle longitudinal axis running in an axial direction upward or downward. A lower section of the float faces away from the vent opening and faces toward the housing part of the valve housing. At least one spring element is at least partially arranged in or on the housing part and/or is at least partially formed by the housing part. The spring element contacts the float at least when the float moves downward in the valve housing.

摘要: The discharge valve unit includes: a valve case configured to be detachably attached to the housing and including a second reservoir for liquid configured to communicate with the first reservoir when the valve case is attached to the housing; and a second valve mechanism disposed in the second reservoir and including a second discharge hole having a larger opening diameter than that of the first discharge hole and a second valve member accommodated in the second reservoir and configured to open and close the second discharge hole. The second valve mechanism includes a spring configured to bias the second valve member in a valve opening direction. When a pressure of the second reservoir increases to a predetermined value, the second valve member closes the second discharge hole against a biasing force of the spring.

摘要: A valve body, including a first cavity, a second cavity communicated with the first cavity through a second water inlet of the second cavity, a valve core and an elastic reset member; the valve core, arranged in the first cavity and coaxial with the second water inlet, includes a piston and a first ejector rod being coaxial with the piston; the piston is configured to open or close the second water inlet; the elastic reset member is configured to press the valve core to move in the axial direction to close the second water inlet. A self-locking level control valve is adopted. The water purifier achieves no reactive power loss, low emission and safe water quality, avoids frequent startup of the water purification system, and solves the technical problem of the “first glass of water” brought by the ultra-low pressure reverse osmosis pumpless water purification system.

摘要: In at least one aspect of this disclosure, a shut off valve for an ecology fuel return system can include an inlet for receiving a fluid, an outlet for effusing the fluid, and a valve member configured to move between an open position such that the valve member allows fluid to effuse from the outlet and a closed position such that the valve member prevents fluid from effusing from the outlet. The valve member can include a pressure deflector configured to prevent fluid flow from biasing the valve member toward the closed position.

摘要: A one-piece valve cartridge assembly for controlling fluid flow in a vehicle has a valve actuator, first and second valve members and a valve cap. The actuator has a piston which is extendable and retractable along a longitudinal axis, with the valve members being provided at opposite ends of the actuator body. The valve cap includes a central, longitudinally extending sleeve portion to receive the free end of the piston with an interlocking fit. The piston may have an annular groove which interlocks with an annular bead inside the sleeve portion of the valve cap. The interlocking fit prevents separation of the assembly components during manufacturing and shipping, with axial alignment of the assembly is maintained by a close fit between the piston and the sleeve portion.

摘要: A backflow valve assembly for preventing gas and backup waste from escaping a floor drain includes a tube that is configured to fluidically couple to a drain line. A pipe is coupled to and axially positioned in the tube. The pipe has upper and lower ends that are closed. At least one gasket is coupled to an inner surface of the pipe and defines upper and lower chambers. Penetrations are positioned through the pipe to allow flow of gasses and liquids into the pipe. First and second balls, which are less dense than water, are positioned in the upper and lower chambers, respectively. The first ball prevents escape of the gasses from the tube. The first ball floats to open the gasket to permit the flow of the liquids to the drain line. The second ball floats to close the gasket to prevent escape of waste from the tube.

摘要: A way out valve for urinal with double little ball, characterized by being formed by two chambers, one lower and one upper, with small balls that move to let the liquids deposited in the urinal pass or seal and prevent the exit of gases of drainage; the upper chamber has truncated cone base that, when it has liquid, floats the ball that is in this chamber and allows the liquids to pass to the lower chamber; the lower chamber has an inclined roof that allows, on its upper face, to slide the liquids up to the vertical passage that transports the liquids to the lower chamber, passing them through the lower orifice; the lower chamber has a central perforation in its inclined floor where the liquids of this chamber pass to the liquid conduit towards the drainage.

摘要: A water shut-off device is disclosed. The water shut-off device has an inlet port and an outlet port. The water shut-off device includes: a housing fluidly connected to the inlet port and the outlet port, the housing having an opening at its upper end and including: a valve for switching the device between an open configuration and a closed configuration, the valve permitting flow of water through the device in the open configuration and prohibiting flow of water through the device in the closed configuration; a gear wheel secured to the housing and operatively coupled to the valve, the valve being actuated by rotations of the gear wheel; and an anchor in mechanical communication with the gear wheel, the anchor including: a container for receiving water flowing through the opening; and at least one pallet connected to the container, the at least one pallet being configured to catch against one or more teeth of the gear wheel, the anchor being rotatably mounted at a fixed pivot in the housing such that the anchor swings about the pivot as water collects in the container, the swinging of the anchor about the pivot causing the at least one pallet to alternately catch and release a tooth of the gear wheel, thereby causing the gear wheel to rotate in a first direction.
