A liquid dispensing faucet includes first and second inlet flow passages that are isolated from each other, and first and second valve chambers respectively in fluid communication with the first and second inlet flow passages. First and second valve elements are located respectively in the first and second valve chambers and respectively control flow of liquid from the first and second inlet passages through the first and second valve chambers. First and second outlet passages are respectively in fluid communication with the first and second valve chambers for respectively receiving and dispensing liquid from the first and second valve chambers. A handle is operatively connected to both the first and second valve elements for selectively opening the first and second valve elements to allow flow of liquid through the first and second valve chambers when the handle is moved from a first position to a second position.

Provided is a simpler, more efficient, and more reliable latch valve. The latch valve includes an inflow path and an outflow path formed in a housing; a solenoid having a coil wound thereon; a permanent magnet positioned at an upper portion of a plunger and latching the plunger when the plunger is lifted; a spring positioned between the permanent magnet and the plunger; a support body having an inlet connected to the inflow path and an outlet connected to the outflow path; a diaphragm having the support body inserted therein; and the plunger lifted or lowered by a magnetic force induced by the coil to open and close the outlet, wherein an additional outflow path constantly communicating with a space part between the support body and the plunger is provided to allow a flow to be generated in the additional outflow path even when the plunger is closed.

An apparatus, system, and method for raising water is provided. The apparatus includes at least one container movable between at least a descended position and a ascended position within a body of water. A non-water-permeable membrane is positioned within the at least one container, wherein the membrane is movable within an interior compartment of the at least one container to separate the interior compartment into at least a first and a second portion. At least one vent structure is within a wall of the at least one container, wherein movement of the membrane controls a flow of water through the at least one vent structure and into at least one of the first and second portions.

A beverage dispenser for dispensing a carbonated beverage includes a housing defining an interior volume and having a first surface proximal to the beverage source and a second surface distal to the beverage source. The beverage dispenser includes a conduit in fluid communication with the beverage source entering the first surface of the housing and terminating proximate the second surface of the housing. The dispenser includes a flow rate controller including a processor disposed within the interior volume of said housing and a subsurface dispensing nozzle in fluid communication with the terminal end of the conduit. The dispenser also includes a user interface including user-selectable indicia for providing data to the processor. The flow through the conduit to the subsurface dispensing nozzle is compensated to maintain substantially hydraulic beverage flow within the conduit, and is based on data provided to the processor by a user operation of the user interface.

摘要:
The invention relates to a device (100) for actuating a process valve that has a first cylinder and a second cylinder, comprising at least one first control valve arrangement (102) that has at least a connector for a line to the first cylinder of the double-seat valve, an intake-air connector and an exhaust-air connector, and comprising a second control valve arrangement (103) that has at least a connector for a line to the second cylinder of the double-seat valve, a connector for an intake-air line and a connector for an exhaust-air line, wherein separate exhaust-air lines (104, 105) are provided for the first and the second control valve arrangement (102, 103).
摘要:
A backflow prevention device including an upstream shutoff valve configured to allow a user to control the water flow stream through the housing. The upstream shutoff valve includes an obstruction. The obstruction is configured to prevent water flow at a first position and allow water flow at a second position. The obstruction is also configured to rotate about an axis of rotation between the first position and the second position. The upstream shutoff valve also includes a seal. The seal is configured to sealingly engage a sealing surface in the housing at the first position. All points of engagement between the obstruction seal and the sealing surface are located downstream of the axis of rotation of the obstruction.
摘要:
A check valve module. The check valve module includes an orifice, where the orifice is configured to allow the water flow stream through the check valve module. The check valve module also includes a clapper. The clapper is configured to allow the water flow stream through the orifice when open and prevent the water flow stream through the orifice when in a closed position by mating with the orifice. The check valve module further includes a fulcrum apparatus about which the clapper is allowed to rotate, a rotational constraint apparatus which directs the rotation of the clapper and a lateral constraint apparatus which directs the motion of the fulcrum toward and away from the orifice.
