The invention relates to a mixing cartridge (1) for generating mixed water with a mixing temperature, having a hot water inlet (2) for hot water, having a cold water inlet (3) for cold water, having a mixing chamber (4), in which the hot and cold water can be mixed, and having a mixed water outlet (5) through which the mixed water can leave the mixing cartridge (1). According to the invention, the mixing cartridge (1) has at least one vortex element (6), which is arranged and/or designed in such a way that the water flowing through the mixing cartridge in a flow direction can be made to rotate, such that the water can form a water vortex.

A control valve for faucet may comprise a control valve, a balancing valve, a water outlet unit, and a faucet body. A lower end of the control valve has a water inlet chamber and a water outlet chamber, and the balancing valve secured inside the water inlet chamber comprises a first shell and a second shell which are formed symmetrically and are configured to fit together to secure a pressure regulator therein. The water outlet unit secured inside the water outlet chamber has a first through hole, and a lower end thereof comprises a lower sealing ring which covers around a lower edge of the water outlet chamber. When control valve connected to the faucet body, the lower sealing ring only will be pressed downwardly instead of being twisted thereby reducing the possibility of damage or deformation and improving the strength of structure and the leakproof effect.

A plumbing fitting includes a housing and a missing valve. The housing includes a first aperture, a second aperture, a third aperture, and a mixing chamber in fluid communication with the first aperture, the second aperture, and the third aperture. The mixing valve is disposed within the housing. The mixing valve includes a first flow control valve that is configured to control a first flow of fluid from the first aperture to the mixing chamber.

A hot water valve assembly is disclosed including a dual inlet housing having a cold water inlet and a hot water inlet, a thermostatic mixing cartridge disposed within the dual inlet housing, an inner conduit disposed adjacent to and in fluid communication with the dual inlet housing and a shell including a mixed water outlet that is connected to and in fluid communication with the inner conduit.

A faucet assembly including a faucet body having a spout, a base, and hot and cold water flow control valves. The base houses a thermostatic mixing cartridge that tempers hot and cold water and has passageways that place tempered water from the thermostatic mixing cartridge and a cold water passageway in selective fluid communication with the outlet of the spout. During use, mixed water from the thermostatic mixing cartridge is regulated by the hot water control valve, cold water is regulated by the cold water control valve, and both the mixed water and the cold water are further mixed at a juncture of the mixed water passageway and the cold water passageway prior to exiting the faucet assembly via the outlet of the spout.

A hot water supply device includes a heater, a water channel, a mixing valve unit, and a circulation mechanism. The mixing valve unit has a valve member and a drive unit configured to drive the valve member to change a mixing ratio of supply water heated by the heater and unheated water. The circulation mechanism has: a connection passage that connects the water channel to the heater by being branched from a part of the water channel between the mixing valve unit and the heater; an on-off valve that opens and closes the connection passage; and a pump configured to return the supply water remaining in the water channel through the connection passage to the heater. A drive amount acquisition unit acquires a drive amount of the drive unit, and a controller controls the circulation mechanism based on the drive amount acquired by the drive amount acquisition unit.

Improved fluid supply assemblies for fluid systems are provided. In exemplary embodiments, the present disclosure provides for improved fluid supply assemblies and related features, systems and methods of use. More particularly, the present disclosure provides for advantageous faucet assemblies (e.g., electrically or mechanically actuated faucet assemblies) having an integrated anti-scald device and having an integrated temperature mixing valve. The present disclosure provides for a faucet assembly having an integrated temperature mixing valve, and/or having an integrated anti-scald device configured to stop the inlet flow of hot water in the event the mixed outlet water temperature exceeds a user-selected set point. Advantageous faucet assemblies of the present disclosure can prevent scalding as defined by ASST; 1070, Improved, convenient and effective systems and methods for utilizing improved faucet assemblies in fluid systems are provided.

A thermal relief valve, comprising a housing having a channel, a first aperture, and a second aperture, wherein the first aperture and the second aperture are arranged symmetrically about a central axis, an actuator within the housing arranged about the axis, a first seal secured to the actuator, the first seal comprising a plurality of apertures, and having a first upwardly facing surface, and a second downwardly facing surface, a first spring arranged between the second surface of the first seal and the housing component, a second seal comprising a first upwardly facing surface and a second downwardly facing surface, the first surface of the second seal positioned on the second surface of the first seal and, a second spring arranged between the second surface of the second seal and the housing, wherein the first seal and the second seal are axially movable by the actuator along the central axis.

A method for controlling air volume including: 1) inputting a target air volume into a microprocessor control unit of a motor controller; 2) starting a motor by the motor controller and allowing the motor to work in a steady state under a rotational speed; 3) recording the torque and rotational speed in the steady state, establishing a functional relation formula Q=F (T, n, V) for calculating the air volume, and calculating an air volume in the steady state; 4) comparing the target air volume with the calculated air volume; 5) re-recording a steady torque after the motor falls on a new steady state under an increased or reduced rotational speed, and recalculating the air volume in the new steady state; and 6) repeating steps 4) and 5) to adjust the rotational speed until the calculated air volume is equal or equivalent to the target air volume.

An aircraft water supply system supplies water to a water discharge port in an aircraft. A cold water flow path supplies cold water to the water discharge port. A hot water flow path supplies hot water to the water discharge port. A first control valve adjusts the flow rate of cold water flowing through the cold water flow path. A second control valve adjusts the flow rate of hot water flowing through the hot water flow path. A temperature sensor detects the water temperature at any point up to the water discharge port. A flow control unit controls the opening/closing state of the first control valve and the second control valve based on the water temperature detected by the temperature sensor.
