Various embodiments of a reverse thermostat for use in restricting hot water in a plumbing system from being delivered to cold water fixtures are disclosed.

The present device includes a slide valve movable in a chamber along an axis between a closed position, in which the slide valve is pressed axially against a fixed seat, and an open position, in which the slide valve is axially separated from the seat and a thermomechanical actuator, which is able to drive the slide valve depending on the temperature of the fluid in the chamber and which includes both a thermostatic element, including a fixed piston, and a body forming a heat-sensitive part of the thermomechanical actuator, arranged inside the chamber The piston being mounted with the ability to move along the axis on the body so that the piston deploys against the body when the thermally expandable material expands, and a return spring, interposed axially between the casing and the body so as to retract the piston away from the body when the thermally expandable material contracts.

There are provided a throttle mechanism and the like that are capable of easily changing a cross-sectional area of a flow path according to an operating state. The throttle mechanism in an embodiment is a throttle mechanism that controls a flow rate of a fluid flowing through a flow path, and is configured to make a cross-sectional area of the flow path change autonomously according to temperature.

A thermostatic valve includes a hollow body, two openings opening into the body and being hydraulically connected by a pass section, and a shut-off component arranged partially in the pass section and having a thermostatic actuator, a return component, a valve capable of opening the first opening when actuated by the thermostatic actuator and of closing the first opening when returned by the return component. The thermostatic actuator includes a cylinder containing an expansion material and a stem defining an axial direction. A relative movement between the cylinder and the stem along the axial direction occurs under the action of the expansion material. The stem bears at an ends against an abutment element, which is movable under the action of movement component in the direction of the cylinder to allow the opening of the first opening when the temperature of the expansion material is below the threshold temperature.

A device that includes a thermostatic element, with a piston and a body movable along an axis with respect to one another under the effect of the expansion of a thermodilatable material, and a stopper moved axially by the body with respect to a fixed seat so as to open and close a fluid circulation passage. The stopper includes a flexible seal which rests sealingly against the fixed seat in order to close the passage, and a rigid frame which fixedly supports the seal. The frame includes a central portion, mounted around the body to be driven by the body, and a peripheral part, folded towards the axis, partially crushing the seal. The seal is held in place on the frame by being pushed, radially to the axis, directly against the body of the thermostatic element under the effect of crushing the seal by the peripheral portion of the frame.

A temperature-controlling water valve is provided. An adjusting assembly is assembled within the water valve and includes an adjusting member, a first elastic member, a blocking member and an abutting member. The first elastic member biases the abutting member, and the blocking member is fixed to the adjusting member to block the abutting member from detaching from a receiving hole of the adjusting member. A temperature-controlling assembly includes a valve member and a second elastic member biasing the valve member. Thermal expansion or contraction of a rod member of the valve member drives the valve member to move so that an overlapping area of the valve member and a first passageway of the water valve and an overlapping area of the valve member and a second passageway of the water valve change.

The invention concerns a thermostatic valve (1) comprising a closed hollow body (2), a first opening leading into the hollow body (2), referred to as the inlet opening (4), a second opening leading into the hollow body (2), referred to as the main outlet (5), a third opening, substantially perpendicular to the second opening, leading into the hollow body (2), referred to as the bypass outlet (7), and a seal (11) allowing the inlet opening (4) to be alternately separated from the main outlet (5) or the bypass outlet (7). The seal (11) comprises a thermostatic actuator (12) and a skirt (13) which is made of plastic material and has at least one window (19) suitable for being traversed by a fluid, the skirt (13) being capable of sliding in the hollow body (2), along an axis that substantially coincides with the axis of the thermostatic actuator (12), between a first position in which the skirt (13) seals the main outlet (5), such that the fluid flows between the inlet opening (4) and the bypass outlet (7), and a second position in which the skirt (13) leaves the main outlet (5) open and seals the bypass outlet (7), such that the fluid from the inlet opening (4) can pass through the window (19) and flow through the main outlet (5).

A thermostatic integrated faucet includes a valve assembly having an upper valve body and a lower valve body defining a mixing chamber therein, the mixing chamber configured to receive hot water through a hot water inlet and cold water through a cold water inlet. The thermostatic integrated faucet further includes a diaphragm assembly fluidly coupled to the mixing chamber, a sensor operatively coupled to the diaphragm assembly, a thermostatic unit disposed within the mixing chamber of the valve assembly, and a cam shaft coupled to the thermostatic unit. The thermostatic unit is configured to control a water temperature within the valve assembly and the cam shaft configured to control a range of the water temperature within the valve assembly. In various embodiments, the thermostatic unit includes a wax actuator configured to engage with the cam shaft and a mixing shuttle coupled to the wax actuator.

A water flow rate automatic control module, relating to the field of thermostatic shower fittings. The water flow rate automatic control module comprising a base, a valve body, a thermosensitive assembly, a diaphragm, wherein a temperature sensing part senses the temperature of passing cold water in real time; when the temperature of cold water is too low, the mixed water flow rate is slowed down, and more hot water is supplied to a thermostatic valve core assembly for mixing; when the temperature of cold water is too high, the mixed water flow rate is increased, and more cold water is supplied to the thermostatic valve core assembly for mixing. Therefore, the mixed water temperature range of the thermostatic valve core assembly can be ensured, and the problem of temperature adjustment failure or beyond the temperature difference caused by matching the thermostatic shower with a gas water heater is solved.
