摘要:
A central heating radiator control valve comprising a valve housing with an inlet, a main outlet and a branch outlet, and a valve member slidably mounted in the housing for movement between two terminal positions in one of which flow of fluid from the inlet to the main outlet is a minimum and in the other of which flow of fluid from the inlet to the branch outlet is a minimum.

The present invention features a multizone conversion system for converting a single zone system into a multizone system. The multizone conversion system is designed to require minimal renovations and does not require extensive new wiring. Each room within the new multizone system has its own thermostat controls and each room can be set to its own specific temperature. The multizone conversion system does not require new piping to and from the boiler. Each thermostat is equipped with a temperature sensing device, temperature setting controls, an LCD monitor or display and an RF circuit that includes an RF transmitter and an RF receiver. Each heating element within the room is outfitted with an input device that contains an RF circuit, a switching valve and a battery compartment. The thermostat communicates wirelessly with the output device located in the room and control the flow of the heated water through the existing heating element or alternatively through a bypass pipe if heat is not required.

A four-way valve for heat exchangers and hot water heaters comprising a valve seating housing which includes a hot water inlet opening at one end and a hot water return opening at the other end thereof; a valve guide integrally formed with the housing and disposed about the hot water return opening; and a plurality of spaced-apart, adjacent apertures disposed in a radial arrangement in said housing between said openings thereof. A valve housing head is mounted on the valve seating housing and couples a plurality of heating supply and drain pipes thereto. A hot water pipe from the hot water heater is disposed within the valve guide in the hot water return opening of the valve seating housing to couple the valve to the heater. Valve seats are disposed in the housing and valve head, and are engaged by end members formed on the end of a valve body slidably disposed on the valve guide. A rotatable adjustment head is coupled to the valve body for controlling the flow of water through the valve.

The invention relates to a heat emitter unit for a hot water heating system. The heat emitter unit is characterized by a valve and a heat emitter unit being integrated in a manner so that the valve casing and the heat emitter pipe to which fins are attached are in axial alignment. The heat emitter pipe has a central tube arrangement which provides in parallel a central bypass and a surrounding valve controlled passage. Heat from hot water flowing through the surrounding valve controlled passage is transferred through the finned pipe to the fins.
摘要:
A thermostat-regulated radiator valve for a single or double conduit central heating system comprising a generally T-shaped valve housing including one pass-through conduit and one perpendicularly branched-off conduit. The valve housing is mounted underneath a radiator with one end of the pass-through conduit in fluid communication with the radiator. An annular washer is coaxially mounted in the pass-through conduit at the junction between the pass-through conduit and the branched-off conduit and is substantially aligned with the axis of the branched-off conduit. A flexible hose or tube is sealingly mounted in the opening of the washer and extends through the part of the pass-through conduit attached to the radiator. A U-shaped bimetal element is mounted in the valve housing and has its legs extending on each side of the flexible tube so as to press around the tube at increasing temperature and thereby diminish the flow through the radiator.

A radiator valve has a housing with a displaceable valve stem in a passage, one end of which has a valve seat controlled by a valve member on the stem and the other end of which is controlled by a throttle element on the stem and which passage is connected between its ends with an inlet connection for hot water supply for dividing the inlet flow of hot water in one stream passing past the valve member to a feed outlet connected to the radiator inlet, and one stream passing past the throttle element to a return chamber and to an outlet pipe connection while bypassing the radiator, the return chamber being connected with a return inlet from the radiator.
