A room temperature control system (1) is shown having at least two radiators (2, 3, 4) located in the same room each radiator (2, 3, 4) being provided with a valve (7, 8, 9) for controlling a flow of heat carrying fluid through the respective radiator (2, 3, 4), each valve (7, 8, 9) being actuated by an electronic control unit (10, 11, 12) and the control system having at least one temperature sensor. Such a system should have a good comfort. To this end the control units (10, 11, 12) are part of a communication system (13, 14, 15) in which the control units (10, 11, 12) communicate with each other to share information and the control units (10, 11, 12) control the valves (7, 8, 9) according to the shared information.

A user interface for a thermostat that controls a radiator valve can include a user input member that is movable from a home position to a set point increase or decrease position to increase or decrease a set point temperature of the thermostat. In some embodiments, a return mechanism returns the user input member to the home position after being released from one of the set point increase and decrease positions. In some embodiments, the user interface can include an indicator panel and controller that controls the indicator panel to provide an indication of when the set point temperature of the thermostat is being adjusted. In some embodiments, the user interface can also include a lockout controller that prevents further set point temperature adjustments using the user interface when the set point temperature differs from the environmental temperature by a specified amount.

Regulator device for a choke element (15) that can be inserted in a connection pipe (12) of at least two plates (11a, 11b) of a heat exchanger (24), wherein the device is suitable to regulate the sizes of a flow passage aperture (26) defined by at least one membrane (16) of the choke element (15), the membrane (16) having, or not, a transit slot (17), and a possible hole (23). The device comprises a handle (20) and at least one arm (19) associated to the handle (20) and provided, at one of its ends, with a regulator tooth (21; 21a, 21b, 21c, 121) extending angled with respect to the longitudinal extension of the arm (19).
摘要:
A self-adjusting balance valve controller (401) controls water flow through a hydronic emitter (101) in a heating and/or cooling temperature control system. The valve controller (401) obtains a measured temperature differential between an inlet (102) and an outlet (103) of the hydronic emitter and determines a displacement of a coupling pin (303) from the measured temperature differential. The valve controller (401) then instructs a driving mechanism (304) to move, through a coupling mechanism (306), the coupling pin (303) to adjust a valve (106) that results in a desired water flow through the hydronic emitter (101). The valve controller (401) may maintain a stable temperature differential at a desired differential value, which may be obtained through a user interface (404) or from a memory device (405). Moreover, the desired differential value may vary with different times of operation or temperature control situations.
摘要:
Bei einer Vorrichtung zum Heizen von Räumen, umfassend zumindest eine zentrale Wärmequelle und umfassend den Räumen zugeordnete Heizkreise, die über zumindest eine zentrale Versorgungsleitung für erwärmtes Heizmedium mit der Heizquelle leitend verbunden sind, ist vorgesehen, dass in der zentralen Versorgungsleitung und in jedem Heizkreis jeweils ein Heizmedium-Volumenstrommesser angeordnet ist. Mit einer Vorrichtung dieser Art ist eine bessere Verteilung der vorhandenen Wärmeenergie auf einzelne Heizkreise möglich.
摘要:
A valve, in particular a heat exchanger valve (1) is provided comprising a valve housing (2) and a valve top (3) inserted into an opening in said valve housing. Such a heat exchanger valve should be produced with low costs. To this end said valve top (3) is made of plastic material.
摘要:
The invention relates to a valve arrangement (1) comprising a valve housing (2), a valve inlet (3), a valve outlet (4), a main valve element (5) and a main valve seat (6), the main valve seat (6) being arranged in a flow path between the valve inlet (3) and the valve outlet (4) and the main valve element (5) cooperating with the main valve seat (6), the valve housing (2) containing an insert (7), the insert (7) comprising a gasket element (8) so as to provide a fluid seal. According to the invention, the gasket element (8) comprises a gasket section being arranged slanted with respect to a direction of the axial extension of the insert (7). Furthermore, the invention relates to the insert (7) for the valve arrangement (1). The invention allows to provide a valve arrangement (1) at a low cost since machining effort on the valve housing (2) may be reduced.
摘要:
A valve arrangement (1) is disclosed comprising a heat exchanger valve (2) and an actuator (3), said valve (2) comprising a housing (4) and a valve element (11), said actuator (3) being fixed to said housing (4), acting on said valve element (11), and comprising a rotary handle (16), wherein a set-point of said valve arrangement (1) is adjustable by a rotation of said handle (16) in a predetermined angular area. Such a valve arrangement should facilitate servicing of a heat exchanger connected to such a valve arrangement. To this end said handle (16) is rotatable beyond a border of said angular range, wherein said valve (2) is completely shut-off upon a rotation beyond said border.
