摘要:
According to one embodiment of the invention, a system for regulating a temperature of a fluid through a conduit comprises a conduit, a moveable obstruction, an actuator, and a pressure generator. The conduit has an inlet, an outlet, and an opening between the inlet and the outlet. The inlet is operable to receive fluid into the conduit and the outlet is operable to dispense of fluid out of the conduit. The moveable obstruction is operable to at least partially cover the opening and thereby resist flow of fluid through the opening. The actuator has a chamber with a heat sensitive substance. The heat sensitive substance is operable to change a characteristic upon receipt of thermal energy from fluid traveling through the conduit. The actuator is additionally operable to move the obstruction upon the change in characteristic of the heat sensitive substance. The pressure generator is operable to apply pressure to the chamber to change a property of the heat sensitive substance. The change in property of the heat sensitive substance changes the movement of the obstruction by the actuator.

摘要:
The description relates to a device for the regulation of the amount of a medium in a heating or cooling system, comprising a combined valve, which in one and the same valve housing includes one part for pressure difference regulation (2) and one part for flow limitation (3), the flow being limited in a stepless, adjustable way, i.e. the device obtaining an adjustable Kvs-value. Also, the chosen Kvs-value can be limited by a plunger, which always can operate with its complete stroke length.
摘要:
A device for a flow regulation and a measurement of a medium in a heating or cooling system, which device comprises a multifunctional valve, which comprises a collector (1) with measuring outlets and an adapter for discharge and which is mounted jointly with a flow control part (2), the one part being rotatable in relation to the other part but locked in an axial direction.

摘要:
A combined control and regulating valve (1) having a housing (2) with an inlet (3) and an outlet (4) as well as a partition (5) between said inlet and outlet and having a seat (6) designed for an interaction with a main valve body (7), which is adjustable from outside. To said inlet and said outlet are connected a measuring nipple each (50 and 74, respectively) via a bore (30, 31 and 40, 41 respectively) for the measurement and the control of temperature and/or pressure. One of the measuring nipples is designed as a multiple function nipple (50) having a cut-off-valve permitting tapping and filling of the medium, which is to be controlled/regulated. In order to enhance reliability in operation, to provide even more precise and reliable measuring results, to reduce the risk of clogging of the cavities leading to the measuring nipples, to reduce costs for manufacturing and/or fitting, to provide preconditions for various conditions of operation and for partial changes as well as for being able to affect other valve properties, like sealing properties and use of differently designed or dimensioned valve bodies, at least one bore (30, 31) is extended axially to communicate with a so extended portion (110) with a zone of the medium channel (73) downstream of said seat (6) via an area immediately above said valve body (7) or around said seat (6) by means of a casing provided with a groove.

A combined control and regulating valve (1) having a housing (2) with an inlet (3) and an outlet (4) as well as a partition (5) between said inlet and outlet and having a seat (6) designed for an interaction with a main valve body (7), which is adjustable from outside. Said inlet and said outlet are connected to one measuring nipple each (31-39 and 41-49 respectively) for the measurement and the control of temperature and/or pressure. One of the measuring nipples (41-49) is designed as a multiple function nipple (50) having a cutt-off-function designed to interact with a seat (53) in a passage (40), which receives said nipple. In a housing neck (55), which encloses said nipple, are access openings (56) disposed, through which e.g. water can be discharged or filled, when said nipple is in its outer screwing position. Said neck is enclosed by a completely closed casing (57) or a casing (57') having a connection (60), which casing is retained by means of a nut (66) screwable on said neck, said nut having an opening (67), through which the outer end of said measuring nipple projects, at which end the nipple is provided with an inner insertion and control opening (38) as well as a cover (37), which covers said opening.
