摘要:
A normally open solenoid operated modular valve includes a solenoid body receiving a coil and pole piece. A polymeric material valve body portion is releasably connected to the solenoid body. An armature/valve member slidably disposed in both the solenoid body and the valve body portion has a male threaded end shank. A polymeric material thread-in poppet/valve member includes an internal threaded portion engaging the male threaded end shank to retain the thread-in poppet/valve member on the armature/valve member. A resilient material valve ring is retained on the thread-in poppet/valve member. A cylindrical tube portion receives an armature/valve member rod portion. A biasing member acts against the armature/valve member and thereby acts to normally bias the valve ring away from contact with a valve seat surface created in the valve body portion defining a modular valve valve normally open position.

A flow reversing valve comprises: a reversing valve main body 2 adapted to be capable of assuming a first circulatory state in which a first main valve part 10A is in a fully open state and a second main valve part 10B is in a fully closed state and a second circulatory state in which the first main valve part 10A is in a fully closed state and the second main valve part 10B is in a fully open state; and a flow regulating valve 3'adapted to regulate the pressures of the respective back pressure chambers 17A and 17B of the first main valve part 10A and the second main valve part 10B. The flow regulating valve 3 places the reversing valve main body 2 in the first circulatory state by gradually reducing the pressure of the back pressure chamber 17A of the first main valve part 10A, and in the second circulatory state by gradually reducing the pressure of the back pressure chamber 17B of the second main valve part 10B.
摘要:
A diverter valve comprises a valve body defining first (1), second (5) and third (9) inlets and first (3) and second (7) outlets. A passage is provided between the first inlet and the first outlet and first (11) and second (13) interconnected valve members are provided within the valve body, the valve members being jointly movable between first and second positions. In the first position, fluid is able to pass from the first inlet to the second outlet and from the third inlet to the first outlet, the passage between the first inlet and the first outlet being closed. In the second position, fluid is able to pass from the second inlet to the second outlet and along the passage from the first inlet to the first outlet.

Die Erfindung betrifft ein Ventil insbesondere Dreiwegeventil zum Steuern des Durchflusses einer Flüssigkeit insbesondere als Misch- oder Verteilerventil einer Heizungsanlage mit einem kolbenförmigen Ventilstellglied, das in axialer Richtung zwischen einer geschlossenen und einer geöffneten Stellung beweglich ist, um den Durchfluss zwischen einem ersten und einem zweiten Kanal zu sperren und zu öffnen, wobei in der geschlossenen Stellung das Ventilstellglied mit seiner Dichtfläche an einem Ventilsitz dichtend anliegt, wobei das Ventilstellglied einen inneren Durchlass aufweist, der bei geschlossenem Ventilstellglied die beiden Kanäle verbindet, wenn der Druck im Eingangskanal einen bestimmten Wert übersteigt.
摘要:
The invention relates to a single-unit faucet that comprises a tubular faucet body (2) and a thermostatic cartridge (3) defining a pre-assembled assembly provided inside the faucet body and including a hollow shell (4) made of a plastic material, in which is provided a thermostatic means (5) for adjusting the temperature of a cold-fluid and hot-fluid mixture. In order to firmly and simply secure the shell in the faucet body, a rigid part (6) is provided between them, and is capable of movement along a movement axis (Z-Z) transverse to the longitudinal axis (X-X) of the faucet body, while being kinematically connected to the shell both in the direction of the axis of the faucet body and in rotation about said axis. The rigid part includes a bore (63) centred on the movement axis and opening on a face (62B) of the rigid part oriented towards the faucet body, in order to interact by screwing with the threaded rod (71) of a screw (7) for moving the rigid part until a bearing portion of said face is pressed against the lower face (2A) of the faucet body when the screw is inserted from outside the faucet body into a transverse through hole (21) of the faucet body, which is smaller than the head (72) of the screw.

The invention relates to actuator unit (4), in particular to an actuator unit (4) for a valve means (3). The actuator unit (4) comprises at least two mechanical sensor units (10,11), which are acting on at least one common actuating unit (15,24).
摘要:
A three-way poppet valve that can restrict or eliminate backflow without the use of an external check valve. Unlike conventional three-way poppet valves wherein both inlets can be open to the outlet at the same time during movement of the poppet, the valve according to the present invention can be configured to close both inlets prior to opening one of the inlets to the outlet. The valve features a poppet valve assembly that is operable to prevent both inlets from being open to the outlet at the same time. The valve assembly also reduces the force needed to close the valve against at least one of the inlets thereby allowing the use of a smaller actuator. A unique seal including a valve seat that is configured to conform to a valve member under sufficient pressure.
