  • Patent number: 6435207
    Abstract: A flow regulation control valve for regulating volume flows in pipelines including valve housing with a flow chamber, a control or shut-off member arranged in the flow chamber for setting a desired flow state through the valve, at least one sensor arranged in the vicinity of the flow chamber of the valve housing for sensing a characteristic value of the flow through the flow chamber, an electronic data store or memory for storing specific characteristic values of the housing of the flow regulation control valve, and an evaluation unit which is connected to the sensor and determines the volume flow from the values measured by the sensor with reference to the characteristic values of the valve stored in the data store.

  • Patent number: 5826856
    Abstract: The invention concerns a tap fitting in which the gap between the tap spindle and the spindle lead-in in the housing is sealed off by means of a bellows-type seal. The end of the seal nearest the housing is connected to a sleeve which is sealingly mounted in the housing.

  • Patent number: 5143350
    Abstract: A gate valve has a one-piece casing which contains a valve chamber. The casing is provided with a tubular stub on either side of the chamber, and the stubs serve to connect the valve to a pair of pipes. The chamber has a non-circular sealing surface which is inclined to the direction of flow. A valving element having a non-circular sealing surface complementary to the sealing surface of the chamber is insertable in the latter via a selected one of the stubs. Following insertion, the valving element is connected to a spindle. Both the valving element and the spindle are held against rotation, and movement of the valving element towards and away from the sealing surface of the chamber is achieved by a rotary nut which is threaded onto the spindle. The sealing surface of the valving element delimits a region having a maximum dimension greater than the maximum dimension of the selected stub as considered in planes normal to the flow direction.

  • Patent number: 4792119
    Abstract: A valve wherein the housing has an internal seat having a sealing face which surrounds a seat area that is inclined with reference to the axis of a stem for the valving element. The sealing face is tapered and forms part of a conical surface. In order to ensure that the valving element is pressed against the sealing face, the line of action of the force which is applied by the stem is eccentric to the axis of the conical surface.

  • Patent number: 4303249
    Abstract: A seal for closing a gap which is present between a tubular housing member and a plate-shaped closing member pivotally mounted within the housing member in the closing position of the closing member includes two resilient sealing lips which, even when unstressed, assume substantially symmetrical curved configurations; when the closing member assumes its closing position, the sealing lips, which have an effective width exceeding that of the gap and which are detachably mounted on the housing member, are stressed and press against the closing member to seal the gap against penetration of media therethrough in either direction. The sealing lips surround the closure in an annular manner and are made of a metallic material.

  • Patent number: 4117859
    Abstract: A valve with a tubular valve body having two axially deformable bellows disposed between two flanges and flanking an annular seat which is movable axially of the body to thereby change the effective cross-sectional area of an annular passage between its internal valve surface and the valving surface of a valve element which is secured to one of the flanges by several ribs and is spacedly surrounded by the body. The device or devices which serve to move the seat relative to the valve element are located outside of the body.
