Definitions

  • the shaft carries a lug fixed on it which extends into the passage and is pivotally connected with the flap near the center of the latter. Rocking oi the shaft about its axis causes the flap to be moved towards and away from its seating.
  • a linkage is provided. This linkage comprises two arms and two links. The arms are carried on the shaft and are nomially stationary during operation. The links are connected with the arms and the flap. The angular setting of the arms, and hence of the flap can be changed by means of an adjustable stop mounted on the casing.
  • the present invention relates to flap valves, and more par ticularly to such valves in which the flap is moved away from its seating for opening while remaining approximately parallel to itself for a short distance and is then swung into a position, inside the passage of the valve, in which it is approximately perpendicular to its closed position.
  • One object of the present invention is to provide a flap valve in which the manufacturing difficulties connected with production of the housing and the flap drive mechanism are substantially reduced and furthermore to make possible a precise setting of the pivot bearings of the links on the housing without difficulties.
  • a further object of the invention is to provide such a flap valve in which the flap can be made radially symmetrical, so that an even sealing action is guaranteed along its whole periphery in every application.
  • the present invention consists in a valve comprising a casing defining a passage for the flow of material, a valve seat attached to the casing, a flap extending across the passage for engaging the seat, an operating shaft mounted on the casing substantially outside the passage, a lug which extends from the shaft to the flap is fixed on the shaft and is pivotally connected with the flap near its center, relative rocking movement between the flap and the lug being arranged to take place about an axis parallel to the shaft, at least one link, link anchoring means, the link being pivotally connected with the flap and the anchoring means for causing the rocking movement of the flap in relation to the lug when the lug is turned by the shaft, characterized by the provision of at least one arm, constituting the anchoring means, mounted on the shafi, and
  • the arms which were previously joumalled eccentrically, to extend into the center of the arrangement and thus provide a more convenient connection with the flap.
  • the flap can be provided with the center piece with a projection for pivotal connection with the lug and with the levers respectively.
  • the central arrangement of the lug and the links on the flap makes possible a radially symmetrical construction of the flap and thus makes possible an even sealing action along the periphery of the flap.
  • FIG. I represents a section along the line II of FIG. 2.
  • FIG. 2 represents a section along the line IIII of FIG. 1.
  • reference numeral 1 denotes a housing or casing, which at its ends carries welded-on flanges 2, 3, which can be connected with pipes in a pipe line which is to be controlled by the flap valve.
  • the casing 1 there is a seating ring 4 in which a seating part 5 is mounted against which the flap 6 rests with its periphery when the valve is closed.
  • the flap is an integral construction which in its center part carries a hollow boss 7, on to which a cover plate 8 is screwed.
  • the cover plate carries an extension 9 for carrying the two bearings 10 and I] for the lug l2 and the links 13 and 14.
  • the lug 12 is made u of two parallel limbs in the embodiment shown, as can be seen more particularly from FIG. 1.
  • the extension 9, 9a is made up of two parallel limbs as is shown by FIG. 1. Between the two limbs of the extension 9, there is the ivot bearing 10 for the lug 12, while on the end of the limbs of the extension 9, 9a remote from the flap 6 there are pivot bearings II for the links 13 and I4. As can be seen from the section of FIG. 2 the housing 1 is provided on its top side with a shroud 15 in which two sleeves l6, I? are welded on to the casing l.
  • These two sleeves accommodate the operating shaft 18 which has a free end connected with a drive mechanism for swinging the shaft about its axis.
  • the sleeve 20 carries the two limbs of the lug 12 so that on rotation of the shaft 18 about its axis the sleeve 20 also rocked so that the lever or lug 12 can be swung with the flap 6 mounted on it.
  • the links 13 and 14 pivoted in the pivot bearings 11 are, in the embodiment shown, connected at their other ends with arms 22 and 23 which are fixed on sleeves 24, 25.
  • the sleeves are journalled on the shaft 18.
  • the sleeves 24, 25 can be turned in the sleeves l7 and 16 but their position in relation to the housing or casing, and therefore also the position of the arms 22 and 23 in relation to the casing is fixed by a stop 26, which is mounted in a sleeve 27 fixed on U18 casing.
  • the stop can be set by means of the setting screw 28 so that by suitable operation of the two setting screws 28 for the two arms 22 and 23 with their extensions engaging the stops can be aligned without difficulty together with their pins 29 and 30, which provide pivotal connections with the links 13 and 14.
  • the course of movement of the flap 6 is indicated in FIG. 2 which for this purpose shows the end position of the flap in broken lines.
  • a valve comprising a casing defining a passage for the flow of material, a valve seat attached to the casing, a flap extending across the passage for engaging the seat, an operating shaft mounted on the casing substantially outside the passage,
  • a lug which extends from the shah to the flap, is fixed on the shaft and is pivotally connected with the flap near its center. relative rocking movement between the flap and the lug being arranged to take place about an axis parallel to the shaft, at least one link, link anchoring means, the link being pivotally connected with the flap and the anchoring means for causing the rocking movement of the flap in relation to the lug when the lug is turned by the shaft.
  • the improvement which resides in the provision of at least one arm, constituting the anchoring means, mounted on the shaft, and means for checking rocking movements of the arm in relation to the casing about the axis of the shaft. the arm extending towards the center of the flap from the casing.
  • the movement checking means comprises an extension on the arm and a stop on the casing for abutment on the extension.
