Definitions

  • the invention relates to a bypass valve for pumps and heating systems with a control element which has two different sized valve plates connected via a rod, the valve plates and the rod connecting them are movably mounted in the axial direction of the inlet and outlet connections and the valve plate of the bypass valve has the smaller diameter.
  • a bypass valve of this type is known (DE-OS 2504292), in which an annular valve seat is assigned to the larger valve disk of the control element. When the bypass is fully open, the larger valve disc lies against the ring-shaped valve seat. If the larger valve plate of the control element lifts up from the valve seat, flow vortices arise in the area of the valve seat, which act on the larger valve plate and represent disturbance variables that cannot be calculated.
  • the valve seat for the larger valve plate increases the flow resistance when the bypass is closed.
  • the object of the invention is to simplify the housing construction in terms of production technology in the case of such a bypass valve and to reduce the flow resistance when the bypass is closed.
  • annular flow cross-section is present in all valve positions between the outer edge of the larger plate of the control element and the housing wall and the housing interior is in the flow direction behind the inlet opening to the bypass into the area of the end position of the larger plate tapered when the bypass is fully open and the interior of the housing then widens into the area of the end position of the larger plate when the bypass is closed.
  • the valve housing 1 has three connections, which are identified by directional arrows, namely the inlet 2, the outlet 3 and the bypass 4.
  • the valve is equipped with a control element 5, which consists of a smaller valve plate 6 of the bypass valve, a valve plate 7 with a larger diameter than the valve plate 6 and a connecting rod 8.
  • the control element is movably mounted in the flow direction of the valve.
  • the mounting of the connecting rod 8 is not shown in the figures.
  • annular flow cross section which changes when the control element moves in the flow direction of the housing due to the selected inner contour of the housing and shown in FIGS. 1 and 2.
  • the interior of the housing tapers conically in the flow direction behind the inlet opening 9 to the bypass into the region of the end position of the larger plate 7 when the bypass is open. This position of the larger plate is shown in FIG. 2.
  • the conical taper of the housing interior is assigned the reference symbol D1.
  • the interior of the housing is designated D at the point of greatest taper. From this point, the housing widens conically in the direction of flow, up to the end position of the larger valve plate 7 when the bypass is closed. This position of the valve plate 7 is shown in FIG. 1.
  • the described conical expansion of the housing is assigned the reference symbol D2.
  • the interior of the housing tapers again conically from the end position of the valve plate 7 with the bypass closed to the outlet connection.
  • the valve plate 6 is assigned a closing spring 10 which engages on the underside of the valve plate and is supported on the other end on a surface of the bypass line. The valve plate 6 is pressed against the valve seat 11 by the spring 10 and held in this position.
  • valve housing 1 is traversed by the medium in a straight direction.
  • the spring 10 is dimensioned such that it closes the bypass in the rest position (FIG. 1), but has no influence on the control.
  • the outlet line is open, the force of the medium flowing through acts on the larger valve plate 7. The force is transferred to the valve plate 6 and keeps the bypass closed.
  • the quantity to be drawn is equal to the flow rate (see points A1 and A2). If the purchase quantity is reduced, the curve of the purchase quantity runs parallel to the pump characteristic up to point B1 or B2. From point B1 or B2, the quantity can be gradually reduced to the value zero (see point C1 or C2), while the bypass flow increases from point D1 or D2 to point E1 or E2. Any point between points B and C can be controlled and held for an unlimited time.
  • the position of points B and E on the pump characteristic curve is structurally determined by the size ratio of the valve plate 7 to the valve plate 6.
