Definitions

  • the invention relates to a quick-closing valve for arrangement at intake and blow-out openings of ventilation systems, in particular fast-moving railway vehicles, consisting of a frame with at least one through-flow slot, which is provided with an adjustable closing element, which can be brought from an air pressure-dependent adjustment drive to the through-flow slot in the closed and open positions is.
  • Pressure wave valves of the type mentioned and known at the outset are designed in the form of slot valves. They consist of two outer plates with opposite openings and a movable middle plate, also with slots that are moved by mechanical movement so that the slots no longer match.
  • the adjustment drive must retract the middle plate and / or a return spring must be provided in addition to the plate.
  • a quick-closing device for air outlet openings of shelters, a quick-closing device is known according to CH-A-427 514, with which external pressure or suction waves are intercepted.
  • the at least one air passage slot is delimited by two frames, which are arranged with respect to one between them strip-shaped closing part have concave seating surfaces for the closing part, which rests against the one pair of seating surfaces during a pressure wave and against the other pair of seating surfaces during a suction wave and thereby closes the air passage slot.
  • This is, so to speak, a flutter valve which, for this reason alone, is not suitable for the present purpose, quite apart from the fact that it cannot be opened and closed in a targeted or controlled manner.
  • the invention is based on the object of designing and improving such a valve in such a way that the opening and closing movements of the closing element can take place practically without friction and that the closing element automatically moves into its open position after the closing load has been eliminated defers.
  • a quick-closing valve in that the edges which laterally delimit the at least one throughflow slot are convexly curved with respect to the inflow direction and behind these edges the closing element is designed and arranged in the form of a likewise convex but weakly curved spring leaf which its length corresponds at least to the length of the convexly curved edges of the throughflow slot and is held on the frame with one end and is displaceably guided on the frame with its other end region.
  • the control pulse for actuating the actuator which can be a small pneumatic cylinder or an electromagnetic drive as before, is also supplied as before by a pressure wave sensor, which can be a so-called pressure wave fan, for example, and which, as is known, does not require any further explanation here.
  • the convexly curved edges are designed as edges of webs arranged in the frame, the webs forming flank legs of M-profiles arranged in the frame. This is not only favorable for the outflow, but also takes into account that such quick-closing valves generally have a plurality of through-flow slots next to one another.
  • an adjusting element which extends transversely to the spring leaf and which is at the top in the open position at the top is fixedly arranged on the frame and is operatively connected to the spring leaf and is coupled to the actuator by its other free end.
  • the quick-closing valve according to the invention is explained in more detail below with reference to the drawing of an exemplary embodiment which has a plurality of throughflow slots next to one another.
  • the quick-closing valve basically consists of a frame 1 with at least one through-flow slot 2, which is provided with an adjustable closing element 3, which can be brought from an air pressure-dependent adjustment drive 4 to the through-flow slot 2 in the closed and open positions. It is essential for such a quick-release valve that the edges 5 which laterally delimit the at least one through-flow slot 2 (several are shown) and which form the valve seats for the respective spring leaf 3 'are convexly curved with respect to the inflow direction and the closing element 3 behind these edges 5 is designed and arranged in the form of a likewise convex but weakly curved spring leaf 3 ', which corresponds in length L at least to the length of the convexly curved edges 5 of the throughflow slot 2 and is held at one end 6 on the frame 1 and with its other end region 7 on Frame 1 is guided.
  • the end region 7 of the spring leaf 3 ' which is displaceably guided on the frame 1 is connected to the Adjustment drive 4 connected, in the illustrated embodiment such that a frame 10 extending transversely to this in the region of the spring leaf 3 'projecting in the open position has an end 11 which is operatively connected to the spring leaf 3' and with its other free end 11 is coupled to the actuator 4.
  • the actuator 4 Apart from the fact that such a design could be provided for each existing spring leaf 3 ', it is also possible to detect all spring leaves 3' with the actuating element 10 and to link only one adjusting drive 4 to the actuating element 10, as shown in FIG. 2 .
  • this configuration results in a spatially advantageous assignment of the adjustment drive (s) 4, as shown, vertically and in the flow shadow behind the spring leaf (s) 3 '.
  • the convexly curved edges 5 are designed as edges of webs 8 arranged in the frame, which form flank legs 8 ′ of M-profiles 9 arranged in the frame. Two adjacent M-profiles 9 thus each delimit a throughflow slot 2 with their flank legs 8 '. As can be seen from the flow arrows in particular in FIG. 1, this results in favorable and largely swirl-free conditions for the outflowing air when the valve is open.
  • 2 flow guide elements 13 are arranged in front of the throughflow slots, which are also fastened to the frame 1 in a suitable manner. These flow guide elements 13 can also be designed as snow-repellent air grilles.
  • one end 6 of the spring leaf 3 ' is firmly bound in the frame 1 by, for example, folding.
  • the weakly convex shape of the spring leaves 3 ' is important insofar as the direction of adjustment against the edges 5 is thus ensured under load.
  • flat spring leaves would also be possible, but additional measures would have to be taken to ensure that such spring leaves could only bend towards the edges 5 and be able to rest against them.
