Definitions

  • the invention relates to a shut-off valve for shelter ventilation ducts according to the preamble of claim 1.
  • the air supply line is surrounded by two coaxial channels, which are connected to one another at their ends opposite the valve closure body.
  • the shock front of a pressure wave strikes the valve closure member directly here, while the mass-bearing pressure wave forces an extended path from the end of the air supply line to the valve passage to ensure that the shock front has brought the valve body into its closed position before the pressure wave passes through the air duct through the Channels has reached the valve passage.
  • a closure valve is also known, in which a single channel is provided, which begins at the mouth of a pressure line leading to the valve closure plate, and in which a screw-shaped wall extends the path of the air duct to the valve passage (DE-B 1 153 259) .
  • centrifugal dust separators with a plurality of centrifugal dust separators in which the individual centrifugal separators are arranged next to one another in a housing and the dust discharge cones of the centrifugal separators open into a common dust collecting chamber, which at its lowest point extends across a slot-shaped slot-shaped chamber that extends across the width of the dust collecting chamber Opening is connected to a dust extraction chamber and a dust extraction nozzle with which the centrifugal dust separator can be connected to a suction fan (DE-B 1 507 842).
  • the object of the invention is to provide a combination consisting of a pressure surge protection device with an air duct designed as a deflection and extension of the path and a mechanical dust filter which can be implemented in a compact design.
  • the function of the path deflection and extension which is required to increase the running time of the incident shock front or mass-affected pressure wave, is given by the mechanical filter designed as a centrifugal separator through the swirl paths functionally required in the separator rooms (cyclones) for dust separation and to the immersion tube 180 ° deflection reached.
  • Swirl channels, 180 ° deflection and immersion tube thus fulfill two functions. They effect the dust separation by centrifugal force and deflection and serve to extend the running time of the shock front of the pressure wave up to the valve passage, so that it is longer than the closing time of the valve closing body.
  • the closure valve 2 shown in Fig. 1 has an annular air housing 4, which is provided at one end with a lid-shaped outlet housing 6 with an outlet port 8. At the other end of the housing 4, a lid-shaped air inlet housing 10 is provided, which is provided with an inlet connector 12. This housing 10 is connected via an intermediate flange 14 to the housing 4, in which a residual gas outlet channel 16 is formed.
  • an intermediate wall 18 is arranged, which is provided in the middle in the direction of the outlet port 8 with a cylindrical collar 20 which, together with a cylinder ring 22, forms a U-shaped annular channel 24 in which a valve closure body 26 is guided with a cylindrical projection 27.
  • the valve closure body is axially movable and is held in the open position shown by essentially radial tension springs 28 with slight pretension.
  • the associated valve seat 30 is formed on the outlet port 8 of the outlet housing 6.
  • a valve closure body 36 of a suction protection device is arranged, which in turn is held in the open position by tension springs 38, in which it rests against stop ribs 40, which are formed on the intermediate flange 14.
  • the valve closure body 36 cooperates with a valve seat 42 at the inner end of the inlet connector 12.
  • a plurality of radial ribs 13 and 9 are provided in the form of a star in the inlet connection 12 and in the outlet connection 8, respectively, as stops for the valve closure members 36 and 26, respectively.
  • a central air supply duct 44 is formed, which here is provided at its downstream end with an air guide profile 46, which is followed by a radial extension 48, which together with the intermediate wall 18 forms a radially inwardly open annular duct as an air supply chamber for the cyclones to be described below.
  • two inner circles 50 of a plurality of cyclones of a multicyclone are formed on two partial circles A and B. These housing contours are cast into the wall of the fuselage housing with axes parallel to the housing axis.
  • Air outlet tubes 52 engage in these cyclone housings integrally formed in the fuselage housing 4, around which outside in the housing inlet in the usual manner Swirl body 54 are provided. With their opposite end, the outlet pipes 52 of the individual cyclones are sealingly guided through the intermediate wall 18. They open into an annular channel 56 which merges into the valve passage 29.
  • the dust discharge end 58 of the cyclone housing 50 ends in the radial end wall 60 of the housing 4, which closes the annular channel 16 open to the housing 4 in the intermediate flange 14.
  • the ring channel 16 is provided with an outlet nozzle 62 through which the dust-laden residual air exits, which exits the cyclones into the ring channel 16.
  • An air-conveying fan can be arranged on the suction or pressure side of the valve. If necessary, a suction fan can be connected to the outlet 62.
  • untreated air passes through the intake port 34 and, if provided, on the outside of the valve closure member 36 of the suction protection device into the air duct 44 and from here radially into the annular duct 48, from which it flows with the opposite direction of flow via the swirl body 54 in a more uniform manner Distribution occurs in the individual cyclones, from which in the vortex core clean air is discharged via the air outlet pipes 52, which then exits through the valve passage of the pressure surge valve and the outlet port 8.
  • the cross section of the air duct 44 is to be selected as a function of the air throughput of all cyclones.
  • a pure multicyclone can also be produced with the same components from which the valve described above is formed.
  • the valve closure body 26 is omitted, and a continuous partition wall 18 is then provided, in front of which the air supply line 44 then ends.
  • the valve closure member 36 of the suction valve is also omitted here.
  • a closure valve with an annular housing 70 is again provided, to which a multicyclone 72 is connected on one side, preferably being cast on directly.
  • the cyclone housings 74 are cast in rows in this multicyclone.
  • the cyclone housings of adjacent rows are preferably offset by half a pitch T / 2, so that the cyclone housings of adjacent rows are each nested in order to be able to accommodate the largest possible number of cyclone housings in a given volume.
  • An air transfer duct 75 is again arranged above the multicyclone 72, into which the air passes laterally from the air duct 78 in accordance with the flow thread 76 shown.
  • the partition wall 84 between the clean air collection chamber 80 with the air outlet connection 82 and the valve passage 81 on the one hand and the housing 70 on the other hand extends to the cyclone housing of the multicyclone 72.
  • the residual air collecting duct 92 into which the residual air outlet openings of the cyclones open, is formed here on the air inlet housing 94, which carries the inlet port 96.
  • the residual air collecting duct 92 is provided with an outlet connection 98.
  • a multicyclone arranged laterally on the fuselage housing 74 of the closure valve can have a width perpendicular to the view in the drawing, which can correspond to the diameter of the annular housing 70.
  • the cyclones of the multicyclone can also extend as circular ring sections over a limited part of the circumference of the housing 70.
  • the shut-off valve with the attached multi-cyclone can be adapted to the respective installation conditions.
  • the cyclone housings are integrally molded into a housing.
  • the cyclones with separate housings, for example made of injection-molded plastic housings, in appropriately prepared chambers of the valve.
