Definitions

  • the object of the invention is a damper for gases, which includes a duct section formed of a frame with sealing edges and inside it a hatch part that rotates on an axle and a rotation device for rotating the axle, and with it the hatch part, tightly against the sealing edges of the frame, and in which the axle is taken through the frame.
  • Dampers referred to in the introduction are known from, among other sources, Finnish utility models numbers 1671 and 2289, as well as Finnish Patent Application 954454. Means are well known from these for sealing the frame and edges of the hatch part quite well against each other. If necessary, two shutoff edges are used in tandem, in addition, shutoff air can be pumped between them, when it is possible to effectively isolate detrimental gas.
  • axle point forms only a small part of the hatch, when the rest of the damper is very well sealed, it forms a significant place for leaks.
  • This invention is intended to create a new kind of axle-sealing construction, by means of which the problem of sealing the axle can be solved simply and reliably.
  • the characteristic features of the invention are described in the accompanying Patent Claims.
  • a flexible sleeve used as an axle seal according to the invention permits tolerance-free constructions. It should be noted, that the axle need not be sealed over the entire circumference, it is sufficient when the pressurized side is sealed as a separate compartment.
  • Frame 1 of the version of the shutoff damper shown here is divided into three compartments, in each of which there is a hatch part 4. These are secured to the frame part by means of axle 11 and they can be rotated with the aid of a conventional mechanism. Sealing devices, which correspond to the counter-surfaces in the frame, are set in the edges of hatch part 4. If desired, sealing constructions equipped with two sealing edges can be used. The sealed penetration of the frame by the axle is marked with the reference number 5.
  • Cylindrical component 7 includes nibs 7.1 at the outer end, which remain under the flange of collar 6. Collar 6 can be attached by the flange to frame 1, with the aid of screws 12, which also secure the flexible cylindrical component 7. Collar 6 may be of the type BRM 10 TFF.
  • the flexible cylindrical component is advantageously manufactured from spring steel, when the cut blank for it is as in Figure 3. At its ends, narrow flanges 7.2 are bent from the blank, with nibs 7.1, which are bent to an angle of 90°, bent at the other edge.
  • blank 7' is bent into a cylinder, with flanges 7.2 opposite each other, these fitting into the axial break in collar 6.
  • the break in the bearing collar may have to be slightly enlarged.
  • a sealing construction according to the invention can be dismantled and assembled from outside, as can clearly be seen from Figure 2. After removing screw 12, collar 6 and with it cylindrical component 7 can be pulled out along the axle. Bearing this kind of installation in mind, a small cut can be machined in the front edge of counter collar 8.
