Definitions

  • This invention relates to a damper device comprising a flow conducting casing and a damper element turnably arranged in the casing, which element is mounted on a detachable clean-out door.
  • the damper device is preferably intended for air flow regulation in ventilation arrangements.
  • the known embodiment is associated with the primary drawback that the mechanics for the transmission of forces to the damper element for the regulation of the latter gets somewhat complicated.
  • a secondary drawback with the known embodiment is that it becomes difficult to arrange measuring terminals for air flow regulation in the clean-out door depending on that the damper element in the form of a • blade has to move in relation to the clean-out door.
  • a known damper device is the so called throttle damper. These are often marketed with three different types of damper elements in the form of blades, namely sealing, non-sealing and perforated damper blades. From a stocking point of view, this damper device becomes very space de- manding, especially for manufacturing companies, which forms a tertiary drawback.
  • the present invention intends to indicate a damper de ⁇ vice with such a constructive design that the primary drawback discussed above is eliminated or at least reduced.
  • this object is obtained through the clean-out door being turnably arranged in relation to the casing and the damper element being connected to the clean-out door to accompany the turning of the latter.
  • the secondary drawback above is reduced thanks to measuring terminals being arranged in the clean-out door for static measurement of fall of pressure.
  • Fig 1 is a schematic side view of the damper device in open position
  • Fig 2 is a view of the damper device, regarded according to the line A in Fig 1 ,
  • Fig 3 is a view of the damper device, regarded from the line B in Fig 1 ,
  • Fig 4 is a side view of the clean-out door of the damper device, regarded from the line C in Fig 2,
  • Fig 5 is a perspective view of a non-sealing, blade like damper element
  • Fig 6 is a perspective view of a sealing, blade like damper element.
  • the damper device comprises a flow conduct- ing casing 1.
  • this casing has a curved mantle wall, for in ⁇ stance a cross-section-wise circular one, though this is not necessary.
  • the casing 1 is intended to be part of a flow conducting channel, for ex ⁇ ample a ventilation arrangement, and is intended to be connected to fur ⁇ ther casing or channel elements at its ends 12, 13, sealing elements 14 arranged at these ends being intended to function sealingly.
  • a damper element 2 is turnably arranged in the casing 1 .
  • This is mounted on a detach ⁇ able clean-out door 3. More precisely, the clean-out door 3 is turnably ar- ranged in relation to the casing 1 and the damper element 2 is connected to the clean-out door to accompany the turning of the latter.
  • the damper element 2 has a blade like shape and at the bottom it shows a curved portion 15 designed in correspondence with the inner, curved mantle wall of the casing 1.
  • the clean-out door 3 seals an opening 16, through which admission into the casing 1 can be obtained at depiaced clean-out door.
  • the orifice 16 is defined by a tube portion 17, which adjoins to the casing 1 and preferably extends at an angle, especially almost right angle, to the longitudinal centre axis of the casing 1.
  • the casing 1 merges into the tube portion 17 via curved transition portions 18 appearing from Fig 1.
  • the damper element 2 will extend a bit up into the tube portion 17 and presents opposite edges 19, which are essentially mutu ⁇ ally parallel.
  • the clean-out door 3 presents a body portion 20 which is introducible into the tube portion 17 and which, for example, might con ⁇ sist of a plate casing filled with a fire resistant, and suitably also thermally insulating, material, such as mineral wool.
  • the clean-out door 3 comprises a mantle 21 designed to externally engage around the tube portion 17 so that the outer end of the latter becomes located be- tween the mantle portion 21 and the body portion 20.
  • a sealing means 22 can be mounted to seal between the mantle portion 21 and the tube portion 17.
  • the damper element 2 is detachably connected to the clean-out door 3. More exactly, the latter presents members 4 for displaceable engage ⁇ ment with the damper element 2.
  • the engagement members 4 consist of slots, into which the damper element runs. Accordingly, different types of damper elements can be mounted on one and the same clean-out door 3 by being displaced into engagement with the slots 4 of the clean-out door.
  • the described damper device can also be used during channel cleaning thanks to the damper element being taken away from the clean-out door before the clean-out door is reassembled during the course of cleaning. Extra sealing doors for cleaning are therefore not required.
  • Fig 5 an example of a simple, non-sealing, blade like damper element is shown. This has been reinforced thanks to a centrally located folding 16.
  • the damper element presents portions 23 for engagement in the en ⁇ gagement members 4 of the clean-out door 3.
  • the por- tions 23 have the character of flaps protruding towards the sides and be ⁇ ing insertable in the member 4 designed as slots.
  • Fig 6 an example of a sealing damper element is shown, where two single damper blades 17 have an interjacent, sealing packing 18.
  • the portions 23 for en ⁇ gagement with the members or slots 4 of the clean-out door consist of parts of the damper blades 17 bent towards opposite sides.
  • the damper device comprises members for restoration of an adjusted flow value after channel cleaning.
  • This member suitably comprises a rider 15, which is connected to the clean-out door.
  • This rider can be fixed at the tube portion 17, for example by means of a locking screw protruding through the rider and the tube portion 17.
  • the measuring terminals 6 and 7 emerge into the bottom side of the clean-out door 3 at 8 and 9 respectively, on either side of the damper element 2, as most clearly appears from Fig 2.
  • Each of the measuring terminals 6 and 7 comprises an upper tube portion 24 and a tube 25, which is connected to the tube portion 24 and which extends through the clean-out door 3 and ends with an end portion 26 a bit beneath the bottom side of the clean-out door.
  • a transverse means 27 is fastened, which is in ⁇ tended to facilitate the turning of the clean-out door by being gripped by the hands of a present operator.
  • this transverse means 27 has the shape of a hollow, cross-section-wise rectangular profile, which upwards shows a recess 28. In this recess 28 a part 29 that includes the tube portions 24 of the measuring terminals 6, 7 is insertable.
  • a cover 30 serves for sealing of the upper ends of the tube portions 24 when no measuring of fall of pressure is accomplished.
  • This cover 30 might for example be pivotabiy connected to the part 29 and present suitable lock ⁇ ing members to be fixed in relation to the part 29 when being in its closed position sealing the tube portions 24. The closed position is shown in Fig
  • the measuring terminals 6, 7 could also be designed as rigid tube sec ⁇ tions extending through the clean-out door 3 beside possible manoeuv ⁇ ring means arranged on the latter.
  • At least one means 10, 11 for increase of fall of pressure is mounted in the area between the orifices 8, 9 of the measuring terminals 6, 7 on the bottom side of the clean-out door 3.
  • This means 10, 11 for increase of fall of pressure is designed as a plate.
  • I I extend as appears from Fig 2 and 3 from the damper element 2 to the outer edge of the clean-out door 3.
  • the purpose of the one or more means 10, 11 for increase of fall of pres ⁇ sure is to, at completely or almost completely open damper element 2, work promotively for fall of pressure between the orifices 8, 9 of the measuring terminals 6, 7 on the bottom side of the clean-out door so that a fall of pressure can be measured and the flow amount thereby be set ⁇ tled.
  • the described damper device is not just limited to the above described embodiment.
  • the essence of the idea of the in ⁇ vention is that the clean-out door 3 shall be turnable in relation to the casing 1 , and the damper element 2 so connected to the clean-out door that the turning of the latter gives rise to readjustment of the damper element in the casing 1 and thereby change of the throttling of the damper element of the flow through the casing.
  • a multitude of modifications can be made.
