Self louvred grille
(57) Abstract:The invention relates to natural ventilation of buildings. Changing the differential pressure before and after the grating 1 is perceived to be mutually bound by the bellows 5 and 7, respectively installed in the room behind the bars 1 in the exhaust duct. The resulting movement of the rod 8 of the bellows 7 through the rods 13 and 14 is transmitted blinds 2, turning them accordingly changing pressure drop. The technical result is lower costs of thermal energy by the permanence of the natural flow of the exhaust when changing gravitational pressure. 1 Il. The invention relates to the field of natural ventilation of buildings.Natural exhaust channels of buildings is calculated to allow the required flow of air under gravitational pressure corresponding to the ambient temperature +5oC. With decreasing outdoor temperature during the cold period of the year increases gravitational pressure, increased consumption of natural extracts, which leads to the additional cost of heating the infiltrating air.Known automatic flow regulator in the CSO is the design complexity. Also known self-adjusting blinds (ed. mon. 504912, CL F 24 F 13/08, Bulletin of inventions No. 8), which disadvantage is that their design takes up a lot of space in the duct.The prototype of the invention is a ventilation grate, comprising a housing, defined therein blinds, managed wings (Handbook of the designer. H 2. Ventilation and air conditioning, Ed. I., Staroverova, ed. 2nd, Rev. and ext. M, stroiizdat, 1977).The disadvantage of this ventilation grills is that it does not provide a reliable flow control natural extracts at varying gravitational pressure.The invention is aimed at reducing the cost of thermal energy by the permanence of the natural flow of the exhaust when changing gravitational pressure.The result is achieved that the self-regulating louver grid, comprising a housing defined therein movable louvers, managed wings, to the housing secures the bracket to which is attached a bellows with a barbell, on sinocom the end of which is fastened a second bellows with the rod; the rod and the rod is placed in guides attached to the casing d is pivotally connected with the second thrust, the node connecting them placed in the guide groove on the plate attached to the housing; the other end of the second pull hinged to the wings.The drawing shows a diagram of the device.Self louvred grille consists of a casing 1, defined therein the deflector 2, connected to a common connecting rod 3. On the housing bracket 4 is fixed to the bellows 5 to 6 bar, sinocom the end of which is fixed to the bellows 7 and rod 8. The grille fixed rails 9 and 10, in which is placed the rod and the rod. Stem clamp 11 is fixed clutch 12, to which is pivotally attached to the first rod 13, the second end of which is pivotally connected with the second thrust 14. The node connecting them placed in the guide groove 15 cut in the plate 16 attached to the housing. The other end of the second pull hinged to the connecting rod 3.Self-adjusting grid works as follows. Originally blinds 2 grilles are installed in the position that provides the calculated air at a design pressure drop before and after the grating. When appropriate this state, the position of the rods 13 and 14 are fixed by the position of the coupling 12 on the rod 8, with clamp 1 which correspond only to the change of the differential pressure before and after the grating and is not associated with changes in atmospheric pressure. With increasing differential pressure before and after the grating, on which react bellows 5 and 7, the rod with the clutch moves to the left, pulls the rod 13, which in turn pulls the rod 14, and the pivot joint is placed in the groove settlement form 13. The other end of the second pull 14 moves the connecting rod so that the rotation 2 took place at the desired angle - this condition corresponds to the shape of the groove 13. When reducing the pressure drop everything happens in the opposite direction.Thus, self-regulating louvred grille provides a constant flow of natural extracts with varying gravitational pressure, which leads to saving of heat in the cold season. Self louvred grille, comprising a housing defined therein movable louvers, managed wings, characterized in that the housing secures the bracket to which is attached a bellows with a barbell, on sinocom the end of which is fixed a second bellows with the rod, the rod and the rod is placed in guides attached to the grille on the rod there is mounted a coupling with lock, to which the hinge is attached to the first rod, the other end of the first traction pivotally connected with the second thrust, the site of their Saint with wings.
