Definitions

  • Cattle shed ventilation system with air intake valves, and such valves for such systems.
  • the present invention concerns a cattle shed ventilation system with air intake valves, and also such valves for such systems. It is widespread practice that use is hereby made of wall-mounted intake valves configured in a box-like manner as rectangular ducts with a pivotable damper which from an outer lower-edge area ex- tends at an angle upwards and inwards for closing against an upper seating-edge area at the inner end of the box or the rectangular duct.
  • the damper is spring-loaded to swing upwards towards this closed position, and thus in a simple manner can be disposed for controlled opening merely by being connected with a draw-string, by means of which it can be drawn down to provide a smaller or larger opening .
  • the air intake is established by creating a certain underpressure in the cattle shed by means of roof -mounted extraction fans which can work with requirement-controlled effect, and whereby it is relevant to regulate the intake valves in order to achieve the desired admission characteristic of the sucked-in air. It is herewith of importance that the system works with angularly-disposed, pivotable dampers, in that with a slight degree of opening these will have an upwardly-controlling influence on the intake air, which is advantageous for a good distribution of air in the cattle shed when operating with a low air exchange in connection with cold external air.
  • the one point of action corresponds to an ordinary course of regulation between fully closed and fully open position, it can thus be achieved with the use of the second point of action that the opening is de- layed, because the string is now slack with a certain over-length, so that the opening is not initiated until the string is tightened, but still completed simultaneously with the opening of the "ordinary" valves.
  • a desired differentiation can hereby be achieved merely by a changeover between the points of action, and furthermore without any need to change the fastening of the string on the drawbar.
  • fig. 1 is a perspective view of the inside of an intake valve according to the invention
  • fig. 2 is a more detailed view of a string fastening part thereof
  • fig. 3 shows a side section thereof.
  • a wall- mounted air intake valve consisting of a rectangular duct 2 in which is disposed a damper 4 which, from an upwardly-sloping closed position, is pivotable downwards around a lower hinge connection 6 by the pulling down a string 8, said string being connected to a fastening ele- ment 10 on the damper 4 and via a fixed reversing roller 12 to an horizontally-extending drawbar 14 which extends from a not-shown drive station.
  • This can have, for example, computer-controlled means for the displacement of the drawbar 14 and herewith generally for the opening and closing movements of the damper 4 depending on variations which arise in the detected ventilation requirements.
  • a movable string holder in the form of a re- taining ring 10 which is provided on an arm part 16 extending radially from a rotatable disk 18 which has an element 20 for manual control, fig. 2.
  • the disk 18 has an associated rear-disk 22 by means of which the disk 18 can be rotatably mounted in a round hole 24 in the damper 4, so that the disk is rotatable with a suitable degree of friction.
  • the object is to enable the eye 10 to be brought into the two positions, as shown in fig. 3, i.e.
  • Fig. 4 shows a preferred modification of the system for turning, cf. figs. 2 and 3.
  • the adjusting knob 20 is provided on the inner side of the damper 4 inside the housing 2, while on the outside there are provided eye elements 10 which are individually retained in a rotatable manner by means of an eccentrically-disposed bolt 24, which also holds the two parts 18 and 22 together.

Abstract

Les systèmes de ventilation à clapets destinés aux abris pour le bétail utilisent souvent des clapets (2) comportant des volets (4) placés en angle, qui peuvent être réglés pour s'ouvrir ou se fermer graduellement par un mouvement pivotant autour d'un bord inférieur. On sait par ailleurs qu'il est avantageux de pouvoir régler le rapport d'accouplement entre le cordon et ces volets pivotants. La présente invention permet de résoudre ce problème d'une manière particulièrement simple: les volets pivotants individuels sont équipés de moyens de fixation (10) pour un cordon, qui sont soit disposés à au moins deux hauteurs différentes sur le volet ou sont réglables entre de telles positions, p. ex. par simple rotation d'un bouton de réglage (18).
