Definitions

  • the invention relates to a ventilation valve having a body and a front plate connected thereto, the body comprising a truss provided with an opening to which a hollow spindle that extends in the axial direction of the opening in the truss and coaxially with it is attached, the front plate comprises a pin which is connected to the front plate in an orthogonal direction the pin of the front plate is inserted into the hollow spindle, whereby a flexible member is fixed to the pin of the front plate, the widest point of the flexible member is larger than the inner diameter of the hollow spindle such that the flexible member compresses and directs a spring force on the inner surface of the hollow spindle when the pin is inserted in the hollow spindle.
  • the ventilation valve may be an incoming air valve or outgoing air valve fixed to a wall or ceiling of a room space.
  • incoming air is taken through the incoming air valve, and correspondingly air from the room space exits through the outgoing air valve.
  • a room space may refer to any indoor space in which ventilation is arranged. Incoming air is typically taken from outdoors and outgoing air is removed outdoors.
  • This invention concerns valves that consist of a valve body, fixed to an opening in a wall or ceiling, and a front plate.
  • the valve body has a truss, in the middle of which an opening is traditionally made with an internal thread, to which a pin fixed to a front plate and having an external thread is screwed. Once the correct position of the front plate is achieved, the joint may be locked with a nut. To turn the screw, a tool is needed not only when installing it but also in case of a potential adjustment.
  • the Finnish patent application discloses 20175150 discloses a ventilation valve which has, fixed to the front plate of the valve, a pin which is pushed in a hollow spindle in a valve body.
  • the pin of the front plate has a curve made in it to increase friction between the pin and spindle parts.
  • a preferred embodiment of the ventilation valve according to the invention is characterized in that the flexible member is fixed to a free end of the pin.
  • a second preferred embodiment of the ventilation valve according to the invention is characterized in that the flexible member is fixed at least partly on the side or around the pin.
  • Yet another preferred embodiment of the invention is characterized in that the flexible member is substantially an oval-shaped loop made of metal wire.
  • Yet another preferred embodiment of the invention is characterized in that before insertion into the hollow spindle, the widest pat of the loop is larger than the inner diameter of the hollow spindle.
  • Figure 1 shows a front plate of the ventilation valve according to the invention.
  • Figure 2 is a cross section of the structure of the incoming air valve when the pin of the front plate is inserted in the hollow spindle.
  • the body 1 of the ventilation valve may be round, as in the drawings, or angular.
  • the ventilation valve may be an incoming air valve or outgoing air valve. In both cases, the body 1 may be alike.
  • the body 1 has a truss 2 with an opening 7. Fixed to the truss 2, by welding, for example, there is a hollow spindle 3 that extends in the axial direction of the opening 7 in the truss and coaxially with it.
  • the measurement system of airflow disclosed in the FI patent application 20175150 may also be implemented in this ventilation valve.
  • the pin 4 of the front plate 5, with the flexible member 6 in it, is inserted inside the hollow spindle 3 in the body 1.
  • the oval shape of the flexible member helps the insertion, because the tip of the flexible member is narrower than the centre part.
  • the flexible member 6 compresses and directs a spring force on the inner surface of the hollow spindle. This achieves good friction between the parts.
  • the front plate 5 is thus continuously adjustable in relation to the body 1.
