Definitions

  • the invention relates to a regulating valve with an adjusting screw and an associated valve sleeve for a door closer or hydraulic swing door drive.
  • regulating valves are generally known and are used for a wide variety of purposes.
  • the regulating valve is screwed with its adjusting screw into an adjusting thread and the valve sleeve is guided in a guide area.
  • misalignments can repeatedly occur between the center axis of the adjustment thread and the center axis of the guide area. This leads to problems with valve actuation. It can also happen that the valve sleeve rotates when the valve is actuated, which changes the throttle cross section.
  • a regulating valve which is used in a door closer can be found in US 1,770,250.
  • This valve is manufactured as a one-piece part, ie valve body and adjusting screw are one.
  • a groove is made on the elongated stem.
  • the valve body and adjusting screw are separated from one another.
  • the German utility model G 92 03 872 discloses a door closer with a fluid throttle valve, which ensures thermostatic throttling in the event of fluctuating temperatures. To achieve a set closing speed of the damping medium, even in the event of changes in temperature, this is achieved by providing an area on the valve seat which has a curved course.
  • the wall of the flow channel can also be designed accordingly. This measure is intended to ensure that the throttle gap does not change linearly with corresponding temperature fluctuations.
  • No. 4,148,111 shows a throttle valve for a door closer, which consists of two parts.
  • the valve stem is conical and is pressed into the valve body, which has an external thread and is adjustable, by means of a cylindrical extension.
  • the connection of a valve cone to a head of a valve spindle is taken from DE 1 958 503.
  • the valve cone is held on the valve spindle by means of a bore running transversely to the longitudinal axis and pinning to be inserted therein.
  • the regulating valve according to the invention has the advantage that it is due to a snap connection between an adjusting screw and a valve. tilhülse allows mobility between the adjusting screw and the valve sleeve, so that misalignments can be easily compensated. In addition, a snap connection is easily detachable, so that different operating conditions can be taken into account by simply replacing the valve sleeve.
  • the snap connection is designed as a ball joint connection.
  • a ball-and-socket joint ensures, with a simple construction, good and all-round mobility of the valve sleeve with respect to the adjusting screw, so that misalignments can be easily and easily compensated for.
  • valve sleeve consists of plastic, in particular of an electrically conductive material.
  • valve sleeve In order to prevent twisting of the valve sleeve and thus to maintain the basic shape of the throttle cross section, the valve sleeve is provided with an anti-twist device according to a preferred development.
  • the anti-rotation device can advantageously be designed as an extension which is guided in a longitudinally movable manner in a groove in the valve housing.
  • the anti-rotation device can also be formed by an eccentric offset of the central axis of the adjusting screw to the central axis of the valve sleeve. Both design variants represent an effective anti-rotation device in a simple manner, in which the basic shape of the throttle cross section can be maintained under any conditions.
  • valve sleeve can be designed as a valve pin. This enables a simple and quick adjustment of the regulating valve to a wide variety of requirements, since the The valve sleeve or the valve pin can simply be plugged onto the adjusting screw via the snap connection.
  • valve sleeves with different flow cross-sections eg. B. in the form of a triangle, a circle or a rectangle
  • the valve sleeves with different flow cross-sections are interchangeably attached to the adjusting screw.
  • a requirement namely a low sensitivity of the throttle cross-section to clogging due to contamination of the flow medium, can be met.
  • Contamination occurs particularly with small flow cross-sections and thus decisively change the flow rate of the valve.
  • a flow cross-section must therefore be sought which has a low tendency to blockages and at the same time the basic shape is not changed by the adjustment of the cross-section.
  • valve pins with different cone angles and / or different valve pin lengths can be attached to the adjusting screw.
  • Different valve pin lengths can be used to react to the different viscosity behavior of different oils so that a so-called thermoconstant valve can be implemented, even if a different oil is to be used with the same regulating valve.
  • an adaptation to the viscosity behavior of the respective oil can take place.
  • Adaptation to different valve pin lengths is particularly simple if, according to a preferred embodiment, identical or different intermediate links are provided which are plugged together until the required valve pin length is reached.
  • the intermediate links are preferably connected to one another via a snap connection, in particular a ball joint connection. dung. This not only ensures a simple and quick connection of the intermediate links to one another, but also takes into account possible misalignments between the central axis of the adjusting screw and the central axis of the guide area for the valve sleeve or the valve pin.
  • an insert in particular in the form of a filter or a magnet, is arranged in the valve sleeve. This makes it possible to generally bind impurities or metallic particles in order to prevent the throttle cross-section from becoming clogged.
  • a triangle and preferably an equilateral triangle is used as the throttle cross section.
  • Such a cross-section while maintaining the basic shape of the throttle cross-section during the adjustment of the valve, has a low sensitivity to clogging by impurities and a progressive change in the throttle cross-section takes place depending on the adjustment parameters.
  • the shape of the triangular cross section also plays a crucial role.
  • the isosceles triangle represents the optimal cross-sectional shape compared to all other triangular cross-sections.
  • a constant basic shape of the throttle cross-section can advantageously be achieved in that an outflow or inlet bore connected to the regulating valve is laterally offset from the valve sleeve bore.
  • valve sleeve has a small wall thickness with an expanding throttle cross section.

  • the throttle cross section in the valve sleeve 2 is designed as a triangle and preferably as an equilateral triangle.

This results in a low temperature dependence of the throttle resistance.
