Definitions

  • the invention relates to a regulating valve, which can be fastened in an executed with an internal thread bore of a hydraulic door closer, with a base body, followed by a Regulier Scheme, and a thread with anti-rotation, wherein the thread is screwed with the anti-rotation in the internal thread of the bore ,
  • a regulating valve for a door closer which consists of a base body and a Regulier Scheme.
  • the Regulier Scheme this case is designed like a sleeve and connected via a ball joint connection with the body.
  • the Regulier Schemees arranged on the Regulier Scheme rotation is provided, which is designed as a projection or projection. This approach is longitudinally movably guided in a groove within the housing of the door closer.
  • Other generic regulating valves are off EP 2 134 914 and DE 202007004104 known.
  • the invention provides that the rotation has a plastic layer on the thread flanks of the regulating valve, which cooperates with the internal thread of the door closer. As a result, a clamping effect is achieved which avoids unintentional loosening or twisting of the regulating valve.
  • the base body has a thread, on whose thread flanks a plastic layer is arranged.
  • the thread shape is predetermined on the base body, which is equipped by a method with the plastic layer.
  • the thread is arranged on the shaft of the main body. As a result, the production of the thread can be realized in a simple manner.
  • the Regulier Council consists of a shaft extension with one end, wherein the shaft extension is connected via a material guide with the plastic layer in the thread flanks of the thread on the regulating valve.
  • the regulation area can be made in a single operation.
  • the base body has a blind hole on which the head area is arranged opposite the longitudinal axis of the base body.
  • the regulation region can be produced in one piece in a positive and positive fit and in alignment with the main body.
  • the blind bore has an angular or non-circular cross-section. This results in the insertion of the regulating valve in the bore of the door closer to an additional safeguard against rotation.
  • the approach has at least one pin which projects into a bore of the body.
  • the plastic layer is positively and / or non-positively and / or cohesively arranged on the thread.
  • the clamping effect can be very finely adjusted because it engages directly in the corresponding thread and there in the thread flanks of the door closer.
  • a high surface pressure between the thread flanks of the internal thread and the regulating valve is generated.
  • the interlocking threaded parts no longer rotate independently by such an arrangement.
  • a manual and / or intentional adjustment of the regulating valve is of course still possible.
  • the regulating valve can be regulated at any time in accordance with the desired requirements with respect to a defined closing behavior, the rotation preventing an independent rotation, in particular by occurring dynamic loads, effectively prevented.
  • the Regulier Council has an end which faces away from the base body and is tapered, preferably cone-shaped. This embodiment provides a more accurate adjustment of the oil flow, which significantly affects the closing speed of the closing process. Despite the acting forces, starting from the flowing fluid to the regulating valve, the plastic layer on the thread flanks of the regulating valve ensures that the regulating valve does not unintentionally and independently regulate itself at the thread.
  • the regulation region is arranged on the main body by an injection molding process.
  • the Regulier Scheme is made on simple operation.
  • the main body can be made of a metal, for example zinc, brass or steel, wherein the Regulier Scheme preferably consists of a plastic material.
  • the said plastic may be fiber-reinforced, in particular
  • the plastic may have a certain proportion of glass fibers and / or carbon fibers and / or aramid fibers.
  • the base body and / or the Regulier Scheme consist of a plastic material, in particular the main body consists of a fiber-reinforced plastic.
  • the complete regulating valve is produced in a single operation.
  • the door closer has an inlet channel, an outlet channel and a conical valve seat, wherein a fluid can be conducted through the inlet channel along the valve seat to the outlet channel.
  • the free end of the Regulier Schemees is substantially adapted to the valve seat of the door closer.
  • FIG. 1 shows a regulating valve 1, which is provided for a hydraulic door closer. This may be various door closers, for example, with a cam eccentric according to DE 103 61 085 A1 or with a rack according to DE 199 01 234 C1 betreibbarsind.
  • the regulating valve 1 has a receptacle 7 for a sealing element. This sealing element can, for. B. be an O-ring.
  • the shaft 2a of the regulating valve 1 has a thread 2, wherein in the thread flanks a plastic layer is present.
  • the material outlet opening 6 and the material guide 5 is attached. Further points FIG. 1 a section plane XX.
  • FIG. 2 shows a full section of the regulating valve 1 along the sectional plane XX of the FIG. 1 ,
  • the regulating valve 1 consists of the main body 3 and a regulating region 4.
  • the regulating region 4 consists essentially of a shaft extension 4c and a projection 4a. Furthermore, pins 4b are shown, which forms the plastic layer on the thread 2 through the material guide 5.
  • FIG. 3 shows a regulating valve 1 from FIG. 1 in perspective view.
  • a head portion 8 is mounted, which is used for the fitter to operate the regulating valve 1 with the appropriate tool.
  • the thread 2 is in FIG. 3 for the sake of simplicity, shown schematically.
  • the free end 11 of the Regulier Schemees 4 is cone-shaped, running tapered.
  • FIG. 4 shows the main body 3 in a perspective view.
  • the thread 2 is shown schematically for the sake of simplicity.
  • the main body 3 has a blind hole 9.
  • the blind hole 9 can z. B. have a rectangular, square or triangular cross-section.
  • material outlet openings 6 and 6a are shown, which protrude continuously into the positive blind hole 9.
  • FIG. 5 shows a door closer 20 in which a regulating valve 1 is screwed.
  • the thread 2 which has the plastic layer, corresponds to the internal thread 25 of the door closer 20.
  • a sealing element 21 is present on the regulating valve 1.
  • the free end 11 of the Regulier Schemees 4 and thus of the regulating valve 1 is located in a conical valve seat 24 of the door closer 20.
  • an inlet channel 22 through which an oil is passed.
  • the free conical end 11 of the Regulier Schemees 4 is not directly on the valve seat 24, so that the oil can flow through the between the valve seat 24 and the free tapered end 11 of the Regulier Schemees 4 forming narrow channel in the direction of a drain channel 23.
  • the flow cross section for the oil can be adjusted, whereby in particular the closing behavior of the door closer 20 can be influenced.
  • the acting on the regulating valve 1 by the flowing oil forces can cause no unwanted rotation of the regulating valve 1 due to the described rotation even in the tolerance range.
  • the regulating valve 1 described above is manufactured in the following manner.
  • the main body 3 is in advance in the form according to FIG. 4 made, that this has a thread 2 on its shaft.
  • the base body 3 is inserted into operating means, preferably an injection molding tool.
  • the regulating region 4 is formed by the injection molding tool.
  • the plastic layer is formed on the thread 2 through the material outlet openings 6 and 6a and the material guide 5.
  • the injection process becomes a plastic material used, which is a polyacetal (POM) in the present embodiment, which is characterized among other things by its good sliding property, good chemical resistance and high abrasion resistance.
  • POM polyacetal
  • the plastic layer on the thread flanks a clamping effect between the thread 2 of the regulating valve 1 and the internal thread 25 of the door closer 20 is achieved, since the clearance between the threads is filled. As a result, a high surface pressure of the interlocking threaded parts is achieved.
  • the regulating valve 1 can be rotated manually at any time and / or unscrewed from the bore of the door closer 20.
