Flow regulator for regulating the gas supply to a burner of a gas-heated device

The innovation relates to a flow regulator for regulating the gas supply to a burner of a gas-heated device, its The controller housing consists of a lower part connected to the gas supply and an upper part with a burner connection piece, in which a Re ^ eI sleeve provided with several openings is inserted, on which a float with .iegelfiansch controlling the gas passage through the openings arranged and at the open end of the with gases:. ; openings provided bottom of a cylindrical sleeve surrounding the regulating sleeve and the float, forming an annular gap with the regulating flange Regulator cup is attached, the end of which is open towards the burner connection piece via one of the gas inlet openings surrounding and concentrically surrounding the regulator cup with adjustable cross-section with the gas supply in Connection is, wherein for changing the cross section of the passage formed on the upper part of the housing gas passage openings Gas passage openings on an adjusting disk

are assigned, which can be rotated by an adjusting screw that is accessible from the outside and rotatably mounted in a housing extension is.

Volume regulators of the type mentioned are already known. The known Flow regulators are relatively complex both in construction and in assembly, since apart from the cone bowl there is an adjusting disk is provided with gas passage openings. The adjusting disk is used to change the cross-section of the passage the gas passage openings on the upper part of the housing and can be rotated by means of an externally accessible adjusting screw, which in a bent driving tab 3n of the adjusting disk intervenes.

The innovation is based on the task of building and lj to simplify assembly.

The object is achieved according to the innovation in a quantity regulator of the type mentioned at the outset in that one at the upper end of the regulator cup, the radially protruding annular disk edge is also provided with the gas passage openings, which are located on after the burner connection piece through channels formed towards the end of the upper part are assigned, and that the passage cross-section can be adjusted by turning the regulator cup.

In a preferred embodiment, it is preferred that on the circumference the edge of the ring disc has a tooth gap-like recess and at the inner end, the tangential to the edge of the ring disc Adjusting screw a tooth-like annular bead is arranged, which engages in the recess on the annular disc edge.

The gas flow regulator according to the innovation is under construction and assembly simple, since it has fewer individual parts than the known designs. The controller bowl is also available

provided with an annular disk edge, which gas passage openings has, so that just by turning the regulator cup by means of the adjusting screw, the cross-section of the passage of the Gas passage channels on the upper part of the housing can be changed.

The subject of the innovation is explained in more detail using an exemplary embodiment shown schematically in the drawing.

Show it:

Pig. 1 shows a cross section through a newly designed one Volume regulator along the line I - I in Figure 2,

FIG. 2 shows a vertical central section along the line II-II in FIG. 1.

The device shown in the drawing for regulating the gas supply to a burner has a regulator housing which consists of a lower part 10 and an upper part 11. The lower part 10 is connected to the gas supply and can be part of a gas fitting, not shown in full, of which only the gas safety valve with its valve seat 12, closing element 13 and closing spring H assigned to it is visible. A flange edge 101 or 111 is provided both on the lower part 10 and on the upper part 11, which are braced together with the interposition of a seal 15 when the housing parts are assembled. The upper part 11 ends in a burner connection piece 112, into which the end of a regulating sleeve 16, which is provided with several openings 17, is inserted. When installed, the regulating sleeve 16 is secured in its axial position in the burner connection piece by means of the closing spring 14, which is located on the one hand on the closing member 13 of the gas safety valve and on the other hand on a transverse wall 18 of the regulating sleeve

supports. This can be done from the gas supply side through the openings 17 from, so from the lower part 10 coming gas pass into the interior of the regulating sleeve 16 and over the burner connection piece 112 flow to the burner, not shown. On the Regeihüise 16 a window 19 slides, which the gas passage controls through the openings 17 in a known manner and which with a cone-shaped control flange 191 is provided. The regulating sleeve 16 ur.a the float I9 with the Control flange 191 are in a known manner from one Surrounding a piece of existing regulator cup 20, the bottom? 01 of which is attached to the free end of the regulating sleeve 16 and whose cylindrical wall 202 between itself and the edge of the control flange 191 of the float 19 forms an annular gap. On the ground 201 of the regulator cup 20 are also known per se Gas inlet openings 21 are provided. Through the gas inlet openings 21 gas flows into the interior of the regulator cup 20, to which it flows through the between the regulating flange 191 and the can flow through the cylindrical wall of the regulator cup 20 through the annular gap again. The annular gap forms there in known way a throttle point, which between the space below and the space above the control flange 19Ί of the Float 19 creates a pressure difference which determines the position of the float influenced. D "s after the burner connection piece 112 zu 'ffene end of the regulator cup 20 protrudes in a known manner a passage surrounding the gas inlet openings 21 and concentrically surrounding the regulator cup 20 with an adjustable passage Cross-section with the gas supply on the lower part 10 of the device) in connection, wherein for changing the cross-section of the passage Gas passage openings 22 formed on the upper part 11 of the housing, gas passage openings 23 on an adjusting disk are assigned, which are accessible through an from the outside in a Housing extension 113 rotatably mounted adjusting screw 24 is rotatable.

According to the innovation, a radially protruding annular disk edge 25 is provided at the upper, open end of the regulator cup 20, which at the same time as the gas passage: -,.; . Tongues 23 is provided, which through channels 114 ⁷ ^ It the C ".." In this way, the ring disk edge 25 is formed at the same time as the adjusting disk. The adjustment of the passage cross-section is carried out by turning the regulator cup 20, the annular disk edge 25 of which with the gas passage openings 23 acts like a diaphragm opposite the passage channels 114 in the upper part 11. The regulator cup 20 is rotated by means of the adjusting screw 24, which runs tangentially to the circumference of the annular disk edge 25 and is formed with a tooth-like annular bead 241 at the inner end. A tooth gap-like recess 251, into which the tooth-like annular bead 2 <1 of the adjusting screw 24 engages, is arranged on the circumference of the annular disk edge 25. By turning the adjusting screw 24 in one sense or the other, the same is screwed into or out of the projection 113 of the upper part 11, the regulator cup 20 being rotated in one sense or the other. Due to the interaction of the gas passage openings 23 of the annular disk rim 25 with the gas passage openings 22 of the passage channels 114 in the upper part 11, the cross section of the gas passage can be adjusted.

The device according to the innovation can be made up of a few Assemble easily manufacturable items and is easy to assemble.
