Definitions

  • the invention relates to a switching valve for the transmission of fluids, in particular for filling gas tanks.
  • a switching valve in the design of a quick-connect coupling, wherein a housing having a fluid inlet and a fluid outlet and a plurality of valves are provided to ensure a secure seal.
  • These valves are switched after applying the quick-connect coupling by turning a control lever in a certain predetermined order, first the exhaust valve is opened, then with further movement of the control lever, the collets are closed and finally the inlet valve is opened.
  • the control lever is in this case via an eccentric shaft with the sliding sleeve for the application of the collets and with a sealing piston in engagement, which also releases the fluid inlet after the connection of the plug-in coupling.
  • a vent valve is provided which allows the pressure equalization before removing the plug-in coupling, so that there is no risk of recoil even at high pressures.
  • the outlet valve acts like a check valve.
  • Another switching valve is off GB-A-1 521 639 known, which is to be regarded as the closest prior art.
  • the invention has for its object to provide a switching valve of the type mentioned, which enables easy handling with a compact design and prevents contamination or fluid reflux by targeted venting.
  • the proposed switching valve with slide is particularly suitable for use in the filling of industrial gas tanks, resulting in a simple and compact design, since the switching valve with attached control valve for pressure-controlled actuation of a pivot lever is designed concise concise and stable and thus integrated to save space in filling can be.
  • the pivot lever provided in this case is preferably designed with a translation, i. with different lever lengths, so that a powerful operation of the valve actuation valve is achieved.
  • the piston of the control valve is preferably connected via a bolt with the pivot lever, which is mounted in particular on a pivot axis in an intermediate housing. This results in a sensitive control, in particular when the piston surface cross sections of the piston are formed on the inlet / outlet side the same.
  • this construction achieves a simple connection to the valve housing, as well as a compact connection with a bypass line for controlling the pressure-controlled control valve.
  • a switching valve 10 In Fig. 1 and 2 an embodiment of a switching valve 10 is shown.
  • the switching valve 10 has a tubular housing 11 with a plurality of housing parts 11a, 11b and 11c screwed together, the right housing part 11c acting as inlet area 12 and the left area as outlet area 13 for the forwarding of the fluid to be transferred.
  • the inlet region 12 has an adapter 14, to which a fluid line 12 'for supplying the fluid to be transferred is connected.
  • the connection adapter 14 can be configured correspondingly in adaptation to the fluid volume to be transferred, in particular to the respective desired passage cross-sections.
  • a corresponding adapter 14 'for the discharge line 13' In the outlet region 13, a corresponding adapter 14 'for the discharge line 13' is provided.
  • a bypass line 15 is interposed, which thus acts on a mounted on the housing 11 control valve 20 with the inlet pressure and the outlet pressure, as explained below.
  • a check valve 25 is arranged, which in the in Fig. 2 illustrated closed position under spring pressure against a valve seat 26 seals to prevent backflow from the outlet 13.
  • a slide valve 27 which can be moved axially along the central axis and move a movement here to the right a sealing washer 24 of a vent valve 35.
  • the vent valve 35 and the slide switch 27 are in this case actuated by pivoting a pivot lever 50, since this is coupled to the slide switch 27, here for example by positive engagement via an annular groove 29th
  • an inlet valve 45 with an associated valve seat is furthermore arranged toward the inlet region 12.
  • the inlet valve 45 is also axially displaceable by the pivot lever 50 and by the coupling with the slide valve 27, since the slide valve 27 on the rightward movement of the sealing disc 24 of the vent valve 35 in the manner of a sequence control and a valve spool 47 of the inlet valve 45 from the Shown here closing position shifts into the open position, so that the inflowing from the inlet portion 12 fluid through the hollow valve spool 47 and a passage in the sealing washer 24 and the tubular slide valve 27 can flow to the outlet 13, since in this case also the check valve 25 by the filling pressure ( from the refueling system or other pressure source / Beglallpumpe) is pressed into the open position.
  • control valve 20 is mounted on the housing 11 (with inlet valve 45, venting valve 35 and check valve 25 inserted therein) via an intermediate housing 19.
  • a piston 21 (circumferentially sealed) is used, which is acted upon by a spring 22 and thus pressed into the right position shown here.
  • the two end faces, which are exposed to the respective pressure in the bypass line 15, are preferably dimensioned equal, so that the piston 21 can move sensitively with the slightest pressure differences between right (inlet) and left (outlet) side.
  • the threshold pressure is determined by the spring 22.
  • the piston 21 is also coupled by a bolt 53 with the pivot lever 50 so that the control valve 20 pressure-controlled via the slide 27, the valves 35 and 45 can operate.
  • the sealing disc 24 and the slide valve 27 and valve slide 47 separate slightly in the axial direction, so that the pressure can degrade to a pressure compensation chamber 44, which is formed as a paragraph-like annular space in a gradation on the housing part 11c around the sealing washer 24 around.
  • the lever lengths are different on both sides of the pivot axis 52, eg here in the ratio 3: 1, so that a power transmission is achieved.
  • a powerful actuation of the slide 27 and the valves coupled thereto can be achieved, even with a relatively small construction of the control valve 20 (or diameter of the piston 21).
  • This translation can be relatively easily changed eg by replacing the intermediate housing 19 and the pivot axis 52 mounted therein or extension of the pivot lever 50, for example in adaptation to the respective filling pressures.
  • the switching valve 10 with attached control valve 20 can be used variably, especially the conversion, if necessary, by means of screws 60 (see. Fig. 1 ) can be carried out quickly.
  • the bypass line 15 can also be connected to the adapters 14, 14 'or directly to the respective inlet / outlet region 12, 13, of the housing 11, in order to improve the compactness of the pressure-controlled valve.
