  • the extruded body has four elongated, separate chambers. However, there is also the possibility of providing more than four chambers. Some of the chambers are separated from one another by Z-shaped webs in which the valve seats of the on / off valves are formed.
  • the explanations below relate to FIG. 1.
  • the gas is led from an inlet opening on the right through a sieve 26 to the first chamber. From this chamber, the gas flows through the first on / off valve (shown here in the open position) into the next chamber, from which the gas flows through the second on / off valve 28 (shown here in the closed position) to a third chamber with a circular shape Cross section is performed.

  • the control disk 45 is held by means of a locking ring 38.
  • the magnet armature 40 connected to the rubber valve plate 39 is displaceable in a guide tube 41.
  • the upper end of the magnet armature 40 has a smaller diameter, so that the effect of the magnetic flux is improved.
  • One end of the guide tube 41 is connected to an immovable magnetic stop 29.

  • the rod 9 is guided in a cylindrical spacer 10 with a built-in flap function, on the right side of which a ring gear with an integrated stop is provided.
  • the spacer can be serrated spindle 1 3, Fig. 1, are rotated.
  • the rod 9, the rubber valve plate 8, the spacer 10 and the valve spring 11 are used during assembly as a unit, which is sealed with an O-ring.
  • the spring 14 presses the spacer 1 0 against the spindle 13 and at the same time provides for a necessary play compensation.
  • the spring 1 1 is connected to the rod 9 and acts as a closing spring of the main valve 8.
  • the control of the main valve 8 takes place via a second diaphragm control system, also shown in FIG. 2, which comprises a diaphragm 19 with a diaphragm plate 20.
  • the gas can flow through a channel 18 and a small nozzle 7 with a diameter of approximately 0.25 mm and from there through a channel to an actuator 53.
  • a bore 56 can also be seen, which is connected to a chamber downstream of the actuator 53.
  • a spring 22 which is connected to the actuator 53 creates a bias against the pressure of the membrane 19.
  • the gas flow from the nozzle 7 can thus be directed upwards, where it balances the force of the spring 22 and then by the downward Bore 56 escapes, which opens into a compensation chamber from which there is access to the chamber to the left of the membrane 1 6.
  • the gas flow to the nozzle 7 can also be directed via an orifice to the chamber to the right of the membrane 1 6.
  • the main valve 8 is thus in a certain equilibrium position, with any gas pressure fluctuations on the inlet side being automatically compensated at the same time. This balancing of the main valve 8 takes place with the aid of the control membrane 1 9. If the gas pressure changes with a certain value, the pressure on the outlet side can only vary within predetermined limits in this way.
  • the profile body is relatively long, see FIG. 3.
  • a number of nozzles 60 are provided in connection with the curved chamber which are subject to the regulated outlet pressure of the gas. In this way, there is the possibility of accommodating a plurality of nozzles 60 in one and the same valve construction, the nozzles 60 being able to be arranged at any distance, so that the gas can be metered to burner tubes attached next to it.
  • Fig. 4 shows a further pipe for ignition gas, the ignition gas being discharged after the first solenoid valve in this case.

Abstract

L'invention concerne un dispositif de commande et de régulation de l'alimentation en gaz comprimé menant à un brûleur à gaz pour chauffer de l'eau dans une chaudière. Ce dispositif comprend un canal pour le gaz comprimé et un régulateur commandé, muni d'une soupape de gaz dont la tête (8) est pressée à l'aide d'un ressort (11) contre un siège (12) de soupape. Les canaux et les sièges de soupapes de gaz de certaines soupapes d'arrêt sont formés dans un corps extrudé découpé en morceaux de longueur prédéterminée et pourvu de pièces terminales. Le corps extrudé comporte quatre chambres oblongues séparées les unes des autres, dont deux au moins ou davantage sont séparées les unes des autres à l'aide d'entretoises en forme de Z, qui font simultanément office de surfaces de siège des soupapes d'arrêt. On obtient ainsi une électrovanne pour gaz nettement plus économique à produire que les soupapes connues antérieurement.
