Description
Die Erfindung bezweckt eine weitere Ausbildung der Parallelschieber mit selbsttätiger Entlastung nach, dem Hauptpatent. Sie besteht darin, daß die Entlastungsventile in die Gehäusehaube eingesetzt und im Haubenstutzen des Schiebergehäuses Überströmkanäle vorgesehen sind, an welchen sich die Bohrungen der Ventilsitze der Entlastungsventile anschließen. Dadurch wird die Bauweise des Schiebers vereinfacht und vor allem der Vorteil erreicht, daß für die Entlastungsvorrichtung keine Rohrleitungen erforderlich sind.The invention aims at a further development of the parallel slide with automatic Relief according to the main patent. It consists in the relief valves in the housing hood is inserted and overflow ducts in the hood connector of the valve body are provided, to which the bores of the valve seats of the relief valves connect. This will make the construction the slide is simplified and, above all, the advantage achieved that for the relief device no piping is required.
Der Gegenstand der Erfindung wird an Hand eines in den Abb. 1 bis 4 dargestellten Ausführungsbeispiels erläutert.The object of the invention is illustrated by means of one in FIGS Embodiment explained.
Abb. ι stellt einen senkrechten Mittenschnitt durch das Ventil dar undFig. Ι shows a vertical center section through the valve and
Abb. 2 einen Schnitt nach der Linie A-B der Abb. 1.Fig. 2 shows a section along the line AB in Fig. 1.
Abb. 3 zeigt den Mittenschnitt durch das Entlastungsventil in vergrößertem Maßstabe undFig. 3 shows the center section through the relief valve on an enlarged scale and
Abb. 4 einen Schnitt nach der Linie C-D der Abb. 3.Fig. 4 shows a section along the line CD in Fig. 3.
Beim Öffnen des Ventils, also bei der Aufwärtsbewegung der Spindel 30 und Bolzen 31 schwenken die letzteren die Steuerhebel 32 um die Achsen 33. Die Steuerhebel heben dabei die Ringe 34, welche die Führungszylinder 35 der Kolbenkörper 38 der Entlastungsventile konzentrisch umfassen. Die Ringe 34 sind mit Bolzen 36 versehen, welche durch Schlitze yj der Führungszylinder 35 hindurch unter einen Absatz der Ventilkörper 38 greifen. Beim Öffnen der Entlastungsventile strömt der Dampf durch die Gehäusekanäle 39, die Schlitze 37 und die Kammer 40 und führt so einen Druckausgleich zwischen den beiderseits des Schiebers liegenden Rohrleitungen herbei.When the valve is opened, i.e. when the spindle 30 and bolt 31 move upwards, the latter pivot the control levers 32 about the axes 33. The control levers raise the rings 34, which concentrically encompass the guide cylinders 35 of the piston bodies 38 of the relief valves. The rings 34 are provided with bolts 36 which engage through slots yj of the guide cylinder 35 under a shoulder of the valve body 38. When the relief valves are opened, the steam flows through the housing channels 39, the slots 37 and the chamber 40 and thus brings about a pressure equalization between the pipelines lying on both sides of the slide.
Nach Entfernen der Deckel 41 können die Ventilkörper 38 ausgebaut werden, ohne daß es nötig ist, die Haube 42 vom Haubenstutzen 43 abzunehmen. Das Ein- und Ausbauen der Schieberplatten bei abgenommener Haube ist ebenso einfach wie beim Gegenstand des Hauptpatents. " ·After removing the cover 41, the valve body 38 can be removed without it is necessary to remove the hood 42 from the hood connector 43. The installation and removal the slide plates with the hood removed is just as simple as with the object of the Main patent. "·
