Description

DEUTSCHESGERMAN

Die Erfindung bezieht sich auf in Durchfluß richtung öffnende Hochhubsicherheitsventile mit einem vom abzusichernden Druck gesteuerten Hilfsventil und einem federbelas-teten, mit dem Hauptkegel verbundenen Stufenkolben. Bei derartigen Ventilen wird erfindungsgemäß eine Verbesserung vorgeschlagen, die darin besteht, daß eine Führung des kleineren Kolbens im Gehäuse des Hauptventils den Ringraum unter dem Hubkolben Tom Ventilaustritt trennt, wobei der Druck im Ringraum vom Hilfsventil bestimmt wird. Es ergibt sich dadurch die Möglichkeit, daß Nacharbeiten am Ventilsitz ausgeführt werden können, ohne den Boden zwischen Auspuff und Hubkolbenraum herausnehmen zu müssen. Ferner können, da der zwischen Auspuff- und Hubraum befindliche Boden im Gehäuse mit dem letzteren ein Ganzes bildet, die l>eiden Zylinder für den Stufenkolben und der Ventilsitz einwandfrei in einem Arbeitsgang- bearbeitet werden. Die Lage der Zylinder und des Ventilsitzes zueinander ist immer die gleiche, weshalb ein Verschieben dieser Teile gegeneinander, wie es bei bekannten Bauarten nach jedem Ausbau des Ventilkegels der Fall ist, nicht vorkommen kann.The invention relates to in the flow direction Opening high-lift safety valves with an auxiliary valve controlled by the pressure to be protected and a spring-loaded one connected to the main cone Stepped piston. In such valves, the invention proposes an improvement that is that a guide of the smaller piston in the housing of the main valve under the annulus the reciprocating piston Tom valve outlet separates, whereby the Pressure in the annulus is determined by the auxiliary valve. This results in the possibility of reworking can be carried out on the valve seat without the floor between the exhaust and the piston chamber to have to take out. Furthermore, because the floor located between the exhaust and displacement forms a whole in the housing with the latter, the two cylinders for the stepped piston and the valve seat can be processed perfectly in one operation. The location of the cylinders and the valve seat to each other is always the same, which is why a shift these parts against each other, as is the case with known designs after each removal of the valve cone is the case, cannot occur.

Der kleinere Kolben dient zur Führung des Hauptkegels. Ist er gemäß weiterer Ausbildung der obengenannten Erfindung nahe am Hauptkegel angeordnet, ergibt sich daraus als besonderer Vorteil, daß der Einfluß der seitlichen Anblasung des Ventilkegels auf die Bewegungen des Ventils auf ein Kleinstmaß verringert ist.The smaller piston is used to guide the main cone. Is he according to further training of the above Invention arranged close to the main cone, there is a particular advantage that the Influence of the lateral blowing of the valve cone on the movements of the valve to a minimum is decreased.

Weitere Einzelheiten sind aus der Beschreibung und Zeichnung zu entnehmen. Die letztere veranschaulicht ein Ausführungsbeispiel der Erfindung. Nach ihm 1>esteht das Gesamtaggregat aus einem Steuerventil 1 und einem Hauptventil 2. Beide Ventile sind durch eine Steuerleitung 3 miteinander verbunden.Further details can be found in the description and drawing. The latter illustrates an embodiment of the invention. According to him 1> the entire unit consists of a control valve 1 and a main valve 2. Both valves are connected to one another by a control line 3.

Der Kegel 11 des Hauptventils 2 wird durch den in Pfeilrichtung eintretenden Dampfdruck im öffnenden Sinne belastet. Dem wirkt die Feder 5 entgegen. Das Steuerventil 1 ist durch die Steuerfeder 4 so eingestellt, daß es beim gewünschten Abblasedruck in Tätigkeit tritt. Sobald sein Steuerkegel 14 gehoben wird, entsteht im Wasserabscheider 15, in der Steuerleitung 3 und damit im Raum 18 unter dem Hubkolben 6 ein Arbeitsdruck, welcher zunächst die überschüssige Kraft der Hauptfeder überwindet. Nunmehr steht der Hauptkegel 11 im Gleichgewicht, und der eigentliche Abblasevorgang kann eingeleitet werden. Mittels einer Drosselschraube 16 wird die Geschwindigkeit des Druckaufbaues und die Entleerung des Arbeitsdruckraumes eingeregelt, um ein weiches Arbeiten des Hauptventils zu erreichen.The cone 11 of the main valve 2 is loaded in the opening sense by the steam pressure entering in the direction of the arrow. The spring 5 counteracts this. The control valve 1 is set by the control spring 4 so that it comes into operation at the desired blow-off pressure. As soon as its control cone 14 is lifted, a working pressure arises in the water separator 15, in the control line 3 and thus in the space 18 under the reciprocating piston 6, which initially overcomes the excess force of the main spring. The main cone 11 is now in equilibrium and the actual blow-off process can be initiated. The speed of the pressure build-up and the emptying of the working pressure chamber are regulated by means of a throttle screw 16 in order to achieve smooth operation of the main valve.

Der Kolben des Hauptventils 2 ist, wie bereits oben erwähnt, erfindungsgemäß als Stufenkolben ausge-As already mentioned above, the piston of the main valve 2 is designed according to the invention as a stepped piston.

bildet. Der größere Kolben 6 gleitet dabei in dem als Zylinder 7 ausgebildeten oberen Teil des Gehäuses 8, während der kleinere Kolben 9 in einer als Zylinder gestalteten Führung 10 des zwischen Auspuffraum 17 und Hubraum 18 befindlichen Bodens 19 im Gehäuse 8 verschiebbar ist.forms. The larger piston 6 slides in the upper part of the housing 8 designed as a cylinder 7, while the smaller piston 9 is in a cylinder-shaped guide 10 between the exhaust chamber 17 and displacement 18 located bottom 19 in the housing 8 is displaceable.

Der Absperrkegel 11 des Hauptventils 2 ist im Durchmesser um ein geringes Maß kleiner als der Durchmesser des kleinen Kolbens 9. Dadurch ist es bei anfallenden Reparaturen am Ventilkegel 11 möglich, diesen mitsamt dem gesamten Oberteil des Hauptventils in einem abzunehmen. Es braucht hierzu lediglich die Verbindung der Flansche 12 gelöst zu werden.The shut-off cone 11 of the main valve 2 is slightly smaller than that in diameter Diameter of the small piston 9. This makes it possible for repairs to be made to the valve cone 11, remove this together with the entire upper part of the main valve in one. It takes this only the connection of the flanges 12 to be released.
