Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenstand vorliegender Erfindung ist ein vereinigtes Absperr- und Sicherheitsventil für Gase beliebigen Druckes. Dasselbe ist auf der Zeichnung in einer Ausführungsform dargestellt. The present invention is a combined shut-off and safety valve for Gases of any pressure. The same is shown in the drawing in one embodiment.

Das Ventil besteht aus dem durch die Spindel α bewegten Absperrventilkegel b, welcher den Ventilsitz c schliefst.. Dieser Sitz c ist ebenfalls als Ventilkegel ausgebildet und steht mit der Laterne c1 und dem im Stopfbüchsengehäuse des Ventils auf und ab beweglichen Stück c2 in fester Verbindung. Durch eine Feder d, welche dem festgesetzten Drucke für die Auslösung des Sicherheitsventils entspricht, wird der Sitz c festgeprefst, während die unter derselben angeordnete Stopfbüchse e aus Leder, Gummi, Metallpackungen oder sonst einem dem betreffenden Gase zweckentsprechenden Material den gasdichten Abschlufs nach aufsen bewirkt und damit die Verwendung des Ventils zum genannten Zwecke ermöglichen.The valve consists of the shut-off valve cone b moved by the spindle α , which closes the valve seat c. This seat c is also designed as a valve cone and is fixed with the lantern c 1 and the piece c 2 that can move up and down in the stuffing box housing of the valve Link. The seat c is pressed tight by a spring d, which corresponds to the set pressure for triggering the safety valve, while the stuffing box e, made of leather, rubber, metal packing or any other material suitable for the gas in question, causes the gas-tight seal to the outside and thus enable the use of the valve for the stated purpose.

In dem Stück c2 ist ebenfalls eine Stopfbüchse für die Spindel α vorgesehen.In the piece c 2 a stuffing box for the spindle α is also provided.

Die Art des Abschlusses der Ventilkegel mit dem Sitz ist hierbei nur in einer Ausführungsform dargestellt, der Abschlufs derselben kann aber auch auf eine andere Weise erzielt werden, z. B. durch Einlegen eines geeigneten Abdichtungsringes in dem dazu ausgebildeten Ventilkegel oder Sitz.The type of closure of the valve cone with the seat is only shown in one embodiment, the closure of the same but can also be achieved in another way, e.g. B. by inserting a suitable sealing ring in the valve cone or seat designed for this purpose.

Die Wirkungsweise des Ventils ist nun folgende: The mode of operation of the valve is now as follows:

Für gewöhnlich dient das Ventil als Absperrventil und kann der Kegel b durch die Spindel α mit Handrad gehoben oder auf den Sitz c geprefst werden. Für den Fall aber, dafs durch ein Versehen das Ventil nicht rechtzeitig geöffnet würde und infolge dessen der Druck hinter dem Ventil über den zulässigen steigt, so wirkt das Ventil als Sicherheitsventil, indem der Druck des Gases unter Ueberwindung des Federdruckes d den Sitz c zusammen mit Ventil b aufhebt und dadurch dem Gase gestattet, zu entweichen;Usually the valve serves as a shut-off valve and the cone b can be lifted by the spindle α with a handwheel or pressed onto the seat c. However, in the event that the valve is not opened in time by mistake and as a result the pressure behind the valve rises above the permissible level, the valve acts as a safety valve in that the pressure of the gas, overcoming the spring pressure d, works together with the seat c Valve b cancels, thereby allowing the gases to escape;

Da sich beim Heben des Sitzes c auch die Spindel α mit bewegt, so wird durch den Maschinisten leicht der Fehler bemerkt, aufserdem kann auch durch diese Bewegung leicht eine zweckmäfsig angeordnete Alarmvorrichtung verbunden werden.Since the spindle α also moves when the seat c is raised, the machine operator can easily notice the error, and an appropriately arranged alarm device can also easily be connected by this movement.
