VentilValve
Die vorliegende Erfindung bezieht sich auf ein Ventil, insbesondere ein Kugelventil, gemäß dem Oberbegriff des Hauptanspruchs.The present invention relates to a valve, in particular a ball valve, according to the preamble of the main claim.
Solche Ventile werden insbesondere als Gasabsperrhähne eingesetzt, wie sie gasbeheizten Geräten vorgeschaltet sind. Hierbei besteht die Forderung, daß die Ventile einerseits leichtgängig im Normalzustand und gasdicht sowohl im Normalzustand als auch im Brandfalle sind. Da die Ventile Gummi- bzw. Kunststoffdichtungen enthalten und diese im Brandfall über ihre zulässige Betriebstemperatur hinaus erhitzt werden, werden bei erhöhten Umgebungstemperaturen derartige Gasabsperrventile undicht.Such valves are used in particular as gas shut-off valves, as they are connected upstream of gas-heated devices are. There is a requirement here that the valves on the one hand smoothly in the normal state and gas-tight are both in the normal state and in the event of fire. Because the valves contain rubber or plastic seals and these are heated above their permissible operating temperature in the event of a fire such gas shut-off valves leak at elevated ambient temperatures.
Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, ein solches Ventil auch bei erhöhten Umgebungstemperaturen gasdicht beziehungsweise auf Gasdurchgang mit definierbarer Leckrate zu gestalten. Die Lösung der Aufgabe Hegt in den kennzeichnenden Merkmalen des Hauptanspruchs. Weitere Ausgestaltungen und besonders vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche beziehungsweise gehen aus der nachfolgenden Beschreibung hervor, die ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert.The present invention is therefore based on the object of designing such a valve in a gas-tight manner even at elevated ambient temperatures or for gas passage with a definable leak rate. The solution to the problem lies in the characterizing features of the main claim. Further refinements and particularly advantageous developments of the invention are the subject matter of the subclaims or emerge from the following description, which explains an embodiment of the invention in more detail with reference to the drawing.

Das in der Zeichnung dargestellte Kugel-Gasabsperrventi1 weist ein Gehäuse (1) auf, das eine Gaseinlaßöffnung (2) und eine Gasablaßöffnung (2) aufweist. Diese öffnungen sind mit Außengewinde versehen, so daß weiterführende Anschlußleitungen angebracht werden können. Im zentralen Innenraum (4) ist eine kugelige Innenoberfläche (5) eines Hohlraumes ausgearbeitet, in der eine Kugel (6)The ball gas shut-off valve shown in the drawing has a housing (1) which has a gas inlet opening (2) and a gas discharge opening (2). These openings are provided with external threads, so that further Connection lines can be attached. In the central Inner space (4) is a spherical inner surface (5) of a cavity in which a ball (6)

Die Kugel weist zwei zueinander senkrechte Bohrungen (10 + 11) auf, wobei die Bohrung (10) durch die Kugel hindurchgeht, während die senkrecht darzustellende Bohrung (11) von der Oberseite bis in den Mittenbereich zur Bohrung (10) reicht.on, in which an actuating pin (8) engages, which is rotatable by means of a handle (9). The ball has two perpendicular holes (10 + 11) on, the hole (10) going through the ball, while the hole (11) to be shown vertically from the top to the middle area to the hole (10) is enough.
Oe nach Stellung der Bohrungen können Aus- und Einlaß (2 + 3) miteinander verbunden werden oder voneinander getrennt werden.Depending on the position of the bores, outlet and inlet (2 + 3) can be connected or separated from each other.
In einer Schrägfläche (12), bezogen auf die Lage des Auslasses (2) und des Einlasses (3) ist eine Nut (13) eingearbeitet, in die ein Dichtring (14) eingelegt ist. Dieser Dichtring (14) steht über die Nut (13)" hervor, lehnt sich im Normalfall an die Außenwandung der Kugel an und umgibt etwa kreisförmig den Teil des Auslasses (2), der mit dem Innenraum (4) in Verbindung steht.In an inclined surface (12), based on the position of the outlet (2) and the inlet (3), a groove (13) is incorporated into which a sealing ring (14) is inserted. This sealing ring (14) protrudes beyond the groove (13) ″, normally leans against the outer wall of the ball and surrounds the part of the outlet (2) that is connected to the interior (4) in an approximately circular manner.
Auf der dem Auslaß (2) gegenüberliegenden Seite sind auf einer Schulter (15) eine oder mehrere Bimetallringscheiben (16) gelagert, die sich unmittelbar an der Wandung der Kugel (6) abstützen.On the side opposite the outlet (2) one or more bimetallic ring disks (16) mounted on a shoulder (15), which are located directly Support on the wall of the ball (6).
Im Normaifali dichtet der Dichtring (14) die Kugel gegenüber dem Auslaßstutzen (2) ab, wenn die Bohrung (10) rechtwinklig zum Auslaß (Z) gedreht wird in Stellung "geschlossen". In normal practice, the sealing ring (14) seals the ball against the outlet connection (2) when the bore (10) is rotated at right angles to the outlet (Z) to the "closed" position. Tritt nun ein Brandfall auf, das heißt, entstehen gegenüber der normalen Raumtemperatur überhöhte Temperaturen, so beginnt sich das oder die Bimetalle (16) zu verformen, das heißt, die Kugel wird verstärkt gegen den Dichtring (14) gepreßt. Andererseits wird sich aufgrund der erhöhten Umgebungstemperatur der Dichtring verformen beziehungsweise sogar verkoken, so daß er seine eigentliche Dichtfunktion nicht mehr wahrnehmen kann. Aufgrund der Verformung des oder der Bimetalle wird aber die Kugel dann gegen die Schrägfläche (12) angeglegt, so daß zwischen Kugel und Gehäuseinnenwandung eine metallische Dichtung bewirkt wird.If a fire now occurs, that is, the room temperature is excessive compared to the normal room temperature Temperatures, the bimetal or bimetal (16) begins to deform, that is, the ball is reinforced pressed against the sealing ring (14). On the other hand, due to the increased ambient temperature, the Deform sealing ring or even coke so that it no longer performs its actual sealing function can perceive. However, due to the deformation of the bimetal or bimetal, the ball is then against the Inclined surface (12) applied so that a metallic seal between the ball and the inner wall of the housing is effected.
Damit bleibt das stromab des Gasabsperrventils angeordnete gasbeheizte Gerät von der Gaszufuhr im Brandfall abgeschlossen. Nach Absenken der Temperatur 1m Aufstellungsraum des Gasabsperrventils würde zwar wieder eine Undichtigkeit auftreten, da die Bimetalle in ihre Ursprungslage zurückgehen, man kann aber davon ausgehen, daß inzwischen aufgrund des Brandes das Hauptgasventil des Hauses oder der Wohnung geschlossen wurde, das in einem anderen Raum angeordnet 1st als das dem gasbeheizten Gerät unmittelbar vorgeschaltete Gasventil.In this way, the gas-heated device arranged downstream of the gas shut-off valve remains shut off from the gas supply in the event of a fire. After lowering the temperature 1m in the room where the gas shut-off valve would be Again a leak will occur because the bimetals go back to their original position, but it can be assumed that in the meantime due to the fire the main gas valve of the house or apartment has been closed, which is located in another room 1st as the gas valve directly upstream of the gas-heated device.
Es sei noch darauf hingewiesen, daß die Anwendung der Erfindung nicht auf Kugelventile beschränkt ist, ebenso könnte der Wälzkörper (4) als Zylinder oder als Schieber ausgebildet sein.It should be noted that the application of the invention is not limited to ball valves, as could the rolling element (4) as a cylinder or be designed as a slide.
• - ι ·• - ι ·
Wesentlich ist, daß der beliebig geformte Ventilkörper unter der Einwirkung eines Bimetalls bei erhöhten Umgebungstemperaturen gegen eine sonst nicht wirksame Dichtfläche gepreßt wird, weil die eigentliche Dichtfläche aufgrund der erhöhten Umgebungstemperatur ausgefallen ist.It is essential that the arbitrarily shaped valve body under the action of a bimetal at increased Ambient temperatures is pressed against an otherwise ineffective sealing surface because the actual The sealing surface has failed due to the increased ambient temperature.
