Description
An einer Umlenkstelle der normalen Strömung des Betriebsmittels angeordnetes Sicherheitsventil mit Sitzumspülung Die Erfindung betrifft ein an einer Umlenkstelle der normalen Strömung des B@etriebsmittels angeordnetes S.icherheitsventü mit Sitzumspülung für Betriebsmittel, die zum Ablagern von Fremdkörpern, z. B. Verkrusten oder Auskristallisieren, neigen. Bei diesen Betriebsmitteln besteht die Gefahr, daß das Ventil infolge der Ablagerungen bei eintretendem Überdruck: nicht rechtzeitig öffnet. Diese Gefahr hat ihre Ursache darin, daß das Sicherheitsventil im normalen Betrieb dauernd geschlossen ist und daß der Betriebsstoff im Eintrittsstutzen der üblichen Sicherheitsventile ohne Bewegung ist. Das ist nicht nur bei Sicherheitsventilen, die an Behältern angebracht sind, der Fall, sondern auch bei solchen, die in Leitungen angeordnet sind. Zwar liegt im letzteren Falle der Ventilsitz näher an der Strömung des Betriebsmittels; unmittelbar am Sitz ist das Betriebsmittel aber ohne Bewegung, so daß hier Ablagerungen erfolgen können. Das. ist auch bei bekannten Sicherheitsventilen mit Sitzumspültmg der Fall. Bei ihnen wird die Strömung nach den `bei Ventilen. üblichen Gesetzen den Weg des geringsten -Widerstandes suchen rund die Dichtungsstellen des Ventilkegels vollkommen unberührt lassen.Arranged at a deflection point of the normal flow of the operating fluid Safety valve with rinsing around the seat The invention relates to a valve at a deflection point the normal flow of the operating material arranged safety valve with seat circulation for equipment that is used to deposit foreign bodies, e.g. B. crusts or crystallization, tend. With these resources there is a risk that the valve as a result of Deposits when overpressure occurs: does not open in time. This danger is caused by the fact that the safety valve closes continuously during normal operation and that the fuel is in the inlet nozzle of the usual safety valves is without movement. This is not only the case with safety valves that are attached to containers are the case, but also with those that are arranged in lines. Though in the latter case, the valve seat is closer to the flow of the operating medium; directly at the seat, however, the equipment is without movement, so that deposits are formed here can be done. That. is also in known safety valves with Sitzumspänemg the case. With them the flow is according to the `with valves. usual laws look for the path of least resistance around the sealing points of the valve cone leave completely untouched.
Diese Mä;agel werden, gemäß der Erfindung dadurch vermieden, daß .der Einströmstützen unmittelbar unter dem Ventilkörper mündet und einen. Durchmesser besitzt, der kleiner ist als der des konzentrisch zu ihm angeordneten Ventilsitzes, wobei der Ventilkörper zweckmäßig mit einem kegelförmigen Vorsprung in den Einströmstutzen hineinragt. In dieser Form ist das neue S:iclherheitsventil nicht nur in Leitungen, sondern ,auch an Behältern anwendbar, soweit es dort nur in der Strömung des Betriebsmittels liegt.These flaws are avoided according to the invention in that .the Inflow supports opens directly under the valve body and one. diameter which is smaller than that of the valve seat arranged concentrically to it, the valve body expediently having a conical projection in the inflow connection protrudes. In this form, the new safety valve is not only available in lines, but can also be used on containers as long as it is only in the flow of the operating medium there lies.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt: Die Strömung des Betriebsmittels tritt bei f ein und wird durch den Krümmer im Innern des Gehäuses in die Richtung,der Achse des Ventilsitzes geleitet. Die Strömung trifft dabei auf den Boden des Ventilkörpers ä und wird durch :dessen besondere Form auf die Dichtflächen 3 hingelenkt. Über einen ringförmigen Querschnitt q. gelangt das Betriebsmittel dann zum Austritt 5.An embodiment of the invention is shown in the drawing: The flow of the operating fluid enters at f and is through the bend inside of the housing in the direction of the axis of the valve seat. The current hits while on the bottom of the valve body ä and is due to: its special shape on the sealing surfaces 3 articulated. Over an annular cross-section q. gets that Equipment then to exit 5.
Auf diese Weise werden die Dichtflächen des Ventils wirksam bespült, so daß sich keinerlei Fremdkörper an den Dichtflächen absetzen können. Diejenigen Fremdkörper, die sich bei Betriebsstillstand abgelagert haben sollten, werden bei Inbetriebnahme durch die Strömung leicht fortgespült.In this way, the sealing surfaces of the valve are effectively flushed, so that no foreign bodies can settle on the sealing surfaces. Those Foreign bodies that should have deposited during standstill are removed from Commissioning easily washed away by the current.
Der Ausströmstutzen 6 kann durch eine über den Anschluß 7 verbundene Spülleitung gereinigt werden, so daß auch Verkrustungen oberhalb des. Sitzes 3 nach Abblasen des Sicherheitsventils den Ventilkörper nicht beeinträchtigen können.The outflow nozzle 6 can be connected by a connector 7 Flushing line to be cleaned, so that incrustations above the. Seat 3 after Blowing off the safety valve cannot affect the valve body.
Die übrige Ausbildung des Sicherheitsventils kann in beliebiger bekannter Weise gestaltet sein.The rest of the design of the safety valve can be any known Be designed wisely.
