Description
Die Erfindung betrifft eine verschleißfeste Armatur für strömende Stoffe, und zwar insbesondere eine Absperr- oder Regelarmtur wie z.B. ein Durchgangevent 11.The invention relates to a wear-resistant valve for flowing substances, in particular a shut-off or control armature such as a transit event 11.
Bei solchen Armaturen unterliegen die mit den strömenden Stoffen in Berührung kommenden Teile« wie vor allem die Drosselorgane, die Zu« und Abströmkanal« bzw* die Innenwandungen derselben oft einem starken VersohleIS, sei es durch mechanlsohe und/oder chemische Einwirkungen der strömenden Stoffe bzw« Medien.In such fittings, the parts that come into contact with the flowing substances are subject to «as above all the throttle organs, the inlet and outlet ducts or the Inner walls of the same often have a strong sole, be it through mechanical and / or chemical effects of flowing substances or media.
Es ist bereits bekannt, zwecks Vermeidung oder Milderung solcher Einwirkungen für die dem Ver schiel β ausgesetzten Bauteile besondere verschleißfeste bzw. säurefeste Werkstoffe in Form von Auskleidungen od.dgl. zu verwenden, die in das Armaturgehäuse eingesetzt werden. Da diese Bauteile aber auoh hohen FestlgkeltsansprUehen genügen müssen und nicht zu teuer sein dürfen, β tu 8t die Auswahl von geeigneten Werkstoffen dieser Art auf Schwierigkeiten. Ire allgemeinen wurden für diese Zwecke Teile aus hochfestem Stahl, Hartmetall oder Oxyttkeramlk benutzt.It is already known, in order to avoid or mitigate such effects for the United squint β exposed components special wear-resistant or acid-resistant materials in the form of linings or the like. to be used, which are inserted into the valve body. But since these components also have high rigidity requirements have to be sufficient and not be too expensive, that is what they do Selection of suitable materials of this type based on difficulties. In general, parts made of high-strength steel, hard metal or oxyte-ceramic were used for this purpose.
Nun bringen a^ber auch die Slnbaubedingungen in das zu Benutzende Armaturgehttuse weitere Schwierigkeiten mit sich« wie z.B. die unterschiedlichen Dehnungsverhältnisse· die geringe Biegefestigkeit oder ein ungünstiges Thermosehoekverhalten vieler derartiger Werkstoffe.Now the building conditions also bring in The fitting to be used poses further difficulties with itself «such as the different expansion ratios the low flexural strength or unfavorable thermosehoek behavior of many such materials.
Oer Erfindung liegt die Aufgabe zugrunde, verschleißfeste Armaturen der eingangs gengtnnten Art zu schilf fen, welche die Mängel der bekannten Armaturen vermeiden. The invention is based on the object of providing wear-resistant fittings of the type mentioned in the introduction reeds, which avoid the shortcomings of the known fittings.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die der Einwirkung der strömenden Stoffe ausgesetzten bzw. dem YersohleiS unterliegenden Teile der Armatur aus Siliciumnitrid (8IJR4) oder aus Siliciumcarbid (SiC) bzw. aus Verbindungen dieser Stoffe bestehen.This object is achieved according to the invention in that the parts of the fitting exposed to the action of the flowing substances or subject to YersohleiS consist of silicon nitride (8IJR 4 ) or silicon carbide (SiC) or compounds of these substances.
3s hat sich gezeigt, daß diese Werkstoffe !igen* schäften In sich vereinigen, welche sie für die Verwendung in verschleißfesten Armaturen besondere geeignet machen. So weisen diese werkstoffe außer ihrer erheblich größeren Verschleißfestigkeit auch eine größere Biege- und Thermoschockfestlgkelt, eine höhere Temperaturfestigkeit undIt has been shown that these materials unite in themselves what they are used for make them particularly suitable in wear-resistant fittings. So these materials have, in addition to their considerably larger Wear resistance also has a greater resistance to bending and thermal shock, a higher temperature resistance and
außerdem eine höhere chemische Beständigkeit auf. Armaturen gemäB der Erfindung haben daher eine erheblich bessere Standzeit bzw. Lebensdauer als die bisher Üblichen Armaturen.also has a higher chemical resistance. Fittings according to the invention therefore have a considerable better service life or service life than the fittings that have been customary up to now.
ErfindungsgemSB werden die Werkstoffe Siliciumnitrid oder Sllielumkarbld vor allem verwendet für die Absperr· und Srosselorgane« wie Ventilsitze» Ventilkegel« als Auskleidungen von Oehäuselnnenwänden« wie Zu- UBodt und Abströmkanälen usw.According to the invention, the materials are silicon nitride or Sllielumkarbld mainly used for the shut-off and throttling organs, such as valve seats, valve cones as linings of the inner walls of the house «like Inflow, bottom and outflow channels, etc.
In der Zeichnung sind zwei AusfUhrungsbeispiele der Erfindung veranschaulicht.There are two exemplary embodiments in the drawing of the invention.
91g. 1 zeigt ein Durchströmventil mit winkelförmiger Durchgangsriehtung, und91g. 1 shows a flow-through valve with an angular passage arrangement, and
Flg. 2 zeigt ein Durchgangsvent11 mit gerader Durchgangsrichtung.Flg. 2 shows a through valve 11 with a straight line Passage direction.
Bei den gezeigten Ventilen bestehen vor allem der Ventilsitzkörper 1 und der Ventilkegel 2 aus Siliciumnitrid oder Siliciumcarbid. Je nach der Bauart und denIn the valves shown, the valve seat body 1 and the valve cone 2 are primarily made of silicon nitride or silicon carbide. Depending on the type and the
Strömungsverhältnissen werden auoh die Auskleidungskörper 3 für den Abströmkanal odeijlen Zuströmkanal aus diesen Werkstoffen hergestellt. Ebenso können entsprechende Auskleidungen für sonstige Innentelle oder Innenwandungen der Armaturen verwendet werden.Flow conditions are also the lining bodies 3 for the outflow channel or inflow channel made from these materials. Corresponding linings for other internal parts or Inner walls of the fittings are used.
Zum Einbau der Siliciumnitrid- oder Sillclumoarbidkörper. Insbesondere der Ventllsltzkörper 1 oder der Auskleidungskörper 3, können Dichtungen bzw. elastische Zwischenstücke 4 zwischen diesen Körpern und den Metallteilen des Armaturgehäuses angeordnet werden. OenäS einer praktischen Ausführung eines erfindungsgemäßen Ventils kann der Ventilsitzkörper 1 zwischen zwei Gehäuseteilen 5 und 6 eingebaut sein.For the installation of silicon nitride or silicon carbide bodies. In particular, the valve body 1 or the lining body 3, seals or elastic Intermediate pieces 4 between these bodies and the metal parts of the valve body are arranged. OenäS a practical embodiment of a valve according to the invention the valve seat body 1 can be installed between two housing parts 5 and 6.
Im übrigen beschränkt sich die Erfindung nicht auf die vorstehend beschriebenen und in der Zeichnung veranschaulichten Ausführungsformen. Diese stellen nur Beispiele für die In Verwendung der Werkstoffe Siliciumnitrid oder/und Siliciumcarbid für verschlelSfeste Armaturen der genannten Art dar.Otherwise, the invention is not limited to those described above and in the drawing illustrated embodiments. These only represent Examples of the use of the materials silicon nitride and / or silicon carbide for encryption-proof fittings of the type mentioned.
