KLASSE 8B: Wasserleitung.CLASS 8B: water pipe.
Patentirt im Deutschen Reiche vom 3. Februar 1888 ab.Patented in the German Empire on February 3, 1888.
Auf beiliegender Zeichnung sind einige Abänderungen des unter No. 36254 patentirten Aüsflufshahnes dargestellt.In the accompanying drawing, some changes to the information given under No. 36254 patented Aüsflufshahnes shown.
In Fig. ι ist statt der cylindrischen hohlen Stange b, welche das Küken der gewöhnlichen Hähne ersetzt, ein hohler, an einer Seite offener Kolben b angewendet, welcher Oeffnungen a a1 besitzt. : Dieser Kolben ist durch eine Stopfbüchse, Lederstulpe u. s. w. c im Gehäuse dicht, geführt und wird durch den Druck in der Leitung in der Richtung des Pfeiles 1 bewegt, bis er gegen das Excenter d stöfst. Letzteres ist nun so angebracht, dafs der Kolben in seiner höchsten Stellung den Hahn schliefst, d.h. die Durchlafsöffnungen α α1 von der Stopfbüchse c verdeckt sind, also kein Wasser durchlassen. Soll der Hahn geöffnet werden, so dreht man das Excenter d so, dafs der Kolben b zurückgedrückt wird, bis die Oeffnungen α al nicht mehr von der Stopfbüchse c verdeckt werden, sondern freiliegen und dem Wasser den Durchgang gestatten. Bei dem Hahn Fig. 2 ist die Wirkung eine umgekehrte, da der Kolben b seine, offene Seite der Druckrichtung entgegensetzt. Hier öffnet der Druck in der Leitung den Hahn, während derselbe durch Drehung des Excenters in Richtung des Pfeiles geschlossen wird. An Stelle des Excenters kann man auch durch irgend eine andere Vorrichtung auf den Kolben b einwirken.In Fig. 1, instead of the cylindrical hollow rod b, which replaces the plug of the common cocks, a hollow piston b , which is open on one side and which has openings aa 1 , is used. : This piston is tightly guided by a stuffing box, leather cuff, etc. c in the housing and is moved in the direction of arrow 1 by the pressure in the line until it hits the eccentric d . The latter is now attached in such a way that the piston closes the cock in its highest position, ie the passage openings α α 1 are covered by the stuffing box c , so do not let water through. If the cock is to be opened, the eccentric d is turned so that the piston b is pushed back until the openings α a l are no longer covered by the stuffing box c , but are exposed and allow the water to pass through. In the case of the valve in FIG. 2, the effect is reversed, since the piston b opposes its open side in the direction of pressure. Here the pressure in the line opens the cock, while the cock is closed by turning the eccentric in the direction of the arrow. Instead of the eccentric one can also act on the piston b by some other device.
Durch die Abänderung Fig. 3 wird hauptsächlich eine Veiiangsamung der Bewegung des Kolbens b bezweckt. Der Kolben b endigt in eine Stange h mit Knopf h1 und sein Durchgang im Hahnkörper ist durch die Stopfbüchsen c cl abgedichtet. Das Wasser nimmt seinen Weg von der Leitung aus durch die Oeffnungen k und α in den hohlen Theil des Kolbens b und gelangt von hier durch die Oeffnungen g in den Ausflufs i. In normalem Zustande ist der Hahn geschlossen, da der Druck in der Leitung den Kolben b so weit zurückdrängt, dafs die Oeffnungen α α von der Stopfbüchse c verdeckt werden. Wird der Kolben b durch Druck auf den Knopf h1 ganz verschoben, so dafs die Oeffnungen g von der Stopfbüchse c,· die Oeffnungen α von derjenigen c1 verdeckt werden, so bleibt der Hahn so lange geschlossen, als der Druck auf den" Knopf h1. fortdauert. Hört nun dieser Druck auf, so öffnet sich der Hahn durch den auf die Fläche m ausgeübten Druck der Leitung und schliefst sich alsdann langsam wieder dadurch, dafs die Oeffnungen α allmälig in die Stopfbüchse c eintreten und von dieser verdeckt werden. Dieses langsame Zurückgehen des Kolbens b wird dadurch bewirkt, dafs der Druck der Leitung bezw. das Wasser nichi direct auf die Fläche m drücken kann, sondern erst in die Kammer e eindringen mufs. Die Kammer e schliefst nämlich vermittelst der Stopfbüchse c1 nicht ganz dicht um den Kolben b, so dafs das Wasser ganz allmälig in die Kammer e eintreten kann und so langsam den Kolben b zurückdrängt.The modification of FIG. 3 mainly aims at increasing the movement of the piston b . The piston b ends in a rod h with button h 1 and its passage in the valve body is sealed by the stuffing boxes cc l. The water takes its way from the line through the openings k and α into the hollow part of the piston b and from here passes through the openings g into the outflow i. In the normal state the cock is closed because the pressure in the line pushes the piston b back so far that the openings α α are covered by the stuffing box c . If the piston b is completely displaced by pressing the button h 1 , so that the openings g are covered by the stuffing box c and the openings α are covered by that c 1 , the cock remains closed as long as the pressure is applied to the "button h 1. If this pressure ceases, the valve opens due to the pressure exerted by the line on the surface m and then slowly closes again as the openings α gradually enter the stuffing box c and are covered by it. this slow return of the piston b is effected by the pressure of the line DAF BEZW. the water nichi directly on the surface can press m, but only in the chamber e penetrate PUFA. the chamber e asleep namely not by means of the gland c 1 very close around the piston b, so that the water can gradually enter the chamber e and slowly push back the piston b.
