Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei der in der Patentschrift 91225 dargestellten Maschine zur Prüfung von beliebigen Rohrkrümmern auf inneren Druck wirkt der zum Abdichten der Verschlufsscheiben an den Rohrenden erforderliche Druck biegend und verdrehend auf die beiden im Winkel zu einander verstellbaren Wangen, wodurch eine unübersichtliche und für den hohen Prüfungsdruck von 20 Atm. sehr schwerfällige Bauart bedingt wird.In the case of the patent 91225 shown Machine for testing any pipe elbows for internal pressure, which acts to seal the sealing disks on the Pipe ends required bending and twisting pressure on the two at an angle to each other adjustable cheeks, creating a confusing and for the high test pressure of 20 Atm. very clumsy design is conditioned.

Diese Nachtheile werden durch die auf beiliegender Zeichnung, und zwar in Fig. 1 im Aufrifs, in Fig. 2 im Grundrifs und in Fig. 3 in der Seitenansicht dargestellte Anordnung beseitigt. These disadvantages are caused by the attached drawing, namely in Fig. 1 in Aufrifs, in Fig. 2 in the Grundrifs and in Fig. 3 in the side view eliminated the arrangement.

Die beiden Verschlufsscheiben α und b sind auf Rollen laufend verschiebbar auf den beiden Gestellen c und d angeordnet, von denen das eine c festliegt und an einem Ende einen Zapfen trägt, um welchen das andere Gestell d schwingt, wobei das freie Ende e des letzteren mittelst Rollen auf einer halbkreisförmig gebogenen Schiene f läuft. Zur unmittelbaren Aufnahme des Druckes dienen die mit Gewinde versehenen vier Zugstangen g, welche scharnierartig mit einem Bügel h verbunden sind, der eine durch die Spindel i und das Handrad k verstellbare Druckscheibe / trägt. Die Verschlufsscheiben a und b können durch die mit Muttergewinde versehenen Handräder m an die Rohrenden angeprefst werden.The two locking disks α and b are continuously slidable on rollers on the two frames c and d , one of which c is fixed and at one end carries a pin around which the other frame d swings, the free end e of the latter in the middle Rolls on a semicircular curved rail f runs. The four threaded tie rods g, which are connected in a hinge-like manner to a bracket h , which carries a pressure disk / adjustable by the spindle i and the handwheel k, serve to directly absorb the pressure. The locking washers a and b can be pressed against the pipe ends by means of the handwheels m fitted with a nut thread.

Soll ein Rohr geprüft werden, so wird zunächst das Gestell d in eine dem Rohrkrümmer entsprechende Winkelstellung zu c gebracht, sodann werden die Verschlufsscheiben α und b, welche die erforderlichen Luftentleerungs- und Wasserzuführungsvorrichtungen enthalten, gegen die Rohrenden geschoben und vermittelst der Handräder m fest an dieselben angeprefst.If a pipe is to be tested, the frame d is first brought into an angular position corresponding to the pipe bend to c , then the locking disks α and b, which contain the necessary air evacuation and water supply devices, are pushed against the pipe ends and fixed by means of the handwheels m the same apprefst.

Claims (1)

Patent-Anspruch:Patent claim: Maschine zur Prüfung von Knierohren durch inneren Wasserdruck nach Patent 91225, dadurch gekennzeichnet, dafs die Verschlufsscheiben (a und b) durch Zugstangen (g) verbunden sind, welche vermittelst eines Druckbügels (h) den zum Abdichten der Verschlufsscheiben (a und b) an den Rohrenden erforderlichen Druck aufnehmen, so dafs die in beliebigem Winkel zu einander verstellbaren Gestelle (c und d) diesem Druck nicht mehr ausgesetzt sind, sondern nur noch zur Unterstützung und bequemen Einstellung der Verschlufsscheiben (a und b) dienen.Machine for testing knee tubes by internal water pressure according to patent 91225, characterized in that the locking washers (a and b) are connected by tie rods (g) which, by means of a pressure bracket (h), are used to seal the locking washers (a and b) to the The pipe ends absorb the required pressure so that the frames (c and d), which can be adjusted at any angle to each other, are no longer exposed to this pressure, but only serve to support and conveniently adjust the locking disks (a and b).
