Description

Als bekannt werden Absperrschieber, vor allen Dingen für Hochdruckleitungen vorausgesetzt, mit einem Dichtungskeil aus zwei getrennten Hälften, welche auf mannigfache, mehr oder weniger kostspielige' Art durch Spindeldruck mittels Gelenken, Keilen usw. gegen die Sitzflächen gepreßt werden.Gate valves are known, especially for high pressure pipes provided with a sealing wedge made of two separate halves, which are more or less expensive 'type by spindle pressure by means of joints, wedges etc. are pressed against the seat surfaces.

Die in großer Mehrzahl gebräuchlichen Absperrschieber für Niederdruckleitungen sind mit einem Dichtungskeil aus einem einzigen Guß- oder Schweißstück ausgerüstet.The majority of the gate valves for low-pressure lines are equipped with a sealing wedge made from a single cast or welded piece.

Die bei Verwendung dieser Schieber oftmals nicht genügende Abdichtung hat häufig ihre Ursache in einer Verspannung des Gehäuses, entstanden durch bei der Montage fest angezogene klaffende Flansche oder durch später im Betrieb einsetzende Verlagerung der Rohrleitung bzw. sonstiger dazugehöriger Teile.The sealing that is often inadequate when these slides are used is often caused by tension in the housing caused by gaping flanges that are tightly tightened during assembly or by later on in operation Relocation of the pipeline or other associated parts.

Zweck der vorliegenden Erfindung ist die Schaffung eines einfachen, billigen und gut abdich`= tenden Absperrschiebers. Dazu wird hiermit als neu die in folgendem gekennzeichnete Konstruktion zum Patent angemeldet.The purpose of the present invention is to create a simple, cheap and well-sealed gate valve. For this purpose, the Patent pending in the following design.

Die Absperrplatten i und 2 des Absperrschiebers auf Abb. i sind durch den metallenen biegsamen Anker 3 miteinander zu einem Dichtungskeil verbunden, welcher sich infolge der Elastizität seiner Verbindungskonstruktion gegebenenfalls einer veränderten Keilform der Gehäusesitzflächen anpaßt. Der Anker ist so schlank gehalten, wie es die übertragenden Druckkräfte mit Rücksicht auf seine Knickfestigkeit erlauben.The shut-off plates i and 2 of the gate valve in Fig. I are through the metal flexible armature 3 connected to one another to form a sealing wedge, which possibly due to the elasticity of its connecting structure adapted to changed wedge shape of the housing seat surfaces. The anchor is so slim as the transmitted compressive forces allow with regard to its buckling strength.

Bei Schiebern mit schiebender Spindel, also solcher mit Außengewinde, ruht die Hülse 4 zur Aufnahme des Spindelkopfes auf den zur Befestigung des Arikers erforderlichen Naben.In the case of valves with a sliding spindle, i.e. those with an external thread, the sleeve 4 for receiving the spindle head rests on the one for fastening the Ariker required hubs.

PATENTANSPRÜCHE: i. Keilschieber mit zwei .11)sperrplatten, dadurch gekennzeichnet, daß die beiden Platten durch einen metallenen, biegsamen und schlanken Anker miteinander fest verbunden und gegeneinander abgestutzt sind. PATENT CLAIMS: i. Wedge gate valve with two .11) locking plates, thereby characterized in that the two plates are made of metal, flexible and slender Anchors are firmly connected and braced against each other. 2. Keilschieber nach Anspruch i, dadurch gekennzeichnet, claß die Absperrplatten zur Befestigung des Ankers auf ihren Mitten Naben aufweisen, durch die der Schließdruck von der Spindel her in die Platten eingeleitet wird.2. Wedge valve according to claim i, characterized in that the shut-off plates are used for fastening of the armature have hubs on their centers, through which the closing pressure of the Spindle is introduced into the plates.
