Gegenstand der vorliegenden Erfindung ist eine weitere Ausbildung der Hilfsabsperrvorrichtung nach der Hauptpatentanmeldung; sie findet ihr Kennzeichen darin, daß in dem angeschraubten Gehäuse der Hilfsabsperrvorrichtung zwei Kolben angeordnet sind, von welchen der eine Kolben mit der von außen, her betätigbaren Spindel od. dgl. verbunden ist, während der andere Kolben den Zapfen mit der Gummiblase trägt und synchron mit dem ersteren Kolben bewegt wird, wobei das Druckmittel im Gehäuse zwischen dien Kolben vorgesehen und durch eine Durchbrechung des den Zapfen tragenden Kolbens in den hohlen Zapfen einführbar ist, um die ihn umgebende Blase aufzublähen. Es empfiehlt sich, die beiden Kolben durch eine Kette, und zwar beispielsweise durch eine Laschenkette, miteinander zu verbinden. Diese Kette ermöglicht zwar eine gegenseitige Annäherung der beiden Kolben, wenn ein Aufblähen der Gummiblase erfolgen soll. Sie sichert aber auch vor allen, Dingen eine Mitnahme des den Zapfen tragenden Kolbens bei der Rückbewegung des durch die. Spindel betätigten Arbeitskolbens.The present invention is a further embodiment of the auxiliary shut-off device according to the main patent application; it is characterized by the fact that in the screwed-on housing of the auxiliary shut-off device two pistons are arranged, of which one piston od with the externally actuatable spindle. The like. Is connected, while the other piston carries the pin with the rubber bladder and moves synchronously with the first piston is, wherein the pressure medium is provided in the housing between the piston and through an opening of the the piston carrying the pin can be inserted into the hollow pin in order to inflate the bladder surrounding it. It is advisable to chain the two pistons, for example by a Link chain to connect with each other. This chain allows a mutual approximation of the two pistons when there is an inflation of the rubber bladder should take place. But above all, it ensures that the piston carrying the pin is carried along the return movement of the. Spindle actuated working piston.

13 das Gehäuse 14 angeschraubt, in welchem die beiden Kolben 15 und 16 geführt sind. Der Kolben 15 trägt einen. Zapfen 17, der von der Gummiblase 18 umgeben ist. Außerdem weist der Kolben 15 eine Durchbrechung 19 auf, durch welche das Druckmittel aus dem Raum 20 in den Zapfen eintreten kann, wenn die Gummiblase 18 aufgebläht werden soll. Der Kolben 16 steht mit der Betätigungsspindel 21 in Verbindung und kann durch diese in dem Gehäuse 14 hin- und herbewegt werden. Der Raum 20 zwischen den beiden Kolben 15 und 16 ist mit einen, hydraulischen Druckmittel gefüllt. Dieses bewirkt im allgemeinen eine synchrone Bewegung des Kolbens 15 bei der Verschiebung des Kolbens 16 in der einen oder anderen Richtung. Vorsorglich, ist eine zusätzliche Verbindung zwischen diesen beiden Kolben durch, die Laschenkette 22 geschaffen.13 screwed on the housing 14 in which the two pistons 15 and 16 are guided. The piston 15 carries a. Pin 17, which is surrounded by the rubber bladder 18. In addition, the piston 15 has a Opening 19 through which the pressure medium can enter from the space 20 in the pin, if the rubber bladder 18 is to be inflated. The piston 16 is with the actuating spindle 21 in Connection and can be moved back and forth through this in the housing 14. The space 20 between the two pistons 15 and 16 is one hydraulic Pressure medium filled. This causes a synchronous movement of the piston 15 in general the displacement of the piston 16 in one direction or the other. As a precaution, is an additional one Connection between these two pistons through the link chain 22 created.

Nachdem das Gehäuse 10 des Anbohrventils an, das die Transpoirtfaitung umgebende Schellenband angeschraubt und die Hilfsvorrichtung angebaut ist, befinden, sich die Teile zunächst in der in Fig. 1 skizzierten Lage. Bei dieser Stellung der Teile wird das Anbohrgerät auf den Ventilstutzen 12 aufgeschraubt und durch die axiale Durchflußöffnung des Gehäuses 10 hindurch dia Transportleitung angebohrt. Ist das geschehen1, so wird das Bohrgerät bis in den Stutzen 12 zurückgeschraubt, und, anschließend tritt die Hilfsabsperrvorrichtung in Tätigkeit. Durch Drehen der Spindel 21 wird der Kolben 16 und über das den Raum 20 füllende Druckmittel auch der Kalben 15 entsprechend vorgeschoben, bis der Zapfen 17 mit der Gummiblase 18 die in Fig. 2 skizzierte Lage einnehmen. Erfolgt dann eine weitere DrehungAfter the housing 10 of the tapping valve is attached to the clamp band surrounding the transport connection and the auxiliary device is attached, the parts are initially in the position shown in FIG. 1. With the parts in this position, the tapping device is screwed onto the valve connector 12 and drilled through the axial flow opening of the housing 10 through the transport line. Once this has happened 1 , the drill is screwed back into the socket 12, and then the auxiliary shut-off device comes into operation. By rotating the spindle 21, the piston 16 and, via the pressure medium filling the space 20, also the calves 15 are advanced accordingly until the pin 17 with the rubber bladder 18 assume the position sketched in FIG. Then there is another rotation

der Spindel 21 in gleicher Richtung, so> kann der Kolben 15 nicht mehr weiter vorgeschoben werden, da der Zapfen 17 an der Wand der axialen Durchflußöffnung aufsitzt. Eine weitere Vorwärtsbewegung· des Kolbens 16 bewirkt sodann eine Druckerhöhung des Druckmittels in dem Ra,um 20. Die Druckerhöhung pflanzt sich durch die Durchbrechung 19 und den Kanal des Zapfens 17 fort bis in die Gummiblase, und diese wird daher, wie bei 18 in Fig. 3 punktiert angedeutet, so aufgebläht, daß sie den axialen. Durchgang des Ventilgehäuses 10 vollkommen dicht verschließt. Ist das erreicht, so kann das Anbohrgerät entfernt und durch das Ventiloberteil 23 ersetzt werden.. Sobald dieses das Ventilgehäuse 10 nach oben hin eindeutig verschließt, wird durch Drehen der Ventilspindel 21 in entgegengesetzter Richtung der Kolben 16 zurückgeschraubt mit der Wirkung, daß zunächst die Druckflüssigkeit in dem Raum 20 entlastet wird. Dadurch wird die Aufblähung der Gummiblase 18 rückgängig gemacht, wie in Fig. 4 erkennbar ist.the spindle 21 in the same direction, so> the piston 15 can no longer be advanced because the pin 17 is on the wall of the axial flow opening sits on. A further forward movement of the piston 16 then increases the pressure of the pressure medium in the Ra, at 20. The pressure increase is planted through the opening 19 and the channel of the Pin 17 continues into the rubber bladder, and this is therefore indicated by dotted lines at 18 in FIG. 3, so inflated that it is the axial. Passage of the valve housing 10 closes completely tight. is achieved this, the tapping device can be removed and replaced by the valve upper part 23 .. As soon as this clearly closes the valve housing 10 towards the top is activated by turning the valve spindle 21 in the opposite direction, the piston 16 is screwed back with the effect that first the pressure fluid in the room 20 is relieved. This reverses the inflation of the rubber bladder 18 made, as can be seen in FIG.
