Socket connection with self-locking elastic Diohtung.

Hoof connections are already known, in which the seal is made by an outer ring, e.g. Sohrautmuffe * This type of seal has the disadvantage that the seal is only made by pressing

Sealing ring it is done by means of a screwed-in or screwed-on DruoXring and that when tightening the Qwmidiohtungsring is strongly guaranteed in most cases, apart from the fact that the production of the connection, the screwing in or unscrewing of the pressure parts to give the rubber ring the appropriate contact pressure, Takes up a relatively long time and it is also difficult to check whether the rubber ring has enough pressure "

Uani avoids these disadvantages according to the Innovation in that the elastic sealing ring is pushed into the sleeve and connected to it by a Pressure ring is held in the socket, the elastic sealing ring has, for example, a double-T-fb'mtgm Cross-section on. The connection of the known pressure

There are several exemplary embodiments in the drawing a socket connection according to the innovation in 15 figures shown,

Jfie from Ftg.l and 2 for example ersiohtlioh, becomes an elastic one in the space between the socket end α and tail end b of the nested pipes Ring, e.g. B. from Qurmi, ο pushed in and secured by an annular pressure piece el in the sleeve or, easily pressed on. The sealing ring has a double T-shaped Cross-section on, one forms, as shown, the opposite the end of the pressure ring that places the Dicfi Jungsring d nose or, wedge-shaped or semicircular, so you get, that the sealing ring evenly to both the tail end b and the socket end α and in the Qrund of The sleeve is slightly pressed on or in. Due to the specified design of the pressure ring d, between the pressure ring and the walls of the sleeve and the tail end des Rohi'es b wedge-shaped sealing chambers formed. As soon as the pipeline is pressurized, it takes effect the internal pressure due to the design of the sealing ring on this self-sealing, namely inside File similar to a cuff, in the wedge-shaped sealing chambers through the Qesamtdruok.

To be a close concern of the

Instead of the socket base in the specified fet se can also be a special ring g, as in Fig. 4 _t shows to be inserted.

The on or Press in the pressure ring d Hann with the help of printing devices h), which in Figs. 1, and 2, 5, 6 and 7 are achemattsch oeransoh'Aultoht. Use Druok or Pulling devices with screws, cables, levers or other elements. The Druakring d is in the example held in the position shown in Fig.2 and that through a pin hook i, which has a has a small recess H in which it was found of the pressure ring d as a result of the tension of the sealing ring ο inserts, so that the pin i can fall out prevents tst * The pin t can be fitted with a back plate 1 be provided, which is attached to the outer wall the sleeve inserts to the pin in setner perpendicular To hold position to the pipe axis.

Another way of connecting between Pressure ring and sleeve did the one shown in Fig, 2a, here a screw m is provided, which is in the pressure ring is screwed in, for this purpose by Umbö'rdeln of the end is reinforced.

While in the execution forms moh fXg.2 and 2a the fastening pin is obstructed by a hole in the socket, in the designs moh Fig 6,9 , Io and II the pins i are firmly connected to the pressure pipe. The connection with the The socket is given a bayonetto base »Duroh the so close arrangement of the exhaust η in the socket is caused that the pressure ring d the sealing ring ο gives a pretension in the direction of the bevels. As soon as the pin i has reached the end of the sinewy , this pretension is the Push it into the recessed recess on the side automatically, completing the connection.

The execution me Fig. 10 and 11 differs Όοη the after Fi <;. e and 9 in that the slot η does not extend to the end of the socket, but rather beforehand ends, so that the socket base ends in a context Ring forms. This is achieved through a funnel shape Expansion of the l / uffenendes o.

Instead of providing slots in the sleeve, you can also provide bulges or expressions and indentations ρ, then engage in the correspondingly designed cams α of the pressure ring, as can be seen from Fig. 12, 13, also here there is an interruption of the socket edge The number of attachment points is selected according to the existing pressure

Because the Schanz end of the Rohr4s only in one sctunalen, elastic ring is held, one can in the connection of FIG. 2, as shown in dotted lines is, place the corresponding kinks after y, whereby the Mw pivot point of the pipe is in the vicinity of χ, without the

In order to prevent individual pipes from falling out completely in the event of greater tensile stresses in the finished line the sleeve can be pulled out according to Ftg * l and the tail end of the tube b with a corresponding one Sioherung provided, e.g. with a flank on the right side of the Sioherung can be trained in the well-known quiet bayonet style aa.
