DE3305526A1 - Remotely operated clamping connection device for two pipes or cylindrical containers - Google Patents

Abstract

In a remotely operated clamping connection device for two pipes or cylindrical containers having connecting flanges, which are installed for example in a high-temperature reactor, four clamping ring segments are provided, three of which are connected in a jointed manner by hinges. Fitted to two mutually abutting unconnected segments are clamping devices which can be clamped together tangentially with respect to the pipes by means of a clamping device described in the main application P 3133517.9. This allows the clamping ring segments to be pressed radially against the connecting flanges of the pipes. In order to be able to control precisely the movement sequence on closing and on opening of the clamping connecting device, a restraint is provided according to the invention, which consists of flaps with elongated holes and guide bolts. The flaps can be fitted to the device itself, to one of the pipes or to the wall of a duct in which the pipes are installed.

Remotely operated clamp connection device for two pipes or cylindrical containers

The invention relates to a remotely operable clamping connection device for two pipes or cylindrical vessels with connecting flanges, especially in a high temperature reactor with four profile clamping ring segments, from three of which are hinged together and two adjacent segments with clamping elements in Operational connection are - arranged by a remote-controlled, essentially axially parallel to the tubes and essentially effective in this direction clamping device can be actuated, whereby the clamping ring segments tangentially can be clamped together to form the pipes and hereby can be pressed radially against the connecting flanges of the pipes, according to FIG the patent application P 31 33 517.9

From DE-OS 2 452 770 a clamping connection device is known in which the hingedly connected Clamping ring segments from a clamping screw to- ■ clamped together and against the two container parts

or pressed against the pipes. The remote control the clamping screw can, however, only take place here at one of its ends and - which is particularly important - only with a clamping tool that acts or acts transversely to the axis of the container or the pipes. Inevitably this construction requires a relatively large amount of space around the container or the pipes in which they receive Tunnel / for example a prestressed concrete tank.

In the main application DE-OS P 31 33 517.9, the problem is solved, the remote control of clamping elements mit.Mittel zu that take up the smallest possible space and work reliably. For this purpose there is a jig provided, which can be operated axially parallel to the tubes or container parts.

The object of the present invention is that of the main application known clamping connection device to that effect; to improve - that the sequence of movements of the individual clamping ring segments is controlled upon actuation of the clamping device. .

According to the invention, this object is achieved in that for centering and spreading apart the clamping ring segments a positive guide is provided, the components of which are partly on the clamping connection device and partly on are attached to one of the two tubes and consist of guide pins and tabs with elongated holes, each with one another are engaged. ·

The forced guidance is with the highest reliability achieved the complete spreading apart of the clamping ring segments and the lifting of the device from the connection

flanges causes.

The tabs of the restraint can be on the circumference of one of the be attached to both tubes; in this case the guide pins are formed by extensions of the hinge pins, belonging to the hinges connecting the clamping ring segments.

Advantageously, the hinge pin is on the extensions one needle bearing each put on. Extensions and tabs are assigned to each other so that the needle bearings run in the elongated holes of the tabs.

To give the positive guidance more strength, each bracket can be supported on the tube by two struts.

It is also possible to release the tabs of the positive guidance on the Provide device and the guide pins, for example with the aid of a support piece placed on one of the tubes, to be attached to the tube. Two tabs are about diametrically attached to two clamping ring segments, and one The third tab is on the hinge between these two clamping ring segments.

If the remotely operated clamping connection device is included If two pipes are used, which are installed in a tunnel of a prestressed concrete tank, one Forced guidance can be provided from tabs and guide pins, with the option of using the tabs or to attach the guide bolts to the tunnel wall instead of one of the pipes.

In the drawing is an embodiment of the erfindurigs-

FIGS. 1 and 2 show a pipe 1 which is connected to a pipe 2 in a gas-tight and pressure-tight manner. On every pipe or 2, a flange 3 or 4 is welded, of which the flange 4 has an axial projection on its inner circumference has, whereby the tubes 1 and 2 more easily in a. bring the coaxial position. In the end face of the flange 4, an annular groove 6 is provided into which one Ring seal 7 is inserted. Both flanges have inclined flanks 8 and 9. '
