BE1024964B1 - RAPID SHUTTER DEVICE FOR SUPPRESSING A CONNECTION - Google Patents

Abstract

Quick shut-off device following the suppression for any reason of the connection between the gas supply pipe and the pipe intended for use in order to avoid as much as possible the danger of gas leakage following this removal. This device consists of a dome provided with a flexible fire-resistant seal and is welded to the supply tube and thus covers the end of pipe resulting from the removal of the connection. This dome is covered with a plate of identical shape to the shape of the supplier pipe and which has an opening for the passage of the dome and is also welded to the main pipe thus reinforcing the shutter.

BE2017 / 0045

The removal, for any reason, of a connection between the main gas supply pipe by the responsible firm holding the product and the supply pipe to the user is carried out by disconnecting the connection pipe and then by welding a shutter system. The generally used welding system is an arc system.

Note, however, that all the material intended for this work (tubes, welder, connection sleeves) must also meet very strict requirements.

The big problem which is posed is that following the removal of the supply pipe to the user there remains a piece of pipe therefore an opening towards the main duct and consequently an obvious risk of gas leakage and a danger for the worker doing the work.

The device currently used consists in welding a plate of determined length and having an inside diameter equal to the outside diameter of the main pipe this in order to cover the opening made but this work being carried out on a pipe in use, therefore under pressure, requires a certain period of time and the danger following this gas leak persists during this time.

The device described below overcomes this danger.

This device also consists in welding the same kind of plate but this one has a central hole of adequate diameter and which allows the passage of a dome having a convex bottom identical to the external shape of the main pipe and applying to the opening of the user hose. In addition, to increase the tightness of the system, this dome carries a flexible, fire-resistant membrane glued to its base.

The figures below show the composition of the claimed device:

Figure 1 shows the system after removal of connection 2. This figure shows the opening 3 created by this removal and which poses a problem following the resulting gas leak and thus the danger of intoxication, of the operator.

Figure 2 shows the complete device claimed as used, namely:

the main pipe 1 and the sealing device 4 which rests at its base 6 on a flexible gasket 7 resistant to fire and a plate 8 of conventional type but having a hole 9 allowing the passage of the dome 5 and which is applied to said base 6 of said dome 5 and thus makes it possible to apply this device to the opening 3 and thus to completely seal the opening from which the gas leak comes.

FIG. 3 shows the composition of this device 4, namely:

a dome 5 whose base 6 provided with a seal 7 is applied to the main pipe 1 and has a diameter equal to the outside diameter of the main pipe 1.

FIG. 4 shows how to hold the assembly so that the device can be easily welded, namely:

a system 10 with screws 11 and which, thanks to a chain 12 placed around the tube 1, allows the assembly to be firmly held by tightening the screw 1 i.

Claims (6)

Claims 1. Quick shutter device when ia deletion of a connection between the main pipe 1 gas supplier and the user pipe 2 characterized in that it is under a dome 5 covering the end of sheared tube 2 . 2. Quick shutter device according to claim 1 characterized in that this dome 5 carries at its base 6 a flexible gasket 7 fire resistant to increase the tightness of the system. 3. Quick shutter device according to the preceding claims, characterized in that this dome 5 is welded to the main supplier tube 1. 4. Quick shutter device according to previous claims characterized in that this seal is covered with a plate 8 of internal shape similar to ia outside shape of the main tube. 5. Quick shutter device according to the preceding claims characterized in that this plate 8 has a central opening allowing 9 1st passage of the dome 5 on which it presses to secure even more firmly the shutter of the system. 6. Quick obturation device according to the preceding claims, characterized in that this plate 8 is also welded to the main tube 1 BE2017 / 0045 BE2017 / 0045 Pi BE2017 / 0045 Abridged Quick closing device after removal for any reason of the connection between the gas supply pipe and the pipe intended for use in order to 5 to minimize the danger of gas leakage following this deletion. This device consists of a dome provided with a flexible fire-resistant seal and is welded to the supplier tube and thus covers the end of pipe resulting from the removal of the connector. This dome is covered with a plate identical in shape to the shape of the supplier pipe 10 and which has an opening allowing the passage of the dome and is also welded to the main pipe, thereby reinforcing the sealing.
