Definitions
- the present invention relates to an anti-fraud hose connection in particular for water meters.
- the water meters 1 are generally mounted on the inlet piping 2 and the distribution piping 3 using two fittings 4, 5 each comprising a threaded ring 6 screwing on a hollow end piece 7 secured to the meter.
- the upstream connector 4 is most often installed directly at the outlet of a stop valve 8.
- These threaded rings have an external shape similar to that of a hexagonal nut, which allows them to be maneuvered with a simple open-end wrench or a common adjustable wrench.
- the device according to the present invention makes it possible, at a very cost, to make it much more difficult to deactivate the meter, not by making tamper-proof the disassembly of the connector on a water meter, but by making it impossible to reassemble for the fraudster , which forces the latter to call on the competent service for its return to service.
- Figure 1 shows the mounting of a water meter and its stopcock on a water supply pipe
- Figure 2 is an enlarged axial section of a connector according to the invention in screwed position
- Figure 3 is a partial axial section showing the same connector in the unscrewed position blocked by one split ring
- Figure 4 shows under the same conditions a variant in which the blocking takes place in the screwed position
- Figure 5 is a plan view of the split ring showing the waiting position in solid lines and the broken position in broken lines.
- the device consists of a threaded ring 6 sliding, during screwing or unscrewing, on a sleeve 9 connected to the shut-off valve 8 upstream and to the distribution piping 3 downstream.
- the ring 6 is provided with a circular internal groove 10 of substantially rectangular section, and the sleeve 9 with an external groove 11 of the same shape.
- the sheath groove receives a resilient split ring 12 of steel, also of rectangular section, which is held in place by means of a removable cylindrical sleeve 13 of thin steel (of the order of 0.1 mm) inserted between the sheath and the sleeve which will be removed after the final fitting of the fitting (figure 2).
- the split ring is chosen in such a way that it must be moved aside to be inserted in the groove of the ring 6, and that it tends to close when it is released.
- the axial location of the grooves 10 and 11 is determined so that they coincide in finding face to face when the sheath 6 is unscrewed ( Figure 3).
- the sleeve holds the split ring 12 in the groove of the sheath 6, which allows the latter to slide and therefore to be screwed onto the threaded end piece 7 of the counter.
- This operation finished the sleeve is removed, and the split ring rests on the external surface of the sleeve 9. If the ring is unscrewed, the sliding of the latter on the sleeve will cause the two grooves to coincide. As soon as this occurs, the split ring closes and its inner part enters the groove 11 of the sleeve.
- the width of the split ring is such that its outer part is always engaged in the groove of the threaded sheath 6. The latter and the sleeve are therefore secured, which prevents in future any screwing of the connection which will remain permanently blocked in the unscrewed position.
- a stop valve 8 comprising a sleeve 9 molded directly with the body so as to form a single piece with the latter, the threaded ring being crimped on this sleeve.
- the location of the grooves 10 and 11 can be chosen so that the blocking occurs when the connector is in the screwed position, which ensures locking of the assembly which can only be removed with special tools.
- This variant can give rise to multiple applications in numerous fields, whenever it is desired to prohibit the disassembly of a pipe fitting.
