Abstract

Arrangement in a coupling box for hydraulic fittings, which is mounted in association with hydraulic fittings 1 in buildings, the water pipes or heating pipes being mounted in protective conduits and the coupling of the hydraulic fitting 1 to the water pipe or heating pipe being carried out in said coupling box, and the coupling box being closed by means of a tension nut 6. In the coupling box 4, which by virtue of its construction is watertight, there is a leakage water duct 7, 9 for conducting leakage water through the tension nut 6 to outside the wall construction 5. <IMAGE>

ARRANGEMENT IN CONNECTION BOX

The invention relates to a junction box for use in connection with plumbing fixtures according to claim 1, which is otherwise watertight but comprises a duct for conducting leakage water in a controlled manner outside the wall structure in which the junction box is mounted.

A junction box is already known, which is made watertight e.g. Finnish patent 86321 and a junction box from which a leakage channel is led to a floor drain are known from patent 84743. A watertight junction box is cumbersome in that in the event of a leak, the entire water network pressure Thus, water damage can most likely occur to a portion of wall or floor structures.

When the leakage water is led from the junction box to the floor drain according to patent 84743 along the duct, the existence of a leak cannot be detected without special alarm devices. If there are no alarms, a small leak cannot be noticed without. open the cover of the junction box or inspection box or similar.

In order to avoid these drawbacks, a simple arrangement has been developed which is formed in a junction box and the arrangement "solves the problems of leak detection and damage to wall structures. The arrangement according to the invention is characterized by what is stated in the appended claims.

The most important advantage of the invention is that a leak in the water or heating network is detected immediately at the wall connection point of the furniture in question. Ve leakage is limited only to the outer surface of the wall and floor, which are usually a water-resistant coating in these plumbing spaces. The leakage water is directed so that it does not flow into the wall structure by leaving or directing the end of the leakage channel to the outer surface of the wall.

In the following, the invention will be explained in more detail with reference to the accompanying drawing, in which Figure 1 shows a plumbing fixture.

Figure 2 shows the junction box in the wall.

Figure 3 shows a tightening nut.

Figure 4 shows a leakage channel structure.

In Figure 1, a lever tap 1 is mounted on the wall and the cover cup 2 is covered with an opening in the wall and a junction box otherwise visible from the opening. There is a hole 3 at the bottom of the cover cup.

Figure 2 shows a wall-mounted junction box 4. The outer structure of the wall is a plate 5. A tap angle (not shown) is placed in the junction box 4. relative to the shell. The coupling box 4 thus becomes tight against leakage water towards the water supply. In the direction of the piping entering the box, the box is also watertight, with the piping protection pipe being sealed to the box protection pipe connection. As a result of a leak or rupture in the actual piping or its connections, the pressure in the water network enters the junction box and the protective pipe leading to the box, if the other end of the protective pipe is correspondingly tight. In the structure of Fig. 2, the pressure rise is limited in the event of a leak and the leak is allowed to take place inside the box 4 along the channel 7 on the surface of the wall plate 5. The channel 7 is formed in the clamping nut 6. The clamping nut has a cylindrical collar portion facing the water fixture and the cover cup, and this collar portion is generally cut flush with or slightly protruding from the surface of the wall. The duct part 7 is left as long as possible so that the leaking water flows into the surface of the wall plate 5. It is advantageous to remain as low as possible on the circumference of the tightening nut when tightening the chicken part 7.

Figure 3 shows an end view of the tightening nut 6 and the channel 7 is the only hole through the nut in the annular body of the nut.

In Fig. 4, the tightening nut 6 has only a small pipe connection 9 as an extension of the channel passing through the nut 6. A flexible hose 8 is inserted into the pipe connection 9, by means of which leakage water can be led to the wall surface in a controlled manner. The hole 3 in the cover cup 2 can advantageously be used as a guide for the end of the hose 8 by guiding the end of the hose slightly out of the hole 3. In this case, it is possible to completely ensure that leakage water only flows along the outer surface of the wall.

The invention is not limited to the appended embodiment, but many modifications are possible within the scope of the inventive idea defined by the appended claims.
