FI112689B - Angled tap case for connecting wall mounted taps to water pipes, has pipe connection screwed into cylindrical part of case which may contain sealing ring - Google Patents

Abstract

The pipe connection (2a) is threaded so that it can be screwed into a threaded cylindrical part (10) of the case (1). A sealing ring (3) is located between the pipe connection and case, either inside a cylindrical part (9) of the pipe connection or inside the cylindrical part of the case. The cylindrical surface of the ring has a different diameter to the thread inside the cylindrical part of the case.

HANA ANGLE BOX

The invention relates to an external shield for a pipe joint and to a Hook Angle Box for connecting the protective pipes of the pipelines leading to said Tube Joint 5, which includes a pipe connector for connecting a pipe protection pipe to the Hook Angle Box.

The tap box is commonly used in plumbing fixtures, where it is intended to serve as a wall-mounted sealed housing for the pipe connection when a cold or hot water pipe 10 or both is introduced into a wall mounted water point such as a faucet or double tap. The tap box has a pipe fitting towards the incoming pipeline, through which the pipe is routed for connection to the tap box. The pipe itself is fitted with a protective pipe installed to protect the incoming pipe. If the aforesaid assembly is integral with the body of the taper box, the incoming tube must pass through said rigid tube connector into the taper box 15 and further sharply bend 90 ° in the box and get the end of the tube out of the box to connect therein.

In order to alleviate the aforementioned inconvenient work, the present invention provides a new solution for a removable protective tube tube assembly, characterized in that the tube tube is threaded, said tube being rotatable in a tapered cylinder part or the cylindrical part in the tap-corner box and that the counter-face (cylindrical surface) of the ring seal has a different diameter than the counter-thread in the tap-corner box.

An advantage of the tapered corner box according to the invention is that the pipe fitting can be detached from the tapered corner box, whereby the incoming pipe, plastic or copper pipe, is easily pushed through the taped corner box despite the sharp bending. When the elbow is mounted at the end of the pipe and the elbow is planted in the Tap Corner Box, the pipe joint can be twisted in place and a protective pipe may be attached thereto. Due to the way the pipe joint is sealed and fastened, the pipe joint may twist open when installing the protective pipe and this will not cause any loss of sealing. Known pipe couplings with a seal must be screwed down to achieve the sealing effect. The pipe fitting according to the invention is sealed to the Tap Corner Box whether or not its thread is screwed to the end. When the pipe fitting is threaded and removable, different degrees of pipe fittings can also be selected to provide different inlet orientations for the incoming pipe. The use of such a pipe coupling for the protective pipe is possible because it is not necessary to rotate the pipe completely due to compression into the counter thread.

In the following, the invention will be explained in more detail with reference to the accompanying drawing, in which Figure 1 shows a side angled box with the tube assembly removed.

Fig. 2 shows a side angled box with the tube connector attached.

Figure 3 shows a tube assembly with a direction angle.

Figure 4 shows a double tap box and piping assembly.

Fig. 1 shows a tapered corner box 1 comprising a box known per se, with a metallic angular connector 12 disposed therein as a pipe fitting. The pipe connection 2a of the incoming protective tube 15 is loose and can be screwed into a thread 4 formed in the cylindrical part 10 of the body of the taper box. retraction when the corner connector 12 is attached to its end. The retraction takes place so that the corner connector 2 sits in place at box 20.

The pipe connection 2a is sealed to the body of the tapered corner box on the inner surface of the cylindrical part 10, into which the cylindrical part 9 provided with the seal 3 of the pipe connection 2a slides. Sealing is done in different diameters! . ' instead of the connecting thread 4.5. The seal 3 is located at the leading edge of the cylindrical part 9 so that it seals the joint as soon as it has slid into the cylindrical part 10. If the seal 3 was of the same diameter as the thread 5 according to the known installation method, it would have to be placed after the thread 5 and the joint would then have to be completed to seal. : would happen.

_ '! In Figure 2, the pipe connector 2a is threaded onto the body of a taper box and the seal 3 is slid on the inner surface of the cylindrical part 10. The incoming pipe 7 is connected to the corner connector 12 and the corner connector · · is installed. Finally, the protective tube 8 is mounted on top of one another 2a. The pipe connection 2a need not be screwed out, since the sealing works in the same way. Thus, in the installation of the protective tube 8, the tube connector 2a can also rotate in its thread.

The ring seal 3 may equally well be on the inner surface and preferably at the front edge of the cylindrical part 10 of the Tap Corner Box. This results in a corresponding sealing result without the need to rotate the thread 4.5 to achieve sealing. Also in this case, the diameter of the mating surface of the ring-5 seal, i.e. the outer surface of the cylindrical part 9, is different from the diameter of the thread 4.5.

Fig. 3 shows a pipe connection 2b with one direction at an angle α relative to the center line of the threads. When the pipe fitting 2 is a removable design according to the invention, the directional fitting 2b can be used as a pipe fitting, which can be used in this case when, due to the sealing method, the twisting 2b can be stopped when it has the desired direction. Thus, according to Figure 4, when using directional joints 2b, the incoming pipelines with the protective pipes 8, in the case of double angles, can be joined at a very short distance, e.g. In other cases, it may also be advantageous to use directional connectors from the box.
