Connector for pipe wall entries, comprising a wall panel and a clamping connection

TECHNICAL FIELD

The present invention relates to a connection device for pipe wall penetrations, in particular a pipe for a water distribution system, said device comprising a clamping sleeve joint and wall plate, wherein the clamping joint comprises a first coupling part protruding from the wall panel and a second connecting member. with.

BACKGROUND AND PROBLEM

15 Wall plates having clamping sleeve joints of a known type are used to pass and connect pipes, in particular water distribution pipes, through the wall, for example in the case of taps and radiators in bathrooms or other spaces. For example, in a detached house, water distribution pipes are drawn into a room, such as a bathroom, where water will be used.

• · • ··. The water is then led, for example, to the wash basin mixed or similar, and to the wall; plates with clamping sleeve joints are used for this transition at concealed pipe joints on the wall ♦ and visible pipe outlets ····. **. between the joints. This is to ensure that the pipes in the wall are neatly and reliably connected to the pipes in the room, because for practical and aesthetic reasons, these pipes are rarely of the same type. The pipes in the wall are often made of copper or plastic, and the pipes in the room are. *: ·. often made of steel or chromed copper.

• · m · «· * ··. ···. In general, the device of the above may be described as a wall plate which is normally fixed to a first connection part, such as a nut, which is riveted or pierced by an opening made through the plate for this purpose. This nut and plate is mounted in a tube in the wall, usually 20-30 mm from the wall and fixed to the wall with a sealing kit or bracket. A clamping sleeve of known type is then fitted to the end of the pipe 5, as well as another connecting part, such as a connecting pipe, a wall valve or an angled pipe, which is arranged to be screwed onto the first connecting part in known manner. The first and second connection portions are usually provided with internal conical surfaces which cause deformation of the clamping sleeve on the tube because the second connection portion is screwed onto the first connection portion 10, which allows the tube to be sealed to the connection.

However, commonly available wall panels having a clamping sleeve joint are susceptible to a number of problems, with the major problem being the need to disassemble the panel. It is often necessary to dismantle the wall panel during major repairs or replacement of wall panels, such as a damp ti-15 floor mat to a tile wall. In addition, reinstallation may be necessary due to incorrect installation of the wall panel. Many existing wall panels are equipped with a flow detector which, in the event of a leak, allows water to drip out of the front of the wall through the drainage opening in the wall panel and thus become visible inside it. 20, so that it builds up inside the wall, where it cannot be detected, and can lead to • · (i.v. a routine water damage before final detection.) Drainage openings, ♦ · which are connected to the connector ducts and continue in the sealing layer. . ** ·. Behind the vinyl is often tracked only at one end of the plate, so the installer · «« has to be very careful to ensure that the plate is oriented so that the water ··· 25 outlet is towards the floor. and flows into the wall ····: ***: in the event of a leak, which means that it is necessary to disassemble the board if the installer has turned the board upside down. therefore, there is a problem associated with it because it depends on how the disk is flipped.

• · • · · 30 • · 3 119157

Unfortunately, dismantling existing wall panels is easier said than done. Of course, once the clamping sleeve has been deformed on the pipe, the nut can no longer be re-routed in the same way, and thus the wall panel cannot be disassembled with less than removing the Kiris-5 sleeve, or alternatively the pipe may be severed inside the clamping sleeve. cutting off the end of the pipe to which the sleeve was attached. However, none of these methods are preferred. In the first case, the clamping sleeve is pulled out of the pipe by some kind of tool, and since the sleeve is very tightly fitted to the pipe, 10 deformations have occurred in the pipe, mainly in the form of longitudinal scratches. These scratches reduce the sealing properties of the joint and can lead to leakage when a new clamping sleeve is then attached and the joint is reinstalled. In the second case, the tube remains intact (because the joint is in a "new" part of the tube), but in many cases this method is not at all practicable because the tube projecting from the wall is too short to be cut and then held inside the new joint.

In addition, in most cases, it is desirable to temporarily close the pipe for major repairs or replacement of, for example, wall panels, because it is not desirable to cut off the water • 20 because such an operation would cause disturbance to humans, particularly may apply to an entire house or multiple apartments.

• ·, ·, The closure is performed with the same type of clamping bushing that • · ·. ** ·. in turn, once the work is completed, it must be dismantled - resulting in the aforementioned • «* problem. A similar sealing operation must be carried out on new construction sites where the system must be pressure tested by water or air before official regulations, such as washbasin mixers and heating pads. *: *. the blades can be connected and finished.

In order to solve the above problem, where the clamping bushings have to be removed or alternatively pulled out by tools, a connector rail has been proposed. • «4 119157 with clamping sleeve split. The clamping sleeve can then be disassembled by carefully twisting it off with a tool. Unfortunately, then, a joint structure is achieved in which the function of the clamping sleeve is reduced to hold the pipe inside the joint and in which a seal which is at least as important for the operation of the joint must be provided with a standard sealing ring. This is undesirable since it is well known that sealing rings of the conventional type tend to age, whereby the sealing effect is correspondingly reduced. In addition, the sealing rings may harden and are difficult to adjust to the movements of the joint during temperature fluctuations and vibrations. A clamping sleeve with a sealing ring 10 also poses a risk of incorrect installation because it is very important that the clamping sleeve is twisted so that the sealing ring is aligned in the right direction. In addition, a split clamping sleeve will also damage the pipe, resulting in a risk of reinstallation.

Swedish patent publication SE 462 504 describes a known wall plate with connecting nuts. Each connecting nut thus has a flange smaller than the other portion of the connecting nut, said flange being adapted to pass through an opening in the wall plate when the connecting nut is installed. The connecting nut is then secured to the wall panel by moving the locking member, which is in the form of a brass ring, over the flanges 20 and into a groove in the flange behind the wall panel, radially inside. through a plastic deformation in the weather. After installation, • · ... the union nut can no longer be disassembled from the wall panel, thus causing the disassembly problem ··· *. ···. maintained.

In addition, many structures are designed solely to be connected to the first-connection fittings and not to the standard clamping fittings available on the market and commonly used in visible pipe fittings. These disassembly structures also require the use of special tools for installation and disassembly, which is undesirable for the installer, for example, or perhaps primarily for the kayaker, who in many cases must be equipped with numerous special tools and special interface components to maintain any type of wall.

SUMMARY OF THE INVENTION

As described above, the prior art wall-to-wall couplings for pipes, particularly water distribution system pipes, suffer from a number of problems, and it is therefore an object of the present invention to solve these problems by providing a device that allows the wall plate to be disassembled without damaging the pipe. that is, without having to remove the clamping sleeve or cut the pipe in order to get rid of the clamping sleeve * '*: · *; ·· • · '' 20 - which may allow the connection to be sealed by the existing first connection part so that the water distribution • system can be pressure tested after installation and may be in place during repairs or wall panel replacement; · - which gives reliable leak detection no matter how the wall panel was twisted during installation; «··· · ** · - provides very simple installation and disassembly that does not

DESCRIPTION OF AN EMBODIMENT

The invention relates to a wall-to-wall outlet connection for pipes, in particular water distribution), said device being of the type which includes a known clamping sleeve joint and wall plate. As described above, the device is particularly suitable for water supply system pipes, which water supply system may be located, for example, in a private home or in any other type of building. As explained above, the term wall penetration usually refers to a lead-through, or pipe joint, often between a hidden pipe extension inside a wall and a pipe extension often visible outside the wall.

The previously known clamping sleeve joint is used in the lead-through together with the wall plate as described above. The function of a wall panel is generally known per se, usually involving the installation of a joint and the covering of the pipe passage, whereby said covering performs two functions: partly to provide a good appearance and partly to prevent, for example, water penetration into the wall. The latter function is important, especially in humid rooms, where water is often sprayed on the walls in connection with showers and cleaning • · ·!; ·· *. The function of the clamping sleeve joint, also known in the prior art, is to hold the Φ · * "20 pipes protruding from the wall and provide a sealed joint.

• · • «

There are many types of clamping bushings, only one of which will be shown soon. but it will be understood that the invention is applicable to all other types of clamping sleeve connections. Thus, the connection as such is not described in great detail. In addition, many different types of wall panels • f · «; ** '· are known in the art, for example, in different sizes, and with respect to the various pipe numbers * φ ·, ···, and different types of washers. These, too, are not explained in great detail. Finally, it should be understood that there are various variations on how to protect pipes in the wall by means of protective pipes, etc., and this is only briefly explained with reference to embodiments.

The invention will now be described, with reference to Figures 1-4, by means of a preferred embodiment, where the device is used for the conventional wall passage of so-called PEX pipes in a wall.

In the drawings, reference numeral 10 indicates a wall plate known per se. The wall plate 10 of the type used for the passage and connection of the two tubes 12 and consisting of a thin substantially rectangular plate made of, for example, stainless steel, the front side of which is called its first side 14 and its rear side is called its outer rim a parallel edge which runs continuously in the direction toward one side 16 and is shaped to form a gap between the plate 10 and the wall 18 when the other side 16 of the plate 10 is held against the wall 18. This gap is filled in a known manner with the aid of a washer 20, which usually 15 consists of a cellular plastic sheet, for example a cellular polyethylene sheet. The washer 20 is shown, for example, in Figure 2. In addition, the wall plate 10 is provided with recesses for the screws by means of which the wall plate 10 is fastened to the wall. In the example shown, the wall plate 10 is also provided with two substantially circular openings 22 located at the passageway of the pipes. In an alternative embodiment not shown, the openings 22 may take other forms than circular, such as, for example, square, rectangular or polygonal, so that the first connection part, indicated by reference numeral 24, is provided in each of the respective openings 22 for the connection of corresponding pipes protruding from the wall 18. At least one the diameter of the opening 22 exceeds the diameter 25 of the first connection portion 22 so that a gap is formed between the opening 22 and the first connection portion 24. In this way, the gap is intended to make the connection portion 24 somewhat movable. »T si in aperture 22 to compensate for any fitting errors that may occur, t · ·. ··· if the apertures The distance between the 22 is not compatible with the distances of the tubes 12 (which tubes are fixed to the wall 18 in a known manner by a sealing bracket or fastener). 30 kee). The diameter of the orifice 22 is preferably 1 mm larger than the diameter of the connection portion 24 of the connection portion 24 passing through the orifice 22. This results in an overall tolerance of +/- 2 mm if both openings 22 have a larger diameter.

In the example, the pipes 12 are shown arranged in a vertical row, and the wall plate 10 is arranged accordingly, although it should be noted that the wall plate 10 can also be used in an installation where the pipes 12 are arranged in a horizontal row.

As mentioned above, the device also includes a first connection portion 24, as shown in Figures 1 and 3, said first connection portion 24 being tracked to protrude from the wall plate 10 in the installed state and also forming part of a known clamping connection. The clamping sleeve connection further includes a second coupling member (not shown) adapted to cooperate with the first coupling member and the first clamping sleeve (not shown). The Kiris-15 socket connection may be briefly described by saying that the first connection portion 24 is provided with an internal thread 26 (which will be explained in more detail below) and an internal conical surface 28. The second connection portion, which may consist of. for example, a connecting tube, a ball valve, or an angled tube, can be screwed to the first connection portion 24 and is thus provided with a thread corresponding to the thread 26 in the first connection portion. The second connection portion is also · · provided with a tapered surface. When screwing the second connection part into the first • ·.:. the conical surface in each member acts in a known manner together with the joint • Ml ***. with the surface of the outer circumference of the sleeve, thereby compressing the ring sufficiently firmly against the tube 12 such that the ring engages the tube 12 and slightly deforms the tube *: * 25.

···· • · · • · • «• · ·; |. The section of the first connecting part 24, which in the example consists of a nut, is substantially circular in section, and is divided into at least three parts I, M ·, ···. Π, ΙΠ in the direction of its axial extension as shown in Figures 1 and 3 in Roman numerals • ♦ ··· 30. In alternative non-disclosed embodiments, the first connecting member 24 may also have cross-sections other than circular, such as square or other polygonal cross-sections. The first part I consists of a flange 30 extending radially slightly outside the other two parts Π, ΓΠ. The next part, the second part Π, forms a radial groove 32, 5 whereby the first part I, i.e. the flange 30, forms the first axial end of the groove 32 and the third part ΠΙ forms the second axial end of the groove 32. The third portion HI thus has a larger cross-sectional dimension than the second portion Π, but small enough to allow the opening 32 in the wall plate 10 to be pulled over the third portion ensimmäisen of the first connection portion 24. At a distance of pie-10 from the end of the groove 32, the outer peripheral surface of the third portion is provided with a tool interface 34, for example a hexagonal or similar known interface for a wrench or other tool key. No special tools are required for installation or disassembly.

The flange 30 is provided with at least one protuberance 36, and preferably a plurality of protrusions 36, which cause the radial surfaces of the flange 30 to be non-planar but may instead be more or less wavy with the protrusions. depending on the amount. In the example, the flange 30 is provided with four protrusions 36, evenly distributed over the flange 30, see Figures 2 and 3. However, it should be noted that this may not be the most appropriate number in all structures. The operation of the coils ♦ .... · houms 36 will be explained later, and it will also become clear that the installation will be facilitated if a certain number of protrusions 36 are evenly distributed over the flange 30.

Unlike previously known wall panels having clamping sleeve connections, in the present invention, the first connection portion 24 is separate from the wall panel 10 and not fixedly connected to the wall panel 10. However, it is adapted to be fixed to the wall plate 10 by means of a locking member 31.

How this will be done will be explained in detail later. In the following, the locking member 38 in the preferred embodiment will first be described.

The purpose of the locking member 38 is to attach the first connecting part 24 to the wall 10 of the wall 10 and its shape thus depends on the shape of these parts. In the example, the locking member 38 is preferably formed as a locking ring, and this ring 38 is shown, for example, in Figures 4a-4c. The locking ring 38 is preferably provided with a radial slit 40. Further, the radial sides of the ring 38 have a parallel-conical shape such that when viewed in cross-section 15 of the ring 38, it can be seen that it is substantially parallel-shaped, see Figure 1. has a concave surface 42 and a convex surface 44.

According to Figures 4a-4c, the slit 40 is preferably chamfered, and the chamfer 46 is made ♦ · · • · «. '' The concave surfaces 42 of the ring 3 8 and the opposing surfaces of the slit 40 are formed by · ·

• M

', 20 to the edge between the respective surfaces. The bevel 46 thus extends between the outer circumference of the ring 38 and its inner periphery, and the radial cross-section of the slit 40 has a V-shape 48, whereby the opening in the V-shape 48 is thus directed to the ring 38 ··· *. * * *. towards the concave surface 42.

The material of the locking ring 38 should be flexible and preferably of, for example, a polymeric material type or a stainless spring material. In addition, the locking ring 38 should preferably be made with low bias, so that the locking ring ***, when unassembled, i.e. in an unloaded condition, reduces

Ml · * ·, by allowing the free ends to overlap at the slits 40, • · * · 30 see Figure 4b. When mounted, the diameter of the ring 38 should be such that the ends of the slit 40 meet and thus close the tip of the V-shape 48, see Figure 4a.

The installation and subsequent disassembly of the present invention will be explained in detail in the following.

The pipes 12, which are normally allowed to project about 120-30 m from the wall 18, depending on the choice of joint, are secured to the outer panel of the wall 18, which may be made of gypsum board, fixture or sealant (not shown) at a distance substantially 10. The tubes 12 inside the wall 18 may be covered by a known flexible protective tube 50 provided at the wall 18 with a known protective tube mounting sleeve 52. These parts are shown in Figure 1.

15 Only one tube 12 will be described below, but it should be noted that two locking rings 27 are used to pass the two tubes to the first connection portions 24.

The first connection portion 24, with flange 30 facing the wall 18, is secured to the tubes 12. Then it is time to attach the locking sleeve (not shown). In the case of a new installer, it may be possible to choose between screwing on the other connection part and completing the connection, then closing the free end of the second connection part and leaving it. Once this is done, a system pressure test can be performed, i.e. released. ** ·. water to flow for a short period of time to see that everything is in order before * * · proceeds to connect the taps and radiators. Thus, this is the principle of keeping the water and • toy system active during work, for example in the bathroom: when water is to be connected to other parts of the building. Pressure testing and 4 closing are temporary measures and do not need to be performed on the other · *** · part that is being used. There is no need to perform pressure testing and sealing

• M

, ···, for example, with the T-tube 1, which is then sought to be used for final fitting, · · ··· ,,, .: 30 but the connecting tube or the like can be used advantageously.

• 4,119,157 13

After pressure testing, or when the repair work has been completed, that is, when the installation is complete, the temporary second connector member is removed and it is time to install the wall board 10, or alternatively the selected second connector member used in the future depending on whether the wall board 10 over this or not. If, for example, a T-pipe is used as the second connection part, the wall plate 10 must first be installed. The same applies in the case where no pressure testing or sealing has been carried out or if the shape of the locking sleeve has not yet changed on the pipe 12.

The other side 16 of the wall plate 10, the backside facing the wall 18, is provided with a known type of washer 20 by means of an adhesive or other binder. There are, of course, two openings in the base plate 20 which correspond to the openings 22 in the plate 10. However, these openings must be larger than the openings in the plate 10, namely equal to or larger than the diameter of the flange 30 in the connecting portion 15.

The wall plate 10 is then passed over a possible second connection portion and then over the third portion of the first connection portion 24, i.e., the tool interface surface 34, and is placed in a second portion, i.e. a groove 32. The flange 30 then contacts the wall plate 10; 20 other sides 16.

Then the wall plate 10 is fastened with screws to the wall 18 and the time comes to fix it. the first connection part 24 to the wall plate 10 is provided by the locking means 3 8.

The locking ring 38 is expanded and passed over the first connection portion 24 so that the concave side 42 of the locking portion 38 is also against the first side 14 of the wall plate 10 and then released into the groove forming the second portion thereof. 32. Locking- · ***. the unidirectional conical shape of the ring 38 means that the inner circumference of the locking ring 38 contacts one end of the groove 32 in the first connection portion 24 and that the outer circumference of the locking ring 38 contacts the first side 14 of the wall plate 10. performing both axial and radial biasing of the first connection portion 24 against the wall plate 10, which results in good sealing against a jet of water, i.e. water sprayed onto the device, and which holds the locking ring 38 and the connection portion 24 in relation to each other. Once in place, ring 38 5 is rotated so that slot 40 is positioned in the direction toward the floor. This is due to a leak detection on the device and will be explained below.

After the connection portion 24 is secured to the wall plate 10, the second connection portion 10 is finally screwed (if not already in place). The second connection part can then be fitted with a pipe which is led outside the wall to, for example, a radiator or washbasin.

In the case of new installations, the wall plate 10 and its washer 20, the locking ring 38 and the first connection part 24 of the locking ring are not normally desired as parts. The installation of these components as a unit can then advantageously be done at the factory so that installation at the end user can be accelerated.

The main advantage of the invention, as explained above, is the ease of dismantling, which allows the wall outlet to be dismantled without damaging the pipe 12, i.e. without having to removes the locking sleeve from tube 12 with or without tube 12 • ·. ·. would need to be cut to get rid of the locking sleeves As mentioned, there are a number of cases where you need to be able to disassemble the wall plate ·· · and / or connection: when punching and replacing wall panels, pressure testing ··· 25 and closing to keep the water distribution system operational during long work periods.

In the practice of the present invention, installation is very simple, because the wall plate 10 can be passed over the first connection portion 22 and thus the locking sleeve * · 30 is not damaged.

• · 15 119157

More specifically, the disassembly is performed by unscrewing the second connection portion from the first connection portion 24 so that the tube end 12 and the locking sleeve (not shown) are exposed. The split locking ring 38 is then unscrewed with an exemplary screwdriver and disengaged from the first connection portion 24. The first connection portion 24 is then no longer secured to the wall plate 10 and since the opening 22 in the wall plate 10 is larger than the portions of the first connection portion 24 over to remove it, the wall plate 10 can be unscrewed from the wall 18 and passed past the first connection portion 24, which then remains on top of the tube 12 together with the locking sleeve (not shown).

If the job is designed to last for a long time and if the water supply rigid system is to operate during this time, the second connector (not shown) is screwed onto the first connector 24 with a plug. It is then simple to remove again when it is time to reinstall the system again in place.

Finally, it describes how the device, due to its design, provides reliable leak detection • · · # ** · *. If there is a leak in the joint or if the pipe on wall 18 has • • * «· t *. When something has happened, the water must be able to drain in front of the wall 18, so that the residents of the building are aware that something is wrong. This is accomplished by: • ♦ suitably provided with a drainage duct running through the back of the wall panel 10 ··· · ···. side 16 and outwards. However, when designing a drainage duct, the problem is ··· * that - while water must be able to find its way through the wall plate ··· 25 10 - the water must be prevented from entering the wall plate 10 during external showering.

«· * ··« • · · • · ·. * · *. The device of the present invention solves this problem. As explained above, the flange 30 is provided with at least one protrusion 36, and in the example • · iti]; The four protrusions 36 are equally spaced about the flange 30. Each protuberance 36 is shaped to form a radial passageway 54 together with the wall panel 10 when the flange 30 contacts the wall panel 10, said passage 54 extending substantially over the entire radius region of the flange 30 and thus communicating with the opening 22 of the wall panel 10. Since the opening 22 is larger than the circumference of the first connection portion 24, water may flow through the hole 22 into the groove in the first connection portion 24. Thus, water may flow from the inside of the wall plate 10 through the formed between the flange 30 and the wall plate 10 and exit to the front of the wall plate 10 into the groove 32 in which the locking ring 38 is inserted. It should be noted, therefore, that a plurality of protrusions 36 in the flange 30, evenly spaced around it, is preferred to a single protrusion 10, since the water is then very likely to find the channel 54, no matter how it flows.

As mentioned above, water flows into the groove 32 in which the conical locking ring 38 is located. The locking ring 38 delimits a substantially triangular region of cross-section, see Figure 1, which forms a radial and tangential dewatering slot 56. The water then flows into the slot 56 into a slot 40 which is preferably directed toward the floor, allowing it to drain out of the wall panel 10. front 14 where it appears. This construction effectively prevents water sprayed on the front of the wall panel 10 from entering the wall panel 10 because of the 40 of the locking ring 38 on the convex side 44, i.e., toward the room. on the side is closed. In addition, ring 38 is tightly biased both radially and axially so that the only point from which water could potentially enter is · · · in the radial bevel 46 if the gap 40 is preferably · · · placed in the ceiling in the direction of. However, this erroneous installation * 25 method can easily be disassembled by rotating the locking ring 38, which does not cause any damage to the first connection part 24 or the wall plate 10.

It should be noted that the invention is not limited to the embodiment shown, but that • φ φ, ···. several modifications, variations and modifications are contemplated within the scope of the appended claims. For example, the first connection portion 24 need not consist of a threaded nut. Importantly, it can be made to cooperate with another connection part (not shown) by means of, for example, threads, quick couplings, screw connections, friction, or the like. In addition, the first connecting portion 24 is not limited to a circular or substantially circular cross section, but may, as mentioned above, alternatively be rectangular, square or other polygonal. The same applies, as mentioned above, to the openings 22 in the wall plate 10.

Further, the locking member 3S is not limited to being a locking ring, as in the example 10, but may be, for example, another type such as a threaded ring, an elastic O-ring type or other type of member that locks the first connecting member 24 screw connections.

It should also be noted that the wall plate 10 is of course not limited to a rectangular shape, but may have other shapes. Furthermore, the invention is not limited to the wall passage of two pipes, but the number of pipes may vary.

. Normally, the number of tubes is 1-3, but it is of course conceivable that there may be more tubes.
