The invention relates to a flanged device, in particular, but only applicable in sanitary and heating devices.

More precisely the present invention relates to a device flange type, containing the flange and the mating flange that can be tied to each other, and applicable water heaters with heat storage.

As you know, the heaters with a thermal battery have a cylindrical part called "cuff", which is closed with two caps, one of which has a hole through which passes at least the shell of a thermal relay (contains one or more temperature sensors), corrosion of the device and optionally one or more electric resistances (in the case of electric water heaters with heat storage), while such components are typically installed on the flange, which also serves to seal the said opening. As you know, the flange is pressed against the circular mating flange, the outer edge of which is welded to the cap, and its inner edge is usually made in the form, for example, bending, leaning on the edge of the hole in the cap.

To ensure an airtight seal between the space inside and outside of the water heater between the flange and cap set sealing element of elastic is on the material.

In widespread flange device popular for several years (see, for example, patent IT 1305508, issued in the name of the applicant of the present application), the flange and the mating flange tied to each other by a set of clamping screws with or polygonal shaped head, the rods which pass through special slits made in the mating flange (in particular, in the area of abutment between the said outer and inner edges, see, for example, figure 2 of the above document) and through corresponding holes in the flange. On the said rods corresponding screw lock nuts until they are pressed against the flange. When tightening these nuts sealing element is compressed between the flange and the cap (mainly in the area of the holes), resulting in a tight seal.

The Assembly operations such flanged devices are particularly Disfavored long and complicated, for example, due to the complexity of the automation and acceleration. It is known that after the manufacture of the mating flange by forming and attaching, as briefly described above, to the appropriate cap, it is necessary that at least the first collector on the Assembly line insert locking screws into the slots in the mating flange, and at least a second collector set flange in the center and NASA is Il it on the threaded rods screws. In addition, a second collector are placed on the rods nuts that will be tightened to the third collector. Clearly, this Assembly requires excessive use of the labour force, which affects the time and cost of manufacture.

The slots in the mating flange are quite complex articulated form, necessary to accurately set in their heads and rods clamping screws, which may not always be done quickly and promptly. In addition, due to the shape of the slots, the locking screws occupy an uncertain position, forcing employ collectors to insert the locking screws and install the flange nuts.

For this purpose, and for more details on the above-described flange device, you will refer to repeatedly mentioned patent IT 1305508. Bending the holes in the cap to lock the mating flange requires the involvement of specialized personnel and perform additional operations, which prolongs the time and increases the cost of manufacture of the water heater as a whole.

The present of the invention is to overcome at least part of the above disadvantages by creating an improved flange of the device. In particular, the main objective of the present invention is the creation of an improved lanciego device, which should allow for simple, easy and quick Assembly of the heater.

The second objective of the present invention is to provide inexpensive in manufacture and Assembly of an improved flange of the device.

A third objective of the present invention is to provide an improved flange device capable of providing a certain position of its parts can be assembled on the known Assembly machines.

One of the additional objectives of the present invention is to provide an improved and simplified flange device to provide mechanical strength, reliability and accuracy of the connection flange-mating flange by analogy with the known from the prior art systems of the flanges. These and other objectives of the invention, which will be discussed in detail hereinafter, are achieved by the flange of the device according to claim 1.

To achieve these tasks, a flange unit water heater with heat storage, located near the holes drilled at least in the cap of a water heater with a thermal battery containing:

the flange which is based on the heating and pressure relief device and which serves to seal the said holes,

the mating flange rigidly CIDP is plenny to the cap,

sealing element located between the flange and the outer surface of the cap, in which the flange and the mating flange can be pulled with each other using a variety of clamping screws having at least one cylinder, and a threaded rod,

the mating flange by the method of plastic deformation is attached a threaded sleeve, in each of which includes a threaded rod clamping screws.

In addition, the mating flange is located between its outer edge and inner edge of the support wall to which the method of plastic deformation is attached a threaded sleeve that fit between the support wall and cap.

A threaded sleeve riveted to the supporting wall.

The outer edge of the mating flange attached to colposcopes welding.

The sealing element is a ring of elastic material having a surface, is pressed against the inner edge of the mating flange, and the surface is pressed against the respective surfaces of the flange.

A water heater with a thermal battery that uses at least one flange proposed device

The characteristics of the present invention will become apparent from the following further description of the preferred variants of its implementation, as described in the claims and in order not restrictive in the EPA, illustrated in the accompanying drawings, in which:

figure 1 shows a lateral incision proposed invention flanged devices in General,

figure 2 shows a view in plan of the mating flange proposed invention the flange of the device.

Position 1 in figure 1 generally indicated flanged device according to the invention.

More precisely, in figure 1, for simplicity, shows only the cap 2 (in particular, the cap 2 water heater with heat storage, located at vertelney axis) known water heater with a thermal battery made hole 201, in which a known manner insert shell thermal relay (contains one or more temperature sensors), corrosion of the device and the group of heating elements (electric resistance in the case of electric water heaters with heat storage), not shown in the drawings and hereinafter generally called "heating and a safety device.

In addition, the position 202 marked inlet pipe for cold water supply to the water heater with heat accumulator through the cap 2.

In the hole 201 is installed and fastened proposed invention the flange device 1. As you know, the flange device 1 includes a flange 11, which is based on the above-mentioned "heating of the part and of the safety device, and the mating flange 12, which, as shown, is pressed to the flange 11.

The flange 11 is also used to seal the openings 201 in the cap 2.

In addition, position 13 marked the sealing element, for example, a ring of elastic material, which is placed between the flange 11 and the surface of the cap 2 mainly on the edge of his hole 201.

More precisely, the mating flange 12 preferably has a ring shape and preferably C-shaped cross-section.

Accordingly, the mating flange 12 has an outer edge 1201 welded relief or condenser welding (or other known methods of welding or connection) to the cap 2, and the inner edge 1202, just based on it near the hole 201, that is, the inner edge 1202 merely serves as a shoulder (hereinafter - shoulder 1202) for the sealing element 13.

Between the outer edge 1201 and shoulder 1202 is support wall 1203. According to the prior art (see patent II 1305508), heads of clamping screws are typically placed in the space between the cap 2 and the supporting wall 1203 of the mating flange 12. Threaded rods screws passed through the shaped holes in the support wall 1203, and screw nuts on them, in order to press the flange 11 through which pass the said rods) to the mating flange 12.

On the other hand, in accordance with the invention is referred to the space occupied by a threaded sleeve 3, regularly spaced around the hole 201 and at a distance R along the radius from its center (see figure 2). For example, figure 2 shows the mating flange containing 5 threaded bushing 3.

A threaded sleeve 3 are attached to the base wall 1203 known methods of plastic deformation, such as riveting or caulking. In addition, in one of the preferred embodiments of the invention a threaded sleeve 3 is placed directly during (cold) forming the mating flange 12 by means known as such special equipment.

Then the clamping screws 4 (head 402) is screwed into the threaded sleeve 3, to clamp the flange And the mating flange 12.

Accordingly, as is known from the prior art, in the flange 11 with holes 1101 for the passage of threaded rods 401 clamping screws 4.

Mentioned openings 1101 are located on a circle, the radius of which is equal to the aforementioned distance along the radius R, and are separated from each other, as well as the appropriate threaded sleeve 3.

At this stage you can briefly describe the method of fastening the flange of the device 1 according to the invention.

After forming the mating flange 12 (which according to the invention is already equipped with bushings 3) and subsequent welding of the cap 2 as already described, the flange 11 and the sealing ring 13 is set in the center relative to the of thence 12, more precisely, the holes 1101 in the flange 11 dock and set in the center of the threaded bushing 3, and the surface 1301, 1302 and 1303 of the sealing ring 13 is pressed against the shoulder 1202 of the mating flange 12 and the surfaces 1102 and 1103 of the flange 11 (see figure 1). Then into the holes 1101 in the flange 11 of the insert clamping screws 4 and press them to the threaded sleeves 3 (for example, using a known automatic equipment until their cervical 403 will not be pressed against the upper surface of the flange 11), which occupy a certain position.

As mentioned, with the sealing ring 13 is compressed between the flange 11 and the surface of the cap 2 until it snaps into place in order to provide an effective seal between the space inside and outside of the water heater and at the same time, high mechanical strength and reliability (also at a significantly higher pressure than the working pressure of the water heater) connection flange-mating flange.

Thus, it is clear that in the above-described flange device 1 can be achieved these objectives of the invention. In particular, the main advantage of the flange of the device 1 according to the invention is more rapid and simple installation of the flange 11 on the mating flange 12 as simply tighten the screw 4 on the corresponding threaded sleeve 3, which is already installed on the mating flange 12.

In fact, the difference from the prior art are not used lock nuts (and associated gaskets), which firmly pull on the rod special screws, which are manually set in the profiled slots in the mating flange. Due to certain provisions of parts 12, 3 and 11 (of the mating flange, bushing and flange) the whole process of assembling the flange of the device 1 becomes easily automated and requires less labor, which allows it to borrow at least part of the collector performing other works.

By excluding one or more items flange device 1 (in particular, nuts and gaskets) reduce Assembly time and the necessary manpower is also significantly reduces the cost of production.
