"Gas tap for hose connection"

The pattern lying on the door refers to a gas tap for hose connection.

ils gas connection taps of various designs are known and in use, depending on whether for the respective Gas device a fixed tube connection or a flexible hose connection is desired. Fixed connection taps are standardized and are generally installed by gas works. You own a rooster chick and carry a threaded connection on which the device leading gas pipe is screwed.

These taps cannot be used for hose connection, since gas taps for hose connection according to the existing gate scriptures must be equipped with a safety lock that allows gas to escape when the hose connection is removed inevitably and reliably prevented. ISs are

so-called gas sockets known, in which the hose connection Is designed like a plug, a safety lock is arranged in the can, which allows the gas to escape with removed. Hose inevitably prevents.

jüs is also known a gas tap for hose connection, which is equipped with a safety valve that opens automatically when the hose connection is plugged in and it closes automatically when the hose is removed. This measure is intended to prevent that if the stopcock is opened accidentally with the hose removed, an undesired gas leakage occurs. This gas tap has a housing extension at the tap outlet, which is under pressure Receives valve body. With this housing approach, the hose connection nozzle can be connected, which is preferably done by a union nut happens, which is rotatably arranged on the hose connection nozzle and on one on the housing attachment the threaded connector located there can, with the hose connection nozzle being screwed on the valve is automatically opened against the action of the spring. For this purpose, at the end of the sweet tube connection nozzle a tubular protruding extension can be provided on the shaft part of the valve body comes to rest and when pulling on the union nut lifts the valve body against the peder effect.

When a gas device with a hose connection blows away should be, previously had to be installed from the house

Connection tap for fixed connections can be exchanged for one for hose connections, which is not without Difficulty was possible as changes were made to the installed Gas piping is not possible without further ado and is only carried out by specially authorized personnel may be.

Here the pattern creates an advantageous improvement insofar as the installed standardized connection taps can be used either for fixed connection or for hose connections without the need to change the installed line. J- ¹ IeS is achieved according to the pattern that the 'valve spring receiving part of the housing extension is equipped with an internally threaded connector adapted to the connection thread of the standardized connection tap intended for fixed gas connections, and that the valve spring is dimensioned such that it fits when the housing attachment is screwed on, is supported in the outlet bore of the valve. In the exemplary embodiment, the previously required replacement of the installed standard cock for fixed gas connection with another cock specially created for hose connection is superfluous, since it is only necessary to screw the patterned housing approach onto the connection thread of the installed cock for fixed gas connection, with the safety valve automatically comes into operation. The use of special taps for hose connections is thus superfluous. In addition, the installed tap can be converted to a smart

connection can be made by every craftsman, since Interventions in the installed gas line are not metal required are.

The pattern is further characterized in that the internally threaded nozzle of the housing extension with a removable, the valve spring and the valve, unifying body with the housing attachment to form a component cap, for example made of plastic, is provided. This measure makes the retrofitting of the connection tap much easier, since the craftsman the finished housing attachment with all accessories as a component, j3r only needs remove the cap before assembly and can screw the finished housing attachment onto the connection thread of the installed Hormhahn and thus receive a tap for hose connection corresponding to the gate scripts.

The pattern is further characterized in that the valve body consists of a rectangular cross-section Sealing ring made of elastic material, for example made of a plastic from the PVG series, consists of a supporting plate, and that in the housing approach an annular in front of ·? arranged jumping valve seat which engages with the center of the free surface of the sealing ring is. By using a plate-like valve body with an inserted rectangular sealing ring on the one hand and by arranging a narrow

annular seat on the faucet housing on the other hand a reliable seal is guaranteed even in the event of contamination, since this is for the sealing ring The material used, due to its elasticity, compensates for the irregularities caused by soiling and ensures a gas-tight support on the ring-shaped seat. The model gas tap has thus the essential advantage of absolute gas tightness.

In order to avoid ignoring or playful opening of the valve when the hose connection nozzle is removed, in a further development of the pattern idea as a closing spring for the valve body, a coil spring of such strength used that a closing pressure of at least 14 kg results, so that a playful opening of the safety valve, for example with a screwdriver, is not is possible.

According to the pattern, the valve body and also the spiral spring are made of a stainless steel, for example Hirosta.

The accompanying drawings show an example of an embodiment of the tap according to the sample, and they mean:

Scale.

Jain standardized gas tap 1 is with its union nut 2 firmly connected to the gas pipe installed in the room. The cock 1 has an opposing threaded connection 3 on which the fixed pipeline usually traveling to the gas appliance is screwed by means of a union nut. A known cock plug is arranged in the housing 1, that by means of the handle 4 in the open or closed Position can be rotated. The usual standardized connection taps have 3 connection threads in the sizes: .. 3/4 ", 7/8", and 1 1/8 ". If the tap 1 is on the hose connection If the conversion is to be carried out, the housing attachment is screwed onto the threaded connection 3. To this end the housing extension 5 has a threaded connector on its üinde 6, which, in terms of its length and in terms of the size of the thread, is dem'connection thread 3 of the cock 1 is adapted. For the different taps 1, different housing extensions 5 are provided, their threaded connectors 6 is provided with the corresponding thread of 3 / 4- ", 7/8" or 1 1/8 ". At the bottom of the connection 6 there is a Seal 7 is provided. The opposite end 8 of the housing extension 5 is provided with an external thread and carries a seal 9 · The hose connection 11 is screwed onto the thread 8 by means of a union nut 10.

The hose connection 11 has a tubular protruding Bund 12, which is attached to the webs 13 of a tubular Body creates, which is provided with a continuous axial opening. The üinde of the web 13 is on the back

a-plate-shaped valve body with an annular, Seal 16, rectangular in cross section, made of a flexible material, for example a suitable rubber material is provided. In the closed position shown in Fig. 2, an annular valve seat of the housing attachment is located to the center of the sealing ring 16 and creates a reliable seal. The valve disk 15 is under the Effect of a spiral spring 18 ", which is at its i'nd in the bore 19 of the threaded connection 3 is supported.

The ADb. 1 shows the Hormhahn 1 with the screwed on Housing attachment 5 in. Operating position, d-r h. with screwed on Hose connection 11. When the union nut 10 with the hose connection 1H is removed, lies under the Effect of the spring 18 of the valve disk 15 with its seal 16 on the seat 17 and thus closes automatically the gas outlet so that no gas can escape if the cock plug with the handle 4- is not in the closed position is brought.

Fig. 2 shows the housing extension 5 with the valve disc and the valve spring 18, these parts being combined into a single component by means of the union nut 20, which are screwed into the internal thread of the threaded connector 6 is. When the tap 1 is converted to a hose connection is to be removed, the fitter removes the plastic union nut 20 and can now without further, .- assembly work the housing extension 5 with the threaded connector screw onto the threaded connection 3 of the cock 1, whereby

the valve disk 5 automatically on the valve seat 17 A hose connection is pressed up by means of the union nut 10 is unscrewed.
