Description

Technical field

The invention relates to a gas outlet, which is used on the front to make a fixed connection to a fixed gas line and on the back to connect a gas connection, in particular a gas tube connection, and which has a locking device in the housing which, when the gas connection is connected, only releases the internal gas path after an external seal has been obtained.

State of the art

Gas outlets are used to connect a fixed gas line to a gas-operated appliance such as a household stove, a clothes dryer or a grill, and allow easy connection of gas consumers to the gas line.

Such a gas outlet is described in DE 100 61 653 C1. This gas outlet consists of a base with an integrated input plug to provide a fixed connection to the fixed gas line, an output plug bolted into the base and a base plate enclosing the outer shell of the output support at a defined distance to accommodate the gas connection plug and otherwise bolted to the base plate. The base plate also serves as a wall attachment to which it is also attached. On the base plate a hood is attached which, when disconnected by means of a gas connection, locks the opening of the base plate.

For the use of gas outlets, especially outdoors, it is desirable to increase safety by enabling the gas line to be manually closed; furthermore, removal or insertion of the gas connection plug should be prevented when the gas line is manually opened, which is not possible with a gas outlet of the above type.

To meet these requirements, it is now common to install a well-known ball valve modified for this purpose in the gas line, so that the ball valve does not have a thread on the outlet side as usual but a plug for a gas connection.

This connector has balls of locking positioned in radial conduction openings on the perimeter of the gas outlet, so that they can be moved in radial direction by means of a holding casing moving axially on the gas outlet. Depending on their position, the insertion/removal of the gas connector is allowed or prevented.

In addition, a valve is fitted inside the ball valve and is opened by the gas socket when the gas is introduced.

The disadvantage of this design is that the gas outlet is not covered and thus does not provide protection against foreign objects, nor is it suitable for under-clad installation, nor does it have the appearance that would be desirable for use in the living/view area.

Description of the invention

The present invention is based on the problem of developing a gas outlet of the above-mentioned type which allows a gas outlet to be connected and disconnected rapidly in the residential area. The purpose of this invention is to enable the connection and disconnection only if an additional gas outlet is manually closed. The purpose of the invention is also to provide protection against the penetration of foreign objects when the gas outlet is not connected. The purpose of the invention is to make the gas outlet suitable for use in the dwelling/vision area. The problem is solved by preventing the gas outlet from being connected or disconnected by means of a switch that is located on one side of the outlet, which allows the gas outlet to be disconnected if the gas outlet is located at the bottom of the outlet, or on the other side of the outlet, where the gas outlet is located at the bottom of the outlet, with a switch that is located at the bottom of the outlet, which is located at the bottom of the outlet, when the gas outlet is located at the bottom of the outlet, or at the bottom of the outlet, where the gas outlet is located at the other end of the outlet, with a switch that is located at the bottom of the outlet, which the gas outlet is located at the bottom of the outlet, when the gas outlet is located at the bottom of the outlet, and when the gas outlet is located at the bottom of the outlet, where the outlet is located.

The solution was thus found to eliminate the above-mentioned disadvantages of the state of the art: the switch element is operated manually to open or close the gas line via the shut-off valve and, at the same time, to lock or unlock the gas connection.

The other claims for the invention also show other advantages, such as the advantage of storing the switch in the base plate.

To make the installation and production effort as easy as possible, it is advantageous to have the spindle made in two lengthwise pieces, both connected by a spring element.

A particularly advantageous design is also provided by the flow-through valve having an axially moving valve plate on the nozzle which is attached to a nozzle on the nozzle by the force of a spring acting in the opening direction.

Simple solutions of the gas-connector to prevent the gas-connector from being removed or inserted when the gas line is manually opened are provided by the gas-connector being designed as a latch which is perpendicular to the axis of the output support or by the gas-connector being designed as a swing which has its pivot point between the axis of the shock and the axis of the output support.

It is advantageous to use a clamping ring, which is mounted on the outlet support and is supported by a spring on the latch, which has two symmetrically arranged legs, with balls of clamping in radial openings, arranged in a known way on the outlet support, moving in a radial direction through the inner contour of the latch, by the axial movement of the latch, the type of leg comprising the latch giving the fact that a longitudinal movement of the latch results in an axial movement of the latch.

Another advantageous solution for the use of a latch is to place a wire shaped part in a circular nut of the base support, with two symmetrically arranged, curved legs in the direction of the base support, which are inserted into a narrowing guide cone of the latch, and several ring-shaped grilles are placed on the wire shaped part, which, depending on the distance of the legs determined by the guide cone and the resulting diameter of the wire shaped part in the nut, are inserted into the inner part of the outlet through radial guide openings in the base support.

Example of implementation

The gas outlet according to the invention is described in detail in the following examples of embodiments: 1a closed-cut gas outlet,Fig. 2a view A of the gas outlet from Figure 1,Fig. 3a view of the broken out gas outlet from Figure 2,Fig. 4a detailed view B from Figure 1,Fig. 5a detailed view C - C from Figure 3,Fig. 6a closed-cut gas outlet from Figure 1,Fig.7a second embodiment of a closed-cut gas outlet,Fig. 8a view D of the broken-out gas outlet from Figure 7,Fig.9a third embodiment of a broken-out gas outlet from Figure 10E,Fig. 10E,Fig. 10E,Fig. 10E,Fig. 119.

A gas outlet according to the invention, as shown in Figure 1 in the figure below, is a multi-piece housing 1 consisting of a core 2, a hood 3 and a base 4 that are firmly connected.

In the base 2 there is a screw-in input plug 5 which in this case is fitted with an external wind to make a fixed connection between the gas outlet and a fixed gas line not shown and an output plug 6 which is used to contain a properly tuned gas outlet 57 where the input plug 5 may be a known thermal insulation device, and therefore not described here.

Parallel to the axis of the base support 6, the base 2 has another opening protruding into the gas-conducting chamber 7 through which a gas-conducting valve 8 can be used to close the chamber 7. In this case, the ring-shaped seat 9 of the gas-conducting valve 8 is pressed in. The gas-conducting valve 8 described in this example of operation is also designed as a safety-lock device which automatically closes the gas-conducting chamber 7 when a specified flow rate is exceeded.

The seat 9 of the valve 8 shown in Fig. 4 cut and in an open condition has radial steps 44 at the outlet, evenly distributed over the perimeter, and a central support 10 for a first part 11 of a two-piece 11/12 valve, both parts of which are connected by a spring element 13 in a perfectly shaped way. On the seat 11 which has a valve 16 at its one end, which is conveniently adjusted to adjust/adjust the closing flow described below, a spring 15 is located in the opposite direction of the flow, and a spring 15 is located along the length of the valve 15 and 15 is also located between the valve 15 and the valve 15 as an elastic supporting element of the valve 15 which acts as an elastic supporting element of the valve 15R.

In a socket 19 which closes the opening 14, the part 12 of the 11/12 nozzle is stored longitudinally and gastightly directed outwards.

A base plate 4 also attached to housing 1 is used as a support to a schematically represented pre-wall 45 used in many cases, particularly in housing construction, and to which it is attached in a familiar way, for example by means of screws and bolts, either directly or by means of a separate so-called sub-plug box. A tubular bundle 21 inserted into the base plate 45 in the twelfth quarter encloses the outer mantle surface of the base plate 6 protruding from the base plate 2 at a defined distance, as explained below. For example, the connection of the base plate 4 to the base plate 2 is done by means of screws not shown.

The end of the base support 6 which is inserted into the base 2 forms a valve seat 22 for a gas-tight device 23 whose valve body 24 is mounted in the base 2 on a guide 25 in a direction perpendicular to the axis of the base support 6 and thus also to the valve seat 22. The valve body 24 is loaded in a locking direction by the force of a spring 26 which is supported by one end on the inner wall of the base support 2 and by the other end on the base support 24. To ensure gas tightness, an O-ring 27 on the base support 24 is located in the base base 23 and is attached to the valve seat 22 in the locking position.

In the area of the end facing the base 2 the outlet has 6 several radially oriented conduit openings, distributed in the perimeter but in a plane 28. In each of these conduit openings 28 a ball of barrier 29 is placed, which partly enters the connecting opening 30 and the penetration of the balls of barrier 29 is prevented by a reduction in the diameter of the conduit opening 28 carried out in the direction of the connecting opening 30.

As can be seen from Figure 3, an octagonal contour was chosen to make the manufacture of the clamp ring 31 as simple as possible and to keep the space required as low as possible. The clamp ring 31 is positioned in an axial direction under the action of a bolt of a bolt supporting the body 2 32. The bolt balls 29 are held in place by means of an inner port in the clamp ring 33 depending on the exit of the clamp ring 31 to open 6 orifices in their opening so that they are either 28 or 30 in total, so that they are kept in the opening 30 times so that the opening 28 is completely free.

The base plate 4 attached to the front face 45 shall have a belt 46 at least partially circular, into which the restraint elements 48 in the hood 3 attached to a hood 3 covering the base plate 4 are attached when mounted.

The hood 3 shown in Fig. 2 in the front view of the gas outlet has a longitudinal hole 49 on its front side, behind which part of the longitudinal hole 49 contains the connecting opening 30 of the base support 6 and a break 64 for a switch element, described below.

As can be seen from Figure 3, which shows a representation of the gas outlet from Figure 2 at the far hood 3 and the far cover 51, on each side of the connecting opening 30 there are two conducting rods 52 for each of them in base plate 4 supporting springs 53 which, with their other end, interact with the cover 51 not shown in this view in such a way that the cover 51 closes the area of the long hole 49 which releases the connecting opening 30 of the base support 6 with the gas outlet 57 not plugged in.

Furthermore, by way of an exception 34 of the base plate 4, the switch element 35 already mentioned above is protruding, which is stored in a swiveling position 36 in corresponding bearings located in the base plate 4, with the swivel axis of the switch element 35 in a plane with the longitudinal axis of the bumper 11/12. On its side facing the base body 2, the switch element 35 has a switch contour 37 on which the top of the bumper 12 is supported. The switch contour 37 has two rest positions 38/39 fixed so that the barrier valve 8 is either in the open or in the closed position. To achieve the simplest possible conversion, the feed element 13 serves as a part of the tolerance balance between the two parts of the bumper 11/12.

On its side facing the outlet support 6, the switch element 35 has a cone-shaped aperture 40 in which a latch 41 is located. At its end, facing the switch element 35, the switch element 41 has two symmetrically arranged shanks 42 that enclose the latch ring 31 in a gable shape and protrude into a guide contour 43 located on the latch ring 31, so that a longitudinal movement of the latch 41 results in an axial movement of the latch ring 31. In a simpler way, this is solved by the fact that the two shanks 42 of the latch 41 each, as shown in Fig. 5, clearly show a guide 54 which shows a directed action against the latch 32 as a support against the axial slope of the latch 43 as shown in Fig. 5.

The operation of the gas outlet shown in this example is described as follows:

In Figure 1 the gas outlet is in the closed position, the outlet no. 6 with its connecting opening 30 is covered by the cover 51 and, because of the uninserted gas outlet no. 57, the locking device 23 is also closed. Since the switch 35 is also in the closed position, the nozzle 12 is at the rest position 39 and the valve tray 15 is directed against the O-ring 55 in seat 9 and simultaneously against the O-ring 17 between it and the junction 21, so that the gas conducting chamber 7 is closed. The nozzle 35 is placed through the intake 40 and the rack pushers 41 of the clamp 31 in such a position that the 29 balls are in contact with the 33 ball when the opening 30 is released.

In this position, it is possible to insert the gas connector 57, after the cover 51 has been moved against the force of the springs 53 to such an extent that the connecting opening 30 is released, and to open the locking device 23 via the extension 56. After the switch element 35 has been actuated, the plunger 12 on the switch contour 37 is moved to the resting position 38. The O-ring 17 on the plunger 11 releases the valve plate 15 and a pressure compensation is carried out via a leakage flow between the valve plate 15 and the plunger 11 so that the spring 18 can push the valve plate 15 into the opening position. At the same time, the connection to the installed gas connection line is made in such a way that the opening of the plunger 30 is not blocked and the plunger 31 is not in a position to move.

To disconnect the connection again, the switch element 35 must first be actuated and the valve 8 closed. Only then is it possible to remove the gas connector 57. The gas connector is closed 23. After the gas connector 57 has released the cover 51 under the force of the springs 53, it closes the connection opening 30. The gas socket is closed again as shown in Figure 1.

For example, if a hose break or other failure occurs at the gas connector 57 connected, resulting in a higher closing flow than the one caused by the spring force 18 at the position of the block 16, the valve plate 15 moves against the spring force 18 on the jack 11 and closes the valve 8 acting as a safety closing device.

A modified gas outlet also uses, as described above, a clamping ring 31 mounted on the outlet hub 6 which is axially movable and which, by means of its inner contour 33, influences the position of the bolt balls 29.

However, in base plate 4 a pivoting pivot 62 is stored in a bearing 61 with one end resting in a nut 63 of the clamp ring 31 while the other side is attached to the bolt 12 (Figures 7 and 8). It is understood that the pivot 61 may also be located on the base body 2 and/or that the pivot 62 is connected to the switch element 35.

Another embodiment of a gas outlet is shown in Figures 9 to 11. In this embodiment, which is otherwise in principle in accordance with the prescribed, the outlet nozzle 6 has a circular nut 14 in the area of the end facing the base 2 in which a wire shaft 47 is located, as shown in Figure 11, which has two parallel inclined rods 50 which are inserted into a funnel-shaped guide cone 58 of the crankcase 41 which is in turn stored in the crankcase-shaped receptacle 40 of the switch element 35.

The method of operation is similar to that described in the above example:

Depending on the depth of penetration of the 50 shafts into the funnel-shaped guide cone 58, the diameter of the wire-forming part 47 and thus the radial position of the roller 59 relative to the longitudinal axis of the base support 6 are changed, thus achieving the desired locking of the inserted gas connection plug 57 when the valve 8 is open.

The gas outlet according to the invention is of course not limited to the examples of embodiments shown; rather, modifications, alterations and combinations are possible without leaving the scope of the invention.

For example, the arrangement and/or the way the barrier is made can be changed, the number of barrier balls 29 can be varied, and the gas outlet can be made as a so-called plug-in variant.
