DESCRIPTION:
BRIEF SUMMARY
The invention relates to a combined valve device for the draining of vessels and pipe devices consisting of pipes for liquid and air, such as for bubble bath, comprising a housing, a first valve for the liquid pipe and a second valve for the air pipe, as well as means for operating and actuating the respective valves.
In combined pipe devices, i.e., pipes for water and for air, for instance of the type applied in bubble bath, it is essential to be able to drain practically all the water after use. It is almost impossible to prevent water from entering the air pipes in such combined pipe devices when these are in use. This is however not too critical. The essential point is, after use, to have the possibility to completely drain the pipes for water, so that no water is left in any of these. Such water, often waste water, will soon become putrid and create odour in the surrounding area. The water will also represent a potential source of corrosion.
From FR-2557175 there is known a combined valve device for draining vessels and pipe devices, such as those used in bubble bath, comprising a housing, a valve for the liquid pipe and a valve for the air pipe, as well as means for operating and synchronized actuation of the respective valves. By means of two separate wires or lines it is intended that the two valves shall be handled synchronously in relation to each other. However, just a small a mount of slack will prevent sufficient opening of the valves to allow for draining. Furthermore, the pipe is devices and the positioning of the valves are such that complete draining of the air pipe difficult.
According to the invention there is provided a combined valve device of the type mentioned in the introduction, which is characterized by one and the same, rigid actuating means, activating or opening and closing the valve for the pipe for the liquid and the valve for the air pipe.
The first actuating means may advantageously be a lever, rotatably mounted in the housing. The lever may be journaled in one end.
The first valve may advantageously be a conventional closing valve for tubs and basins, which is kept closed by means of its own weight and/or the liquid pressure. The other valve may be a spring-loaded closing valve which is continuously kept in a closed position but which may be opened against the spring pressure.
When not necessary, the lever may be designed and positioned in relation to the respective valves in such a way that the valves open/close simultaneously. This is however not a necessity and the lever may be designed so that one of the valves opens or closes somewhat before the other.
The operating means may consist of a rotatable device which by means of a wire or a line activates the respective valves.
The housing preferably has an opening or fitting designed for connection to an overflow pipe.
The second valve is suitably detachable from the housing by means of a cap which forms the seat for the spring which holds the valve in a closed position.
The valves may advantageously be spaced in relation to each other so that the design height of the valve device is low, i.e., the valves are spaced horizontally at a distance from each other.
Other and additional objects, characteristics and advantages will be evident from the following description of one presently preferred embodiment of the invention, which are given for the purpose of description, without thereby being restrictive, and given in connection with the enclosed drawings wherein:
FIG. 1 shows schematically the combined valve device according to the invention, connected to a bathtub and an overflow pipe,
FIG. 2 shows schematically and in cross-section the combined valve device according to FIG. 1.
FIG. 3 shows a partial view of the valve device according to FIG. 2 and shows the valve for the air pipe in its separate components, and
FIG. 4 shows a side view of the valve device where the lead-in housing for the actuating line is shown in cross section.
Reference is made to FIG. 1 where the combined valve device 10 is shown in connection with a b
