Description

GERMAN

The invention relates to a new design of a regulating valve for the flow of water to self-drinking basins for animals and similar facilities, where a gentle, impact-free as possible Inflow and outflow is desirable.

There are already self-drinking basins known in which the water inflow to the basin shell through a flap operated by the animal is controlled, through which a pin valve with sealing cone and an existing double valve arranged in front of this valve is actuated. It is also already known, instead of a metallic ball for the ball valve, an elastically deformable ball From rubber or the like. To use, which is deformed in its highest position so that it is the Throttles the water flow to the basin. One has here the shaft of the pin valve is already provided with an axial bore into which radial transverse bores open to the inlet and outlet of the water. It is also known to post the pin valve its release by spring pressure returned to the closed position.

It has been shown that when using ball valves, especially rubber balls, the Sealing along a relatively large area takes place, both when opening as when Closing the valve easily leads to sudden jolts, which make precise regulation difficult and a result in undesirable stresses on the closing organs with premature wear.

For float-controlled line closures, double valves are already known, which consist of two there are ball valves that close against the line pressure and are separated by an intermediate piece, which are always opened and closed at the same time, so no gradation in the effect of the Allow water flow. In other known double valves, the movement of a larger one is indeed Valve body made independent of that of the smaller valve, in the sense that it only takes place, when the latter has already come a certain way. Here, too, it is not a step-by-step process Effect and no security against a sudden impact is given.

The invention relates to a regulating valve for the drainage of water to pools of any type that is also designed as a double valve, but in which these disadvantages of the known double valves are thereby avoided that a pin valve of the usual type and independent of this only when actuated in the lifting direction, cone valve interacting with it in a force-locking manner is arranged that only after covering a certain dead gear of the od via a flap.

actuated pin valve is raised and then opened further at the same time as this. When opening of the valve so the dead gear of the pin valve must first be overcome, during which water cannot yet flow through the valve; only then is the cone valve depending on Setting raised to a greater or lesser extent and thereby the water inflow by known per se Ouerbbohrungen and an axial bore connected to these released in the shaft of the pin valve.

If the pressure on the actuating flap ceases, the pin valve first returns to the closed position, whereby the water supply channels are closed; this is followed by the cone valve under the action of a spring or under the action of gravity or in another suitable manner returned to the closed position. Both when opening and when closing it is achieved that at first only a small amount of water can pass through, which only gradually increases, so that the opening and closing even at the highest occurring water pressures completely push and goes without kickback.

An embodiment of a regulating valve for a self-drinking bowl for animals is shown in the drawing shown in schematic form. Analogously the same arrangement can also be used for Find toilet flushers and similar purposes.

Fig. 1 is an axial section through the entire valve;

Fig. 2 shows on a larger scale a partial section through the cone valve and the adjoining part of the pin valve.

Eye 2 and the inflow connection 3, which is provided with an external thread, is connected to the pool body.

4 is the end cap, with the interposition of the pinch sealing ring 5 with adjustable depth can be screwed into the housing. The pin valve is guided in the lower part of the housing, which has a cylindrical shaft 6 and a conical sealing part 7, with which it on the valve seat 8 of the housing is seated.

Above the pin valve sits in the cone cup 9, the cone valve with sealing cone 10, the lies against the valve seat 11 of the conical cup. The cone valve is under the load of a helical spring 12, which lies within the valve chamber 13 and seeks to press the valve onto its seat. the The spring is supported against an abutment in the end cap 4.

The upper shaft 16 of the pin valve has, in a known manner, an axial bore 17 into which above one or more cross bores 18, 19 for the inlet and below a transverse bore 20 for the outlet flow out.

The cone valve protrudes with its shaft-shaped, also axially pierced extension 21 into the bore 17 of the shaft 16 into it. The axial bore 22 is in communication with a transverse bore 23, the is guided by a guide extension 24 of the cone valve.

The conical cup 9 is sealed in the housing 1 by a rubber ring 25.

This device works as follows:

If the pin valve 6, 7 is raised by actuating the flap 26, it first covers a short dead gear α of, for example, about 4 mm before its shaft 16 comes into contact with the valve cone 10 in a non-positive manner. Only when the latter is also raised can water first pass through the small, angled channel 23, 22 from the valve chamber 13 and flow through the bore 17 and the transverse bore 20 via the space 27 and the pin valve into the basin.

When the double valve is raised further, the transverse bores 18, 19 then come into open connection with the valve chamber, whereupon a larger amount of water can flow through.

The flow of water to the valve chamber 13 can thereby be regulated depending on the existing water pressure be that the end cap 4 is screwed more or less deep and thus the metallic Annular gap between the lower edge of the end cap and the opposite surface of the conical cup is opened more or less wide.

If the flap 26 is released again, the process takes place in the opposite direction, whereby a sudden closing by connecting the two valves in series is also avoided.
