Abstract
Valve housing 1 is attached to the end of a pressurised fluid supply conduit. Valve disc 3 is pressed towards valve seat 4 solely by the fluid pressure and is provided with an annular seal 8. Outlet pipe 7 has a rounded end 16 adapted to fit in rounded recess 15 so as to be swivellable to raise the valve plate 3 away from the valve seat 4 and hence allows the fluid to flow through the outlet pipe. <IMAGE>

SPECIFICATION
Valve for the delivery of a fluid under pressure
The present invention relates to a valve for the delivery of a fluid under pressure, and more particularly to valves of the type comprising a valve housing in which there is arranged a valve plate or disc adapted to be pressed on to a valve seat, and directly below the valve plate on the side of the valve seat there is mounted a swivelling outlet pipe whose edge lifts the valve plate when there is a swivelling movement.
It is known to use such valves in apparatus for providing animals with liquid to drink, wherein the animal makes an outlet pipe swivel, possibly through the agency of an additional device, so that the liquid, in this case water, can be allowed to flow through the valve because of the raising of the valve plate. When the pressure on the outlet pipe is relaxed the valve disc in known apparatus is always returned to the inoperative or rest position by spring means so that the supply conduit is blocked again. Further known valves of this kind serve as compressed-air valves and allow easy handling and control for example when blowing-off pattern plates, blowing-out bore holes, blowing cutting fragments away and so forth.
A common feature of such known apparatus is that the sealing disc is pressed on to the valve seat by the force of a helical spring or by elastomeric means. The swivelling outlet pipe is also returned to the position of rest again by the same force or an additional force. Such constructions involve relatively considerable outlay and are therefore expensive, but in addition are also easily prone to develop defects, for example ageing and/or corrosion of springs or elastomeric material.
Furthermore, routine maintenance is not pos sible with the known apparatus, more particularly when using vulcanised-in elastomers; if one of these known valves fails the entire valve has to be changed, involving relatively considerable expense.
An object of the present invention is to provide a valve which, when used for fluids under pressure, does not require spring means for pressing-on the valve plate or for swivelling-back the outlet pipe, which valve can be manufactured simply and cheaply and is also advantageous as regards maintenance.
Accordingly the present invention consists in a valve for the delivery of a fluid under pressure, comprising a valve housing in which there is arranged a valve plate adapted to be pressed towards a valve seat by fluid pressure alone to close the valve, and a movable outlet pipe arranged to move the valve plate away from the valve seat to open the valve for the delivery of fluid. The valve plate, preferably guided in the valve housing, is pressed on to the valve seat simply by the pressure of medium which bears on it. The swivelling outlet pipe may be situated directly below the valve plate, this pressure at the same time returns the outlet pipe, after swivelling, into its neutral position, thus dispensing with any need for additional means for aligning the outlet pipe.The valve plate is also provided with a resilient sealing means at the side facing towards the valve seat, so that the valve seat can be formed directly in the valve housing. This not only avoids the need for the production of grooves and the like for the insertion of sealing rings but more particularly obviates the difficult, time-consuming replacement of such sealing rings when their resiliency has diminished and thus the valve no longer seals effectively. If the resiliency of the sealing means arranged on the valve disc is found to have deteriorated it is sufficient simply to replace the valve disc in question, and a precise positioning of the valve disc and alignment of the sealing means relative to the valve seat is ensured due to the guidance provided by the valve housing.
Thus by avoiding the need for springs or elastomers for bringing the valve forcibly back to the neutral position, the valve according to the invention may be produced simply and therefore cheaply, and is also advantageous as regards maintenance, since it is simply necessary if appropriate to replace the valve disc with its applied sealing means.
Conveniently the sealing means is a ring of resilient material which is bonded to the valve disc. More particularly, the sealing means may project beyond the perimeter of the valve plate to provide friction at the guide surface of the valve housing and so prevent any sudden undesired opening of the valve. The same effect may be obtained if the valve housing according to the invention narrows conically towards the valve seat. It is also possible for this purpose to form grooves in the valve housing a short distance above the valve seat, and these may be made spiral in form. A further advantage of this is that when the valve is opened a small amount, a small throughflow cross-section is presented first of all, so that the medium under pressure does not flow out suddenly, and likewise the full possible throughflow quantity is not suddenly stopped when the valve is closed.Thus the dynamic effects on the valve and on the piping system caused by opening and closing the pipe remain relatively slight. In a further embodiment of the present invention the valve housing may be formed from two parts which are attached together in the region of the valve seat.
An embodiment of the present invention will now be described by way of example with reference to the accompanying drawing which is a sectional view of a valve according to the invention in a closed position. Valve housing 1 is screwed to the end of a supply conduit (not shown), for example a water supply conduit in which the water is under pressure. The water pressure acts in the direction of the arrows 2 on a valve plate or disc 3 which is pressed on to a valve seat 4. The valve disc 3 is provided with an annular seal 8. The valve housing 1 comprises an inwardly extending rim portion 5 whose internal side 1 5 is spherically rounded to form a spherical recess. In the recess an outlet pipe 7 is mounted by means of a rounded cup-shaped head element 1 6 so as to be capable of swivelling movement.Outlet pipe 7 is sealed by a sealing ring 1 2 arranged in a groove of the spherical recess 15. To prevent the valve disc 3 from falling out of the valve housing 1, a perforated cover plate 10 is screwed into the valve housing 1 above the valve disc 3.
In the illustrated closed position the water pressure acts on the valve disc 3 so that the sealing layer 8 is pressed securely against the valve seat 4, and thus the valve is closed.
After a swivelling movement of the outlet pipe 7 as is illustrated by the arrow 11, the upper edge of the cup-shaped head element 1 6 presses on the underside of the valve disc 3 and in so doing lifts the valve disc 3. As a result the medium can flow through past the valve disc 3 under the sealing layer 8 and out through the outlet pipe 7. When the force swivelling the outlet pipe 7 is reduced or discontinued, the valve disc 3 is again pressed by the pressure of the fluid present in the supply conduit on to the valve seat 4, the outlet pipe 7 also being returned to the closed position.
If the sealing layer 8 is found to have aged so that the valve no longer seals properly, the valve disc can simply be replaced together with the sealing layer arranged on it, which is an operation which can be carried out without difficulty and with very little outlay.
