Abstract

The application relates to a self-closing tap or valve. In the preferred embodiment the tap is connected to a water supply by the threaded connection 1. The tap is operated by lifting barrel 6, which lifts the cartridge valve 2 and allows fluid flow. When the barrel is released the weight of the barrel and the force of the valve spring close the valve. The valve is characterised by not having any operating levers that could be used to wedge the valve open.

Description

<Desc/Clms Page number 1>
Self-Closing Tap. Ref : SCT.
The invention relates to a water tap or valve, which will automatically close when the operator removes his or her hand from the device.
In many areas where water is scarce, especially in 3rd world countries, a tap, which is left
running, will waste a vital resource.
ZD The object of this invention is to provide a device, which is easy to operate; will automatically close when the operator's hand is removed ; can not easily be tied, fixed or wedged in the open position and which will effectively seal under high and low pressure conditions. The tap is designed to operate vertically.
The device may be made of metal or plastic, but whichever material is selected it must not contaminate potable water.
The invention is explained further with the aid of the attached drawing No: SCT 1/1 where :- Figure 1. shows the external shape of the tap Figure 2. shows a sectioned view of the tap Figure 3. shows a top end view of the tap Figure 4. shows a bottom end view of the tap All parts used in the construction of the invention are numbered and a parts list is shown on the drawing.
Construction of the Invention. Ref : SCT The heart of the invention is a spring loaded non-return valve cartridge (2), which is already covered under UK Patent No : GB 0091164 and which, under normal operation is opened by water pressure against the spring to permit flow and which closes to prevent backflow when the inlet pressure is removed.
In the case of the invention, the cartridge (2) is pressed into a recess in the Body-Top (1) and held in position by its own integral locking ring.
The Barrel (6) is inserted into the Body-Bottom (5) and into the top of the Barrel (6) is inserted an adjustable height cartridge pin (7).
The body-bottom (5) and the Barrel (6) are then assembled to the Body-Top (1) which contains the cartridge (2) and is sealed by'0'Ring (3) and locked together using 2-grub screws (4). The Cartridge Pin (7) is not directly connected to the Cartridge (2) and in the unopened state is clear of it.
<Desc/Clms Page number 2>
In the top of the Barrel (6) are 3 holes (A) drilled on an angle to break into the centre hole (B) of the Barrel (6), and these permit the flow of water which, when it has passed through the Cartridge (2) to flow into the Barrel (6) and then out to usage. Around the periphery of the top of the Barrel (6) is a rubber sealing washer (8), which will seal when the Barrel (6) is lifted up against the bottom of the Body-Top (1).
Method of Operation of the Invention. Ref : SCT The invention is screwed onto an incoming water pipe via the screw thread in the Body-Top (1).
Water will the flow into the invention but cannot pass through it because the non-return Cartridge (2) is closed.
The operator will grasp the Barrel (6) and push it upwards until the Cartridge Pin (7) touches the underside of the Cartridge (2) and lifts it off its sealing seat.
The Rubber Washer (8) on the top of the Barrel (6) will then touch the underside of the BodyTop (1).
As the Cartridge (2) is now open, water will flow through the Cartridge (2) into the cross holes (A) and thence into the centre hole (B) of the Barrel (6) and out to the point of use.
When the operator releases the Barrel (6) the weight of the Barrel (6) will drop it downwards and a combination of the incoming water pressure and the spring in Cartridge (2) will close the invention.
If the incoming pressure is very low, then the Cartridge (2) spring will still be sufficient to give an effective seal.
Example of Use. Ref : SCT.
One example where the invention can be used is say on standpipes which have been erected in areas where there is a water shortage.
The invention would be screwed to a bend on the standpipe and when consumers require water, they place a bucket or other container under the invention, lift the Barrel (6), fill the container and release the Barrel (6).
In refugee camps in Africa and the Far East, standpipe frames are constructed using up to 6outlets.
