Abstract

As water/liquid is drawn off tank 5 the float/arm 3 will fall, opening the valve 6 partially. Water/liquid is discharged into reservoir 1 (FIG 2). By the time reservoir 1 is filled to the top of syphon tube 2 the weight of water/liquid causes float/arm 3 to fall further opening valve 6 fully (FIG 3). Water/liquid fills reservoir 1 to the brim and cascades over the top, a lesser quantity syphons down tube 2 (FIG 4). Float 4 now less buoyant will rise as tank 5 fills until valve 6 partially closes (FIG 5). When this happens discharge from syphon tube 2 is greater than discharge of feed nozzle 7 (FIG 5), As reservoir 1 empties float 4 becomes more buoyant and rises shutting off valve 6 in a few seconds (FIG 6). Tank 5 will now contain more water/liquid than it would, had reservoir 1 not been fitted. This excess water/liquid can be drawn off before the valve 6 reopens. Tank 5 can be fitted to standard ballcocks by screws bolts, glue or moulding to arm 3.

Description

1 BALL COCK VALVE REGULATOR This invention relates to a ball cock valve

regulator.

2302394 As far as 1 am aware there are no inexpensive ball cock valve regulators in existence that can carry out the functions 1 require. This invention works in conjunction with ball cocks. Ball cocks are well known and comprise of a valve, arm and float (usually ball shaped). Their purpose is to automatically fill tanks/containers with waterfliquid. They are governed by the amount of waterlliquid in the tankicontainer and are noisy, relatively slow in operation and take time to finally stop flowing. When a small quantity of wateriliquid is drawn off, the valve opens at a trickle and is very slow to close again. There are however, various ways to overcome this problem by using electrical valves, pressure vessels or complicated valve arrangements. Electrical valves need plumbing in and are relatively expensive. Pressure vessels are bulky, need plumbing in and maintenance. Valve arrangements need plumbing in and are relatively expensive.

1 wanted an inexpensive way to speed up the opening and dosing of the valve and to stop it from functioning when small quantities of waterfliquid were drawn off. This is because a new generation of electrical pumps are available to feed the waterlliquid to the ball cock. These pumps switch on and off by the flow of the water/liquid. Ball cocks interfere with the pumps flow mechanism, especially when flowing at a tickle, this causes the pumps to frequently switch on and off wasting energy. 1 wanted a devise that would allow small quantities of water (wash hands for example) to be drawn off the tank without opening the valve and stop the electrical pump from operating. 1 also wanted the valve to open and shut relatively quickly, firmly and smoothly to assist the pumps operation.

According to the present invention there is provided a regulator which consists of a reservoir to collect wateffliquid and contains through its body a syphon tube, strategically placed with the means to be attached to a ball cock. The regulator is mounted above the water line and is affixed to the float arm.

2 The drawings have been draw in such a manner as to allow the intemal viewing of the reservoir. Referring to the drawings, the ball cock valve has a top discharge conforming to B Standard 212. The ball cock valve regulator as described, works as follows. Waterlliquid is drawn off the tank 5. eventually the floatiarm 3 and 4 will fall, opening the valve 6 partially. Wateriliquid is discharged into the reservoir 1 FIG 2. By the time the reservoir 1 is filled to the top of the syphon tube 2 the weight of the wateffliquid ca. c the floatiarm 3 and 4 to fall further thus opening the valve 6 fully FIG 3. The main body of the waterlliquid fills the reservoir 1 to the brim and cascades over the top, a lesser quantity syphons down the syphon tube 2 FIG 4. The float 4 now less buoyant with its extra weight will rise as the tank 5 fills until the valve 6 partially closes FIG 5. when this happens the discharge from the syphon tube 2 is greater than the discharge of the feed nozzle 7 FIG 5. As the reservoir 1 empties and the weight of the waterlliquid therein decreases, the float 4 becomes more buoyant and rim shutting off the valve 6 in a few seconds FIG 6. The tank 5 will now contain more waterlliquid than it normally would. had the ball cock valve M9ulator not been fitted. This amount of excess waterlliquid can be drawn off before the valve 6 opens again.

FIGURES FIG 1 Shows in perspective, a ball cock valve regulator attached (not shown) to a conventional ball cock float arm 3. The ball cock valve regulator, as described, shows the empty reservoir 1 after the initial fill. The float 4 is hold low in the wateriliquid by the valve 6 stop. The waterlliquid level in tank 5 is at full level.

FIG 2 A quantity of waterfliquid has been dram off the tank 5. The valve 6 just opening. A trickle of water flowing from feed nozzle 7. Watedliquid being collected by reservoir 1.

FIG 3 Shows valve 6 almost fully open. Waterlliquid pouring into reservoir 1 from feed nozzle 7. The waterlliquid level In reservoir 1 at bend in syphon tube 2. The float 4 is lower in the wateriliquid than in FIG 2. The wateffliquid level in tank 5 is similar to FIG 2.

FIG 4 Shows valve 5 fully open showing maximum flow from feed nozzle 7 into reservoir 1 and waterlliquid cascading over brim of reservoir 1 into tank 5 and waterlliquid flowing from syphon tube 2. The float 4 is lower in the wateriliquid than in FIG 3. The ball cock valve regulator is at its ma)dmum weight. The water level in tank 5 is rising, as compared to FIG 3.

FIG 5 Shows valve 6 almost closed the wateriliquid flow from feed nozzJe 7 reduced. Watenliquid flowing from syphon tube 2. The float 4 is in a similar position to FIG 4. The ball cock valve regulator is discharging all the waterlliquid from the reservoir 1 into the tank 5 and getting lighter in weight. The waterlliquid In tank 5 is almost at full level.

FIG 6 Shows the valve 6 tightly closed waterfliquid stopped flowing from feed nozzle 7. The contents of reservoir 1 draining down syphon tube 2. Float 4 slightly rising as compared to FIG 5. Waterlliquid level in tank 5 at full level.
