Abstract

A lift valve actuated by a float is presented. The form of the piston-like valve member allows for a special pressure distribution on the valve member. The float is mounted on a threaded lever to permit an adjustment of the position of the float with respect to the lever.

Description

I. Technical Condition of the Invention:

As I stacecl In the original (Clearance of Invention) , ihe used traditional floats depend on the .scientific idea which is summarized as the - establishment of equilibrium between water pressure force and Archimedes pushing force ( floating force); so the hole through which water flows is closed by a moving stopple that is moved by a bit wich a floating element tied to its end, where it closes the same and shuts che hole when the water level reaches the required level. If we want co encrease the diameter of the hole to increase the water flow level, it would be necessary ic increase the bulk of the floating element, or the length of the arm bit to increase the force, so that the mechanism would be able to close the hole and control water flow. It is clear that there are warnings and defaults connected to the two methods . The normal float depends on the following equilibriums: xτessu:e force = fiόac force

G x V x ri = p xs x r2

Where ^g: the element weight of water εjπd equals 1 kg/litre, V volume of the floating element in litre ii is the radius of turning of floating element around movement center where the length of bit is in centerneters.

? water pressure in Kg./cm2. S area of hole in cm2, r2 is the arm that moves the stopple and is equal the distance from the stopple axial to movement center

5. Plans & Drawings: enclosed herewith are /6/ drawings a. the new float has rescinded the old one's faults, especially the limited flow rate. It forms no impedence of water-flow in the first model, water control ( valve) with a fixed cork, ( could be a flexible piece of rubber or a conic stopple ) and a mobile nozzle ( mobile pipe) to avoid the pressure effect on the mobile control piece by order of floating element ( previously stopple became now an open nozzle from both ends), so we could carry the pressure force on the fixed stopple which reacts in a reaction that consumes no force or effort to overcome the same. It is also possible to control the flow by means of a relatively small floating element, which is not connected in a growing linear connection.

Consequently, the diameter of orifice could be increased without limitation to reach that of the pipe, or more , without increasing the dimensions of the float in order to overcome the friction forces, soley because it is a cylindrical pipe with no bases, that could not be subject to axial pressure force ( friction forces are faint compared with pressure ones)

The increase of hydro flow will cause the decrease of pumping period ( to fill the tanks) . Yet the new float is easy made and cost effective, it could be made of plastic. Additionally, the wider inner diameter of the pipe will make the working mechanism block the water authentically, with a force equal to the difference between the pressure on the surface subject to water pressure from one side and the air pressure from the other. This feature is quite useful, when using this element as a normal faucet or a valve ( working as a ball valve , yet in a liding manner ). b. As for the other model, which is more developed than this float, I depended in making it on a moving cork or stopple, and a fixed nozzle anew ; and the new idea depends on the subjection of the control element to air pressure from both sides, where it becomes more movable, alone from the water pressure ( pressure forces outcome from all sides will become zero equal) and innately in the direction of stopple direction; this means that there will not be any effect of pressure on it, and could be moved by order of ( float) which is relatively quite small, and would be possible to maintain pressure blocking mechanism by widening the diameter at the outlet nozzle slightly more than the opposite diameter, which equalizes the pressure force , as in the first type, I made some calculations of the surfaces on which the water will flow, and designed the same in a way to make it always more or equal to the transferring pipe's diameter ( with diameters ¹A" ; ³A " , 1 inch and the other different measurements).

I am ready to explain the mechanisms of both ideas on the new float typesr-

I would like to say hers, that I have experimented many types of the float on house water tanks ( in my own house in my father's) ; results had been excellent, and, they are types that do exist, and I am ready to expose them and to explain their working mechanisms in details.

a. in the first type of the original invention clearance

No. 1 175 , issued for the new floats in a new style ( moving nozzle and fixed stopple) it is possible through the increse of flow with two or three folds , along with keeping almost the same volume , water-flow control element ( valve) which is a fine cylindrical pipe from outside which has some width from one side where water flows, when it is far from the fixed stopple, which blocks the same when it sticks to it, by order of the float element and its holder, the surface which is exposed to air pressure from inside will secure closing the valve completely, when using the control element as a faucet or float or valve; all of this had been specified with drawings with the original invention clearance. b. In the second type, which is more simple and developed, I depended on the balancing of pressure forces on the two ends of the stopple, in order to isolate these forces ( the stopple I used is movable anew in closing the valve) by exposing its two ends to air pressure when the valve is closed ( or opened) this lessens the_power required to secure opening or closing the valve to overcome friction powes only, following the cancillation of water pressure on this stopple ( the difference in pressure: water pressure on one hand and air pressure on the other in the normal float).

Claims

4. Claims Requiring protection:Claims requiring protection for the additional invention clearance:

1. idea, form and manner of working of fixed-nozzle valve and the moving stopple which is balanced with reference to pressure forces on it, where I organized them in a way to make them subject to air pressure from both sides in the opening and closing procedures, keeping the ownership right for using both ideas for other hydraulic purposes to control the flow of any liquid or gaz as a faucet or valve separate from the float, and moreover it is

an easy to produce easy to work valve, and of good performance , and to keep the ownership right for its use to maintain the level of any kind of liquid, and to use it as a float for gazoline inside the car-engine carbarators, to reduce their volume, and to use it inside the incoming & outcoming ( inhale, exhale) of the internal combustion engines, in order to lessen the spent power and required force to open the valves ; and consequently the volume and weight of the fixtures used for moving these valves ; and to use it in the shower for instance, and in the western closets ( bidets).

2. hydraulic blocking which closing the valve in an authentic manner to get use of the water pressure, and the difference of the two internally exposed surfaces to water pressure, and to air pressure from outside, in the second type.

3. water-level calibration method, and the form and manner of float element, which I designed as the heart shape, in order to enable the user to calibrate the water level from above or from the narrow end, if he wants to lower the level of water by a step equal to few centemeters, maintaining the possibility of calibration with a quite easy gradings, this is made possible by means of the plastic nut which goes through the heart-shape ( float elemenet) in order to raise or lower it, according to the will of the user, then he could fix the element with a fixing nut.
