DESC:FIELD OF INVENTION
This invention relates to water tank generally used in storage of domestic water (and industrial also) fed by municipal water supply. Traditional water tank supply system has many big problems. This invention is presenting a new design of water storage for domestic tanks, which doesn’t overflow, is insects free, durable and cheap. In this design whole volume of the tank can be used for storing water, which is not possible in tradition tanks.
BACKGROUND OF THE INVENTION
Uninterrupted water supply in home and industrial areas is essential requirement. For continuous water supply, tanks are commonly used. These are usually made of cement concrete, plastic or any other material. There are three way to feed the tank.
1. By personal tube well and motor pump/submersible system. This category covers nearby 35% of total tanks.
2. Automatically by municipal or colony high pressured water supply. This category covers nearby 55% of total tanks.
3. Motor pumps are used to boost municipal or colony water supply ifwater does not runs in high pressure. This category covers nearby 10% of total tanks.
Thus we can say that nearly 55% water tanks does not require any kind of motor pumps or electric pump. This is a big segment, tanks of this segment have many problems and faults such as the full capacity of tanks could not be used, overflow due to non-durable anti-overflow components which leads to wastage of water, also dirt- insect entry and outbreak. This invention is focused to solve these problems.
There are no such art, which are able to check the entry of insects to water tank. There are no arts found related to ready-made tanks in which water fills up to its full capacity. Nearly 7 % to 15% volume in upper side of the traditional tank could not fill due to installation of inlet pipe and anti-overflow device. If we leave these two merits than some arts are exist for this type of tank segment which work to check overflow of water.
I. Open float ball valve system: - This device installs inside the tank connected to inlet-pipe. This is very sensitive device. This device has no long life. At high pressure float ball valve became fail. This is not compulsory to install. We cannot use full capacity of tank with its use.
II. Closed chamber float ball valve system: - This is some compact form of open float ball valve device describe as above. This is some more durable than this but all other demerits of upper float ball valve system also exist in it. As tank cannot be full, tank is not insects free, the device is not durable etc.
III. Limit switches anti overflow system: - This device works only in those tank which are supplied by motor pump. Because of our focused tank category fills through high pressure water so this art does not relates to us. It is also to be say that this system is not insect free andthis device has fear of electric shock.
IV. Electric circuit base anti-overflow system: - As above.
V. Mercury base switch system: - As above.
US20150225228; Garry L. LaPoint discloses a method of controlling overflow in a below-ground transfer pump sump used in the dispensing of liquid fuels. The method comprises providing a sump having a sump bottom below a level of ground immediately adjacent the sump, providing a storage tank having an internal cavity for the storage of liquid fuel, the storage tank having a conduit in communication with the sump and providing an overflow assembly having an inlet disposed within the sump and an outlet communicating with the conduit. The method includes permitting water from the ground adjacent the sump to enter the sump and mix with any liquid fuel in the sump and if the liquid fuel and water mixture in the sump reaches a predetermined level, allowing the liquid mixture to pass through the overflow assembly, into the conduit and into the storage tank containing the liquid fuel.
US20040007264A1; Anthony Bootka discloses a control circuit for a plumbing device that has a drain line and a water supply line includes a water sensor generating a potential overflow level signal in response to the water level in the plumbing device caused from a restricted drain line, an electrically controlled valve coupled to the drain line, and a controller coupled to the water sensor and the valve. The controller closes the valve in response to the potential overflow level signal.
US7114879B2; Henry K. Obermeyer discloses an invention which relates to improved water control gates and related inflatable actuators, and associated sealing, manufacture and operation apparatus and methods. Advancements in technologies related to air fitting design, inflated bladder stress relief, inflatable bladder strength enhancement, water gate related slide friction mitigation, abutment and other impounded water seals, gate panel fabrication, traffic accommodating water impoundment structures, and water gate panel system operation efficiency, as well as nappe areation, hinges, and bladder manufacture technology are disclosed herein.
US6729367B2; Michael Leroy Peterson discloses an overflow prevention system and method for storage tanks includes a flow disturber situated in the tank fill tube, a fluid level sensor for sensing fluid level in the tank, and an actuator that causes the flow disturber to move toward the fill tube inlet in response to rising fluid level sensed by the fluid level sensor. The flow disturber is arranged to travel between a first position in which it does not cause turbulent flow in the fill tube and a second position in which it causes turbulent flow. The actuator is responsive to the fluid level sensor to move the flow disturber to the second position when a predetermined fluid level is reached. The transition to turbulent flow triggers the automatic shut-off feature of the dispensing nozzle to prevent the tank from being filled beyond the predetermined level.
Demerits of Prior Arts
1. Could not use full capacity of tanks due to inside installation of these anti-overflow devices.
2. These devices are very sensitive and low life so become defected after one or two or year.
3. These tank are lie-back open because cap of tank cannot tight properly with it. So insects, monkey, birds, tree leaf, lizard and dirt enter to tank and cause disease.
4. Where water is supplies at high pressure (through municipal supply or overhead tank) these traditional devices are not successful.
5. These devices are not in-built with tank so nobody is bound to install it. Further in absence of this devices water occurs wastage.
Result of water wastage
I. Wastage of invaluable water runoff into drain.
II. Pending or water logging on terrace cause damp in roof and wall, rust in slab bar, weakness in plaster, breading of mosquito, and insects, leakage in roof, spot in colour etc.
SUMMARY OF INVENTION
To remove problems of above said nearly 50 to 60% of total water storage tank which are fed by municipal or colony's high pressure water supply and which doesn’t need electricity, motor pump or submersible pump is the objective of this invention.
1. The principal objective of this invention is to provide a durable anti-flow device for tanks which are fed by colony or municipal water supply at high pressure and thus needs no electricity or motor pump to feed water.
2. The second principal objective of this invention is to prepare an insect or lizard, and dirt free water tank so as to avoid diseases.
3. The third principal objective of this invention is to use whole space of tank for water storage.
4. Another major objective of this invention is to provide an in-built anti overflow system.
5. Final objective of this invention is to prepare a low cost water tank with these merits.

DETAIL DESCRIPTION OF THE INVENTION
As per figure no. 01 there is a tank (1) with an air tight cover (2). An inlet pipe (4) is connected with tank (1) for water supply with a gate valve (5) to control the flow. A dirt and Insect filter (23) is also placed at inlet pipe (4) mouth. A water outlet pipe (7) is connected to the tank (1) for water supply, which is controlled by a gate valve (8). This water outlet pipe (7) is connected to a supply line with gooseneck (31).
Connection of cover (2) with tank (1) should be airtight, for this purpose, outside threads (3) at tank mouth and inside threads (9) are provided inside the cover (2) (as per figure no.03 and 02). A soft rubber ring (6) is placed between tank (1) and cover (2) for easy and perfect air tightening of the tank (1). For easy opening and tightening of cover (2), wings (10) are provided outside.
As per Figure no. 02 tank, cover (2) has a raised hollow cylindrical shape wall (11) with a hole (29) having outside threads (12) to fix and hold connecting bends (13) over it. Connecting bends (13) have sockets at both side numbered as (15) and (16). Both sockets have inside threads numbered as (14) and (17). The connecting bends (13) is further connected with another bend (18) which has outside threads (20) at its connecting end (19) and inside threads (29) at free (21). An insect barrier (22), is to befit in this free end (21) to check/intercept entry of insects from atmosphere to tank. This barrier (22) has outside threads (28) and filter (31). For easy removal of insect barrier (22) little wings (32) are provided. The barrier (22) can be removed from free end (21) for cleaning, maintenance or any other purpose and for this work inside, threads (29) are provided at end (21) of bends (18).
A disc(24) is in-built with bend (18) which has a hole (25) in the centre. A very soft and circular shaped rubber seal (26) is fixed with screw (27) at the top of the disc (24). There is a hole (30)at the top ofthe disc (24) to hold the screw (27). Rubber seal (26)is tied with the disc (24) through said screw (27).
The working of tank start after installation of all components.When water enters the tank, the inner level of water raise and air existing inside the tank escapes through hole no (25). Further raising water touches the cover's (2) ceiling, then entering the end portion (13). Due to incoming more water into tank (1) water start flowing through hole no. (25) Forcefully. Thus water push rubber seal (26) and moves it toward the disc (24). Further rubber seal (26) closes hole no (25). In this position tank become closed vessel, so incoming of water stops automatically. On the other hand "due to use/supply of water" through outlet pipe (7), the water level goes downwards and rubber seal (26) moves out of the hole (25) due to counterbalance of vacuum. Thus this tank never overflows in any condition.
