Water retention capacity - entire retentiveness of the sewer hole or water gully pit of sewer system also affects such situation. The water retention capacity for rainwater collection remains unused in known inspection chambers or gullies, Therefore an excess water drains off higher terrain and higher area - higher part of sewer system, to the lower one and floods it, what can occurred especially at highly urbanized areas.
There are known check valves that contain a locking float. The known valves are mounted within pressure piping such as water-supply system. The valve functioning bases on locking the entire pipe in cross-section during change of flow direction that prevents from continual water refluxing because the pipe is locked. The known check valves are characterized with complex structure, the shape of the locking element is usually planar and works by being pressed with a spring. The main disadvantage of the known check valves is that they only allow to prevent from typical fluid backwater - water refluxing - in various types of a pipeline system.
Therefore the object of the invention is to provide the solution that not only protects from backwater situation but protect from other caused of water overfill of sewer system. The invention enables a retention of excess water especially within upper parts of sewer system that are located in a higher terrain as long as lower parts of the sewer system that are located in a lower terrain are prepared to receive excess water from a higher terrain. In particular, the invention solves the problem by using of entire water retention capacity of a gravitationally functioning sewer system comprising sewer hole, water gully and pipeline system connecting them. The subsequent object of the invention is to provide solution that enables to protect from damaging influence of an excessive pressure of water.
Thus according to the invention, check valve for using with water sewer system comprises a locking float within an mean in a form of an enclosure for the locking float, an extending item for a pipe for making an elongation of an outlet of the pipe into a gully or into a sewer hole. Within the enclosure the locking float is movably encompassed while the size of the locking float is adjusted to the outlet of the pipe diameter such that the size of the locking float in cross-section exceeds the inside diameter of the outlet of the pipe into the gully or into the sewer hole.
Preferably, the locking float is shaped spherically.
Preferably, the enclosure is formed into cage or nest shape with bent rods.
Preferably, the diameters of the extending item and the outlet of the pipe are equal.
To solved the problem, the present invention also provides check valve for using with water sewer system that comprises a locking float within a mean in a form of an enclosure for the locking float, an extending item for a pipe for making an elongation of an outlet of the pipe into a gully or into a sewer hole. The enclosure is mounted to the extending item and within the enclosure the locking float or a non-buoyant locking item is movably encompassed and the size of the locking float or the non-buoyant locking item is adjusted to the outlet of the pipe diameter such that the size of the locking float or the non-buoyant locking element in cross-section exceeds the inside diameter of the outlet of the pipe into the gully or into the sewer hole. The locking float or the non-buoyant locking element is connected to the second float, which is located upper towards the outlet of the pipe into the gully or into the sewer hole, wherein the diameter of the second float in cross-section is larger, equal or smaller in comparison to the inside diameter of the outlet of the pipe into the gully or into the sewer hole.
Preferably, the locking float or the non-buoyant locking element is shaped spherically. Preferably, the enclosure is formed into cage or nest shape with bent rods.
Preferably, the diameters of the extending item and the outlet of the pipe are equal. Preferably, the second float is movably attached to the wall of the gully or wall of the sewer hole.
To solved the problem, the present invention also provides the method for water flow regulation within sewer system between pipe, sewer hole and/or gully, the method comprising the step of: - mounting of an extending item for making an elongation of the outlet of the pipe into the sewer hole or the gully; - mounting of an enclosure to the extending item to be located below the outlet of the pipe; - positioning a locking float to be movably encompassed by the enclosure wherein the size of the locking float is adjusted to the outlet of the pipe diameter in such a way that the size of the locking float (in cross-section exceeds the inside diameter of the outlet of the pipe into the sewer hole or into the gully. Whilst the level of water that is being impounded within the interior of the sewer hole or the gully is rising, the locking float is being moved upwards by buoyancy toward the outlet of the pipe into the sewer hole or the gully until the outlet into the sewer hole or the gully is locked by the locking float. The moving trajectory of the locking float is determined by limitation of the enclosure.
To solved the problem, the present invention also provides the method for water flow regulation within sewer system between pipe, sewer hole and/or gully, the method comprising the step of: - mounting of an extending item for making an elongation of an outlet of the pipe into the sewer hole or into the gully; - mounting of an enclosure to the extending item to be located below the outlet of the pipe; - positioning a locking float or a non-buoyant locking item to be movably encompassed by the enclosure wherein; - connecting the locking float or the non-buoyant locking item to a second float, which is located upper towards the outlet of the pipe into the sewer hole or into the gully.

The diameter of the second float in cross-section is larger, equal or smaller in comparison to the inside diameter of the outlet of the pipe into the sewer hole or into the gully. Whilst the level of water that is being impounded within the interior of the sewer hole and/or the gully is rising, impacting its buoyancy on the second float and the locking float or the non-buoyant locking element such that the locking float or the non-buoyant locking element is being moved upwards toward the outlet of the pipe into the sewer hole or the gully until the outlet into the sewer hole or the gully is locked by the locking float or the non-buoyant locking element. The moving trajectory is determined by limitation of the enclosure and the locking float or the non-buoyant locking item is being pulled by the second float movement.
Preferably, the second float is movably attached to the wall of the sewer hole or the gully.
The check valve and the method according to the invention enables to provide protection against so called "backwater" - water refluxing through pipe that occurred not only during flood, as well as flood protection and deluge protection by its ability to regulate water flow between pipeline, sewer hole and/or water gully. The check valve according to the invention works as per automatics and hydraulics rules. The core of the system is based on self-acting locking mean with function of prevention from an excess water flow from sewer pipeline into a sewer hole and/or a water gully during flood, deluge or backwater occurrence. The essential part of the invention is the locking float that is constructed and located according to the invention such that it floats correspondingly to water level inside a sewer hole or a water gully.
The invention is usable for any type of sewerage, especially for gravity sewers, rainwater sewer, combined sewage system, separate sewage system, partially separate sewage system, mixed sewage system.
The check valve and the method for water flow regulation between piping and sewer hole and/or water gully according to the invention solve not only the problem of backwater occurrence but additionally have deluge or flood prevention function. The system bases on the check valve according to invention protects against excessive pressure of water developing within a water sewer system by using an entire water retention capacity of individual sewer holes or water gullies. The domino effect is in use here that relates to filling with water of sewer holes and/or water gullies starting from the lowest part of terrain and area. Equipped with the according to invention check valve, sewer holes and/or water gullies are, by an excessive water flow, sequentially filled and locked as the consequence of the check valve functioning. The water sewer system is thereby divided into separate parts that makes a general effect of diminished pressure of water occurrence and water sewer system is thereby significantly less exposed to a damaging influence of uncontrolled excessive pressure of water. When a level of water within the water sewer system declines then sequentially the check valves located from bottom to top means from lower to higher parts of the sewer system become unlocked, that provides the controlled run off of water.
During heavy rainfall that can lead to flood or deluge, the invention protects against water overfill and regurgitation of water from a sewer hole and/or a water gully that takes place especially in lower parts of a water sewer system. The invention enables to prevent from the situation above by making usable the entire retentiveness of sewer holes, water gullies and piping, especially including those located in higher parts of water sewer system. The invention enables lower located parts of a water sewer system to dehydrate and only when the lower parts are dehydrated then sequentially the locking elements of the check valves become unlocked in order from the lower located lower to the ones in the higher parts of the sewer system, that provides the controlled runoff of water.
The check valve and the method according to the invention are constructed to function as substitute for storage reservoir - impounding reservoir - within parts of the sewer system - sewer holes, water gullies and pipeline system between them since they enable to fill with water not only the parts of a water sewer system that cumulates water locally, but also the parts which remains unfilled and thereby the water sewer system is enabled to be filled with water not locally but much more widely. The invention enables, in situation when the capacity of a particular sewerage is exceeded, to drain an excess water through alternative ways and protect against excessive water accumulation within the lower parts of a water sewer system by a regular runoff of water provided within the entire water sewer system and not only to the lowest located areas. The invention enables an effective and fully impounding water reservoir easily to be built.
The invention is shown in more details in the examples and drawings wherein Fig, 1 shows a scheme of a sewer hole or a water gully that the check valve according to the embodiment of invention is mounted in, while Fig 2 shows a scheme of a sewer hole or a water gully that the check valve, according to following embodiment of the invention, that makes the floating system is mounted in.
Example
A check valve 3 suitable for using with a water sewer system: gravity sewers, especially stormwater sewer, comprises a locking float 4 that is spherically shaped with diameter of 170 mm which is larger than inside diameter of an outlet of a pipe 1 into a sewer hole 2 and/or a water gully 2, in order to has locking function. The inside diameter of the outlet of the pipe is 150 mm. The sewer hole also means an inspection chamber: well with an access opening into its, while the gully also means a rainwater or stormwater gully pit. The check valve comprises also an enclosure 5 - holding and an extending element la that is mounted for making an elongation of the outlet of the pipe. The locking float 4 is movably encompassed within the enclosure 5 that is molded into a cage form or nest with five metal rods which diameter is 3 mm and are bent into semicircular shape. The rods are not connected to each other at the bottom of the enclosure 5 so that any possible filths which are present in the sewer hole and/or the gully are not being held and collected within the enclosure 5 and therefore drain off together with water. The preferable number of rods is 3-6.
The using of larger number of floats is optional as well as the combinations of additional float with a non-buoyant item or the locking float to constitute the floating system of the check valve 3. A mentioned above, the size of the locking float 6 or the non-buoyant item 6 for locking is adjusted to the outlet of the pipe 1 diameter. The diameter of the second float 4 that is located upper towards the outlet of the pipe 1 into the sewer hole 2 or the water gully 2 in cross-section is larger, equal or smaller in comparison to the inside diameter of the outlet of the pipe 1 into the sewer hole 2 and/or the water gully 2.
According to the method, the check valve 3, as described above, is mounted within the outlet of a pipe into the sewer hole 2 and/or the water gully 2. The method for water flow regulation between pipeline system in particular inlet piping and the sewer hole and/or the water gully comprises the steps of mounting of the extending element la in a way for making an elongation of the outlet of the pipe 1 into the sewer hole 2 and/or the water gully 2, and then mounting of the enclosure 5 to the extending element la to be located below the outlet of the pipe 1 while after the enclosure mounting positioning the locking float 4 within in a way to be movably encompassed within the enclosure 5. The flow of water into the sewer hole 2 and/or the gully 2 is stopped due to the check valve being locked that is provided by the locking float 4 functioning conjunctively with the level of water that rises inside the sewer hole 2 or the water gully 2. Whilst the level of water that is being impounded within the interior of the sewer hole 2 or the gully 2 is rising, the stopping of water is performed because the locking float 4 is being moved upwards by force of buoyancy toward the outlet of the pipe 1 into the sewer hole 2 or the gully 2 until the outlet into the sewer hole 2 or the gully 2 is locked by the locking float 4. The upwards moving trajector of the locking float 4 is determined by limitation of the enclosure 5. The method therefore provides protection from water overfill and regurgitation from the sewer hole and/or the water gully because flow of water is cut off by the locking float that brings about locking the outlet into the sewer hole and or the water gully.
There is an additional option for any types of seals to be mounted within the sewer system. The way of a non-return valve and the end of an outlet of pipe connection is known in the art including band using connection, gluing, torque using connection, rawl using connection, self-pressing connection, counter tie, straining beam, snap, clamp, band.
In other embodiment of the invention, with the floating system, the method comprises the additional step of positioning the locking float 6 or the non-buoyant locking item 6 below the outlet of the pipe 1 into the sewer hole and/or the gully and connecting it to the second float 4 that is located upper towards the outlet of the pipe 1 into the sewer hole 2 and/or the gully 2. The second float is movably attached to the wall of the gully or wall of the sewer hole. Such connection - the floating system, according to the embodiment of the invention, enables to increase a force of the check valve to protect from water flow from a sewer hole or water gully, to increase a power to dam a water flow and water rising or to transfer the force to different location. As far as sewer holes are concerned, the optimal is to locate the floating system as high as possible to gain the maximal retentiveness, water retention capacity, of the sewer hole. The higher is a water level that enables to lock the outlet into the sewer system by the floating system, the larger retentiveness of the sewer hole is. The later the float is to be moved upwards the larger water retention capacity is used. Whilst the level of water that is being impounded within the interior of the sewer hole 2 or the gully 2 is rising, the impact of buoyancy is amplified by directing force of buoyancy on the second float 4 and the locking float 6 and impacting the non-buoyant locking item 6 that is performed in such way that the locking float 6 or the non-buoyant locking item 6 is being moved upwards toward the outlet of the pipe 1 into the sewer hole 2 or the water gully 2. The non-buoyant locking element 6 or, in addition to the force of buoyancy the locking float 6 is being pulled by the second float 4 movement. This is performed until the outlet into the sewer hole 2 or the gully 2 is locked by the locking float 6 or the non-buoyant locking item 6. The moving trajectory of the locking float 6 or the item non-buoyant locking 6 is determined by limitation of the enclosure 5.
