The invention is mainly aimed at high-rise users, because the low-rise users do not need to supply water through the invention, but directly butt joint with a municipal water supply network, and for the low-rise users, the water supply pressure of the municipal water supply network can directly supply water to the users. For high-rise users, the water supply pressure of the municipal water supply network is not enough to supply water directly to the home, so that the water supply is assisted by a front suction pump and the like. In the invention, the main water tank is arranged at a higher position (such as an equipment room on the top of a building), the water supply pressure of a municipal water supply network is not enough to directly supply water to the height of the main water tank, the water can be supplied to the main water inlet pipe and the main water tank only by the aid of the preposed water suction pump, and then the main water tank supplies water to high-rise users. It should be noted that the "high-level users" and the "low-level users" are classified according to whether the water supply pressure of the municipal water supply network can directly supply water to the users, and those users who can directly supply water to the users only by the water supply pressure of the municipal water supply network are regarded as the low-level users, and the rest are the high-level users. Therefore, the users described hereinafter are all "high-level users" unless otherwise specified.
At ordinary times, all inner tube water holes and the outer tube water hole intercommunication that corresponds, the blowdown ball valve is in the closed condition, and outer dirty valve of arranging is in the closed condition, and the washing ball valve is in the closed condition, and the water that is supplied with by municipal water supply network this moment is extracted through the pressurization of leading suction pump, reaches main inlet tube, then gets into main water tank from each inner tube water hole, outer tube water hole.
In the non-water peak period, generally speaking, the water flowing out of the main water tank is less than the water entering the main water tank, so the water level in the main water tank can rise, the main floating block, the main ball connecting rod and the main ball blocking also rise together until the main ball blocking the top air hole at a certain moment, at the moment, the main water tank can be regarded as a section of 'thicker water pipe' between the main water inlet pipe and the main water outlet pipe, and the main water tank has no negative pressure, so the original pressure of the municipal water supply network can be fully utilized to form a closed continuous relay pressurization water supply mode, and the energy-saving effect is good.
At the peak of water consumption (such as evening and evening, many users go home to cook, have a bath and other water use operations), generally speaking, the water that flows out in the main water tank is more than the water that enters main water tank, just at this moment need the water in the main water tank to realize the flow and supply, so the water level in the main water tank can descend, main floater, main ball connecting rod and main stifled ball also descend together, until main stifled ball leaves the gas pocket, at this moment, the original pressure of municipal water supply network can lose a large part or even whole, but can ensure "the water yield is sufficient" of each user side as far as possible.
When the water tank needs to be cleaned, the switch lever is pulled to drive the driving rack to move until the blowdown ball valve is in an open state, all inner pipe water holes are all sealed by the vertical outer pipe, at the moment, water flow is not transited in the main water tank, water in the main water inlet pipe directly reaches the main water outlet pipe through the vertical inner pipe, the main water tank is inside and is completely blocked by the vertical outer pipe between the vertical inner pipe, so that the cleaning operation inside the main water tank can be independently performed, and a user side can not stop water. And then opening the sealing cover, pouring the water tank cleaning liquid into the water tank, after soaking for a period of time, opening the outer sewage discharge valve, discharging the liquid (mixed liquid of the water tank cleaning liquid and water) in the water tank, then opening the cleaning ball valve, and flushing the interior of the water tank by using the cleaning hose until the interior of the water tank is cleaned. Then, the cleaning ball valve can be closed, the sealing cover is installed back, the outer blow-down valve is closed, then the switch rod is pushed to drive the driving rack to move until all inner pipe water holes are communicated with the corresponding outer pipe water holes, and the blow-down ball valve is in a closed state.
The flow-maintaining structure comprises a vertical sliding rod 71, a vertical sliding tube 72, a vertical baffle plate 73 and a vertical ejector rod 74, wherein the main horizontal tube 21 has the same inner diameter as the main water outlet tube, the flow-maintaining structure comprises a vertical sliding rod 71, a vertical sliding tube 72, a vertical baffle plate 73 and a vertical ejector rod 74, the main floating block, the vertical sliding rod, the vertical baffle plate and the vertical ejector rod are sequentially connected from top to bottom, the lower end of the vertical sliding tube is communicated with a flow-maintaining hole 21a arranged on the main horizontal tube, a tube cavity of the vertical sliding tube and the flow-maintaining hole jointly form a sliding channel hole, the vertical baffle plate is in sliding and sealing fit with the sliding channel hole, the lower end of the vertical sliding rod is arranged in the vertical sliding tube, the diameter of the vertical ejector rod is less than one thirtieth of the inner diameter of the main horizontal tube, when the water storage amount in the main water tank is more than eighty percent of the volume of the main water tank, the lowest point of the vertical baffle plate is arranged in the main horizontal tube when the, the lower end of the vertical ejector rod is contacted with the inner wall of the main transverse section pipe.
Water cut-off is an inexhaustible topic in the field of building water supply, when water is cut off, water cannot be supplemented in the main water tank, but water remained in the main water tank can be continuously supplied to users. Preferably before resumeing the water supply, prolong the time that users can "use water" as far as possible, this just needs to carry out reasonable management and control allotment to supplying water, and will avoid some special extravagant circumstances. In the scheme, once water is cut off, the water level in the main water tank can be reduced along with the water consumption of a user, when the water storage amount in the main water tank is less than or equal to eighty-five percent of the volume of the main water tank, the lowest point of the vertical baffle plate is positioned in the main transverse pipe, and when the water storage amount in the main water tank is less than seventy-five percent of the volume of the main water tank, the lower end of the vertical ejector rod is in contact with the inner wall of the main transverse pipe (at the moment, the vertical baffle plate cannot be continuously. Therefore, the main transverse section pipe is equivalently limited by the vertical baffle plate, namely, the time that a user can use water is prolonged in a throttling mode under the premise that other conditions are not changed.
It should be noted that the present invention is primarily directed to sudden water cut-off, because if the water cut-off is controlled (there is an early notification), the user can take water in advance, and there is basically no serious water shortage problem. In addition, the water cut-off can be divided into a water cut-off type and a power cut-off type, if the water cut-off type is adopted, the preposed water suction pump cannot pump water from the municipal water supply network, so that water cannot be supplied into the main water tank, and if the water cut-off type is adopted, although water still exists in the municipal water supply network, the water supply pressure of the municipal water supply network is insufficient to supply water to the height of the main water tank (the preposed water suction pump, the post water supply pump and the like cannot work due to power cut).

As mentioned above, before the water supply is resumed, it is desirable to prolong the time that users can use water as much as possible, and to perform reasonable management and control and allocation on the water supply, and avoid some special waste situations. For example, a user turns on a faucet before or after water is cut off, but forgets to turn it off. For another example, a user may use water for a long time (which may be a nuisance at ordinary times, but may be considered a "special waste situation to some extent" during periods of water outage, and it may be desirable to control such continuous use of water). In order to solve the above or similar situations, in the scheme, when water supply (power failure) is not stopped, the annular electromagnet is electrified and magnetic, the lower magnetic ring can be attracted (the annular electromagnet is not directly contacted with the lower magnetic ring and is fixed through magnetic adsorption), and the lower magnetic ring pulls the impeller shaft through the outer connecting rod, the lower connecting rod and the inhaul cable, so that the impeller shaft cannot rotate. When water is cut off, if the water is cut off, the power supply circuit of the preposed water pump is manually cut off, or the power supply circuit of the preposed water pump is automatically (or manually) cut off by using a controller (at the moment, the preposed water pump is temporarily useless, and the water is stopped), and if the water is cut off, the power supply circuit of the preposed water pump is naturally cut off. After the power is cut off, the annular electromagnet is de-energized and has no magnetism, when a user uses water, water flow drives the guide impeller to rotate, the impeller shaft also rotates, and the inhaul cable is wound, so that the pipe sealing ball, the lower connecting rod, the outer connecting rod and the lower magnetic ring are driven to ascend. When the user continuously uses water, the lower magnetic ring continuously rises, but as long as the lower magnetic ring does not rise to the height mutually attracted with the upper magnetic ring, once the user stops using water, the lower magnetic ring can fall again under the action of gravity and finally falls to the lowest position. However, if some special situations mentioned above occur, such as before or after water cut, a user opens the faucet but forgets to close, or if a user uses water for a long time, the impeller rotates continuously and finally drives the lower magnetic ring to rise to a height that the lower magnetic ring attracts the upper magnetic ring through the pull rope, the lower magnetic ring attracts the upper magnetic ring to fix, and the pipe sealing ball seals the taper pipe, so that the user cannot use water continuously, so that if the user opens the faucet before or after water cut, but forgets to close, the water waste can be avoided, if the user uses water for a long time, the user needs to reach the position of the present invention, press the elastic rubber sealing piece with a finger, push the pipe sealing ball downwards through the vertical push rod, the lower magnetic ring leaves the upper magnetic ring, and falls under the action of gravity, and finally falls to the lowest position, after which the user can continue to use the water. Therefore, the problem that a user turns on the water faucet before or after water cut but forgets to turn off the water faucet is solved, the special condition that the user uses water for a long time is reasonably avoided, and the user can restore water supply by himself aiming at the condition of the latter, so that the water control and reminding functions are achieved, and the situation that the user cannot continue to use water is avoided. In any case, the plugging of the conical pipe by the pipe sealing ball can be released by pushing down the vertical push rod to push down the pipe sealing ball as long as necessary.
The vertical control tube is internally provided with a rod seat 825 fixed with the vertical control tube, a vertical push rod penetrates through the rod seat and is in sliding fit with the rod seat, the sliding direction of the vertical push rod is vertical, the vertical push rod penetrates through the upper end of the taper tube, the lowest point of the elastic rubber sealing sheet is positioned above the highest point of the horizontal control tube, and when the elastic rubber sealing sheet is in a horizontal state and the upper magnetic ring and the lower magnetic ring attract each other, the vertical distance between the lower end of the vertical push rod and the highest point of the sealing tube ball is smaller than 3 mm. The existence of pole socket can ensure to erect the push rod and have stable controllable motion route, erects the push rod lower extreme and seals the pipe ball interval less, does benefit to the user and pushes away to seal the pipe ball through pushing down elastic rubber mounting, erecting the push rod.
The top of the vertical control pipe is provided with a hard protection screen 87 fixed with the vertical control pipe, the hard protection screen is horizontally arranged, and when the elastic rubber sealing sheet is in a horizontal state, the distance between the elastic rubber sealing sheet and the hard protection screen is less than 20 mm. Because of water pressure, when can filling up water in the vertical accuse pipe (when not stopping water, often have such a condition), on this basis, because of water pressure, still can lead to the elasticity rubber mounting to upwards swell, in order to avoid the elasticity rubber mounting upwards to swell excessively, set up hard protection otter board, can avoid the elasticity rubber mounting excessively upwards to swell to protect the elasticity rubber mounting. When the elastic rubber sealing sheet and the vertical push rod need to be pressed down to push the tube sealing ball, fingers penetrate through meshes of the hard protection screen plate to press down the elastic rubber sealing sheet and the vertical push rod.
