As described above, the present invention is directed to high-rise users who can supply water directly to their homes by the water supply pressure of the municipal water supply network, but who cannot supply water directly to their homes by the pressure of the water supply network, and therefore, the water supply needs to be assisted by additional pressurizing equipment such as a pressurizing pump. 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 home, and the users who can directly supply water to the home only by the water supply pressure of the municipal water supply network are all regarded as the low-level users, and the rest are the high-level users. Therefore, in the following explanation, the "user" refers to the "upper layer user" unless particularly emphasized.
The upper part in the surge tank stores air, the lower part in the surge tank stores water, and the water in the surge tank is communicated with the water in the main water supply pipe, and the air in the surge tank is compressed to a certain degree due to water pressure. During normal water supply, municipal water supply pipe network supplies water, and the supplementary pressurization of pressurization suction pump is with the water suction water storage tank (the water storage tank can set up the higher position of water end than high-rise user usually), again through each user's pipe of mains supply input to the realization is to user's water supply. When the water pressure in the main water supply pipe suddenly appears great change, if the water pressure is the increase, then some water in the main water supply pipe can get into the surge tank through the surge connecting pipe, the air in the surge tank is further compressed, thereby can form the buffering, protect the main water supply pipe, and can avoid the water pressure of user side to sharply increase suddenly, if the water pressure reduces, some water in the surge tank can get into the main water supply pipe through the surge connecting pipe, the air in the surge tank is reduced by the compression degree, also can realize the protection to the main water supply pipe, reduce the main water supply pipe because of the negative effects that water hammer phenomenon received.
When the water is supplied, if the water amount in the water storage tank is more than fifty percent of the volume of the water storage tank, the pressure control valve ball blocks the pressure control air hole, and at the moment, the water storage tank can be regarded as a section of thicker water pipe between the pressurization water pump and the main water supply pipe, so the water pressure loss of water supply is smaller, the original pressure of a municipal water supply network can be fully utilized, and the pressurization water pump is used for forming a closed continuous relay pressurization water supply mode.
At the water peak, generally speaking, the water that the water storage tank flows is more than the water that gets into the water storage tank, at this moment just need the water of storing in the water storage tank to realize the flow and supply, so the water level in the water storage tank can descend, if the water level in the water storage tank descends all the time, then a certain moment begins, the accuse is pressed the body, accuse pressure connecting rod and accuse pressure valve ball also descend together (the water yield is less than or equal to fifty percent of water storage tank volume in the water storage tank), accuse pressure valve ball leaves accuse pressure 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 of each user end is sufficient" as far as possible, the relative stability of flow when the.
After the non-water peak period is reached, the water flowing out of the water storage tank is less than the water entering the water storage tank, so the water level in the water storage tank can rise, the pressure control floating body, the pressure control connecting rod and the pressure control valve ball also rise together, and the pressure control air hole is blocked by the pressure control valve ball again until a certain moment.
Be equipped with liquid retaining float valve structure 22 in the surge tank, liquid retaining float valve structure includes liquid retaining float 221, liquid retaining connecting rod 222, locate liquid retaining baffle 223 in the surge tank and be used for plugging up the liquid retaining valve ball 224 in jar surge hole, liquid retaining valve ball, liquid retaining connecting rod and liquid retaining float connect gradually from bottom to top, liquid retaining baffle is in liquid retaining float top, liquid retaining float and surge tank sliding connection, liquid retaining float slip direction is vertical, when the water yield is greater than the fifty percent of surge tank volume in the surge tank, liquid retaining float contact liquid retaining baffle, jar surge hole and surge tank inside intercommunication, when the water yield is less than or equal to the fifty percent of surge tank volume in the surge tank, jar surge hole is plugged up to the surge valve ball.
The water storage tanks are regularly cleaned and maintained. Wash the maintenance in-process, the water storage tank, water in the main water supply pipe can be drained to the greatest extent, so water in the surge tank also can be arranged to minimum water level (stop up a jar steady voltage hole until steady voltage valve ball), resume normal water supply after, give "quantitative reasonable retaining" in the surge tank once more and just become the problem, because in practical application, should not seal a very large amount of air relatively in the surge tank, this is because, if seal a very large amount of air relatively, the water yield in the surge tank is just relatively few so, the regulation of surge tank, the buffering, protective capacities can be relatively poor (although the air in the surge tank is enough, but the water yield that can supply to flow in order to carry out main water supply pipe pressure adjustment is not enough). Therefore, after water in the main water supply pipe enters the pressure stabilizing tank and forms a water seal, a relatively large amount of air is still reserved at the upper part in the pressure stabilizing tank, and the air in the pressure stabilizing tank needs to be continuously discharged partially to achieve a more reasonable state.
In this scheme, after the water supply main pipe provided partly water and got into the surge tank, at initial stage, the air in the surge tank can be followed and is protected gas check valve and discharge, when water yield was greater than seventy-five percent of surge tank volume in the surge tank, the gas protection gas pocket was stopped up to the valve plate that keeps gas, and afterwards, water just can compress the air on upper portion in the surge tank after continuing to get into the surge tank, finally reaches the state before the outage again.
The water storage tank is internally provided with a pressure control supporting body 12 for supporting the pressure control floating body, the pressure control supporting body is positioned below the pressure control floating body, when the water amount in the water storage tank is greater than fifty percent of the volume of the water storage tank, the pressure control floating body is separated from the pressure control supporting body, when the water amount in the water storage tank is less than or equal to fifty percent of the volume of the water storage tank, the pressure control floating body is contacted with the pressure control supporting body, the pressure stabilizing tank is internally provided with an air-retaining supporting body 23 for supporting the air-retaining floating body, the air-retaining supporting body is positioned below the air-retaining floating body, when the water amount in the pressure stabilizing tank is greater than seventy five percent of the volume of the pressure stabilizing tank, the air-retaining floating body is separated from the air-retaining supporting body, and when the water amount. The pressure control floating body and the air-retention floating body can move, and limit structures (a pressure control supporting body and an air-retention supporting body) are specially arranged for reducing the moving distance of the pressure control floating body and the air-retention floating body, reducing the abrasion and prolonging the service life of the pressure control floating body and the air-retention floating body, so that the pressure control floating body and the air-retention floating body can be protected.
The surge tank below is equipped with emergent even pipe 52, is equipped with the emergent hole 52a of pipe on the main water supply pipe lateral wall, and surge tank bottom is equipped with jar emergent hole 52b, and emergent even pipe upper end is equipped with the emergent hole of jar, and emergent even pipe lower extreme is equipped with emergency solenoid valve 53 on the emergent even pipe, and emergency solenoid valve electrified normal close, emergency solenoid valve power-off normally open. Since high-rise water use is involved, water cut-off is a problem that has to be addressed. After the water supply is cut off, the time that users can use the water is preferably prolonged as much as possible before the water supply is resumed. In this scheme, as long as emergent solenoid valve loses electricity, emergent connecting pipe is a route so, and the water in the surge tank also can supply for users as emergent water source so. Here, a point is mentioned, that is, water cut can be divided into 'water cut-off type water cut-off' and 'power cut-off type water cut-off'; if the water storage tank is the former, the pressurizing water pump cannot pump water from the municipal water supply network, so that water cannot be continuously supplied into the water storage tank; in the latter case, although there is water supply in the municipal water supply pipe network, the water supply pressure of the municipal water supply pipe network is not sufficient to directly supply water to the water storage tank. In practical application, if the emergency electromagnetic valve is powered off due to power failure, the pressure water pump, the emergency electromagnetic valve and other electric equipment lose working significance and are also powered off or power off, wherein the pressure water pump, the emergency electromagnetic valve and other electric equipment can be manually powered off or power off, and the pressure water pump and the emergency electromagnetic valve can be powered off or power off automatically through a conventional controller.
The main water outlet hole and the main water supply pipe are coaxially arranged, the axis of the main water supply hole is horizontal, the aperture of the main water supply hole is equal to the inner diameter of the main water outlet pipe, the inner bottom surface of the water storage tank is horizontal, and the lowest point of the main water supply hole is as high as the inner bottom surface of the water storage tank.
The user pipe communicates with the main water supply pipe through an intermediate pipe, which includes a horizontal control pipe 61 butted with the main water supply pipe and a vertical control pipe 62 butted with the user pipe, in one intermediate pipe: an inner shaft bracket 611 and a plurality of guide vanes 612 are arranged in the horizontal control pipe, a side hole 62a communicated with one end of the horizontal control pipe is arranged on the side wall of the vertical control pipe, an outer shaft bracket 621, a pull rope 622, a taper pipe 63, a pipe sealing ball 631 capable of sealing the taper pipe and a lower magnetic ring 64 arranged below the pipe sealing ball are arranged in the vertical control pipe, an impeller shaft 65 which is coaxially arranged with the horizontal control pipe and is rotatably connected with the inner shaft bracket is arranged on the inner shaft bracket, the impeller shaft passes through the side hole and is rotatably connected with the outer shaft bracket, the guide vanes are coaxially fixed with the impeller shaft, the guide direction of the guide vanes is from a main water supply pipe to the side hole through the guide vanes, the inner diameter of the taper pipe is sequentially increased from top to bottom, a sealing sleeve 632 which is hermetically fixed with the inner wall of the vertical control pipe is arranged at the lower end of the taper pipe, an upper magnetic ring 66 which is arranged above the lower, the other end of the inhaul cable is connected with a pipe sealing ball, the bottom of the pipe sealing ball is provided with a lower connecting rod 633, the lower connecting rod is connected with a lower magnetic ring through an outer connecting rod 634, the lower magnetic ring is in sliding fit with a vertical control pipe, an elastic rubber sealing sheet 623 fixed with the inner side wall of the vertical control pipe in a sealing mode is arranged in the vertical control pipe, a vertical push rod 624 used for pushing the pipe sealing ball is arranged in the vertical control pipe, the upper end of the vertical push rod is connected with the elastic rubber sealing sheet, when the pipe sealing ball is located below the conical pipe, the upper magnetic ring is separated from the lower magnetic ring, and when the upper magnetic ring and the lower magnetic ring attract;
in one intermediate conduit: the annular electromagnet capable of attracting the lower magnetic ring is sleeved outside the vertical control tube and connected in series in a power supply circuit of the pressurizing water pump, the annular electromagnet is electrified and magnetized, the annular electromagnet is not electrified and magnetized, when the lower magnetic ring falls to the lowest position, the top surface of the annular electromagnet and the top surface of the lower magnetic ring are located in the same horizontal plane, and the bottom surface of the annular electromagnet and the bottom surface of the lower magnetic ring are located in the same horizontal plane.
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. As another example, a user may use water for a long period of time (which may be a nuisance during normal 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 continued 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 the water supply is stopped, if the water supply is stopped in the water stop mode, the power supply circuit of the pressurizing water pump should be manually cut off, or the power supply circuit of the pressurizing water pump should be automatically cut off by using the controller (at this time, the pressurizing water pump is temporarily useless, and the water supply should be stopped), and if the water supply is stopped in the power cut mode, the power supply circuit of the pressurizing 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. If some special conditions occur, such as before or after water supply is stopped, a user turns on the faucet but forgets to turn off the faucet, and if a certain user uses water for a long time, the impeller continuously rotates and finally drives the lower magnetic ring to rise to a height which is mutually attracted with the upper magnetic ring through the inhaul cable, finally the lower magnetic ring and the upper magnetic ring are mutually attracted and fixed, and the conical pipe is sealed by the pipe sealing ball, so that the user cannot continue to use water. Thus, if the cause is the condition that the user turns on the water tap before or after water cut but forgets to turn off, the water can be prevented from being wasted continuously; if the cause is the situation that the user always uses water for a long time, the user needs to reach the position of the water-saving water dispenser, the user presses down the elastic rubber sealing piece with fingers, so that the pipe sealing ball is pushed down through the vertical push rod, the lower magnetic ring leaves the upper magnetic ring. 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 625 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 tube sealing 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 plate 67 fixed with the vertical control pipe, the hard protection screen plate is horizontally arranged, and when the elastic rubber sealing piece is in a horizontal state, the distance between the elastic rubber sealing piece and the hard protection screen plate 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.
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.
