FIG. 1 is a schematic structural diagram of a box-type non-negative pressure water supply system according to the present invention. As shown in fig. 1, the box type non-negative pressure water supply system includes: the device comprises a conveying pipeline 1, a municipal pipeline 2 and a user pipeline 3 are respectively communicated with two ends of the conveying pipeline 1, and a steady flow tank 4 is arranged on the conveying pipeline 1; the water tank comprises a first water tank 5 and a second water tank 6, the first water tank 5 and the second water tank 6 are respectively merged into the conveying pipeline 1 through a water tank water replenishing pipeline 7 and a water tank water outlet pipeline 8 and are connected with the flow stabilizing tank 4 in parallel; a first electromagnetic valve 9 is arranged on the water tank water replenishing pipeline 7, a second electromagnetic valve 10 is arranged on the water tank water outlet pipeline 8, and a third electromagnetic valve 11 is arranged on the conveying pipeline 1 between the flow stabilizing tank 4 and the water tank water outlet pipeline 8; and the controller 12 is connected with the first electromagnetic valve 9, the second electromagnetic valve 10 and the third electromagnetic valve 11 and controls the opening and closing of the first electromagnetic valve 12, the second electromagnetic valve 10 and the third electromagnetic valve 11.
The working principle is as follows: utilize the water tank as entire system's reserve water source, when municipal pipeline 2 pressure is not enough or anhydrous, automatic the input is used, and the supplementary water supply to guarantee the stability and the continuity of supplying water. The normal pressure-superposed water supply mode is automatically converted after the pressure of the municipal pipeline 2 is recovered, and water is stored in the water tank for automatic timing recycling, so that the water supply quality is ensured. The water tank of the invention is divided into a first water tank 5 and a second water tank 6 which are used as standby water tanks of each other, and can still meet the water supply requirement at the end of the water using peak when one of the water tanks is overhauled or cleaned; at ordinary times, the water stored in the two water tanks is supplied at the peak of water utilization alternately, so that the water in each water tank is prevented from being stored for too long time to influence the water quality.
Further, a plurality of pressure boost pipelines 13 are connected in parallel at positions on the conveying pipeline 1 behind the water tank outlet pipeline 8, a water pump 14 is arranged on each pressure boost pipeline 13, a fourth electromagnetic valve 15 is arranged on each pressure boost pipeline 13 in front of the water pump 14, a fifth electromagnetic valve 16 is arranged on each pressure boost pipeline 13 behind the water pump 14, and the water pump 14, the fourth electromagnetic valve 15 and the fifth electromagnetic valve 16 are connected with the controller 12.
The box-type non-negative pressure water supply system divides the water of the municipal pipeline 2 into two parts: one part of the water enters the water tank, and the first electromagnetic valve 9 is automatically closed after the water is full; one part of the air enters the flow stabilizing tank 4, the air in the flow stabilizing tank 4 is automatically discharged through the vacuum eliminator, and the vacuum eliminator is automatically closed after the water is full.
When municipal administration pipeline 2 pressure can satisfy the water requirement, directly supply water to user's pipeline 3 by pipeline 1, water pump 14 is out of work, make full use of municipal administration pipeline 2 original pressure. When the water consumption of the user pipeline 3 is continuously increased and the pressure of the municipal pipeline 2 can not meet the water consumption requirement, the water pump 14 starts to operate, and the rotating speed is automatically adjusted according to the water consumption to supply water at constant pressure. If the rotating speed of one water pump 14 reaches the power frequency rotating speed, the other water pump 14 can be automatically started to run in a variable frequency mode. The function of 'difference and supplement' is realized. During the peak period of water use, if the flow of the water pump 14 is larger than that of the municipal pipeline 2, the water is automatically converted into the water tank, the constant-pressure frequency conversion device supplies water, and the water stored in the water tank plays a role in adjusting.
Further, a transfer pipeline 17 is connected between the first water tank 5 and the second water tank 6, and a sixth electromagnetic valve 18 is arranged on the transfer pipeline 17. When the first water tank 5 needs to be overhauled or cleaned, the water stored in the first water tank 5 is used up at the next water using peak; or the water in the second water tank 6 is exhausted at the previous water peak, and then the sixth solenoid valve 18 is opened to transfer the water in the first water tank 5 to the second water tank 6.

Further, the water tank includes a ball float valve 21, an air vent 22 and a sewage pipe 23 connected to the tank body, and a level gauge 24 provided in the tank body, the ball float valve 21 and the level gauge 24 being connected to the controller 12. The ball float valve 21 is connected with the water tank water replenishing pipeline 7, and in the water replenishing process, when the water level in the water tank rises, the ball float rises by buoyancy and slowly closes the ball float valve, so that the water tank closes the water replenishing pipeline 7. The vent 22 is disposed on the top of the water tank and is connected to the external atmosphere to maintain the air pressure balance of the water tank. The liquid level meter 24 is disposed in the water tank for measuring the water level of the water tank, connected to the controller 12, and feeds back a water level signal to the controller 12. The sewage discharge pipeline 23 is arranged at the lower side of the water tank, so that sewage after the water tank is cleaned can be discharged conveniently.
Further, a Y-shaped filter 25 is arranged on the conveying pipeline 1 close to the municipal pipeline 2 and on the water outlet pipeline 8 of the water tank. The municipal water pipe 2 may carry a lot of impurities due to long-distance pipeline transportation, and the Y-filter 25 is required to filter out the impurities in advance and supply the water to the user pipe 3. The water tank may bring many impurities due to long-time storage and untimely cleaning, and the Y-shaped filter 25 is also required to filter and supply water to the user pipeline 3.
