Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and illustrate, by way of illustration only, the basic structure of the invention, and which therefore show only the constituents relevant to the invention.

As shown in fig. 1, a first embodiment of the present invention provides a novel non-negative pressure water supply device for high and low areas, which comprises a water inlet pipe 10 connected to a municipal water supply network, a water inlet buffer 30, a water inlet filter 20 installed between the water inlet pipe 10 and the water inlet buffer 30, a primary pressure sensor 40 and a negative pressure suppressor 50 installed on the water inlet buffer 30, a shunt pipe 60 connected to the water outlet of the water inlet buffer 30, two water outlet manifolds 70, four pressure branch lines 80 connected between the shunt pipe 60 and the water outlet manifolds 70, four secondary pressure sensors 90 installed on the water outlet manifolds 70, and an intelligent control cabinet 100.

The inlet filter 20 is used to filter the tap water before the tap water flows into the inlet buffer 30.

The inlet buffer 30 is a tank for temporarily storing the tap water flowing from the inlet pipe 10.

The primary pressure sensor 40 is used to sense the pressure of the tap water flowing from the water inlet pipe 10 into the water inlet buffer 30.

The negative pressure suppressor 50 is used for preventing vacuum and pressure imbalance of the series pipe network when the municipal tap water inflow is smaller than the water flow of a user. When the flow of tap water is sufficient and the water level in the water inlet buffer 30 rises, the negative pressure suppressor 50 breathes out air; when the water inlet buffer 30 is full of water, the negative pressure suppressor 50 is in a closed state; when municipal water inflow is smaller than water flow of users in a water consumption peak period, the water level in the water inlet buffer 30 is lowered due to insufficient water supply, the negative pressure suppressor 50 starts to suck air, and at the moment, the pressure in the water inlet buffer 30 is atmospheric pressure, so that negative pressure is suppressed.

The bypass pipe 60 is used to bypass the tap water flowing out of the water inlet buffer 30.

Each pressure branch 80 includes two butterfly valves 82, a water pump 86, and a check valve 88. The water pump 86 is used to pressurize the tap water entering the residential area. The water inlet end of the water pump 86 is connected with the water outlet of the shunt pipe 60 through one of the butterfly valves 82; the water outlet end of the water pump 86 is connected with the check valve 88 and the other butterfly valve 82 in turn, and is connected with the water inlet of the water outlet main 70.

Optionally, each pressure branch 80 further comprises two rubber soft joints 84, wherein one rubber soft joint 84 is arranged between the water inlet end of the water pump 86 and the one butterfly valve 82, and the other rubber soft joint 84 is arranged between the check valve 88 and the other butterfly valve 82.

Each secondary pressure sensor 90 is mounted to the outlet manifold 70 and disposed adjacent to the pressurizing branch 80, and is configured to sense the pressure of the tap water entering the outlet manifold 70 after being pressurized by the water pump 86.

The two water outlet ends of the water outlet main pipe 70 positioned at the left side (the first division) are connected with two water outlet pipes 72 of the first division, and the two water outlet ends of the water outlet main pipe 70 positioned at the right side (the second division) are connected with two water outlet pipes 74 of the second division.

In this embodiment, the number of the water outlet main pipes 70 is two, which are used for supplying water to users in two partitions (partition one and partition two) of a building; each water outlet header pipe 70 is connected with two pressurizing branches 80, two secondary pressure sensors 90 and two partition one water outlet pipes 72 (or two partition two water outlet pipes 74), and can supply water for users in each partition; wherein, each subarea is reserved with one water outlet pipe for supplying water to the users of the subarea, and the other water outlet pipe is used as a standby, namely, the water outlet pipes 72 of the two subareas are used as the water outlet pipes 72, wherein, the water outlet pipe 72 of one subarea is used for supplying water to the users of the subarea, and the water outlet pipe 72 of the other subarea is used as a standby; two-zone outlet pipes 74 are also one for supplying water to users of the zone and the other for standby.

The primary pressure sensor 40, the water pump 86 and the secondary pressure sensor 90 are in communication connection with the intelligent control cabinet 100, so that the tap water pressure data sensed by the water pump 86 and the tap water pressure data sensed by the primary pressure sensor 40 and the secondary pressure sensor 90 can be transmitted to the intelligent control cabinet 100 at any time.

Municipal tap water enters the water inlet buffer 30 and is divided by the flow dividing pipe 60, one path of tap water is pressurized by the water pump 86 in the first subarea and then is discharged from the water outlet pipe 72 in the first subarea (the water outlet pipe 72 in the other subarea is used as a standby) at a certain pressure to be supplied to users in the first subarea, and the other path of tap water is pressurized by the water pump 86 in the second subarea and then is discharged from the water outlet pipe 74 in the second subarea (the water outlet pipe 74 in the other subarea is used as a standby) to be supplied to users in the.

When the water supply equipment operates, the primary pressure sensor 40 detects the pressure of tap water flowing into the water inlet buffer 30 from the water inlet pipe 10, if the pressure is higher than a starting set value, the intelligent control cabinet 100 controls the water supply equipment to be automatically started, and controls the water pump 86 to operate in a variable frequency mode by taking an inlet constant pressure value as a target. If the water inflow of the tap water is greater than the water consumption of the user, in order to keep the pressure value detected by the primary pressure sensor 40 constant, the water pump 86 is inevitably accelerated to operate, the value of the secondary pressure sensor 90 on the water outlet main pipe 70 is continuously increased, and when the set outlet constant pressure value is reached, the variable frequency operation of the water pump 86 is controlled by taking the outlet constant pressure value as a target. When the water inflow of tap water is greater than the water consumption of the user and becomes less than the water consumption of the user, the pressure value detected by the primary pressure sensor 40 is inevitably reduced, and when the pressure value is reduced to a set constant inlet pressure value, the variable frequency operation of the water pump 86 is controlled by taking the constant inlet pressure value as a target. When the running water is cut off, the running frequency of the water pump 86 is necessarily low, and when the running frequency is lower than the set running frequency, the running water is judged to be cut off, and the intelligent control cabinet 100 controls the water supply equipment to stop running.

Understandably, the number of the water outlet manifolds 70 is not limited to two and may be more so as to supply water to users in more sectors of the residential building.

The number of the water outlet main pipes 70 in the novel non-negative-pressure water supply equipment for high and low areas sharing in the second embodiment shown in fig. 2 is three, and the water outlet main pipes can supply water to users in three subareas (subarea one, subarea two and subarea three) in a residential building; the water outlet main pipe 70 corresponding to the third zone is connected with two water outlet pipes 76 of the third zone, and water can be supplied to users of the third zone.

The number of the water outlet main pipes 70 in the novel non-negative-pressure water supply equipment for high and low areas sharing in the third embodiment shown in fig. 3 is four, and the water outlet main pipes can supply water to users in four subareas (subarea one, subarea two, subarea three and subarea four) in a residential building; the water outlet main pipe 70 corresponding to the third subarea is connected with two third subarea water outlet pipes 76, so that water can be supplied to users of the third subarea; the outlet header 70 corresponding to the fourth zone is connected with two fourth zone outlet pipes 78, so that water can be supplied to the users in the fourth zone.
