Description

Technical Field

[0001] The utility model relates to the technical field related to secondary water supply, in particular to a segmented pressure control mechanism for secondary water supply. Background Art

[0002] Secondary water supply refers to the form in which units or individuals store and pressurize urban public water supply or self-built facilities water supply, and then supply it to users or for their own use through pipelines. Secondary water supply is mainly established to compensate for the lack of pressure in municipal water supply pipelines and to ensure water supply for people living and working in high-rise areas.

[0003] When storing tap water, the secondary water supply generally uses a water storage tank to store water. However, when the water level in the current water storage tank is high, the pressure can only be relieved manually to discharge the tap water that is higher than the warning water level. This method is prone to untimely pressure relief. For this reason, technical personnel in this field have proposed a segmented pressure control mechanism for secondary water supply to solve the problems raised in the above background.

DETAILED DESCRIPTION

[0016] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0017] Example 1: Please refer to Figure 1A segmented pressure control mechanism for secondary water supply comprises a water storage tank 1, wherein the water storage tank 1 is divided into a water storage chamber 102 and a pressure relief chamber 103 by a partition 101, a main water inlet pipe 2 is installed at the top of the water storage chamber 102, a first water outlet pipe 3 is connected to the bottom of the water storage chamber 102, a second water outlet pipe 4 is installed at the bottom of the pressure relief chamber 103, the first water outlet pipe 3 and the second water outlet pipe 4 are both connected to the main water outlet pipe 5, a pressure relief pipe 8 is installed at the top of the partition 101, and the two ends of the pressure relief pipe 8 are respectively connected to the water storage chamber 102 and the pressure relief chamber 103, and the inner wall of the pressure relief chamber 103 is provided with a pressure relief pipe 8. A make-up water pump 9 is installed, the inlet end of the make-up water pump 9 is connected to one end of a first water pipe 10, the other end of the first water pipe 10 extends to the bottom of a pressure relief chamber 103, the outlet end of the make-up water pump 9 is connected to one end of a second water pipe 11, the other end of the second water pipe 11 passes through a partition 101 and extends to the top of the water storage chamber 102, a first water level monitor 6 is installed in the water storage chamber 102, and a second water level monitor 7 is installed in the pressure relief chamber 103, the first water level monitor 6 and the second water level monitor 7 are both selected from rod-type water level monitoring devices in the prior art.

[0018] See also Figure 1 , Figure 3 The first water outlet pipe 3 is equipped with a first water pump 301 and a first control valve 302, and the second water outlet pipe 4 is equipped with a second water pump 401 and a second control valve 402. When the pressure relief chamber 103 needs to discharge water, the first control valve 302 and the first water pump 301 are closed. When water is supplied through the water storage chamber 102, the second control valve 402 and the second water pump 401 are in a closed state.

[0019] Example 2: See Figure 1 , Figure 2 On the basis of the first embodiment, a sealing plate 801 is provided in the middle of the inner cavity of the pressure relief pipe 8, and the top of the sealing plate 801 is rotatably connected to the top of the pressure relief pipe 8 through a connecting shaft 802. A baffle 803 is fixedly connected to the inner bottom surface of the pressure relief pipe 8, and the baffle 803 is arranged on the side of the bottom end of the sealing plate 801. The baffle 803 is arranged close to the water storage chamber 102. Through this arrangement, the sealing plate 801 can only move in the direction of the pressure relief chamber 103, thereby avoiding backflow of the water storage chamber 102 when water is discharged through the pressure relief pipe 8.

[0020] See also Figure 1 The volume of the pressure relief chamber 103 is set to one third of the volume of the water storage chamber 102, ensuring that the pressure relief chamber 103 has a certain accommodating function while not occupying too much water storage space of the water storage chamber 102.

[0021] Working principle: When in use, water is injected into the water storage chamber 102 through the main water inlet pipe 2. When the water storage chamber 102 is used for water supply, the second control valve 402 and the second water delivery pump 401 are closed, and the first control valve 302 and the first water delivery pump 301 are started. The water in the water storage chamber 102 enters the main water outlet pipe 5 through the first water outlet pipe 3, and then the water is delivered to the water use area through the main water outlet pipe 5. When there is too much water in the water storage chamber 102, the excess water is discharged to the pressure relief chamber 103 through the pressure relief pipe 8 for storage. When the second water level monitor 7 detects that the water level in the pressure relief chamber 103 is high, the first control valve 302 and the first water delivery pump 301 are closed. The valve 302 and the first water pump 301 are started, and the second control valve 402 and the second water pump 401 are started. At this time, water is supplied to the main water outlet pipe 5 through the pressure relief chamber 103. When the water level in the pressure relief chamber 103 drops to a level sufficient to meet the pressure relief and drainage capacity of the water storage chamber 102, the water supply work of the water storage chamber 102 is restored. When the first water level monitor 6 detects that the water level in the water storage chamber 102 is low, the replenishing water pump 9 is started, and the water in the pressure relief chamber 103 is replenished into the water storage chamber 102 in cooperation with the first water pipe 10 and the second water pipe 11, so as to ensure the stability of the water supply pressure of the water storage chamber 102.
