Description

Technical Field

[0001] The present application relates to the technical field of water pressure control, and in particular to a water supply pressure control device for preparing softened water. Background Art

[0002] In the process of softening water preparation, heating and removing impurities from the water flow is a very important step. The purpose is to remove minerals and other impurities in the water while ensuring the safety and quality of the water. In order to heat the water flow fully and evenly, high borosilicate glass tubes are often used to transport the water flow and heat the external high borosilicate glass tubes.

[0003] Since the water flow needs to increase pressure to supply water during the flow process, the existing water pump has uneven water supply pressure fluctuations during the water supply process. Therefore, a pressure control device is needed to regulate the water flow pressure during the water flow transportation process.

[0004] For example, a patent application with publication number CN204229254U discloses a liquid pressure regulator. This prior art realizes the function of easy installation without major modifications to existing devices through the combined design of a cylinder body and a liquid delivery pipeline. A diaphragm and a column rod are provided inside the regulator. The column rod passes through the cylinder body and the liquid delivery pipeline and is connected to the plunger. Through the coordinated action of the latch, fork-shaped positioning part, pin shaft and support rod in the adjustment mechanism, the position of the column rod can be adjusted, and then the flow rate of the plunger can be adjusted to achieve the effect of accurately adjusting the liquid pressure, which significantly improves the convenience and applicability of liquid pressure regulation.

[0005] When using the above-mentioned existing technology to adjust the liquid pressure inside the pipeline, the following problems still exist: there is already a certain basis for the method of relieving the pressure of the liquid with high pressure inside the pipeline, but when the liquid does not fill the pipeline, the instantaneous high pressure of the flowing liquid can easily lead to increased stress on the inner wall of the pipeline, which may cause damage to the inner wall of the pipeline. This problem will have an adverse effect on the service life of the pipeline in long-term use.

[0006] Although there are some technical means that can alleviate the above-mentioned problems to a certain extent, the effectiveness of existing technical means when faced with situations where the pipe is not full and the pressure rises abnormally, there is still room for improvement, especially in ensuring that the inner wall of the pipe is not subjected to excessive stress.

[0007] Based on this situation, there is still room for improvement in the existing technology for regulating and controlling the liquid pressure inside the pipeline, especially in effectively managing the stress on the inner wall of the pipeline when meeting the liquid flow under different working conditions and improving the service life of the pipeline. Summary of the invention

[0008] The present invention aims to propose a water supply pressure control device for preparing softened water under the above background, so as to better manage and control the pressure inside the pipeline, reduce potential damage to the inner wall of the pipeline, and extend the service life of the pipeline. The present invention specifically adopts the following technical scheme: a water supply pressure control device for preparing softened water, comprising a through control body, a water pressure control mechanism is arranged on the control body, and connecting circular pipes that are through the control body are installed at both ends of the control body.

[0009] The control body is provided with blocking discs and opening and closing discs for opening and closing the control body in sequence along its length direction, and the control body is divided into a liquid inlet part, a storage part and a liquid outlet part in sequence.

[0010] The water pressure control mechanism comprises: an isolation plate, which is installed inside the liquid inlet part and forms a pressure relief chamber with the blocking disc and the inner wall of the control body.

[0011] The pressure relief round block is slidably arranged on the isolation plate and automatically resets.

[0012] The yield cylinder is installed on the top of the control body and is connected with the inside of the control body.

[0013] A water discharge trough which is in continuous connection with the pressure relief chamber is provided on the blocking disc.

[0014] Preferably, the pressure relief block is slidably matched with the give-way cylinder, and a vertical rod is arranged on the top of the pressure relief block. One end of the vertical rod away from the pressure relief block passes through and is slidably arranged on the top of the give-way cylinder. The part of the vertical rod located inside the give-way cylinder is sleeved with a telescopic spring for resetting the pressure relief block. The bottom of the telescopic spring is connected to the pressure relief block, and the top of the telescopic spring is connected to the top of the give-way cylinder.

[0015] Preferably, a pressure relief pipe which is connected to the interior of the yield cylinder is arranged on the side wall thereof, and an arc plate for sealing the pressure relief pipe is installed on the pressure relief round block.

[0016] Preferably, a plurality of pressure relief pipes are evenly arranged along the length direction of the yield cylinder.

[0017] Preferably, the opening and closing disc is symmetrically mounted with support shafts extending along the length direction of the give-way cylinder, and the support shafts are rotatably mounted on the control body, and the opening and closing disc is jointly mounted on the two support shafts.

[0018] Preferably, the support shaft close to the side of the give way cylinder passes through the control body, and a driving motor for driving the opening and closing disc to rotate is installed on the corresponding support shaft, and a switch for controlling its own start and stop is installed on the driving motor.

[0019] Preferably, a clearance groove is opened inside the control body, a linkage rod is slidably arranged inside the clearance groove, a floating block is installed at one end of the linkage rod located inside the control body, and a linkage connecting rod cooperating with the switch is installed at the end of the linkage rod away from the floating block.

[0020] Preferably, an air valve for exhausting the storage part is provided through the inside of the give way groove, so as to facilitate the liquid to enter the storage part.

[0021] Preferably, the liquid inlet portion and the storage portion are connected through a connecting pipe with a U-shaped structure, a sealing rod is installed at the bottom of the pressure relief round block, and one end of the sealing rod away from the pressure relief round block is sealed and inserted into the connecting pipe.

[0022] Preferably, a liquid leakage port is provided at the bottom of the blocking disc.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. The pressure relief block and the give-way cylinder cooperate with each other: when the water pressure inside the liquid inlet is high, the pressure relief block will open, and release part of the water flow through the give-way cylinder to reduce the water pressure in the pipeline, so as to avoid the pipeline being damaged due to high pressure; the storage part handles low-flow water: when the water flow inside the liquid inlet is small, the storage part will store the water flow to increase the water flow pressure, so as to ensure that even if the water flow is small, the water flow pressure inside the pipeline can be stable, avoiding damage to the pipeline caused by sudden pressure changes.

[0024] 2. When the water pressure in the liquid inlet is too high, the pressure relief block will pass over the pressure relief pipe, allowing the water to flow out through the pressure relief pipe, thereby effectively reducing the internal water pressure of the liquid inlet, preventing the pressure relief block from traveling beyond the length of the give way cylinder, thereby preventing the telescopic spring from failing and ensuring the smoothness and integrity of the pressure relief process.

[0025] 3. The floating block designed in the present invention drives the floating block to move upward after the water inside the storage part is full. When the water accumulation in the storage part reaches a certain amount, the floating block will float up with the water and synchronously drive the linkage rod to move upward through the linkage rod, and finally start the switch, so that the drive motor is automatically turned on.

[0035] The following is combined with Figures 1 to 8 This application is described in further detail.

[0036] The embodiment of the present application discloses a water supply pressure control device for preparing softened water. By means of pressure relief and pressure storage, the water flow entering the existing pipeline can always maintain a constant pressure state to ensure the stability of the water pressure. At the same time, in order to deal with the situation where the water flow pressure is too high, we adopt a variety of different pressure relief methods. We can choose the appropriate pressure relief method according to the pressure size, accurately control the pressure, and avoid damage to the existing pipeline due to overpressure.

[0037] Embodiment 1: Reference Figures 1 to 3 A water supply pressure control device for preparing softened water comprises a through control body 1, a water pressure control mechanism 2 is arranged on the control body 1, and connecting circular pipes 3 through the control body 1 are installed at both ends.

[0038] The control body 1 is provided with a blocking disc 11 and an opening and closing disc 12 for opening and closing the control body 1 in sequence along its length direction, and the control body 1 is divided into a liquid inlet portion 13, a storage portion 14 and a liquid outlet portion 15 in sequence.

[0039] The water pressure control mechanism 2 comprises: an isolation plate 21 , which is installed inside the liquid inlet portion 13 and forms a pressure relief chamber 22 together with the blocking disc 11 and the inner wall of the control body 1 .

[0040] The pressure relief round block 23 is slidably disposed on the isolation plate 21 and automatically resets.

[0041] The clearance cylinder 24 is installed on the top of the control body 1 and is connected with the inside of the control body 1 .

[0042] The blocking disc 11 is provided with a drain groove 111 which is connected to the pressure relief chamber 22 .

[0043] The connecting circular tube 3 near the liquid inlet portion 13 is connected to the existing water tank, and a water pump is installed between the corresponding connecting circular tube 3 and the water tank to provide a power source for the flow of water, so that the water inside the existing water tank flows into the existing pipeline through the water pump, and then the connecting circular tube 3 near the liquid outlet portion 15 is connected to the existing pipeline, and then the water inside the water tank is discharged into the existing pipeline after passing through the water pump, the connecting circular tube 3, the control body 1, and the connecting circular tube 3.

[0044] During specific operation, turn on the water pump, and the water flows through the water pump and enters the liquid inlet part 13 through the connecting circular pipe 3 close to the liquid inlet part 13. At this time, the water flows gather inside the liquid inlet part 13: if the water flow pressure is large, the water inlet pressure inside the liquid inlet part 13 is high, and the pressure relief block 23 will open, that is, the pressure relief block 23 moves up and moves to the inside of the give way cylinder 24. At this time, the water flows into the pressure relief chamber 22, and the height inside the pressure relief chamber 22 gradually increases. When the water flow height inside the pressure relief chamber 22 reaches the height of the drainage trough 111, the water inside the pressure relief chamber 22 enters the storage part 14 through the drainage trough 111. At this time, the water height inside the storage part 14 gradually increases. When the water height inside the storage part 14 reaches a certain height, the opening and closing disc 12 is opened, and the water inside the storage part 14 flows through the liquid outlet 15 into the existing pipeline.

[0045] By releasing part of the water flow through the displacement cylinder 24, the water pressure in the pipeline is reduced, thus preventing the pipeline from being damaged due to a large pressure; thus, the water pressure flowing into the existing pipeline is kept constant in the subsequent process.

[0046] When the water flow entering the liquid inlet 13 is small, the water flow gathers inside the liquid inlet 13. When it reaches a certain height, the water flow has a certain pressure at this time, and the water pressure squeezes the pressure relief round block 23 to move upward. The storage part 14 processes the low-flow water: when the water flow inside the liquid inlet 13 is small, the storage part 14 stores the water flow to increase the water flow pressure, and moves it to the inside of the give way cylinder 24. At this time, the water flows into the pressure relief chamber 22, and the height inside the pressure relief chamber 22 gradually increases. When the water flow height inside the pressure relief chamber 22 reaches the height of the drainage trough 111, the water inside the pressure relief chamber 22 enters the storage part 14 through the drainage trough 111. At this time, the water body height inside the storage part 14 gradually increases. When the water body height inside the storage part 14 reaches a certain height, the opening and closing disc 12 is opened, and the water flow inside the storage part 14 enters the existing pipeline through the liquid outlet 15.

[0047] This ensures that even if the water flow is small, the storage unit 14 can pressurize the small water flow, so that the water pressure flowing from the inside of the control body 1 to the inside of the existing pipeline is always in a stable pressure state, avoiding damage to the pipeline caused by sudden pressure changes.

[0048] Through the above-mentioned method, no matter whether the water pressure entering the liquid inlet part 13 is large or small, the water pressure control mechanism 2 and the storage part 14 cooperate with each other to ensure that the water flowing into the existing pipeline is always in a constant pressure state, thereby reducing the possibility of damage to the inner wall of the existing pipeline caused by the fluctuation of water pressure. That is, through the pressure relief mechanism: the influx of high-pressure water flow is controlled to protect the existing pipeline from damage; through the pressure storage mechanism: a stable low-pressure water flow is maintained, the risk brought by pressure fluctuations in the existing pipeline is reduced, and the service life of the existing pipeline is extended.

[0049] Reference Figure 4 The pressure relief block 23 is slidably matched with the giving way cylinder 24, and a vertical rod 231 is arranged on the top of the pressure relief block 23. One end of the vertical rod 231 away from the pressure relief block 23 penetrates and is slidably arranged on the top of the giving way cylinder 24. The part of the vertical rod 231 located inside the giving way cylinder 24 is sleeved with a telescopic spring 232 for resetting the pressure relief block 23. The bottom of the telescopic spring 232 is connected to the pressure relief block 23, and the top of the telescopic spring 232 is connected to the top of the giving way cylinder 24.

[0050] During specific operation, when the water flow pressure inside the liquid inlet part 13 is relatively high, the drain trough 111 cannot discharge the water flow inside the pressure relief chamber 22 to the storage part 14 in time. At this time, the pressure relief block 23 drives the vertical rod 231 to move upward during the upward movement, and the telescopic spring 232 is compressed synchronously. The gap between the bottom of the pressure relief block 23 and the top of the pressure relief chamber 22 can make way for the water flow inside the pressure relief chamber 22 to relieve the pressure, so that the excess water flow inside the control body 1 enters the gap between the bottom of the pressure relief block 23 and the top of the pressure relief chamber 22, thereby playing a pressure relief role. When the water flow pressure is stable, the water pressure inside the control body 1 is reduced, and the telescopic spring 232 is reset and synchronously drives the pressure relief block 23 to reset, and then the telescopic spring 232 and the vertical rod 231 cooperate with each other to perform adaptive pressure relief processing on the water flow with relatively high pressure, thereby avoiding the possibility of damage to the inner wall of the existing pipeline caused by excessive pressure on the existing pipeline.

[0051] A limiting protrusion is provided on the top of the vertical rod 231 , which can limit the vertical rod 231 at the starting position and prevent the vertical rod 231 from falling into the inside of the yield cylinder 24 .

[0052] Reference Figure 4 If the water flow pressure is too high and the length of the yield cylinder 24 is insufficient for the pressure relief block 23 to move, in order to protect the telescopic spring 232 and prevent the displacement of the pressure relief block 23 from exceeding the length change of the telescopic spring 232 to cause damage to the telescopic spring 232, and to ensure that the water flow at the liquid inlet 13 can be smoothly depressurized, the pressure relief pipe 233 is provided in the present invention to relieve the pressure of the water flow with excessive water pressure. Specifically, the side wall of the yield cylinder 24 is provided with a pressure relief pipe 233 that is connected to the interior thereof, and the pressure relief block 23 is installed with an arc plate 234 for blocking the pressure relief pipe 233.

[0053] The pressure relief pipe 233 is long enough, and the end of the pressure relief pipe 233 away from the giving way cylinder 24 is connected to the existing water tank. During specific operation, when the water pressure is too large, the vertical rod 231 is driven upward during the upward movement of the pressure relief block 23. At this time, the telescopic spring 232 is compressed, and the gap between the bottom of the pressure relief block 23 and the top of the pressure relief chamber 22 can give way and relieve the pressure of the water flow with a larger water pressure, so that the excess water flow inside the control body 1 enters the gap between the bottom of the pressure relief block 23 and the top of the pressure relief chamber 22. When the pressure relief block 23 passes over the pressure relief pipe 233, the pressure relief pipe 233 is connected with the gap between the bottom of the pressure relief block 23 and the top of the pressure relief chamber 22. At this time, the water between the bottom of the pressure relief block 23 and the top of the pressure relief chamber 22 flows out through the pressure relief pipe 233. The outflowing water can be discharged to the inside of the existing water tank for reuse, and the pressure relief pipe 233 can relieve the pressure of the water flow inside the pressure relief chamber 22.

[0054] Furthermore, the pressure relief pipe 233 can effectively reduce the water pressure inside the liquid inlet part 13, prevent the pressure relief block 23 from traveling beyond the length of the give way cylinder 24, and thus prevent the telescopic spring 232 from failing, thereby ensuring the smoothness and integrity of the pressure relief process. The arc plate 234 can seal the pressure relief pipe 233 to avoid the possibility of water backflow inside the pressure relief pipe 233.

[0055] Continue to refer to Figure 4 In order to ensure that the pressure relief pipe 233 can relieve the water flow with excessive pressure and different pressures, multiple pressure relief pipes 233 are evenly arranged along the length direction of the give way cylinder 24.

[0056] During specific operation, when water pressure acts on the pressure relief block 23, it will drive the block to move upward. At the same time, the telescopic spring 232 will be compressed. At this time, a gap will be formed between the bottom of the pressure relief block 23 and the top of the pressure relief chamber 22. This gap can effectively allow a large amount of water to flow into the gap between the bottom of the pressure relief block 23 and the top of the pressure relief chamber 22. When the pressure relief block 23 completely passes over the pressure relief pipe 233, the pressure relief pipe 233 and the bottom of the pressure relief block 23 and the top of the pressure relief chamber 22 form a continuous channel, thereby releasing pressure through the pressure relief pipe 233.

[0057] By adjusting the height of the pressure relief round block 23, the plurality of pressure relief pipes 233 can correspond to different water pressures respectively, thereby achieving precise pressure relief processing for water flows with different water pressures.

[0058] Reference Figure 5 The opening and closing disc 12 is symmetrically mounted with support shafts 121 extending along the length direction of the giving way cylinder 24 , and the support shafts 121 are rotatably mounted on the control body 1 , and the opening and closing disc 12 is jointly mounted on the two support shafts 121 .

[0059] The support shaft 121 near the side of the yield cylinder 24 passes through the control body 1, and a driving motor 122 for driving the opening and closing disc 12 to rotate is installed on the corresponding support shaft 121, and a switch 123 for controlling the start and stop of the driving motor 122 is installed on the driving motor 122.

[0060] During specific operation, when water flows from the inside of the pressure relief chamber 22 through the drain trough 111 into the storage part 14 and reaches a certain height, the drive motor 122 is started at this time. During the rotation of the output shaft of the drive motor 122, the corresponding support shaft 121 is driven to rotate. The support shaft 121 close to the drive motor 122 and the support shaft 121 far away from the drive motor 122 cooperate with each other to drive the opening and closing disc 12 to rotate 90 degrees. At this time, the interior of the control body 1 is opened, that is, the storage part 14 is connected with the existing pipeline. At this time, the water inside the storage part 14 flows into the existing pipeline.

[0061] When the water flows subsequently, as long as the water flow inside the storage part 14 reaches a certain height, the driving motor 122 automatically opens and cooperates with the support shaft 121 to drive the opening and closing disc 12 to open. When the water flow inside the storage part 14 is lower than this height, the driving motor 122 automatically reverses and drives the opening and closing disc 12 to reset through the support shaft 121. At this time, the inside of the control body 1 is closed again. After the water flow inside the storage part 14 returns to this height, the driving motor 122 automatically opens again.

[0062] Repeating the above actions in cooperation with the storage unit 14 can keep the water flowing into the existing pipeline at a constant pressure, thereby avoiding the possibility of damage to the inner wall of the existing pipeline caused by uneven pressure of the water flowing into the existing pipeline.

[0063] Reference Figure 5 and Figure 6 In order to ensure that the driving motor 122 can be adaptively opened, the floating block 126 and the linkage rod 125 designed in the present invention cooperate with each other to adaptively open the driving motor 122 according to the water flow height. Specifically, a clearance groove 124 is opened inside the control body 1, and a linkage rod 125 is slidably arranged inside the clearance groove 124. The floating block 126 is installed at one end of the linkage rod 125 located inside the control body 1, and the linkage connecting rod 127 that cooperates with the switch 123 is installed at the end of the linkage rod 125 away from the floating block 126.

[0064] A spring is provided on the support shaft 121 near the driving motor 122, which can automatically reset the corresponding support shaft 121. During operation, when water flows from the inside of the pressure relief chamber 22 through the drain chute 111 and into the storage part 14, the floating block 126 moves up synchronously with the increase of the water flow height. During the upward movement of the floating block 126, the linkage connecting rod 127 is driven to move up through the linkage rod 125. During the upward movement of the linkage connecting rod 127, the switch 123 can be opened. The support shaft 121 near the driving motor 122 rotates forward, the spring is tightened, and then the linkage connecting rod 127 is driven to adaptively open the switch 123 through the cooperation of the water depth and the floating block 126, thereby reducing the delay required to open the switch 123 by external force.

[0065] When the water flow height is lower than a certain height, the floating block 126 is no longer affected by the buoyancy of the water flow, and moves downward through the linkage rod 125 to drive the linkage link 127 downward. At this time, the switch 123 is closed, and the hinge spring resets the opening and closing disc 12 through the support shaft 121, thereby controlling the main body 1 to close again. After the water flow in the storage part 14 returns to this height, the floating block 126 cooperates with the linkage rod 125 and the linkage link 127 to drive the drive motor 122 to open automatically again, so that the water flow flowing into the existing pipeline can be adaptively kept in a constant pressure state at all times.

[0066] Reference Figure 6 An air valve 128 for exhausting the storage portion 14 is provided through the interior of the clearance groove 124 to facilitate the liquid to enter the storage portion 14 .

[0067] As the storage part 14 is filled with water, the gas inside the storage part 14 needs to be discharged in time. In order to ensure that the water flow inside the pressure relief chamber 22 smoothly enters the storage part 14, the air valve 128 provided by the present invention can discharge the air above the storage part 14 during the process of the storage part 14 being filled with water, thereby ensuring that the pressure difference between the inside and outside of the storage part 14 is consistent, so that the water flow smoothly enters the storage part 14.

[0068] When the floating block 126 is completely moved into the clearance groove 124, the floating block 126 can block the inside of the clearance groove 124. At this time, the gas inside the storage part 14 cannot be discharged from the air valve 128, thereby avoiding the possibility of water overflowing from the air valve 128.

[0069] Replay Figure 3 In order to avoid the possibility that the liquid inlet 13 may be damaged due to the impact of excessive water flow, the connecting pipe 131 designed in the present invention can relieve the pressure of water with excessive water pressure. Specifically, the liquid inlet 13 and the storage part 14 are connected through the connecting pipe 131 with a U-shaped structure, and a sealing rod 132 is installed at the bottom of the pressure relief block 23. The end of the sealing rod 132 away from the pressure relief block 23 is sealed and inserted into the connecting pipe 131.

[0070] The connecting pipe 131 is arranged outside the control body 1, one end of the connecting pipe 131 is connected with the liquid inlet part 13, and the other end of the connecting pipe 131 is connected with the storage part 14. During specific operation, when the water flow reaches the liquid inlet part 13 and reaches a certain pressure, the pressure relief block 23 moves up, and the pressure relief block 23 drives the sealing rod 132 to move up during the upward movement. When the pressure relief block 23 moves up to a certain height, the sealing rod 132 is separated from the connecting pipe 131, and the water flows into the storage part 14 through the connecting pipe 131, and then the connecting pipe 131 can further relieve the pressure on the water flow inside the liquid inlet part 13 to avoid the possibility of internal damage to the control body 1 caused by excessive water pressure at the liquid inlet part 13.

[0071] Reference Figure 7 A liquid leakage port 112 is provided at the bottom of the blocking disk 11 .

[0072] After a relatively large water flow contacts the blocking disc 11 , the leakage port 112 can perform pressure division on the water flow to avoid the possibility that the water flow cannot enter the pressure relief chamber 22 in time and be discharged from the pressure relief chamber 22 due to excessive water pressure.

[0073] The sliding joints of the above-mentioned parts are all waterproof and sealed to avoid the possibility of water overflowing from the sliding joints of the parts.

[0074] Embodiment 2: Reference Figure 8 On the basis of the first embodiment, the end of the connecting pipe 131 of the present invention away from the liquid inlet portion 13 can also be connected with the liquid outlet portion 15. In specific operation, when the water flow reaches the liquid inlet portion 13 and reaches a certain pressure, the pressure relief block 23 moves upward. During the upward movement of the pressure relief block 23, the sealing rod 132 is driven to move upward synchronously. When the pressure relief block 23 moves up to a certain height, the sealing rod 132 is separated from the connecting pipe 131, and the water flows through the connecting pipe 131 into the liquid outlet portion 15, thereby also playing a role in relieving the pressure of the water flow at the liquid inlet portion 13.

[0075] The implementation principle of the present invention is: (1): Connect the connecting circular tube 3 near the liquid inlet 13 to the existing water tank, and install a water pump between the corresponding connecting circular tube 3 and the water tank to provide a power source for the flow of water, so that the water inside the existing water tank flows into the existing pipeline through the water pump, and then connect the connecting circular tube 3 near the liquid outlet 15 to the existing pipeline.

[0076] (2): Turn on the water pump, and the water flows through the water pump and enters the liquid inlet part 13 through the connecting circular pipe 3 near the liquid inlet part 13. At this time, the water flows inside the liquid inlet part 13: If the water flow pressure is large, the water inlet pressure inside the liquid inlet part 13 is high, and the pressure relief round block 23 will open, that is, at this time, the pressure relief round block 23 moves up and moves to the inside of the give way cylinder 24. At this time, the water flows into the pressure relief chamber 22, and the height inside the pressure relief chamber 22 gradually increases. When the water flow height inside the pressure relief chamber 22 reaches the height of the drainage trough 111, the water inside the pressure relief chamber 22 enters the storage part 14 through the drainage trough 111. At this time, the water body height inside the storage part 14 gradually increases. When the water body height inside the storage part 14 reaches a certain height, the opening and closing disc 12 opens, and the water inside the storage part 14 flows through the liquid outlet 15 into the existing pipeline.

[0077] (3): When the water flow entering the liquid inlet 13 is small, the water flow gathers inside the liquid inlet 13. When it reaches a certain height, the water flow has a certain pressure. The water pressure squeezes the pressure relief round block 23 upward. The storage part 14 treats low-flow water: When the water flow inside the liquid inlet 13 is small, the storage part 14 stores the water flow to increase the water flow pressure and moves it to the inside of the give way cylinder 24. At this time, the water flow enters the pressure relief chamber 22. The height of the pressure relief chamber 22 gradually increases. When the water flow height inside the pressure relief chamber 22 reaches the height of the drainage trough 111, the water inside the pressure relief chamber 22 enters the storage part 14 through the drainage trough 111. At this time, the water body height inside the storage part 14 gradually increases. When the water body height inside the storage part 14 reaches a certain height, the opening and closing disc 12 opens, and the water flow inside the storage part 14 enters the existing pipeline through the liquid outlet 15.

[0078] (4): When the water pressure inside the liquid inlet part 13 is relatively high, the drain groove 111 cannot discharge the water inside the pressure relief chamber 22 to the storage part 14 in time. At this time, the pressure relief round block 23 moves upward while driving the vertical rod 231 upward, and the telescopic spring 232 is compressed synchronously. The gap between the bottom of the pressure relief round block 23 and the top of the pressure relief chamber 22 can make way for the water inside the pressure relief chamber 22 to release pressure, so that the excess water inside the control body 1 enters the gap between the bottom of the pressure relief round block 23 and the top of the pressure relief chamber 22, thereby playing a pressure relief role.
