[0002] The flow stabilizer is an important component in negative pressure-free water supply equipment. It mainly regulates and stabilizes the pressure and flow rate in the water supply system, thereby ensuring that no negative pressure is generated when water is drawn from the tap water network, thus preventing negative pressure, stabilizing the flow rate, and protecting the system.

[0003] Reference document: A pressure-stabilizing tank for tap water without negative pressure, publication number: CN219586833U, which can effectively detect the pressure of the stabilizing tank and display the specific value by setting a pressure display device, so as to facilitate centralized control of the entire water supply system and ensure that the pressure-stabilizing tank for tap water without negative pressure can stably supply tap water to users.

[0004] Existing pressure-free flow stabilizing tanks for tap water typically use pressure sensors and vacuum suppressors for automated processing, balancing the internal air pressure by checking the tank. This approach is costly, and the internal components are prone to damage in humid environments due to the use of electronic tools. Furthermore, it is impossible to adjust the internal air pressure of the tank in a timely manner afterward. Therefore, we propose an innovative design based on the existing pressure-free flow stabilizing tanks for tap water. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are: this tap water pressure-free flow stabilizing tank...

[0014] 1. Through the internal structure of the air inlet connector, the lifting plate and sealing plug are pushed upward by buoyancy. The sealing plug engages with the second adjustment hole to seal the air inlet and prevent gas flow. Subsequently, when the water level inside the negative pressure stabilizing tank drops to a certain height, the lifting plate and sealing plug automatically slide down, opening the air inlet and vent to connect with the internal space of the negative pressure stabilizing tank, allowing air to enter and balancing the air pressure inside the negative pressure stabilizing tank.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 7This utility model provides a technical solution: a pressure-stabilizing tank for tap water, including a pressure-stabilizing tank body 1 and a support frame 2. The support frame 2 is welded and fixedly installed on the bottom surface of the pressure-stabilizing tank body 1, and a water inlet pipe 3 is welded and fixedly installed on the top left end of the pressure-stabilizing tank body 1. A drain pipe 4 is welded and fixedly installed on the bottom of the pressure-stabilizing tank body 1. An air inlet connector 5 is embedded and fixedly installed on the top right end of the pressure-stabilizing tank body 1. The air inlet connector 5 has a first adjustment hole 6 and a second adjustment hole 7 in its internal center. The first adjustment hole 6 is located below the second adjustment hole 7. An air inlet hole 8 is opened on the top frame of the air inlet connector 5. A limit cover 9 is sleeved on the outer side of the bottom end of the first adjustment hole 6. A through hole 10 is provided in the center of the limit cover 9.

[0026] The first adjustment hole 6 is equipped with a lifting plate 11, and the surface of the lifting plate 11 is provided with a vent hole 12. A sealing plug 13 is provided at the center of the top surface of the lifting plate 11, and the sealing plug 13 is located inside the second adjustment hole 7, which facilitates the subsequent installation of the adjustment components inside the air inlet connector 5 for assembly.

[0027] The second regulating hole 7 is interconnected with the internal space of the first regulating hole 6 and the air inlet hole 8. The diameter of the second regulating hole 7 is smaller than the diameter of the first regulating hole 6. The air inlets 8 are evenly distributed on the air inlet connector 5. The air inlets 8 are inclined upward from the outside to the inside, which facilitates the connection between the second regulating hole 7, the first regulating hole 6 and the air inlet hole 8, so that external gas can enter the interior of the negative pressure stabilizing tank 1 to balance the air pressure. The structure of the air inlet hole 8 prevents external impurities from entering the interior of the second regulating hole 7.

[0028] The lifting plate 11 is connected to the first adjustment hole 6 by a sliding connection, and the lifting plate 11 and the sealing plug 13 are integrated into one structure. The sealing plug 13 is connected to the second adjustment hole 7 by a sealing engagement. Ventilation holes 12 are distributed at equal angles on the lifting plate 11. The lifting plate 11 and the sealing plug 13 can slide synchronously. The sealing is achieved by the docking of the sealing plug 13 and the second adjustment hole 7. At the same time, the sealing plug 13 can be separated from the second adjustment hole 7 to allow air intake.

[0029] The top of the sealing plug 13 is chamfered, and the height of the sealing plug 13 is less than the height of the first adjustment hole 6 minus the height of the lifting plate 11. The diameter of the lifting plate 11 is less than the diameter of the through hole 10. The chamfer of the sealing plug 13 facilitates its sliding into the second adjustment hole 7. At the same time, the sealing plug 13 can slide completely into the first adjustment hole 6 when it slides down, so as to avoid affecting the air intake operation.

[0030] A connecting rod 14 is installed at the center of the bottom surface of the lifting plate 11, and the connecting rod 14 passes through the through hole 10. A connector 15 is sleeved on the outer side of the bottom end of the connecting rod 14, and a floating ball 16 is provided at the bottom end of the connector 15. A weight-increasing ball 17 is installed inside the floating ball 16. The floating ball 16 is located inside the negative pressure stabilizing tank 1. The connecting rod 14 is connected to the lifting plate 11 by embedding and fixing, and the diameter of the connecting rod 14 is smaller than the diameter of the through hole 10. The connection between the connecting rod 14 and the connector 15 is... The connection method is threaded fixation, and the connector 15 and the floating ball 16 are integrated structures. The floating ball 16 is hollow. According to the connector 15 and the floating ball 16 installed at the bottom of the connecting rod 14, the floating ball 16 can be pushed by the water level inside the negative pressure stabilizing tank 1 to maintain the stability of the rising and sealing of the lifting plate 11 and the sealing plug 13. When the water level inside the negative pressure stabilizing tank 1 drops, the floating ball 16 and the weight-adding ball 17 can be pulled down to automatically start air intake.

[0031] Working principle: According to Figures 1 to 7 First, the pressure-free flow stabilizing tank 1 can be placed stably using the support frame 2. Then, the pressure-free flow stabilizing tank 1 is connected to external pipes and a water pump via the inlet pipe 3 and the outlet pipe 4. Water is replenished to the pressure-free flow stabilizing tank 1 through the inlet pipe 3, maintaining a suitable water level inside. Simultaneously, based on the water level inside the pressure-free flow stabilizing tank 1 and the structure of the floating sphere 16, the floating sphere 16 is underwater, maintaining buoyancy. The floating sphere 16 is connected to the connecting rod 14... The lifting plate 11 and the sealing plug 13 are pushed to keep the sealing plug 13 and the second adjustment hole 7 locked and sealed to prevent air from entering. When the water level inside the subsequent negative pressure stabilizing tank 1 drops to the bottom, the floating ball 16 can fall through the weight-adding ball 17. The floating ball 16 pulls the lifting plate 11 down through the connecting head 15 and the connecting rod 14, so that the lifting plate 11 drives the sealing plug 13 to slide and separate from the second adjustment hole 7, so that the sealing plug 13 slides completely into the interior of the first adjustment hole 6. The limiting cover 9 limits the descent of the sealing plug 13 to prevent it from coming off, and releases the seal on the air inlet 8, allowing the air inlet 8 to communicate with the internal space of the negative pressure stabilizing tank 1 through the second adjusting hole 7, the vent hole 12 on the lifting plate 11, and the through hole 10. External gas enters the interior of the negative pressure stabilizing tank 1, balancing the air pressure inside the tank 1 and preventing negative pressure from forming inside the tank 1 due to the operation of the water pump or the inability to replenish water resources in time. The overall structure is simple, easy to maintain, and not easily damaged. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
