Technical Field

[0001] The utility model relates to the technical field of secondary water supply, and more specifically to an antibacterial secondary water supply pressure stabilizing tank for ensuring water quality. Background Art

[0002] A pressure regulating tank (or diaphragm air pressure tank) is a water pressure regulating container commonly used in pressure stabilizing and boosting water supply equipment. It is used to reduce damage to water supply equipment such as pipes and water pumps caused by pressure fluctuations, and plays a role in ensuring water supply safety.

[0003] At present, the diaphragm pressure tanks commonly used in secondary water supply equipment are all tank structures, with the interior divided into a water chamber and an air chamber, and the water chamber is connected to the water outlet pipe through a relatively thin pipe. Since the secondary water supply equipment needs to operate continuously without interruption, the pressure tank often maintains a constant pressure state, which results in the water in the water chamber being almost never replaced, creating conditions for the growth of bacteria, and even forming "stinky water" and "black water", which seriously affects the water quality safety of the secondary water supply.

[0027] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0028] [Example]

[0029] Combination Figure 1 and Figure 2As shown, a secondary water supply pressure-stabilizing tank of the present embodiment with an antibacterial type for ensuring water quality comprises a pipe 1, an air chamber shell 2 and an air bag 5. One end of the pipe 1 has a water inlet and the other end has a water outlet. The lumen of the pipe 1 forms a water chamber 1A of the pressure-stabilizing tank. The air chamber shell 2 is arranged on the side wall of the pipe 1. The inner cavity of the air chamber shell 2 forms an air chamber 2A of the pressure-stabilizing tank. The air chamber 2A is connected with the water chamber 1A. The air bag 5 is arranged in the air chamber 2A, and the air bag 5 is filled and tightly attached to the inner wall of the air chamber shell 2. In this way, a pipeline-type pressure-stabilizing tank is formed. The secondary water supply pressure-stabilizing tank uses the pipe 1 as the water chamber of the pressure-stabilizing tank, and the air chamber shell 2 arranged on the side wall of the pipe 1 as the air chamber of the pressure-stabilizing tank. The air bag 5 fills the air chamber 2A, and the water stored in the water chamber 1A will be replaced in real time as the user uses water, which fundamentally eliminates the water storage problem of the water chamber of the existing pressure-stabilizing tank, eliminates the "stinky water" and "black water" problems caused by bacterial growth, and ensures the water quality of tap water. Furthermore, when water pressure fluctuation occurs in the secondary water supply, the air bag 5 in the air chamber 2A provides a reaction force to supplement the water pressure, eliminate the pressure fluctuation, and achieve a pressure stabilizing effect.

[0030] like Figure 1 and Figure 2 As shown, in this embodiment, the airbag 5 is also connected to a pressure gauge 3, which is located outside the air chamber shell 2. The pressure gauge 3 can reflect the pressure inside the airbag 5, and the water pressure in the pipeline 1 interacts with the airbag 5 to reach a balanced state, so the pressure gauge 3 can reflect the water pressure in the pressure-stabilizing tank, which is convenient for intuitive display and adjustment of pressure. In addition, the airbag 5 is also connected to an inflation nozzle 4, which extends through the air chamber shell 2 to the outside of the air chamber shell 2, and the inflation nozzle 4 can be used to inflate and deflate the airbag 5, which is convenient for adjusting the airbag pressure.

[0031] In this embodiment, the airbag 5 matches the shape of the air chamber 2A after being filled, and part of the airbag 5 is sealed near the through-hole between the water chamber 1A and the air chamber 2A, so that the water in the pipeline 1 will not enter the side gap between the airbag 5 and the air chamber 2A to cause bacteria to grow. The water in the surge tank is basically located in the pipeline to avoid the formation of a stagnant dead water area, further preventing bacteria from growing in the surge tank. The above-mentioned pipeline 1 and air chamber shell 2 are made of stainless steel, and the airbag 5 and sealing components are made of food-grade sanitary materials, which are safe and hygienic.

[0032] Further preferably, the secondary water supply pressure stabilizing tank is installed on the outlet pipe of the secondary water supply equipment, which can eliminate the secondary water supply outlet pressure fluctuation and is easy to install. The water inlet diameter of the pipeline 1 is equal to the water outlet diameter, and flanges 1-1 are provided at the water inlet and outlet of the pipeline 1. During installation, the pressure stabilizing tank can be directly installed on the outlet pipe of the secondary water supply equipment using the flanges 1-1, which further facilitates the installation of the pressure stabilizing tank.

[0033] The present embodiment is an antibacterial secondary water supply pressure-stabilizing tank for ensuring water quality, which utilizes a pipe 1 (secondary water supply connecting pipe) as a water chamber 1A of the pressure-stabilizing tank. During manufacture, an opening can be made on the side wall of the pipe 1, and an air bag 5 is arranged in the air chamber shell 2, and then the air chamber shell 2 is welded and fixed to the opening on the side wall of the pipe 1.

[0034] When in use, the flanges 1-1 at both ends of the pipe 1 are connected to the outlet pipe of the secondary water supply by bolts, and air is filled through the inflation nozzle 4. The pressure value of the airbag 5 is observed through the pressure gauge 3, and the pressure gauge 3 shows that the set pressure has been reached. When the water outlet pipe discharges water, the water fills the outlet pipe and reaches the set water outlet pressure. Observe whether the data of the pressure gauge 3 on the pressure regulating tank is consistent with the set water outlet pressure. The airbag 5 is compressed under a constant pressure by the water pressure in the water chamber 1A. When the outlet water pressure fluctuates, due to the reaction force, the airbag 5 in the air chamber 2A eliminates the pressure fluctuation by responding to the deformation, and the airbag 5 supplements the water outlet pressure of the outlet pipe, which plays a role in stabilizing the pressure and alleviating the pressure fluctuation. The water chamber 1A is connected to the water outlet pipeline, and there is no independent water chamber. Since the water chamber 1A is a smooth tubular structure, the entire water outlet pipeline is used as a water chamber, and the water flows in and out at the same time, so that the water in the water chamber 1A can pass through completely, eliminating the water inside the water chamber 1A, so it can inhibit the reproduction of bacteria in the pressure stabilizing tank, and eliminate the "stinky water" and "black water" problems caused by bacteria growth, so as to ensure the safety of the secondary water supply quality, and is particularly suitable for the pressure stabilization of secondary booster pipelines such as differentiated water supply.

[0035] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in the field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
