Description

Technical Field

[0001] This utility model relates to the field of pressure stabilization technology in water supply systems, specifically a pressure water tank that can improve the quality of water supply. Background Technology

[0002] In water supply systems, due to unstable raw water pressure, water hammer, or the need to store a certain amount of water, a pressure tank needs to be added to the pipeline system. The total amount of water in the pressure tank can be automatically adjusted according to the pressure of the pipeline system, thereby reducing water pressure and water hammer disturbances and ensuring the stability of the water supply pressure.

[0003] Currently, most pressure tanks use a plastic outer shell, with a rubber diaphragm dividing the interior into two chambers. One chamber is used to store water, serving as the water storage chamber. An inlet and outlet are located at the top of the water storage chamber, meaning the water inlet and outlet share the same space. The other chamber contains a certain amount of compressed air, serving as the air chamber. An air nozzle is located at the bottom of the air chamber. When the pressure in the pipeline system increases, water fills the water storage chamber, pushing the rubber diaphragm towards the air chamber to store more water. When the pressure in the pipeline system decreases, the rubber diaphragm moves in the opposite direction, pushing the water in the storage chamber back into the pipeline system to stabilize the pressure.

[0004] In use, it was found that when the pressure of the pipeline system fluctuates little, the water flow does not disturb the water stored in the storage chamber. When most of the water in the storage chamber is undisturbed, it is like a stagnant pool, which easily leads to the deposition of impurities in the water into the pressure tank. At the same time, microorganisms multiply in large quantities, resulting in a decline in water quality and affecting people's health when using water. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a pressure water tank that can improve the quality of water supply.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A pressure water tank that can improve water supply quality includes an upper tank, a lower tank connected to the lower end of the upper tank, and an elastic inner diaphragm installed at the connection between the upper and lower tanks. The elastic inner diaphragm divides the inner cavity of the pressure water tank into a water storage chamber and an air chamber. The original state of the elastic inner diaphragm is a cylindrical shape extending downward to the bottom of the lower tank. The lower tank is provided with an air inlet. The upper tank is provided with a water tank inlet at the end away from the lower tank. The elastic inner diaphragm is provided with a water storage chamber outlet at the end away from the upper tank. The lower tank is provided with a water tank outlet. The tank also includes a water outlet pipe connecting the water storage chamber outlet and the water tank outlet.

[0007] Furthermore, a first water pipe connector is provided at the outlet of the water storage chamber, and a second water pipe connector is provided at the outlet of the water tank. One end of the water pipe is connected to the outlet of the water storage chamber through the first water pipe connector, and the other end is connected to the outlet of the water tank through the second water pipe connector.

[0008] Furthermore, the water outlet of the water storage chamber is located at the bottom of the elastic inner diaphragm near the side wall of the lower tank. Furthermore, the water tank outlet is located on the side wall of the lower tank near the bottom.

[0009] Furthermore, the outlet pipe is a flexible pipe.

[0010] Furthermore, the length of the outlet pipe is such that it can coil around the vertical centerline of the pressure tank at least once below the elastic inner diaphragm.

[0011] As an optional implementation, the upper end of the lower box body is provided with a first connecting part around the outer periphery of the lower box body, and the lower end of the upper box body is provided with a second connecting part around the outer periphery of the upper box body. The lower box body and the upper box body are connected through the first connecting part and the second connecting part. The upper part of the elastic inner diaphragm is provided with an outwardly protruding part extending radially outward, and the elastic inner diaphragm is disposed between the first connecting part and the second connecting part through the outwardly protruding part.

[0012] Furthermore, the first connecting portion includes a first protrusion extending radially from the lower housing body and a second protrusion extending from the outer edge of the first protrusion toward the upper housing side, wherein the protrusion is disposed on the first protrusion and abuts against the second protrusion.

[0013] Furthermore, a slot is provided on the side of the first protrusion near the second protrusion, and a first retaining ring is provided on the outer edge of the outer protrusion extending toward the side of the first protrusion, the first retaining ring being fitted with the slot; an annular step is provided on the upper part of the outer protrusion at the position corresponding to the retaining ring, and a second retaining ring is provided on the inner diaphragm fixing ring extending out of the fourth protrusion toward the lower housing side, the second retaining ring being located between the annular step and the second protrusion.

[0014] Furthermore, the upper and lower housings are fixedly connected by heat-fusion of the second and fourth protrusions.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: According to this invention, by setting a water outlet for the storage chamber at the bottom of the elastic inner diaphragm and connecting it to a water pipe connector located on the lower tank via a water outlet pipe, the water outlet of the storage chamber is positioned relatively far from the water inlet of the water tank. This ensures that the water stored in the pressure tank is always in a flowing state, similar to a pipeline system, avoiding the drawbacks of stagnant water such as debris accumulation and excessive microbial growth. This improves the water supply quality of the water supply system. Attached Figure Description

[0020] 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.

[0021] As shown in the figure, a pressure water tank that can improve the quality of water supply includes an upper tank 1, a lower tank 4 connected to the lower end of the upper tank 1, and an elastic inner diaphragm 3 installed at the connection between the upper tank 1 and the lower tank 4.

[0022] The elastic inner diaphragm 3 divides the inner cavity of the pressure tank into a water storage chamber located above and an air chamber located below. The original state of the elastic inner diaphragm 3 is a cylindrical shape extending downward to the bottom of the lower tank body 4. An air inlet 6 is provided on the lower tank body 4. A one-way valve is installed at the air inlet 6. The one-way valve is used to connect an air inflation device for inflation when needed and automatically closes after inflation is completed.

[0023] A water tank inlet 12 is provided at the end of the upper tank 1 away from the lower tank 4, and a water storage chamber outlet 33 is provided at the end of the elastic inner diaphragm 3 away from the upper tank 1. A water tank outlet 42 is provided on the lower tank 4, and a water outlet pipe 5 is connected between the water storage chamber outlet 33 and the water tank outlet.

[0024] A first water pipe connector 7 is provided at the water outlet 33 of the water storage chamber, and a second water pipe connector 8 is provided at the water outlet of the water tank. One end of the water outlet pipe 5 is connected to the water outlet 33 of the water storage chamber through the first water pipe connector 7, and the other end is connected to the water outlet 42 of the water tank through the second water pipe connector 8.

[0025] Specifically, a blind hole structure can be made at the bottom of the elastic inner diaphragm 3 by extending it away from the water storage chamber, and then a water storage chamber outlet 33 can be opened on the side wall of the blind hole, with the first water pipe connector installed at the water storage chamber outlet 33.

[0026] In this embodiment, the blind hole structure is located at the bottom of the elastic inner diaphragm 3 near the side wall of the lower tank 4; since the water outlet 33 of the water storage chamber is located on the side wall of the blind hole, that is, the water outlet 33 of the water storage chamber is located at the bottom of the elastic inner diaphragm 3 near the side wall of the lower tank 4. The water outlet 33 of the water storage chamber can be configured in different ways and is not limited to the scheme used in this embodiment.

[0027] The water tank outlet 42 is located on the side wall of the lower tank 4 near the bottom. The water outlet pipe 5 is a flexible pipe, and can be made of materials such as plastic that meet the requirements.

[0028] The length of the outlet pipe 5 is sufficient to allow it to coil around the vertical center line of the pressure tank at least once below the elastic inner diaphragm 3. This ensures that the elastic inner diaphragm 3 can move normally when needed and will not be affected by the second water pipe joint 8.

[0029] In this embodiment, the upper end of the lower housing 4 is provided with a first connecting part 41 surrounding the outer periphery of the main body of the lower housing 4, and the lower end of the upper housing 1 is provided with a second connecting part 11 surrounding the outer periphery of the main body of the upper housing 1. The lower housing 4 and the upper housing 1 are connected through the first connecting part 41 and the second connecting part 11. The upper part of the elastic inner diaphragm 3 is provided with an outwardly extending part 31 extending radially outward. The elastic inner diaphragm 3 is disposed between the first connecting part 41 and the second connecting part 11 through the outwardly extending part 31. In this embodiment, mounting holes can be provided on the first connecting part 41 and the second connecting part 11, and then bolts or other connecting parts can be used to pass through the mounting holes and then nuts can be fitted to achieve the connection between the upper housing 1 and the lower housing 4.

[0030] In another embodiment, in the above-described connection method between the upper housing 1 and the lower housing 4, the connection method can be further optimized by the following technical features: the first connecting part 41 includes a first protrusion 411 extending radially from the main body of the lower housing 4 and a second protrusion 412 extending from the outer edge of the first protrusion 411 toward the side of the upper housing 1. The outer protrusion 31 is disposed on the first protrusion 411 and abuts against the second protrusion 412. Such a connection structure further increases the connection strength between the elastic inner diaphragm 3 and the upper housing 1 and the lower housing 4.

[0031] In this embodiment, the upper housing 1 and the lower housing 4 are not connected by bolts. Instead, the following technical features are further provided in the above technical solution: a groove is provided on the side of the first protrusion 411 near the second protrusion 412; a first retaining ring 32 extends from the outer edge of the outer protrusion 31 toward the side of the first protrusion 411 and is fitted with the groove; an annular step is provided on the upper part of the outer protrusion 31 at the position corresponding to the retaining ring; a second retaining ring 21 extends from the fourth protrusion 112 toward the side of the lower housing 4 and is provided between the annular step and the second protrusion 412.

[0032] In this embodiment, the upper tank 1 and the lower tank 4 are connected by heat fusion of the second protrusion 412 and the fourth protrusion 112 to form a complete pressure water tank. At the same time, the elastic inner diaphragm 3 is pressed and connected between the upper tank 1 and the lower tank 4 by the inner diaphragm fixing ring 2.

[0033] In this embodiment, a base is also provided at the bottom of the lower housing 4 by heat fusion connection.

[0034] In use, the water supply pipe in the pipeline system is disconnected, one end is connected to the water inlet 12 of the water tank, and the other end is connected to the second water pipe connector 8 located on the lower tank body 4. An air pump or air compressor, used as an inflation device, is connected to a one-way valve (commonly known as an air nozzle) to inflate the air chamber of the pressure water tank, bringing the air pressure in the air chamber to approximately 0.05 MPa. During the service life of the pressure water tank, the air pressure in the air chamber is tested periodically to maintain it at around 0.05 MPa.

[0035] By adopting the technical solution of this application, the outlet of the water storage chamber is set at a position relatively far from the inlet of the water tank, so that the water stored in the pressure water tank is always in a flowing state, just like in the pipeline system. This avoids the various drawbacks of stagnant water, such as the accumulation of debris and excessive reproduction of microorganisms, and improves the water supply quality of the water supply system.
