Description

Technical Field

[0001] This utility model belongs to the technical field of pressure water storage tanks, and more specifically, relates to a safe and long-lasting pressure water storage tank. Background Technology

[0002] Pressure storage tanks are mainly used in water purification systems to store purified water while maintaining a stable outlet water pressure.

[0003] Existing pressure water tanks consist of two outer tanks, sealed together. Inside, a rubber inner liner separates the water from the air. When the water purifier produces water, it forces water into the inner liner, causing it to expand and compressing the air. As the water level increases, the internal pressure rises. When a certain pressure is reached, the purifier stops producing water, controlled by a pressure switch. When the user turns on the tap, the inner liner contracts under air pressure, expelling the water. Once the pressure drops to a certain level, the purifier resumes production, and the cycle repeats. Generally, in existing pressure water tanks, the water pressure inside the rubber inner liner and the air pressure outside are balanced. The more water is poured into the inner liner, the more the air outside is compressed.

[0004] Due to the material properties of the rubber liner, it cannot completely prevent air from passing through, and in fact, the stretched rubber liner can amplify the airflow. Therefore, existing pressure water tanks will experience internal air leakage after prolonged use, leading to a reduced lifespan. Utility Model Content

[0005] This invention provides a safe and long-lasting pressure water storage tank, which can slow down the rate of air leakage in the air chamber and improve safety.

[0006] This utility model provides a safe and long-lasting pressure water storage tank, including...

[0007] The barrel body has a sealed cavity inside;

[0008] The rubber inner liner, made of elastic material, is located within the cavity and fixedly connected to the inner wall of the cavity, dividing the cavity into upper and lower chambers: a water chamber and an air chamber. The air chamber is a sealed chamber.

[0009] A support plate is disposed within the air cavity; the edge of the support plate is connected to the inner wall of the air cavity (the connection referred to herein includes movable connection and fixed connection); at least one vent hole is provided in the middle of the support plate, the vent hole being a ventilation channel on the upper and lower sides of the support plate; the support plate is located within the extension range of the rubber inner liner to abut against the rubber inner liner and restrict its extension.

[0010] As a further improvement of this utility model, when the rubber inner liner is filled with water and has not deformed to the point of abutting the support plate, the pressure of the water cavity and the air cavity are balanced; when the rubber inner liner is filled with water and deformed to the point of abutting the support plate, the pressure of the air cavity is constant, and the pressure inside the water cavity is proportional to the water injection pressure.

[0011] As a further improvement of this utility model, the barrel body includes an upper barrel body and a lower barrel body; the upper barrel body and the lower barrel body are sealed and fixedly connected.

[0012] As a further improvement of this utility model, the part connecting the upper barrel and the lower barrel is the upper barrel connecting end; the upper barrel connecting end is the edge of the upper barrel opening end, and the upper barrel connecting end protrudes outward; the inner periphery of the upper barrel connecting end is provided with an upper groove opening.

[0013] The part connecting the lower bucket body and the upper bucket body is the lower bucket body connection end, which is the edge of the lower bucket body opening end and protrudes outward; the lower bucket body has a groove opening on its inner periphery.

[0014] The upper groove opening matches the lower groove opening to form an installation groove for installing the edge of the rubber inner liner.

[0015] As a further improvement of this utility model, the middle part of the air chamber protrudes into the inner cavity to form an abutment edge, and the abutment edge is arranged circumferentially along the inner wall of the air chamber; the outer periphery of the support plate is provided with an abutment protrusion; the abutment protrusion abuts against the abutment edge, the abutment protrusion and the abutment edge match each other, and the abutment protrusion and the abutment edge are fixedly connected or abut against each other.

[0016] As a further improvement of this utility model, a fixing plate is provided on the outer periphery of the support plate, and the fixing plate is welded to the barrel wall of the air chamber.

[0017] As a further improvement of this utility model, the barrel body is made of at least metal or polypropylene material.

[0018] As a further improvement of this utility model, the support plate is movably placed inside the air cavity; the edge of the support plate is slidably connected to the inner wall of the cavity; when the support plate is at the end of the sliding range, it is used to support the expanded rubber liner, and in this state the support plate and the bottom wall of the air cavity still maintain a distance.

[0019] As a further improvement of this utility model, a support ring is fixedly provided at the lower end of the support plate; when the support ring abuts against the bottom wall of the air cavity, the support plate is located at the end of the sliding range to support the support plate to support the expansion of the rubber inner liner.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. By installing a support plate in the air chamber, the rubber inner liner can be supported when water is injected and stretched, preventing it from deforming further downwards. This results in the air pressure in the air chamber remaining constant because the rubber inner liner cannot continue to stretch and deform, while the water pressure inside the rubber inner liner will still increase due to the increased water injection pressure, causing the water pressure to exceed the air pressure and disrupting the water-air pressure balance. In this way, compared to existing pressure storage tanks with balanced water and air pressure, the air pressure under water injection conditions is reduced. Even if a pressure storage tank explodes due to its inability to withstand internal pressure, the explosion effect of the pressure storage tank in this solution will be significantly smaller than that of existing pressure storage tanks with balanced water and air pressure because the internal air pressure is lower than the water pressure.

[0022] 2. Since the support plate can support and prevent further stretching and deformation of the rubber liner, it can also reduce the speed at which air passes through the rubber liner in the air chamber. This is because after the rubber liner is stretched, the gaps between its molecules will increase. The existing pressure water tank's rubber liner will be stretched to its limit. Under water injection conditions, the air in the air chamber will accelerate through the rubber liner, especially since the air in the air chamber itself is kept under compressed high pressure.

[0037] Specific Implementation Example 1: Please refer to Figures 1-4 A safe and long-lasting pressure water storage tank includes a tank body, a rubber inner liner 3, and a support plate 4.

[0038] The barrel body includes an upper barrel body 1 and a lower barrel body 2. The upper barrel body 1 and the lower barrel body 2 are arranged opposite each other and tightly sealed together, forming a cavity in which the rubber inner liner 3 and the support plate 4 are both arranged.

[0039] Specifically, such as Figure 1 As shown, the upper tank 1 has a water inlet 12 at its upper end for connecting to an external water injection device. The lower tank 2 has an air inlet 24 at its lower end for connecting to an external air injection device.

[0040] In this embodiment, the part connecting the upper barrel 1 and the lower barrel 2 is the upper barrel connecting end 11; the upper barrel connecting end 11 is the edge of the open end of the upper barrel 1, and the outer periphery of the upper barrel connecting end 11 protrudes outward; an upper groove opening 111 is formed on the inner periphery of the upper barrel connecting end 11. The part connecting the lower barrel 2 and the upper barrel 1 is the lower barrel connecting end 21; the lower barrel connecting end 21 is the edge of the open end of the lower barrel 2, and the outer periphery of the lower barrel connecting end 21 protrudes outward; a lower groove opening 211 is formed on the inner periphery of the lower barrel 2. The upper groove opening 111 and the lower groove opening 211 match to form an installation groove for installing the edge of the rubber inner liner 3. The rubber inner liner 3 is sealed and fixedly connected to the inner wall of the cavity. The specific installation method of the rubber inner liner 3 is a conventional technical means and will not be described in detail here.

[0041] The rubber inner liner 3 is made of elastic material and divides the cavity into two chambers: a water chamber 13 and an air chamber 23. The air chamber 23 is a closed chamber with a fixed amount of air.

[0042] A support plate 4 is disposed within the air cavity 23. A vent 42 is provided in the middle of the support plate 4, serving as a ventilation channel between the upper and lower sides of the support plate 4. The support plate 4 is located within the extension range of the rubber inner liner 3 to abut against the rubber inner liner 3 and restrict its extension. The connection method between the support plate 4 and the inner wall of the air cavity 23 can vary depending on the barrel material, as long as the fixed connection of the support plate 4 is satisfied. In this embodiment, the barrel 1 is made of polypropylene, therefore the middle of the air cavity 23 protrudes inward to form a stepped abutment edge 22, which is circumferentially arranged along the inner wall of the air cavity 23. An abutment protrusion 41 is provided along the outer periphery of the support plate 4; the abutment protrusion 41 abuts against the abutment edge 22, and the abutment protrusion 41 and the abutment edge 22 are matched, and the abutment protrusion 41 and the abutment edge 22 are fixedly connected or abut against each other.

[0043] Since the rubber inner liner 3 is sealed to the inner wall of the cavity, when water begins to be injected into the water cavity 13, the rubber inner liner 3 will deform and stretch under pressure, compressing the air cavity 23. The volume of the air cavity 23 will be compressed, and the pressure will increase. When the rubber inner liner 3 is filled with water and has not deformed to the point of contacting the support plate 4, the pressures of the water cavity 13 and the air cavity 23 are balanced. When the rubber inner liner 3 is filled with water and deformed to the point of contacting the support plate 4, the pressure of the air cavity 23 is constant. The pressure inside the water cavity 13 is proportional to the water injection pressure, that is, the water pressure inside the water cavity 13 will still increase due to the water injection pressure, but the rubber inner liner 3 can no longer deform and stretch, and the air pressure inside the air cavity 23 can no longer increase.

[0044] Working Principle: During use, water is injected into the water chamber 13 by an external water injection device. The rubber inner liner 3 is compressed and deformed, thus compressing the volume of the air chamber 23. Consequently, the air pressure within the air chamber 23 increases, and the air pressure and water pressure in the water chamber 13 are balanced. This continues until the rubber inner liner 3 extends to contact the support plate 4. Due to the influence of the support plate 4, the rubber inner liner 3 can no longer extend and deform. Therefore, the water pressure in the water chamber 13 will only increase due to the influence of the external water injection device, but the rubber inner liner 3 itself will no longer deform. Thus, the air chamber 23 will no longer be compressed, and the air pressure remains constant, resulting in a water pressure greater than the air pressure. Therefore, compared to existing pressure water tanks where water pressure equals air pressure, the internal pressure is significantly lower. Even if the pressure water tank in this embodiment were to explode, the explosive force would be significantly less than that of existing pressure water tanks, achieving a safer usage. In addition, since the deformation of the rubber inner liner 3 is limited, the speed at which air in the air cavity permeates through the rubber inner liner is also not large when the water is stored. This is because the intermolecular distance of the rubber inner liner 3 is smaller due to the weak elastic deformation, and the upper limit of the air pressure in the air cavity is also lower, which will also lead to a slower speed and time of air permeation and leakage, thus achieving the goal of a longer service life.

[0045] Specific Implementation Example 2: Please refer to Figures 6-7Unlike the first embodiment, the barrel body is made of metal. The upper barrel body 1 and the lower barrel body 2 are welded together. A support plate 4 is provided at the lower end of the rubber inner liner 3. The support plate 4 is located in the air cavity 23. A fixing piece 43 is provided on the edge of the support plate 4. The fixing piece 43 is fixedly connected to the barrel wall of the air cavity 23. In this embodiment, the fixing piece 43 is welded together.

[0046] Preferably, the upper barrel 1 includes an upper lid and a barrel body, and the lower barrel 2 is the lower lid. The upper lid is welded to the upper opening of the cylindrical barrel body, and the lower lid is welded to the lower opening of the cylindrical barrel body, thus forming an internal cavity of the barrel body. A plastic inner liner is provided in the upper part of the inner cavity of the barrel body, and an inlet 12 for connecting to an external water pipe is provided at the upper end of the plastic inner liner. The inlet 12 passes through the upper lid and is exposed to the outside. A rubber inner liner 3 is provided inside the plastic inner liner, and a metal support ring is provided on the lower inner side of the rubber inner liner 3. The metal support ring presses and fixes the rubber inner liner 3 and the plastic inner liner inside the barrel body. The specific fixing method adopts conventional technical means, including but not limited to: applying pressure to the outside of the barrel body so that the rubber inner liner 3 and the plastic inner liner are fixed by the pressure of the barrel body and the metal support ring.

[0047] Specific Implementation Example 3: Please refer to Figures 8-9 Unlike embodiment two, the support plate 4 is placed inside the air cavity 23 below the rubber inner liner 3. The edge of the support plate 4 is slidably connected to the cavity wall of the air cavity 23, rather than being fixedly or detachably connected. A support ring 44 is fixedly provided at the lower end of the support plate 4. When the barrel is placed vertically, the support ring 44 abuts against the bottom surface of the barrel to limit the position of the support plate 4. Since the support plate 4 can support the continuously expanding rubber inner liner 3 to avoid excessive air pressure in the air cavity 23, the different heights of the support ring 44 can determine the maximum air pressure threshold of the air cavity 23.

[0048] The support plate 4 is movably connected to the tank body, and the support ring 44 is also relatively movable to the tank body. Therefore, the installation of the support plate 4 is convenient, reducing welding processes, requiring less stringent conditions on the tank body itself, and lowering costs. Simultaneously, when water is injected into the water chamber 13, the rubber inner liner 3 expands axially. Even if the support ring 44 is not against the bottom wall of the tank body (for example, if the tank body is placed horizontally), the rubber inner liner 3 will still move axially against the support plate 4 after expansion until the support ring 44 abuts against the bottom wall of the tank body. At this point, the support plate 4 can no longer move and supports the rubber inner liner 3, and the air pressure in the air chamber 23 no longer increases. Therefore, this design does not impose any directional limitations on the actual installation of the water storage tank.
