Description

Technical Field

[0001] This utility model relates to the field of hot water storage equipment technology, and more specifically, to a flexible inner liner pressure-bearing hot water storage tank. Background Technology

[0002] In today's society, with people's increasing demands for quality of life, hot water supply plays a vital role in daily life and industrial production. As a key piece of equipment for hot water storage and supply, the performance of hot water storage tanks directly affects the stability and reliability of hot water supply. Traditional hot water storage tanks have many problems that need to be solved in the design and use process, which limit their widespread application and long-term stable operation in different scenarios.

[0003] Traditional hot water storage tanks typically use rigid materials for their inner tanks, such as stainless steel and carbon steel. While rigid inner tanks offer some strength and corrosion resistance, their performance is significantly inadequate when faced with pressure changes and temperature fluctuations during hot water storage. When the amount of hot water in the tank increases or the temperature rises, the inner tank bears considerable pressure. Lacking an effective buffering mechanism, rigid inner tanks are prone to localized stress concentration, which can lead to cracks, deformation, or even rupture after prolonged use. This severely impacts the lifespan and safety of the hot water storage tank. Once the inner tank is damaged, hot water leakage not only wastes water resources but may also damage the surrounding environment and equipment, and even cause safety accidents.

[0004] Therefore, this application provides a flexible inner liner pressure-bearing hot water storage tank to solve the problems mentioned in the background art. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a flexible inner liner pressure-bearing hot water storage tank. By setting a pressure-bearing ring, it can enable the flexible inner liner to have a strong buffering effect when storing water, thereby improving the pressure-bearing performance of the flexible inner liner.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A flexible-lined pressurized hot water storage tank includes a main body with an inlet pipe at the upper end and an outlet pipe at the lower end. A flexible inner liner is fixedly connected inside the main body. Multiple evenly distributed pressure-bearing rings are arranged between the flexible inner liner and the inner wall of the main body. Each pressure-bearing ring includes a connecting ring connected to the inner wall of the main body. Multiple evenly distributed elastic contact rods are embedded in the connecting rings. Each elastic contact rod is connected to the flexible inner liner by a flexible connecting rod. By setting the pressure-bearing rings, the flexible inner liner can have a strong buffering effect when storing water, thus improving the pressure-bearing performance of the flexible inner liner.

[0010] As a further improvement of this utility model, the flexible inner liner is made of fluororubber, silicone rubber or heat-resistant polyurethane material. These materials have good temperature resistance, corrosion resistance and flexibility, can adapt to the storage environment of hot water, and are not prone to large stress when the temperature changes.

[0011] As a further improvement of this utility model, the elastic contact rod is made of an elastic metal material and its surface is covered with a rubber layer. When the flexible inner liner expands or contracts due to water filling or temperature changes, the elastic contact rod can deform accordingly, avoiding additional stress on the flexible inner liner and ensuring the normal operation of the flexible inner liner.

[0012] As a further improvement of this utility model, the outer end of the connecting ring is drilled with a mounting hole, and a screw is threaded into the mounting hole. By setting the mounting hole and the screw, the connecting ring can be easily disassembled and replaced from the main body of the water storage tank, thereby improving the work efficiency of technicians.

[0013] As a further improvement of this utility model, both the inlet pipe and the outlet pipe are equipped with one-way valves. By setting the one-way valves, water backflow can be prevented, ensuring the normal supply of hot water.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] 1. This device uses multiple evenly distributed pressure-bearing rings between the flexible inner liner and the inner wall of the water storage tank. The elastic contact rods and flexible connecting rods of the pressure-bearing rings work together. When the flexible inner liner expands or contracts due to water filling or temperature changes, the elastic contact rods can deform accordingly, effectively buffering the pressure on the inner liner, avoiding additional stress on the flexible inner liner, greatly improving the pressure-bearing performance of the flexible inner liner, extending the service life of the flexible inner liner, and reducing the equipment failure rate and maintenance costs.

[0017] 2. The flexible inner tank of this device is made of fluororubber, silicone rubber, or heat-resistant polyurethane. These materials have excellent temperature resistance, corrosion resistance, and flexibility, which can adapt well to the hot water storage environment. They are not prone to generating large stresses when the temperature changes, ensuring the stability of the flexible inner tank under various working conditions. The elastic contact rod is made of elastic metal material and covered with a rubber layer, which not only ensures the strength of the elastic contact rod, but also further reduces the stress impact on the flexible inner tank, ensuring the normal operation of the flexible inner tank and improving the reliability and stability of the entire hot water storage tank.

[0018] 3. The device has a mounting hole drilled at the outer end of the connecting ring and a threaded screw connected to it. This design allows the connecting ring to be easily removed and replaced from the main body of the water storage tank, greatly improving the work efficiency of technicians and reducing maintenance difficulty and cost. At the same time, the one-way valves installed on the inlet and outlet pipes effectively prevent water backflow, ensuring the normal supply of hot water, improving the stability and reliability of the entire hot water supply system, and providing users with a better hot water experience.

[0027] Example:

[0028] Please see Figures 1-3 A flexible inner liner pressurized hot water storage tank includes a storage tank body 1, an inlet pipe 2 installed at the upper end of the storage tank body 1, an outlet pipe 3 installed at the lower end of the storage tank body 1, a flexible inner liner 4 fixedly connected inside the storage tank body 1, and multiple evenly distributed pressure-bearing rings 5 ​​arranged between the flexible inner liner 4 and the inner wall of the storage tank body 1. Each pressure-bearing ring 5 includes a connecting ring 6 connected to the inner wall of the storage tank body 1, and multiple evenly distributed elastic contact rods 7 are embedded in the connecting ring 6. Each elastic contact rod 7 is connected to the flexible inner liner 4 by a flexible connecting rod 8. By setting the pressure-bearing rings, the flexible inner liner can have a strong buffering effect when storing water, thereby improving the pressure-bearing performance of the flexible inner liner.

[0029] Please see Figures 1-3 The flexible inner liner 4 is made of fluororubber, silicone rubber or heat-resistant polyurethane. These materials have good temperature resistance, corrosion resistance and flexibility, and can adapt to the storage environment of hot water. They are also less likely to generate large stress when the temperature changes. The elastic contact rod 7 is made of elastic metal material and is covered with a rubber layer. When the flexible inner liner 4 expands or contracts due to water filling or temperature changes, the elastic contact rod 7 can deform accordingly, avoiding additional stress on the flexible inner liner 4 and ensuring the normal operation of the flexible inner liner 4.

[0030] Please see Figures 1-3The outer end of the connecting ring 6 has a mounting hole, and a screw 601 is threaded into the mounting hole. By setting the mounting hole and the screw 601, the connecting ring 6 can be easily removed and replaced from the main body of the water storage tank 1, thereby improving the work efficiency of technicians. One-way valves are set on both the inlet pipe 2 and the outlet pipe 3. By setting the one-way valve, water backflow can be prevented and the normal supply of hot water can be guaranteed.

[0031] Working principle: When technicians use this device, hot water enters the main body 1 of the water storage tank through the inlet pipe 2. As the water gradually increases, the flexible inner liner 4 compresses the pressure ring 5, thereby causing the flexible inner liner 4 to compress the elastic contact rod 7 through the flexible connecting rod 8. This causes the elastic contact rod 7 to bend and deform towards the main body 1 of the water storage tank, thereby improving the buffering effect of the flexible inner liner 4. Compared with the prior art, this utility model can achieve a stronger buffering effect when storing water by setting the pressure ring, thus improving the pressure bearing performance of the flexible inner liner.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
