Description

Technical Field

[0001] The present application relates to the technical field of wall-mounted boiler equipment, and in particular to a double-water-tank wall-mounted boiler. Background Art

[0002] With the growing demand for hot water supply in modern families, wall-mounted boilers, as an efficient and energy-saving hot water and heating equipment, have become the first choice for many families.

[0003] However, with the continuous technological upgrade of household water supply systems, water heating systems generally increase water pressure and flow rate in order to improve heating efficiency, resulting in an expansion of the range of system pressure fluctuations, that is, the difference between the maximum and minimum fluctuations becomes larger. Traditional wall-mounted boilers use expansion water tanks to alleviate system pressure fluctuations to ensure the stable operation of the heating system. Existing expansion water tanks are difficult to adapt to system pressure fluctuations with large differences. Summary of the invention

[0004] In order to improve the problem that the expansion water tank of the existing wall-mounted boiler is difficult to adapt to the system pressure fluctuation with a large difference, the present application provides a double-water-tank wall-mounted boiler.

[0005] The double water tank wall-mounted boiler provided in this application adopts the following technical solution: A double water tank wall-mounted boiler, comprising: A first water tank is fixedly provided with a pressure bag, the outer wall of the pressure bag is fixedly connected to the inner wall of the first water tank, and an opening is opened on one side of the first water tank, and the opening is used to make the pressure bag protrude from the first water tank; The buffer bag is connected to the water pipe and is used to buffer the water pipe. One end of the buffer bag is connected to the opening.

[0006] By adopting the above technical solution, the first water tank can fix the pressure bladder, and an opening is provided on one side of the first water tank. The opening allows the pressure bladder to protrude from the first water tank and interact with the buffer bladder. The buffer bladder is connected to the opening of the first water tank and the water pipe, so that the buffer bladder can directly respond to system pressure fluctuations in the water pipe, and when the system pressure fluctuations are small, the part of the pressure bladder protruding from the first water tank is used to buffer the system pressure fluctuations. When the system pressure fluctuates, the pressure bladder is squeezed into the first water tank to buffer the system pressure fluctuations, thereby reducing the impact of the system pressure fluctuations on the wall-mounted boiler and the entire heating system, improving the stability and safety of the system, and improving the problem that the expansion water tank of the existing wall-mounted boiler is difficult to adapt to system pressure fluctuations with large differences.

[0007] Preferably, the pressure bag is filled with gas.

[0008] By adopting the above technical solution, when the system pressure increases, the water in the water pipe will compress the gas in the pressure bag and enter the bag; when the system pressure decreases, the gas in the bag will push the water in the bag back into the system, keeping the system pressure relatively stable.

[0009] Preferably, the pressure bladder and the buffer bladder are both rubber bladders.

[0010] By adopting the above technical solution, the rubber material, due to its good elasticity and durability, enables the pressure bladder and the buffer bladder to withstand long-term water pressure changes without rupture or damage.

[0011] Preferably, it further includes a second water tank, which is fixedly connected to the first water tank, and is fixedly connected to an end of the buffer bag away from the opening, and the second water tank is used to accommodate the buffer bag.

[0012] By adopting the above technical solution, the second water tank protects the buffer bag from the influence of the external environment, such as direct physical impact.

[0013] Preferably, the second water tank is provided with an air pressure part, the air pressure part is arranged between the first water tank and the buffer bag, and the air pressure part is filled with gas.

[0014] By adopting the above technical solution, when the system pressure fluctuates, the gas in the air pressure part can be compressed or expanded by the buffer bag to balance the system pressure and maintain the stability of the system pressure.

[0015] Preferably, the air pressure of the pressure bag is lower than the air pressure of the air pressure part.

[0016] By adopting the above technical solution, the pressure bladder and the air pressure part can create a pressure gradient. When the system pressure fluctuates, the pressure bladder is more sensitive to smaller system pressure fluctuations, so that the pressure bladder can buffer smaller system pressure fluctuations and the air pressure part can buffer larger system pressure fluctuations.

[0017] Preferably, the wall thickness of the pressure bladder is smaller than the wall thickness of the buffer bladder.

[0018] By adopting the above technical solution, the pressure bladder has a thinner wall thickness and can be more sensitive to system pressure fluctuations, ensuring that the pressure bladder can preferentially respond to smaller system pressure fluctuations. The buffer bladder has a thicker wall thickness and can withstand larger deformation and physical impact while ensuring the existence of a pressure gradient.

[0019] Preferably, the second water tank is further provided with a gas charging port, the gas charging port is communicated with the air pressure part, and the gas charging port is used to replenish gas to the air pressure part.

[0020] By adopting the above technical solution, the second water tank can inflate the air pressure part through the inflation port, maintain the pressure of the air pressure part, and avoid the pressure drop of the air pressure part due to gas leakage or other reasons.

[0021] Preferably, the gases in the pressure bag and the air pressure part are both nitrogen.

[0022] By adopting the above technical solution, the stability of nitrogen enables the pressure bag and the air pressure part to work stably under different temperature and pressure conditions, reducing the pressure changes caused by gas reactions.

[0023] Preferably, it further comprises a furnace body, which is connected to the water pipe and is used to heat the water in the water pipe.

[0024] By adopting the above technical solution, the furnace body can heat the water in the water pipe to ensure the supply of heating and hot water.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The first water tank can fix the pressure bag. An opening is provided on one side of the first water tank. The opening enables the pressure bag to protrude from the first water tank and interact with the buffer bag. The buffer bag is connected to the opening of the first water tank and the water pipe, so that the buffer bag can directly respond to the system pressure fluctuation in the water pipe, and when the system pressure fluctuation is small, the part of the pressure bag protruding from the first water tank can be used to buffer the system pressure fluctuation. When the system pressure fluctuates, the pressure bag is squeezed into the first water tank to buffer the system pressure fluctuation, thereby reducing the impact of the system pressure fluctuation on the wall-mounted boiler and the entire heating system, improving the stability and safety of the system, and improving the problem that the expansion water tank of the existing wall-mounted boiler is difficult to adapt to the system pressure fluctuation with a large difference; 2. When the system pressure increases, the water in the water pipe will compress the gas in the pressure bag and enter the bag; when the system pressure decreases, the gas in the bag will push the water in the bag back into the system, keeping the system pressure relatively stable; 3. Due to its good elasticity and durability, the rubber material enables the pressure bladder and the buffer bladder to withstand long-term water pressure changes without rupture or damage.

[0028] The following is combined with Figure 1-6 This application is described in further detail.

[0029] The present application embodiment discloses a double water tank wall-mounted boiler. Figure 1 and Figure 2 The double water tank wall-mounted boiler includes a second water tank 2, a first water tank 1 and a buffer bag 3.

[0030] like Figure 3 and Figure 4 As shown, one end of the second water tank 2 is fixedly connected to the water pipe 6 by means of a joint, a pipe, a flange and / or bolts, and the end of the second water tank 2 away from the water pipe 6 is open, and the first water tank 1 is fixedly arranged on the end of the second water tank 2 away from the water pipe 6 by welding or the like to close the end of the second water tank 2 away from the water pipe 6; the second water tank 2 forms a whole by being connected to the first water tank 1.

[0031] In the embodiment of the present application, a pressure bag 12 is fixedly arranged in the first water tank 1 by materials or structures such as adhesives, and the second water tank 2 protects the buffer bag 3 from the influence of the external environment, such as direct physical impact, etc. The outer wall of the pressure bag 12 is fixedly connected to the inner wall of the first water tank 1, and a circular opening 11 is opened on the side of the first water tank 1 close to the second water tank 2, and the opening 11 is used for the pressure bag 12 to protrude from the first water tank 1, and a buffer bag 3 is arranged in the second water tank 2, and one end of the buffer bag 3 is connected to the water pipe 6 through a joint, a pipe or a flange of the second water tank 2, and the end of the buffer bag 3 away from the water pipe 6 is open, and the end of the buffer bag 3 away from the water pipe 6 is fixedly connected to the first water tank 1 through a flange, a clamp and or a metal ring and connected to the opening 11 of the first water tank 1, so that when the system pressure fluctuates, the pressure bag 12 can directly respond to the system pressure fluctuation and buffer the system pressure fluctuation.

[0032] The opening 11 allows the pressure bladder 12 to protrude from the first water tank 1 and directly interact with the water in the buffer bladder 3. The buffer bladder 3 is connected to the opening 11 of the first water tank 1 and the water pipe 6, so that the pressure bladder 12 can directly respond to system pressure fluctuations in the water pipe 6, and when the system pressure fluctuation is small, the system pressure fluctuation is buffered by the portion of the pressure bladder 12 protruding from the first water tank 1. When the system pressure fluctuates, the system pressure fluctuation is buffered by the deformation of the pressure bladder 12, thereby reducing the impact of the system pressure fluctuation on the wall-mounted boiler and the entire heating system, improving the stability and safety of the system, and improving the problem that the expansion water tank of the existing wall-mounted boiler is difficult to adapt to system pressure fluctuations with large differences.

[0033] Specifically, the pressure bag 12 is filled with gas. When the system pressure increases, the water in the water pipe 6 will flow into the buffer bag 3, causing the pressure in the buffer bag 3 to increase. At this time, the air pressure in the pressure bag 12 is less than the pressure in the buffer bag 3, causing the pressure bag 12 to deform or be squeezed into the first water tank 1, thereby relieving the system pressure; when the system pressure decreases, the air pressure in the pressure bag 12 is greater than the pressure in the buffer bag 3, causing the pressure bag 12 to protrude from the first water tank 1 and push the water in the buffer bag 3 back into the system, thereby keeping the system pressure relatively stable.

[0034] In the embodiment of the present application, the pressure bladder 12 and the buffer bladder 3 are both rubber bladders. Due to the good elasticity and durability of the rubber material, the pressure bladder 12 and the buffer bladder 3 can withstand long-term water pressure changes without rupture or damage.

[0035] like Figure 4 As shown, an air pressure part 5 is provided between the second water tank 2 and the buffer bag 3. The air pressure part 5 is filled with gas. The gas in the air pressure part 5 can be compressed or expanded by the buffer bag 3 to balance the system pressure and maintain the stability of the system pressure.

[0036] In the embodiment of the present application, the air pressure of the pressure bag 12 is lower than the air pressure of the air pressure part 5. The pressure bag 12 and the air pressure part 5 can create a pressure gradient. When the system pressure fluctuates, the pressure bag 12 is more sensitive to smaller system pressure fluctuations, thereby enabling the pressure bag 12 to buffer smaller system pressure fluctuations and enabling the air pressure part 5 to buffer larger system pressure fluctuations.

[0037] In the embodiment of the present application, the wall thickness of the pressure bladder 12 is smaller than the wall thickness of the buffer bladder 3. The thinner wall thickness of the pressure bladder 12 can be more sensitive to system pressure fluctuations, ensuring that the pressure bladder 12 can preferentially respond to smaller system pressure fluctuations. The thicker wall thickness of the buffer bladder 3 can withstand larger deformation and physical impact while ensuring the existence of a pressure gradient.

[0038] Specifically, when the system pressure increases and the pressure bag 12 is completely deformed, when the pressure inside the buffer bag 3 is relatively high, the buffer bag 3 is deformed to relieve the system pressure; when the system pressure decreases, the pressure inside the buffer bag 3 is less than the pressure of the air pressure part 5, thereby driving the buffer bag 3 to reset and push the water in the buffer bag 3 back to the system, keeping the system pressure relatively stable.

[0039] In the embodiment of the present application, the gases in the pressure bag 12 and the air pressure part 5 are both nitrogen. The stability of nitrogen enables the pressure bag 12 and the air pressure part 5 to operate stably under different temperature and pressure conditions, reducing pressure changes caused by gas reactions.

[0040] like Figure 4 As shown, the second water tank 2 is also provided with an air filling port 7, which is connected to the air pressure part 5. Maintenance personnel can inflate the second water tank 2 through the air filling port 7 to ensure the pressure of the air pressure part 5 and avoid the pressure drop of the air pressure part 5 due to gas leakage or other reasons.

[0041] like Figure 2 and Figure 4 As shown, the furnace body 4 is connected to the water pipe 6, and the furnace body 4 is used to heat the water pipe 6 to ensure the supply of heating and hot water.

[0042] For example, Figure 1 and Figure 2 As shown, in the embodiment of the present application, the second water tank 2, the first water tank 1 and the buffer bag 3 and other structures are all arranged in the furnace body 4, and the buffer bag 3 is used to adjust the pressure fluctuation of the furnace body 4, thereby adjusting the system fluctuation.

[0043] For example, Figure 5 and Figure 6 As shown, in another embodiment of the present application, structures such as the second water tank 2, the first water tank 1 and the buffer bag 3 are all arranged outside the furnace body 4 to adjust the pressure of the entire system.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
