Description

Technical Field

[0001] The utility model belongs to the technical field of expansion water tanks, and particularly relates to a square water tank. Background Art

[0002] Expansion water tanks are generally circular or rectangular. Due to the thermal expansion and contraction of water in the heating system, when the hot water temperature rises, the water volume in the system increases. When there is no place to accommodate this part of the expanded water volume, the water pressure in the heating system increases, which will affect the normal operation. The expansion water tank accommodates the water expansion volume of the system, which can reduce the water pressure fluctuation caused by the expansion of water in the system, and improve the safety and reliability of the system operation. When the system leaks or the system temperature drops due to some reason, the water level of the expansion water tank drops to replenish water for the system. The expansion water tank can also play a role in stabilizing the pressure of the system and discharging the air released during the heating process of water. However, the traditional water tank wall is in a thin-wall shape, which reduces the overall structural strength of the water tank. It is easy to deform when being bumped or impacted during handling, assembly or production, thus affecting the continued use of the water tank. Content of the Utility Model
