Description

Technical Field

[0001] The utility model belongs to the technical field of pressure tank production, and particularly relates to a tightening tool for welding a pressure tank body and a head. Background Art

[0002] A pressure tank is a pressure vessel used to store and process gases or liquids. It primarily utilizes the different properties of water and gas, using a process of gas compression and expansion to balance the water volume and pressure in the system. When the water pressure in the system increases, the gas in the pressure tank is compressed, storing additional water. When the water pressure drops, the gas expands, releasing the stored water, thereby maintaining a stable system pressure. This operating principle not only helps prevent frequent opening of the safety valve and frequent replenishment of the automatic water supply valve, but also effectively balances water volume and pressure, preventing excessive pressure fluctuations in the system. The pressure tank operates automatically, minimizing pressure fluctuations, ensuring safety, reliability, energy conservation, and economical efficiency.

[0003] The production of pressure tanks is mainly made by welding the tank body and the heads at both ends. Because the pressure tank has extremely high requirements for sealing, only by tightening the tank body and the head during the welding process can the welding quality of the weld between the tank body and the head of the pressure tank be guaranteed, thereby ensuring the sealing of the pressure tank.
