Abstract

The invention provides a pressure tank, and belongs to the technical field of pressure tanks. The pressure tank solves the problem that an air bag of an existing pressure tank is prone to damage. Thepressure tank comprises a shell and an air bag arranged in the shell. The air bag divides a cavity in the shell into an air cavity and a water cavity which are not in communication. An air nozzle anda water inlet connector are arranged in the shell. The air nozzle communicates with the air cavity. The water inlet connector communicates with the water cavity. The outer side wall of the air bag isprovided with a protruding first abutting part corresponding to the air nozzle, and the inner side wall of the air bag is provided with a protruding second abutting part corresponding to the water inlet connector. The pressure tank has the advantages that the air bag is not prone to damage, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of pressure tanks, and relates to a pressure tank, in particular to a water pump pressure tank. Background technique [0002] The pressure tank is used in the closed water circulation system to balance the water volume and pressure, avoid frequent opening of the safety valve and frequent replenishment of the automatic water replenishment valve. The water pump is a common equipment used to pump water. When the water pump pumps water, the water pressure inevitably fluctuates. Therefore, a pressure tank is often installed on the water pump to balance the water pressure, prevent the vibration of the water pump cylinder, and improve the working life of the water pump. [0003] Existing pressure tanks, such as Chinese patent documents disclose a pressure tank [application number: 201420680367.8; authorized announcement number: CN204253345U], which includes a tank body and a leather bag, and a flange cover for fixi...
