Abstract
A pressure tank includes a metallic vessel, a plastic liner received in the metallic vessel, a flexible diaphragm, two connectors and a nozzle coupled to the nipples respectively. The metallic vessel includes upper and lower shells. The upper shell defines a first planar area on a side thereof and a second planar area on a top thereof. The lower shell defines a third planar area therebottom. The flexible diaphragm divides the metallic vessel into a storage space and a pneumatic room. Each of the connectors includes a nipple and an anti-leak assembly. The nipples of the connectors are mounted on the side and top of the upper shell respectively and are in communication with the storage space. The two anti-leak assemblies provide leakproof connection between the nipples and the plastic liner. Additionally, the nozzle is mounted on the third planar area to be in communication with the pneumatic room.
