Abstract
A tank formed using two half shells may be used as an expansion tank, expansion equalizer, pressurized fluid buffer tank or the like. Two half shells are provided with a projecting flared profile having a first section angled outwardly from the wall and a flange directed perpendicularly outwardly. The tank halves are joined by abutting the flanges, and the angularly offset sections adjacent the flanges form a bearing area or seat for sealing with an internal diaphragm. The diaphragm separates the tank into sections and is arranged at its end to receive and positively hold a ring of a profile complementary to the internal profile defined by the outwardly flaring sections adjacent the flanges of the tank. The flanges can be folded over one another and against the wall of the tank to physically attach the half shells.
Claims6
An improved tank of the type including half-shells assembled together with a diaphragm separating an internal space into fluid chambers and a connecting ring, comprising:
- two half-shells each having edge portions projecting outwardly beyond a line defined by lateral walls of the half shells defining a flared profile, each half shell having a first section offset outwardly and a flange consecutive to the offset section and directed perpendicularly outwardly, the two half shells abutting on their respective flanges and the consecutive sections forming a bearing seat for the diaphragm, the diaphragm movably separating the tank into the fluid chambers, said diaphragm being arranged on its open end to receive and hold a ring having a profile complementary to a V-shaped profile defined by the two consecutive sections, the flanges having a long radial extension and being assembled together by being folded over one another and against said half shells.
