Description

Technical Field

[0001] The utility model relates to the technical field of buffer tanks, in particular to a diaphragm type buffer tank with a supporting structure. Background Art

[0002] Buffer tanks are primarily used to buffer pressure fluctuations in various systems, ensuring smoother operation. The buffering performance of the buffer tank is primarily achieved by compressing the compressed air within the tank. Buffer tanks come in two types: diaphragm and bladder types. They are widely used in applications such as water supply equipment and central air conditioning systems.

[0003] The diaphragm type buffer tank is provided with a diaphragm inside the tank body. The existing diaphragm type buffer tank and the diaphragm are generally installed on the inner wall of the buffer tank by the cooperation of a fixing ring and bolts. Under normal circumstances, the diaphragm naturally droops in the buffer tank, causing the edge of the diaphragm and the position where it cooperates with the fixing ring to be bent under stress for a long time, which makes it easy to crack, affecting the service life of the diaphragm. In addition, since the existing diaphragm is installed on the inner wall, if it is a split tank body, a sealing ring needs to be installed at the connection between the upper tank and the lower tank, which increases the cost. Therefore, an improved technology is urgently needed to solve this problem existing in the existing technology. Utility Model Content

[0024] The support assembly includes a orifice plate 15, a surrounding edge 16 and an outer folding edge 17. The orifice plate 15 is provided with a surrounding edge 16 on the periphery, and an outer folding edge 17 is provided on the upper part of the surrounding edge 16.
