Abstract

The invention relates to the technical field of manufacturing and production of pressure containers, in particular to a diaphragm air pressure tank and a processing technology thereof. The diaphragm air pressure tank comprises a steel air tank body and a rubber air bag; the rubber air bag is located inside the steel air tank body, a pressure chamber is formed between the steel air tank body and the rubber air bag, a water storage chamber is formed by the rubber air bag, a fixing structure for fixing the rubber air bag is arranged on the steel air tank body, the fixing structure comprises a flange plate and a flange cover, the rubber air bag is located between the flange plate and the flange cover, a sealing structure for sealing a gap between the fixing structure and the rubber air bag isarranged in the fixing structure, the sealing structure comprises an air sealing layer used for sealing a gap of the pressure chamber at the fixing structure and a water sealing layer used for sealinga gap of the water storage chamber at the fixing structure, and the water sealing layer is fixedly connected between the rubber air bag and the flange cover. The diaphragm air pressure tank and the processing technology thereof have the effect of being good in sealing performance.

Description

technical field [0001] The invention relates to the technical field of pressure vessel production, in particular to a diaphragm pressure tank and its processing technology. Background technique [0002] Air pressure tanks are widely used in central air conditioners, boilers, water heaters, frequency conversion, and constant pressure water supply equipment. The automatic expansion and contraction of the airbag will have a certain buffering effect on the change of the water pressure, which can ensure the stability of the water pressure of the system, and the water pump will not be opened frequently due to the change of the pressure. [0003] In the prior art, a Chinese patent document with the authorized announcement number CN205530473U records a new type of vertical diaphragm pressure tank, which is composed of a steel shell and a highly elastic natural rubber air bag. The steel shell is supported by a support , flange flange cover, fastening bolt, flange flange, backing pla...
