The invention discloses a double protection multistage pressure relief flange used for a low-pressure boiler and relates to an accessory of pressure boiler equipment. The double protection multistage pressure relief flange consists of a flange and one-way pressure relief valves and is characterized in that more than two pressure relief channels are formed in the flange, and more than two one-way pressure relief valves are mounted in each pressure relief channel. Each pressure relief channel comprises a connecting channel A, an annular channel A, a connecting channel B, an annular channel B and a pressure discharge channel, wherein the connecting channels A and the inner end of the flange are connected with the annular channels A; the annular channels A are connected with the annular channels B by the connecting channels B; and the annular channels B are communicated with the outer end of the flange by the pressure discharge channels. The one-way pressure relief valves are mounted in annular channels A and the annular channels B of the pressure relief channels respectively, and are sealed through sealing members. The double protection multistage pressure relief flange for the low-pressure boiler has the characteristics of novel structure, simplicity and convenience in processing, convenience in use, safety, reliability, convenience in maintenance and replacing, and the like, and integrates economical efficiency and practicability.
Description
technical field [0001] The multi-stage pressure relief flange with double protection for a low-pressure boiler according to the invention relates to an auxiliary accessory of pressure boiler equipment. Background technique [0002] At present, flanges are used to connect boilers with external equipment or pipelines. When the pressure is too high, dangers such as loosening and air leakage are likely to occur at the connecting flanges. In view of the problems existing in the prior art mentioned above, it is very necessary to study and design a new type of multi-stage pressure relief flange with double protection for low-pressure boilers, so as to overcome the problems existing in the prior art. Contents of the invention [0003] In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to study and design a novel multi-stage pressure relief flange with double protection for low-pressure boilers. It is used to solve the existi...
