JB/2205—20
This standard is the revision of the JB/2205—20
. The original standard is revised as follows: The main differences between this standard and JB/2205—20
are as follows: 1. The nominal lift of valve 1 is 1.6MPa and 2.5MPa, and the nominal diameter is DN200, DN250, DN30U, etc. The station length is 550, 600mm, and the leakage structure can be selected. Select the appropriate structure length. 2. Make appropriate adjustments to the structure length tolerance and reduce it by (0.3-0.5) mm. This standard replaces 2205-77 from the date of this standard. This standard will be submitted to the National Standardization Technical Committee for approval. The minor revision units are: Shenyang Yanmen Research Institute and Shanghai General Research Institute. The main revision persons of this standard are: Zheng Yunhai and Kong Tilong. Scope
