一、概况内径1.8米,长16米,筒壁厚18毫米的蒸压釜。设计用蒸汽参数为14表压,250℃温度。设计用材料:法兰及釜圈用16Mn锻件,其余用16MnR钢板。蒸压釜外形如图1。图2(a)是釜体的端部及釜圈,图2(b)是釜盖及法兰。釜圈及法兰分别具有凹凸齿各30只,其形式与家用压力锅类似。密封面在图2(a)中d_1d_2d_3d_4槽内嵌入橡胶圈与图2(b)中ab面压紧。当釜内进入蒸汽并升压后,图2(a)中fg与图2(b)中hi两齿面互相压紧。
First, an overview of the inner diameter of 1.8 meters, 16 meters long, cylinder wall thickness of 18 mm autoclave. Design steam parameters of 14 gauge pressure, 250 ℃ temperature. Design Materials: Flange and kettle ring with 16Mn forgings, the rest with 16MnR steel. Autoclave appearance shown in Figure 1. Figure 2 (a) is the end of the kettle body and reactor ring, Figure 2 (b) is the kettle cover and flange. Kettle ring and flange, respectively, with the concave and convex teeth of the 30, its form and domestic pressure cooker similar. Sealing surface in Figure 2 (a) d_1d_2d_3d_4 groove embedded rubber ring and Figure 2 (b) ab surface compression. When the kettle into the steam and booster, fg in Figure 2 (a) and hi two tooth surfaces in Figure 2 (b) pressed together.
