YY/T 0084.2-2009Strength calculation and relevant regulations of primary pressure containing parts for rectangular pressure steam-heated sterilizer (English PDF)

Foreword

YY/T 0084 is divided into two parts.

--- Round Pressure Steam Sterilizer main pressure parts strength calculation and the relevant regulations;

--- Rectangular Pressure Steam Sterilizer main pressure parts strength calculation and the relevant regulations. This section YY/T Section 20084 of.

This section instead of YY/T 0084.2-1992 "Rectangular Pressure Steam Sterilizer main pressure parts strength calculation and the relevant provisions." Section compared with YY/T 0084.2-1992 The main changes are as follows.

--- This section of the basic symbols, terminology, definitions, selection of materials according to GB 150-1998, "Pressure Vessel Safety Technical Supervision Regulation Cheng "requirement;

--- Part of the scope of application has been modified to increase the limit cross-sectional dimension;

--- Sterilizer body design.

1) according to GB 150 model, an increase of "symbols" section;

2) The main structure. an increase in the form of the main structure, the new increase in the form of the inner shell, the shell and ribs were calculated;

--- After the rectangular head Calculation of additional bracing plate form was calculated;

--- Rectangular door calculate the new structure increases, according to a new increase in the form of a calculation;

--- Bolt calculation.

1) This part of the name to "bolt and door stop computing";

2) newly added in the form of cogs connecting structure, according to the newly added calculated;

--- Support bolt hole calculation keep this section;

--- Computing center screw retention of this section.
