JB/T 2231.5-1999 Reciprocating piston compressor parts Part 5: Valve installation dimensions

JB/T 2231.5-1999 This standard is a revision of ZB J72 012-87 "Installation Dimensions of Reciprocating Piston Compressor Valves". The main technical content changes are as follows: - Added "reference standard" GB 1801 "Tolerance and fit dimensions to 500mm hole, shaft tolerance zone and fit"; - In order to prevent the wrong installation of inlet and exhaust valves, the relevant safety requirements for valve installation are specified. This standard is the fifth part of the JB/T 2231 "Reciprocating Piston Compressor Parts" series of standards, which includes the following five independent components: JB/T 2331.1: Shaft and pin outer dimensions JB/T 2331.2: Cylinder diameter JB/T 2331.3: Thin-walled bearings JB/T 2331.4: Ring valve discs JB/T 2331.5: Valve installation dimensions This standard specifies the installation dimension requirements of ring and mesh round valves for reciprocating piston compressors. This standard applies to annular and mesh valves for reciprocating piston compressors. This standard was first issued in 1977 and revised for the first time in 1987.

The tolerance of the gas adjustment women's clothing should be in accordance with the requirements of 22 specified in 1X1-1979. The total tolerance of the sample key should be 3 with the general promotion number. Use the design of the six-space 4-gas test that can increase the need for gas solution or point-spring front shadow. The steel that is assembled is assembled due to the sparse state and the installation effect is reversed for the whole air intake and exhaust. The air is used in the outside size (). If there is a complete difference in the purchase flow of related parts, the air selection on the same machine will not be issued.
