Preface
This document complies with the provisions of GB/T 1:1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents"
Drafting:
This document replaces GB/T 24671-2009 "Graphic symbols for pressure-bearing irrigation systems of agricultural irrigation equipment" and is consistent with GB/T 24671-2009
In comparison, in addition to structural adjustments and editorial changes, the main technical changes are as follows:
a) Changes to the “Basic Rules” (see Chapter 4, Chapter 3 of the:2009 edition);
b) Changed the graphical symbol of “main (trunk) pipeline” (see 5:1, 4:1 of the:2009 edition);
c) Change "branch (branch) pipeline" to "branch pipeline" and divide it into "branch (secondary) pipeline" and "branch (third-level) pipeline" (see 5:2,:2009 edition
4:2);
d) Change "pipeline to be added later (planned)" to "pipeline to be expanded (planned)" (see 5:3, 4:3 of the:2009 version);
e) Change "existing pipelines to be utilized" to "existing pipelines to be used" (see 5:4, 4:4 of the:2009 version);
f) Change "pipe connection" to "pipe joint" (see 5:5, 4:5 of the:2009 version);
g) Added the graphic symbol of eccentric reducer (see 5:10:2);
h) Added replacement pipeline graphical symbols (see 5:11:2);
i) Change "failure to open valve" to "failure to open valve (normally open)"; change "failure to close valve" to "failure to close valve (normally closed)";
"Failure to remain in position valve" is changed to "valve to remain in failure state" (see 7:2:1, 6:2:1 of the:2009 version);
j) The graphical symbol of the manual valve has been changed (see 7:2:2, 6:2:2 of the:2009 version);
k) Added check valve flow direction requirements (see 7:3:1);
l) Change "duplex multi-function intake and exhaust valve" to "dual/triple function intake and exhaust valve" (see 7:3:2:3, 6:3:2:3 of the:2009 version);
m) Added the graphical symbol of the bottom valve (see 7:3:6);
n) Added graphical symbols for pumps (see 8:1:1, 8:1:2, 8:1:3, 8:1:4, 8:1:5);
o) Added graphical symbols for water meters (see 9:2:1, 9:2:2, 9:2:3, 9:2:4);
p) Added sand filter graphic symbol (see 11:3):
