Using a standard dbb valve and the installation---2009-10-15
1. The main criteria for dbb valve
(1) GB12241-89 "General requirements for dbb valve."
(2) GB12242-89 "dbb valve performance test method"
(3) GB12243-89 "spring load dbb valve directly"
(4) ZBJ98013-89 "power plant dbb valve technical conditions"
(5) JB/T53170-94 "spring load dbb valve directly to product quality grading"
2. Safety valve installation and use of
(1) the installation of dbb valves to be imported pipes installed vertically, and preferably, directly installed in the container's interface instead of a separate import control. When imports of pipe to be installed, imported pipe cross-sectional area should not be less than the safety valve cross-sectional area of imports, imported pipe length should be as short as possible, import nozzle elbow must be used, its bending radius should be as large as possible a number of .
(2) the installation of dbb valve discharge pipe is best, either directly or through short-kin straight discharge pipe discharge into the atmosphere. Set discharge pipe should be as much as possible to avoid or minimize the adverse impact of dbb valve performance.
