Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces CJ/T 219-2005 "Hydraulic Control Valve", compared with CJ/T 219-2005, except for editorial modification of the main technology The changes are as follows. --- Modify the nominal size and nominal pressure range; --- Modify "adjustable pressure relief valve" as "split pilot decompression regulator valve"; --- Removed the terms slow closing muffler check valve, water pump control valve and emergency stop valve; --- Modify "differential pressure bypass bypass valve" as "pressure differential control valve"; --- Modify the structure type, remove the slow closing anechoic check valve, pump control valve and emergency stop valve, new Y-type diaphragm main valve; --- Added coating and appearance requirements; --- Added hydraulic loss and low pressure water seal test requirements; --- Increased the requirements for the normal opening and closing of differential float valves; --- Modified pressure relief/pressure valve technical performance parameters; --- Revised inspection item list. This standard is proposed by the Institute of Standardization of Housing and Urban-Rural Development Standards. This standard is under the jurisdiction of the Ministry of Housing and Urban-Rural Construction Water Supply and Drainage Standardization Technical Committee. This standard was drafted by.
