LUO Sheng. RETROFITTING OF AUXILIARY VALVE FOR SOLENOID BLOWOUT VALVES[J]. Thermal power generation, 2004, (5): 79-80. DOI: 10.19666/j.rlfd.2004.05.026.
Through analysing the causes leading to auxiliary valve leakage for the solenoid blowout valves
corresponding retrofitting measures have been put forward
The said measures are as follows: (1) retrofitting clack structure of the auxiliary valve; (2) changing position of the auxiliary valve;(3) altering the test method; (4) strengthening inspection in starting up of the boiler. The abovementioned measures have been taken for solenoid blowout valves on boiler NO.3 and NO.4 in Zhujiang Power Co Ltd. The results of operation in more than one year show that the effectiveness of retrofitling is good
leakage of the auxiliary valve having not occurred again
