介绍核一级电动截止阀样机鉴定试验目的、试验内容、试验装置、测量参数、试验方法等内容。试验结果表明:试验前阀门阀座、阀杆密封无泄漏,冷态开启、关闭行程时间均为11 s;在热态寿命、热态循环、冷热交变及流体阻断试验过程中阀门开启、关闭正常,开启、关闭行程时间均为11 s;试验后阀门阀座密封10 min泄漏12滴水,阀杆密封无泄漏,冷态开启、关闭行程时间均为11 s,各项试验数据表明阀门满足设计要求。
The purpose, contents, test equipment, measurement parameters, test methods and so on of the purpose of the identification test of nuclear-level electric globe valve prototype are introduced. The test results show that: before the test, the valve seat and the stem seal have no leakage, and the opening and closing stroke in cold state are both 11 s; during the hot state, hot state, hot and cold alternating and fluid blocking test, the valve is open , Closed normal, open, closed travel time is 11 s; valve seat seal 10 min after the test leak 12 drops of water, the stem seal leak, cold open, closing travel time is 11 s, the test data show that the valve Meet the design requirements.
