Title
(EN) Water seal device for nuclear power plant voltage stabilizer and nuclear power plant voltage stabilizer
(ZH) 核电站稳压器水封装置及核电站稳压器
Abstract
(EN)
The invention discloses a water seal device for a nuclear power plant voltage stabilizer and the nuclear power plant voltage stabilizer. The water seal device comprises a voltage stabilizer upper seal head (1), a voltage stabilizer safety valve adapter tube (2) inserted into the voltage stabilizer upper seal head (1), a safety valve process pipe (3) used for connecting a voltage stabilizer safety valve with the voltage stabilizer safety valve adapter tube (2) as well as a water collecting cover (4) which is arranged on the inner side surface of the voltage stabilizer upper seal head (1) and covers a port in one end of the voltage stabilizer safety valve adapter tube (2). The water seal device can perform water seal on the port in one end, communicating with inner vapor phase of the voltage stabilizer, of the voltage stabilizer safety valve adapter tube, so that hydrogen in the inner vapor phase of the voltage stabilizer cannot leak through the voltage stabilizer safety valve; furthermore, the water collecting cover is arranged in the voltage stabilizer, layout space outside the voltage stabilizer is saved, and besides, with the adoption of high-temperature water seal, hydraulic load borne by a downstream discharge pipeline after the voltage stabilizer safety valve is switched on can be effectively reduced.

本发明公开了一种核电站稳压器水封装置及核电站稳压器。所述水封装置包括:稳压器上封头(1)、穿插设置在所述稳压器上封头(1)上的稳压器安全阀接管(2)、用于连接稳压器安全阀和所述稳压器安全阀接管(2)的安全阀工艺管(3)、以及设置在所述稳压器上封头(1)内侧表面上且罩住所述稳压器安全阀接管(2)一端端口的集水罩(4)。本发明提供的水封装置可以水封稳压器安全阀接管与稳压器内部汽相连通的一端端口,使得稳压器内部汽相中的氢气不会通过稳压器安全阀泄漏出去,且由于集水罩设置在稳压器内部,节省了稳压器外部的布置空间,此外,由于采用了高温水密封,能有效降低稳压器安全阀开启后下游排放管线承受的水力载荷。
