結(jié)構(gòu)簡述:

1、高溫高壓電站閘閥采用壓力自緊式密封結(jié)構(gòu)，彈性閘板，兩端支管為焊接連。
2、閥座密封面采用鈷基硬質(zhì)合金等離子噴焊而成，耐磨、抗擦傷性能好。
閥瓣密封面經(jīng)硬化氮化處理。
3、閥桿表面經(jīng)抗蝕性氮化處理，有良好的抗腐蝕和抗擦傷性。
4、高溫高壓電站閘閥的開啟和關(guān)閉由電動裝置來控制，電動裝置分別配有專用電機(jī)，減速器、轉(zhuǎn)矩控制機(jī)構(gòu)、現(xiàn)場操作機(jī)構(gòu)、手,電動切換機(jī)構(gòu)，除就地操作外還可進(jìn)行遠(yuǎn)距離操作?？筛鶕?jù)用戶要求選配揚州電力設(shè)備修造廠引進(jìn)西門子技術(shù)生產(chǎn)的2SA30系列、上海自動化儀表股份有限公司十一廠引進(jìn)英國ROTORK生產(chǎn)的A系列、瑞基測控設(shè)備有限公司生產(chǎn)的RA系列電動頭。

安裝說明:

1、電動閘閥必須垂直安裝，閥桿向上，介質(zhì)流向可從任何一側(cè)流入。
2、電動裝置安裝在環(huán)境溫度為一20"C～+40℃，相對濕度≤80％無腐蝕，無****性氣體環(huán)境中。
3、電動裝置用于管道溫度低于350"(：時，則采用半流體鋰基潤滑油(Q／sYl002—65) 用于管道溫度高于350~(：時，則采用DIN492—2N一4鈉基潤滑脂進(jìn)行潤滑。

Germany Omar brands imported as a lifting device with high temperature and high pressure power station gate valves installed on water, steam pipes.
Structure outlined:
