| 德國奧瑪品牌 進(jìn)口高溫高壓電站閘閥安裝在水,汽管道上作為啟閉裝置用。 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。可根據(jù)用戶要求選配揚(yáng)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(shí)，則采用半流體鋰基潤滑油(Q／sYl002—65) 用于管道溫度高于350~(：時(shí)，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:
1, high temperature high pressure power station gate valve with pressure from the tight-sealing structure, flexible gate, both ends of the manifold even welding.
Seat sealing surface cobalt-based alloy plasma spray welding made of wear-resistant, anti-abrasion performance.
Valve sealing surface hardening nitriding treatment.
3, stem surface nitriding process of corrosion resistance, good corrosion resistance and scratch resistance.
4, the high temperature high pressure station the gate valve opening and closing is controlled by the electric device, the electrical device equipped with dedicated motor, speed reducer, torque control means, live operating mechanism, the hand, the electric switch mechanism, except local operation can also be remote operation. A Series of the British ROTORK production can be introduced 2SA30 series introduce Siemens technology to produce according to the user requirements optional power equipment repair plant in Yangzhou, Shanghai Automation Instrumentation Co., Ltd. eleven plant Rickey monitoring and control equipment Limited the RA series production electric head.
