電站高溫截止閥概述： </p> <p> 可根據(jù)不同的壓力,溫度,采用特殊的結(jié)構(gòu)和相應(yīng)的密封,試壓采用工作壓力的1.5倍試壓,確保閥門在工作壓力的狀態(tài)下不會(huì)發(fā)生泄漏,同時(shí)保證在相應(yīng)的溫度下,密封不會(huì)發(fā)生變形,不密封不嚴(yán)的現(xiàn)像。焊接式電站截止閥,是電力,電氣,機(jī)電、電控設(shè)備工程中應(yīng)用zui多的閥門之一,由于其安裝方便,制造合理,經(jīng)濟(jì)簡(jiǎn)單,所以大量使用在電力工程等管道中,本公司生產(chǎn)的J61H/Y型，外表美觀，密封性性能好

style="text-indent:25px">截止閥注脂過程中還存在壓力問題，在注脂操作時(shí)，注脂壓力有規(guī)律地呈峰谷變化。壓力過低，密封漏或失效，壓力過高，注脂口堵塞、密封內(nèi)脂類硬化或密封圈與閥球、閥板抱死。通常注脂壓力過低時(shí)，注入的潤(rùn)滑脂多流入閥腔底部，一般發(fā)生在小型閘閥。而注脂壓力過高，一方面檢查注脂嘴，如是脂孔阻塞判明情況進(jìn)行更換；另一方面是脂類硬化，要使用清洗液，反復(fù)軟化失效的密封脂，并注入新的潤(rùn)滑脂置換。此外，密封型號(hào)和密封材質(zhì)，也影響注脂壓力，不同的密封形式有不同的注脂壓力，一般情況硬密封注脂壓力要高于軟密封。電站焊接截止閥按介質(zhì)的流向分有直通式截止閥、直流式截止閥和角式截止閥。四川ＷＣ6美標(biāo)電站截止閥價(jià)格</p><p
