當(dāng)前位置：上海申弘閥門有限公司> 供求商機(jī)> A41Y-不銹鋼安全閥
A41Y不銹鋼安全閥產(chǎn)品用途
不銹鋼安全閥A41Y整體材質(zhì)選用優(yōu)質(zhì)不銹鋼鑄造而成,，采用全封閉閥蓋和閥帽結(jié)構(gòu)，安全閥開(kāi)啟排放時(shí),，介質(zhì)不會(huì)向外界泄漏,，而全部通過(guò)排泄管排掉，又可防止灰塵等雜質(zhì)進(jìn)入閥內(nèi),，適用于溫度不高于200°C的腐蝕性氣體和需要大排量的液體介質(zhì),。上海申弘閥門有限公司是國(guó)內(nèi)生產(chǎn)安全閥的主導(dǎo)廠，廠內(nèi)建有遠(yuǎn)東*的安全閥測(cè)試中心,，國(guó)產(chǎn)*臺(tái)安全閥就是我廠誕生的,，二十多年來(lái)，申弘牌安全閥的品種已發(fā)展到百余個(gè)系列,，千余個(gè)規(guī)格,，產(chǎn)品廣泛應(yīng)用于鍋爐、石化,、電站以及國(guó)防工業(yè),。并為國(guó)內(nèi)*座核電站秦山核電站研制成功了*批核級(jí)安全閥。
安全閥是受壓設(shè)備,、容器或管路上的*超壓保護(hù)裝置,。當(dāng)設(shè)備壓力升高達(dá)到預(yù)定值時(shí)，安全閥自動(dòng)開(kāi)啟,，繼而全量排放,，防止設(shè)備壓力繼續(xù)升高；當(dāng)壓力降低到規(guī)定值時(shí),，安全閥及時(shí)自動(dòng)關(guān)閉,。申弘牌安全閥是選用者為保護(hù)工程設(shè)備安全運(yùn)行的的，zui科學(xué)的明智選擇,。所謂安全閥廣義上講包括泄放閥，從管理規(guī)則上看,，直接安裝在蒸汽鍋爐或一類壓力容器上,，其必要條件是必須得到技術(shù)監(jiān)督部門認(rèn)可的閥門,，狹義上稱之為安全閥，其他一般稱之為泄放閥,。安全閥與泄放閥在結(jié)構(gòu)和性能上很相似,，二者都是在超過(guò)開(kāi)啟壓力時(shí)自動(dòng)排放內(nèi)部的介質(zhì)，以保證生產(chǎn)裝置的安全,。由干存在這種本質(zhì)上類似性,，人們?cè)谑褂脮r(shí)，往往將二者混同,，另外,，有些生產(chǎn)裝置在規(guī)則上也規(guī)定選用哪種均可。因此,，二者的不同之處往往被忽視,。從而也就出現(xiàn)了許多間題。如果要將二者作出比較明確的定義,，則可按照《ASME鍋爐及壓力容器規(guī)范》*篇中所闡述的定義來(lái)理解：
