更新時間：2019-06-22 產(chǎn)品型號：A41Y 描述：A41Y不銹鋼安全閥，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)，安全閥開啟排放時，介質(zhì)不會向外界泄漏，而全部通過排泄管排掉，又可防止灰塵等雜質(zhì)進(jìn)入閥內(nèi)。

詳細(xì)介紹

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)，安全閥開啟排放時，介質(zhì)不會向外界泄漏，而全部通過排泄管排掉，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*的安全閥測試中心，國產(chǎn)*臺安全閥就是我廠誕生的，二十多年來，申弘牌安全閥的品種已發(fā)展到百余個系列，千余個規(guī)格，產(chǎn)品廣泛應(yīng)用于鍋爐、石化、電站以及國防工業(yè)。并為國內(nèi)*座核電站秦山核電站研制成功了*批核級安全閥。

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，安全閥自動開啟，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，安全閥及時自動關(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，二者都是在超過開啟壓力時自動排放內(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，人們在使用時，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理解：
