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(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)。

A41Y不銹鋼安全閥的詳細(xì)資料:

 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:

 A41Y不銹鋼安全閥產(chǎn)品特點(diǎn)

  1. 全啟式結(jié)構(gòu),排量大
  2. 閥瓣處設(shè)有反沖盤部件
  3. 平面結(jié)構(gòu)的閥瓣和閥座易于維修和重新加工
  4. 整定壓力偏差小,可達(dá)±3%
  5. 選用優(yōu)質(zhì)的彈簧鋼,保證彈簧的壽命和穩(wěn)定性

 A41Y不銹鋼安全閥各種工況下使用壽命安全閥比較合理:
(l)熱水鍋爐一般用不封閉帶扳手微啟式安全閥。 
    (2)蒸汽鍋爐或蒸汽管道一般用不封閉帶扳手全啟式安全閥。
  (3)水等液體不可壓縮介質(zhì)一般用封閉微啟式安全閥,或用安全泄放閥。
 ?。?)高壓給水一般用封閉全啟式安全閥,如高壓給水加熱器、換熱器等。
 ?。?)氣體等可壓縮性介質(zhì)一般用封閉全啟式安全閥,如儲(chǔ)氣罐、氣體管道等。
 ?。?)E級(jí)蒸汽鍋爐一般用靜重式安全閥。
 ?。?)大口徑,大排量及高壓系統(tǒng)一般用脈沖式安全閥,如減溫減壓裝置、電站鍋爐等,如圖8所示。
 ?。?)運(yùn)送液化氣的火車槽車、汽車槽車、貯罐等一般用內(nèi)裝式安全閥,如圖4所示。
 ?。?)油罐頂部一般用液壓安全閥,需與呼吸閥配合使用。
 ?。?0)井下排水或天然氣管道一般用先導(dǎo)式安全閥,如圖6所示。
 ?。?1)液化石油氣站罐泵出口的液相回流管道上一般用安全回流閥。
 ?。?2)負(fù)壓或操作過(guò)程中可能會(huì)產(chǎn)生負(fù)壓的系統(tǒng)一般用真空負(fù)壓安全閥。
 ?。?3)背壓波動(dòng)較大和有毒易燃的容器或管路系統(tǒng)一般用波紋管安全閥。

訂貨須知:

一、①產(chǎn)品名稱與型號(hào)②口徑③是否帶附件以便我們的為您正確選型④使用壓力⑤使用介質(zhì)的溫度。
二、若已經(jīng)由設(shè)計(jì)單位選定公司的安全閥型號(hào),請(qǐng)型號(hào)直接向我司銷售部訂購(gòu)。

三、當(dāng)使用的場(chǎng)合非常重要或環(huán)境比較復(fù)雜時(shí),請(qǐng)您盡量提供設(shè)計(jì)圖紙和詳細(xì)參數(shù),由我們的閥門公司專家為您審核把關(guān)。如有疑問(wèn):請(qǐng):我們一定會(huì)盡心盡力為您提供優(yōu)質(zhì)的服務(wù)。提供zui全面、專業(yè)的“閥門系統(tǒng)解決方案”,也十分愿意幫助用戶解決生產(chǎn)中所遇到的難題。
