詳細(xì)介紹
A44Y適用于工作溫度≤300℃的空氣、石油等介質(zhì)的設(shè)備或管路上，作為超壓保護(hù)裝置。連接法蘭標(biāo)準(zhǔn)PN＜6.4MPa按JB/T-94系列1。PN≥6.4MPa按JB/T-94系列2標(biāo)準(zhǔn)。
一、帶板手全啟式安全閥結(jié)構(gòu)簡(jiǎn)述：
1、封閉帶板手全啟式安全閥具有結(jié)構(gòu)簡(jiǎn)單、密封性能好、開(kāi)啟壓力準(zhǔn)確、排放能力大、回座壓差小、調(diào)整方便等特點(diǎn)。
2、噴嘴型閥座：閥座為位伐爾噴嘴型閥座，蒸汽流經(jīng)閥座出口處時(shí)達(dá)到音速，排放系數(shù)大，閥座密封面堆焊鈷鉻鎢硬質(zhì)合金，耐磨抗沖蝕，壽命長(zhǎng)。
3、熱彈性閥瓣：閥瓣設(shè)計(jì)為熱彈性結(jié)構(gòu)，利用其在介質(zhì)壓力下微小的變形，提高密封能力，克服安全閥在介質(zhì)壓力下臨近整定壓力時(shí)的前泄現(xiàn)象。閥瓣密封面采用*的激光淬火技術(shù)，提高了硬度、耐磨性、抗沖抗性。
4、調(diào)節(jié)螺母：通過(guò)調(diào)整調(diào)節(jié)螺母，調(diào)整彈簧壓縮量，使閥門(mén)能夠很方便、很迅速地獲得準(zhǔn)確的整定壓力。
5、背壓調(diào)整套：調(diào)整閥瓣背壓的輔助機(jī)構(gòu)，通過(guò)背壓調(diào)整套調(diào)整，可獲得合適的回座壓差。上調(diào)時(shí)，使閥門(mén)背壓降低。下調(diào)時(shí)，使閥門(mén)背壓提高。
二、封閉帶板手全啟式安全閥安裝說(shuō)明：
1、安全閥必須垂直安裝，并直接安裝在容器或管道的接頭上。接頭內(nèi)徑應(yīng)不小于安全閥的進(jìn)口通徑。
2、安全閥的出口必須裝設(shè)適當(dāng)?shù)呐蛎浌?jié)，以防止排放管的熱膨脹給安全閥帶來(lái)不應(yīng)有的熱應(yīng)力。排放管內(nèi)徑應(yīng)比閥門(mén)出口直徑大，長(zhǎng)度盡可能短，避免拐彎。排放管及膨脹節(jié)重量不應(yīng)作用在安全閥上，應(yīng)固定在建筑上。排放管的中心線與閥體的中心線間距離盡可能的短。對(duì)每臺(tái)安全閥都應(yīng)單獨(dú)裝設(shè)排放管。
3、消聲器的出口處要有足夠的面積，防止產(chǎn)生背壓影響閥門(mén)的排放能力。
