產(chǎn)品詳情PRODUCT DESCRIPTION
產(chǎn)品工作原理和用途:
A44Y、A48Y型帶扳手彈簧全啟式安全閥適用于工作溫度≤350℃的蒸汽、空氣等介質(zhì)的設(shè)備和管路上。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)。
產(chǎn)品結(jié)構(gòu)特點(diǎn):
1、帶扳手彈簧全啟式安全閥具有結(jié)構(gòu)簡單、密封性能好、開啟壓力準(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。
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。閥瓣密封面采用先進(jìn)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:通過調(diào)整調(diào)節(jié)螺母,調(diào)整彈簧壓縮量,使閥門能夠很方便、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),使閥門背壓降低。下調(diào)時(shí),使閥門背壓提高。
