彈簧微啟式安全閥一、簡介A47H彈簧微啟式安全閥本閥門適用于工作溫度≤350℃的蒸汽、空氣等介質(zhì)的設(shè)備或管路上。作為超壓保護(hù)裝置。二、結(jié)構(gòu)特點(diǎn)  1、彈簧微啟式安全閥具有結(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。三、零件材料零件名稱材料閥體WCB閥座ZG2Cr13調(diào)節(jié)圈ZG2Cr13閥瓣2Cr13導(dǎo)向套2Cr13閥蓋ZG230-450彈簧50CrVA閥桿2Cr13扳手ZG200-400調(diào)整螺桿45保護(hù)罩ZG200-400密封面材料"H"堆焊D507,"Y"堆焊Co基硬質(zhì)合金四、結(jié)構(gòu)圖彈簧微啟式安全閥結(jié)構(gòu)圖
