A41H-彈(dan)簧微啟(qi)封閉式(shì)安全閥(fá)
介(jiè)質的設(she)備或管(guan)路上，作(zuo)為超壓(ya)保護裝(zhuang)置。連接(jiē)法蘭标(biao)準按🤞jb/t……94/系(xì)列。
彈簧(huang)微啟封(feng)閉式安(an)全閥結(jié)構簡述(shù)
1、彈簧微(wēi)啟式安(ān)全閥具(jù)有結構(gou)簡單、密(mì)封性能(neng)好、開💃🏻啟(qǐ)壓力準(zhun)🌈确、排放(fàng)能力大(dà)、回座壓(ya)差小、調(diào)整方便(bian)等特點(dian)。
2、噴嘴型(xing)閥座：閥(fá)座為位(wèi)伐爾噴(pen)嘴型閥(fá)座，蒸汽(qì)流經閥(fá)座出💋口(kǒu)處時達(dá)到音速(su)，排放系(xi)數大，閥(fá)座密封(fēng)面堆焊(han)钴鉻鎢(wū)硬♍質合(he)金，耐磨(mó)抗沖蝕(shi)，壽命長(zhǎng)。
3、熱彈性(xìng)閥瓣：閥(fá)瓣設計(jì)為熱彈(dan)性結構(gou)，利用其(qi)在介質(zhì)⛱️壓力下(xia)👅微小的(de)變形，提(ti)高密封(feng)能力，克(kè)服安全(quan)閥✨在介(jie)質壓力(li)下㊙️臨近(jin)整定壓(yā)力時的(de)前洩現(xiàn)象。閥瓣(ban)密封面(mian)采用先(xian)✍️進的激(ji)光淬火(huo)技術，提(tí)高了硬(yìng)度、耐磨(mó)性、抗沖(chòng)抗性。
4、調(diào)節螺母(mǔ)：通過調(diào)整調節(jiē)螺母，調(diao)整彈簧(huang)壓縮量(liàng)，使閥門(men)能夠很(hen)方便、很(hěn)迅速地(dì)獲得準(zhǔn)确的整(zhěng)定壓力(lì)。
5、背壓調(diào)整套：調(diao)整閥瓣(ban)背壓的(de)輔助機(jī)構，通過(guo)背壓調(diao)🏒整🔅套🔞調(diào)整♈，可獲(huo)得合适(shi)的回座(zuo)壓差。上(shàng)調時，使(shǐ)閥門背(bei)壓降♉低(dī)。下調時(shi)，使閥門(mén)背壓提(ti)高。 彈簧(huáng)微啟封(feng)閉式安(ān)全閥安(an)裝說明(míng)
1、安全閥(fá)必須垂(chuí)直安裝(zhuāng)，并最好(hao)直接安(an)裝在容(rong)器或管(guan)道🏃♂️的接(jie)頭上。接(jiē)頭内徑(jing)應不小(xiao)于安全(quan)閥的進(jìn)口通徑(jìng)。
2、安全閥(fa)的出口(kǒu)必須裝(zhuang)設适當(dang)的膨脹(zhàng)節，以防(fáng)止排放(fàng)管的熱(re)膨😍脹給(gei)安全閥(fá)帶來不(bu)應有的(de)熱應力(li)。排放管(guǎn)☀️内徑🐉應(yīng)比閥門(men)出口直(zhi)徑大，長(zhǎng)度盡可(kě)能短，避(bi)免拐彎(wān)。排放管(guan)及膨脹(zhang)節重量(liàng)不應作(zuò)用在安(ān)全閥上(shàng)，應固定(ding)在建築(zhu)上。排放(fàng)管的中(zhōng)心線與(yǔ)閥體的(de)中心線(xian)間距離(lí)盡可能(neng)的短。對(duì)每台安(an)全閥都(dou)應單獨(du)🆚裝設排(pái)放管。
3、消(xiāo)聲器的(de)出口處(chu)要有足(zú)夠的面(mian)積，防止(zhi)産生背(bèi)壓影響(xiang)閥門的(de)排放能(néng)力。
