A46F先導(dǎo)式安全閥
A46F先導(dǎo)式安全閥用途: 先導(dǎo)式安全泄壓閥是一種新穎結(jié)構(gòu)的安全閥。主要用于石油天然氣、化工、電力、冶金和城市燃?xì)獾阮I(lǐng)域,是受壓設(shè)備、容器或管路上的超壓保護(hù)裝置。其主要優(yōu)點(diǎn)是變彈簧直接作用為導(dǎo)閥間接作用,提高了動(dòng)作的靈敏度,而且主閥采用套筒活塞式,雙重密封閥座結(jié)構(gòu),動(dòng)作精度高、重復(fù)性好、回座快、不泄漏、能帶高背壓排放、工作等命長(zhǎng)、工作穩(wěn)定可靠,它還可在線調(diào)校,反復(fù)啟跳排放后,仍然能自動(dòng)回座,關(guān)閉嚴(yán)密,操作維護(hù)方便。 A46F先導(dǎo)式安全閥主要零部件材料: NO. | 零件名稱 | Ax46Y/F 材料 | KAX46Y/F材料 | 1 | 閥體 | WCB | WCB | 2 | 閥瓣 | 2Cr13/2Cr13+PTFE | 1Cr18Ni9Ti/1Cr18Ni9Ti+PTFE | 3 | 導(dǎo)向套 | 1Cr18Ni9Ti | 1Cr18Ni9Ti | 4 | 彈簧 | 50CrVA | 50CrVA | 5 | O型圈 | 氟橡膠 | 氟橡膠 | 6 | 閥蓋 | 25 | 25 | 7 | 導(dǎo)閥 | 部件 | A46F先導(dǎo)式安全閥外形尺寸和連接尺寸:
