美標(biāo)鑄鋼截止閥1
【簡單介紹】
【詳細(xì)說明】
⊙閥桿設(shè)計(jì)
采用整體鍛造工藝制成,按照標(biāo)準(zhǔn)要求確定zui小直徑。
⊙彈簧加載填料沖擊系統(tǒng)
如果客戶要求,可采用彈簧加載填料沖擊系統(tǒng)提高填料密封的持久性和可靠性
⊙上密封座設(shè)計(jì)
我 公司提供的所有截止閥都有倒密封設(shè)計(jì),通常情況下,碳鋼截止閥的閥座設(shè)計(jì)采用分離式倒密封結(jié)構(gòu),不銹鋼截止閥的倒密封是直接加工或者是焊后加工。當(dāng)閥門在 全開位置時(shí),倒密封的密封面非??煽俊km然按照標(biāo)準(zhǔn) API 600中有倒密封,但這不作為在帶壓情況下更換填料的依據(jù)
⊙閥座
碳 鋼截止閥閥座通常采用鍛鋼材料,閥座密封面可根據(jù)客戶要求噴焊硬質(zhì)合金,NPS ≤ 10"的截止閥采用分離式螺紋旋入式閥座,如果用戶需要焊閥座結(jié)構(gòu)也可提供;NPS ≥12"截止閥采用焊閥座結(jié)構(gòu);不銹鋼截止閥的閥座一般采用整體式或者在本體上焊硬質(zhì)合金后直接加工閥座。如果用戶有需求,不銹鋼截止閥閥座也可采用分離 式螺紋旋入式和焊接閥座結(jié)構(gòu)
⊙閥桿螺母
通常情況下,閥桿螺母材料采用銅合金,同時(shí)可以根據(jù)用戶要求采用ASTM A439 D2等材料,對于大口徑的截止閥,裝滾動軸承,可以有效減小截止閥的開啟力矩使閥門可以輕松開關(guān)。
⊙特殊截止閥
除通用截止閥外,還可以提供低溫截止閥、波紋管截止閥和夾套截止閥等等
⊙采用標(biāo)準(zhǔn)Standards
