產(chǎn)品介紹
閥桿螺母
閥桿螺母的材料完全符合API標(biāo)準(zhǔn)，可耐高溫，抗腐蝕能力強(qiáng)。
螺栓連接
栓接閥桿的制造嚴(yán)格按照API600標(biāo)準(zhǔn)規(guī)范。螺母的制造嚴(yán)格按照ANSI B1.1標(biāo)準(zhǔn)規(guī)范。
栓接螺母,六角形, 剛性,熱鍛,制造嚴(yán)格按造標(biāo)準(zhǔn)ANSI B 18.2.2.
閥蓋
閥蓋和閥體壁厚相同與支架連接或分開.體蓋連接法蘭的孔口平面能與螺栓螺母完全吻合.
當(dāng)閥門全開時(shí)可以更換填料,閥桿填料函尺寸嚴(yán)格按照API標(biāo)準(zhǔn)執(zhí)行.
閥桿
單片結(jié)構(gòu)的閥桿表面經(jīng)過(guò)熱處理，硬度良好。頭部呈圓形且表面經(jīng)過(guò)拋光處理，可降低其與閥板接套之間的摩擦。
閥板
閥板可隨閥桿自由轉(zhuǎn)動(dòng)，當(dāng)關(guān)閉閥門時(shí)可減小與閥座之間的摩擦。閥板鍛造并經(jīng)過(guò)磨圓，鏡面拋光，熱處理和硬度調(diào)整。
閥體
鑄鋼閥體的壁厚高于API600的最低標(biāo)準(zhǔn)要求.通口和閥座尺寸按照ANSI B 16.5
的管件標(biāo)準(zhǔn)要求設(shè)計(jì)�？筛鼡Q閥座，體蓋連接為內(nèi)外螺紋副，閥體中心為橢圓形可增加中腔壁厚, 承壓力能力亦隨之增強(qiáng)。
Design
