產(chǎn)品描述
GQ947Y電動軌道球閥的詳細(xì)資料：
GQ947Y電動軌道球閥是新型實用產(chǎn)品，具有旋轉(zhuǎn)球芯90度擺切斷的一種新型球閥。 國內(nèi)目前所用Q型球閥均是在給定預(yù)緊力下球芯與閥座摩擦進(jìn)行開與關(guān)，經(jīng)常導(dǎo)致密封面損壞，閥門泄漏和卡死現(xiàn)象，軌道球閥就是針對上述常見缺陷進(jìn)行更新設(shè)計使球芯旋轉(zhuǎn)90度再開關(guān)的新型球閥，該球閥能使密封面無摩擦結(jié)合，達(dá)到無泄漏的安全目的，并大大提高了閥門的使用壽命。 一、GQ947H軌道球閥結(jié)構(gòu)特點 傳統(tǒng)的球閥，無論是浮動式或固定式，球體與閥座始終接觸，開關(guān)扭矩大，密封面容易損傷，軌道球輪著啟閉時，球體先偏轉(zhuǎn)-δ角，然后轉(zhuǎn)動，開關(guān)全過程中球體與閥座脫離，故閥座不會被擦傷，并且啟閉扭矩小。二、GQ947H軌道球閥主要零件材料 零件 名稱材料閥體WCBZG1Cr5Mo18-8CrNi18-12CrNiMo閥蓋WCBZG1Cr5Mo18-8CrNi18-12CrNiMo閥桿2Cr1338CrMoA11Cr18Ni9Ti1Cr18NiMo2aTi球體WCB+HCr1Cr5Mo18-8CrNi18-12CrNiMo閥座PTFE/13Cr/CrNi SS+STELLITE螺柱B7/35CrMoA1Cr17Ni2螺母2H/452Cr13填料PTFE/增強(qiáng)柔性石墨三、GQ947型PN1.6MPa～2.5MPa主要連接尺寸及重量 公稱通經(jīng)DN1520253240506580100125150200250300350400450500600L1301501601802002302903103504004806007308509801100120012501450H1220230240260307360410483512543581617672723758791828870940H24504865255506106406406757107408209059559901050110012701450H34154555005355806056406757107408209059559901050110012701450H4370400440460480500550600650713760820875930962102012851625GQ947型PN4.0MPa 公稱通經(jīng)DN1520253240506580100125150200250300350400450500600L1301501601802002302903103504004806007308509801100120012501450H1230240260280320360436492527607649701750750790832875910980H24865255506106406406757107408209059559901050110012701450H34555005355806056406757107408209059559901050110012701450H4400440460480500550600650713777835890950980104013051650GQ947型PN4.0PMPa 公稱通經(jīng)DN1520253240506580100125150200250300350400500600L130150160180200230290310350400480600730850980110012501450H12402602803003293654505095416637257817908068218588981020H25255506106406406757107408209059559901050110012701450H35005355806056056206406857358509009201100125013401555H4440460480500550600650713777835890950980104013051650 |
