品牌：RETZ瑞茨/我們一直致力于流體控制和測控領(lǐng)域的持續(xù)創(chuàng)新，始于2005……
(二片式,三片式)進(jìn)口電動螺紋球閥依靠旋轉(zhuǎn)閥芯來使閥門暢通或閉塞。閥座采用彈性密封結(jié)構(gòu)，閥桿采用有倒密封的下裝式結(jié)構(gòu)，閥腔異常升壓時(shí)，閥桿不會被沖擊。retz The imported electric threaded ball valve (two piece, three piece) relies on a rotating valve to make the valve smooth or blocked. The valve seat adopts an elastic sealing structure, and the valve stem adopts a bottom mounted structure with an inverted seal. When the valve chamber is abnormally pressurized, the valve stem will not be impacted
進(jìn)口電動焊接球閥設(shè)計(jì)特色 Design features
開閉迅速，從全開到全關(guān)只要旋轉(zhuǎn)90°，便于遠(yuǎn)距離的控制Quick opening and closing, with only 90 ° rotation from full opening to full closing, facilitating remote control
在全開或全閉時(shí)，球體和閥座的密封面與介質(zhì)隔離，介質(zhì)通過時(shí)，不會引起閥門密封面的侵蝕When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface
旋轉(zhuǎn)刻度盤頂部旋鈕即可輕松完成電動執(zhí)行機(jī)構(gòu)與閥門連接后的電氣、機(jī)械位置校準(zhǔn)調(diào)試 Rotate the top knob of the dial to easily complete the electrical and mechanical position calibration and debugging of the electric actuator connected to the valve
