Q644F、Q645F氣動(dòng)三通球閥產(chǎn)品概述: Q644F、Q645F氣動(dòng)三通球閥可分為L(zhǎng)形氣動(dòng)三通球閥和T形氣動(dòng)三通球閥,L形(Q644F)三通球閥用于介質(zhì)流向的切換,能使相互垂直的兩個(gè)通道連接;T形(Q645F)三通球閥用于介質(zhì)分流、合流及流向切換。T形三通可以使三個(gè)通道相互連通或使其中的兩個(gè)通道連通。三通球閥一般采用兩閥座結(jié)構(gòu),亦可根據(jù)用戶要求采用四閥座結(jié)構(gòu)。
結(jié)構(gòu)特點(diǎn)
三通球閥在結(jié)構(gòu)上采用一體化結(jié)構(gòu),四面閥座的密封型式,法蘭聯(lián)接少,可靠性高,設(shè)計(jì)實(shí)現(xiàn)了輕量化。
