氣動(dòng)三通球閥是閥門的一種,可分為L(zhǎng)型和T型。L型三通球閥用于介質(zhì)流向的切換,能使相互垂直的兩個(gè)通道連通(如流向圖L型)。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)。四閥座密封三通球閥具有造型美觀、結(jié)構(gòu)緊湊合理,它不僅可實(shí)現(xiàn)介質(zhì)流向的切換,也可使三個(gè)通道相互連通,同時(shí)也可關(guān)閉任一通道,使另外兩個(gè)通道連通,靈活控制管路中介質(zhì)的合流或分流。
注:參數(shù)僅供參考,或有不全。閥門可根據(jù)要求選用不同壓力、材質(zhì)、口徑。具體請(qǐng)來(lái)電聯(lián)系或在線咨詢。
