a種是早期采用的結(jié)構(gòu)，為了便于加工閥座上的密封槽，必須把閥座與閥殼設(shè)計(jì)成可拆卸的，這就在結(jié)構(gòu)上增加了一道真空密封。現(xiàn)在絕大多數(shù)閥門都采用閥板上帶密封圈的結(jié)構(gòu)。
    選擇真空閥門的密封結(jié)構(gòu)時(shí)應(yīng)注意以下幾點(diǎn)：a.盡可能減少閥板下高真空側(cè)的放氣因素，例如選用放氣率小的密封墊材料等.b.關(guān)閥后密封圈截面上有*大的壓縮變形.c.結(jié)構(gòu)力求簡(jiǎn)單;d.制造方便;e.密封元件便于拆卸和修理。派克電磁閥D1FVE02BCVFOA37
