TESCOM泄壓閥(fa)在運行過程中(zhong)，如發生故(gu)障，出現控制(zhi)失(shi)靈(ling)，應先檢查管(guan)潞是(shi)(shi)否暢通。再檢查閻體(ti)控制(zhi)管(guan)路上的水過濾(lv)器是(shi)(shi)否堵塞、主閥(fa)與(yu)導閥(fa)薄膜是(shi)(shi)否破裂、以及主閥(fa)與(yu)導稠的密封墊是(shi)(shi)否損(sun)壞。
美(mei)國TESCOM泄壓閥(fa)特點：
螺紋(wen)下端填(tian)充(chong)可防止潤滑劑沖蝕(shi)(shi)、螺紋(wen)腐蝕(shi)(shi)和(he)過程污染，同時避免(mian)磨損。
可方便調(diao)整的(de)(de)填充(chong)能減(jian)少更換(huan)時(shi)(shi)的(de)(de)停(ting)工時(shi)(shi)間，延長(chang)閥門壽命。
金屬對金屬的閥(fa)座泄放閥(fa)塞無需(xu)斷開螺紋(wen)連(lian)接(jie)便可保(bao)證安全地(di)排放壓力。
安全后閥(fa)座可(ke)防止(zhi)閥(fa)桿噴出或操作時移動(dong)，并(bing)在*打(da)開的位置提(ti)供(gong)金屬間(jian)的二級閥(fa)桿密封。
ENC 涂層的 316 SS 可(ke)防止(zhi)閥桿螺紋(wen)磨損或(huo)凍結。
滾制閥桿(gan)和閥蓋螺紋可增加(jia)強度(du)。
在(zai)填(tian)充位置進行閥桿鏡面拋光(guang)可使操作平穩，填(tian)充壽命延長。
一(yi)件式(shi)手柄(bing)設計可避(bi)免因振動(dong)或(huo)維護(hu)丟失(shi)。
用(yong)于氣密關閉的(de)軟質或金屬閥座可現場(chang)更換，方(fang)便維(wei)護。
閥(fa)門壽命延長：損壞的(de)軟閥(fa)座可(ke)移除，保留金屬(shu)閥(fa)座閥(fa)門。
