一、ZZYV自力式微壓調(diào)節(jié)閥簡介:
ZZYV自力式微壓調(diào)節(jié)閥屬于自力式壓力調(diào)節(jié)閥的系列;是一種不需要外加任何能源的自力式閥,依靠介質(zhì)自身能源控制的得閥門,介于自力式閥門系列中ZZYP和ZZYVP中間的自力式閥.主要用于控制閥前壓力小于0.2MPa的場合。
二、ZZYV微壓調(diào)節(jié)閥特點:
1、調(diào)節(jié)彈簧設(shè)計在薄膜執(zhí)行機構(gòu)上方,利于現(xiàn)場調(diào)試。
2、無填料,閥桿上、下活動是不存在摩擦,上密封可靠
3、執(zhí)行機構(gòu)敏感元件極為靈敏,極微小的壓力變化會被感測出來
4、閥體為四通形式,因而K、B型可通用一種閥體
5、平衡型結(jié)構(gòu),不受閥前壓力影響
三、ZZYV自力式微壓調(diào)節(jié)閥主要零件:
1 閥體
2 膜片
3 膜蓋
4 調(diào)節(jié)彈簧
5 平衡膜片
四、ZZYV自力式微壓調(diào)節(jié)閥原理:
該閥采用大膜片執(zhí)行機構(gòu)輸出力大穩(wěn)定,對壓力流量微小變化極其敏感,控制精度很高,閥芯采用單座流開(高進低出)設(shè)計,在閥蓋處(和閥體連接處)安裝有平衡膜片(起到閥前壓力平衡,消除不平衡力)閥后壓力經(jīng)取壓管進入薄膜執(zhí)行機構(gòu),同薄膜執(zhí)行機構(gòu)調(diào)節(jié)彈簧相比較,壓力達不到設(shè)定值(調(diào)節(jié)壓縮執(zhí)行機構(gòu)彈簧)閥后壓力則變大,反之則變小。
