style="text-indent:25px">定位器要保證表面光潔度，減少填料摩擦。無錫一體式閥門定位器生產(chǎn)廠</p><p style="text-indent:25px">定位器具體的作用包括以下這幾點(diǎn)。①定位器一般用于對(duì)調(diào)節(jié)質(zhì)量要求很高的調(diào)節(jié)系統(tǒng)中，主要是為了提高調(diào)節(jié)閥定位和可靠性。也就是說使用了定位器的調(diào)節(jié)閥的定位的精確度和可靠性會(huì)的提高。②如果閥門的兩端的差距比較大的話，可應(yīng)通過使用閥門調(diào)節(jié)器來調(diào)節(jié)。提高了氣源壓力增大執(zhí)行機(jī)構(gòu)的輸出力之后，可以減輕不平衡里，減少行程上產(chǎn)生的誤差。③被調(diào)節(jié)的介質(zhì)如果具備高溫、高壓、有毒、易爆等特性的話，一定要想辦法防止它外漏。一般為了防止外漏會(huì)采用將填料壓的很緊的做法，這樣會(huì)產(chǎn)生閥桿和填料之間產(chǎn)生很大的摩擦力，想要克服這種摩擦力就要使用定位器了。無錫一體式閥門定位器生產(chǎn)廠</p><p
