精小型氣動(dòng)薄膜套筒調(diào)節(jié)閥產(chǎn)品的概述：

ZXM（ZJHM）精小型氣動(dòng)薄膜套筒調(diào)節(jié)閥是-種壓力平衡式調(diào)節(jié)閥。配用多彈簧執(zhí)行機(jī)構(gòu)，總體結(jié)構(gòu)緊湊、重量輕、穩(wěn)定性好。流體通道呈S流線型、壓降損失小，允許壓差大，噪音小，流通能力大。廣泛應(yīng)用于精確控制氣體、液體等介質(zhì)工藝參數(shù)如壓力、流量、溫度、液位保持在給定值。特別適用于流量大，壓差大，泄漏量要求不高的場(chǎng)合。
本系列產(chǎn)品有標(biāo)準(zhǔn)型和調(diào)節(jié)切斷型、波紋管密封型、夾套保溫型等多種品種。產(chǎn)品公稱壓力等級(jí)有PN10、16、40、64，閥體口徑范圍由DN20～200，適用流體溫度由-200℃至+560℃，其范圍內(nèi)多種檔次。泄漏量標(biāo)準(zhǔn)有IV級(jí)或VI級(jí)。流量特性為線性或等百分比。多種品種、規(guī)格可供選擇。
精小型氣動(dòng)薄膜套筒調(diào)節(jié)閥產(chǎn)品的特點(diǎn)：

·采用平衡式閥芯結(jié)構(gòu)，軸向不平衡力小，允許壓差大，穩(wěn)定性好。
·套筒互換性強(qiáng)，拆裝方便，容易維修。
·全金屬閥芯結(jié)構(gòu)適用多種工作場(chǎng)合，達(dá)到IV級(jí)泄漏標(biāo)準(zhǔn)，ZXMQ型軟密封結(jié)構(gòu)閥芯達(dá)到VI級(jí)泄漏標(biāo)準(zhǔn)。
·閥體按流體力學(xué)原理設(shè)計(jì)成等截面低流阻流道，可調(diào)范圍大，固有可調(diào)比為50，額定流量系數(shù)增大30％。
·執(zhí)行機(jī)構(gòu)采用多彈簧結(jié)構(gòu)，高度減少30％。重量減輕30％。
·ZXMV型波紋管密封型調(diào)節(jié)閥，對(duì)移動(dòng)的閥桿形成了*的密封，堵絕流體外漏。
·ZXMJ型調(diào)節(jié)閥帶有保溫夾套，用于流體冷卻后易結(jié)晶、凝固造成堵塞的場(chǎng)合。

精小型氣動(dòng)薄膜套筒調(diào)節(jié)閥可選用的配件：

定位器（HEP定位器、韓國(guó)YT1000型）、空氣過(guò)濾減壓器、保位閥、行程開(kāi)關(guān)、閥位變送器、手輪機(jī)構(gòu)等
