style="text-indent:25px">氣動(dòng)高真空擋板閥是一款適用的工作介質(zhì)為空氣及非腐蝕性氣性的擋板閥。GDQ-J系列氣動(dòng)高真擋板閥在真空系統(tǒng)中作切斷或接通氣流之用。該閥以壓縮空氣為動(dòng)力，通過(guò)控制氣動(dòng)元件來(lái)改變氣路方向，執(zhí)行的氣缸驅(qū)動(dòng)使擋板閥做啟閉運(yùn)動(dòng)。隨著我國(guó)經(jīng)濟(jì)的發(fā)展，各個(gè)企業(yè)之間的競(jìng)爭(zhēng)也慢慢的加劇，特別是一些同行業(yè)的。比如說(shuō)電動(dòng)閥門(mén)行業(yè)，該產(chǎn)業(yè)主要是以中小型企業(yè)為主，其中不乏一些大企業(yè)做**，于是乎，就出現(xiàn)了人家生產(chǎn)什么，他們就生產(chǎn)什么。有的電動(dòng)閥門(mén)企業(yè)甚至打價(jià)格戰(zhàn)，故意拉低價(jià)格讓整個(gè)行業(yè)的利潤(rùn)下降，行為非常惡劣。當(dāng)然我國(guó)電動(dòng)閥門(mén)競(jìng)爭(zhēng)激烈，品質(zhì)較差是有多方面的原因的，這其中產(chǎn)量過(guò)剩是很大的一個(gè)原因。真空閥門(mén)行業(yè)一般是屬于勞動(dòng)密集型行業(yè)，針對(duì)于這點(diǎn)，一些閥門(mén)企業(yè)務(wù)必要轉(zhuǎn)向技術(shù)密集行業(yè)，這有這樣才有提高的空間，才能穩(wěn)定的發(fā)展。真空閥門(mén)歸于現(xiàn)場(chǎng)儀表，要求環(huán)境溫度應(yīng)在-25～60℃范圍，相對(duì)濕度≤95%。</p><div
