宜在波紋管減壓閥前加過(guò)濾器。在選用減壓閥時(shí)，應(yīng)注意不得超過(guò)減壓閥的減壓范圍。并保證在合理情況下使用。杠桿式減壓閥是采用重物或重力杠桿作敏感元件來(lái)帶動(dòng)閥瓣運(yùn)動(dòng)的減壓閥。這種形式結(jié)構(gòu)簡(jiǎn)單、耐用，但不精確。目前較少采用。⑵先導(dǎo)式先導(dǎo)式減壓閥是由主閥和導(dǎo)閥組成，出口壓力的變化通過(guò)導(dǎo)閥放大控制主閥動(dòng)作的減壓閥。在此類閥中，導(dǎo)閥的作用是輔助控制主閥或者完全控制主閥。導(dǎo)閥本身可以是一個(gè)小型的直接作用式減壓閥。此類閥門精確的控制方式取決于它的特定結(jié)構(gòu)。而實(shí)質(zhì)上。導(dǎo)閥工作的目的是以維持預(yù)定壓力下的流量的方法來(lái)調(diào)節(jié)主閥的開啟量。先導(dǎo)式減壓閥的壓力控制精度非常精確，且結(jié)構(gòu)緊湊，對(duì)于功能相同的減壓閥來(lái)說(shuō)，通常先導(dǎo)式比直接作用式結(jié)構(gòu)小得多。在這種形式中，導(dǎo)閥和主閥可以是整體的，也可以是適用于遠(yuǎn)距離壓力信號(hào)控制的單獨(dú)的裝置，它還能作遠(yuǎn)距離開關(guān)控制，也就是由控制中心控制的成套系統(tǒng)中的部件。另外，通過(guò)安裝適當(dāng)型式的導(dǎo)閥能夠獲得由溫度直接控制的設(shè)備。由于先導(dǎo)式減壓閥結(jié)構(gòu)復(fù)雜，因此需要經(jīng)常保養(yǎng)及清潔的工作條件。清潔工作條件常在閥入口處裝過(guò)濾器。烏魯木齊專業(yè)閥門報(bào)價(jià)烏魯木齊調(diào)節(jié)閥生產(chǎn)廠家。</p><div
