宜在波紋管減壓閥前加過濾器。在選用減壓閥時，應注意不得超過減壓閥的減壓范圍。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帶動閥瓣運動的減壓閥。這種形式結構簡單、耐用，但不精確。目前較少采用。⑵先導式先導式減壓閥是由主閥和導閥組成，出口壓力的變化通過導閥放大控制主閥動作的減壓閥。在此類閥中，導閥的作用是輔助控制主閥或者完全控制主閥。導閥本身可以是一個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構。而實質上。導閥工作的目的是以維持預定壓力下的流量的方法來調節(jié)主閥的開啟量。先導式減壓閥的壓力控制精度非常精確，且結構緊湊，對于功能相同的減壓閥來說，通常先導式比直接作用式結構小得多。在這種形式中，導閥和主閥可以是整體的，也可以是適用于遠距離壓力信號控制的單獨的裝置，它還能作遠距離開關控制，也就是由控制中心控制的成套系統(tǒng)中的部件。另外，通過安裝適當型式的導閥能夠獲得由溫度直接控制的設備。由于先導式減壓閥結構復雜，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濾器。</p><p>
