style="font-size:16px;">力控制閥bai是以管道介質(zhì)壓力為動力，進(jìn)du行啟閉、調(diào)節(jié)zhi的閥門。它由一個主閥和附設(shè)的導(dǎo)管、針閥、球閥和壓力表等組成、根據(jù)使用的目的、功能場所的不同，可演變成遙控浮球閥、減壓閥、緩閉止回閥、流量控制器、泄壓閥、水力電動控制閥、緊急關(guān)閉閥等。導(dǎo)閥隨介質(zhì)的液位和壓力的變化[1]而動作，由于導(dǎo)閥種類很多，可以單獨使用或幾個組合使用，就可以使主閥獲得對水位和水壓及流量等進(jìn)行單獨和復(fù)合調(diào)節(jié)的功能。但主閥閥體類似截止閥，閥門全開時，其壓力損失比其他閥門要大得多，且各個開度損失系數(shù)越是與全閉狀態(tài)接近，越是劇增，閥門口徑越大就越。具有上述特性的閥門，在接近閥瓣的動作加速，易發(fā)生水錘的沖擊，接近全閉時，閥門動作越緩慢越好，于是可在閥瓣上設(shè)置節(jié)流裝置。另外先導(dǎo)閥的節(jié)流和動作部分要盡量避免設(shè)置特小口徑的孔口，以免堵塞。必要時要加過濾網(wǎng)，定期檢修及設(shè)置旁通管路。水力控制閥分隔膜型和活塞型兩類，工作原理相同，都是以上下游壓力差為動力，有導(dǎo)閥控制，使隔膜(活塞)液壓式差動操作，完全由水力自動調(diào)節(jié)，從而使主閥閥瓣完全開啟或完全關(guān)閉或處于調(diào)節(jié)狀態(tài)。</span> </p><p> <span style="font-size:16px;">水力控制閥就是用水bai壓控制的閥門，它由一個主du閥及其附設(shè)的導(dǎo)管、導(dǎo)閥、zhi針閥、球閥和壓力表等組成，這dao種裝置可制成遙控浮球閥、減壓閥、緩閉止回閥、流量控制閥、泄壓閥、水力電動控制閥等，因此它是各類閥中采用的控制方法而已，而減壓閥是用于系統(tǒng)減壓的，一般由可調(diào)式與比例式，按其減壓的方法有、重錘式、彈簧式、水力控制式(先導(dǎo)式)等；而泄壓閥則是當(dāng)系統(tǒng)壓力超過控制要求壓力時，把系統(tǒng)壓力采用泄排的方法進(jìn)行壓力控制，其也有水力控制式、彈簧式等。因此其作用不同，不能互用。水力控制閥是由一只主閥及其外裝之針形閥和先導(dǎo)閥等組合而成。水力控制閥是一系列多用處控制與平安類閥門的總稱。水力控制閥主要包括：1）遙控浮球閥；2)減壓穩(wěn)壓閥；3)緩閉式止回閥；4)泄壓閥；5)持壓閥等等。</span>
