style="font-size:16px;">水力控制閥的分類和工作原理根據(jù)給水系統(tǒng)中不同的設(shè)計(jì)要求和使用要求，還可以演變出十幾種用途的閥門(目前國外此類閥門已派生出近百種用途)。水力控制閥按用途可分為如下類型。水位控制閥。主要控制水池、水塔中的水位。減壓閥。將較高進(jìn)口壓力減小到某一需要的出口壓力，并依靠介質(zhì)自身的能量，使出口壓力自動(dòng)保持穩(wěn)定的閥門。水用安全閥（泄壓/持壓閥）。當(dāng)給水管路系統(tǒng)中的壓力超過設(shè)定壓力時(shí)，閥門自動(dòng)開啟泄壓，保護(hù)管線安全。止回閥。安裝在給水系統(tǒng)的水泵出口，防止介質(zhì)倒流，并消除水擊。電動(dòng)開關(guān)閥。以電磁閥作為先導(dǎo)閥，根據(jù)電信號(hào)，遙控開啟和關(guān)閉給水管路系統(tǒng)，可取代用來開啟和關(guān)閉的閘閥和蝶閥的大型電動(dòng)裝置，并可實(shí)現(xiàn)遠(yuǎn)程控制。流量控制閥。將過大的流量限制在一個(gè)預(yù)定值，并將上游的高壓減為所需要的下游低壓。壓差旁通平衡閥。用于空調(diào)系統(tǒng)供水管、回水管或集水器、分水器之間，控制供水管、回水管或集水器、分水器</span><span style="font-size:16px;">之間的壓差為設(shè)定值。緊急關(guān)閉閥。用于消防用水與生活用水并聯(lián)的供水系統(tǒng)中，自動(dòng)調(diào)配供水方向。</span> </p><p> <span style="font-size:16px;"> 水利控制閥就是水壓控制的閥門，水力控制閥由一個(gè)主閥及其附設(shè)的導(dǎo)管﹑導(dǎo)閥﹑針閥﹑球閥和壓力表等組成。根據(jù)使用目的﹑功能及場所的不同可演變成遙控浮球閥﹑減壓閥﹑緩閉止回閥﹑流量控制閥﹑泄壓閥﹑水力電動(dòng)控制閥、水泵控制閥等。減壓閥由主閥、導(dǎo)閥、針閥、球閥、微型過濾器和壓力表組成水力控制接管系統(tǒng)。使用時(shí)，當(dāng)調(diào)定出口壓力后，能自動(dòng)保持穩(wěn)定出口壓力。本產(chǎn)品利用導(dǎo)閥自力控制，不需要其它裝置和能源，保養(yǎng)簡便，壓力控制準(zhǔn)確度高，受進(jìn)口壓力和流量影響小，減壓穩(wěn)壓可靠。本系列閥門產(chǎn)品用于高層建筑、生活區(qū)等供水管網(wǎng)系統(tǒng)及城市供水工程。當(dāng)閥門從進(jìn)口端給水時(shí)，水流過針閥進(jìn)入主閥控制室，出口壓力通過導(dǎo)管作用到導(dǎo)閥上。當(dāng)出口壓力高于導(dǎo)閥彈簧設(shè)定值時(shí)，導(dǎo)閥關(guān)閉?？刂剖彝Ｖ古潘藭r(shí)主閥控制室內(nèi)壓力升高并關(guān)閉主閥，出口壓力不再升高。當(dāng)閥門出口壓力降到導(dǎo)閥彈簧設(shè)定壓力時(shí)，導(dǎo)閥開啟，控制室向下游排水。由于導(dǎo)閥系統(tǒng)排水量大于針閥的進(jìn)水量，主閥控制室壓力下降。進(jìn)口壓力使主閥開啟。在穩(wěn)定狀態(tài)下，控制室進(jìn)水、排水相同，主閥開度不變，出口壓力穩(wěn)定。</span>
