切斷和節(jié)流都能用,流體阻力小,操作省力。蝶閥,可以做成很大口徑。能夠使用蝶閥的地方,比較好不要使閘閥,因?yàn)榈y比閘閥經(jīng)濟(jì),而且調(diào)節(jié)性好。目前,蝶閥在熱水管路得到***的使用。4.球閥球閥的工作原理是靠旋轉(zhuǎn)閥戀來使閥門暢通或閉塞。球閥開關(guān)輕便,體積小,可以做成很大口徑,密封可靠,結(jié)構(gòu)簡單,維修方便,密封面與球面常在閉合狀態(tài),不易被介質(zhì)沖蝕,在各行業(yè)得到***的應(yīng)用。球閥分兩類,一是浮動(dòng)球式,二是固定球式。5.旋塞閥旋塞閥是依靠旋塞體繞閥體中心線旋轉(zhuǎn),以達(dá)到開啟與關(guān)閉的目的。它的作用是切斷、分田和改變介質(zhì)流向。結(jié)構(gòu)簡單,外形尺寸小,操作時(shí)只須旋轉(zhuǎn)90度,流體阻力也不大。其缺點(diǎn)是開關(guān)費(fèi)力,密封面容易磨損,高溫時(shí)容易卡住,不適宜于調(diào)節(jié)流量。旋塞閥,也叫旋塞、考克、轉(zhuǎn)心門。它的種類很多,有直通式、三通式和四通式。6.止回閥止回閥是依靠流體本身的力量自動(dòng)啟閉的閥門,它的作用是阻止介質(zhì)倒流。它的名稱很多,如逆止閥、單向閥、單流門等。按結(jié)構(gòu)可分兩類。(1)升降式:閥瓣沿著閥體垂直中心線移動(dòng)。這類止回閥有兩種:一種是臥式,裝于水平管道,閥體外形與截止閥相似,另一種是立式,裝于垂直管道,。(2)旋啟式:閥瓣圍繞座外的銷軸旋轉(zhuǎn),這類閥門有單瓣、雙瓣和多瓣之分。五河上五閥門推薦耐腐蝕：內(nèi)腔采用***環(huán)氧樹脂涂裝，防止腐蝕和生銹，不但可供生飲，而且可用污水系統(tǒng)。</p><div

3、電磁換向閥利用電磁鐵的通電吸合與斷電釋放而直接推動(dòng)閥芯來控制液流方向。它是電氣系統(tǒng)和液壓系統(tǒng)之間的信號轉(zhuǎn)換元件。電磁換向閥是利用電磁鐵吸力推動(dòng)閥芯來改變閥的工作位置。因?yàn)樗梢钥刂菩盘柊l(fā)送到一個(gè)按鈕開關(guān)，行程開關(guān)，限位開關(guān)，壓力繼電器，使用操作簡單，易于實(shí)現(xiàn)自動(dòng)化，所以***應(yīng)用。電磁換向閥的作用是它可以改變控制液流的方向，從而改變液動(dòng)換向閥的位置。由于操縱液動(dòng)換向閥的液壓推力可以很大，所以主閥可以做得很大，允許有較大的流量通過。這樣用較小的電磁鐵就能控制較大的液流。電磁換向閥工作原理是，通過電磁鐵控制滑閥閥芯的不同位置，以改變形油液的流動(dòng)方向。變換閥心在閥體內(nèi)的相對工作位置，使閥體各油口連通或斷開，從而控制液壓執(zhí)行元件（如液壓桿、液壓馬達(dá)）的換向或啟停。當(dāng)電磁鐵斷電時(shí)，滑閥由彈簧保持在中間位置或初始位置（脈沖式閥除外）。若推動(dòng)故障檢查按鈕可使滑閥閥芯移動(dòng)。4、其它閥門按閥的工作位置分類閥的工作位置稱為“位”，有幾個(gè)切換工作位置的閥就稱為“幾位”閥。經(jīng)常使用的有“二位”閥和“三位”閥。閥在未加控制信號或**作時(shí)所處的位置稱為零位。按閥的接口數(shù)目分類閥的接口（包括排氣口）稱為“通”。</p><p>
