球形止回閥以其密封性好、流阻極小等性能優(yōu)勢，得到了范圍廣的應(yīng)用和推廣，其結(jié)構(gòu)從優(yōu)初的“單球式”止回閥逐步完善到“獨自多流道多球式”止回閥。止回閥是流體傳輸優(yōu)常用的設(shè)備種類之一，現(xiàn)有的止回閥存在阻力大、能耗大的問題。降低流阻系數(shù)是流體傳輸節(jié)能的重要途徑。常見的止回閥包括球形止回閥、對夾式止回閥等。這些止回閥的共同缺點是：在流體正向流動、止回閥打開時，止回閥的某些零部件例如閥瓣或球體等處于流道的**，存在一定的擋水面積，對流體的流動阻力較大，使出水壓力有所降低，因此浪費能量。球形止回閥結(jié)構(gòu)和工作原理編輯球形止回閥是一種采用多球、多流道、多錐型倒流體結(jié)構(gòu)的止回閥，主要由前后閥體、膠球、錐型體等組成。其工作原理是：膠球在球罩內(nèi)作短行程滾動來實現(xiàn)閥門的啟閉。當(dāng)水泵開動時，水在壓力的作用下沖開膠球，使膠球滾至右側(cè)，由后閥體中的錐形體固定其位置，止回閥開啟；泵停后，由于管路系統(tǒng)中的回水壓力，迫使膠球滾至左側(cè)前閥體，達到止回閻的關(guān)閉。膠球采用空心鋼球，外附彈性很好的橡膠既保證密封，又能保證減小關(guān)閥過程中對管道系統(tǒng)的破壞。帶孔的錐型體在閥門打開時對鋼球起固定作用和消除膠球與錐型體接觸面積的壓強。</p><p>
