球形止回閥以其密封性好、流阻極小等性能優(yōu)勢(shì)，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(dú)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(lèi)之一，現(xiàn)有的止回閥存在阻力大、能耗大的問(wèn)題。降低流阻系數(shù)是流體傳輸節(jié)能的重要途徑。常見(jiàn)的止回閥包括球形止回閥、對(duì)夾式止回閥等。這些止回閥的共同缺點(diǎn)是：在流體正向流動(dòng)、止回閥打開(kāi)時(shí)，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(duì)流體的流動(dòng)阻力較大，使出水壓力有所降低，因此浪費(fèi)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(dòng)來(lái)實(shí)現(xiàn)閥門(mén)的啟閉。當(dāng)水泵開(kāi)動(dòng)時(shí)，水在壓力的作用下沖開(kāi)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(kāi)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(dá)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(guò)程中對(duì)管道系統(tǒng)的破壞。帶孔的錐型體在閥門(mén)打開(kāi)時(shí)對(duì)鋼球起固定作用和消除膠球與錐型體接觸面積的壓強(qiáng)。浙江鼎力閥門(mén)是一家專(zhuān)門(mén)生產(chǎn)制造銷(xiāo)售止回閥的公司，主要有雙瓣旋啟式止回閥，耐腐蝕緩沖止回閥等。大慶止回閥價(jià)位</p><p
