水泵**擴(kuò)散器使用技巧水泵擴(kuò)散器的濾網(wǎng)可以根據(jù)客戶的不同要求來制作，濾網(wǎng)的精度可由20目-200目選擇。水泵擴(kuò)散器在出口端設(shè)有矯直器，能消除管路中的渦旋，矯正流體流向。水泵擴(kuò)散器很容易拆卸濾網(wǎng)進(jìn)行清洗，在殼體留有排污口，可以快速排出腔內(nèi)污垢GI70-29水泵擴(kuò)散器不**是過濾外界的雜質(zhì)，它還能替代彎頭、過濾器以及泵吸入端的直管，從而降低了安裝成本。水泵擴(kuò)散器的出、入口端法蘭規(guī)格可以是出口端法蘭規(guī)格小于入口端，因此可以取代異徑彎頭。大的開通面積以及排放口使GI70-29水泵擴(kuò)散器很少需要維修，容易排水和沖洗。快速開啟旋鈕可以節(jié)省打開閥蓋的時(shí)間。閥體和閥蓋之間采用O型環(huán)實(shí)現(xiàn)密封，而不是常規(guī)的平墊片，由此可以避免以后每次維修時(shí)更換墊片。水泵擴(kuò)散器出口端的矯直葉片可以減小介質(zhì)的紊亂，從而減少介質(zhì)對(duì)泵的壓力和侵蝕，因此，水泵擴(kuò)散器也可以替代常規(guī)情況下為了消除介質(zhì)紊亂而需要的直管，從而節(jié)省了空間，時(shí)間以及成本。上海富樂閥門管件有限公司給您分享關(guān)于閥門信息，歡迎致電我司。北京不銹鋼閥門</p><p
