Y型快閉式止回閥（DYH41X）用于水泵出口處，在水泵停止時，起快速止回，防止水錘產(chǎn)生的作用。開泵時，閥瓣在水底推力下上升，開啟閥門，同時彈簧被簧力的作用下迅速關閉，當水流接近于0時，閥瓣完全關閉。無水倒流現(xiàn)象，同時因水不能倒流，不產(chǎn)生動能，便防止了水錘的產(chǎn)生。其特點：1.防止水錘的產(chǎn)生。2.關閉無聲音。3.水頭損失小。4.使用范圍廣。5.密封效果好。使用于清水、污水等系統(tǒng)中。二、主要技術性能： 1. Y型快閉式止回閥主閥體采用Y型膜片式結構，密封副為非金屬密封；閥門一般要求水平安裝，北京鑄鋼止回閥哪家強，與管道的連接形式為法蘭連接，法蘭連接尺寸按國家標準GB/T17241.6執(zhí)行。 2. Y型快閉式止回閥由閥體、閥蓋、中心軸，北京鑄鋼止回閥哪家強、銅套、閥座、閥瓣等主要零件組成，通過控制閥瓣的上下運動來實現(xiàn)閥門的啟閉。三、主要零部件材質：零件名稱材質閥體、閥蓋鑄鐵，北京鑄鋼止回閥哪家強、鑄鋼、不銹鋼閥桿鉻不銹鋼閥瓣碳鋼、不銹鋼+丁腈橡膠 O形圈丁腈橡膠彈簧不銹鋼導套黃銅、不銹鋼</p><div style="width:100%;text-align:

style="text-indent:25px">信號閘閥有哪些優(yōu)點？流體阻力小 , 密封面受介質的沖刷和侵蝕小。開閉較省力。介質流向不受限制 , 不擾流、不降低壓力。形體簡單 , 結構長度短，制造工藝性好，適用范圍廣。重量輕：本體采用高級球黑鑄鐵制成，重量較傳統(tǒng)閘閥重量減輕約20%~30%，安裝維修方便。平底式閘座：傳統(tǒng)的閘閥往往在通水洗管后即因外物諸如石頭，木塊、水泥、鐵屑、雜物等淤積于閥底凹槽內，容易造成無法關閉緊密而形成漏水現(xiàn)象，彈性座封閘閥底部采用與水管機同的平底設計，不易造成雜物淤積，使流體暢通無阻。信號閘閥缺點有哪密封面之間易引起沖蝕和擦傷，維修比較困難。外形尺寸較大，開啟需要一定的空間，開閉時間長。結構較復雜。閘閥的種類 ,按密封面配置可分為楔式閘板式閘閥和平行閘板式閘閥 , 楔式閘板式閘閥又可分為 : 單閘極式、雙閘板式和彈性閘板式；平行閘板式閘閥可分為單閘板式和雙閘板式。按閥桿的螺紋位置劃分，可分為明桿閘閥和暗桿閘閥兩種。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
