　　API 609凸缘式和对夹式蝶阀Flange type and clamp type butterfly valve

　　进口高性能双偏心蝶阀产品详情 Productdetails

　　高性能双偏心蝶阀 采用一体式的S型弹性密封阀座结构，使用了RPTFE材料，弹性好，寿命长，可自动补偿温度和压力的变化，以及因长期开关使用而磨损的密封补偿；能达到双向密封无泄漏；采用活动嵌件结构，保养快捷方便，不必拆卸蝶板和阀杆，只要单面取下压盘，即可更换密封阀座和检修密封面 RETZ The high-performance double eccentric butterfly valve adoptsan integrated S-shaped elastic sealing seat structure, and uses RPTFE material,which has good elasticity and long service life. It can automaticallycompensate for temperature and pressure changes, as well as seal compensationfor wear caused by long-term switch use; It can achieve two-way sealing withoutleakage; The movable insert structure is adopted for quick and convenientmaintenance. It is not necessary to remove the butterfly plate and valve rod.As long as the pressure plate is removed on one side, the sealing valve seatcan be replaced and the sealing surface can be repaired.

　　阀座设计特点 Valve seat designfeatures

　　耐火结构 Fire resistantstructure

　　耐火型阀门按API607经过火烧试验 The fire resistant type valve is subjected to fire test accordingto API 607.

　　阀座类型Seat type

　　阀门关闭时蝶板使阀座稍稍变形，这一变形“激励”了阀座，阀座密封面的激励使它与蝶板的边缘保持持久的密封 When the valve is closed, the butterfly valve seat is slightlydeformed, the deformation of the "incentive" of the valve seat, thevalve seat sealing surface to keep it with the edge of the disc to maintain apermanent seal

　　PTFE、R-PTFE、防火阀座等。PTFE,R-PTFE,Fireproofseat,etc.

　　轴的固定可靠Reliable fixing ofshaft

　　轴的顶端有防吹出结构，在轴意外断裂时防止轴的上部移窜出压盖 The anti-blow-out structure is providedat the top of the shaft toprevent the shaft from running out of the gland in case of accidental breakingof the shaft.

　　当压盘侧受压时，压力被施加于唇缘的下方进一步加大了蝶板与阀座之间的密封力 When insert the lateral compression, pressure is applied to furtherintensify the lip edge below the sealing force between valve disc and valveseat

　　偏置轴和偏心蝶板设计 Design ofoffset shaft and eccentric butterfly plate

　　在开启和处于中间位置时阀座与蝶板不发生接触 Inopen and in the middle position - seat and disc not contact

　　在阀座上下部位无磨损点 The seatpart no wear points up and down

　　扭矩低，操作机构要求小 Low torque,small operator requirements

　　当压力施加于非压盘的一侧时，蝶板被 推向阀座。由于蝶板的轮廓呈球形，蝶板越向阀座推进，关闭就越紧密。唇缘与压盘底部的槽接触，限制了阀座的过量移动When the pressure is applied to the side of the non insert piece,the butterfly plate is pushed to the valve seat. Because the outline of thebutterfly plate is spherical, the butterfly plate to the seat forward, thecloser the close. The lip edge is in contact with the groove at the bottom ofthe insert, limiting the excessive movement of the valve seat
