產品及特點/Products and features
1、 本閥采用雙偏心結構，具有越關越緊的密封功能，密封性能可靠。
2、 密封面材料選用不銹鋼和丁腈耐油橡膠配對，使用壽命長。
3、 橡膠密封圈即可位于閥體上，也可以位于蝶板上，可適用不同特點的介質，供用戶選擇。
4、 蝶板采用框架結構，強度高，過流面積大，流阻小。
5、 整體烤漆、能有效地防止銹蝕且只要更換密封閥座封閥材料，就可使用于不同介質。
6、 本閥具有雙向密封功能，安裝時不受介質流向的控制，也不受空間位置的影響，可在任何方向安裝。
7、 本閥結構獨特，操作靈活，省力，方便。
1, the double-valve eccentric structure, with the Commissioner of the tight seal function, sealed and reliable performance.
2, Deputy sealed material selection and nail stainless steel oil nitrile rubber match, long service life.
3, rubber seals to the valve body, can also board in the butterfly, the applicable characteristics of different media for users to choose.
4, a butterfly-frame structure, high strength, the flow of large, small flow resistance.
5, paint a whole, can effectively prevent corrosion and replace the seal as long as the closure valve seat materials can be used in different media
6, with two-way closed the valve function, from media at the time of installation of the flow of control, even without the impact of space location can beinstalled in any direction.
7, this valve unique structure, operational flexibility, saving and convenient.
釆用標準/Adoption standard
J形橡膠密封圈是將密封圈做在閥座上的一種密封形式。密封圈 由金屬材料外包覆取四氟乙烯及特種硫化橡膠層組成。金屬芯使蝶板 有足夠的剛性，聚四氟乙烯的軟硬過渡，以及橡膠層的彈性補償確保 閥門的可靠密封。
J-ring rubber seal will be done on the valve seat in a sealed form. Ring from the base metal, coated metal from ethylene and tetrafluoroethylene special vulcanized rubber layer. Tip of metal-core board so that there is sufficient rigidity, the soft and hard transition PTFE, rubber suction to the flexibility of compensation to ensure that a reliable valve seal.
啞鈴形橡膠密封圈是將密封圈做在閥座上的一種密封形式。啞鈴形密封圈用O形橡膠固環限制，阻止密封圈滑出溝槽。該結構密封性 能特別好，使用壽命長，但只限用于低壓，常溫的管路系統。密封圈 更換容易，方便維修。
Dumbbell-shaped rubber ring is to do in the ring on the valve seat form a seal. Dumbbell-shaped seal with O-ring rubberrestri-cted, to prevent ring slid off the trench. The structure of sealing performance particularly good, long life, but only for low-voltage, the normal temperature of the pipeline system. Seal replacement easy, easy maintenance.
扇形彈性橡膠密封圈是將密封圈做在蝶板上的一種密封形式。密 封面的配合可用螺栓調節，當閥座經過一段時間的使用后，密封面有 一定量的磨損，此時擰緊螺栓擠壓扇形彈性橡膠密封圈，補償磨損余 量，延長閥門壽命。
Fan-shaped flexible rubber ring is to do in the ring butterfly board form a seal. Seal can be used with bolts of the regulation, when the valve seat after a period of use, the sealing surface is a certain amount of wear and tear, then tighten bolts squeeze fan flexible rubber ring, compensation wear cushion to extend valve life.
N形高彈性密封圈是將密封圈做在蝶板上的一種形式。n形高彈性 密封用壓板壓住，并用螺栓固定，內部鑲嵌金屬鋼絲索加強環，既有 柔性又能防止密封圈徑向脹縮。適合于中、高壓管路系統。
N-Seal is a flexible ring will be done in the form of a butterfly board, n-shaped seal with a flexible clips and fixed with bolts, steel metal embedded within the Central Sisuo strengthen both flexible ring can prevent the radial expansion and contraction. Suitable for, high-pressure pipeline system.
