结构

J形橡胶密封圈是将密封圈做在阀座上的一种密封形式。密封圈由金属母材外包覆聚四氟乙烯及特种硫化橡胶层组成。金属芯使蝶板有足够的刚性，聚四氟乙烯的软硬过渡，以及橡胶层的弹性补偿确保阀门的可靠密封。

J shape rubber sealing ring is to do the sealing ring in one of the seat seal form. Cover ptfe sealing ring by metal material and special rubber layers. Metal core make the butterfly plate has enough rigidity,ptfe soft hard transition, and the elastic rubber layer sex compensation to ensure reliable sealing of the valve.

哑铃形橡胶密封圈是将密封圈做在阀座上的一种密封形式。哑铃形密封圈用O形橡胶紧固环限制，阻止密封圈滑出沟槽。该结构密封性能特别好，使用寿命长，但只限用于低压、常温的管路系统。密封圈更换容易，方便维修。

Dumbbell shape rubber sealing ring is to do the sealing ring in a seat seal form. Dumbbell ring with an o-ring rubber fastening ring, prevent seal slip out of the groove. Sealing performance is very good,this structure makes with long life, but will only be used for the pipeline system of low pressure and room temperature.The secret Sealing ring easy replacement,convenient maintenance.

扇形弹性橡胶密封圈是将密封圈做在蝶板上的一种密封形式。密封副的配合可用螺栓调节，当阀门经过一段时间的使用后，密封面有一定量的磨损，此时拧紧螺栓挤压扇形弹性橡胶密封圈，补偿磨损余量，延长阀门寿命。

The fan elastic rubber sealing ring is to do the sealing ring on the disc a sealing form. The matching of the sealing pair available bolt to adjust, When the valve after a period of time after use,sealing surface has a certain amount wear and tear,tightenboltsextrusionfanelasticrubbersealingring, To compensate the wear allowance,extend the life of the valve.

N形高弹性密封圈是将密封圈做在蝶板上的一种形式。N形高弹性密封圈用压板压住，并用螺栓固定，内部镶嵌金属钢丝索加强环，既有柔性又能防止密封圈径向胀缩。适合于中、高压管路系统。

N form high elastic sealing ring is to do the sealing ring on the disc a kind of form. N form high elastic sealing ring with press pressure,and screw bolt is fixed,the internal inlaid metal wire rope reinforcement ring, is both flexible and to prevent the sealing ring radial expansion. Suitable for medium and high pressure pipeline system.

密封圈镶在阀体上 The sealing ring is embedded in the valve body

密封圈没有预载和互不干涉，提供了一个长期的使用寿命和十分安全的可调节和更换性能；可在管线上直接更换密封圈 The sealing ring has no preload and does not interfere with each other, providing a long-term service life and very safe adjustable and replaceable performance; Sealing rings can be directly replaced on the pipeline

不会腐蚀的密封机构 Non corrosive sealing mechanism

采用EPDM密封圈，日照状况下最少二十年的抗老化性能可用于与更加苛刻的工况独特的环氧树脂静电喷涂使我们的蝶阀优于一般传统的阀门 With EPDM sealing ring, the anti-aging performance of at least 20 years under sunshine conditions can be used in more severe conditions. Unique epoxy resin electrostatic spraying makes our butterfly valve superior to conventional valves

密封机构：多重的表面波浪状密封3600正对球状阀体不锈钢密封圈，正因各波浪状的结构形式，使得橡胶的压缩力大大减少，从而降低了操作扭力。此种结构同样可以形成较大密封面，角度错位最大允许±1F而不会渗漏，蝶板沟槽采用特别多环氧树脂注入方法，从而使阀门密封圈上任意一点都达到相同的压力。它全可以由注入环氧树脂进行调节，它具备在线修复密封能力，使得免拆卸，减少工作量，但也很方便在使用场所更换密封圈。

Sealing ：mechanism?The multiple surface wavy seal 3600 is facing the valve body ball stainless steel sealing ring, because of the form of each wavy structure, the compression force of rubber is greatly reduced, thus reducing the operating torque. This structure can also form a large sealing surface, the maximum Angle dislocation allows ± 1F without leakage, the butterfly groove adopts a special polyepoxy resin injection method, so that any point on the valve sealing ring can reach the same pressure. It can be adjusted by injecting epoxy resin, it has the ability of online repair seal, making the disassembly free, reduce the workload, but it is also very convenient to replace the sealing ring in the place of use.
