產品介紹

ONE. Product introduction

全金屬焊接式硬密封蝶閥是我廠技術人員經優化設計，含國家的高性能雙向金屬硬密封蝶閥。采用了“斜置橢圓蝶板徑向動平衡密封系統”，可靠地實現了蝶閥進出口雙向密封零泄露，是真正具有水平的高科技新產品。該產品成批投產后，創造了良好的經濟效益和社會效益，并作為以國代進產品，被國內各企業大量選用深受廣大新老用戶的歡迎，是值得您高度信賴的優質產品。

     Welded butterfly valve is my factory technical personnel after the optimization design, seals the reed valve hardly including national monopoly's high performance bidirectional metal. Used “has tilted the ellipse butterfly board radial direction transient equilibrium full-pressure system”, has realized the reed valve import and export bidirectional seal zero revelation reliably, has the international advanced standard high tech new product truly. After this product goes into production in groups, has created the good economic efficiency and the social efficiency, and takes by the country takes into the product, is selected the depth massively by the domestic various enterprises general new old user's welcome, is quality product which is worth you trusting highly.

    焊接式全金屬硬密封蝶閥的蝶板在啟閉過程中，實現了蝶板密封圈與閥座密封面之間的無滑動磨擦.卡擠，密封面上的壓力角大于磨擦角，采用了“徑向動平衡密封系統”設計，使蝶板開啟阻力極低。啟閉過程中蝶板密封面沿360°圓周各點可以瞬間快速完成，逐點接觸和逐點脫離。開啟密封即分離，快速準確實現關閉接觸自動相吻合的密封動作。

     Welded butterfly valve's butterfly board in opens shuts in the process, has realized the butterfly board seal packing collar and between the valve seat packing surface non-glide friction. The card pushes, in the packing surface angle of pressure is bigger than the angle of friction, has used “the radial direction transient equilibrium full-pressure system” the design, causes the butterfly board opening resistance to be extremely low. Opens shuts in the process the butterfly board packing surface to be possible instantaneous to complete fast along 360°circumference each spot, contacts point by point and is separated from point by point. The opening seal is the separation, realizes the seal movement which accuray fast the closure contact automatic tallies.

     調節型多層次.全金屬硬密封蝶閥由于密封面采用多重密封和整體全金屬密封，經過高精度機械加工成橢圓形截面密封環，它與閥座金屬密封面組成密封副。這種密封結構，在高壓工況下產生塑性變形，在高溫或低溫工況下，不存在沖壓應力，焊接應力，彈性退活或咬壞脆裂現象。*解決了傳統蝶閥密封結構不合理引起泄漏的弊病，大大提高了閥門密封可靠性。

      Adjustment multi-level. The pure metal seals the reed valve hardly, because the packing surface uses the multiple seals and the overall pure metal seal, passes through the high accuracy machine-finishing ellipse section packing ring, it and valve seat metal packing surface composition seal. This kind of seal structure, has the plastic deformation under the high-pressured operating mode, under the high temperature either the low temperature operating mode, does not have the ramming stress, the welding stress, the elasticity draws back lives or nips the bad embrittlement phenomenon. The thorough settlement tradition reed valve seal structure has caused the divulging disease unreasonable, enhanced the valve seal reliability greatly.

     我們設計的整體全金屬密封型式在400℃-850℃超高溫工況下，在產生強力水刀的工況下，優點就異常突出，不變形，密封面不被切割，同樣保持良好的密封。

     We design the overall pure metal seal pattern under 400℃-850℃ the superhigh temperature operating mode, in has under the force Shui Dao operating mode, the merit exceptionally is prominent, does not distort, the packing surface is not cut, similarly maintains the good seal.

     經實驗測定調節型硬密封蝶閥開啟扭矩為傳統結構蝶閥的1/3左右，使用壽命是傳統硬蜜蜂蝶閥的5-8倍。

     Determines the adjustment hard seal reed valve opening torque after the experiment for about traditional structure reed valve's 1/3, the service life is traditional hard honeybee reed valve's 5-8 times.

適用范圍

TWO.. Applicable scope

全金屬焊接式硬密封蝶閥適用于高，中。低壓，高溫，低溫的管路中作閉路密封裝置，節流裝置和調節裝置。廣泛適用于石油，化工，冶金，礦山，電力，能源，交通，農田，水力，環保，建筑，醫藥，生物等行業。特別適用密封性質要求嚴格的工況，如煤氣管道上，也適用水，蒸氣，油品，空氣，塵氣，硝酸等腐蝕性介質。

Welded butterfly valve is suitable for high. The low pressure, the high temperature, in the low temperature pipeline makes the close up packing assembly, the throttling gear and the adjusting device. Widely is suitable for the petroleum, the chemical industry, the metallurgy, the mine, the electric power, the energy, the transportation, the farmland, the water power, the environmental protection, the construction, the medicine, professions and so on biology. Is suitable the seal nature request strict operating mode specially, like on gas piping, also the suitable water used, the vapor, the oil quality, the air, the dust was mad, nitric acid and so on corrosive medium.
    使用溫州-196℃-850℃，工作壓力PN0.6-10MPa或150-600磅級。本閥*可以取代笨重，價高的閘閥，截止閥，球閥，節流閥，并作為以國代進產品。

Uses Wenzhou - 196℃-850℃, working pressure PN0.6-10MPa or 150-600 pounds levels. This valve definiy may substitute unwieldy, the price high gate valve, the cut-off valve, the ball valve, the throttle valve, and takes by the country takes into the product.
