产品介绍

ONE. Product introduction

    焊接式全金属硬密封蝶阀是我厂技术人员经优化设计，含国家的高性能双向金属硬密封蝶阀。采用了“斜置椭圆蝶板径向动平衡密封系统”，可靠地实现了蝶阀进出口双向密封零泄露，是真正具有水平的高科技新产品。该产品成批投产后，创造了良好的经济效益和社会效益，并作为以国代进产品，被国内各企业大量选用深受广大新老用户的欢迎，是值得您高度信赖的优质产品。

     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.

    焊接式全金属硬密封蝶阀的蝶板在启闭过程中，实现了蝶板密封圈与阀座密封面之间的无滑动磨擦.卡挤，密封面上的压力角大于磨擦角，采用了“径向动平衡密封系统”设计，使蝶板开启阻力极低。启闭过程中蝶板密封面沿360°圆周各点可以瞬间快速完成，逐点接触和逐点脱离。开启密封即分离，快速准确实现关闭接触自动相吻合的密封动作。

     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.

     调节型多层次.全金属硬密封蝶阀由于密封面采用多重密封和整体全金属密封，经过高精度机械加工成椭圆形截面密封环，它与阀座金属密封面组成密封副。这种密封结构，在高压工况下产生塑性变形，在高温或低温工况下，不存在冲压应力，焊接应力，弹性退活或咬坏脆裂现象。*解决了传统蝶阀密封结构不合理引起泄漏的弊病，大大提高了阀门密封可靠性。

      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.

     我们设计的整体全金属密封型式在400℃-850℃超高温工况下，在产生强力水刀的工况下，优点就异常突出，不变形，密封面不被切割，同样保持良好的密封。

     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.

     经实验测定调节型硬密封蝶阀开启扭矩为传统结构蝶阀的1/3左右，使用寿命是传统硬蜜蜂蝶阀的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.

适用范围

TWO.. Applicable scope

焊接式全金属硬密封蝶阀适用于高，中。低压，高温，低温的管路中作闭路密封装置，节流装置和调节装置。广泛适用于石油，化工，冶金，矿山，电力，能源，交通，农田，水力，环保，建筑，医药，生物等行业。特别适用密封性质要求严格的工况，如煤气管道上，也适用水，蒸气，油品，空气，尘气，硝酸等腐蚀性介质。

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.
    使用温州-196℃-850℃，工作压力PN0.6-10MPa或150-600磅级。本阀*可以取代笨重，价高的闸阀，截止阀，球阀，节流阀，并作为以国代进产品。

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.
