進(jìn)口襯氟蝶閥工作原理：

（1）蝶閥具有結(jié)構(gòu)簡單、體積小、重量輕、材料耗用省，安裝尺寸小，開關(guān)迅速、90°往復(fù)回轉(zhuǎn)，驅(qū)動力矩小等特點(diǎn)，用于截?cái)唷⒔油?、調(diào)節(jié)管路中的介質(zhì)，具有良好的流體控制特性和關(guān)閉密封性能。

（2）蝶閥可以運(yùn)送泥漿，在管道口積存液體最少。 低壓下，可以實(shí)現(xiàn)良好的密封。 調(diào)節(jié)性能好。

（3）蝶板的流線形設(shè)計(jì)，使流體阻力損失小，可謂是一種節(jié)能型產(chǎn)品。

（4）閥桿為通桿結(jié)構(gòu)，經(jīng)過調(diào)質(zhì)處理，有良好的綜合力學(xué)性能和抗腐蝕性，抗擦傷性。蝶閥啟閉時(shí)閥桿只作旋轉(zhuǎn)運(yùn)動而不作升降運(yùn)行，閥桿的填料不易破壞，密封可靠。與蝶板錐銷固定，外伸端為防沖出型設(shè)計(jì)，以免在閥桿與蝶板連接處意外斷裂時(shí)閥桿崩出。

（5） 連接方式有法蘭連接、對夾連接、對焊連接及凸耳對夾連接。

（6）驅(qū)動形式有手動、蝸輪傳動、電動、 氣動、液動、電液聯(lián)動等執(zhí)行機(jī)構(gòu)，可實(shí)現(xiàn)遠(yuǎn)距離控制和自動化操作。

Working principle of imported fluorine lined butterfly valve:
(1) Butterfly valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, fast switch, 90 ° reciprocating rotation, small driving torque, etc. it is used to cut off, connect and adjust the medium in the pipeline, and has good fluid control characteristics and closing sealing performance.
(2) The butterfly valve can transport mud and store the least liquid at the pipe mouth. Under low pressure, good sealing can be achieved. Good regulation performance.
(3) The streamline design of the butterfly plate can reduce the loss of fluid resistance, so it is an energy-saving product.
(4) The valve stem is a through rod structure. After quenching and tempering, it has good comprehensive mechanical properties, corrosion resistance and scratch resistance. When the butterfly valve is opened and closed, the valve stem only rotates without lifting. The packing of the valve stem is not easy to be damaged and the seal is reliable. It is fixed with the taper pin of the butterfly plate, and the extended end is designed to prevent the valve stem from collapsing when the connection between the valve stem and the butterfly plate breaks accidentally.
(5) There are flange connection, clamp connection, butt welding connection and lug clamp connection.
(6) The driving forms include manual, worm gear drive, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation.
                                                                               

進(jìn)口襯氟蝶閥產(chǎn)品簡介：

德國洛克《DE LOCKE》進(jìn)口襯氟蝶閥采用對分兩片閥體組合，閥座與閥體內(nèi)襯一體化，閥門工作時(shí)，只有全塑閥座與襯塑蝶板與介質(zhì)接觸，產(chǎn)品可承受“除熔融堿金屬和元素氟”外的任何介質(zhì)腐蝕，閥桿與蝶板(鍛)為一體，表面均勻包覆一層FEP。閥體通道內(nèi)表面光滑，流體阻力小，CV值高，流通能力強(qiáng)，扭矩適中，采用四級密封結(jié)構(gòu)并在密封面外配以耐溫抗老化的SI橡膠的彈性襯墊閥座，完全達(dá)到介質(zhì)的零泄漏。

Introduction of imported fluorine lined butterfly valve products:
The imported fluorine lined butterfly valve "de Locke" from Germany adopts the combination of two-piece valve body. The valve seat and valve body lining are integrated. When the valve works, only the full plastic valve seat and the plastic lined butterfly plate are in contact with the medium. The product can withstand any medium corrosion except "molten alkali metal and element fluorine". The valve stem and butterfly plate (forged) are integrated, and the surface is evenly coated with a layer of FEP. The valve body has smooth inner surface, small fluid resistance, high CV value, strong circulation capability and moderate torque. It adopts four stage sealing structure and is equipped with the resilient cushion seat of the SI rubber with heat resistance and aging resistance outside the sealing surface, so as to achieve zero leakage of the medium completely.
