三、進口美標蝶閥產品特點：

1、蝶閥具有結構簡單、體積小、重量輕、材料耗用省，安裝尺寸小，開關迅速、90°往復回轉，驅動力矩小等特點，用于截斷、接通、調節(jié)管路中的介質，具有良好的流體控制特性和關閉密封性能。

2、蝶閥可以運送泥漿，在管道口積存液體最少。 低壓下，可以實現(xiàn)良好的密封。調節(jié)性能好。

3、蝶板的流線形設計，使流體阻力損失小，可謂是一種節(jié)能型產品。

4、閥桿為通桿結構，經過調質處理，有良好的綜合力學性能和抗腐蝕性，抗擦傷性。蝶閥啟閉時閥桿只作旋轉運動而不作升降運行，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計，以免在閥桿與蝶板連接處意外斷裂時閥桿崩出。

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。

驅動形式有手動、蝸輪傳動、電動、氣動、液動、電液聯(lián)動等執(zhí)行機構，可實現(xiàn)遠距離控制和自動化操作。

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 regulate the medium in the pipeline, with good fluid control characteristics and closing sealing performance.

2. The butterfly valve can transport mud, with the least liquid accumulated at the pipe mouth. Under low pressure, good sealing can be achieved. Good regulation performance.

3. The streamlined design of butterfly plate makes the loss of fluid resistance small, which can be described as an energy-saving product.

4. The valve rod is a through rod structure. After tempering treatment, it has good comprehensive mechanical properties, corrosion resistance and scratch resistance. When the butterfly valve is opened and closed, the valve rod only rotates without lifting, the packing of the valve rod is not easy to be damaged, and the sealing is reliable. It is fixed with the taper pin of the butterfly plate, and the extension end is designed to prevent the valve rod from bursting out when the valve rod is accidentally broken at the connection of the valve rod and the butterfly plate.

5. The connection methods include flange connection, clamp connection, butt welding connection and lug clamp connection.

The driving mode includes manual, worm gear drive, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation.

四、進口美標蝶閥產品簡介：

德國《LOCKE》洛克進口美標蝶閥的性能已處于國內外先進水平、廣泛適用于低壓、中壓、高壓、鋼鐵治金、石油、化工、電力等工業(yè)管道上作截斷或調節(jié)介質流量用。該閥門采用三維偏心斜錐形閥座密封，蝶板密封采用新型金屬片與彈性材料層疊而成，嵌裝在蝶板上與閥座吻合。利用蝶板擺動壓緊密封，所以密封面摩擦阻力小，關閉時具有越關越緊功能，這樣密封性可靠，開啟確保密封面完全脫離接觸，保證了密封面不受損傷。該蝶閥結構特點排除了其他類型蝶閥開過位而不能密封的缺點，且在高曙下能正常使用，克服了其它類型閥門在高溫使用時因熱膨脹而容易泄漏的缺點。該蝶閥耕具使用介質要求，選用不同密封面材料，以保證密封面耐磨損、耐腐蝕、使用壽命長。

The performance of Locke butterfly valve imported from Germany is at the advanced level at home and abroad, and it is widely used for cutting off or regulating medium flow on industrial pipelines such as low pressure, medium pressure, high pressure, iron and steel metallurgy, petroleum, chemical industry, electric power, etc. The valve is sealed by three-dimensional eccentric inclined cone valve seat, and the butterfly plate seal is made of a new type of metal sheet laminated with elastic material, which is embedded on the butterfly plate and coincides with the valve seat. The butterfly plate is used to swing and compress the seal, so the friction resistance of the sealing surface is small, and it has the function of closing more and more tightly when closing, so the sealing performance is reliable, the opening ensures that the confidential cover is completely separated from the contact, and ensures that the sealing surface is not damaged. The structure features of the butterfly valve eliminate the disadvantages of other types of butterfly valves that can not be sealed due to over opening, and can be used normally in gaoshu, overcoming the disadvantages of other types of valves that are easy to leak due to thermal expansion when they are used at high temperature. The butterfly valve cultivator requires different sealing surface materials to ensure the sealing surface is wear-resistant, corrosion-resistant and long service life.
