Structural features of wafer butterfly valve:

1、三向偏心的獨(dú)特設(shè)計(jì)使密封面之間無摩擦傳動(dòng)，延長(zhǎng)了閥門使用壽命；

1. The unique design of three-way eccentricity makes no friction transmission between sealing surfaces, extending the service life of the valve;

2、由扭矩產(chǎn)生彈性密封；

2. Elastic seal generated by torque;

3、巧妙的楔形設(shè)計(jì)使閥門有越關(guān)越緊的自動(dòng)密封功能，密封面之間具有補(bǔ)償性、零泄漏；

3. The ingenious wedge-shaped design makes the valve have the function of automatic sealing, and the sealing surfaces have compensation and zero leakage;

4、體積小、重量輕、操作輕巧、便于安裝；

4. Small size, light weight, light operation and easy installation;

5、可根據(jù)用戶要求配置氣動(dòng)、電動(dòng)裝置，滿足遙控和程控的需要；

5. Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control;

6、更換零件材質(zhì)可適用于各種介質(zhì)，并可進(jìn)行襯里防腐(襯F46、GXPP、PO等)；

6. The material of the replaced parts can be applied to various media, and the lining can be anticorrosive (lining F46, gxpp, Po, etc.);

7、連續(xù)結(jié)構(gòu)多樣化：對(duì)夾、法蘭、對(duì)焊；

7. Continuous structure diversification: butt clamp, flange, butt welding;

法蘭式硬密封蝶閥特點(diǎn)：

Features of flange type hard seal butterfly valve:

1、蝶板密封圈為軟硬層迭式金屬片，具有金屬硬密封和彈性密封的雙重優(yōu)點(diǎn)，無論在低溫和高溫的情況下，均具有優(yōu)良的密封性能；

1. The butterfly plate seal ring is a soft and hard laminated metal sheet, which has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance at both low and high temperatures;

2、采用三維偏心結(jié)構(gòu)，閥座與蝶板幾乎無摩擦，具有越關(guān)越緊的密封功能；

2. The three-dimensional eccentric structure is adopted, and the valve seat and butterfly plate have almost no friction, with the sealing function of tighter and tighter closing;

3、閥體密封面，采用堆焊不銹鋼、鈷基硬質(zhì)合金，密封面耐磨損，使用壽命長(zhǎng)；

3. The sealing surface of the valve body is overlaid with stainless steel and cobalt based cemented carbide. The sealing surface is wear-resistant and has a long service life;

4、結(jié)構(gòu)獨(dú)特，操作靈活、省力、方便、不受介質(zhì)壓力的高、低影響，密封性能可靠；

4. Unique structure, flexible operation, labor-saving, convenient, not affected by high and low medium pressure, reliable sealing performance;
