進(jìn)口焊接蝶閥結(jié)構(gòu)特點(diǎn)：

低流阻,流通性能好，具有雙向密封功能

獨(dú)特設(shè)計(jì)使密封面之間無(wú)摩擦傳動(dòng);

閥桿防吹出環(huán):防止閥桿在意外情況下被吹出

密封面之間具有補(bǔ)償性、零泄漏，有越關(guān)越緊的自動(dòng)密封功能

設(shè)計(jì)獨(dú)特的結(jié)構(gòu)，蝶板與閥座靠機(jī)械力進(jìn)行密封，而不依附于介質(zhì)壓力，它均可達(dá)到雙向密封

Structural features of imported welded butterfly valve:
Low flow resistance, good flow performance, with two-way sealing function
The unique design makes the sealing surface drive without friction;
Stem blow out ring: to prevent the stem from being blown out accidentally
There are compensative, zero leakage and automatic sealing function between sealing surfaces
The butterfly plate and valve seat are sealed by mechanical force, but not by medium pressure. It can achieve bidirectional sealing
                                                                               

進(jìn)口焊接蝶閥產(chǎn)品簡(jiǎn)介：

德國(guó)洛克《DE LOCKE》進(jìn)口焊接蝶閥采用精密的J形彈性密封圈和三偏心多層次金屬硬密封結(jié)構(gòu)，對(duì)焊式硬密封蝶閥被廣泛用于介質(zhì)溫度≤425℃的治金 、電力、石油化工、以及給排水和市政建設(shè)等工業(yè)管道上，作調(diào)節(jié)流量和載斷流體使用。該閥采用三偏心結(jié)構(gòu)，閥座與碟板密封面均采用不同硬度和不銹鋼制作，具有良好的耐腐蝕性，使用壽命長(zhǎng)，本閥有雙向密封功能。

Introduction of imported welded butterfly valve products:
The imported welding butterfly valve "de Locke" from Germany adopts precise J-shaped elastic sealing ring and three eccentric multi-layer metal hard sealing structure. The butt welding hard sealing butterfly valve is widely used in metallurgy, electric power, petrochemical industry, water supply and drainage, municipal construction and other industrial pipelines with medium temperature ≤ 425 ℃ to regulate flow and load off fluid. The valve adopts three eccentric structure, the valve seat and disc sealing surface are made of different hardness and stainless steel, with good corrosion resistance and long service life. The valve has two-way sealing function.
