進(jìn)口高性能蝶閥選德國(guó)洛克專(zhuān)業(yè)生產(chǎn)質(zhì)量放心   

一、進(jìn)口高性能蝶閥產(chǎn)品簡(jiǎn)介：

德國(guó)《LOCKE》洛克進(jìn)口高性能蝶閥采用雙偏心結(jié)構(gòu)設(shè)計(jì)。閥軸雙偏離閥體結(jié)構(gòu)中心，同時(shí)結(jié)合閥板圓弧密封面設(shè)計(jì)，使閥板在打開(kāi)時(shí)迅速脫離密封座，以減小密封面的摩擦力，閥板在關(guān)閉時(shí)具有良好的密封性能。中心自定位密封閥座結(jié)構(gòu)設(shè)計(jì)結(jié)合獨(dú) 特的閥座補(bǔ)償密封設(shè)計(jì)，使閥座密封得到有效補(bǔ)償?shù)耐瑫r(shí)減少開(kāi)啟、關(guān)閉時(shí)的摩擦力，大大減小閥門(mén)的操作力，有效提高了蝶閥的控制精確度。該系列蝶閥密封性能穩(wěn)定可靠，使用壽命長(zhǎng)。適用于一般腐蝕性氣體，液體介質(zhì)的調(diào)節(jié)和切斷使用。

The imported high-performance butterfly valve Locke from Germany adopts the double eccentric structure design. The valve shaft deviates from the structure center of the valve body. At the same time, combined with the design of the arc sealing surface of the valve plate, the valve plate is quickly separated from the sealing seat when it is opened, so as to reduce the friction of the sealing surface. The valve plate has good sealing performance when it is closed. The structure design of the center self positioning seal valve seat combined with the unique valve seat compensation seal design can effectively compensate the valve seat seal, reduce the friction during opening and closing, greatly reduce the operating force of the valve, and effectively improve the control accuracy of the butterfly valve. This series of butterfly valves have stable and reliable sealing performance and long service life. It is suitable for regulating and cutting off the general corrosive gas and liquid medium.

三、進(jìn)口高性能蝶閥產(chǎn)品優(yōu)點(diǎn)：

1、蝶閥為雙向承壓，雙向金屬密封，特殊的結(jié)構(gòu)形式可任意調(diào)整密封比壓，采用偏心S形錐形閥座密封面，使密封面不易損壞，提高閥門(mén)的使用壽命。

2、操作扭矩較小，轉(zhuǎn)90度啟閉，輕便迅速。

3、流阻小，具有良好的水力特性，流量特性近似傾斜直線 ，節(jié)能效果好，雙向密封對(duì)水流無(wú)方向要求。

4、密封可靠，啟閉壽命達(dá)數(shù)25000次以上。

1. The butterfly valve is of two-way pressure bearing and two-way metal sealing. The sealing pressure ratio can be adjusted arbitrarily in special structure. The eccentric S-shaped cone-shaped seat sealing surface is adopted, which makes the sealing surface not easy to be damaged and improves the service life of the valve.

2. Operating torque is small, turn 90 degrees open and close, light and fast.

3. It has small flow resistance, good hydraulic characteristics, flow characteristics similar to inclined straight line, good energy-saving effect, two-way sealing has no direction requirements for water flow.

4. The seal is reliable, and the opening and closing life is more than 25000 times.
