進(jìn)口對(duì)夾球閥德國洛克品牌-產(chǎn)品列表

進(jìn)口對(duì)夾球閥結(jié)構(gòu)特點(diǎn)：

對(duì)夾式球閥具有結(jié)構(gòu)長(zhǎng)度短、重量輕、安裝方便、節(jié)省材料等顯著優(yōu)點(diǎn)，適用于安裝位置比較短的場(chǎng)合，維修方便，閥門設(shè)計(jì)易拆卸，在閥門一端有螺旋閥蓋，此閥蓋控制閥座與球芯密封及開關(guān)松緊度。

進(jìn)口對(duì)夾球閥工作原理：

（1）球閥不受安裝方向的，介質(zhì)的流向可以任意。流體阻力小，全通徑的球閥基本沒有流阻。

（2）球閥結(jié)構(gòu)簡(jiǎn)單，相對(duì)體積小，重量輕，安裝方便，便于維修。

（3）緊密可靠，它有兩個(gè)密封面，而且目前球閥的密封面材料廣泛使用各種塑料，密封性能好能實(shí)現(xiàn)完全密封，在真空系統(tǒng)中也廣泛使用。

Working principle of imported wafer ball valve:
(1) The ball valve is not affected by the installation direction, and the flow direction of the medium can be arbitrary. Small fluid resistance, full bore ball valve basically no flow resistance.
(2) The ball valve has the advantages of simple structure, small volume, light weight, convenient installation and maintenance.
(3) Tight and reliable, it has two sealing surfaces, and the sealing surface material of ball valve is widely used in various plastics, with good sealing performance, which can realize complete sealing, and is also widely used in vacuum system.

進(jìn)口對(duì)夾球閥產(chǎn)品簡(jiǎn)介：

德國洛克《DE LOCKE》進(jìn)口對(duì)夾球閥關(guān)閉件球體繞閥體中心線作旋轉(zhuǎn)來達(dá)到開啟、關(guān)閉的一種閥門，密封件嵌于不銹鋼閥座內(nèi)，金屬閥座尾端設(shè)有彈簧，當(dāng)密封面磨損或者燒毀時(shí)，在彈簧作用下推動(dòng)閥座與球體形成金屬密封。進(jìn)口對(duì)夾球閥具有獨(dú)特的自動(dòng)泄壓功能，當(dāng)閥門中腔介質(zhì)壓力超過彈簧預(yù)緊力，出口端閥座后退脫離球體，達(dá)到自動(dòng)泄壓效果，泄壓后閥座自動(dòng)復(fù)位，進(jìn)口對(duì)夾球閥適用于水、溶劑、酸和天然氣等一般工作介質(zhì)，而且還適用于工作條件惡劣的介質(zhì)，如氧氣、過氧化氫、甲烷和乙烯等，在各行業(yè)得到廣泛的應(yīng)用。

Brief introduction of imported wafer ball valve products:
The ball of the closing part of the double clip ball valve imported from German Locke rotates around the center line of the valve body to open and close the valve. The sealing part is embedded in the stainless steel seat, and a spring is set at the end of the metal seat. When the sealing surface is worn or burned, the spring will push the seat to form a metal seal with the ball. The imported wafer ball valve has a unique function of automatic pressure relief. When the medium pressure in the valve cavity exceeds the spring preload, the valve seat at the outlet end retreats away from the ball to achieve the effect of automatic pressure relief. After pressure relief, the valve seat automatically resets. The imported wafer ball valve is suitable for water, solvent, acid, natural gas and other general working media, but also for media with poor working conditions, such as oxygen and peroxide Hydrogen, methane and ethylene are widely used in various industries.
