Copeland BVL系列內(nèi)襯節(jié)流閥和控制閥
美國Copeland BVL系列：內(nèi)襯節(jié)流閥和控制閥
一些高壓和/或研磨服務(wù)需要耐磨襯里來延長球閥的使用壽命并防止壓力容器的腐蝕。杜邦公司為二氧化鈦服務(wù)制造了二十多年前的*道閥門。這些閥門現(xiàn)在仍在使用，是我們?yōu)榭蛻籼峁┳灾鲃?chuàng)新解決方案的一個例子。
用于E.I.DuPont的二氧化鈦閥
內(nèi)襯嚴(yán)重的服務(wù)科普蘭球閥二氧化鈦顆?？梢允卿h利，堅硬，非常具有磨蝕性。工作溫度通常約為1200°F（650°C）。高速氣體推動這些顆粒，合金60需要滿足身體的腐蝕要求。谷輪提供定期閥門的襯墊，其控制閥門線由各種材料（包括陶瓷）制成，以防止磨損。納入內(nèi)膽后，這些閥門的使用壽命延長了600％以上。
Copeland襯里控制閥用于高速磨料
控制閥在高溫，高速，磨蝕，腐蝕和粉末/礦石運輸?shù)膼毫庸r下可能需要對閥壁進行額外保護，以防止由于湍流或顆粒撞擊而造成的磨損。陶瓷襯里，碳化物或其他材料可以提供更長使用壽命的需求。谷輪閥門采用重型超大型組件，可提高可靠性并防止意外停機。

Some high pressure and/or abrasive services require an abrasion resistant liner to extend the life of the ball valve and to prevent erosion of the pressure containing body. Copeland manufactured it's first line valves over 20 years ago for E. I. DuPont for titanium dioxide service. These valves are still in service today and are an example of the innovative solutions we pride ourselves in providing for our customers.
Titanium Dioxide particles can be sharp, hard and very abrasive. Service temperatures are normally approximay 1200 F (650 C). High velocity gas propels these particles and Alloy 60 is required to meet the corrosion demands of the body. Copeland provides liner for regular valves and its control valve line made of a variety materials including ceramic to prevent wear. Life of these valves after inclusion of the liner was extended by over 600%.
Control Valves in the severe service conditions of high temperature, high velocities, abrasives, corrosives and powder/ore transport may require additional protection to the walls of the valve to prevent wear due to turbulance or particle impingement. Liners of ceramics, carbides or other materials can provide an answer to a need for longer service life. Copeland valves utilize heavy duty, oversized components that increase reliability and prevent unplanned outages.
