盤閥
Disc Valve
盤閥是通過(guò)滑動(dòng)圓盤來(lái)實(shí)現(xiàn)開(kāi)關(guān)的一種快開(kāi)快關(guān)型閥門。 其設(shè)計(jì)專門針對(duì)帶有磨損、 沖蝕特性的物料， 它能在惡劣工況下連續(xù)長(zhǎng)期的正常工作。
A disc valve is a quick-opening and quick-closing type of valve that operates by sliding a fi xed disc to control the fl ow. Its design and door are aimed at the materials with wearing and eroding characteristics, and it can work continuously and normally for a long time under harsh working conditions.
它獨(dú)有的硬密封面具有 自 研磨作用，使其在磨損、沖蝕物料上應(yīng)用的過(guò)程中不斷提高密封性，壽命要 比其他閥門長(zhǎng)好幾倍。
Its unique hard sealing surface has the function of self-abrasion, making it continuously improve the sealing performance in the process of application on wearing and eroding materials, and its service life is several times longer than other related valves.

特殊設(shè)計(jì) Special Design
閥桿密封的設(shè)計(jì)
閥桿和閥體的密封分高溫 G 型和低溫 P 型兩種，<200℃時(shí)使用 V 型 PTFE 環(huán)作為閥桿的填料，V 型 PTFE 可以減少較大溫差變化造成的外漏；≥200℃時(shí)使用石墨環(huán)和高碳盤根作為閥桿的填料并配以碟簧承載，以保證長(zhǎng)期密封。
Design of Valve Stem Seal
The sealing between valve stem and valve body comes in two types: high-temperature G-type and low-temperature P-type. If the temperature is <200 ° C, V-type PTFE rings are used as the stem packing to reduce the external leakage caused by signifi cant temperature diff erences. If the temperature is ≥200° C, graphite rings and high-carbon stem packing are used, along with disc springs for support, to ensure the long-term sealing.

應(yīng)用 Application
盤閥可在眾多的行業(yè)中得到廣泛的應(yīng)用，如治煉、采礦、電廠，煤氣化、煤 液化、玻璃、陶瓷、油田、煉化等行業(yè)中的鎖斗，料倉(cāng)、反應(yīng)釜、分離器、氣力輸送，泵的隔離及各類管道，尤其是在磨損沖蝕性介質(zhì)的應(yīng)用中，更能表現(xiàn)出其卓越的性能。
Disc valves can be widely used in many industries, such as the locks, silos, reactors, separators, pneumatic conveying systems of the smelting, mining, power plants, gasifi cation, coal liquefaction, glass, ceramics, oil fi elds, refi ning industries, the pump isolation, and various pipelines, and the abrasive and erosive media in particular, where it demonstrates excellent performance.
