盤閥

Disc Valve

盤閥是通過滑動圓盤來實現開關的一種快開快關型閥門。其設計專門針對帶有磨損、沖蝕特性的物料，它能在惡劣工況下連續長期的正常工作。
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.

它獨有的硬密封面具有自研磨作用，使其在磨損、沖蝕物料上應用的過程中不斷提高密封性，壽命要比其他閥門長好幾倍。
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.

特殊設計 Special Design

閥桿密封的設計
閥桿和閥體的密封分高溫 G 型和低溫 P 型兩種，<200℃時使用 V 型 PTFE 環作為閥桿的填料，V 型 PTFE 可以減少較大溫差變化造成的外漏；≥200℃時使用石墨環和高碳盤根作為閥桿的填料并配以碟簧承載，以保證長期密封。
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.
