產(chǎn)品概述
此電液動暗板刀型閘閥是閘閥中的新品種，體積小，重量輕，輕型節(jié)材，是污水、煤漿、糖漿、泥漿、空氣、渣水混合物、供水、造紙、礦山等行業(yè)中的理想產(chǎn)品。
暗板刀型閘閥采用金屬對金屬的硬密封，或采用金屬對橡膠的軟密封。在開啟和關(guān)閉的過程中，閘板與密封面采用了特殊的設(shè)計，摩擦較少，經(jīng)久耐用。
此種刀形閘的上密封突破了常規(guī)的密封形式，采用上蓋結(jié)構(gòu)，使得上密封由大面積的矩形密封改成了小面積的圓周密封，密封性能大大提高。在圓周密封的基礎(chǔ)上，又采用了目前國際上*的浮動密封結(jié)構(gòu)，使得上密封達到了與管道同壽命的程度，從而整體上提高了閥門的使用壽命。
此種閘閥在手輪頂部加裝封套裝置后，可以使閥門活動部件全部處于封閉狀態(tài)，閘板和閥桿的絲桿傳動不會因潤滑油干枯而卡澀。特別適合在粉塵及干燥的惡劣環(huán)境中長期正常工作。
注：可根據(jù)使用單位的環(huán)境和要求來設(shè)計與生產(chǎn)，適合用戶的安裝和使用。
電液動暗板刀型閘閥通過電液聯(lián)動裝置往復推位來控制閥門的開啟和關(guān)閉，如配置傳感器或數(shù)字顯示裝置，可進行遠距離，高空的危險地區(qū)集中或程序控制，廣泛應(yīng)用于冶金、電力、煤炭、礦山、水利等行業(yè)，是一種應(yīng)用性強的新型更新替代產(chǎn)品。

Product introduction
This knife gate valve is a new generation gate valve characteristic of small construction, low weight, and high material utilization. It is an ideal product for such sectors including sewage disposal, coal slurry, syrup, sludge, air, slag-water mix, water supply, papermaking, mining, etc.
The knife gate valve adopts metal-to-metal hard sealing or metal-to-rubber soft sealing. In the processing of valve switching on/off, the gate plate and sealing face are provided with special design, featuring limited friction and high durability.
The sealing of the knife gate valve represents a breakthrough in traditional sealing form. Upper cap structure changes large area rectangular sealing face of the upper sealing to small area circular sealing, with much enhanced sealing performance. Based on circular sealing, the valve is further provided with latest floating sealing construction in the world. Thus the upper sealing shares the same useful life with pipeline, so the overall useful life of the valve increases.
After envelope is added to the top of hａnd wheel, all the moving parts of the gate valve will be enclosed. Therefore, the rotation of lead screws between gate plate and stem will not block because of short supply of lubricating oil. In particular, the valve is applicable for long-term service in severely dusty and dry environment.
Note: The valve could be designed and manufactured based on client's site conditions and requirements for better installation and application.
The product controls opening and closing of valve by the reciprocating pushing effect of electric-hydraulic linkage. It can bring about centralized or programmed control distantly for high-attitude dangerous area by mounting optional sensor or digital display. It is widely used in such sectors including metallurgy, electricity generation, coal mining, mining, water conservancy, etc., representing a kind of highly practical, upgraded substitute.
