德國奧萊斯OLES進口刀型閘閥

【進口刀型閘閥】詳細說明：

刀形閘閥是閘閥的新品種，體積小，重量輕，輕型節(jié)材，是污水、煤漿、泥漿、空氣、渣水混合物、供水、造紙、礦山等待業(yè)中的理想產(chǎn)品。    

2.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，磨擦較少，經(jīng)久耐用。    

3.氣動暗桿式刀形閘閥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。    

4.氣動暗桿式刀形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*正常工作。

Knife gate valve is a new type of gate valve. It is small in size, light in weight and light in material saving. It is an ideal product in sewage, coal slurry, slurry, air, slag-water mixture, water supply, paper making and mine waiting industries. _

2. Hard metal-to-metal seals or soft METAL-TO-RUBBER seals are used. In the process of opening and closing, the gate and sealing surface adopt special design, less friction, durable. _

3. The upper seal of pneumatic hidden rod knife gate valve breaks through the conventional seal form and adopts the upper cover structure, which makes the upper seal change from rectangular seal with large area to circular seal with small area, and the sealing performance is greatly improved. Based on the circumferential seal, the advanced floating seal structure in the world is adopted, which makes the upper seal reach the same life as the pipeline, thus improving the service life of the valve as a whole. _

4. Pneumatic hidden-rod knife gate valve can make all the moving parts of the valve closed after the top of the handwheel is fitted with a jacket device. The screw drive of the gate and the stem will not be jammed by the dry lubricant. Especially suitable for long-term normal work in dust and dry harsh environment.

【進口刀型閘閥】用途：

刀形閘閥是較為復(fù)雜的自動化控制儀表，由多種氣動元件及閥體組成。多用于要求快速切斷或開啟的場合。

暗桿氣動刀型閘閥廣泛使用于油田、化工、煤礦、電站、科研、船舶、環(huán)保、工程建設(shè)、機械、冶金、化肥、造紙、能源、生物醫(yī)藥、制冷、食品等各種領(lǐng)域等行業(yè)。

【進口刀型閘閥】安裝說明：

1. 刀型閘閥安裝前須檢查閥門腔內(nèi)和密封面等部位，不允許有污物或砂粒附著；

2. 各連接部位螺栓，要求均勻擰緊；

3. 檢查填料部位要求壓緊，既保證填料的密封性，也要保證閘板開啟靈活；

4. 用戶在安裝閥門前，必須校對閥門型號，連接尺寸及注意介質(zhì)流向，保證與閥門要求*性；

5. 用戶在安裝閥門時，必須預(yù)留閥門驅(qū)動的必要空間；

6. 驅(qū)動裝置的接線須按線路圖進行；
