物料切斷閥是我(wǒ)公司引(yǐn)進美國ITT Engineered的技(jì)術，開發研(yán)制的新一代産品。廣泛應用于建材、冶金、礦(kuàng)山、石油、化工、玻璃等行業的管道或氣(qì)力輸送系統中，作切斷或調節(jiē)用。

  This valve is the new designed product importing new technology of American company ITT Engineered. It is used to cut off or adjust valve, which is applied in pipe or pneumatic transportation system in building material, metallurgy, mining, oil, chemical and glass industries etc

結構特點：

Structure characteristic:

  物料切(qiē)斷閥采用優質鋼材(cái)焊接而成，其結構科學合理，緊湊獨特，操(cāo)作靈活，維護方便，密封性能可靠。其楔緊工作原理使插(chā)闆越關越緊，使密(mì)封(fēng)永遠處于良好(hǎo)狀态。而插闆一旦開啟，馬上與(yǔ)密封(fēng)面脫離，以保證(zhèng)密封面不受磨損，且密封面敞開式，物料無法附(fù)着和沉積。此構造是密(mì)封的關鍵所在。W表示密封面為橡膠軟密封，P表示密封面為合金硬密封。配用不同的傳動裝(zhuāng)置滿足不同工況需求。Z73為手輪傳動，WZ73為蝸(wō)輪傳動，DZ73為電動裝置傳動，QZ73為氣動裝置傳動。

  The valve is welded in fine steel, having the features of compact and scientific structure, hand to operate, easy to maintenance and reliable sealing. The working principle is choking, the sealing is always in the best state while the disc is closed. The disc separates from sealing surface when it is opened, which avoids abrasion of the sealing surface. The sealing surface is in open state and the material cannot cohere or deposit, which the key to the sealing. W means the sealing surface is rubber soft sealing, P means the sealing surface is alloy hard sealing. It can meet different requirement of working conditions equipped with different transmission devices. Z73 denotes hand wheel drive, WZ73 denotes worm gear drive, DZ73 denotes electric device drive and QZ73 pneumatic device drive.

Working principle

  物料切斷閥主要(yào)由閥體(tǐ)、插闆、密封副、傳動杆及(jí)傳動裝置(zhì)等部件組成。手動物料切斷閥由人(rén)工轉動手輪，沿順時針方(fāng)向為關，逆時針方向為開。由旋轉螺母帶動(dòng)傳動杆作向上(shàng)運動(dòng)，使插闆脫離密封面向上(shàng)位(wèi)移，直至全(quán)開，反之為關。蝸(wō)輪傳動物料切斷(duàn)閥由人(rén)工轉動蝸輪裝置手輪，順時針方向為關，逆時針方向為開，帶動蝸輪副旋轉從而(ér)帶動傳動(dòng)杆向上運動，使(shǐ)插闆全開，反之(zhī)全關。電動物(wù)料切斷閥由Z型電(diàn)動裝置得(dé)到指令(lìng)動作旋轉(zhuǎn)螺母帶動傳動杆作運動，使插闆(pǎn)起(qǐ)到開關作用。氣動物料切斷(duàn)閥由二位五通(tōng)電磁(cí)換向閥控制(zhì)，10A-5R氣動推杆帶動傳(chuán)動杆作往複運動，使插闆起到開關(guān)作用。

  The valve is mainly made up of body, inserting disc, sealing pairs, transmission pole and transmission device etc. The hand wheel of the manual valve is rotated in clockwise and closes the valve, anticlockwise rotation means open. The transmission pole moves upwards and makes the disc separate from sealing surface and move upwards until the valve is fully opened. The hand wheel of worm gear drive valve is rotated by hand. Clockwise rotation means close and anticlockwise means open. The transmission pole moves upward, the worm gear pairs rotate until the disc is fully opened. Type Z electric device of electric valve receives the order and rotates nut to drive the transmission pole in order to open or close the disc. The pneumatic valve is controlled by two-bite five-way electromagnetism reversal valve. Type 10A-5R pneumatic draw stem drives the transmission pole move reciprocally to open or close the disc.

使用說明：

Usage explanation

l  安(ān)裝(zhuāng)時(shí)必需清除閥門内(nèi)腔雜物和污漬，請注意閥體(tǐ)上箭頭所指(zhǐ)介質流向(xiàng)。兩法蘭連接時必需加密(mì)封墊片，然後均勻(yún)擰(nǐng)緊螺栓。

l  安裝前先手動閥門一個周期，無異常現象方可上線安裝。

l  運行時應定期給各傳動部分加潤滑油，定期檢修傳動(dòng)裝置(zhì)。

l  若長期存(cún)放，請給(gěi)傳動部分加潤滑油，作(zuò)防潮處(chù)理，不要(yào)露天堆置。

l   Clear out the lumber and dust in valve chest when install. Pay attention to the medium direction indicated by arrow. Add seal shim between two flanges and then screw the bolt.

l   Operate the valve by hand for a period of time before install. When there is no anomaly, the valve can be installed.

l   Add lubricant to the transmission parts and check the transmission device regularly.

Add lubricant to the transmission parts when it is stored for a long time. It cannot be put in the air and treatment of damp proof
