物料切斷閥是(shì)我公司引進美(mei)國ITT Engineered的技術，開發(fā)研制的新一代(dài)産品。廣泛應用(yong)于建材、冶金、礦(kuàng)山、石油、化工、玻(bō)璃等🎯行業的管(guǎn)道或氣力輸送(song)系統中，作切斷(duàn)或調節用。

  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(gou)特點：

Structure characteristic:

  物料切斷(duan)閥采用優質鋼(gāng)材焊接而成，其(qi)結構科學合🍉理(lǐ)，緊湊獨特，操作(zuo)靈活，維護方便(bian)，密封性能可靠(kào)。其楔緊工作原(yuán)理使插闆越關(guān)越緊，使密封永(yǒng)遠處于良好狀(zhuàng)态。而㊙️插闆一旦(dàn)開啟，馬上與密(mi)封面脫離，以保(bao)證密🏒封面不受(shou)磨損，且密封面(miàn)敞開式，物料無(wu)法附着和沉👌積(jī)。此構造是密封(feng)的關鍵所在。W表(biǎo)示密封面為橡(xiàng)膠軟密封，P表示(shì)密封面為合金(jin)硬密封。配用不(bu)同的傳動裝置(zhì)滿足不同工況(kuang)需求。Z73為手輪傳(chuán)動，WZ73為蝸輪傳動(dòng)，DZ73為電動裝置傳(chuán)動，QZ73為氣動裝置(zhi)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(liào)切斷閥主要由(you)閥體、插闆、密封(fēng)副、傳動杆及傳(chuán)動裝置🔱等部件(jian)組成。手動物料(liào)切斷閥由人工(gōng)轉動🌂手輪，沿順(shùn)時針⭐方向為關(guān)，逆時針方向為(wei)開。由旋轉㊙️螺母(mǔ)帶動傳動杆作(zuo)向上運動，使插(chā)闆脫離密封面(mian)⭐向上位移，直至(zhì)全開，反之為關(guān)。蝸輪傳動物料(liao)切斷閥由人工(gōng)轉🌂動蝸輪裝置(zhi)手輪，順時針方(fāng)向為關，逆時針(zhēn)方向為開，帶動(dòng)蝸輪副旋轉從(cong)而帶動傳動杆(gǎn)向上運動，使插(chā)闆全開，反之全(quan)關。電動物料切(qiē)斷閥由Z型電動(dòng)裝置得到✊指令(lìng)動作旋轉螺母(mu)帶動傳動杆作(zuo)運動，使插闆起(qi)到開關作用。氣(qì)動物料切斷閥(fa)☎️由二位五通電(dian)磁換向閥控制(zhì)，10A-5R氣動推杆帶動(dong)傳動杆作往複(fu)運🏃動，使插闆起(qǐ)到開關作用。

  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)裝時必需清除(chu)閥門内腔雜物(wù)和污漬，請注意(yì)閥🏃🏻體上✌️箭頭所(suǒ)指介質流向。兩(liang)法蘭連接時必(bì)需加密封墊片(piàn)，然後均勻擰🌏緊(jin)螺㊙️栓。

l  安裝前先(xian)手動閥門一個(ge)周期，無異常現(xiàn)象方可上線安(ān)裝。

l  運行時應定(dìng)期給各傳動部(bù)分加潤滑油，定(ding)期檢修傳動☂️裝(zhuāng)置。

l  若長期存放(fàng)，請給傳動部分(fèn)加潤滑油，作防(fang)潮處理，不要露(lu)😄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
