  物料(liào)切斷閥采(cǎi)用優質鋼(gāng)材焊接而(ér)成，其結構(gou)科學合理(li)🤩，緊湊獨特(tè)，操作靈活(huó)，維護方便(biàn)，密封性能(néng)可靠。其楔(xie)緊工😘作原(yuan)理使插闆(pǎn)越關越緊(jin)，使密封永(yǒng)遠處💛于良(liang)好狀态。而(ér)插闆一旦(dan)開啟，馬上(shàng)與密封面(mian)脫離，以保(bao)證密🈲封面(miàn)不受磨損(sun)，且密封面(mian)敞開式，物(wù)料無🌐法附(fù)着和沉積(jī)。此構造是(shi)⛹🏻‍♀️密封的關(guān)鍵💁所在。W表(biǎo)示密封面(miàn)為橡膠軟(ruǎn)密封，P表示(shi)密封面為(wei)合金硬密(mì)✊封。配🏃用不(bu)同的傳動(dòng)裝置滿足(zú)不同工況(kuang)需求。Z73為手(shǒu)輪傳動🎯，WZ73為(wéi)蝸輪傳動(dong)，DZ73為電動裝(zhuāng)置傳動，QZ73為(wéi)氣動裝置(zhì)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(zhǔ)要由閥體(ti)、插闆、密封(fēng)副、傳動杆(gǎn)及傳動裝(zhuāng)置⛹🏻‍♀️等部件(jian)組成。手動(dòng)物料切斷(duàn)閥由人工(gong)轉動手輪(lún)，沿順時針(zhēn)方向🈲為關(guān)，逆時針方(fang)向為開。由(you)旋轉螺母(mu)帶動傳動(dòng)杆作向上(shàng)運動，使插(chā)闆脫離密(mì)封面向上(shàng)位移，直至(zhi)全開，反之(zhī)為關。蝸輪(lún)傳動物料(liào)切斷閥由(yóu)人工轉動(dong)蝸輪裝置(zhi)手輪，順時(shi)針🧑🏾‍🤝‍🧑🏼方向為(wei)關，逆時針(zhēn)方向為開(kāi)，帶動蝸輪(lun)副旋轉從(cóng)而帶動傳(chuan)動杆向上(shang)運動，使插(cha)闆全開，反(fan)之全關。電(dian)👉動物料切(qiē)斷閥由Z型(xíng)電動裝置(zhi)得到💰指令(ling)動作旋轉(zhuǎn)螺母☁️帶動(dong)傳動杆作(zuo)運動，使插(chā)闆起到開(kai)關作用。氣(qi)動物料切(qie)斷閥由二(èr)位五通電(diàn)磁換向閥(fa)🌈控制，10A-5R氣動(dong)推杆帶動(dong)傳動杆作(zuo)往複運🏃🏻動(dòng)，使插闆起(qǐ)到開關作(zuò)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.

Usage explanation

l  安(ān)裝時必需(xū)清除閥門(mén)内腔雜物(wu)和污漬，請(qǐng)注意閥體(tǐ)♊上箭頭💋所(suo)指介質流(liú)向。兩法蘭(lán)連接時必(bì)需加密封(fēng)墊🍉片，然後(hou)均👉勻擰🏒緊(jǐn)螺栓。

l  安裝(zhuang)前先手動(dong)閥門一個(gè)周期，無異(yì)常現象方(fāng)可上線安(ān)🌈裝。

l  運行時(shí)應定期給(gěi)各傳動部(bu)分加潤滑(hua)油，定期檢(jiǎn)修⭐傳動裝(zhuang)⚽置。

l  若長期(qī)存放，請給(gěi)傳動部分(fèn)加潤滑油(yóu)，作防潮處(chù)理，不要露(lù)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
