Structure characteristic:

  物料切(qie)斷閥采用優質(zhì)鋼材焊接而成(chéng)，其結構科學合(he)理，緊湊獨特，操(cāo)作靈活，維護方(fāng)便，密封性能可(kě)靠。其楔緊工作(zuo)原理使插闆越(yue)關越緊，使密封(feng)永遠處🤟于良好(hǎo)狀态。而插闆一(yī)旦開啟👄，馬上與(yu)密封面脫離⚽，以(yi)保證密封面不(bu)受♋磨損，且密封(fēng)面敞開式，物料(liao)無法附着和沉(chen)積。此構造是密(mi)封的關鍵所在(zài)。W表示密💃🏻封面為(wei)橡膠軟密封，P表(biǎo)示密封面為合(he)金硬密🈲封。配用(yong)不同的傳動裝(zhuang)置滿足不同工(gōng)況需求。Z73為手輪(lun)傳動，WZ73為蝸輪傳(chuan)動，DZ73為電動裝置(zhi)傳動，QZ73為氣動裝(zhuang)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(wù)料切斷閥主要(yào)由閥體、插闆、密(mì)封副、傳動杆及(jí)傳👌動裝置等部(bù)🍓件組成。手動物(wù)料切斷閥由人(ren)工轉動手輪，沿(yan)順時針方向為(wei)關，逆時針方向(xiang)為開。由旋轉☂️螺(luo)母帶動傳動♍杆(gan)作向上運動，使(shǐ)插闆脫離密封(fēng)面向上位移，直(zhí)至全開，反之為(wéi)關。蝸輪傳動物(wu)料切斷閥由人(rén)工轉動蝸輪裝(zhuang)置手輪，順時針(zhēn)方向為關，逆✂️時(shi)針方向為開，帶(dài)動蝸輪副旋轉(zhuan)從而帶動傳動(dòng)杆向上運動🌈，使(shi)插闆全開，反之(zhi)全關。電🚩動物料(liào)切斷閥由Z型電(dian)動裝置得到指(zhǐ)令動作旋轉螺(luó)母帶動傳動🌏杆(gan)作運動，使插闆(pǎn)起到開關作用(yong)。氣動物料切♊斷(duàn)閥由二位五通(tōng)電磁換向閥控(kòng)制，10A-5R氣動推杆帶(dai)動傳動㊙️杆作往(wang)複運動，使插闆(pǎn)起到🏃‍♂️開關作用(yong)。

  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(ming)：

Usage explanation

l  安裝時必需清(qing)除閥門内腔雜(zá)物和污漬，請注(zhù)意閥體上箭頭(tóu)所指介質流向(xiàng)。兩法蘭連接時(shi)必需加密封墊(niàn)片，然後均❗勻擰(nǐng)🎯緊螺栓。

l  安裝前(qián)先手動閥門一(yī)個周期，無異常(cháng)現象方可上線(xiàn)安裝。

l  運行時應(ying)定期給各傳動(dòng)部分加潤滑油(you)，定期檢修♉傳動(dòng)🛀🏻裝置。

l  若長期存(cún)放，請給傳動部(bù)分加潤滑油，作(zuo)防潮處理，不要(yao)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
