1、() Special for 3X135MW Coal-fired Power Pla nt in Siha nouk Cambodia 電動(dòng)多層次金屬硬密封蝶閥 Motor-Operated multi-tiered metal hard sealing butterfly valve D943H 使 用 說(shuō) 明 書 Operation Instruction 閥門集團(tuán)有限公司 Valve Group Co., Ltd 使用說(shuō)明書 Operation Instruction 概述 Overview 該閥是我廠按最新標(biāo)準(zhǔn)設(shè)計(jì)，在吸收消化國(guó)內(nèi)外先進(jìn)技術(shù)的基礎(chǔ)上，而研制成功 的一種大口徑蝶閥結(jié)構(gòu)上

2、做了改進(jìn)，性能更加可靠，廣泛用于介質(zhì)為低、中、高 壓的水、泥沙水、海水等的泵站管路中，安裝在水泵出口處，作截止、調(diào)節(jié)之用。 It is a big caliber butterfly valve that designed according to newest standard upon digesti ng and assimilat ing adva need tech no logy from home and foreig n, which is improved in structure but with more reliable performa nee, is widely

3、used to pump pipe with media of water, cement sand and sea water in low, middle and high pressure, in stalled to outlet of water pump, used to close and regulate flow. 電動(dòng)法蘭式三維偏心多層次金屬硬密封蝶閥 Motor-operated Flange Type Three-dimensional Eccentric Multi-tiered Metal Hard Sealing Butterfly Valve 一、 結(jié)構(gòu)特點(diǎn)：

4、First: Con structi onal feature 1、三偏心結(jié)構(gòu) Three-dime nsio nal ecce ntric structure 由于該閥采取了三偏心結(jié)構(gòu)，從幾何形狀上使得閥座與蝶板密封圈在閥門整 個(gè)開關(guān)過(guò)程中完全脫離，這一獨(dú)特的偏心組合，既利用了凸輪效應(yīng)，又完全消除 了摩擦，從而實(shí)現(xiàn)了閥門在90啟閉行程中，閥座與蝶板上的多層彈性密封圈之間 無(wú)摩擦消除了因密封面的磨損而產(chǎn)生閥門泄露的可能，大大延長(zhǎng)了閥門的使用壽 命，閥門密封面上的比壓可通過(guò)外力矩的增減進(jìn)行作任意調(diào)整，使其密封更為可 靠，絕不會(huì)出現(xiàn)過(guò)關(guān)現(xiàn)象。 For the valve adopts three-

5、dime nsional structure, completely release the valve seat from the dished end sealing ring in the entire switching course, the unique eccentric comb in ati on utilizes cam effect and completely elimi nate the frictio n, so as to realize zero friction between valve seat and multi-tiered elastic seali

6、ng ring, eliminate the possibility of leakage caused by friction, greatly prolong the use life of valve. The specific pressure in the sealing face of valve could be regulated randomly through externally applied torque, make seal more credible, without phe nomenon of pass. 2、多層次彈性金屬密封圈 Multi-tiered e

7、lastic metal seali ng ring 真空蝶閥利用安裝在蝶板上的多層次彈性密封圈來(lái)實(shí)現(xiàn)真正的零泄漏。蝶板上 的多層次彈性密封圈是由不銹鋼片和優(yōu)質(zhì)石棉板一層一層相互疊加壓制而成。它 即具備金屬密封副的硬度及較好的抗摩擦性能，又具有軟密封副的彈性及較好的 密封性能，當(dāng)外力閥桿通過(guò)施加扭矩時(shí)，也使密封圈徑向壓縮和柔動(dòng)，而密封圈 與閥座接觸面是 錐中錐 的結(jié)構(gòu)，兩個(gè)錐體均為斜錐體，密封圈與閥座之間的接 觸角產(chǎn)生輕微的 楔塊效應(yīng)”使密封圈發(fā)生柔動(dòng)和徑向壓縮。正是由于密封圈與 閥座之間的均勻接觸及密封圈的柔性使閥座周邊產(chǎn)生均勻荷載，從而用最小的力 矩實(shí)現(xiàn)最嚴(yán)密的切斷，致使閥門達(dá)到零泄漏。

8、The vacuum butterfly valve adopts multi-tiered elastic sealing ring in the butterfly board to realize genuine zero leakage. The multi-tiered elastic sealing ring in the butterfly board is overlapped with stai nless steel plate and excelle nt asbestos board one by on e. It equips hard ness of metal s

9、eali ng with better an tifrict ion performa nee, but also has elasticity of soft seal with better sealing performanee. When the valve rod exert torque, but also make seal ring compress and move vertically, the in terface betwee n seal ring and valve seat is “one-shaped structure, two cones are both

10、oblique cones, the con tact ing corner will produce light wedge effect, make seal ring move and compress vertically. For the uniform con tact betwee n seali ng ring and valve seat, and the soft ness of seal ring make valve seat produce homoge neous load ing, so as to realize most stri ngent with mi

11、nimum torque, reach zero leakage. 3、閥門閥軸底部密封結(jié)構(gòu) The hermetically-sealed con struct ion in the bottom of valve and shaft 閥門閥軸底部密封采用金屬纏繞平墊加優(yōu)質(zhì)橡膠“ O型圈雙重密封結(jié)構(gòu)，閥底 端蓋與閥體連接采用凹凸法蘭式結(jié)構(gòu)，密封墊為包邊金屬纏繞墊片，該墊即有較 高強(qiáng)度，又有可靠密封性能，另外在自潤(rùn)滑軸承上部，閥桿與閥體之間設(shè)有一套“O” 型圈密封裝置，即有效地防止了閥門底部的外泄漏，又對(duì)自潤(rùn)滑軸承起到了防護(hù) 作用。 It adopts metal winding gasket

12、 plus excellent rubber O” ring double seal structure, applies con cave-c onvex flange structure to connect bottom valve end cover and valve body, the gasket is metal winding, with high stre ngth and reliable seali ng performa nee. Besides, in the upper section of self-lubricant bearing, there is one

13、 O” sealing arra ngeme nt betwee n valve stem and body, effectively preve nt exter nal leakage in the bottom but also protect the self-lubrica nt beari ng. 4、蝶板密封圈可以調(diào)節(jié)，這有利于裝配與維修 Butterfly board sealing ring could be regulated, is in favor of installing and maintenan ce. 5、通過(guò)擇用合適的材料，使得閥門具有耐低（高）溫，耐腐蝕的

14、性能。 Make valve temperature resista nee and an ticorrosi on through choos ing proper material. 6蝶板的流線形設(shè)計(jì)，使得流體阻力損失小，可謂是一種節(jié)能型產(chǎn)品。 The streamline design of butterfly board causes less loss of fluid resistance is an energy sav ing product. 7、由于獨(dú)特的密封結(jié)構(gòu)，使閥門操作靈活、省力、方便、可靠。 The unique hermetically-sealed con s
