Na'ura mai aiki da karfin ruwa wedge ƙofar bawul DN400 PN25

1. Bayani da Mahimman Fasalolin

Ƙofar Ƙofar Haɗaɗɗen Haɗaɗɗen Bawul ɗin Motsi na linzamin kwamfuta inda diski mai siffa (ƙofa) aka ɗaga ko saukar da shi ta na'urar motsa jiki don sarrafa kwararar ruwa.

Mabuɗin fasali na wannan girman da aji:

• Cikakken Ƙirar Ƙira: Diamita na ciki ya dace da bututu (DN400), yana haifar da raguwar matsa lamba sosai lokacin buɗewa cikakke kuma yana ba da izinin aladun bututun.
• Gudun Bidirectional: Ya dace da gudana ta kowace hanya.
• Rising Stem: Tushen yana tashi yayin da aka buɗe bawul, yana ba da alamar gani mai haske na matsayi na bawul.
• Ƙarfe-zuwa-ƙarfe Seling: Yawanci yana amfani da ƙugiya da zoben wurin zama waɗanda ke da wuyar fuska (misali, tare da Stellite) don yashwa da juriya.
• Ƙarfafa Gina: An ƙera shi don ɗaukar manyan matsi da ƙarfi, yana haifar da jiki mai nauyi da ɗorewa, sau da yawa daga simintin ƙarfe ko ƙarfe na ƙarfe.

2. Manyan Abubuwan

1. Jiki: Babban tsarin da ke ɗauke da matsi, yawanci ana yin shi daga Karfe Karfe (WCB) ko Bakin Karfe (CF8M/316SS). Ƙarshen masu ƙanƙara (misali, PN25/ASME B16.5 Class 150) daidai suke don DN400.
2. Bonnet: Bonted zuwa jiki, gidaje da tushe kuma yana ba da iyakacin matsa lamba. Sau da yawa ana amfani da katako mai tsayi don dalilai na rufewa.
3. Wedge (Kofar): Bangaren rufe maɓalli. Don PN25, Wedge mai sassauƙa ya zama gama gari. Yana da yanke ko tsagi a kewayen kewayenta wanda ke ba da damar ƙwanƙwasa ya ɗan ɗanɗana, inganta hatimi da ramawa ga ƙananan canje-canje a daidaitawar wurin zama saboda faɗaɗa zafi ko damuwa na bututu.
4. Karfe: Babban madaidaicin madauri mai ƙarfi (misali, SS420 ko 17-4PH Bakin Karfe) wanda ke watsa ƙarfi daga mai kunnawa zuwa tsinke.
5. Wuraren zama: zoben fuska masu wuya an matse ko a sanya su cikin jikin wanda tsinken ya rufe. Suna haifar da m rufe-kashe.
6. Shiryawa: Hatimi (sau da yawa graphite don yanayin zafi mai zafi) a kusa da tushe, wanda ke ƙunshe a cikin akwatin shaye-shaye, don hana yaɗuwar yanayi.
7. Na'ura mai aiki da karfin ruwa: Na'urar piston-style ko scotch yoke actuator wanda aka yi amfani da shi ta hanyar matsa lamba na hydraulic (yawanci mai). Yana ba da babban juzu'i / matsawa da ake buƙata don yin aiki da babban bawul ɗin DN400 akan babban matsa lamba.

3. Ka'idar Aiki

• Budewa: Ruwan na'ura mai aiki da karfin ruwa yana shiga cikin mai kunnawa, yana motsa fistan. Ana canza wannan motsi zuwa motsi na rotary (scotch yoke) ko motsi na layi (piston na layi) wanda ke jujjuya tushen bawul. Tushen zaren ya shiga cikin ƙugiya, yana ɗaga shi gaba ɗaya a cikin bonnet, ba tare da toshe hanyar kwarara ba.
• Rufewa: Ruwan na'ura mai ba da hanya tsakanin hanyoyin sadarwa yana jujjuya motsi. Tushen yana jujjuya kuma yana tura ƙugiya zuwa cikin rufaffiyar wuri, inda aka danne shi a kan zoben wurin zama guda biyu, yana haifar da hatimi.

Bayani mai mahimmanci: An tsara wannan bawul ɗin don keɓewa (cikakken buɗe ko rufe gabaɗaya). Bai kamata a yi amfani da shi ba don maƙarƙashiya ko sarrafa kwararar ruwa, saboda wannan zai haifar da girgizawa, cavitation, da saurin yashwar yanki da kujeru.

4. Aikace-aikace na yau da kullun

Saboda girmansa da ƙimar matsin lamba, ana amfani da wannan bawul wajen buƙatar aikace-aikacen masana'antu:

• Isar da Ruwa & Main Rarraba: Ware sassan manyan bututun mai.
• Shuka Wutar Lantarki: Tsarin ruwa mai sanyaya, layin ruwan ciyarwa.
• Ruwan Tsarin Masana'antu: Manyan masana'antu na masana'antu.
• Tsire-tsire masu narkewa: Layukan jujjuyawar matsin lamba (RO).
• Ma'adinai da Ma'adinai Processing: Slurry bututu (tare da dacewa kayan zabi).

5. Fa'idodi da rashin amfani

6. Muhimman ra'ayi don Zaɓi da Amfani

• Zaɓin Abu: Daidaita kayan jiki / yanki / wurin zama (WCB, WC6, CF8M, da sauransu) zuwa sabis na ruwa (ruwa, lalata, zazzabi).
• Ƙarshen Haɗi: Tabbatar da ƙa'idodin flange da fuskantar (RF, RTJ) sun dace da bututun.
• Naúrar Ƙarfin Ruwa (HPU): Bawul ɗin yana buƙatar HPU daban don samar da matsa lamba na hydraulic. Yi la'akari da saurin aiki da ake buƙata, matsa lamba, da sarrafawa (na gida/na nesa).
• Yanayin Rashin-Safe: Ana iya ƙayyade mai kunnawa azaman Fail-Open (FO), Rashin-Rufe (FC), ko Fail-in-Last-Position (FL) dangane da buƙatun aminci.
• Valve By-Pass: Don aikace-aikacen matsi mai ƙarfi, ƙaramin bawul ta hanyar wucewa (misali, DN50) galibi ana shigar da shi don daidaita matsa lamba a kan ƙugiya kafin buɗe babban bawul, yana rage ƙarfin aiki da ake buƙata.

A taƙaice, Ƙofar Ƙofar Haɗaɗɗiyar Wuta ta Hydraulic Wedge Valve DN400 PN25 babban aiki ne, dokin aiki mai nauyi don tsayawa gaba ɗaya ko fara kwararar ruwa a cikin manyan bututun matsa lamba. Ayyukan na'ura mai aiki da karfin ruwa yana sa ya dace da wuraren keɓe masu nisa ko na atomatik.
