Zisanu ntchito minda ndi ubwino kukwiriridwa mpira valavu malangizo kwa valavu mpira Full magetsi kuwotcherera mpira valavu zosiyanasiyana makina zida: zosiyanasiyana kutentha mankhwala ndondomeko payipi, zosiyanasiyana mafakitale kupanga liquefied mpweya ndi mapaipi Kutentha. Ma valve okwiriridwa pawiri plugging ndi kutulutsa ntchito torsion kasupe torque kusinthasintha mpando, ziribe kanthu valavu ali lotseguka kapena kutsekedwa boma, chapamwamba, chapakati ndi kutsika mbali mpando umapanga chotchinga madzi, mafuta njira mbale mu posungira patsekeke malinga ndi valavu kutulutsa. metabolism. Kuthamanga kwachangu kwa valavu yokwiriridwa mpira kungapangitse kutentha kwa chubu la impso kukwera ndi kuchititsa kusintha kwachilendo, popanda kufunikira kudalira valavu, ndipo ntchito ya mpando ikhoza kukhala yopumula kwathunthu, kuonetsetsa chitetezo cha valve mu kayendedwe ka zinthu zamadzimadzi ndizofunikira kwambiri. 1, zonse magetsi kuwotcherera valavu mpira kwa mpweya mzinda: liquefied mpweya katundu payipi, msewu waukulu ndi nthambi iliyonse ntchito payipi payipi, etc. 3, valavu yowotcherera yamagetsi yamagetsi yosinthira kutentha: chitoliro ndi kuzungulira kutseguka ndikutseka. 4, smelter: mitundu yonse ya payipi yamadzimadzi, payipi yosankha mpweya wotulutsa mpweya, mpweya wamadzimadzi ndi mapaipi opangira magetsi, payipi yoperekera mafuta. 5, zonse magetsi kuwotcherera mpira valavu zosiyanasiyana makina zida: zosiyanasiyana mapaipi kutentha ndondomeko mankhwala, zosiyanasiyana kupanga mafakitale a liquefied mpweya ndi mapaipi Kutentha. Ma valve okwiriridwa pawiri plugging ndi kutulutsa ntchito torsion kasupe torque kusinthasintha mpando, ziribe kanthu valavu ali lotseguka kapena kutsekedwa boma, chapamwamba, chapakati ndi kutsika mbali mpando umapanga chotchinga madzi, mafuta njira mbale mu posungira patsekeke malinga ndi valavu kutulutsa. metabolism. Kuthamanga kwachangu kwa valve yokwiriridwa mpira kumatha kupangitsa kuti kutentha kwa chubu la impso kukwera ndikupangitsa kusintha kwachilendo, popanda kufunikira kudalira valavu, ndipo ntchito ya mpandoyo imatha kukhala yopumira yokhayokha, yomwe ingapangitse kuonetsetsa chitetezo cha valve mu kayendedwe ka zinthu zamadzimadzi ndizofunikira kwambiri. Ubwino wa valavu yokwiriridwa mpira 1, kusindikiza kupulumutsa mafuta mwadzidzidzi: chifukwa cha zinthu zonyansa zomwe zili mu chinthucho kapena ngozi zamoto zimayambitsa kusayembekezeka kwa mpando wa valve, valavu yamafuta imabweretsa kulumikizana ndi jekeseni wamafuta, pampu yotumizidwa kunja imapulumutsa nthawi komanso kuyesetsa kubaya mafuta osindikizira pamalo osindikizira, kuchepetsa kutayikira. 2. Kusindikizidwa kwa tsinde la valve ndi torque yapamwamba yogwiritsira ntchito: kuwonjezera pa mphete yosindikizira, O-ring imawonjezeredwa pa kapu yonyamula wononga, kusindikiza njira ziwiri kumatsimikizira kukhazikika kwa tsinde la valve; Kuphatikiza kwa chiyero chapamwamba cha graphite kulongedza ndi kusindikiza mafuta kumapangitsa kuti tsinde lituluke pambuyo pa moto wochepa kwambiri. Mapiritsi a tsinde ndi ma thrust bearings amapangitsa kuti valavu ikhale yosavuta kugwira ntchito. 3. Chitoliro chokwanira cham'mimba mwake kapena m'mimba mwake: Chitoliro chokwanira chokwanira kapena mawonekedwe ochepetsedwa angagwiritsidwe ntchito molingana ndi momwe zinthu zilili. Kutalika konse kwa valavu yodzaza ndi m'mimba mwake kumagwirizana ndi m'mimba mwake mwadzina la payipi, yomwe imathandizira kuyeretsa mapaipi. 4, tsinde la valve likhoza kukulitsidwa: malinga ndi zosowa za msonkhano kapena ntchito, tsinde la valve likhoza kukulitsidwa. Anawonjezera ndodo mpira valavu, makamaka oyenera mpweya m'tauni ndi malo ena amene ayenera mwachindunji kukwiriridwa mipope yayala. Zowonjezera tsinde la valve monga momwe kasitomala amafunira. 5. Zosavuta kugwiritsa ntchito: mpando wa valve ndi tsinde lozungulira lokhala ndi kukana kwazing'ono komanso kudzipaka bwino kwambiri kumasankhidwa kuti achepetse torque ya valve. Choncho, ma valve okwiriridwa mpira amatha kugwira ntchito mosinthasintha kwa valve kwa nthawi yaitali ngakhale kuti sapereka mafuta osindikizira. Valavu yowongolera pamanja ndi rocker kapena gear, valavu yamagetsi yamagetsi kapena pneumatic yoyendetsedwa ndi chipangizo chamagetsi kapena chipangizo cha pneumatic, pangani mpirawo kuzungulira 90. Tsegulani kapena kutseka valavu. Tsinde la valve yoyendetsedwa ndi manja limayikidwa pamwamba. Concave poyambira azimuth ndi kutalika malangizo a spinner ndi malangizo otaya njira ndi lotseguka, ndi ofukula malangizo otaya katundu chatsekedwa. Valavu yosungirako nthawi yayitali iyenera kusungidwa nthawi zonse, *** zinyalala. Ayenera kumvetsera kuyeretsa pamwamba, kupewa kuwonongeka kwa pamwamba. Musanamangidwe kuti muyang'ane njira ya valve ndi pamwamba, ngati pali madontho, muyenera kusankha chopukuta choyera. Khwerero 1: Gulu Langizoli limakhudza m'mimba mwake mwadzina DN15mm~500mm(1/2"~20"), m'mimba mwake mwadzina PN1.6MPa~10MPa(ANSI> 2. Main ntchito 2.1 kiyi ntchito kutsegula kapena kutseka mapaipi ndi makina. Gwiritsani ntchito valavu ya 2.2.1 Carbon steel valve ingagwiritse ntchito madzi, nthunzi, dizilo ndi zipangizo zina. 2.2 130 ℃ PTFE galasi CHIKWANGWANI ≤160 ℃ PPL(admixture polystyrene)≤300℃ Khwerero 3: Mapangidwe 3.1 Mpira mawonekedwe valavu akuwonetsedwa Chithunzi 1 3.2 Zigawo Consumable kusindikiza gaskets, kulongedza PTFE kapena flexible graphite, 441 odalirika Mavavu owongolera pamanja amagwiritsa ntchito chida cha rocker kapena giya, valavu yamagetsi kapena pneumatic yoyendetsedwa ndi chipangizo chamagetsi kapena chipangizo cha pneumatic, kuti mpirawo uzungulira 90. Tsegulani kapena kutseka valavu 4.2 Pansi pa tsinde lojambulapo concave groove kutalika kwa mayendedwe a spinner ndi njira yoyendetsera njira imatsegulidwa, ndipo njira yowongoka ya kayendedwe ka katundu imatsekedwa. 4.3 Zizindikiro zotsegulira ndi kutseka kwa ma valve a mpira wamagetsi ndi pneumatic amadziwika ndi chizindikiro cha malo mu chipangizo chamagetsi ndi chipangizo cha pneumatic. 5. Kusungirako, kukonza, kukhazikitsa ndi kugwiritsa ntchito 5.1 Valavu iyenera kusungidwa m'chipinda chouma, chopanda mpweya. Mbali zonse ziwiri za chitetezo cha valve ziyenera kutsekedwa. 5.2 Ma valve osungira nthawi yayitali ayenera kusungidwa nthawi zonse, kutaya. Ayenera kumvetsera kuyeretsa pamwamba, kupewa kuwonongeka kwa pamwamba. 5.3 Musanamangidwe, yang'anani mosamala ngati chizindikiro cha valve chikugwirizana ndi zofunikira zogwiritsira ntchito. 5.4 Musanamangidwe, yang'anani njira ya valve ndi pamwamba. Ngati pali madontho, ayeretseni ndi matawulo oyeretsera. 5.5 Yang'anani ngati zolongedzazo zapanikizana musanamangidwe, ndikuwonetsetsa kulimba kwa kulongedza. Pa nthawi yomweyi, kuzungulira kwa tsinde la valve sikungalephereke. Mavavu a 5.6 ayenera kukhala otseguka pomaliza kuyika dongosolo kapena kuyesa kwa mapaipi a hydrostatic. 5.7 Mpira uyenera kutsegulidwa kapena kutsekedwa musanagwiritse ntchito, ndipo gawo la mpira sayenera kutsegulidwa kuti lisinthe valavu. 5.8 Potsegula kapena kutseka valavu yamanja, rocker iyenera kugwiritsidwa ntchito kutsegula kapena kutseka, ndipo thandizo la ndalama zothandizira ndalama kapena zida zina siziyenera kugwiritsidwa ntchito. 5.9 Kuyika kwa ma valve kumayenera kusamalidwa nthawi zonse kuti muwone ngati pali kuwonongeka kulikonse komanso kulongedza kwa gasket. Ngati kuwonongeka kuli kosavomerezeka, kumayenera kukonzedwa ndikusinthidwa munthawi yake. 5.10 Pamakina otumizira ma valve amagetsi ndi pneumatic, chonde onani "Buku Logwiritsa Ntchito Chida Chamagetsi cha Valve" ndi "Buku Logwiritsa Ntchito Chida cha Valve Pneumatic" posungira, kukonza, kukhazikitsa ndi kugwiritsa ntchito.
