Valavu yachitetezo cha boiler yodziwikiratu kuwunika kolakwika kwa ma valve achitetezo a malasha

Vavu yachitetezo cha boiler yachitetezo chodziwika bwino kuwunika kofunikira kwa valavu yamoto yamoto ya malasha Chidule: kusanthula kutayikira kwa valavu yachitetezo cha boiler, kutayikira kwapamadzi, kukhathamira kwa ma valve otetezera pambuyo poti valavu yopumirayo sichitapo kanthu, mpando wa valve wotetezera wotsalira kuchedwa kwa valve. kubwerera kumpando kumbuyo kwa nthawi yaitali ndi kutsika kwapansi kumbuyo kwa valve yotetezera, kuthamanga kwafupipafupi ndi flutter ndi zina zomwe zimayambitsa zolakwika, ndikuyika patsogolo yankho la chifukwa cha vutoli. 1. Zofunikira pachitetezo cha valavu yamoto wowotchera malasha wowotcha nthunzi mpweya mphamvu ndi wamkulu kuposa 0.5t/h, osachepera 2 mavavu chitetezo anaika, ovotera evaporation mphamvu ndi zosakwana kapena ofanana 0.5t/h, osachepera 1 chitetezo. valavu. Pamene mphamvu yotenthetsera ya boiler yamadzi otentha ndi yayikulu kuposa 1.4MW, mavavu otetezedwa a 2 adzayikidwa; Pamene kutentha kwapakati kumakhala kochepa kapena kofanana ndi 1.4MW, osachepera 1 valve yotetezera iyenera kuikidwa. Malo olekanitsa a economizer, chotengera chotenthetsera champhamvu cha nthunzi, chiyenera kukhala ndi valavu yachitetezo. Boiler yokhala ndi mphamvu ya nthunzi yochepera 0.1mpa imatha kugwiritsa ntchito valavu yotetezedwa yolemera kwambiri kapena chida chachitetezo chamtundu wamadzi. Valavu yotetezera iyenera kuikidwa molunjika, ndipo iyenera kuikidwa mu ng'oma, malo apamwamba kwambiri a bokosi losonkhanitsa. Pakati pa valavu yotetezera ndi ng'oma kapena pakati pa valavu yotetezera ndi bokosi losonkhanitsa, sipadzakhala chitoliro chotulukira ndi valavu ya nthunzi. Nthunzi YONSE YOTSITSA NTCHITO YA valavu yotetezera iyenera kukhala yokulirapo kuposa kuphulika kwa kutentha kwa boiler, ndipo ma valve onse otetezera pa ng'oma ndi superheater atatsegulidwa, kuthamanga kwa nthunzi mu ng'oma sikuyenera kupitirira nthawi 1.1 mphamvu ya mapangidwe. Kutulutsa kwamphamvu kwa valavu yachitetezo cha superheater kuyenera kuwonetsetsa kuti chotenthetsera chimakhala ndi kuzizirira kokwanira pansi pa voliyumu yotulutsa ndipo sichidzawotchedwa. Valavu yachitetezo cha boiler yoyimirira iyenera kukhala ndi chida chotsatirachi: valavu yachitetezo chamtundu wa masika iyenera kukhala ndi chogwirizira ndikuletsa chipangizo chosinthira. Valavu yachitetezo chamtundu wa lever iyenera kukhala ndi chipangizo choletsa kulemera kwake kuti zisasunthike palokha komanso chimango chowongolera kuti chiwongolerocho chisatuluke. Valavu yoletsa kulemera iyenera kukhala ndi chipangizo choletsa kulemera kwake kuti zisawuluke. Kwa ma boiler omwe ali ndi mphamvu ya nthunzi yocheperako kapena yofanana ndi 3.82Mpa, chitetezo chapakhosi chizikhala chosachepera 25mm; Kwa ma boiler okhala ndi kuthamanga kwa nthunzi wamkulu kuposa 3.82Mpa, makulidwe a mmero wa valavu yopumira sikuyenera kuchepera 20mm. Ma valve angapo otetezera amaikidwa pa chitoliro chachifupi cholumikizidwa mwachindunji ndi ng'oma, ndipo gawo laling'ono la chitoliro lalifupi siliyenera kukhala locheperapo kuchuluka kwa chitoliro cha chitoliro cha ma valve onse otetezera. Valavu yotetezera iyenera kukhala ndi chitoliro chotulutsa mpweya, chitoliro chotulutsa mpweya chiyenera kukhala panja momwe zingathere, komanso kukhala ndi malo okwanira kuti zitsimikizire kuti mpweya wotuluka umakhala wosalala. Pansi pa mzere wotulutsa valavu yothandizira pazikhala ndi mzere wamadzi kupita kumalo otetezeka. Mavavu sayenera kuikidwa mu chitoliro cha utsi kapena mutope woperekera. VALVE YACHITETEZO PA ECONOMIZER IDZAKHALA NDI PIPI YOTHA NDI KUTHAWIRA KU MALO OTETEZEKA. Palibe mavavu ADZAIKIKITSIDWA PA PIPI YA DRAIN.
