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

/
Chidule: kusanthula kutayikira kwa valve yachitetezo cha boiler, kutayikira kwapamadzi, kutayikira kwapamadzi, valavu yoteteza chitetezo pambuyo poti valavu yopumirayo sichitapo kanthu, mpando wachitetezo wokhazikika womwe umasiyidwa mu valavu yopumira kuchedwa kubwerera pampando kwa nthawi yayitali komanso kutsika kwachitetezo kumbuyo. valavu, kulumpha pafupipafupi ndi flutter ndi zina zomwe zimayambitsa zolakwika, ndikuyika njira yothetsera vutolo.
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 yotentha ya boiler yamadzi otentha ndi yaikulu kuposa 1.4MW, osachepera 2 ma valve otetezera adzaikidwa; 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 yotetezera kulemera kwamadzi 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 omwe ali ndi mphamvu ya nthunzi yoposa 3.82Mpa, kutalika kwa mmero kwa valve yopumula 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 wopita 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 ma valve omwe ADZAIKIKITSIDWA PA PIPI YA DRAIN.
