Iivalvu kumashishini ahlukeneyo kuluhlu olubanzi lwezicelo, ngakumbi kwipetroleum, i-petrochemical, ikhemikhali, isinyithi, amandla ombane, ukugcinwa kwamanzi, ukwakhiwa kwedolophu, umlilo, oomatshini, amalahle, ukutya kunye nezinye (apho, ishishini lomatshini kunye neekhemikhali. abasebenzisi bemarike yevalvu baxhalabile ngakumbi malunga neemfuno zevalvu nazo ziphezulu).
1, iivalve zofakelo lweoyile
Iyunithi yokucoca i-oyile. Uninzi lweevalvu ezifunekayo kwiiyunithi zokucoca i-oyile ziivalvu zemibhobho, ikakhuluivalve yesangos, iivalvu zeglowubhu, iivalvu zetshekhi, iivalvu zokhuseleko, iivalve zebhola, iivalve zebhabhathane, imigibe. Phakathi kwabo, i-valve yesango kufuneka iphendule malunga ne-80% yenani elipheleleyo leevalve, (ii-valve zibalwa kwi-3% ukuya kwi-5% yotyalo-mali olupheleleyo kwisixhobo).
2、Iivalvu zokusetyenziswa kweplanti yombane wombane
Ukwakhiwa kweplanti yamandla yaseTshayina kuyaphuhla kwicala lobukhulu obukhulu, ngoko ke imfuno yobukhulu obukhulu kunye neevalvu zokhuseleko loxinzelelo oluphezulu, iivalvu zokunciphisa uxinzelelo, iivalvu zeglowubhu, iivalvu zesango,I-RESILIENT butterfly valves,iivalvu zokuthintela okungxamisekileyo kunye neevalvu zolawulo lokuqukuqela, iivalve zeglowubhu zesixhobo sokutywina esingqukuva.
3、Iivalvu zesicelo seMetallurgical
Umzi-mveliso we-Metallurgical kwindlela yokuziphatha ye-alumina ifuneka ikakhulu ukunxitywa kwevalve eludaka (ekuhambeni kweevalvu zeglowubhu), ukulawula imigibe. Ushishino lokwenza intsimbi lufuna ikakhulu iivalvu zebhola ezitywinwe ngentsimbi, iivalvu zebhabhathane kunye neevalvu zebhola ze-oxidation, iflash cut-off kunye nee-four-way directional valves.
4, ivelufa yezicelo zaselwandle
Kulandelwa kuphuhliso lwemigodi ye-oyile ekude nonxweme, ubungakanani beenwele zayo ezisicaba zaselwandle ezifuna ukusebenzisa ivalvu ziye zanda kancinci kancinci. Iiplatifti zaselwandle kufuneka zisebenzise iivalve zebhola ezivaliweyo, iivalve zokujonga, iivalve zeendlela ezininzi.
5, isivalo sokutya kunye neyeza
Ushishino lufuna ikakhulu iivalvu zebhola zentsimbi estainless, iivalvu zebhola zeplastiki ezingenabungozi kunye neevalvu zebhabhathane. Ezi ndidi zingasentla zili-10 zeemveliso zevalvu, xa kuthelekiswa nesininzi semfuno yeevalvu zenjongo jikelele, ezinjengeevalvu zesixhobo, iivalvu zeenaliti, iivalvu zeglowubhu yenaliti, iivalvu zesango, iivalvu zeglowubhu,khangela ivalves, iivalve zebhola, iivalve zebhabhathane ubukhulu becala.
6, emaphandleni, iivalvu zokufudumeza ezidolophini
Inkqubo yokufudumala yeSixeko, kufuneka isebenzise inani elikhulu leevalve zebhabhathane ezitywinwe ngentsimbi, iivalve zokulinganisa ezithe tyaba kunye neevalvu zebhola ezingcwatywe ngokuthe ngqo. Ngenxa yolu hlobo lwevalve yokusombulula umbhobho welongitudinal kunye nokuphazamiseka kwe-hydraulic transverse, ukuphumeza ukonga amandla, ukuveliswa kobushushu obulungeleleneyo.
7, iivalvu zokufaka umbhobho
Imibhobho yomgama omde ikakhulu eye-oyile ekrwada, iimveliso ezigqityiweyo kunye nemibhobho yendalo. Olu hlobo lombhobho kufuneka lusebenzise uninzi lweevalvu ziyintsimbi yomxokozelo enemizimba emithathu egcweleyo, iivalvu zesango lepleyiti echasene nesalfure, iivalvu zokhuseleko, iivalvu zokukhangela.
