'Kwihlathi lentsimbi' lemibhobho yoshishino,iivalvesebenza njengabasebenzi bamanzi athuleyo, belawula ukuhamba kolwelo. Noko ke, ngokufuthi ‘bafa beselula,’ nto leyo elusizi ngokwenene. Ngaphandle kokuba yinxalenye yebhetshi efanayo, kutheni abanye besenzaiivalvebathathe umhlala-phantsi phambi kwexesha ngelixa abanye beqhubeka bekhonza? Namhlanje, masilandele ingcaphephe yokulawula ulwelo lwamanzi ukufumanisa inyani emva kobomi obufutshane beiivalve.
Oonobangela abathathu abakhuluivalve"ubomi obufutshane"
Ukufunxa ukuya ekufeni: uMzabalazo oBini woxinzelelo oluPhezulu kunye nokuRhakala kweMpembelelo yoxinzelelo oluPhezulu: Xa uxinzelelo lwenkqubo lugqithise kakhulu imida yoyilo lwevalvu,ivalveumzimba kunye netywina ziphantsi koxinzelelo olukhulu, olukhokelela kuguquko lwesakhiwo kunye nokusilela kwetywina. Iimpembelelo zehamile zamanzi ngoko nangoko zifana nokwenzakala kwangaphakathi, okukwaziyo ukwenza ivalve ngoko nangoko ingasebenzi. I-Corrosion Devoring: Kwiimeko ezirhabaxa ezifana neekhemikhali kunye nemekobume yamanzi olwandle, imidiya ebolileyo isebenza njengeentende zezandla ezithambisa amathambo, ikhukulisa ngokuthe cwaka ukutyeba kodonga lomzimba wevalvu (ngesantya sokutya esingaphaya kwe-0.5 mm/ngonyaka), yenza buthathaka amandla ayo, kwaye ibangele ukugqobhoza nokuvuza. Amanzi ayaqonda ukuba imathiriyeli ibalulekile, kwaye iivalvu zayo ezikhethekileyo (ezifana neHastelloy kunye ne-duplex steel) zifana nekhaka lentsimbi yegolide, 'eluphucula ngokubonakalayo uxinzelelo lwazo kunye nokumelana nomhlwa. Ukunxiba ngokugqithisileyo: Ukusika okukhohlakeleyo ngokuKhukula kweMedia ye-High-Speed Fluids: Amasuntswana aqinileyo (afana ne-mineral slurry kunye nomlotha) okanye i-high-speed fluids (njenge-steam kunye namanzi e-cavitation) ngokuqhubekayo ahlambulule indawo yokutywina kunye negumbi le-valve, esebenza njengeemela ezingenakubalwa ze-micro-engraving. Ngokuhamba kwexesha, ezi zenzo zenza igrooves enzulu kumphezulu wokutywina, okukhokelela ekungaphumeleli kokutywinwa. Imiphezulu yealloyi yokutywina enobulukhuni obuphezulu bamanzi (efana netungsten carbide kunye ne-STL) kunye noyilo lwendlela yokuhamba ephuculweyo isebenza 'njengehempe zentsimbi' ngokuchasene 'nokusikwa kwewaka.'
Ukuvaleka kweAsphyxiation blockage: Ukuvaleka okuyingozi kobumdaka kunye nesikali
Ukungena kobumdaka: I-weld slag, irusi, kunye nezinto zangaphandle zinokungena kumbhobho kwaye zibambeke phakathi kwesitulo sevalve kunye nombindi. Oku kunokubangela ukuba ivalve ingaphumeleli ukuvala okanye ukuvula ngokufanelekileyo, kwaye kwiimeko ezinzima, zonakalise indawo yokutywina echanekileyo. Icrystallization ephakathi kunye nokukala: Kwiimeko ezithile (ezifana namanzi okupholisa okanye uludaka), indawo ephakathi inokucwebezela okanye isikali ngaphakathi.ivalve, ukutshixa ngokufanelekileyo i-valve joints, ekhokelela ekuvinjeni okuvila okanye okupheleleyo. Amanzi 'uyilo lokulwa nokuvala, olufana ne-V-type yebhola ye-V kunye nezakhiwo ze-scraper, zisebenza njengezixhobo ezisebenzayo zokucoca ezi' zihlunu zegazi.'
"Impazamo" yomsebenzisi ikhawulezise ubomi bevalvu
Ngoku kaIvalve ye-TWS yotywino lwamanzi, ixesha elide levalvu ayisiyongozi, kodwa ubunjineli benkqubo ukusuka kuyilo, ukukhetha izinto, ukwenziwa kunye nokusetyenziswa:
Ukuhambelana okuchanekileyo, okulungiselelwe ngokuKhethekileyo: Yenza uhlalutyo olucokisekileyo lweemeko zokusebenza (uxinzelelo, ubushushu, i-medium, i-particle content, kunye ne-frequency yokusebenza) ukukhetha uhlobo olufanelekileyo lwevalve (ivalve yesango, ivalve yeglowubhu, ivalve yebhola,ivelufa butterfly) kunye nezinto eziphathekayo. Amacandelo Angundoqo, Ukuzabalazela ukugqibelela: Isibini sokutywinwa senziwe kwi-alloy eqinile engagugiyo kunye ne-corrosion; isiqu sevalvu senziwe ngezinto ezinokumelana nomhlwa ezinokuqina okuphezulu kunye nonyango lomphezulu olwandisiweyo; Amacandelo abalulekileyo anoxinzelelo aqinisekiswa ngokungqongqo ngokuhlalutya izinto ezinqamlekileyo (FEA). Ubuchwephesha, ukulawulwa komgangatho ongqongqo: Ukuchaneka komatshini kuqinisekisa ukunyamezela okuchanekileyo, kunye novavanyo olungqongqo olungonakalisi (RT / UT / PT) lususa iziphene zangaphakathi; yonke inkqubo kukuzibophelela ekuthembekeni. Ukukhetha okuhlakaniphileyo, ukulindela ikamva: Ukunikezela ngesikhokelo sokhetho lobuchwephesha kunye nezisombululo ezilungiselelwe ukuqinisekisa ukuba iivalve 'zizalwa ngexesha elifanelekileyo, kwindawo efanelekileyo.'
Phatha yonke "intliziyo yeshishini" kakuhle
Ukungaphumeleli kwangaphambili kweevalvu luphawu lwesilumkiso semiba enokwenzeka yenkqubo kwaye kubonisa ilahleko yezibonelelo kunye nokusebenza kakuhle. Ngokukhetha Amanzi, ukhetha ubungcali kunye nokuzinikela ukufaka iinkqubo zakho zolwelo ngamandla ahlala ehleli. Asiboneleli nje ngeemveliso zevalvu ezihlala ixesha elide kodwa sikwakhuthaza imigaqo yolawulo lwenzululwazi kunye nokusebenza okusemgangathweni. Kuphela kungokuqonda, ukuhlonipha, kunye nokuphatha aba 'bagcini bamashishini' bathuleyo banokuthi basebenze ngokuzinzileyo, ngokufanelekileyo nangexesha elide kwiindima zabo, ngokudibeneyo beqinisekisa ukuhamba kakuhle kweenkqubo zemizi-mveliso!
