isicelo

Phantse yonke imibhobho ecingelwayo okanye izicelo zothutho lwamanzi, nokuba kushishino, kwezorhwebo okanye kwasekhaya, ukusetyenziswakhangela iivalvu.Ziyinxalenye ebalulekileyo yobomi bemihla ngemihla, nangona zingabonakali.Ugutyulo, unyango lwamanzi, unyango lwezonyango, ukusetyenzwa kweekhemikhali, ukuveliswa kwamandla, ikhemesti, i-chromatography, ezolimo, i-hydropower, i-petrochemical kunye nokutya kunye nokusela utywala amashishini asebenzisa ii-valve zokutshekisha kwimisebenzi yabo yemihla ngemihla ukukhusela ngokufanelekileyo ukubuyisela umva.Ngenxa yokuba zithintela ukusilela kwemveliso kwaye azifuni kulawulwa ngexesha lokusebenza, i-valve yokukhangela ayinqweneleki kuphela, kodwa ngokuqhelekileyo ifunwa ngumthetho ukuqinisekisa ukhuseleko lwamanzi, igesi, kunye nezicelo zoxinzelelo.

Ekhaya, bancedisa ukuqala kunye nokumisa ukuhamba kwamanzi.Zisetyenziswa kwizifudumezi zamanzi, kwimibhobho yangaphakathi, iitephu kunye nezixhobo zokuhlamba izitya, kunye nezixhobo eziphucuke ngakumbi ezifana neempompo zokulinganisa iimitha, izixube, izixube kunye neemitha zokuhamba.Iinkqubo zokujonga iivalvu zemizi-mveliso kwinyukliya, kwifektri, kwiplanti yeekhemikhali, kwiinkqubo ze-hydraulic zeenqwelomoya (ubushushu bokungcangcazela kunye nezinto ezidliwayo), iziphekepheke kunye neenkqubo zokuqalisa isithuthi (ulawulo lokusabela, ukulawulwa kwepropellant, ulawulo lokuphakama), kunye neenkqubo zolawulo lokuhamba komoya (ukuthintela ukuxubana kwegesi )

Iimbonakalo

Iivalvu zokujonga ziya zithandwa ngakumbi ngenxa yoyilo lwazo olulula kunye nokusebenziseka ngokulula.Inkqubo ilula kakhulu.Njengoko kukhankanyiwe ngaphambili, ukusebenza kwevalve yokukhangela kugqitywe ngokupheleleyo yinkqubo yokuhamba, oku kuthetha ukuba akukho mfuneko yokongeza i-actuator.Ngokuqhelekileyo, i-valve isebenza njengesixhobo se-cylindrical esixhunywe kwintloko yepompo kwi-inlet kunye nemigca yokuphuma.Isixhobo esisebenzayo esinezivulo kuzo zombini iziphelo sinqumla iqokobhe kwaye sahlule iqokobhe kwiindawo ezinyukayo nezisezantsi.Isihlalo sevalve sisuka eludongeni lwesilinda, kodwa sinendawo yokuvula ilungele ukuhamba kwenkqubo.

Ibhola, ikhowuni, idiskhi okanye esinye isixhobo sobukhulu obugqithileyo sixhomekeke kwisitulo sevalve kwicala elisezantsi levalve yokujonga.Ukushukuma okulinganiselweyo kuthintela isixhobo sokuplaga ekubeni sigungxulelwe ezantsi.Xa i-fluid ihamba ngendlela echazwe kwangaphambili phantsi koxinzelelo oluyimfuneko, iplagi iyasuswa kwisihlalo sevalve kwaye i-fluid okanye igesi ivumelekile ukuba idlule kwi-gap ephumela.Njengoko uxinzelelo lwehla, iplagi ibuyela kwisihlalo ukukhusela umva.

I-Gravity okanye i-stainless steel stainless spring loading mechanisms ngokuqhelekileyo inoxanduva lwale ntshukumo yokubuya, kodwa kwezinye iimeko, uxinzelelo olongezelelweyo kwicala elisezantsi le-valve lanele ukuhambisa isixhobo sibuyele kwindawo yaso yokuqala.Ukuvalwa kwe-valve kuthintela izinto ezisezantsi ekuxubeni kunye nezinto ezinyukayo nangona uxinzelelo lukhula.Iiplagi ezithile ezisetyenzisiweyo ziyahluka ngokuxhomekeke kuhlobo lwevalve yokukhangela efakiweyo.Njengoko igama lisitsho,kusetyenziswa iivalvu zokujonga ibholaiibhola.Iivalvu zetshekhi zokuphakamisa zisebenzisa iicones okanye iidiski ezincanyathiselwe kwizikhokelo zeentonga ukuqinisekisa ukuba zibuyela kwindawo eyiyo kwisitulo sevalve.I-Swing kunye ne-wafer valves zisebenzisa idiski enye okanye ngaphezulu ukuvala isithuba esihlalweni.

Izinto ezilungileyo zevalve yokukhangela

Iivalvu zokujonga zineenzuzo ezininzi.Okokuqala, banokulawula ukuhamba kwe-psi kumacandelo ahlukeneyo amashishini.Enyanisweni, banokusebenza kwi-psi ephezulu ngokwaneleyo yokucima umlilo, kwaye uxinzelelo lwe-psi lulawulwa ngokwaneleyo ukuba lusebenze kwi-scuba cylinder.Enye inzuzo yeevalvu zokutshekisha kukuba zithintela ukungcoliseka komnqamlezo wolwelo, kubandakanywa namanzi amatsha.
