Ivalizizinto ezibalulekileyo kwiinkqubo zokuphatha amanzi, zenza ukuba ulawulo kunye nommiselo wokuhamba kwamanzi. Ezimbini kwezona ntlobo zisetyenzisiweyo zeValves kwiZiko lemizi-mveliso, ezorhwebo, kunye nendawo yokuhlalaI-Palve yesangokwaye iJonga i-valve. Ngelixa zombini zisebenza kwindima ebalulekileyo kulawulo lwamanzi, uyilo, imisebenzi, nemisebenzi, kunye nokusetyenziswa kwahlukile. Ukuqonda umahluko phakathi kwezi ntlobo zimbini zeevalves kubalulekile ekukhetheni ivalve efanelekileyo yenkqubo ethile.
Esi sikhokelo sibanzi siza kuphonononga umahluko osisiseko phakathi kwe-valves yesango kunye neeVova, imigaqo-siseko yazo, uyilo, kunye neemfuno zolondolozo.
1. Ingcaciso kunye nenjongo
I-Palve yesango
I-valve yesango luhlobo lwe-valve esebenzisa isango elisecaleni okanye lomtshato) ukulawula ukuhamba kwamanzi ngombhobho. Intshukumo yesango, ehambelana nokuhamba, ivumela ukuvalwa ngokupheleleyo okanye ukuvulwa ngokupheleleyo kwindlela yokuhamba. I-valves yesango zihlala zisetyenziswa xa ukuhamba ngokupheleleyo, okungathandekiyo okanye ukuvalwa ngokupheleleyo kuyafuneka. Zilungele ukwenzela / ukucima ulawulo kodwa azilungelanga umgaqo-nkqubo webhola okanye ummiselo wokuhambahamba.
Jonga i-valve
Ivalve yokutshekisha, kwelinye icala, i-valve engabuyisi (NRV) Yenzelwe ukuvumela amanzi ukuba ahambe kwicala elinye kuphela. Eyona njongo yayo iphambili kukuthintela i-backflow, enokubangela ukonakala kwezixhobo okanye ukuphazamisa iinkqubo. Jonga iVovers isebenza ngokuzenzekelayo kwaye ayifuni ungenelelo lwemali. Ziqhelekile kwiinkqubo apho ukuhamba ngokubuyisela umva kunokubangela ungcoliseko, ukonakaliswa kwezixhobo, okanye inkqubo yokungasebenzi kakuhle.
2. Umgaqo wokuSebenza
Umgaqo wokuSebenza isango
Umgaqo wokusebenzela we-valve yesango ulula. Xa isiphatho se-valve okanye isivumelwano sijika, isango linyusa okanye liye ezantsi kwi-valve stem. Xa isango liphakama ngokupheleleyo, linika indlela engaphazanyiswa yokuhamba, kubangele uxinzelelo oluncinci. Xa isango lithotyelwe, libhlokheli ukuhamba ngokupheleleyo.
I-visves zesango Musa ukulawula amaxabiso okuhamba kakuhle, njengokuvula inxenye kunokukhokelela kwisiphithiphithi kunye nokudla, okukhokelela ekunxibeleleni nasekupheleni. Zisetyenziswa kakuhle kwizicelo ezifuna umsebenzi wokuqala wokugqibela / yokumisa kunokulawula ulawulo oluchanekileyo lokuhamba kwamanzi.
Jonga umgaqo wokuSebenzisa
I-velove yesheke isebenza ngokuzenzekelayo usebenzisa amandla olwelo. Xa ulwelo luhamba kwicala elicetywayo, lityhala i-disc, ibhola, okanye iflethi (kuxhomekeke kuyilo) kwindawo evulekileyo. Xa ukuhamba kokumaka okanye ukuzama ukubuyela umva, ivalve ivala ngokuzenzekelayo ngenxa yobuxoki, i-rectPrassing, okanye indlela yentwasahlobo.
Lo msebenzi ozenzekelayo uthintela ukubuyela umva, okuluncedo ngakumbi kwiinkqubo ezinempompo okanye iingcingo. Kuba akukho lulawulo lwangaphandle olufunekayo, jonga ii-valves zihlala zithathwa njenge "Doversive" valves.
I-3. Yila kunye nolwakhiwo
Uyilo lwe-valve yesango
Izinto eziphambili ze-valve yesango ibandakanya:
- Umzimba: Isikhephe sangaphandle esibambe zonke izinto zangaphakathi.
- I-Bonnet: Isigqubuthelo esisuswayo esivumela ukufikelela kwiindawo zangaphakathi zevalve.
- Isiqu: intambo yentambo eshukumisa isango ukuya ezantsi.
- Isango (i-disc): icandelo elifulethiweyo okanye elenziwe ngomtshato ezibhloka okanye ivumela ukuhamba.
- Isitulo: umphezulu apho isango lihlala lihlala khona xa livaliwe, liqinisekisa itywina eliqinileyo.
I-valve yesango inokuchazwa ukuba ihlelwe kwi-stem ye-stem kunye ne-strong stem. Ukunyuka kwe-valves kunika izikhombisi ezibonakalayo zokuba ivalve ivuliwe okanye ivaliwe, ngelixa uloyiso olungasebenziyo lukhethelwe apho indawo ethe nkqo inomda.
Jonga uyilo lweValve
Jonga i-valves yeza ngeendlela ezahlukeneyo, nganye inoyilo olwahlukileyo:
- I-swing wing valve: isebenzisa i-disc okanye i-flap eguqukayo kwi-hinge. Iyavula kwaye ivale ngokusekwe kwicala lokuhamba kwamanzi.
- Phakamisa i-Volve yeVenkile: I-disc inyukela phezulu kwaye ikhokelwe ngeposi. Xa ulwelo luhamba kwicala elifanelekileyo, idiski iphakanyisiwe, kwaye xa ukuhamba kuyayeka, i-disc ithothiwe ukutywina ivalve.
- I-Volve yokujonga ibhola: Sebenzisa ibhola ukuvimba indlela yokuhamba. Ibhola iqhubela phambili ukuvumela ukuphuma kukalwelo kwaye kubuye umva ukuze ibhloko yokubuyela umva.
- I-piston ye-piston ye-piston ye-piston ye-piston ye-piston ye-piston: ifana neVolve yokukhangela kodwa ngepiston endaweni ye-disc, ihambisa itywina elinzima.
- Uyilo lwevesi yokujonga ixhomekeke kwiimfuno ezithile zenkqubo, ezinje ngohlobo lolwelo, inqanaba lokuhamba, kunye noxinzelelo.
5. Izicelo
Izicelo zeSango
- Iinkqubo zokubonelela ngamanzi: Isetyenziselwa ukuqala okanye ukumisa ukuhamba kwamanzi kwimibhobho.
- Imibhobho yeoyile kunye negesi: Isetyenziselwa ukuzahlula kwemigca yenkqubo.
- Iinkqubo zonkcenkceshelo: Lawula ukuhamba kwamanzi kwizicelo zezolimo.
- Izityalo zamandla: Isetyenziswe kwiinkqubo ezithwele i-Steam, igesi, kunye nezinye izinto zobushushu obuphezulu.
Jonga izicelo zeVolve
- Iinkqubo zePump: Thintela ukubuyela umva xa impompo icinyiwe.
- Izityalo zonyango lwamanzi: Thintela ungcoliseko nge-backflow.
- Izityalo ezisebenzayo zemichiza: Thintela ukuxuba kweekhemikhali ngenxa yokubuyela umva.
- Iinkqubo ze-HVAC: Thintela ukubuyela umva kwee-fluids ezishushu okanye ezibandayo kwiinkqubo zokufudumeza kunye nokupholisa.
Ukuqukumbela
ZombiniI-valves yesangokwayeJonga i-valvevesDlala iindima eziyimfuneko kwiinkqubo ze-fluid kodwa ube nemisebenzi eyahlukileyo ngokupheleleyo. AI-Palve yesangoyivalve ye-bidirectial esetyenziselwa ukuqalisa okanye ukuyeka ukuhamba kwamanzi, ngelixaJonga i-valveyivalve engafunekiyo yokuthintela i-backflow. I-valve yesango zisebenza ngesandla okanye zisebenza ngokuzenzekelayo, ngelixa ukujonga iivallove isebenza ngokuzenzekelayo ngaphandle kokungenelela komsebenzisi.
Ukukhetha ivesi efanelekileyo kuxhomekeke kwiimfuno ezithile zenkqubo. Kwizicelo ezifuna ukuthintela ukubuyela umva, sebenzisa ivalve yokujonga. Kwizicelo apho kufuneka khona ulawulo lwamanzi, sebenzisa i-valve yesango. Ukukhetha ngokufanelekileyo, ufakelo, kunye nokulungiswa kwezi valve kuya kuqinisekisa ukusebenza kakuhle kwenkqubo, ukuthembeka, kunye nobomi obude.
