Uyabona kudweliswe "i-union valve" kunye ne "ball valve", kodwa ngaba zahlukile? Ukukhetha okungalunganga kuthetha ukuba kusenokufuneka usike i-valve elungileyo kamva ukuze ulungise ipompo.
Ivalvu yebhola ichaza indlela yokuvala (ibhola). I-union ichaza uhlobo loqhagamshelo oluvumela ukususwa (ii-union nuts). Azihlukani; ivalvu eguquguqukayo kakhulu yiivalvu yebhola yomanyano lokwenyani, edibanisa zombini ezi mpawu.
Le yenye yezona ngongoma zixhaphakileyo endizibonayo zokudideka, kwaye yinto ebalulekileyo kuye nawuphi na umsebenzi ochwephesha. Ndihlala ndixoxa ngale nto neqabane lam uBudi e-Indonesia, kuba abathengi bakhe bafuna izisombululo ezingasebenzi nje kuphela kodwa nezisebenzayo ukuze zigcinwe ixesha elide. Inyani yile, la magama achaza izinto ezimbini ezahlukeneyo: enye ikuxelela.Njaniivalvu iyasebenza, kwaye enye ikuxelelaindlela edibana ngayoukuya kumbhobho. Ukuqonda lo mahluko kubalulekile ekuyileni inkqubo ekrelekrele nelungisekayo.
Yintoni umahluko phakathi kwevalvu yebhola kunye nevalvu yebhola yomanyano?
Ufake ivalvu yebhola eqhelekileyo, uyincamathisele ngokusisigxina emgceni. Emva konyaka, isitywini siyasilela, uze uqonde ukuba ukhetho lwakho kuphela kukusika ivalvu yonke uze uqale phantsi.
Ivalvu yebhola eqhelekileyo yiyunithi enye, efakelwe ngokusisigxina. Ivalvu yebhola yomanyano lokwenyani inamantongomane anemisonto akuvumela ukuba ususe umzimba wevalvu ephakathi ngaphandle kokusika umbhobho, nto leyo eyenza ukulungiswa okanye ukutshintshwa kube lula.
Olu lolona mahluko lubalulekileyo ekucwangcisweni kwexesha elide. Cinga ngalo mahluko ngokuthi “ohlala ehleli” xa kuthelekiswa nokuthi “onokulungiseka.” Ivalvu yebhola eqhelekileyo, encinci idityaniswe ngqo kwipayipi. Nje ukuba ingenile, iyasebenza ngonaphakade. Oku kulungile kwimigca elula, engengomsebenzi ubalulekileyo.ivalvu yebhola yomanyano lokwenyaniNangona kunjalo, yenzelwe ixesha elizayo. Udibanisa iziqwenga zangasemva ezimbini ezahlukeneyo kumbhobho, kwaye umzimba wevalvu oyintloko uhlala phakathi kwazo. Ibanjwe endaweni yazo ziintonga ezimbini ezinkulu ze-union. Ukuba ufuna ukutshintsha izitywini zevalvu okanye umzimba wonke, ukhulula nje iinuts uze uziphakamise. Yingakho thina kwiPntek sixhasa uyilo lokwenyani lwe-union; iguqula ukulungiswa okukhulu kube ngumsebenzi olula wemizuzu emi-5.
I-Standard vs. True Union Ball Valve
| Uphawu | Ivalvu yeBhola eQhelekileyo (eNcinci) | I-True Union Ball Valve |
|---|---|---|
| Ufakelo | Isisigxina (esinyibilikisiweyo ngesinyibilikisi) | Ingalungiseka (iinuts zomanyano) |
| Ulondolozo | Kufuna ukusika umbhobho | Ukususwa komzimba ukuze kube lula ukulungiswa |
| Ixabiso lokuqala | Ezantsi | Phezulu |
| Ixabiso Lexesha Elide | Ephantsi (ukulungiswa okubizayo) | Phezulu (konga ixesha kunye nomsebenzi) |
Yintoni ivalvu yomanyano?
Ubona igama elithi “i-union valve” uze ucinge ukuba licandelo elahlukileyo ngokupheleleyo, njenge-gate valve okanye i-check valve. Oku kuthandabuza kunokukuthintela ekukhetheni ukhetho olusebenzayo.
Ivalvu yomanyano ayilohlobo lwendlela yokusebenza, kodwa luhlobo lonxibelelwano. Yiyo nayiphi na ivalvu esebenzisa izixhobo zomanyano (iinuts ezinemisonto) ukudibanisa umzimba wevalvu kwiziphelo zombhobho, nto leyo evumela ukuba isuswe lula.
"Umanyano" ngokwalo luyimveliso yobunjineli ebalaseleyo. Luneendawo ezintathu eziphambili: iziqwenga ezimbini zasemva ezidityaniswe nombhobho (nokuba nge-solvent weld okanye ngemisonto), kunye ne-nut enemisonto ezidibanisa kunye ukuze zenze isitywino.ivalvu yomanyano"Yakha nje olu phawu kuyilo lwevalvu. Ngoko ke, unokuba nevalvu yebhola ye-union eyiyo, ivalvu yokujonga i-union eyiyo, okanye ivalvu ye-union diaphragm eyiyo. Injongo isoloko ifana:ukusebenzisekaIkuvumela ukuba wahlukanise kwaye ususe isixhobo ngaphandle kokunciphisa uxinzelelo kwinkqubo yonke okanye, okubaluleke ngakumbi, ngaphandle kokusika umbhobho wakho. Le ndlela yokucwangcisa imibhobho sisiseko soyilo lwanamhlanje nolusebenzayo lwemibhobho kunye nenxalenye ephambili yefilosofi "yokunceda bonke" endibelana ngayo namaqabane anjengoBudi. Igcina abathengi bakhe ixesha nemali kulo lonke ixesha lenkqubo.
Ziziphi iintlobo ezintathu zeevalvu?
Ubusoloko usebenzisa iivalvu zebhola kuyo yonke into, kodwa isicelo esinye sifuna ulawulo oluchanekileyo lokuhamba kwamanzi. Uzama ukuvala ivalvu yebhola kancinci, kodwa kunzima ukuyilawula kwaye uva ingxolo engaqhelekanga.
Iintlobo ezintathu eziphambili zeevalvu ezisebenzayo zezi: Ukuvala (Ukuvula/Ukucima), Ukulawula (Ukulawula), kunye nokungabuyi (Ukuthintela Ukuhamba Kombane). Uhlobo ngalunye lwenzelwe umsebenzi owahlukileyo ngokupheleleyo, kwaye ukusebenzisa olungalunganga kunokonakalisa inkqubo yakho.
Ukwazi iindidi ezisisiseko kubalulekile ekukhetheni isixhobo esifanelekileyo somsebenzi. Ukusebenzisa ivalvu engalunganga yimpazamo eqhelekileyo. Ivalvu yebhola yiivalvu yokuvalaYenzelwe ukuba ivuleke ngokupheleleyo okanye ivalwe ngokupheleleyo. Ukuyisebenzisa ukujika kwe-throttle kunokubangela i-turbulence etshabalalisa ibhola kunye nezihlalo, nto leyo ebangela ukuba ingasebenzi.
Iindidi zeValve zichaziwe
| Uhlobo lweValve | Umsebenzi oPhambili | Imizekelo Eqhelekileyo | Eyona ndlela ilungileyo yokusebenzisa |
|---|---|---|---|
| Ukuvala (Vuliwe/Cinyiwe) | Ukumisa ngokupheleleyo okanye ukuvumela ukuhamba kwamanzi. | Ivalvu yeBhola, Ivalvu yeSango, Ivalvu yeButterfly | Ukwahlula iindawo okanye izixhobo. |
| Ukuqhobosha (Ukulawula) | Ukulawula isantya okanye uxinzelelo lokuhamba kwamanzi. | Ivalvu yeGlobe, iValvu yeNnaliti | Ukumisela isantya sokuhamba kwamanzi esichanekileyo. |
| Ukungabuyi (Ukubuyela umva) | Ukuvumela ukuhamba kwicala elinye kuphela. | Ivalvu Yokujonga, Ivalvu Yeenyawo | Ukukhusela ipompo ekuphumeni kwamanzi kwakhona. |
Ziziphi iintlobo ezine zeevalvu zebhola?
Uyazi ngeevalvu zokwenyani ze-union, kodwa ubona ezinye iindlela ezifana ne-"compact" okanye "one-piece." Awuqinisekanga ukuba yeyiphi efanelekileyo kwii-application ezahlukeneyo, kwaye usenokuba uhlawula kakhulu kwiimpawu ongazidingiyo.
Iintlobo ezine eziphambili zeevalvu zebhola zahlulwe ngokwakhiwa komzimba: Iqhekeza elinye (elitywiniweyo), Iqhekeza ezimbini (umzimba onemisonto), Iqhekeza ezintathu (njengomanyano lokwenyani), kunye neCompact (uyilo olulula nolungabizi kakhulu, oludla ngokuba yinxalenye enye).
Nangona indlela esebenza ngayo ngaphakathi ifana (ibhola ejikelezayo), indlela umzimba owakhiwe ngayo ilawula ixabiso kunye nokusebenza kwayo. Kwihlabathi le-PVC, sigxila kakhulu kuyilo lwe-union olunenxalenye enye/encinci kunye nolwe-three-piece/true.
- Ipisi enye /Ivalvu yeBhola eNcinci:Umzimba wevalvu yiyunithi enye, evaliweyo. Olu lolona yilo lungabizi kakhulu. Lukhaphukhaphu, lulula, kwaye lufanelekile usetyenziso apho ukugcinwa kungenangxaki kwaye iindleko ziphambili.
- Ivalvu yeBhola eneePiece ezimbini:Umzimba wenziwe ngeziqwenga ezibini ezidibanisa ibhola, zibambe ibhola kwaye zivale ngaphakathi. Oku kuvumela ukulungiswa okuthile kodwa kudla ngokufuna ukuyisusa emgceni. Ixhaphake kakhulu kwiivalvu zesinyithi.
- Iziqwenga Ezintathu (I-True Union) Ivalvu yeBhola:Olu luyilo oluphezulu. Luqulathe izihlanganisi ezimbini ezisekupheleni (iziqwenga zangasemva) kunye nomzimba ophakathi. Oku kuvumela ukuba umzimba oyintloko ususwe ukuze ulungiswe okanye utshintshwe ngaphandle kokuphazamisa umbhobho. Olu lolona khetho luthembekileyo nolungabizi kakhulu kwizicelo ezibalulekileyo kwixesha elide.
Apha ePntek, sigxile ekuboneleleni ngezona zinto zincinci nezingcono kakhuluiivalvu zomanyano lokwenyani, sinike amaqabane ethu afana neBudi iindlela ezifanelekileyo kuyo nayiphi na imfuno yabathengi.
Isiphelo
Ivalvu yebhola yindlela yokusebenza; i-union lunxibelelwano. Ivalvu yebhola ye-union yokwenyani iyadibanisa, inika ulawulo oluphezulu kunye nokugcinwa okulula kuyo nayiphi na inkqubo yobuchwephesha bokufaka amanzi.
