Ubona “ivalve yomanyano” kunye “nevalve yebhola” zidweliswe, kodwa ngaba zahlukile? Ukukhetha okungalunganga kuthetha ukuba kuya kufuneka unqumle ivalve elunge ngokugqibeleleyo kamva ukuze ulungise impompo.
Ivalve yebhola ichaza indlela yokuvala (ibhola). Umanyano luchaza uhlobo loqhagamshelwano oluvumela ukususwa (amandongomane emanyano). Abahlukanga; eyona valve iguquguqukayo yiivelufa yebhola yomanyano lokwenene, edibanisa zombini iimpawu.
Le yenye yezona ngongoma zixhaphakileyo zokubhideka endizibonayo, kwaye ngumahluko obalulekileyo kuyo nayiphi na ingcali. Ndihlala ndixoxa ngale nto kunye neqabane lam uBudi e-Indonesia, kuba abathengi bakhe bafuna izisombululo ezingasebenziyo kuphela kodwa ezisebenzayo ukugcina ixesha elide. Inyaniso kukuba, la magama achaza izinto ezimbini ezahlukeneyo: enye iyakuxelelaNjaniivalve isebenza, kwaye enye iyakuxelelaidibana njanikumbhobho. Ukuqonda lo mahluko ngundoqo ekuyileni inkqubo ehlakaniphile, enokusetyenzwa.
Uthini umahluko phakathi kwevalve yebhola kunye nevalve yebhola yomanyano?
Ufake ivalve yebhola esemgangathweni, uyincamathelise ngokusisigxina emgceni. Emva konyaka, itywina liyasilela, kwaye uyaqonda ukuba ekuphela kwento onokuyikhetha kukusika ivalve yonke kwaye uqale phantsi.
Ivalve yebhola esemgangathweni yiyunithi enye, efakwe ngokusisigxina. Ivalve yebhola yomanyano yokwenyani inemisonto yamandongomane ekuvumela ukuba ususe umzimba wevalvu ephakathi ngaphandle kokusika umbhobho, ukwenza ugcino okanye ukutshintshwa kube lula.
Lo ngowona mahluko ubalulekileyo kucwangciso lwexesha elide. Yicinge ngokwegama elithi "isigxina" xa kuthelekiswa "nokusebenziseka." Ivalve esemgangathweni, edityanisiweyo yebhola i-solvent-welded ngqo kumbhobho. Xa sele ingenile, ingena ngokulungileyo. Oku kulungile kwimigca elula, engabalulekanga. Aivelufa yebhola yomanyano lokweneneNoko ke, yenzelwe ikamva. I-solvent-weld i-tailpieces ezimbini ezihlukeneyo kumbhobho, kunye nomzimba wevalve engundoqo uhlala phakathi kwawo. Ibanjelwe endaweni ngamandongomane amakhulu omanyano. Ukuba ufuna ukutshintsha izitywina zevalve okanye umzimba wonke, uvele ukhulule amantongomane kwaye uyiphakamise. Yiyo loo nto thina ePntek silwela uyilo lomanyano lokwenyani; ijika ulungiso olukhulu lube ngumsebenzi olula wemizuzu emi-5.
Umgangatho vs. True Union Ball Valve
| Uphawu | IValve yeBhola esemgangathweni (eQinisekileyo). | True Union Ball Valve |
|---|---|---|
| Ukuhlohla | Isigxina (i-solvent-welded) | Iyasebenziseka (amandongomane emanyano) |
| Isondlo | Ifuna ukusika umbhobho | Umzimba ususa ukulungiswa lula |
| Iindleko zokuqala | Ngasezantsi | Phezulu |
| Ixabiso lexesha elide | Ngaphantsi (ulungiso oluxabisa kakhulu) | Ephakamileyo (igcina ixesha kunye nomsebenzi) |
Yintoni ivalve yomanyano?
Ubona igama elithi “ivalve yomanyano” kwaye ucinga ukuba luhlobo olwahluke ngokupheleleyo, njengevalve yesango okanye ivalve yokukhangela. Oku kuthandabuza kunokukugcina ekukhetheni olona khetho lusebenzayo.
Ivalve yomanyano ayilohlobo lomatshini, kodwa luhlobo lonxibelelwano. Yiyo nayiphi na ivalve esebenzisa i-union fittings (i-threaded nuts) ukudibanisa umzimba wevalve kwiziphelo zombhobho, okuvumela ukususwa lula.
"Inyunyana" ngokwayo yinto eqaqambileyo yobunjineli. Iqukethe amacandelo amathathu aphambili: i-tailpieces ezimbini ezidibanisa kumbhobho (mhlawumbi nge-solvent weld okanye i-threads), kunye ne-nut eline-threaded ezidibanisa ukuze zenze itywina. A “ivelufa yomanyano” yakha nje olu phawu kuyilo lwevalvu Ke, unokuba nevalve yebhola yomanyano yokwenene, ivalve yokukhangela umanyano lokwenene, okanye ivalve yomanyano yediaphragm yokwenyani. Injongo isoloko ifana:inkonzo. Ikuvumela ukuba uhlukanise kwaye ususe isiqwenga sesixhobo ngaphandle koxinzelelo lwenkqubo yonke okanye, ngokubaluleke ngakumbi, ngaphandle kokusika umbhobho wakho. Le ndlela yemodyuli isisiseko soyilo lwangoku, olusebenzayo lwemibhobho kunye nenxalenye engundoqo yefilosofi ethi "win-win" endibelana ngayo namaqabane afana noBudi. Igcina abathengi bakhe ixesha kunye nemali kubomi benkqubo.
Zeziphi ezi ntlobo zintathu zeevalvu?
Ubusebenzisa iivalvu zebhola kuyo yonke into, kodwa isicelo esinye sidinga ulawulo lokuhamba oluchanekileyo. Uzama ukuvala ivalve yebhola, kodwa kunzima ukuyilawula kwaye uve ingxolo engaqhelekanga.
Iindidi ezintathu eziphambili ezisebenzayo zevalve yi-Shut-Off (On / Off), i-Throttling (Ukulawula), kunye ne-Non-Return (I-Backflow Prevention). Uhlobo ngalunye lwenzelwe umsebenzi owahluke ngokupheleleyo, kwaye ukusebenzisa ongalunganga kunokonakalisa inkqubo yakho.
Ukwazi iindidi ezisisiseko kubalulekile ekukhetheni isixhobo esifanelekileyo somsebenzi. Ukusebenzisa ivalve engalunganga yimpazamo eqhelekileyo. Ivalve yebhola yi aivalve yokuvala; yenzelwe ukuba ivuleke ngokupheleleyo okanye ivalwe ngokupheleleyo. Ukuyisebenzisela ukuququzela kunokubangela isiphithiphithi esikhukulisa ibhola kunye nezihlalo, kubangele ukuba ingaphumeleli.
Iindidi zeValve zicacisiwe
| Uhlobo lweValve | Umsebenzi oPhambili | Imizekelo eqhelekileyo | Eyona meko yokusetyenziswa |
|---|---|---|---|
| Vala (Valiwe/Valiwe) | Ukumisa ngokupheleleyo okanye ukuvumela ukuhamba. | Ivalve yeBhola, iValve yeSango, iValve yeButterfly | Ukwahlula amacandelo okanye izixhobo. |
| Ukuginya (Ukulawula) | Ukulawula isantya okanye uxinzelelo lokuhamba. | Ivalve yeglowubhu, iValve yenaliti | Ukumisela umyinge wokuqukuqela ochanekileyo. |
| Ukungabuyi (Backflow) | Ukuvumela ukuhamba kwicala elinye kuphela. | Jonga iValve, iValve yeenyawo | Ukukhusela impompo ekuphumeni ngasemva. |
Zeziphi ezi 4 iindidi zeevalvu zebhola?
Uyazi malunga neevalvu zomanyano lokwenyani, kodwa ubona ezinye iindlela ezinje nge "compact" okanye "isiqwenga esinye." Awuqinisekanga ukuba yeyiphi eyona ilungileyo kwizicelo ezahlukeneyo, kwaye unokuba uhlawula kakhulu ngeempawu ongazidingiyo.
Iindidi ezine eziphambili zeevalve zebhola zihlukaniswa ngokwakhiwa komzimba: I-Piece enye (itywinwe), i-Two-Piece (umzimba onomsonto), i-Three-Piece (njengomanyano lokwenyaniso), kunye ne-Compact (uyilo olulula, olunoqoqosho, ngokuphindaphindiweyo iqhekeza elinye).
Ngelixa indlela yangaphakathi iyafana (ibhola ejikelezayo), indlela owakhiwe ngayo umzimba ichaza iindleko zayo kunye nokusebenza kwayo. Ehlabathini le-PVC, sigxininise ngokukodwa kwi-piece-piece / compact kunye ne-piece-piece / yenyani yoyilo lomanyano.
- Ipisi enye /IValve yeBhola eyiCompact:Umzimba wevalvu yiyunithi enye, etywiniweyo. Olu lolona yilo loqoqosho. Ikhaphukhaphu, ilula, kwaye ifanelekile kwizicelo apho ukugcinwa kungenaxhala kwaye iindleko zingoyena mqhubi.
- IValve yeBhola enamaqhekeza amabini:Umzimba wenziwe ngeziqwenga ezibini ezijijwayo, zibambe ibhola kwaye zitywine ngaphakathi. Oku kuvumela ukulungiswa okuthile kodwa kaninzi kufuna ukuyisusa kumgca. Ixhaphake kakhulu kwiivalvu zentsimbi.
- Amaqhekeza amathathu (IManyano yoNyaniso) iValve yeBhola:Olu luyilo lweprimiyamu. Iqulathe izihlanganisi ezibini ekupheleni (tailpieces) kunye nomzimba osembindini. Oku kuvumela ukuba umzimba oyintloko ususwe ukulungiswa okanye ukutshintshwa ngaphandle kokuphazamisa umbhobho. Olu lolona khetho luthembekileyo nolunexabiso eliphezulu kwizicelo ezibalulekileyo kwixesha elide.
E-Pntek, sigxile ekuboneleleni ngeyona compact ingcono kwayeiivalvu zomanyano lokwenyani, Ukunika amaqabane ethu afana noBudi ukhetho olufanelekileyo kuyo nayiphi na imfuno yomthengi.
Ukuqukumbela
Ivalve yebhola yindlela; umanyano ludibaniso. Ivalve yebhola yomanyano yokwenyani iyabadibanisa, inikezela ngolawulo oluphezulu kunye nokugcinwa lula kuyo nayiphi na inkqubo yemibhobho yobungcali.
