Ubhidwe ziintlobo zevalvu ezahlukeneyo? Ukukhetha engalunganga kunokuthetha ukuba kufuneka usike ivalve elunge ngokugqibeleleyo kumbhobho nje ukulungisa itywina elincinane, eligugileyo.
Ivalve yebhola eneziqwenga ezibini luyilo oluqhelekileyo lwevalvu eyenziwe kumacandelo amabini aphambili omzimba ajijwayo kunye. Olu lwakhiwo lubamba ibhola kwaye lutywine ngaphakathi, kodwa luvumela ukuba i-valve ikhutshwe ukuze ilungiswe ngokukhupha umzimba.
Esi sihloko sithe ngqo savela kwincoko noBudi, umphathi wokuthenga endisebenza naye eIndonesia. Wayenomthengi owayekhathazekile ngenxa yokuba ivalve kumgca wokunkcenkceshela obalulekileyo yaqalisa ukuvuza. Ivalve yayiyimodeli enexabiso eliphantsi, eneqhekeza elinye. Nangona ingxaki yayilitywina nje elincinane langaphakathi, babengenakwenza ngakumbi ngaphandle kokuvala yonke into, banqumle ivalve yonke kumbhobho, baze bancamathelise entsha. Kwajika ukusilela kwenxalenye yeedola ezintlanu kwaba ngumsebenzi wokulungisa wesiqingatha sosuku. Loo mava ambonisa ngoko nangoko ixabiso lehlabathi lokwenene aivalve elungisekayo, eyasikhokelela ngqo kwingxoxo malunga noyilo lwamacandelo amabini.
Uthini umahluko phakathi kweqhekeza eli-1 kunye neevalvu ezi-2 zebhola?
Ubona iivalve ezimbini ezikhangeleka ziyafana, kodwa enye ixabisa kancinci. Ukukhetha enexabiso eliphantsi kunokubonakala kububulumko, kodwa kunokukuxabisa kakhulu emsebenzini ukuba ithe yasilela.
Ivalve yebhola e-1 inomzimba omnye, oqinileyo kwaye iyalahlwa; ayinakuvulelwa ukulungiswa. AIvalve yesiqhekeza esi-2inomzimba othungelweyo ovumela ukuba kuhlulwe, ukuze ukwazi ukufaka indawo yangaphakathi njengezihlalo kunye netywina.
Umahluko ongundoqo kukusebenza. AIvalve yesiqhekeza esi-1yenziwe ngeqhekeza elinye lemathiriyeli. Ibhola kunye nezihlalo zilayishwa kwenye yeziphelo phambi kokuba uxhulumaniso lombhobho lwenziwe. Oku kuyenza ingabizi kakhulu kwaye yomelele, kwaye akukho zitywina zomzimba zokuvuza. Kodwa xa sele yakhiwe, itywinwa ngonaphakade. Ukuba isihlalo sangaphakathi siyaguga ngenxa yegrit okanye ukusetyenziswa, ivalve yonke yinkunkuma. AIvalve yesiqhekeza esi-2ixabisa ngaphezulu kancinci kuba inamanyathelo okuvelisa amaninzi. Umzimba wenziwe ngamacandelo amabini adibanisa kunye. Oku kusivumela ukuba siyidibanise nebhola kunye nezihlalo ngaphakathi. Okubaluleke ngakumbi, kukuvumela ukuba uyiqhawule kamva. Nasiphi na isicelo apho ukungaphumeleli kungabangela intloko ebuhlungu, ukukwazi ukulungisa i-valve ye-2-piece yenza kube yinto ephezulu yokukhetha ixesha elide.
I-1-Piece vs. 2-Piece at-a-Glance
| Uphawu | 1-Piece Ball Valve | 2-Piece Ball Valve |
|---|---|---|
| Ukwakhiwa | Umzimba omnye oqinileyo | Amacandelo amabini omzimba adityaniswe kunye |
| Ukulungiswa | Ayilungiseki (iyalahlwa) | Iyalungiseka (inokwahlulwa) |
| Iindleko zokuqala | Elona liphantsi | Phantsi ukuya Phakathi |
| Iindlela ezivuzayo | Indlela enye enokuvuza encinci (akukho tywina lomzimba) | Itywina elinye lomzimba ophambili |
| Ukusetyenziswa okuqhelekileyo | Iindleko eziphantsi, izicelo ezingabalulekanga | Injongo ngokubanzi, ishishini, ukunkcenkceshela |
Yintoni ivalve enamacandelo amabini?
Uyaliva igama elithi "ivalve yeziqwenga ezibini" kodwa ithetha ukuthini loo nto ngokwenyani? Ukungaqondi olu khetho loyilo olusisiseko kunokukhokelela ekuthengeni ivalve engafanelekanga kwiimfuno zakho.
Ivalve enamacandelo amabini yivalvu nje umzimba wayo owakhiwe ngamalungu amabini aphambili adityaniswe kunye, adla ngokudityaniswa ngentambo. Olu luyilo lubonelela ngolungelelwaniso olukhulu phakathi kweendleko zokwenziwa kwemveliso kunye nokukwazi ukunika inkonzo amalungu angaphakathi evalvu.
Yicinge njengomgangatho woshishino wevalve yebhola elungisekayo, yenjongo jikelele. Uyilo lulungelelaniso. Yazisa indlela enokuvuza enokuthi ivuze kwindawo apho amaqhekeza amabini omzimba adibanisa kunye, into enqandwa yivalve yesiqhekeza esi-1. Nangona kunjalo, eli lungu likhuselwe ngokutywinwa komzimba olomeleleyo kwaye lithembeke kakhulu. Inzuzo enkulu oku kuyidalayo kukufikelela. Ngokukhulula eli lungu, unokufika ngokuthe ngqo “kumathumbu” wevalve—ibhola kunye nezihlalo ezibini ezisazinge ezivale ngazo. Emva kokuba umthengi kaBudi efumene la mava aphazamisayo, wagqiba ekubeni abeke isitokhwe sethu se-2-piece valves. Uxelela abathengi bakhe ukuba ngexabiso elincinci elongezelelweyo langaphambili, bathenga ipolisi ye-inshorensi. Ukuba isihlalo sithe sahluleka, banokuthenga elulaikhithi yokulungisangeedola ezimbalwa kwaye ulungise ivalve, kunokuba uhlawule umtywini ukuze abuyisele yonke into.
Yintoni ivalve yeebhola ezimbini?
Ngaba ukhe waliva igama elithi "ivalve yebhola ezimbini"? Ukusebenzisa amagama angachanekanga kunokukhokelela ekubhidekeni kunye nokuyalela iindawo ezingafanelekanga, kubangele ukulibaziseka kweprojekthi kunye nokumosha imali.
"Ivalve yebhola ezimbini" ayilogama eliqhelekileyo loshishino kwaye lidla ngokulibiza kakubi elithi "iveluve yebhola enamacandelo amabini.” Kwiimeko ezikhethekileyo zokusetyenziswa, kunokuthetha ivalve yebhola ephindwe kabini, eyivalve ekhethekileyo eneebhola ezimbini ngaphakathi kumzimba omnye wokuvalwa kokhuseleko oluphezulu.
Oku kubhideka kuvela ngamanye amaxesha, kwaye kubalulekile ukucacisa. Amashumi alithoba anesithoba ekhulwini kwixesha, xa umntu ecela “ivalve yebhola ezimbini,” bathetha ngeiveluve yebhola enamacandelo amabini, ebhekisela kulwakhiwo lomzimba ebesixubusha ngalo. Nangona kunjalo, kukho imveliso engaphantsi kakhulu ebizwa ngokuba yi-aivalve yebhola ephindwe kabini. Lo ngumzimba omnye, omkhulu wevalvu oqulathe iindibano ezimbini ezahlukeneyo zebhola kunye nesihlalo ngaphakathi kuwo. Olu luyilo lusetyenziselwa izicelo ezibalulekileyo (kaninzi kwishishini leoli kunye negesi) apho ufuna "ibhloko ephindwe kabini kunye negazi." Oku kuthetha ukuba ungazivala zombini iivalvu kwaye emva koko uvule umsele omncinci phakathi kwazo ukuze uqinisekise ngokukhuselekileyo ukuvalwa okupheleleyo, okungqinwa kukuvuza okuli-100%. Kwizicelo eziqhelekileyo zePVC ezifana nemibhobho yamanzi kunye nokunkcenkceshela, awusoze udibane nevalve yebhola ephindwe kabini. Igama ekufuneka uyazi ligama elithi "iziqwenga ezibini."
Ukucoca isigama
| Ixesha | Oko Elikutshoyo Ngokwenene | Inani leeBhola | Ukusetyenziswa okuqhelekileyo |
|---|---|---|---|
| IValve yeBhola enamaqhekeza amabini | Ivalve enolwakhiwo lomzimba onamalungu amabini. | Nye | Injongo ngokubanzi yamanzi kunye nokuhamba kweekhemikhali. |
| Ivalve yeBhola ephindwe kabini | Ivalve enye eneendlela ezimbini zebhola zangaphakathi. | Mbini | Ukuvalwa kokhuseleko oluphezulu (umz., “ibhloko ephindwe kabini kunye nokopha”). |
Zeziphi ezi ntlobo zintathu zeevalvu zebhola?
Ufundile malunga nesiqwenga esi-1 kunye neevalvu ezi-2. Kodwa kuthekani ukuba ufuna ukulungisa ngaphandle kokuvala yonke inkqubo iiyure? Kukho uhlobo lwesithathu lwaloo nto kanye.
Iindidi ezintathu eziphambili zeevalve zebhola, ezihlelwe ngokwakhiwa komzimba, ziyi-1-piece, 2-piece, kunye ne-3-piece. Bamele isikali ukusuka kwixabiso eliphantsi kwaye akukho ukulungiswa (i-1-piece) ukuya kwiindleko eziphezulu kunye nenkonzo elula (3-piece).
Sizigubungele ezi zimbini zokuqala, ngoko ke masigqibezele umfanekiso ngodidi lwesithathu. AIvalve yebhola ye-3-pieceyeyona premium, uyilo olubonelelwa lula. Iqukethe icandelo lomzimba eliphakathi (elibambe ibhola kunye nezihlalo) kunye neengqungquthela ezimbini ezihlukeneyo ezidibeneyo kumbhobho. La macandelo mathathu abanjwe kunye ngeebholithi ezinde. Umlingo wolu yilo kukuba unokushiya ii-caps zokugqibela ezincanyathiselwe kumbhobho kwaye ngokulula unbolt umzimba oyintloko. Icandelo eliphakathi ke "lijingiwe," likunika ufikelelo olupheleleyo lokulungiswa ngaphandle kokusika umbhobho. Oku kubaluleke kakhulu kwiifektri okanye kwiindawo zorhwebo apho ixesha lokunciphisa inkqubo libiza kakhulu. Ivumela iulondolozo olukhawulezayo olunokwenzeka. UBudi ngoku unikezela ngeentlobo ezintathu kubathengi bakhe, ebakhokelela kukhetho olufanelekileyo olusekwe kuhlahlo lwabiwo-mali lwabo kunye nokuba kubaluleke kangakanani ukusetyenziswa kwabo.
Ukuthelekiswa kwe-1, i-2, kunye ne-3-Piece Ball Valves
| Uphawu | I-1-Piece Valve | I-Valve ye-2-Piece | I-Valve ye-3-Piece |
|---|---|---|---|
| Ukulungiswa | Akukho (Iyalahlwa) | Iyalungiseka (Kufuneka isuswe emgceni) | Igqwesile (Ilungiseka emgceni) |
| Iindleko | Phantsi | Phakathi | Phezulu |
| Engcono Kwi | Iimfuno eziphantsi, ezingabalulekanga | Injongo ngokubanzi, ibhalansi elungileyo yeendleko / iimpawu | Imigca yenkqubo ebalulekileyo, ukugcinwa rhoqo |
Ukuqukumbela
Aiveluve yebhola enamacandelo amabiniinikeza ukulungiswa ngokuba nomzimba okhululayo. Ngumhlaba ophakathi omangalisayo phakathi kweqhekeza eli-1 elilahlwayo kunye neemodeli zevalvu ezi-3 ezinokusetyenzwa ngokupheleleyo emgceni.
