Udidekile ziintlobo ezahlukeneyo zeevalvu? Ukukhetha engalunganga kunokuthetha ukuba kufuneka usike ivalvu elungileyo kumbhobho ukuze ulungise isitywina esincinci nesigugileyo.
Ivalvu yebhola enamacandelo amabini luyilo oluqhelekileyo lwevalvu eyenziwe ngamacandelo amabini omzimba aphambili adibanisa iikrufu. Olu lwakhiwo lubamba ibhola kwaye luvale ngaphakathi, kodwa luvumela ivalvu ukuba ikhutshwe ukuze ilungiswe ngokukhulula umzimba.
Le ngongoma ivele ngqo kwincoko noBudi, umphathi wokuthenga endisebenza naye eIndonesia. Wayenomthengi owayekhathazekile kuba ivalvu ekwindawo yokunkcenkceshela ebalulekileyo yaqala ukuvuza. Ivalvu yayiluhlobo olungabizi kakhulu, olunento enye. Nangona ingxaki yayiluphawu oluncinci lwangaphakathi, babengenakukhetha ngaphandle kokuvala yonke into, banqumle ivalvu yonke kumbhobho, baze bancamathisele entsha. Yaguqula ukusilela kweenxalenye zeedola ezintlanu kwaba ngumsebenzi wokulungisa isiqingatha sosuku. Loo mava ambonise ngoko nangoko ixabiso lokwenyani le-ivalvu enokulungiswa, nto leyo eyasikhokelela ngqo kwingxoxo malunga noyilo oluneziqwenga ezibini.
Yintoni umahluko phakathi kwevalvu yebhola yeqhekeza eli-1 kunye neyeqhekeza eli-2?
Ubona iivalvu ezimbini ezibonakala zifana, kodwa enye ibiza kancinci. Ukukhetha eyona ingabizi kakhulu kunokubonakala kukuhle, kodwa kunokubiza imali eninzi kakhulu xa usebenza ukuba ayisebenzi.
Ivalvu yebhola yeqhekeza elinye inomzimba omnye, oqinileyo kwaye ingasetyenziswa xa isetyenziswa; ayinakuvulwa ukuze ilungiswe.ivalvu eneziqwenga ezibiniinomzimba onemisonto ovumela ukuba isuswe, ngoko ke ungatshintsha iindawo zangaphakathi ezifana nezihlalo kunye nezitywini.
Umahluko oyintloko kukuba iyasebenza na.ivalvu yeqhekeza eli-1yenziwe ngento enye eyenziwe ngesinyithi. Ibhola kunye nezihlalo zifakwa ngenye yeziphelo ngaphambi kokuba kwenziwe uqhagamshelo lombhobho. Oku kuyenza ingabizi kakhulu kwaye ibe namandla, kungekho zitywino zomzimba ezinokuvuza. Kodwa xa sele yakhiwe, ivalwa ngonaphakade. Ukuba isihlalo sangaphakathi siyaphela ngenxa yokungcola okanye ukusetyenziswa, ivalvu yonke iyaba yinkunkuma.ivalvu eneziqwenga ezibiniIxabisa kancinci kuba inezinyathelo ezininzi zokwenziwa. Umzimba wenziwe ngamacandelo amabini adibanisa. Oku kusenza sikwazi ukuwuhlanganisa nebhola size sihlale ngaphakathi. Okubaluleke ngakumbi, kukuvumela ukuba uwuqhawule kamva. Nakuphi na ukusetyenziswa apho ukusilela kunokubangela intloko ebuhlungu, ukukwazi ukulungisa ivalvu enamaqhekeza amabini kuyenza ibe lolona khetho lubalaseleyo lwexesha elide.
Isiqwenga esi-1 xa sithelekiswa nesiqwenga esi-2 ngokujonga nje
| Uphawu | Ivalvu yeBhola yeSiqwenga esi-1 | Ivalvu yeBhola yeZiqwenga ezi-2 |
|---|---|---|
| Ulwakhiwo | Umzimba omnye oqinileyo | Amacandelo amabini omzimba adityaniswe kunye |
| Ukulungiswa | Ayilungiseki (ayinakulahlwa) | Iyalungiswa (ingasuswa) |
| Ixabiso lokuqala | Eyona iphantsi | Ephantsi ukuya kwePhakathi |
| Iindlela zokuvuza | Indlela enye engaphantsi kokuvuza (akukho sitywino somzimba) | Isitywino esinye somzimba oyintloko |
| Ukusetyenziswa Okuqhelekileyo | Izicelo ezingabizi kakhulu nezingabalulekanga | Injongo ngokubanzi, imboni, ukunkcenkceshela |
Yintoni ivalvu enamacandelo amabini?
Uyaliva igama elithi “ivalvu enamacandelo amabini” kodwa oko kuthetha ukuthini ngokwenene? Ukungaluqondi olu khetho lusisiseko kunokubangela ukuba uthenge ivalvu engafanelekanga kwiimfuno zakho.
Ivalvu enamacandelo amabini yivalvu nje enomzimba owakhiwe ngamacandelo amabini aphambili adityaniswe kunye, ngesiqhelo ngoqhagamshelo olunemisonto. Olu yilo lubonelela ngolungelelwano olukhulu phakathi kweendleko zokuvelisa kunye nokukwazi ukulungisa iindawo zangaphakathi zevalvu.
Cinga ngayo njengomgangatho weshishini wevalvu yebhola elungisekayo, esetyenziswa ngokubanzi. Uyilo luyimvumelwano. Ingenisa indlela enokuvuza kwindawo apho iziqwenga ezibini zomzimba zidibana khona, into ephephekayo kwivalvu yeqhekeza eli-1. Nangona kunjalo, eli joyina likhuselwe sisitywina somzimba esiqinileyo kwaye lithembekile kakhulu. Inzuzo enkulu edalwa yile nto kukufikelela. Ngokukhulula eli joyina, ungafikelela ngqo "kwizibilini" zevalvu - ibhola kunye nezihlalo ezibini ezijikelezayo ezivala kuzo. Emva kokuba umthengi kaBudi efumene loo mava acaphukisayo, wagqiba ekubeni agcine iivalvu zethu zeqhekeza eli-2. Uxelela abathengi bakhe ukuba ngexabiso elincinci elongezelelweyo kwangaphambili, bathenga ipolisi yeinshurensi. Ukuba isihlalo sikhe siwe, banokuthenga elulaikhithi yokulungisangeedola ezimbalwa ndize ndilungise ivalvu, endaweni yokuhlawula umbhobho ukuze atshintshe yonke into.
Yintoni ivalvu yebhola ezimbini?
Ngaba wakha weva igama elithi “iivalvu ezimbini”? Ukusebenzisa amagama angachanekanga kunokubangela ukudideka kunye noku-odola iindawo ezingalunganga, okubangela ukulibaziseka kweprojekthi kunye nokuchitha imali.
Igama elithi “Two ball valve” alilogama eliqhelekileyo elisetyenziswa kushishino kwaye lidla ngokuba yindlela engafanelekanga yokubiza igama elithi “ivalvu yebhola enamacandelo amabini"Kwiimeko ezisetyenziswa ngokukodwa, kunokuthetha ivalvu yebhola ephindwe kabini, eyivalvu ekhethekileyo eneebhola ezimbini ngaphakathi komzimba omnye ukuze kucinywe ukhuseleko oluphezulu.
Oku kudideka kuvela ngamanye amaxesha, kwaye kubalulekile ukucacisa. Amashumi alithoba anesithoba ekhulwini exesha, xa umntu ecela "ivalvu yebhola ezimbini," uthetha ngeivalvu yebhola enamacandelo amabini, sibhekisa kulwakhiwo lomzimba ebesithetha ngawo. Nangona kunjalo, kukho imveliso engaqhelekanga kakhulu ebizwa ngokuba yiivalvu yebhola ephindwe kabini. Le yivalvu enye, enkulu enezixhobo ezimbini ezahlukeneyo zebhola kunye nezihlalo ngaphakathi kuyo. Olu yilo lusetyenziselwa izicelo ezibalulekileyo (ngokuqhelekileyo kwishishini leoyile negesi) apho ufuna "ibhloko ephindwe kabini kunye negazi." Oku kuthetha ukuba ungazivala zombini iivalvu uze uvule umsele omncinci phakathi kwazo ukuqinisekisa ngokukhuselekileyo ukuvalwa okupheleleyo, okungavumeli ukuvuza kwe-100%. Kwiizicelo zePVC eziqhelekileyo ezifana nemibhobho kunye nokunkcenkceshela, awusoze udibane nevalvu yebhola ephindwe kabini. Igama ekufuneka ulazi lithi "iziqwenga ezimbini."
Ukucacisa Amagama Asetyenzisiweyo
| Ixesha | Oko Kuthetha Ngokwenene | Inani leeBhola | Ukusetyenziswa Okuqhelekileyo |
|---|---|---|---|
| Ivalvu yeBhola eneePiece ezimbini | Ivalvu enomzimba onamacandelo amabini. | Nye | Ukuhamba kwamanzi kunye neekhemikhali ngokubanzi. |
| Ivalve yeBhola ephindwe kabini | Ivalvu enye eneendlela ezimbini zangaphakathi zebhola. | Mbini | Ukuvalwa kokhuseleko oluphezulu (umz., “ukuvimba kabini kunye nokuphuma kwegazi”). |
Ziziphi iintlobo ezintathu zeevalvu zebhola?
Ufundile ngeevalvu ezinesiqwenga esinye kunye nezineziqwenga ezimbini. Kodwa kuthekani ukuba kufuneka ulungise ngaphandle kokuvala yonke inkqubo kangangeeyure? Kukho uhlobo lwesithathu lwaloo nto kanye.
Iintlobo ezintathu eziphambili zeevalvu zebhola, ezahlulwe ngokwesakhiwo somzimba, zezine-piece enye, ezi-2, kunye nezi-3. Zimela isikali ukusuka kwixabiso eliphantsi kunye nokungalungiswa (i-piece e-1) ukuya kwixabiso eliphezulu kunye nokulungiseka okulula (izi-piece ezi-3).
Sizigubungele ezimbini zokuqala, ngoko ke masigqibezele umfanekiso ngohlobo lwesithathu.Ivalvu yebhola enamaqhekeza amathathuluyilo oluphezulu nolulula kakhulu ukulungiselelwa. Luqulathe icandelo lomzimba eliphakathi (elibamba ibhola kunye nezihlalo) kunye neentloko ezimbini ezahlukeneyo eziqhagamshelwe kumbhobho. La macandelo mathathu abanjwe kunye ngeebholiti ezinde. Umlingo wolu yilo kukuba ungashiya iintloko zokugqibela zinamathele kumbhobho uze ukhulule nje umzimba oyintloko. Icandelo eliphakathi emva koko "liyajika," likunika ukufikelela okupheleleyo kokulungiswa ngaphandle kokuyinqumla umbhobho. Oku kubaluleke kakhulu kwiifektri okanye kwiindawo zorhwebo apho ixesha lokungasebenzi kwenkqubo libiza kakhulu. Ivumelaulondolozo olukhawulezileyo olunokwenzekaNgoku uBudi unikezela zonke ezi ntlobo zintathu kubathengi bakhe, ebakhokela kukhetho olufanelekileyo ngokusekelwe kuhlahlo lwabiwo-mali lwabo kunye nokuba isicelo sabo sibaluleke kangakanani.
Ukuthelekiswa kweeValvu zeBhola ezi-1, 2, kunye nezi-3
| Uphawu | Ivalvu yeSiqwenga esi-1 | Ivalvu yeziqwenga ezi-2 | Ivalvu yeziqwenga ezi-3 |
|---|---|---|---|
| Ukulungiswa | Akukho nto (Engalahlwayo) | Iyalungiswa (Kufuneka isuswe kumgca) | Igqwesile (Ingalungiswa kwi-intanethi) |
| Ixabiso | Iphantsi | Phakathi | Phezulu |
| Eyona ilungileyo | Iimfuno ezingabizi kakhulu nezingengobalulekileyo | Injongo ngokubanzi, ibhalansi elungileyo yeendleko/iimpawu | Imigca yenkqubo ebalulekileyo, ukugcinwa rhoqo |
Isiphelo
Aivalvu yebhola enamacandelo amabiniInika ukulungiswa ngokuba nomzimba okhululayo. Libala eliphakathi elihle phakathi kwesixhobo esinye esilahlwayo kunye neemodeli zevalvu ezi-3 ezisebenza ngokupheleleyo.
