Kufuneka uthenge iivalvu zebhola, kodwa jonga ukhetho "lwesiqwenga esinye" kunye nolwesiqwenga esinye. Khetha olungalunganga, kwaye ungajongana nokuvuza okukhathazayo okanye kufuneke usike ivalvu ebinokulungiswa.

Umahluko ophambili yindlela ezakhiwe ngayo.Ivalvu yebhola enesiqwenga esinyeinomzimba omnye, oqinileyo kwaye ayinakuhlulwa ukuze ilungiswe.Ivalvu yebhola enamaqhekeza amabiniyenziwe ngamacandelo amabini ahlukeneyo, nto leyo evumela ukuba idityaniswe ukuze kulungiswe izinto zangaphakathi.

Le yinkcukacha endihlala ndiyihlola namaqabane am afana noBudi eIndonesia. Kumphathi wokuthenga, ukuqonda lo mahluko kubalulekile. Ichaphazela ngokuthe ngqo iindleko zeprojekthi, ukugcinwa kwexesha elide, kunye nokwaneliseka kwabathengi. Ingabonakala ngathi yinkcukacha encinci, kodwa ukukhetha ngokuchanekileyo yindlela elula yokubonelela ngexabiso elikhulu kubathengi bakhe, ukusuka kubakhi abancinci ukuya kubathengi abakhulu bemizi-mveliso. Olu lwazi lubalulekile kwintsebenziswano ephumelelayo phakathi kwabo bonke.

Yintoni umahluko phakathi kwevalvu yebhola yeqhekeza eli-1 kunye neyeqhekeza eli-2?

Uzama ukukhetha ivalvu engabizi kakhulu. Ngaphandle kokuqonda umahluko woyilo, ungakhetha ivalvu engabizi kakhulu eya kubiza kakhulu ekuhambeni kwexesha ngexesha lokungasebenzi kunye nomsebenzi wokutshintsha.

Ivalvu eneqhekeza elinye yiyunithi evaliweyo nelahlwayo. Ivalvu eneqhekeza ezimbini ibiza kancinci kodwa iyinto enokulungiswa, ehlala ixesha elide. Ukhetho luxhomekeke ekulinganiseni iindleko zokuqala kunye nesidingo sokugcinwa kwixesha elizayo.

Ukuze sincede uBudi kunye neqela lakhe benze izindululo ezilungileyo, sisoloko sisebenzisa itheyibhile elula yokuthelekisa. Oku kwahlukanisa umahluko osebenzayo ukuze abathengi bakhe babone kanye into abayihlawulelayo. Ukhetho "oluchanekileyo" luhlala luxhomekeke kwiimfuno ezithile zomsebenzi. Kumgca ophambili oxinezelekileyo, ukulungiswa kubalulekile. Kumgca wokunkcenkceshela wexeshana, ivalvu elahlwayo inokuba yinto efanelekileyo. Injongo yethu ePntek kukunika amandla amaqabane ethu ngolu lwazi ukuze bakwazi ukukhokela abathengi babo ngokufanelekileyo. Le theyibhile ingezantsi sisixhobo endihlala ndisabelana ngaso noBudi ukuze ndicacise oku.

Ukuqonda le tshathi yeyona nyathelo libalulekileyo ekukhetheni ngokuchanekileyo.

Yintoni umahluko phakathi kwevalvu yebhola yenxalenye 1 kunye nenxalenye 2?

Uva umthengi ecela ivalvu ethi “inxalenye 1” okanye “inxalenye 2”. Ukusebenzisa amagama angachanekanga anje kunokukhokelela ekudidekeni, kwiimpazamo zoku-odola, kunye nokubonelela ngemveliso engafanelekanga kumsebenzi obalulekileyo.

“Icandelo 1” kunye “neCandelo 2” azingomagama aqhelekileyo kushishino. Amagama achanekileyo ngala “icandelo elinye” kunye “necandelo ezimbini.” Ukusebenzisa isigama esifanelekileyo kubalulekile kunxibelelwano olucacileyo kunye nokulandelelana ngokuchanekileyo kwikhonkco lokubonelela.

Ndisoloko ndigxininisa ukubaluleka kolwimi oluchanekileyo kuBudi kunye neqela lakhe lokuthenga. Kurhwebo lwehlabathi, ukucaca yeyona nto ibalulekileyo. Ukungaqondani okuncinci kwisigama kunokukhokelela ekubeni kufike imveliso engafanelekanga, nto leyo ebangela ukulibaziseka okukhulu kunye neendleko. Sizibiza ngokuba “zizinto eziyinxalenye enye” kunye “nezimbini” kuba zichaza ngokoqobo indlela umzimba wevalvu owakhiwe ngayo. Kulula kwaye kucacile. Xa iqela likaBudi liqeqesha abathengisi balo, kufuneka bagxininise ekusebenziseni la magama achanekileyo. Kufezekisa izinto ezimbini:

1. Ithintela Iimpazamo:Iqinisekisa ukuba ii-odolo zokuthenga ezithunyelwa kuthi ePntek zichanekile, ngoko ke sithumela imveliso echanekileyo abayifunayo ngaphandle kokudideka.
2. Igunya lokwakha:Xa abathengisi bakhe bemlungisa umthengi ngobunono (“Mhlawumbi ufuna ivalvu ‘eneenxalenye ezimbini’, mandikuchazele iingenelo…”), bazibeka njengeengcali, bakha ukuthembana nokuthembeka. Unxibelelwano olucacileyo aluyondlela ilungileyo nje kuphela; yinxalenye ephambili yeshishini eliphumelelayo nelinobuchule.

Yintoni ivalvu yebhola eneqhekeza elinye?

Udinga ivalvu elula nengabizi kakhulu kwisicelo esingabalulekanga. Ubona ivalvu engabizi kakhulu eneqhekeza elinye kodwa uxhalabile ukuba ixabiso layo liphantsi lithetha ukuba iza kusilela ngoko nangoko, nto leyo ebangela ingxaki engaphezulu kwexabiso layo.

Ivalvu yebhola eneqhekeza elinye yenziwe ngomzimba omnye obunjiweyo. Ibhola kunye nezitywino ziyafakwa, kwaye ivalvu ivalwe ngokusisigxina. Lukhetho oluthembekileyo nolungabizi kakhulu kwiizicelo apho kungadingeki ukulungiswa.

Cinga ngevalvu yebhola yeqhekeza elinye njengehashe elisebenzayo kwimisebenzi elula. Uphawu lwayo olucacileyo ngumzimba wayo—sisiqwenga esinye, esiqinileyo sePVC. Olu yilo lunemiphumo emibini ephambili. Okokuqala, ineendlela ezimbalwa kakhulu zokuvuza, kuba akukho mithungo yomzimba. Oku kuyenza ithembeke kakhulu ngexabiso layo. Okwesibini, akunakwenzeka ukuba ivuleke ukuze kulungiswe iindawo zangaphakathi. Ukuba isitywini siyaphela okanye ibhola yonakele, ivalvu yonke kufuneka isikwe kwaye itshintshwe. Yingakho sizibiza ngokuba “ziivalvu ezilahlwayo” okanye “ezilahlwayo”. Zikwanophawu “olusetyenziswa kakhulu”.izibuko elincitshisiweyo,” oko kuthetha ukuba umngxuma osebholeni mncinci kunobubanzi bombhobho, nto leyo enokuthintela ukuhamba kwamanzi kancinci. Ziyindlela efanelekileyo yoku:

• Iinkqubo zokunkcenkceshela kwiindawo zokuhlala.
• Imigca yamanzi yexeshana.
• Usetyenziso oluphantsi koxinzelelo.
• Nayiphi na imeko apho iindleko zomsebenzi wokutshintsha zingaphantsi kwexabiso eliphezulu levalvu enokulungiswa.

Yintoni ivalvu yebhola enamacandelo amabini?

Iprojekthi yakho ibandakanya umbhobho obalulekileyo ongenako ukumelana nexesha lokungasebenzi. Udinga ivalvu engapheleli nje ekubeni yomelele kodwa enokugcinwa lula iminyaka ezayo ngaphandle kokuvala yonke inkqubo.

Ivalvu yebhola enamacandelo amabini inomzimba owenziwe ngamacandelo amabini aphambili adibanisa iikrufu. Olu yilo luvumela ukuba ivalvu isuswe ukuze icocwe, ilungiswe, okanye ithathe indawo yebhola yangaphakathi kunye nezitywini.

Iivalvu yebhola enamacandelo amabinilukhetho oluqhelekileyo lweengcali kwiindlela ezininzi ezinzulu. Umzimba wayo wakhiwe ngamacala amabini. Isiqingatha esinye sinemisonto, kwaye esinye sifaka izikrufu kuso, sibambe ibhola kunye nezitywino (njengezihlalo ze-PTFE esizisebenzisayo ePntek) ngokuqinileyo endaweni yazo. Inzuzo enkulu kukubaukulungiswaUkuba isitywino siyaphela emva kweminyaka yokusebenza, awudingi sixhobo sokusika imibhobho. Ungayihlukanisa nje ivalvu, uyikhulule umzimba, uyitshintshe ikhithi yesitywino engabizi kakhulu, uze uyidibanise kwakhona. Iphinda isebenze ngemizuzu embalwa. Ezi valves phantse zihlala zisetyenziswa “izibuko elipheleleyo,” oko kuthetha ukuba umngxuma osebholeni ulingana nobubanzi bombhobho, okuqinisekisa ukuba akukho mda wokuhamba kwamanzi. Oku kubenza balungele:

• Imigca yenkqubo yemizi-mveliso.
• Imigca ephambili yokuhambisa amanzi kwizakhiwo.
• Ukuyikhupha kunye nokuhluza.
• Nayiphi na inkqubo apho isantya sokuhamba kwamanzi sibaluleke kakhulu kwaye ukuthembeka kwexesha elide yeyona nto iphambili.

Isiphelo

Ukhetho lulula: iivalvu ezinesiqwenga esinye zibiza kancinci kwaye azisetyenziswa xa kusetyenzwa imisebenzi engeyomfuneko. Iivalvu ezinesiqwenga esinye ziyakwazi ukulungiswa, zisebenza ngokupheleleyo kuyo nayiphi na inkqubo apho ukuthembeka kunye nexabiso lexesha elide kubaluleke kakhulu.
