Ingaba ipompo yakho ilahlekelwa yiprime yayo? Ivalvu yonyawo engasebenzi kakuhle ikhokelela ekubeni inkqubo ingasebenzi kwaye yonakale kakhulu. Ukukhetha izinto ezifanelekileyo, njengePVC okanye ibronze, lukhuselo lwakho lokuqala.

Kwiinkqubo ezininzi zamanzi, zokunkcenkceshela, kunye neekhemikhali, iivalvu zeenyawo zePVC zingcono ngenxa yokumelana kwazo nokugqwala kunye nexabiso eliphantsi. Ibrass ingcono kwiindlela zokusebenzisa ubushushu obuphezulu, kwimithombo enzulu, okanye apho kufuneka ukuqina okukhulu ngokuchasene nempembelelo yomzimba.

Ukukhetha nje izinto akwanelanga. Abaphathi abangcono bokuthenga, njengoCarlos, bayazi ukuba ixabiso lokwenyani lisekuqondeni iingenelo kunye neengxaki ezithile zokhetho ngalunye. Qhubeka ufunda, kuba olu lwazi lunzulu lulo olukhusela utyalo-mali lwakho kunye nokuthenjwa kwabathengi bakho.

Yeyiphi ivalvu yebrass okanye yePVC engcono?

Ubambeke phakathi kwentsimbi yesintu kunye nePVC yanamhlanje? Ukwenza ukhetho olungalunganga kunokukhokelela ekusileleni kwenkqubo kwangethuba kunye nokutshintshwa okubizayo. Masicacise ukuba yeyiphi efanelekileyo kuwe.

Iivalvu zePVC zingcono xa kusetyenziswa amanzi abandayo, ulwelo olubolayo, kunye nokungabi namali ingako. Iivalvu zebrass zingcono xa kusetyenziswa amanzi ashushu, igesi enoxinzelelo oluphezulu okanye imigca yomoya, kwaye apho imithetho yeenkqubo zamanzi okusela ifuna izinto zesinyithi.

Kumava am ePntek, ndibone abathengi besindisa amawaka kwiiprojekthi ngokutshintsha ukusuka kwi-bronze ukuya kwi-PVC apho kufanelekileyo. Umsasazi onjengoCarlos unokwakha inzuzo enkulu yokhuphiswano ngokukhokela abathengi bakhe kwisisombululo esingabizi kakhulu nesinokuthenjwa, kungekuphela nje kwesona siqhelekileyo. Ukhetho luxhomekeke kwiiyantlukwano ezimbalwa eziphambili.

Iipropati zezinto ezibonakalayo

Eyona nto iphambili kwingxoxo yile nto yenziweyo. I-Brass yintsimbi exutyiweyo, ngelixa i-PVC iyi-polymer. Oku kukhokelela kwiiyantlukwano ezibalulekileyo ekusebenzeni.I-PVC ayichaphazeleki ngokupheleleyo kukugqwala nokubolaemanzini kunye neekhemikhali ezahlukeneyo, nto leyo ebangela ukusilela okukhulu kweentsimbi. Nangona kunjalo, ithusi linokumelana namaqondo obushushu aphezulu kunye noxinzelelo ngaphandle kokuguquka. Ithusi likwanzima kakhulu kwaye liyakwazi ukumelana nefuthe lomzimba.

Iindleko kunye nokufakwa

Kulapho i-PVC ikhanya khona ngokwenene kumphathi wokuthenga. Iivalvu zePVC zibiza kakhulu ukwenziwa nokuthengwa. Ubunzima bazo obulula bukwathetha ukuba iindleko zokuthumela kunye nezothutho ziphantsi kwi-odolo nganye uCarlos ayibekayo. Ukufakelwa kwazo kulula kwaye kuyakhawuleza ngePVC, ngokuqhelekileyo kusetyenziswa isamente ye-solvent, edala ibhondi ehlala ihleli, engavuziyo. I-brass ifuna izixhobo ezinemisonto kunye ne-sealant, edinga umsebenzi omninzi.

Yeyiphi ivalvu yeenyawo engcono kakhulu?

Ucinga ukuba zonke iivalvu zeenyawo ziyafana? Ivalvu engayilwanga kakuhle iya kusilela, nto leyo ebangela ukuba ipompo yakho yome ize itshise. Eyona valve ilungileyo ineempawu ezithile ekufuneka uzijonge.

Uhlobo lwevalvu yeenyawo olungcono ludibanisa umzimba oqinileyo, ongaboliyo kunye nendlela yokutywina ethembekileyo kunye nesihluzo esenziwe kakuhle. Umzimba wePVC onetywina elifakwe ngentwasahlobo okanye irabha efakwe ilaphu udla ngokuba lolona khetho lusebenzayo noluhlala ixesha elide lokusetyenziswa kwamanzi.

Ivalvu yeenyawo "eyona ilungileyo"yileyo ingakwenzi ucinge ngayo emva kokuba ifakiwe. Isebenza nje. KuCarlos, ukufumana ivalvu yonyawo ethembekileyo ngokwenene kuthetha ukuba akukho zikhalazo zabathengi ezininzi kwaye kunika udumo oluqinileyo ngomgangatho. KwaPntek, sigxila kwiindawo ezintathu ezibalulekileyo ukuze sifezekise oku kuthembeka.

Indlela Yokuvala

Injongo iyonke yevalvu yenyawo kukugcina amanzi kumgca wokufunxa xa ipompo icinyiwe. Isitywino sibaluleke kakhulu.

• Igcwele entwasahlobo:Ezi zisebenzisa ispring ukutyhala idiski okanye ibhola kwisihlalo. Zinika isitywino esihle kakhulu kwaye zinokufakelwa kuyo nayiphi na indlela. Olu luyilo oluthembekileyo kakhulu.
• I-Flapper:Ilaphu elula yerabha okanye yeplastiki igquma umngxuma. Umxhuzulane kunye noxinzelelo lwamanzi kuyayinceda ukuba ivale. Ziyabiza kakhulu kwaye zisebenza kakuhle kodwa kufuneka zifakwe ngokuthe nkqo.
• Ibhola:Ibhola edadayo ihleli kwikheyiji ize ivale umngxuma xa amanzi eyeka ukuhamba. Luyilo olulula kodwa ngamanye amaxesha lunokubhajwa ukuba kukho inkunkuma.

Uyilo lweSwayina (Isikrini)

Isihluzo sendlela yokuqala yokuzikhusela kwivalvu, sithintela amagqabi, amatye, kunye nezinye izinto ezingafunekiyo ukuba zingangeni zize zonakalise ipompo. Isihluzo esilungileyo sinemingxuma emincinci ngokwaneleyo ukuvala amasuntswana awonakalisayo kodwa sikhulu ngokwaneleyo ukuba singathinteli kakhulu ukuhamba kwamanzi, nto leyo eya kucinezela ipompo. Sisebenzisa iPVC eqinisiweyo kwizihluzo zethu ukuqinisekisa ukuba aziwi okanye zibole ngokuhamba kwexesha.

Ukhetho lwezinto ezifunekayo kwisicelo

Njengoko sele sixoxile, izinto zomzimba zibalulekile. Kwiindawo zokunkcenkceshela, amachibi, kunye neenkqubo ezininzi zokuhambisa amanzi, i-PVC ifanelekile. Kwimithombo enzulu, enamatye apho ivalvu inokuba phantsi kwempembelelo, okanye kwiinkqubo zamanzi okusela, ivalvu yobhedu enzima, engenalo ilothe inokufuneka.

Zithini iingxaki zokufakelwa kwentsimbi?

Ngaba ibrass isoloko ilukhetho oluphezulu nolungenaxhala? Le nkolelo ixhaphakileyo inokufihla iingxaki ezibalulekileyo ezichaphazela umvuzo wakho. Ukuqonda ezi ngxaki kubalulekile ekuthengeni ngobulumko.

Eyona ngxaki iphambili yebrass ziindleko zayo eziphezulu, ubunzima bayo obonyusa iindleko zokuthunyelwa, kunye nokuba sesichengeni kwayo kuhlobo lokugqwala olubizwa ngokuba yi-dezincification, ingakumbi emanzini ane-chlorine ephezulu okanye amanqanaba aphantsi e-pH. Ezinye ii-alloys zebrass nazo ziqulathe i-lead.

Ndisoloko ndikhuthaza abathengi abanjengoCarlos ukuba bajonge ixabiso lilonke lobunini, kungekuphela nje ixabiso lokuqala. Nangona ibrass ivakala inkulu, ubuthathaka bayo bunokukhokelela kwiingxaki zexesha elide ezingenazo izinto ezifana nePVC. Imalunga nokukhetha isixhobo esifanelekileyo somsebenzi.

Ukuchithwa kwe-zincification kunye nokuhlaselwa ngamakhemikhali

I-Brass yingxubevange ye-copper kunye ne-zinc. Kwiimeko ezithile zamanzi, i-zinc inokukhutshwa ngokukhethayo kwindawo yokufaka, ishiye isakhiwo se-copper esibuthathaka nesingenazimbobo esinokuthi siqhekeke kwaye singaphumeleli. Oku kubizwa ngokubaukususwa kwe-zincification. Ibulala buthule iinkqubo zombhobho. Izixhobo ezenziwe ngePVC esemgangathweni azinawo amandla ngokupheleleyo kwezi meko, zibonelela ngobomi obuqikelelweyo nobuhlala ixesha elide kwiintlobo ngeentlobo zamanzi.

Ixabiso Lokwenyani: Ixabiso kunye nobunzima

Kumphathi wokuthenga, uhlahlo-lwabiwo mali lubalulekile. Ukufakelwa kwebrass kubiza kakhulu kunePVC, kudla ngokuba negalelo elikhulu. Kodwa ixabiso alipheleli apho. Ubhedu luxinene ngokuphindwe kasibhozo kunePVC. Oku kuthetha ukuba ukuthunyelwa ngakunye kweevalvu zebrass kunye nokufakelwa kubiza kakhulu kwiimpahla. Ngaphezulu konyaka, oku kongeza kwisixa esikhulu esichaphazela ngokuthe ngqo uhlahlo-lwabiwo mali lukaCarlos kunye nenzuzo yenkampani.

Impembelelo kuMsasazi

Ububi	Impembelelo kuMsasazi onjengoCarlos
Ixabiso Eliphezulu	Inzuzo ephantsi okanye amaxabiso angaphantsi kokhuphiswano.
Ubunzima Obunzima	Ukunyuka kweendleko zokuthumela kunye nezothutho kwi-odolo nganye.
Ukususwa kwe-zincification	Amathuba okuba izikhalazo zabathengi kunye namabango ewaranti afumaneke ngokuhamba kwexesha.
Umxholo okhokelayo	Kufuna ukufumana ii-alloys ezithile nezibiza kakhulu ezingenalo ilothe ukuze kusetyenziswe amanzi okusela.

Isiphelo

Kwiinkqubo ezininzi zamanzi,Iivalvu zeenyawo zePVCIxabiso layo eliphezulu kunye nokuthembeka ngenxa yokumelana nokugqwala kunye nexabiso eliphantsi. I-Brass sisisombululo esikhethekileyo sobushushu obuphezulu kunye noxinzelelo.
