Wenze ukusikwa kwakho, kodwa itywina elivuzayo lithetha ukuchitha ixesha, imali kunye nezixhobo. Ijoyini enye embi kumgca wePVC inokukunyanzela ukuba usike icandelo lonke kwaye uqale phantsi.

Ukufakela i-valve yebhola kwipayipi ye-PVC, usebenzisa i-solvent welding. Oku kubandakanya ukusika umbhobho ngokucocekileyo, ukucima, ukusebenzisa i-PVC primer kunye nesamente kuzo zombini iindawo, emva koko uzityhalele kunye nekota ye-twist kwaye ubambe ngokuqinileyo de i-chemical bond iseti.

Oku asikokuncamathelisa nje; yinkqubo yemichiza edibanisa iplastiki ibe sisiqwenga esinye, esomeleleyo. Ukuyilungisa ayixoxisi kwabo balungileyo. Yinqaku endihlala ndicinezela kunye namaqabane afana noBudi e-Indonesia. Abathengi bakhe, nokuba ngaba zikontraki ezinkulu okanye abathengisi bendawo, baxhomekeke ekuthembekeni. Ilungu elingaphumeleliyo alikho nje ukuvuza; kukulibaziseka kweprojekthi kunye nokubetha igama labo. Makhe sigubungele imibuzo ebalulekileyo ukwenza ufakelo ngalunye lube yimpumelelo.

Udibanisa njani ivalve kumbhobho wePVC?

Unevalve esandleni, kodwa ujonge umbhobho ogudileyo. Uyazi ukuba kukho iintlobo zoqhagamshelo ezahlukeneyo, kodwa yeyiphi elungele umsebenzi wakho ukuqinisekisa ngenkqubo eyomeleleyo, engavuziyo?

Udibanisa ivalve kumbhobho wePVC ngenye yeendlela ezimbini: uxhulumaniso lwe-solvent-weld (socket) olusisigxina, olulungele i-PVC-to-PVC, okanye uxhulumaniso olunenkonzo olunentambo, olulungele ukujoyina i-PVC kumacandelo esinyithi njengeempompo.

Ukukhetha indlela efanelekileyo linyathelo lokuqala kufakelo lobungcali. Kwiinkqubo ezipheleleyo zePVC,ukuwelda okunyibilikayongumgangatho woshishino. Yenza ikhonkco elingenamthungo, elidityanisiweyo eliqine njengombhobho ngokwawo. Inkqubo iyakhawuleza, ithembekile, kwaye isisigxina. Uqhagamshelo olunemisonto lusetyenziswa xa ufuna ukudibanisa umgca wakho wePVC kwinto enemisonto yentsimbi ekhoyo, okanye xa ulindele ukuba ufuna ukususa ivalve ngokulula kamva. Nangona kunjalo, izifakelo zeplastiki eziphothiweyo kufuneka zifakwe ngononophelo ukuthintela iintanda ekuqiniseni ngokugqithisileyo. Kwimibhobho emininzi esemgangathweni yePVC, ndihlala ndicebisa ukomelela kunye nokulula koqhagamshelo lwe-solvent-weld. Xa inkonzo ingundoqo, aivelufa yebhola yomanyano lokweneneikunika okona kulungileyo kuwo omabini amazwe.

Yeyiphi indlela eyiyo yokufakela ivalve yebhola?

Ivalve incamatheliswe ngokugqibeleleyo, kodwa ngoku isibambo sibetha eludongeni kwaye asikwazi ukuvala. Okanye ufake ivalve yomanyano yokwenyani iqine kakhulu kwingqiniba kangangokuba awukwazi ukufumana isikrufu kuyo.

"Indlela efanelekileyo" yokufaka i-valve yebhola kukucwangcisa ukusebenza kwayo. Oku kuthetha ukuba owomileyo-ofanelekile kuqala ukuqinisekisa ukuba isiphatho sine-radius epheleleyo ye-90-degree kunye nokuba amantongomane omanyano afikeleleke ngokupheleleyo ekugcinweni kwexesha elizayo.

Ufakelo oluyimpumelelo ludlula nje aitywina elingavuziyo; imalunga nokusebenza kwexesha elide. Kulapho umzuzu wokucwangcisa ugcina iyure yokusebenza kwakhona. Ngaphambi kokuba uvule i-primer, beka ivalve kwindawo ekujoliswe kuyo kwaye ujiwule isibambo. Ngaba ihamba ngokukhululekileyo ukusuka ekuvuleni ngokupheleleyo ukuya ekuvalweni ngokupheleleyo? Ukuba akunjalo, kufuneka uhlengahlengise ukuqhelaniswa kwayo. Okwesibini, ukuba usebenzisa umgangatho ophezuluivelufa yomanyano lwenyaninjengeyethu ePntek, kufuneka uqinisekise ukuba unako ukufikelela kumanyano lwandongomane. Injongo yezi zivalo kukuvumela ukukhutshwa komzimba wevalve ngaphandle kokusika umbhobho. Ndihlala ndikhumbuza uBudi ukuba axelele abathengi bakhe oku: ukuba awukwazi ukufumana i-wrench kwi-nuts, woyisiwe yonke injongo yevalve. Yicinge njengokufakela kungekuphela nje okwanamhlanje, kodwa kumntu ekufuneka ayisebenzele iminyaka emihlanu ukusukela ngoku.

Ngaba iivalvu zebhola zePVC zijonge ngakumda?

Uyilungele ngesamente, kodwa uyanqumama, ngokungxama ujonge utolo oluhambayo kumzimba wevalvu. Uyazi ukuba ukuncamathelisa ivalve ngasemva kuya kuba yintlekele, impazamo eneendleko ezinkulu.

Hayi, ivalve yebhola yePVC esemgangathweni ayilathisi; inamacala amabini. Isebenzisa uyilo olulinganayo olunamatywina kumacala omabini, ukuyivumela ukuba ivale ukuhamba ngokulinganayo ukusuka kulo naliphi na icala. Ekuphela “kwesalathiso” omele uzikhathaze ngaso kukuziqhelanisa nomzimba wofikelelo lwesiphatho.

Lo ngumbuzo obalaseleyo kwaye oqhelekileyo. Isilumkiso sakho siyathetheleleka kuba ezinye iivalvu, njengekhangela iivalveokanye iivalvu zeglowubhu, zikhokele ngokupheleleyo kwaye ziya kusilela ukuba zifakwe ngasemva. Banotolo olwahlukileyo emzimbeni olukukhokelayo. Aivalve yebhola, nangona kunjalo, isebenza ngokwahlukileyo. Undoqo wayo yibhola elula enomngxuma kuyo, ejikelezayo ukutywina isihlalo. Kuba kukho isihlalo kwicala elinyukayo nelisezantsi lebhola, idala itywina eliqinileyo nokuba uxinzelelo luvela kweyiphi na indlela. Ngoko, unokuphumla. Awukwazi ukufaka ivalve yebhola esemgangathweni "ngasemva" malunga nokuhamba. Olu yilo lulula, lomelele sesinye sezizathu zokuba badume. Gxininisa nje ekubekeni ukuze isiphatho kunye neemanyano zibe lula ukufikelela kuzo.

Zithembeke kangakanani iivalvu zebhola zePVC?

Uyibonile ivalve yePVC etshiphu, engenagama iqhekeka okanye ivuza emva konyaka kuphela, ikwenza ubuze ngemathiriyeli ngokwayo. Uyazibuza ukuba kufuneka usebenzise ivalve yentsimbi ebiza kakhulu.

Iivalvu zebhola zePVC ezikumgangatho ophezulu zithembeke kakhulu kwaye zingahlala amashumi eminyaka. Ubomi babo bumiselwa ngumgangatho wezinto eziluhlaza (intombi enyulu vs. i-PVC ehlaziyiweyo), ukuchaneka kokuvelisa, kunye nokufakelwa okufanelekileyo. Ivalve esemgangathweni ikholisa ukodlula inkqubo ekuyo.

Ukuthembeka kwe-aIvalve yebhola yePVCyehla kwinto eyenziwe ngayo kunye nendlela eyenziwe ngayo. Lo ngundoqo wefilosofi yethu ePntek.

Yintoni Emisela Ukuthembeka?

• Umgangatho Wezinto:Sigxininisa ekusebenziseniI-100% ye-PVC enyulu. Iivalvu ezininzi ezinexabiso eliphantsi zisebenzisa izinto ezisetyenzisiweyo okanye zokuzalisa, nto leyo eyenza ukuba iplastiki ibemnkum kwaye ithande ukusilela phantsi koxinzelelo okanye ukuvezwa kwe-UV. I-PVC ye-Virgin inika amandla aphezulu kunye nokumelana nemichiza.
• Ukuchaneka koMveliso:Imveliso yethu ezenzekelayo iqinisekisa ukuba ivalve nganye iyafana. Ibhola kufuneka ingqukuva ngokugqibeleleyo kwaye izihlalo zigudile ngokugqibeleleyo ukuze zenze itywina eliqinileyo. Sivavanya iivalvu zethu ukuya kumgangatho ophezulu kakhulu kunokuba baya kuze bawubone ebaleni.
• Uyilo loBomi obude:Iimpawu ezinjengombutho womanyano wokwenyani, i-EPDM okanye i-FKM O-rings, kunye noyilo lwesiqu esomeleleyo zonke zinegalelo kubomi benkonzo obude. Lo ngumahluko phakathi kwenxalenye yokulahla kunye ne-asethi yexesha elide.

I-valve ye-PVC eyenziwe kakuhle, efakwe ngokufanelekileyo ayikho ikhonkco ebuthathaka; yinto ehlala ixesha elide, i-corrosion-proof, kunye nesisombululo esisebenzayo fo
