Ukufanisa iValve yeButterfly yePVC neNkqubo yakho yokuNcedisa
Ukuvavanya isantya sokuhamba kunye noxinzelelo
Yonke inkqubo yokunkcenkceshela ifuna ivalvu efanelekileyo yokulawula ukuhamba kwamanzi kunye noxinzelelo. Ivalvu yebhabhathane yePVC isebenza kakuhle kwiindawo ezinoxinzelelo oluphantsi, ezingaboliyo, kunye neendawo ezinobushushu obuphantsi. Uninzi lweenkqubo zokunkcenkceshela zasekhaya nasefama ziyahambelana nale meko. Uxinzelelo lwenkqubo ludlala indima enkulu ekukhetheni iivalvu. Ivalvu nganye inomlinganiselo woxinzelelo, njenge-ANSI okanye i-PN, ebonisa uxinzelelo lwayo oluphezulu olukhuselekileyo. Ukuba uxinzelelo lwenkqubo ludlula lo mda, ivalvu inokungaphumeleli. Umzekelo, iPNTEKPLASTivalvu yebhabhathane yePVCIphatha uxinzelelo olufikelela kwi-PN16 (232 PSI), nto leyo eyenza ukuba ithembeke kwiindawo ezininzi zokunkcenkceshela.
Icebiso: Soloko ujonga uxinzelelo oluphezulu lwenkqubo yakho ngaphambi kokuba ukhethe ivalvu. Ukuhlala ngaphakathi kwemida elinganisiweyo kugcina inkqubo ikhuselekile kwaye isebenza kakuhle.
Iivalvu zebhabhathane zePVC zithandwa kakhulu ekunkcenkcesheleni kuba ziqala, ziyeke, kwaye zihlukanise ukuhamba kwamanzi ngokulula. Ixabiso lazo eliphantsi kunye nokusebenza kwazo okulula kuzenza zibe lukhetho oluhle kwiigadi, utshani kunye neefama.
Ukuqonda Umgangatho Wamanzi kunye Nokuhambelana KwamaKhemikhali
Umgangatho wamanzi uchaphazela ixesha elithatha ivalvu. Amanzi acocekileyo anceda ivalvu isebenze ngcono kwaye ihlale ixesha elide. Ukuba amanzi aqulethe iikhemikhali, izichumisi, okanye inkunkuma, izinto zevalvu kufuneka zimelane nokugqwala kunye nokwakheka. Iivalvu zebhabhathane zePVC zimelana neekhemikhali ezininzi ezifumaneka emanzini okunkcenkceshela. Zikwaphatha udaka kunye nezinye iinxalenye kakuhle, nto leyo ibalulekileyo kwiinkqubo zasefama nasegadini.
Qaphela: Soloko ufanisa izinto zevalvu neekhemikhali ezikumanzi akho. I-PVC isebenza kakuhle kwiimfuno ezininzi zokunkcenkceshela, kodwa jonga kabini ukuba amanzi akho anee-asidi ezinamandla okanye iikhemikhali ezingaqhelekanga.
Ukumisela Ubungakanani Bepayipi kunye Nohlobo Loqhagamshelo
Ukukhetha ubungakanani obufanelekileyo bombhobho kunye nohlobo loqhagamshelo kuqinisekisa ukuba ukufakwa kwawo akuvuzi kwaye kulula. Uninzi lweenkqubo zokunkcenkceshela zisebenzisa ubungakanani obuqhelekileyo bombhobho. Itheyibhile engezantsi ibonisa ubungakanani obuqhelekileyo bombhobho kunye neevalvu kwezolimo:
| Ubungakanani bepayipi (ii-intshi) | Ububanzi bangaphakathi (ii-intshi) | Ububanzi obungaphandle (ii-intshi) | Uvavanyo loxinzelelo (i-PSI) | Amanqaku |
|---|---|---|---|---|
| 8″ | N / A | N / A | 80, 100, 125 | Umbhobho wokunkcenkceshela oqhelekileyo |
| 10″ | 9.77 | 10.2 | 80 | Umbhobho wokunkcenkceshela wePVC onegesi |
| Uhlobo lweValve | Uluhlu lobungakanani (ii-intshi) | Izinto eziphathekayo | Isicelo |
|---|---|---|---|
| Ivalvu yebhabhathane yePVC | 2″, 2-1/2″, 3″, 4″, 5″, 6″, 8″, 10″, 12″, 14″, 16″ | I-PVC | Ukunkcenkceshela kwezolimo |
Uhlobo loqhagamshelo lubalulekile ekufakelweni nasekugcinweni. Kukho iintlobo ezintathu eziphambili: i-wafer, i-lug, kunye ne-flanged.
- Iivalvu zohlobo lwe-wafer zingena phakathi kweeflange ezimbini kwaye zisebenzisa iibholithi ezidlula emzimbeni wevalvu. Zonga indawo kunye neendleko.
- Iivalvu zohlobo lwe-Lug zinezifakelo ezinemisonto zokubopha kwaye zivumela ukususwa kwemibhobho esezantsi ukuze igcinwe isemgangathweni.
- Iivalvu zohlobo lweFlanged zibopha ngqo kwiiflanges zepayipi, nto leyo ezenza ziqine kwaye kube lula ukuzilungelelanisa.
Ukulungelelaniswa okufanelekileyo, ukusetyenziswa kwe-gasket, kunye nokuqinisa ibholithi kunceda ekuthinteleni ukuvuza kunye nokwandisa ubomi bevalvu. Iivalvu zohlobo lwe-Lug zenza ukugcinwa kube lula kuba zivumela abasebenzisi ukuba basuse ivalvu ngaphandle kokuphazamisa yonke ipayipi.
Ukukhetha uhlobo olufanelekileyo loqhagamshelo konga ixesha ngexesha lokufakwa kwaye kwenza ukulungiswa kwexesha elizayo kube lula.
