Ukutshatisa iValve yeButterfly yePVC kwiNkqubo yakho yokunkcenkceshela
Ukuvavanya ireyithi yokuHamba kunye noxinzelelo
Yonke inkqubo yokunkcenkceshela idinga ivalve efanelekileyo ukulawula ukuhamba kwamanzi kunye noxinzelelo. Ivalve yebhabhathane ye-PVC isebenza kakuhle kwiindawo ezinoxinzelelo oluphantsi, ezingadlekiyo, kunye nobushushu obuphantsi. Uninzi lweenkqubo zokunkcenkceshela ezindlwini nakwiifama zihambelana nezi meko. Uxinzelelo lwenkqubo ludlala indima enkulu ekukhetheni ivalvu. Ivalve nganye inezinga loxinzelelo, njenge-ANSI okanye i-PN, ebonisa uxinzelelo oluphezulu olukhuselekileyo. Ukuba uxinzelelo lwenkqubo luhamba ngaphezu kwalo mda, i-valve inokusilela. Umzekelo, i PNTEKPLASTPVC butterfly valveiphatha uxinzelelo ukuya kuthi ga kwi-PN16 (232 PSI), iyenza ithembeke kwiindawo ezininzi zokuseta zokunkcenkceshela.
Ingcebiso: Soloko ujonga ubuninzi boxinzelelo lwesixokelelwano sakho phambi kokuba ukhethe isivalo. Ukuhlala ngaphakathi kwemida ebekiweyo kugcina inkqubo ikhuselekile kwaye isebenza kakuhle.
Iivalvu zebhabhathane zePVC zithandwa kakhulu kunkcenkceshelo kuba ziqala, ziyeke, kwaye zikwahlule ukuhamba kwamanzi ngokulula. Iindleko zabo eziphantsi kunye nokusebenza okulula kubenza ukuba bakhethe kakuhle iigadi, iingca kunye neefama.
Ukuqonda uMgangatho waManzi kunye nokuHambana kweMichiza
Umgangatho wamanzi uchaphazela ukuba ivalve ihlala ixesha elingakanani. Amanzi acocekileyo anceda ivalve isebenze ngcono kwaye ihlale ixesha elide. Ukuba amanzi aqulethe iikhemikhali, izichumisi, okanye intlenga, i-valve kufuneka ixhathise ukubola kunye nokwakhiwa. Iivalvu zebhabhathane zePVC zixhathisa iikhemikhali ezininzi ezifumaneka kumanzi okunkcenkceshela. Bakwaphatha udaka kunye namanye amasuntswana kakuhle, nto leyo ibalulekileyo kwiinkqubo zasefama nasegadini.
Qaphela: Soloko uthelekisa imathiriyeli yevalvu kunye neekhemikhali ezisemanzini akho. I-PVC isebenza kakuhle kwiimfuno ezininzi zokunkcenkceshela, kodwa jonga kabini ukuba amanzi akho aneeasidi ezinamandla okanye iikhemikhali ezingaqhelekanga.
Ukumisela ubungakanani boMbhobho kunye nohlobo lokuQhagamshela
Ukukhetha ubungakanani bombhobho ochanekileyo kunye nohlobo loxhulumaniso luqinisekisa ukuvuza okungavuziyo kunye nokufakela okulula. Uninzi lweenkqubo zokunkcenkceshela zisebenzisa ubungakanani bemibhobho eqhelekileyo. Le theyibhile ingezantsi ibonisa ubungakanani bombhobho oqhelekileyo kunye nobukhulu bevalvu kwezolimo:
| Ubungakanani bombhobho (ii-intshi) | Ngaphakathi Idayamitha (ii-intshi) | Idayamitha yangaphandle (ii-intshi) | Umlinganiselo woxinzelelo (PSI) | Amanqaku |
|---|---|---|---|---|
| 8″ | N / A | N / A | 80, 100, 125 | Umbhobho wokunkcenkceshela osemgangathweni |
| 10″ | 9.77 | 10.2 | 80 | Umbhobho wokunkcenkceshela wePVC onegasket |
| Uhlobo lweValve | Uluhlu lobungakanani (ii-intshi) | Izinto eziphathekayo | Isicelo |
|---|---|---|---|
| PVC Butterfly Valve | 2″, 2-1/2″, 3″, 4″, 5″, 6″, 8″, 10″, 12″, 14″, 16″ | I-PVC | Ukunkcenkceshela kwezolimo |
Imiba yohlobo loqhagamshelo lofakelo nokugcinwa. Kukho iintlobo ezintathu eziphambili: i-wafer, i-lug, kunye ne-flanged.
- Iivalvu zohlobo lwewafer zilingana phakathi kweeflange ezimbini kwaye zisebenzisa iibholiti ezidlula kumzimba wevalvu. Bagcina indawo kunye neendleko.
- Iivalvu zohlobo lwe-Lug zifakele imisonto ukuze kufakwe iibholiti kwaye zivumele ukususwa kwemibhobho esezantsi ukuze igcinwe.
- Ii-valve ze-Flanged-type zibophe ngokuthe ngqo kwiiflange zepayipi, zibenza zikhuseleke kwaye zilula ukulungelelanisa.
Ukulungelelaniswa okufanelekileyo, ukusetyenziswa kwe-gasket, kunye nokuqiniswa kwebholithi kunceda ukuthintela ukuvuza kunye nokwandisa ubomi bevalvu. Iivalvu zohlobo lweLug zenza ugcino lube lula kuba zivumela abasebenzisi ukuba basuse ivalve ngaphandle kokuphazamisa wonke umbhobho.
Ukukhetha uhlobo loqhagamshelwano oluchanekileyo lugcina ixesha ngexesha lofakelo kwaye lwenza ukulungiswa kwexesha elizayo kube lula.
Iimpawu eziphambili zePVC Butterfly Valve yokunkcenkceshela
Kutheni iPVC luKhetho oluSmart
Iivalve zebhabhathane zePVC zibonelela ngeenzuzo ezininzikwiinkqubo zokunkcenkceshela. Bagqama kuyilo lwabo olukhaphukhaphu, olwenza ukufakela kube lula nakwiiseti ezinkulu. Ukusebenza kweendleko zabo kunceda amafama kunye nabenzi bomhlaba bonge imali xa kuthelekiswa nentsimbi okanye ezinye iivalvu zeplastiki. I-PVC ixhathisa i-corrosion kwaye ayigqwali, ngoko ihlala ixesha elide kwiindawo ezimanzi. Umphezulu ogudileyo wezi zivalo uthintela ukuvuza kwaye wenze ukucoca kube lula.

Ukuhlolwa rhoqo rhoqo kwiinyanga ezi-6 ukuya kwezili-12 kunceda iindawo ezivuzayo, ukubola, okanye ukuguga. Coca umzimba wevalve kunye ne-actuator, thambisa amalungu ashukumayo, kwaye utshintshe izitywina okanye iigaskithi njengoko kufuneka. Inkqubo yolondolozo iqinisekisa ukuthembeka kwexesha elide.
Iivalvu ezifakwe kakuhle kunye nezilondolozwe kakuhle zinciphisa ukuvuza, ixesha lokuphumla, kunye nokulungiswa kweendleko.
Imigangatho kunye neziQinisekiso
Umgangatho kunye nokhuseleko kumba wokunkcenkceshela. Jonga iivalvu zebhabhathane zePVC ezihlangabezana nemigangatho yamazwe ngamazwe neyengingqi:
- I-DIN (Deutsches Institut für Normung)
- I-ANSI (iZiko leMigangatho yeSizwe yaseMelika)
- I-JIS (iMigangatho yoShishino lwaseJapan)
- I-BS (iMigangatho yaseBritani)
Iziqinisekiso ezifana ne-ISO 9001 kunye nokumakishwa kwe-CE kubonisa ukuba ivalve ihlangabezana neemfuneko ezingqongqo zomgangatho kunye nokhuseleko. Iziqinisekiso ze-NSF kunye ne-UPC ziqinisekisa ukufaneleka konikezelo lwamanzi kunye nokunkcenkceshela. Le migangatho kunye neziqinisekiso ziqinisekisa ukuhambelana, ukuthembeka, kunye noxolo lwengqondo.
- Vavanya iimfuno zenkqubo ngokujonga uxinzelelo, ukuhamba, kunye nokuhambelana.
- Khetha ubungakanani bevalve elungileyo, imathiriyeli, kunye nodidi loqhagamshelo.
- Faka kwaye ugcine ivalve ngokufanelekileyo ukuze ufumane iziphumo ezingcono.
Ukukhetha ngononophelo kunye nokuhlolwa rhoqo kunceda iinkqubo zokunkcenkceshela ziqhube kakuhle, zigcine amanzi, kunye neendleko eziphantsi ngexesha.
