Khoom Description
Qhov no CPVC (Chlorinated Polyvinyl Chloride) wafer npauj npaim valve tswj kev ntws hauv cov tshuaj corrosive thiab siab - cov kua dej kub txog 200℃F (93℃). Ua nrog tag nrho -liner lub rooj tsim, lub valve cais lub cev los ntawm cov kav dej tawm. Nws hloov cov hlau tsis muaj steel lossis cov hlua hlau li qub hauv nruab nrab- cov ntawv thov siab, txo cov kav dej qhov hnyav thiab tshem tawm cov galvanic corrosion sab nraud. Tau tshaj ANSI B16.5 Class 150 bolt qauv, nws haum ncaj qha ntawm tus qauv flanges.
Cov yam ntxwv tseem ceeb ntawm cov khoom
Tag Nrho -Liner Lub Cev cais tawm:Lub elastomer liner npog tag nrho lub cev sab hauv phab ntsa thiab flange lub ntsej muag, tshem tawm cov kua sib cuag nrog lub valve vaj tsev thiab tiv thaiv qia to.
Corrosion & Temperature Resistance:Cell chav kawm 23447 CPVC cov ntaub ntawv tuav cov txheej txheem rigidity thiab tshuaj inertness nyob rau hauv kub acid, alkali, thiab ntsev txaus.

FAQ
Q: Yuav ua li cas CPVC piv rau PVC rau npauj npaim valve xaiv?
A: CPVC txhawb kev khiav hauj lwm kub txog 200℃F (93 degree), hos tus qauv PVC yog txwv rau 140℃F (60 degree). CPVC tseem muab kev cuam tshuam ntau zog thiab dav dua tshuaj tiv thaiv tiv thaiv cov kua qaub ntawm qhov kub siab.
Q: Lub CPVC npauj npaim valve no puas tuaj yeem nruab rau qhov kawg ntawm cov kav dej?
A: Tsis yog. Wafer-style npauj npaim li qub yuav tsum tau clamping ntawm ob lub yeeb nkab flanges rau kev txhawb nqa thiab lub rooj sib khi. Xaus- ntawm- kab kev pabcuam yuav tsum muaj lub nra-style npauj npaim valve nrog threaded inserts.
Q: Dab tsi flange gaskets yuav tsum tau rau installation?
A: Tsis xav tau cov flange gaskets. Tag nrho - lub rooj zaum liner folds nyob ib ncig ntawm lub ntsej muag lub ntsej muag, ua raws li kev sib koom ua ke tiv thaiv tus khub tiaj tus - lub ntsej muag flanges.
Q: Puas yog lub valve no sib haum nrog hlau khub flanges?
A: Yog. Txawm li cas los xij, tiaj tus- ntsej muag khub flanges yog qhov yuav tsum tau ua. Mating kom tsa- ntsej muag hlau flanges tuaj yeem ua rau tsis sib xws kev ntxhov siab thiab tawg lub nplhaib yas flange thaum torqued.
Q: Yuav ua li cas torque qauv yuav tsum tau siv thaum zawm flange bolts?
A: Tighten bolts nyob rau hauv lub hnub qub (criss{0}}cross) qauv nyob rau hauv incremental cov kauj ruam (30%, 60%, 100% ntawm lub hom phiaj torque) siv lub torque ciaj ntswj. Xa mus rau phau ntawv qhia tshwj xeeb ft-lb txwv kom tiv thaiv lub cev deformation.
Q: Puas yog cov rooj zaum thiab cov discs muaj rau kev saib xyuas thaj chaw?
A: Yog. Hloov EPDM / FKM lub rooj zaum, CPVC discs, thiab qia sib dhos tuaj yeem raug txiav txim rau kev kho dua tshiab.
