PVC foot valve
PVC hauv qab valve yog ib hom kev txuag hluav taws xob, uas feem ntau yog ntsia rau hauv qab kawg ntawm cov dej nqus cov yeeb nkab ntawm cov twj tso kua dej kom txwv cov kua hauv cov dej twj tso kua mis los ntawm kev rov qab mus rau qhov dej, ua haujlwm ntawm tsuas nkag tab sis tsis tawm. Muaj ntau cov dej nkag thiab cov hlua khi rau ntawm lub valve npog, uas tsis yooj yim los thaiv. Lub valve hauv qab yog lub teeb hauv qhov hnyav thiab yooj yim rau nruab.
Cov txheej txheem kev sib txuas yog: hom kev sib txuas, thiab cov qauv khoom yog: hom ntab ntab.Nws tuaj yeem siv nrog ntau yam twj centrifugal thiab cov twj tso kua mis tus kheej.
Cov khoom muaj ib tug tshiab qauv thiab superior sealing kev ua tau zoo. Nws tuaj yeem tiv taus cov kua qaub, alkali thiab corrosion. Lub sijhawm siv ntev. Nws yog dav siv hauv kev lag luam tshuaj, tshuaj fiber ntau, chlor-alkali, hluav taws xob, tshuaj, tshuaj tua kab, zas, smelting, khoom noj khoom haus, dej phwj tuaj, mariculture, thiab lwm yam lag luam.
PVC yog cov hmoov dawb nrog cov qauv amorphous. Lub degree ntawm branching yog me me, tus txheeb ze ceev yog hais txog 1.4, lub iav hloov kub yog 77 ~ 90 ℃, thiab nws pib decompose ntawm txog 170 ℃. Nws muaj kev ruaj ntseg tsis zoo rau lub teeb thiab cua sov, siab dua 100 ℃ lossis tom qab lub sijhawm ntev. Kev raug rau lub hnub ci yuav decompose los tsim hydrogen chloride, uas yuav ntxiv autocatalyze lub decomposition, ua rau discoloration, thiab lub cev thiab txhua yam khoom yuav poob sai sai. Hauv kev siv cov tswv yim, stabilizers yuav tsum tau ntxiv los txhim kho cov cua sov thiab lub teeb ruaj khov.
Nta
