Dab tsi yog lub qhov rooj vag riam polyurethane
Polyurethane riam rooj vag valvehais txog lub qhov rooj riam nrog lub foob polyurethane valve.Polyurethane (PU)muaj cov yam ntxwv ntawm kev tiv thaiv roj, kev tiv thaiv hnav, kev tiv thaiv kub qis, kev tiv thaiv kev laus, kev tawv siab, kev ywj pheej zoo heev thiab kev ua haujlwm tiv thaiv tshuaj lom. Nws feem ntau siv rau cov khoom me me thiab cov kav dej nruab nrab uas muaj roj thiab kua. Nws muaj kev ua tau zoo sealing thiab lub zog siab hnav.
Polyurethane hu ua "roj hmab uas tsis yooj yim hnav". Nws cov roj tsis kam tsis qis dua li roj hmab nitrile thiab sib npaug rau roj hmab polysulfide. Nws yog qhov tsim nyog rau ntau yam kav dej nruab nrab uas xav tau kev sib khi siab thiab kev yaig ntawm cov khoom me me.

Cov yam ntxwv tsim:
Polyurethane Riam Rooj Vag Valveuas ua rau nws yog ib qho ntawm cov ntaub ntawv zoo tshaj plaws uas tiv taus kev sib txhuam. Peb lub Polyurethane Knife Gate Valve (NSW) yog puv nrog cov urethane zoo, uas deb tshaj qhov hnav-lub neej ntawm cov roj hmab roj hmab thiab lwm yam softer liner, lossis cov ntaub ntawv tes tsho.
1.xoom qhov xauLub cev valve urethane puv nkaus thiab lub foob elastomer molded tiv thaiv kev xau mus tas li ob qho tib si lub valve sealing thiab lub cev valve nws tus kheej thaum lub sijhawm ua haujlwm.
2.Ntev hnav-lub neejCov ntaub urethane zoo uas tiv taus kev sib txhuam, thiab cov rooj vag riam stainless hlau ruaj khov nrog rau kev tsim tshwj xeeb ntawm lub valve nws tus kheej muab lub neej ua haujlwm ntev heev.
3.Kev kaw ob txoj kevThaum cov dej ntws rov qab los, NSW kuj siv tau ua ib qho tshuaj tiv thaiv thiab.
4.Kev tsim tus kheej ntxuavThaum lub sijhawm kaw lub valve, lub rooj vag riam beveled yuav hloov cov slurry ntws mus rau lub rooj zaum urethane liner beveled, tsim kev turbulence thiab ua kom cov dej ntws ntau ntxiv tom qab ntawd yaug cov slurry tawm ntawm hauv qab ntawm urethane thaum lub rooj vag nkag mus rau hauv lub rooj zaum.
5. Kev tsim kho dua tshiab yooj yimThaum kawg tsim nyog rov tsim kho dua tshiab, cov khoom siv hnav (urethanes, lub rooj vag foob, riam rooj vag) tuaj yeem hloov pauv tau hauv thaj teb. Lub cev valve thiab lwm yam khoom siv rov siv dua.
Cov kev xaiv
1. Lub Nplhaib Rooj Zaum (Cov Ntaub Npog):Muaj ntau hom urethanes.
2. Rooj vag Valve:Cov rooj vag SS304 nrog cov chromium coated nyuaj yog tus qauv. Lwm cov alloys muaj (SS316, 410, 416, 17-4PH…) Cov txheej txheem rooj vag xaiv tau kuj muaj.
3. PN10, PN16, PN25, 150LB, muaj.
4. Cov actuator xaiv tau muaj.
