Resilient Wedge Gate Valve
Resilient Wedge Gate Valve
Cov yam ntxwv ntawm lub rooj vag valve
Lub teeb yuag: Lub cev yog ua los ntawm cov qib siab ductile hlau, uas yog li 20% -30% sib dua li cov rooj vag li qub thiab yooj yim rau nruab thiab tswj. Flat-bottomed valve lub rooj zaum: Cov rooj vag qub qub feem ntau muaj cov khoom txawv teb chaws xws li pob zeb, ntoo blocks, cement, hlau filings, khib nyiab, thiab lwm yam. nyob rau hauv qhov zawj nyob rau hauv qab ntawm lub valve tom qab cov yeeb nkab yog flushed nrog dej, uas tau yooj yim. ua rau xau vim tsis muaj peev xwm kaw kom nruj. Hauv qab ntawm lub rooj zaum elastic lub rooj vag valve siv tib lub tiaj tiaj hauv qab tsim raws li cov yeeb nkab dej, uas tsis yooj yim los ua kom cov khib nyiab pov tseg thiab tso cai rau cov kua dej ntws zoo. Zuag qhia tag nrho cov roj hmab txheej: Lub valve siv cov roj hmab zoo rau tag nrho cov roj hmab sab hauv thiab sab nrauv. Teb chaws Europe cov cuab yeej siv roj hmab vulcanization siab tshaj plaws ua rau lub vulcanized valve kom tswj tau qhov tseeb geometric qhov ntev, thiab cov roj hmab thiab cov hlua hlau valve txuas ruaj khov thiab tsis yooj yim rau poob thiab elastic. Rov qab zoo. Precision cam khwb cia lub cev: Lub valve lub cev yog precision cam khwb cia. Qhov tseeb geometric qhov ntev ua kom lub sealing ntawm lub valve yam tsis muaj kev ua tiav hauv lub cev valve. Embedded tooj liab txiv ntseej: Cov txiv ntseej tooj liab thiab lub elastic valve tau kos rau hauv kev sib koom ua ke, kom ob leeg sib koom ua ke rau hauv ib qho, thiab yuav tsis xoob lossis puas vim kev co los ntawm cov dej ntws. Corrosion resistance: Lub cev valve yog coated nrog hmoov epoxy resin los tiv thaiv corrosion thiab xeb ntawm lub valve lub cev, thiab tuaj yeem siv rau hauv cov kav dej phwj tuaj. Tsis yooj yim rau tawg: yav dhau los, cov tsoos cam khwb cia hlau rooj vag li qub feem ntau tawg vim yog kev sib tsoo, kev sib tsoo lossis hnyav los ntawm cov khoom txawv teb chaws. Txij li thaum lub cev tseem ceeb yog ua los ntawm cov hlau nplaum, qhov xwm txheej no tuaj yeem txo qis heev. Peb "O" lub nplhaib ntsaws ruaj ruaj: Vim tias lub qia valve tau ntim nrog peb "O" lub nplhaib ntsaws ruaj ruaj, nws tuaj yeem txo kev sib txhuam thaum kaw, txo cov dej ntws tawm, thiab hloov lub nplhaib foob tsis muaj dej nres. Yooj yim rau haus dej nyoos: Sab hauv ntawm lub cev lub cev yog coated nrog cov tsis muaj tshuaj lom epoxy resin. Sab hauv thiab sab nrauv ntawm lub valve yog them tag nrho nrog roj hmab kom tsis txhob xeb lossis xeb, thiab nws yog qhov tsim nyog rau haus dej haus.
