Hauv Jinbin lub rooj cob qhia, lwm pawg ntawm cov flange soft-sealed gate valves tau npaj txhij rau kev xa khoom, suav nrog cov qia zais.flange mos-sealed rooj vag valvethiab lub qhov rooj vag flange uas qhib tau, nrog rau qhov loj ntawm DN80 thiab DN100, thiab ua los ntawm hlau cam khwb cia QT450. Raws li cov neeg ua haujlwm tsim kho kav dej thiab kev ua haujlwm thiab kev saib xyuas, kev xaiv lub qhov rooj vag flange mos mos uas kaw tau zoo tsis tsuas yog tshem tawm cov kev pheej hmoo xau xwb tab sis kuj ua rau lub neej ua haujlwm ntev dua thiab txo cov nqi ua haujlwm thiab kev saib xyuas. Thaum yuav khoom, tsis tas yuav sib piv cov nqi. Ua tib zoo saib cov ntsiab lus tseem ceeb: sib phim cov xwm txheej ua haujlwm, cov ntaub ntawv zoo, cov txheej txheem tsim khoom txheem, thiab kev pabcuam tom qab muag zoo. Tsis txhob ua raws li cov nqi qis. Tsuas yog los ntawm kev sib npaug zoo thiab kev ua tau zoo ntawm tus nqi koj tuaj yeem xaiv lub qhov rooj vag flange uas ntseeg tau thiab ruaj khov.

Ua ntej, phim cov kev cai ua haujlwm. Ua ntej tshaj plaws, xyuas seb lub yeeb nkab siab thiab txoj kab uas hla yog dab tsi. Rau cov dej xa dej thiab cov dej ntws thiab cov tshuab tiv thaiv hluav taws, 1.0/1.6 MPa feem ntau txaus. Txawm li cas los xij, thaum muaj qhov kub thiab txias, yuav tsum hloov kho qib kev tiv thaiv siab. Tib lub sijhawm, qhia meej txog hom khoom siv. Cov ntaub ntawv sib khi sib txawv yog qhov tsim nyog rau cov dej ntshiab thiab cov dej phwj kom tiv thaiv kev xeb ntawm cov khoom thiab kev laus sai. 

Qhov thib ob, xyuam xim rau qhov zoo ntawm lub cev valve thiab lub foob.lub qhov rooj dejLub cev yuav tsum ua los ntawm cov hlau ductile, uas muaj zog thiab tiv taus kev hloov pauv. Tsis txhob siv cov khoom siv casting uas tsis zoo. Lub foob mos yog lub hauv paus. Nws raug pom zoo kom xaiv EPDM lossis NBR integral molded sealing parts, uas muaj elasticity zoo thiab muaj zog sealing, tuaj yeem ua tiav xoom to, thiab tiv thaiv cov dej ntws, to thiab teeb meem seeping.

Tsis tas li ntawd xwb, yuav tsum tau ua tib zoo saib xyuas cov qauv thiab kev ua haujlwm. Nyiam cov qauv qia zais, uas siv qhov chaw tsawg dua thiab tsis tshua muaj plua plav thiab xeb. Lub ntsej muag kawg ntawm flange yuav tsum tiaj tus thiab tsis muaj qhov tsis zoo, nrog rau cov qhov ntsia hlau kom yooj yim rau kev teeb tsa thiab kev sib txuas ntawm qhov chaw. Lub qhov rooj valve qia yuav tsum du thiab tsis lo, ua rau yooj yim qhib thiab kaw, thiab nws yuav tsum tsis txhob lo txawm tias siv ntev.

Thaum kawg, xyuam xim rau cov kev tsim nyog thiab kev pabcuam tom qab muag. Thov cov ntawv qhia txog cov ntaub ntawv thiab daim ntawv pov thawj tshuaj xyuas, thiab tsis lees txais cov khoom yam tsis muaj cov ntaub ntawv. Muab qhov tseem ceeb rau cov chaw tsim khoom nrog kev pabcuam tom qab muag tiav, kev lees paub zoo meej, thiab cov lus teb sai. Txhua yam teeb meem yav tom ntej tuaj yeem daws tau sai. Jinbin Valve tau tsim cov li qub zoo rau 20 xyoo (Chaw Tsim Khoom Rooj Vag), nrog rau kev lees paub zoo. Yog tias koj muaj kev xav tau cuam tshuam, thov hu rau peb hauv qab no. Koj yuav tau txais lus teb hauv 24 teev!
