Product Overview
Lub Non-Rising Stem Flanged Gate Valve yog tsim los rau ob-kev coj tus kav xa mus nyob qhov twg qhov chaw ntsug yog txwv. Nws lub hauv paus rotates los khiav lub rooj vag yam tsis tau ncua saum lub cev, ua rau nws zoo tagnrho rau underground vaults, valve chambers, thiab nruj piping skids.
Thaum qhib tag nrho, cov npoo uas muaj zog retracts tag nrho tawm ntawm txoj kev ntws, xa ib daim ntawv puv -ntev uas txo qis kev poob siab thiab tiv thaiv kev tawm xov xwm. Nruab nrog EPDM lossis NBR lub rooj zaum, nws ua kom xoom- kaw qhov dej tawm- tawm thoob plaws hauv nroog cov dej faib thiab cov khoom siv hluav taws xob.

Installation & Maintenance Recommendations
Ua ntej-Kev kuaj xyuas
• Xyuas kom tseeb tias qhov kev ntsuas siab, qhov loj ntawm lub valve, thiab flange drillings phim cov raj xa dej.
• Ntxuav cov kab kom huv si kom tshem tawm cov slag, av, thiab cov khib nyiab ua ntej kev teeb tsa.
• Tshawb xyuas flange ntsej muag thiab cov epoxy txheej rau shipping puas.
• Xyuas kom cov kav dej uas nyob ib sab yog anched kom tsis txhob muaj kev ntxhov siab rau lub cev valve.
Kev taw qhia kev teeb tsa
• Teem lub valve thiab cov yeeb nkab flanges ib txwm tsis yuam cov bolts rau hauv txoj hauj lwm.
• Hla-tighten flange bolts tusyees kom cov torque uas tau txais kev pom zoo.
• Lub voj voog lub valve qhib thiab kaw ua ntej txoj kab pressurization kom paub meej tias kev ua haujlwm zoo.
• Muab cov kua dej txaus txaus thiab kev ua haujlwm nkag mus rau cov ntaub ntawv faus lossis lub qhov.
