Hard Foob Npauj Npaim Valve
Hard seal npauj npaim valve rau kev tiv thaiv
1. Lub welded bolts ntawm lub valve disk yuav tsum tsis txhob ntev dhau, txwv tsis pub lub bolts yuav ntev dhau lawm thiab tiv thaiv lub valve lub cev ntws txoj kev, ua rau lub sealing nto yog "hollow", tsis tuaj yeem ua lub luag haujlwm ntawm sealing; Kev sib dhos yuav tsum tau them sai sai rau kev kuaj xyuas thiab kho qhov qhib ntawm tus pas lo lo ntxhuav, kom ntseeg tau tias qhov chaw sib khi tuaj yeem ua kom nruj nruj.
2. Xaiv qhov kev hloov kho kom haum, lub thickness ntawm liner yuav tsum qis dua los yog sib npaug ntawm qhov siab ntawm lub valve disc sealing nto kauj ruam, kom cov mos mos gasket thiab valve disc sealing nto ze haum, nyob rau hauv tib lub dav hlau.
3. Txhawm rau tiv thaiv cov txiv ntoo compression los ntawm kev poob, cov txiv ntoo yuav tsum tau nruj me ntsis tom qab kev kho kom zoo los tiv thaiv loosening.
4. Yuav tsum xav txog kev siv cov kua dej tawm, xaiv cov gasket muag muag uas haum rau cov kev xav tau ntawm cov xov xwm, kom tsis txhob muaj kev tawm tsam los yog kub deformation thiab lwm yam cuam tshuam rau kev siv.
5. Thaum lub rooj zaum valve sealing nto puas yog qhov hnyav dua, lub rooj zaum valve tuaj yeem raug muab pov tseg, cov spool tuaj yeem txhim kho txuas ntxiv nrog tib cov lus qhia ntawm lub rooj zaum valve txhawb kev siv.
6. Kev hloov kho ntawm lub valve yuav tsum raug cim kom zoo, kom tsis txhob muaj kev kub ntxhov qhib thiab kaw, thiaj li tsis cuam tshuam rau lub neej kev pab cuam ntawm lub gasket.
