Raws li cov yam ntxwv ntawm cov qauv thiab kev siv, lawv tuaj yeem muab faib ua ob pawg:
1. Cov npauj npaim valve kaw
Hom npauj npaim valve no tuaj yeem ua kom tiav sealing thaum kaw, thiab tuaj yeem siv los ua kev txiav tawm hauv cov kav dej. Nws cov sealing khub tuaj yeem txais cov foob mos (rubber lossis yas) lossis hlau foob qauv.
Cov npauj npaim kaw nrog cov qauv muag muag feem ntau txais cov kab hauv nruab nrab ntawm cov roj hmab hauv ob sab phlu, fluoroplastic hauv ob sab phlu lossis peb cov qauv eccentric.
Cov npauj npaim kaw nrog cov qauv hlau foob feem ntau txais ob npaug eccentric lossis peb eccentric qauv. Feem ntauhlau foob npauj npaim li qubsuav nrog ntau txheej peb eccentric hlau foob qauv, U-shaped resilient foob nplhaib hlau foob npauj npaim valve thiab kev ua haujlwm siab hlau foob npauj npaim valve.
2. Non-sealed npauj npaim li qub
Cov npauj npaim uas tsis muaj qhov tsis tuaj yeem tsis tuaj yeem ua kom tiav kev sib khi thaum kaw, thiab lawv cov xau yuav tsum ua tau raws li qib B, C, thiab D ntawm ISO5208. Hom valve no yog siv rau kev hloov kho hauv cov kav dej lossis hauv cov kav dej nrog cov kev xav tau lax sealing. Nws cov khoom siv sib khi feem ntau yog siv cov qauv hlau foob.
