Cov khoom ntawm lub hard sealednpauj npaim valvetuaj yeem muaj feem cuam tshuam rau kev tswj hwm tus nqi ntws. Npauj npaim li qub feem ntau yog siv rau hauv ntau yam lag luam los tswj lossis tswj cov dej ntws, feem ntau hauv cov kav dej loj. Qhov kev xaiv ntawm cov khoom siv valve yog nyob ntawm daim ntawv thov tshwj xeeb thiab cov yam ntxwv ntawm cov kua dej tswj.
Thaum nws los txog rau cov khoom siv ntawm lub npauj npaim valve, muaj ntau yam kev xaiv, nrog rau cov hlau xws li cam khwb cia hlau, stainless hlau, carbon steel, thiab alloys, nrog rau cov khoom tsis yog xim hlau xws li PVC, CPVC, thiab ntau hom roj hmab. Txhua yam khoom muaj nws tus kheej cov khoom thiab tsim nyog rau kev ua haujlwm sib txawv.
Cov yam tseem ceeb uas yuav tsum tau xav txog thaum xaiv cov khoom siv rau lub npauj npaim valve uas yuav tswj tau qhov ceev ntawm qhov ntws muaj xws li:
Corrosion resistance: Cov khoom siv yuav tsum tiv taus corrosion los ntawm cov kua dej ntws los ntawm lub valve. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog thaum cuam tshuam nrog corrosive kua, xws li acids lossis tshuaj.
Siab thiab kub compatibility: Cov khoom siv yuav tsum muaj peev xwm tiv taus lub siab thiab kub ntawm lub cev yam tsis muaj deformation lossis tsis ua haujlwm. Cov ntaub ntawv sib txawv muaj qhov sib txawv siab thiab qhov ntsuas kub.
Abrasion tsis kam: Yog tias cov kua dej muaj cov khoom siv los yog abrasive nyob rau hauv cov xwm txheej, cov khoom siv valve yuav tsum muaj kev tiv thaiv txaus rau kev puas tsuaj kom ruaj khov thiab ua haujlwm ntev.
Chemical compatibility: Cov khoom siv yuav tsum sib haum nrog cov kua uas raug tswj kom tsis txhob muaj kev phiv los yog kev sib kis.
Sealing muaj peev xwm: Cov khoom siv yuav tsum muab kev sib khi zoo kom txo tau cov pa tawm thiab tswj xyuas qhov tseeb ntawm tus nqi ntws. Hard-sealed npauj npaim li qub feem ntau siv cov ntaub ntawv zoo xws li roj hmab lossis elastomers rau lub rooj zaum lossis cov khoom sib khi.
Nws yog ib qho tsim nyog sau cia tias thaum xaiv cov khoom tseem ceeb, lwm yam xws li kev tsim lub valve, cov duab disc, thiab cov txheej txheem ua haujlwm kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tswj cov nqi ntws zoo.
Hauv cov ntsiab lus, cov khoom siv ntawm lub zog-sau npauj npaim valve yog qhov tseem ceeb rau kev tswj xyuas qhov ceev ntawm qhov ntws. Kev xaiv cov khoom tsim nyog kom ntseeg tau tias kev ua tau zoo, ua haujlwm ntev, thiab kev tswj xyuas cov dej ntws zoo hauv daim ntawv thov.
