Kev xaiv ntawm lub foob mos thiab lub foob rau lub npauj npaim valve yog nyob ntawm ntau yam, nrog rau cov kev thov tshwj xeeb, cov txheej txheem txheej txheem, thiab cov yam ntxwv ntawm cov kua dej ua haujlwm. Nov yog ib daim ntawv qhia los pab koj txiav txim siab:
Mos Foob (Rubber los yog Elastomer Seals):
Daim ntawv thov: Cov ntsaws ruaj ruaj yog feem ntau siv rau hauv cov ntawv thov uas yuav tsum tau kaw kom nruj, xws li kev kho dej, HVAC systems, thiab cov txheej txheem kev lag luam.
Qhov zoo:
Kev ua tau zoo sealing zoo: Cov ntsaws ruaj ruaj muag muab lub kaw ntom ntom tiv thaiv cov xau, txawm tias me ntsis misalignment ntawm lub valve disc thiab lub rooj zaum.
Kev tiv thaiv corrosion: Roj hmab lossis elastomeric cov ntaub ntawv feem ntau tiv taus corrosion thiab tshuaj tua kab mob, ua rau lawv tsim nyog rau kev tuav ntau yam dej.
Lub zog ua haujlwm qis: Cov ntsaws ruaj ruaj feem ntau yuav tsum tau ua haujlwm qis dua, ua rau kev ua haujlwm yooj yim dua thiab txo qis hnav ntawm cov khoom siv valve.
Kev txiav txim siab:
Cov kev txwv kub: Cov ntsaws ruaj ruaj yuav muaj qhov kub thiab txias, thiab qhov kub siab tuaj yeem ua rau degradation los yog tsis ua hauj lwm ntawm cov khoom foob.
Kev sib raug zoo nrog cov kua dej: xyuas kom meej tias cov khoom siv foob tau sib haum nrog cov kua dej ua haujlwm kom tsis txhob o, degradation, los yog paug ntawm cov txheej txheem.
Hard Foob (Hlau-rau-Hlau Seals):
Daim ntawv thov: Cov ntsaws ruaj ruaj yog tsim nyog rau qhov kub thiab txias, siab-siab, thiab abrasive daim ntaub ntawv, xws li roj thiab roj ua, tshuaj ua, thiab refining.
Qhov zoo:
High-temperature resistance: Hlau-rau-hlau ntsaws ruaj ruaj tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj degradation, ua rau lawv tsim nyog rau cov ntawv thov uas yuav tsum tau kub siab.
Abrasion tsis kam: Cov ntsaws ruaj ruaj tsis tshua muaj kev hnav thiab yaig los ntawm cov kua dej abrasive los yog cov khoom me me, muab kev pab lub neej ntev dua hauv qhov chaw hnyav.
Kev sib raug zoo nrog cov xwm txheej hnyav: Cov hlau ntsaws ruaj ruaj tuaj yeem tiv taus qhov hnyav hnyav, lub tshuab nqus tsev, thiab cov tshuaj lom neeg zoo dua li cov ntsaws ruaj ruaj.
Kev txiav txim siab:
Tight shut-off: Cov ntsaws ruaj ruaj yuav xav tau kev sib raug zoo ntawm lub valve disc thiab lub rooj zaum kom ua tiav qhov kaw nruj, uas tuaj yeem nyuaj rau qee qhov kev siv.
Kev khiav hauj lwm torque: Hlau-rau-hlau ntsaws ruaj ruaj tej zaum yuav xav tau ntau dua kev khiav hauj lwm torque piv rau cov ntsaws ruaj ruaj, uas yuav cuam tshuam rau lub actuation system thiab yuav tsum tau muaj zog actuators.
