Hnav-resistant: Vim hais tias lub valve tseem ceeb ntawm ib qho nyuaj- foob pob valve yog ua los ntawm cov hlau alloy los ntawm cov tshuaj tsuag welding, thiab lub nplhaib sealing yog ua los ntawm cov hlau alloy los ntawm kev sib tshooj vuam, qhov nyuaj - foob pob valve tsis muaj qhov tseem ceeb thaum qhib thiab kaw. (Nws hardness coefficient yog 65-70).
Kev ua tau zoo ntawm kev sib khi: Lub foob ntawm ib qho nyuaj - foob pob valve tau ua tiav los ntawm kev sib tsoo los ntawm kev sib tsoo kom txog thaum lub valve tseem ceeb thiab lub nplhaib sealing zoo sib xws. Yog li ntawd, nws cov sealing kev ua tau zoo yog txhim khu kev qha.
Ib qho yooj yim qhib thiab kaw: Vim tias hauv qab ntawm lub nplhaib sib khi hauv ib qho nyuaj - foob pob valve siv lub caij nplooj ntoos hlav los tuav lub nplhaib sealing thiab valve core ua ke, qhib thiab kaw yog yooj yim heev txawm tias sab nraud quab yuam tshaj lub caij nplooj ntoos hlav preload.
Lub neej ua haujlwm ntev: Siv dav hauv roj av, tshuaj, hluav taws xob tsim hluav taws xob, papermaking, nuclear zog, aviation, foob pob hluav taws, thiab lwm yam haujlwm, nrog rau hauv lub neej txhua hnub.
Pneumatic pob li qub muaj ib qho yooj yim thiab compact qauv, txhim khu kev qha sealing, thiab yooj yim txij nkawm. Lub sealing nto thiab pob feem ntau yog nyob rau hauv lub xeev kaw, ua rau lawv tsis tshua muaj kev cuam tshuam los ntawm qhov nruab nrab. Lawv yooj yim rau kev khiav lag luam thiab tswj, tsim nyog rau kev ua hauj lwm xov xwm xws li dej, kuab tshuaj, acids, thiab natural gas. Lawv feem ntau yog siv los txiav tawm lossis txuas xov xwm hauv cov kav dej, thiab tseem tuaj yeem siv rau kev tswj hwm thiab tswj cov dej.
