Lub micro resistance slow kaw valve (MRSCV) yog ib daim tshev valve uas nruab nrog qeeb -kaw mechanism. Cov txheej txheem no siv lub pas nrig tsis thiab lub caij nplooj ntoos hlav tsis tuaj yeem pab lub valve disc kaw. Thaum qhov nruab nrab ntws ntawm qhov siab tshaj plaws, lub valve disc raug rau inertial rog, ua kom ceev ceev kaw nyuaj thiab muaj peev xwm ua rau instantaneous siab sib txawv los yog txawm dej rauj. MRSCV, txawm li cas los xij, ua rau qis qis nruab nrab ntawm tus nqi ntws, txo qhov sib txawv ntawm qhov sib txawv, thiab tiv thaiv dej rauj.
Nta
MRSCV muaj cov yam ntxwv hauv qab no:
1. High Precision: Lub qeeb -kaw ntaus ntawv txo qhov nruab nrab ntws tus nqi, tso cai rau lub valve kaw maj mam thiab xyuas kom meej txaus tswj.
2. Slow-Closing Device: Ib lub pas nrig tsis thiab lub caij nplooj ntoos hlav tsis tuaj yeem pab lub valve kaw, txo qhov sib txawv ntawm qhov sib txawv thiab dej rauj.
3. Kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig: MRSCV txo qhov sib txawv ntawm qhov sib txawv thiab lub zog poob, yog li txhim kho cov kav dej kom zoo thiab txuag hluav taws xob.
4. Kev ruaj ntseg zoo: MRSCV siv cov hlau ntsaws ruaj ruaj, muab kev ruaj ntseg zoo dua thiab kev ntseeg siab nyob rau hauv ib puag ncig hnyav xws li kub, siab siab, thiab corrosive media.
Kev faib tawm
Cov txheej txheem kev faib tawm tseem ceeb rau MRSCVs yog:
1. Los ntawm cov qauv: suav nrog cov tshev valve thiab ob - txoj kev li qub.
2. Los ntawm txoj kev actuation: suav nrog phau ntawv, pneumatic, hydraulic, thiab hluav taws xob.
3. Los ntawm txoj kev sib txuas: suav nrog flange kev twb kev txuas, threaded kev twb kev txuas, clamp kev twb kev txuas, thiab lwm yam.
4. Los ntawm nruab nrab: nrog rau cov roj li qub thiab cov kua li qub.
Daim ntawv thov
MRSCVs tau siv dav hauv ntau lub tshuab tswj dej thiab khoom siv, xws li:
1. Hydraulic pipelines: MRSCVs tuaj yeem txo qhov nruab nrab ntws nrawm thiab nrawm nrawm sib txawv, ua kom muaj kev ua haujlwm zoo ntawm cov kav dej.
2. Hydropower: MRSCVs tuaj yeem tiv thaiv dej rauj, tiv thaiv kev ua haujlwm nyab xeeb ntawm cov tshuab hluav taws xob thiab cov dams.
3. Petrochemical kev lag luam: MRSCVs yog tus cwj pwm los ntawm qhov kub thiab txias tsis kam, corrosion kuj, thiab siab sib txawv tsis kam, thiab tau dav siv hauv cov tshuab petrochemical rau kev khiav dej num, kev tswj siab, thiab nruab nrab kaw -off.
4. Cov khoom siv kho mob: MRSCVs tsim nyog siv rau hauv cov khoom siv kho mob xws li cov tshuab xa tshuaj, lub tshuab ua pa, thiab cov tshuab hloov ntshav, uas muaj qhov ua tau zoo thiab ruaj khov.
