ET Control Valve nrog Trim Cartridge thiab 667 Actuator
Kev piav qhia
Trim Cartridge yog ib qho kev tswj xyuas tag nrho cov kev daws teeb meem uas suav nrog tag nrho cov kev txiav txim siab pom zoo cov npe khoom seem (RSPPL) hloov ntxiv rau lub kaus mom tshiab hauv ib zaug, lub Hoobkas sib dhos kho cov cartridge. Trim Cartridge muaj tib yam haum thiab kev ua haujlwm ntawm cov tsoos yooj yim-e trim, ua rau nws rov qab sib xws rau cov kev tsim kho yooj yim-e uas twb muaj lawm. Ntxiv nrog rau kev sib dhos ua ntej, txhua qhov Trim Cartridge raug kuaj xyuas kom ntseeg tau tias CL V shutoff muaj peev xwm thiab muaj cov khoom nyob hauv ENVIRO-SEAL ™ packing, tso cai rau kev txhim kho yooj yim uas txo cov sij hawm kho thiab nyuaj.

Kev tu
Kev tshuaj xyuas thiab kev saib xyuas zaus nyob ntawm qhov hnyav ntawm kev pabcuam. Thaum lub Trim Cartridge tau teeb tsa, lub kauv lub qhov txhab gasket (uas tsis tuaj yeem kho tau) yog compressed kom thauj khoom thiab kaw lub tawb gasket (daim duab 2, qhov tseem ceeb 4). Yog hais tias lub Trim Cartridge raug tshem tawm thiab rov nruab, lub kauv qhov txhab gasket yuav tsis muaj peev xwm txaus tom qab thawj zaug compression. Yog li ntawd, nws tsis pom zoo kom tshem tawm thiab rov nruab Trim Cartridge tom qab kev teeb tsa thawj zaug. Lub pob valve tuaj yeem muab kev pabcuam raws li nws tsis tas yuav tsum tau decompression ntawm kauv qhov txhab gasket. Tshooj lus no suav nrog cov lus qhia rau kev ntim khoom hauv Trim Cartridge.
Ntim Hloov
ENVIRO-SEAL packing systems yog tsim los rau kev ua tau zoo nyob rau lub sijhawm ntev. Qhov kev ua neej ntev no tso cai rau kev ntim khoom kom ua tau raws li kev teem caij cog qoob loo tsis tu ncua lossis hloov pauv. Siv cov lus qhia hauv qab no thaum kuaj lossis hloov ENVIRO SEAL packing. Cov ntaub ntawv ntxiv tuaj yeem pom nyob rau hauv ENVIRO-SEAL Sliding-Stem Valves Instruction Manual (D101642X012) Yog tias hloov cov khoom ntim khoom mus rau lwm yam khoom siv, xws li PTFE rau Graphite ULF, nws yog ib qho kev xyaum zoo los tshuaj xyuas cov actuator sizing, raws li kev sib txhuam. yuav hloov.
Phau ntawv qhia
1. cais cov tswj valve los ntawm txoj kab siab.
2. Tso lub siab thiab ntws cov txheej txheem tawm ntawm ob sab ntawm lub valve tswj.
3. Yog hais tias siv lub hwj chim actuator, kuj kaw tag nrho cov kab siab mus rau lub hwj chim actuator, thiab tso tag nrho cov siab ntawm tus actuator. Siv cov txheej txheem kaw-tawm kom paub tseeb tias cov kev ntsuas saum toj no nyob twj ywm thaum ua haujlwm ntawm cov khoom siv.
4. Tshem tawm cov kab khiav haujlwm ntawm lub tshuab hluav taws xob thiab cov kav dej xau tawm ntawm lub kaus mom.
5. Disconnect lub qia txuas thiab tom qab ntawd tshem tawm cov actuator ntawm lub valve los ntawm unscrewing lub yoke locknut.
6. Tshem tawm tej qhov taw qhia mus txawv tebchaws thiab qia locknuts ntawm lub valve qia threads.
7. Tshem cov txiv ntoo ntim khoom (daim duab 3, 4, lossis 5, qhov tseem ceeb 3) ntawm lub kaus mom.
8. Tshem tawm cov khoom ntim ntawm lub bore siv lub tshuab ntim cov khoom ntim thiab xyuas seb puas muaj kev puas tsuaj rau lub qia lossis lub thawv ntim khoom.
9. Nruab ENVIRO-SEAL cov khoom ntim rau hauv lub thawv ntim khoom. Siv daim duab 3, 4, lossis 5 kom ntseeg tau tias cov khoom ntim thiab lub caij nplooj ntoos hlav tau sib sau ua ke kom raug.
10. Txhim kho lub pob lub caij nplooj ntoos hlav nrog cov txuas txuas, mus rau lub qia, xyuas kom cov Belleville springs stacked kom zoo thiab cov thawv ntim khoom tau sib sau ua ke kom raug (daim duab 3, 4, lossis 5). Cov khoom ntim tsis tuaj yeem ua haujlwm tau zoo yog tias Belleville springs lossis lwm yam ntim khoom tsis tau muab sib dhos kom raug.
11. Lubricate lub ntim cov txiv ntoo (daim duab 3, 4, lossis 5, qhov tseem ceeb 3) nrog cov roj nplua nyeem los tiv thaiv thiab txhim kho tes kom nruj.
Tightening Procedures - Ntim Txiv Ntoo
1. Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws los ntawm ENVIRO-SEAL packing system, cov txiv ntoo ntim yuav tsum tau ntim cov Belleville springs rau lawv "lub hom phiaj load." Lub hom phiaj thauj khoom yog lub ntsiab lus uas Belleville springs yog tsim los rau kev ua tau zoo, thaum compressed rau 85 feem pua ntawm lawv qhov siab tshaj plaws deflection, los yog ze li ntawm lub tiaj. (Qhov siab tshaj plaws deflection yog thaum cov springs yog 100 feem pua compressed, los yog kiag li tiaj tus). Kom tau txais lub hom phiaj ntawm 85 feem pua compression ntawm qhov siab tshaj plaws deflection, ua cov hauv qab no:
· Tighten lub packing txiv ntoo kom txog thaum lub Belleville springs compressed 100 feem pua (los yog kiag li tiaj tus), raws li pom los ntawm ib tug ceev ceev ntawm cov txiv ntseej torque.
· Rau PTFE los yog Duplex packing, loosen packing flange txiv ntseej 1/2 tig (180 ntawm kev sib hloov).
· Rau Graphite ULF packing, loosen packing flange txiv ntoo 1/4 tig (90 ntawm kev sib hloov). Tam sim no lub "lub hom phiaj load" ntawm 85 feem pua compression tau mus txog. Xa mus rau qhov tsim nyog valve thiab actuator phau ntawv qhia thaum txuas lub valve rau tus actuator. Nyob rau hauv cov xwm txheej zoo li qub, cov txiv ntoo ntim khoom yuav tsum tsis tas yuav rov ua dua.
2. Txawm li cas los xij, thaum ua haujlwm, yog tias cov springs tsis nyob twj ywm ntawm lub hom phiaj ntawm 85 feem pua compression, retighten lub thawv ntim txiv ntoo raws li cov kauj ruam 1 saum toj no.
Lwm yam kev xav
Thaum repacking lub valve nrog ENVIRO-SEAL packing uas tau ua haujlwm, xyuas qhov xwm txheej ntawm cov khoom ntim tom qab lub ntim tau raug tshem tawm. Cov lus qhia zoo siv los kuaj xyuas qhov xwm txheej ntawm cov khoom ntim khoom yog 20/20 txoj cai. Yog tias tsawg dua 20 feem pua ntawm qhov chaw ntawm lub bore yog pitted thiab yog tias tsis muaj qhov tob tshaj 0.020 nti, ces cov ntim yuav tsum ua haujlwm raws li tsim. Qhov no tsis tas yuav yog qhov ntsuas qhov tseeb; kev tshuaj xyuas qhov muag yog txaus. Yog hais tias lub packing bore tsis ua raws li cov qauv no, chav tsev yuav tsum tau hloov.
