Phau Ntawv Qhia rau Npauj Npaim Valve Installation

Qhov tseeb installation ntawm anpauj npaim valveNws yog ib qho tseem ceeb rau nws cov sealing kev ua tau zoo thiab kev pab lub neej. Cov ntaub ntawv no qhia txog cov txheej txheem kev teeb tsa, cov kev xav tseem ceeb, thiab qhia txog qhov sib txawv ntawm ob hom: wafer-style thiabflanged npauj npaim li qub. Wafer-style li qub, uas tau teeb tsa ntawm ob lub flanges flanges siv stud bolts, muaj cov txheej txheem kev teeb tsa nyuaj dua. Nyob rau hauv sib piv, flanged npauj npaim li qub tuaj nrog ib qho flanges thiab ncaj qha bolted rau mating pipeline flanges, ua kom yooj yim cov txheej txheem.

Lub flange bolts rau wafer npauj npaim valve yog qhov ntev. Lawv qhov ntev yog xam raws li: 2x flange thickness + valve thickness + 2x txiv ntseej thickness. Qhov no yog vim lub wafer npauj npaim valve nws tus kheej tsis muaj flanges. Yog tias cov bolts thiab txiv ntoo raug tshem tawm, cov kav dej ntawm ob sab ntawm lub valve yuav cuam tshuam thiab tsis tuaj yeem ua haujlwm li qub.

Flanged li qub siv cov bolts luv, nrog qhov ntev txhais tau tias yog 2x flange thickness + 2x txiv ntseej thickness, los txuas lub valve tus kheej flanges ncaj qha rau cov nyob hauv cov kav dej. Ib qho txiaj ntsig tseem ceeb ntawm qhov kev tsim no yog tias nws tso cai rau ib sab kom tsis txhob cuam tshuam tsis cuam tshuam kev ua haujlwm ntawm cov kav dej sib txuas.

Qhov tsab xov xwm no tsuas yog qhia cov lus qhia installation rau wafer npauj npaim li qub los ntawmTWS.

Lub wafer npauj npaim valve nta ib qho yooj yim, compact, thiab lub teeb yuag tsim nrog ob peb yam. Nws ua haujlwm nrog ceev 90 ° kev sib hloov, ua kom yooj yim rau / tawm tswj thiab muab kev tswj xyuas zoo heev.

I. Cov lus qhia ua ntej kev teeb tsaWafer-hom Npauj Npaim Valve

1. Ua ntej kev teeb tsa pib, lub raj xa dej yuav tsum tau muab tshem tawm ntawm cov khoom txawv teb chaws uas siv cov cua compressed thiab tom qab ntawd ntxuav nrog dej huv.
2. Ua tib zoo xyuas seb qhov kev siv ntawm lub valve ua raws li nws qhov kev ua tau zoo (kub, siab).
3. Tshawb xyuas lub valve thiab sealing nto rau cov khib nyiab, thiab tshem tawm tam sim ntawd.
4. Tom qab unpacking, lub valve yuav tsum tau ntsia tam sim ntawd. Tsis txhob loosen tej fastening screws los yog ceev ntawm lub valve arbitrarily.
5. Tus npauj npaim valve flange tshwj xeeb yuav tsum tau siv rau wafer hom npauj npaim li qub.
6. Covhluav taws xob npauj npaim valvetuaj yeem ntsia tau rau ntawm cov kav dej ntawm txhua lub kaum sab xis, tab sis kom yooj yim txij nkawm, nws raug nquahu kom tsis txhob nruab nws upside down.
7. Thaum txhim kho tus npauj npaim valve flange, nws yog ib qho tseem ceeb los xyuas kom meej tias lub flange lub ntsej muag thiab cov roj hmab sealing zoo sib xws, cov bolts tau nruj sib npaug, thiab lub sealing nto yuav tsum haum tag nrho. Yog tias cov bolts tsis tau nruj nruj, nws yuav ua rau cov roj hmab tuaj yeem ua rau lub pob tawg, los yog thawb tawm ntawm lub disc, uas ua rau cov pa tawm ntawm lub valve qia.

II.Installation: Wafer Npauj Npaim Valve

Txhawm rau ua kom lub foob tsis muaj paug thiab muaj kev nyab xeeb, txhim khu kev lag luam ntawm npauj npaim valve, ua raws li cov txheej txheem kev teeb tsa hauv qab no.

1. Raws li qhia, tso lub valve ntawm ob lub flanges pre-installed, kom ntseeg tau tias cov ntsia liaj qhov rooj qhov sib raug zoo.

2. Maj mam ntxig plaub khub ntawm bolts thiab txiv ntseej rau hauv lub qhov flange, thiab me ntsis zawm cov txiv ntoo kom kho qhov flatness ntawm flange nto;

3. Siv qhov chaw welding kom ruaj ntseg flange rau cov kav dej.

4. Tshem tawm lub valve;

5. Ua tiav qhov flange rau lub raj xa dej.

6. Nruab lub valve tsuas yog tom qab lub welded sib koom ua ke tau txias. Xyuas kom meej tias lub valve muaj chav txaus txav mus rau hauv lub flange los tiv thaiv kev puas tsuaj thiab lub valve disc tuaj yeem qhib rau qee qhov kev kawm.

7. Kho lub valve txoj hauj lwm thiab zawm plaub khub ntawm bolts (ceev ceev tsis txhob overtighten).

8. Qhib lub valve kom ntseeg tau tias lub disc tuaj yeem txav tau yooj yim, ces qhib lub disc me ntsis.

9. Siv tus qauv ntoo khaub lig kom nruj tag nrho cov txiv ntoo.

10. Paub meej ib zaug ntxiv tias lub valve tuaj yeem qhib thiab kaw tau dawb. Nco tseg: Xyuas kom lub valve disc tsis kov lub raj xa dej.

Txhawm rau kom muaj kev nyab xeeb, tsis muaj kev ua haujlwm ntawm wafer npauj npaim li qub, ua raws li cov hauv qab no:

• Kov nrog Kev Saib Xyuas: Khaws lub valve kom ruaj ntseg thiab tsis txhob cuam tshuam.
• Align Precisely: Ua kom zoo meej flange kev sib raug zoo kom tiv thaiv kom tsis txhob xau.
• Tsis txhob Disassemble: Thaum ntsia, lub valve yuav tsum tsis txhob dismantled nyob rau hauv lub tshav pob.
• Txhim Kho Kev Txhawb Nqa Mus Ib Txhis: Txhim kho lub valve nrog kev txhawb nqa uas yuav tsum nyob hauv qhov chaw.
