1, Valve xaiv thiab teeb tsa txoj haujlwm: (1) Cov valve siv hauv cov kav dej xa dej feem ntau xaiv raws li cov hauv qab no: 1. Thaum cov yeeb nkab txoj kab uas hla tsis tshaj 50 hli, yuav tsum siv lub valve nres. Thaum cov yeeb nkab txoj kab uas hla yog ntau tshaj 50 hli, lub rooj vag valve thiab npauj npaim valve yuav tsum tau siv 2. Thaum lub ndlwg thiab dej siab yuav tsum tau kho, lub regulating valve thiab nres valve yuav tsum tau siv 3. Ram valve yuav tsum tau siv rau qhov chaw nrog me me. dej tsis kam (xws li ntawm cov twj tso kua dej twj tso kua mis) 4. Lub rooj vag valve thiab npauj npaim valve yuav tsum tau siv rau ntawm cov yeeb nkab seem uas cov dej ntws yuav tsum tau ntws mus rau ob txoj kev, thiab nres valve yuav tsum tsis txhob siv 5. Npauj npaim valve thiab pob valve yuav tsum siv rau qhov chaw nrog qhov chaw me me 6. Nres valve yuav tsum tau siv rau cov yeeb nkab seem uas feem ntau qhib thiab kaw 7. Multi-function valve yuav tsum tau siv rau ntawm lub qhov hluav taws xob ntawm lub twj tso kua mis dej twj tso kua mis nrog loj caliber (2) li qub yuav tsum. muab nyob rau hauv cov nram qab no qhov chaw ntawm cov dej pipeline: 1. Cov kav dej nyob rau hauv cov tsev nyob yog los ntawm cov yeeb nkab seem ntawm lub municipal dej pipeline 2. Cov node ntawm sab nraum zoov lub nplhaib yeeb nkab network nyob rau hauv lub quarters yuav tsum tau teem raws li qhov yuav tsum tau ntawm. kev sib cais. Yog hais tias cov yeeb nkab annular ntev dhau lawm, nws raug nquahu kom teeb tsa lub valve 3. Qhov pib kawg ntawm ceg yeeb nkab lossis qhov pib kawg ntawm cov yeeb nkab txuas los ntawm cov kav dej loj ntawm cov tsev nyob 4. Cov kav dej hauv tsev, dej ntsuas thiab txhua ceg riser (hauv qab ntawm riser thiab sab sauv thiab qis ntawm ntsug annular yeeb nkab network riser) 5. Lub ntsiab yeeb nkab ntawm lub nplhaib yeeb nkab network thiab txuas cov yeeb nkab los ntawm ceg yeeb nkab network 6. Qhov pib taw tes ntawm cov yeeb nkab xa tawm txuas los ntawm sab hauv tsev Cov kav dej xa mus rau tsev neeg, chav dej pej xeem, thiab lwm yam yuav tsum tau teeb tsa thaum qhov chaw faib khoom ntawm cov kav xa dej ntau tshaj 3 7. Cov kav dej tawm ntawm lub twj tso kua mis, lub twj tso kua mis ntawm tus kheej filling twj tso kua mis 8. Cov kav dej tawm thiab qhov hluav taws xob thiab tso cov kav dej ntawm cov tso tsheb hlau luam 9. Cov dej nkag thiab cov kav dej ua rau cov khoom siv (xws li lub rhaub dej, lub tshuab cua txias, thiab lwm yam) 10. Cov kav dej xa dej rau cov khoom siv huv huv (xws li loj, tso zis tso quav, ntxhua khaub ncaws, da dej, thiab lwm yam.) 11. Qee yam khoom siv, xws li tsis siv neeg tso tawm valve, lub siab nyem valve, dej rauj tshem tawm, ntsuas qhov siab, lub tshuab nqus dej, thiab lwm yam, lub siab txo valve thiab rov qab tiv thaiv, thiab lwm yam 12. Qhov qis tshaj ntawm cov dej xa dej network yuav tsum tau nruab nrog cov dej tso tawm. valve (3) Feem ntau, kos valve yuav tsum raug xaiv raws li qhov chaw teeb tsa, dej siab nyob rau hauv pem hauv ntej ntawm lub valve, sealing kev ua tau zoo tom qab kaw thiab dej rauj loj los ntawm kev kaw 1. Thaum cov dej siab nyob rau hauv pem hauv ntej ntawm lub valve, viav vias , pob thiab shuttle check li qub yuav tsum raug xaiv 2. Thaum lub sealing kev ua tau zoo tom qab kaw yog nruj, nws yog advisable mus xaiv lub check valve nrog kaw lub caij nplooj ntoos hlav 3. Thaum nws yuav tsum tau kom tsis muaj zog lub kaw dej rauj, nws yog advisable mus xaiv lub valve. Lub kaw lus kaw nrawm nrawm lossis lub kaw kaw qeeb nrog cov khoom siv damping 4. Lub valve tawg lossis lub valve tseem ceeb ntawm daim tshev valve yuav tsum tau kaw los ntawm nws tus kheej raws li qhov kev txiav txim ntawm lub ntiajteb txawj nqus los yog lub caij nplooj ntoos hlav quab yuam （4） Cov pob valve yuav tsum muab rau ntawm qhov cov ntu hauv qab no ntawm cov kav dej xa dej: Ntawm cov yeeb nkab inlet; nyob rau hauv lub kaw dej rhaub los yog cov khoom siv dej; nyob rau hauv lub twj tso kua mis qhov hluav taws xob yeeb nkab; nyob rau hauv lub qhov hluav taws xob yeeb nkab ntawm lub tank dej, cov dej ntauwd thiab highland pas dej ua ke qhov twg cov dej inlet thiab qhov hluav taws xob kav sib koom ib tug yeeb nkab. Nco tseg: cov yeeb nkab seem nrog cov yeeb nkab rov qab tiv thaiv tsis tas yuav tsum tau nruab cov kos valve. (5) Cov khoom siv hluav taws xob yuav tsum tau muab rau ntawm qhov chaw hauv qab no ntawm cov kav dej xa dej: 1.
