1) Installation yuav tsum:
① Cov li qub siv hauv cov raj xa dej ua npuas dej muaj xws li phau ntawv, hluav taws xob, pneumatic thiab hydraulic li qub.Peb qhov tom kawg no feem ntau yog siv hauv cov kav dej loj loj, lossis cov chaw taws teeb tswj thiab tsis siv neeg tswj.Lawv muaj lawv tus kheej cov qauv.Cov li qub uas siv rau hauv cov yeeb nkab ua npuas dej yuav tsum yog Rau kev teeb tsa raws li cov qauv tsim nyog, lub valve yuav tsum muaj cov cim qhib thiab kaw.
②Valves nrog cov chaw taws teeb tswj thiab tsis siv neeg tswj kev ua haujlwm yuav tsum tau teeb tsa raws li tus qauv tsim;Thaum lawv tau nruab rau hauv qhov chaw tawg thiab hluav taws kub, lawv yuav tsum ua raws li lub teb chaws tus qauv tam sim no "Electrical Installation Engineering Explosion and Fire Hazardous Environmental Electrical Installation Construction and Acceptance Specification 》(GB50257-1996).
③ Lub steel nce qia rooj vag valve thiab kos valve ntsia ntawm qhov chaw ua npuas dej ntawm lub dav hlau submerged thiab semi-submerged dav hlau ua npuas dej tua hluav taws nkag mus rau hauv lub tank cia yuav tsum tau teeb tsa kab rov tav, thiab cov kev taw qhia tau cim rau ntawm daim tshev valve yuav tsum yog. ua raws li cov kev taw qhia ntws ntawm cov npuas dej.Txwv tsis pub, cov npuas dej tsis tuaj yeem nkag mus rau hauv lub tank, tab sis qhov nruab nrab hauv lub tank yuav ntws rov qab rau hauv cov kav dej, ua rau muaj kev sib tsoo ntau dua.
④ Lub ntsuas siab, cov yeeb nkab lim, thiab tswj lub valve tau teeb tsa rau ntawm lub tshuab ua npuas dej sib xyaw ua ke ntawm qhov nkag ntawm lub tshuab hluav taws xob ua npuas siab siab yuav tsum tau nruab rau ntawm cov kav dej kab rov tav.
⑤ Lub tshuab nqus tsev tsis siv neeg tso rau ntawm lub tshuab ua npuas dej sib xyaw ua ke yuav tsum tau teeb tsa ntsug tom qab lub kaw lus tau dhau qhov kev ntsuas siab thiab ntws tawm.Qhov tsis siv neeg tso pa valve teem rau ntawm cov npuas dej sib xyaw ua ke yog cov khoom tshwj xeeb uas tuaj yeem tso cov pa tawm hauv cov kav dej.Thaum lub raj xa dej tau ntim nrog cov npuas dej sib tov (los yog ntim nrog dej thaum lub sij hawm debugging), cov roj hauv lub raj xa dej yuav raug tsav mus rau qhov siab tshaj plaws lossis qhov kawg sib sau ua ke ntawm cov roj hauv cov kav dej.Tsis siv neeg tso pa valve tuaj yeem tso tawm cov pa roj.Thaum lub raj xa dej Lub valve yuav cia li kaw tom qab tau ntim cov kua.Kev teeb tsa ntsug ntawm qhov tso tawm valve yog qhov yuav tsum tau ua ntawm cov khoom tsim.Lub installation yog nqa tawm tom qab lub kaw lus tau dhau qhov kev sim siab thiab dej ntws tawm kom tsis txhob muaj qhov thaiv thiab cuam tshuam rau cov pa tawm.
⑥ Lub valve tswj ntawm cov npuas dej sib xyaw ua ke txuas nrog lub tshuab ua npuas dej yuav tsum tau muab tso rau sab nraum lub ntsuas ntsuas qhov sib txuas sab nraum lub qhov hluav taws kub, nrog cov cim qhib thiab kaw;Thaum cov npuas dej sib xyaw ua ke tau teeb tsa rau hauv av, kev teeb tsa qhov siab ntawm kev tswj lub valve feem ntau tswj ntawm nruab nrab ntawm 1.1 thiab 1.5m, thaum lub cam khwb cia hlau tswj valve siv nyob rau hauv qhov chaw uas qhov kub thiab txias yog 0 ℃ thiab hauv qab, yog lub raj xa dej tau muab tso rau hauv av, lub cam khwb cia hlau tswj valve yuav tsum tau nruab rau ntawm riser;Yog hais tias lub raj xa dej tau faus rau hauv av los yog ntsia rau hauv lub trench, cam khwb cia hlau Lub valve tswj yuav tsum tau muab tso rau hauv lub valve zoo los yog trench, thiab kev tiv thaiv kev tiv thaiv yuav tsum tau ua.
⑦Thaum lub tshuab hluav taws kub ruaj khov hauv qhov chaw cia khoom kuj tseem muaj lub luag haujlwm ntawm lub tshuab hluav taws xob ib nrab, nws yog ib qho tsim nyog yuav tsum tau nruab ib lub yeeb nkab sib txuas nrog lub valve tswj thiab lub hau npog ntawm cov npuas dej sib xyaw ua ke sab nraum qhov hluav taws kub dike. pab txhawb cov tsheb tua hluav taws lossis lwm yam kev tua hluav taws txawb Cov khoom siv txuas nrog cov khoom siv hluav taws kub tua hluav taws hauv qhov chaw cia khoom.
⑧ Lub installation qhov siab ntawm kev tswj lub valve teem rau ntawm cov npuas dej sib xyaw ua ke yog feem ntau ntawm 1.1 thiab 1.5m, thiab qhov pom tseeb qhib thiab kaw yuav tsum tau teeb tsa;Thaum lub installation qhov siab ntawm cov tswj valve yog ntau tshaj 1.8m, ib qho kev khiav hauj lwm platform los yog lub lag luam yuav tsum tau teem quav.
⑨ Cov yeeb nkab xa rov qab nrog kev tswj valve ntsia rau ntawm cov yeeb nkab tawm ntawm lub twj tso kua hluav taws yuav tsum ua kom tau raws li cov qauv tsim.Lub installation qhov siab ntawm cov tswj valve feem ntau yog nruab nrab ntawm 0.6 thiab 1.2m.
⑩ Lub qhov cua valve ntawm lub raj xa dej yuav tsum tau muab tso rau ntawm qhov qis tshaj plaws kom yooj yim rau kev khiav tawm ntau tshaj plaws ntawm cov kua hauv cov kav dej.
2) Kev soj ntsuam txoj kev:cov khoom ① thiab ② raug soj ntsuam thiab tshuaj xyuas raws li qhov yuav tsum tau muaj ntawm cov qauv tsim nyog, thiab lwm yam kev soj ntsuam thiab kev tshuaj xyuas tus kav
