Ib tug downhole kev ruaj ntseg valve uas yog ua los ntawm cov chaw saum npoo los ntawm kev tswj kab uas khi rau sab nraud ntawm cov tubing ntau lawm.
Kuj paub, Sssv valve yog dab tsi?
subsurface kev ruaj ntseg valve ( SSSV ) Ob hom kev nyab xeeb subsurface valve muaj: tswj qhov chaw thiab subsurface tswj. Hauv txhua kis, kev nyab xeeb- valve qhov system yog tsim los ua kom tsis muaj kev nyab xeeb, kom lub qhov dej sib cais nyob rau hauv qhov xwm txheej ntawm qhov system tsis ua haujlwm lossis kev puas tsuaj rau qhov chaw tsim khoom-tswj.
Ib yam li ntawd, lub subsurface kev nyab xeeb valve feem ntau qhib li cas? Nyob rau hauv ib txwm ua haujlwm, ob qho tib si subsurface kev ruaj ntseg li qub yog qhib thiab roj ntws upwardly los ntawm thawj tubing thiab nkag mandrel rau saum npoo. Gas los ntawm kev tsim nkag mus rau hauv lub tubing thib ob hauv qab lub dual packer thiab tawm hauv lub tubing thib ob los ntawm lub qhov cua saum lub packer dual.
Ua li no, lub subsurface kev nyab xeeb valve ua haujlwm li cas?
Ua hauj lwm Lub hauv paus ntsiab lus: Qhov kev txav no compresses lub caij nplooj ntoos hlav loj thiab thawb lub flapper (nyob rau hauv cov ntaub ntawv ntawm flapper hom SCSSV) los yog pob (nyob rau hauv cov pob hom SCSSV) downwards qhib lub valve . Thaum hydraulic siab yog tshem tawm, lub caij nplooj ntoos hlav thawb lub tes tsho rov qab thiab ua rau lub flapper (los yog pob) kaw.
Hom kev thaiv dab tsi yog qhov chaw tswj hwm subsea kev nyab xeeb valve?
Lub ntsiab kev nyab xeeb barrier ntawm tej qhov chaw tsim khoom yog qhov Surface Controlled Subsurface Safety Valve (SWV). Lub hom phiaj ntawm cov cuab yeej no yog kaw lub qhov dej thiab tiv thaiv kom tsis txhob muaj dej ntws mus rau ib puag ncig thaum muaj xwm txheej. nto kev puas tsuaj. SCSSV raug xa mus rau qhov tseem ceeb kev nyab xeeb barrier.

Sssv valve yog dab tsi?
Subsurface kev nyab xeeb valve (SSSV) Ob hom subsurface kev nyab xeeb valve muaj: tswj qhov chaw thiab subsurface tswj. Nyob rau hauv txhua rooj plaub, qhov kev ruaj ntseg-valve system yog tsim los ua tsis tau zoo, yog li ntawd lub qhov dej tau raug cais tawm thaum muaj kev tsis ua haujlwm lossis kev puas tsuaj rau cov chaw tsim khoom-tswj
Dab tsi yog lub hom phiaj ntawm kev sib tw valve?
Counterbalance li qub yog siv nyob rau hauv hydraulic systems ua hauj lwm nrog overriding (khiav-tawm) los yog tshem tawm load. Lawv yog tsim los tsim backpressure ntawm txoj kab rov qab ntawm tus actuator kom tsis txhob poob tswj lub load. Cov duab hauv qab no qhia txog qhov sib npaug ntawm lub valve schematic
Hom kev thaiv dab tsi yog qhov chaw tswj hwm subsea kev nyab xeeb valve?
Abstract: Qhov kev nyab xeeb tseem ceeb ntawm txhua yam khoom
Dab tsi yog hydraulic tswj valve?
Lub valve hydraulic kom zoo tswj cov dej ntws ntawm cov kua nruab nrab, feem ntau yog roj, los ntawm koj qhov system hydraulic. Hydraulic li qub tau muab faib ua peb pawg tseem ceeb: cov tswj kev tswj qhov qub, lub siab tswj li qub thiab ntws tswj li qub. Txhua lub valve ua haujlwm sib txawv hauv qhov system hydraulic
