Txoj Cai Ua Haujlwm ntawm Kev Kub Ceev Breakaway Valve rau lub Loading Arm
Lub pob valve thaum muaj xwm txheej ceev rau kev thauj khoom caj npab yog ib qho khoom siv kev nyab xeeb, feem ntau ntsia rau pem hauv ntej kawg ntawm caj npab thauj khoom. Nws lub luag haujlwm tseem ceeb yog kom txiav thiab txiav tawm sai sai ntawm lub tank tsheb lossis lwm yam khoom siv txuas nrog thaum muaj xwm txheej ceev, xws li thaum lub tsheb thauj khoom tau ntsib qhov kev xav tau rub lossis siab dhau qhov kev txwv. Qhov no pab tiv thaiv kev thauj khoom caj npab thiab cov khoom siv cuam tshuam, tiv thaiv kev sib tsoo thiab ua kom muaj kev nyab xeeb thaum lub sijhawm thauj khoom thiab thauj khoom.
Lub RETAWAY VALVE (shruct-off valve) Cov kab mob ceev ceev maximical kev nyab xeeb hauv kev thauj mus los ob txhais caj npab (av raws li kev thauj khoom caj npab (av raws li kev thauj caj npab). Nrog rau kev tsim qauv yooj yim thiab tshwj xeeb, cov kab ke no tso cai rau kev thauj khoom kom muaj kev nyab xeeb disconnect cia li tsis to taub ntawm lub operating system. Thaum muaj kev phom sij, kev kub ntxhov breakaway valve (xwm ceev classe tawm valve) ua kom ceev ceev, thiab tsis tshua muaj siab poob. Tus me nyuam rhuav tshem cov tshuab ua kom cov khoom siv tau ua kom muaj kev cuam tshuam thaum muaj xwm txheej tsis muaj xwm txheej thaum muaj xwm txheej tsis muaj xwm txheej thaum muaj xwm txheej ceev, uas tuaj yeem cuam tshuam cov haujlwm ua haujlwm ib txwm muaj.
Kev Ua HaujlwmRaws li kev ua haujlwm ib txwm muaj kev mob, tom qab thauj khoom sab caj npab tau txuas rau tus txiv ntseej tau ua ntej (lub chav kev nyab xeeb yuav tsum tau muab qhib (lub qhov rai tau qhib kom pib lub chaw thau khoom lossis thauj khoom. Tom qab txoj haujlwm tiav lawm, kev nyab xeeb ntsia liaj npab yuav tsum rov kho dua, thiab cov caj npab thauj khoom tuaj yeem sib cais los ntawm lub tsheb loj los hloov kho caj npab. Thaum muaj xwm txheej ceev, yog tias lub tsheb nres tau ploj mus, kev rhuav tshem lub valve yuav cia li txav mus los ntawm kev sib tsoo ntawm lub tsheb thauj khoom thaum lub chaw thau khoom thiab thauj khoom.
Kev Nyab Xeeb Kev Nyab XeebLub chaw thau khoom caj npab thaum muaj xwm txheej ceev breakaway valve muaj kev ntseeg siab heev kaw, ua rau nws zoo tagnrho rau kev txiav tawm lossis tswj thiab throttling xov xwm. Nws tso cai rau cov cuab yeej txiav thiab txiav tawm sai sai thaum muaj xwm txheej ceev, zam kev tsis sib xws thaum ua haujlwm tsis tu ncua uas tuaj yeem cuam tshuam rau cov txheej txheem thauj khoom thiab tshem tawm. Tsis tas li ntawd, lub breakaway mechanism ua kom ntseeg tau tias cov cuab yeej tuaj yeem txiav thiab txiav tawm sai sai thaum muaj xwm txheej ceev, thaum muab lub sijhawm tsis zoo ua ntej kev sib txuas los tiv thaiv kev sib tsoo thaum lub sijhawm ua haujlwm ib txwm muaj.
Sealing PerformanceTom qab disconnection, qhov kawg txuas nrog lub hose yuav inevitably poob rau hauv av thiab raug dragged nrog rau lub tank tsheb. Txhawm rau tiv thaiv cov pob zeb los ntawm kev sib tsoo muaj zog, cov khoom siv feem ntau yog ua los ntawm stainless hlau (feem ntau 304) los yog tooj dag. Txawm li cas los xij, cov khoom siv thaum muaj xwm ceev disconnect rau lub loading caj npab yog txawv: qhov kawg yuav tsis poob rau hauv av, thiab carbon hlau yuav siv tau. Xav txog kev tiv thaiv xeb, tag nrho cov khoom hlau yog nto-coated nrog nyuaj chrome (los yog tshuaj lom neeg nickel-plated). Qhov no ua kom ntseeg tau tias tom qab qhov kev txiav tawm thaum muaj xwm txheej ceev, ob qhov sib cais tuaj yeem ua tau zoo.
Txheej Txheem Rov LosTom qab disconnection, lub raj xa dej yuav tsum tau ntws ua ntej kev kho dua tshiab. Ua ntej rov qab kho cov khoom siv thaum muaj xwm txheej ceev, cov ntsaws ruaj ruaj tseem ceeb thiab theem nrab yuav tsum tau kuaj xyuas kev puas tsuaj (xws li hlawv). Yog tias puas lawm, lub rooj zaum tseem ceeb yuav tsum tau muab tshem tawm thiab hloov lub ntsiab foob; txwv tsis pub, tsuas yog lub breakaway bolt yuav tsum tau hloov nrog ib tug tshiab.
