Yuav tsum tau rub tawm Valve rau Tank Truck Loading thiab Unloading

Rub tawm li qub ua lub luag haujlwm tseem ceeb hauv kev thauj cov roj, thiab hnub no, Editor Hua De yuav tham txog qhov tsim nyog ntawm lawv ua ke.
Vim muaj cov yam ntxwv ntawm flammability, explosiveness, thiab muaj zog corrosiveness ntawm ntau cov khoom siv tshuaj, muaj kev pheej hmoo loj hauv kev khaws cia thiab kev thauj mus los ntawm cov khoom siv tshuaj. Kev tsis saib xyuas yooj yim tuaj yeem ua rau muaj xwm txheej xws li hluav taws kub, tawg, thiab ib puag ncig muaj kuab paug. Cov xwm txheej loj tuaj yeem cuam tshuam tsis zoo rau kev nyab xeeb hauv zej zog. Yog li ntawd, nrog rau txoj kev loj hlob ntawm tib neeg thiab kev lag luam, nrog rau kev nce ntxiv ntawm lub teb chaws rau kev tiv thaiv ib puag ncig, kev nyab xeeb thiab kev tswj hwm ib puag ncig rau kev lag luam tshuaj tau ua nruj zuj zus. Yog li ntawd, cov tuam txhab tsim khoom muaj feem cuam tshuam tau maj mam nthuav tawm cov cuab yeej kev nyab xeeb thiab cov khoom siv rau hauv cov kab ntau lawm kom paub meej cov qauv kev nyab xeeb, qhia meej txog qhov yuav tsum tau teeb tsa cov khoom sib tsoo ntawm cov kav dej, uas feem ntau hu ua rupture li qub.
Vim li cas thiaj txhim kho lub valve tawg?
Yog tias cov xwm txheej hauv qab no tshwm sim tsis tau xav txog:
Vim yog kev ua haujlwm tsis raug lossis zawv zawg vim li cas, lub tank tsheb tau tawm ntawm qhov chaw ua haujlwm ua ntej yuav raug cais tawm ntawm lub hose (los yog cov khoom siv), ua rau muaj cov khoom siv loj heev thiab ua rau muaj kev nyab xeeb loj los ntawm kev rub thiab rhuav tshem cov yeeb nkab txuas; Thaum lub tank tsheb thauj khoom thiab thauj khoom, yog tias muaj hluav taws kub nyhiab lossis lwm yam laj thawj ntawm qhov chaw, nws yuav tsum tau khiav tawm ntawm qhov chaw sai sai. Yog tias lub tank tsheb thauj khoom thiab lub tsheb thauj khoom tsis tuaj yeem sib cais los ntawm kev siv ib txwm, nws tuaj yeem ua rau muaj kev nyab xeeb ntawm tus kheej thiab khoom ntiag tug, ua rau kev lag luam poob thiab ib puag ncig muaj kuab lom. Txhawm rau tiv thaiv kev sib tsoo thiab txo qis kev sib tsoo, equip loading thiab unloading cov cuab yeej nrog thaum muaj xwm ceev tso tawm li qub yog ib qho kev ntsuas loj los xyuas kom meej kev nyab xeeb thiab ib puag ncig tiv thaiv ntawm kev cia thiab kev thauj mus los ntawm petrochemical raw cov ntaub ntawv.
Rub tawm li qub yog siv los nruab rau ntawm qhov chaw thau khoom thiab tshem tawm cov hoses lossis cov khoom siv ntawm cov khoom siv tshuaj lom neeg (xws li kua propane, ammonia, ethylene oxide, liquefied petroleum gas LPG, butadiene, industrial methanol, natural gas LNG, kua chlorine, carbon dioxide) nyob rau hauv lub tank tsheb (tsheb ciav hlau, tsheb). Raws li kev ua haujlwm ib txwm muaj, thaum raug rau qee qhov kev quab yuam sab nraud, lub qhov rooj kaw qhov xwm txheej ceev yuav txiav tawm thiab muaj kev nyab xeeb, thiab ob qhov kawg yuav cia li kaw yam tsis muaj cov dej xau, tiv thaiv kev nyab xeeb ntawm cov kav dej thiab cov khoom siv. Lub rub tawm valve ua kom muaj kev nyab xeeb siab tshaj plaws ntawm cov txheej txheem xa dej thaum lub sijhawm thauj khoom thiab tshem tawm.
