Dab tsi yog cov laj thawj rau qhov kev sib txuas ntawm lub pob hluav taws xob tsis siv neeg
Lub pob hluav taws xob valve muaj qhov ua haujlwm ntawm kev tig 90 degrees, lub cev ntsaws yog lub voos xwmfab, thiab muaj lub voj voog hla lub qhov lossis channel hla nws lub axis. Cov yam ntxwv tseem ceeb ntawm lub pob hluav taws xob valve yog cov qauv me me, kev sib khi txhim khu kev qha, cov qauv yooj yim, kev saib xyuas yooj yim, qhov chaw sib khi thiab qhov chaw kheej kheej feem ntau kaw, thiab tsis yooj yim rau kev puas tsuaj los ntawm cov khoom siv, yooj yim rau kev khiav lag luam thiab kev saib xyuas. Lub pob valve feem ntau yog siv hauv cov kav dej los txiav, faib thiab hloov cov kev taw qhia ntawm cov khoom siv. Nws tuaj yeem kaw nruj tsuas yog los ntawm kev tig 90 degree thiab lub sijhawm tig me me.
Lub pob valve yog qhov tsim nyog tshaj plaws rau kev hloov thiab kaw lub valve, tab sis tsis ntev los no, lub pob valve tau tsim los kom muaj kev tswj hwm thiab kev ntws, xws li v-ball valve. Nws yog qhov tsim nyog rau dej, cov kuab tshuaj, kua qaub thiab roj av, thiab tseem rau cov khoom siv uas muaj kev ua haujlwm tsis zoo, xws li oxygen, hydrogen peroxide, methane thiab ethylene, thiab lwm yam. Nws tau siv dav hauv ntau yam lag luam. Lub cev valve ntawm lub pob valve tuaj yeem ua ke lossis ua ke.
Cov yam ntxwv ntawm lub pob hluav taws xob
Lub pob hluav taws xob valve yooj yim hauv kev tsim kho, tsuas yog ob peb qhov chaw tau tsim, thiab kev siv cov ntaub ntawv tsawg dua; qhov ntim me me, qhov hnyav yog lub teeb, qhov loj me ntawm kev teeb tsa yog me me, thiab lub zog tsav tsheb yog me me. Lub valve tswj siab yog yooj yim thiab ceev rau kev ua haujlwm, thiab tuaj yeem qhib thiab kaw sai sai tsuas yog tig 90 ° thiab muaj cov txiaj ntsig zoo ntawm kev tswj hwm ntws thiab cov yam ntxwv sealing. Hauv kev siv ntawm lub cheeb loj thiab nruab nrab thiab qhov siab qis, lub pob hluav taws xob valve yog qhov xwm txheej valve ua ntej. Thaum lub pob hluav taws xob valve nyob rau hauv qhov chaw qhib tag nrho, qhov tuab ntawm npauj npaim phaj yog qhov tsis kam tsuas yog thaum cov nruab nrab ntws los ntawm lub cev valve. Yog li ntawd, qhov siab poob los ntawm lub valve yog me me heev, yog li nws muaj qhov zoo dua ntawm kev tswj hwm ntws.
