Isantya esiphezulu sePneumatic Ball Valve
-
Uyilo kunye neMveliso
Ivalvu yebhola ephefumulayo enesantya esiphezulu isetyenziswa kakhulu kwiimeko zenkqubo apho kukho iimfuno ezingqongqo zesantya sokuvula nokuvala. Ifanelekile ukusetyenziswa kwiinkqubo zemibhobho ezifuna ukusika ngokukhawuleza okanye impendulo ekhawulezileyo, kwaye ifumaneka rhoqo kwiinkqubo zokusabela kwamakhemikhali ezibandakanya imidiya ekhethekileyo. Ngexesha lesigaba soyilo, ingqwalasela ikwisantya sesenzo, uzinzo lokusebenza, kunye nokhuseleko lwenkqubo, kwaye iyasebenza kwiinkqubo zolawulo ezinezinga eliphezulu lokuzenzekelayo.
Ivalvu ixhotyiswe nge-actuator ye-pneumatic ekhawulezayo, enesixhobo se-buffer ngaphakathi. Oku kwenza ukuba kuvulwe kwaye kuvalwe ngokukhawuleza ngelixa kunciphisa ngempumelelo impembelelo kwindawo yesiphelo sevalvu, kunciphisa umthwalo woomatshini emzimbeni wevalvu, isiqu sevalvu, kunye nezinto zokutywina, kwaye kunceda ukuphucula uzinzo lokusebenza ngokubanzi kunye nokwandisa ubomi benkonzo. Nokuba phantsi kweemeko zokusebenza ngokukhawuleza, inkqubo yokuvula nokuvala ivalvu ihlala ithambile, ithintela impembelelo ebalulekileyo kwinkqubo yemibhobho.
Indawo yokusilela kwe-actuator inokukhethwa ngokweemfuno zenkqubo kunye nokhuseleko, kwaye ingamiselwa njengendawo yokuvula iimpazamo, ukuvala iimpazamo, okanye indawo yokubamba iimpazamo. Ivalvu ixhasa ukusebenza kwendawo kunye nolawulo olukude, kwaye ingamiselwa ngee-positioners, ii-limit switches, ii-solenoid valves, kunye neemodyuli zonxibelelwano njengoko kufuneka, okwenza kube lula ukunxibelelana neenkqubo zolawulo ze-DCS okanye ze-PLC zolawulo oluphakathi kunye nokujonga imeko.
Ixesha lokusebenza kwevalvu linokumiselwa ngokweemeko zokusebenza zangempela, ukuhlangabezana neemfuno zokugqiba ukuvula nokuvala kwixesha elifutshane kakhulu, okanye ukufikelela kwinkqubo yesenzo ekhawulezayo egudileyo ngokulungiswa, okwenza ifaneleke ukusetyenziswa njengevalvu yenkqubo kwizixhobo ezikhethekileyo ze-medium chemical reaction.
