I-Stainless Valve Stem kwiNkonzo yeValve yeShishini
Kwiindibano ezininzi zeevalvu, isiqu asitsali ngqalelo ingako. Iingxoxo ezininzi zihlala zigxila kumzimba wevalvu okanye kuyilo lokutywina. Nangona kunjalo, ngokoqobo, isiqu yinxalenye ehamba rhoqo xa ivalvu isebenza. I-torque evela kwi-handwheel okanye kwi-actuator idluliselwa kwisiqu, ngoko ke imeko yayo ichaphazela ngokuthe ngqo ukuba ivalvu ingavuleka okanye ivale kakuhle.
Ngenxa yesi sizathu, abavelisi abaninzi bakhetha ukusebenzisa isiqu sevalvu esingenasici endaweni yentsimbi yekhabhoni. Iivalvu zoshishino zihlala zisebenza kwiindawo apho kukho umswakama, utshintsho lobushushu okanye imidiya yeekhemikhali. Ngexesha elide lokusebenza ezi meko zinokubangela ukugqwala kwiindawo zentsimbi eziqhelekileyo. Isiqu esingenasici sihlala sisebenza ngcono phantsi kwezi meko kwaye sihlala sigcina imeko yaso yomphezulu ixesha elide.
Izinto ezifana nentsimbi engagqwaliyo engama-304 kunye ne-316 zisetyenziswa kakhulu kule njongo. Zinika amandla afanelekileyo ngelixa zikwanika ukumelana nokugqwala okuhle. Kwezinye iindlela zoyilo lweevalvu, ingakumbi xa kufuneka amandla aphezulu oomatshini, intsimbi engagqwaliyo engama-17-4PH nayo inokukhethwa. Ezi zinto zihlala zifumaneka kwiivalvu zebhola, iivalvu zesango kunye neevalvu zeglobe ezisetyenziswa kwizityalo zepetrochemical, iinkqubo zamanzi kunye neminye imibhobho yemizi-mveliso.
Ngokwembono yoomatshini, ukuvelisa isiqu sevalvu esingenasici ifuna ingqalelo kwiinkcukacha ezininzi. Icandelo lesiqu esidlula kwiphakheji kufuneka libe nomphezulu ozinzileyo. Ukuba umphezulu urhabaxa kakhulu, ukuguguleka kokupakisha kunokwanda ngexesha lokusebenza. Ekuhambeni kwexesha oko kunokukhokelela ekuvuzeni okanye ekubunzimeni xa usebenzisa ivalvu.
Ngenxa yesi sizathu, isiqu sidla ngokuveliswa ngokujika kwe-CNC kulandele imisebenzi yokuthunga kunye nokugqiba. Ubukhulu obuphambili bujongwa ngononophelo, ingakumbi kwiindawo zokuvala. Kwiifektri ezininzi isatifiketi sezinto siyaqinisekiswa ukuze umgangatho we-stainless ungalandelelwa ukuba kuyimfuneko.
Nangona isiqu siyinxalenye enye kuphela ngaphakathi kwendibano yevalvu, sidlala indima ebalulekileyo ekusebenzeni kwemihla ngemihla. Xa umgangatho wezinto kunye noomatshini kulawulwa ngokufanelekileyo, isiqu sevalvu esingenasici inokuhlala izinzile iminyaka emininzi yenkonzo, yiyo loo nto iqhubeka isetyenziswa kakhulu kwimveliso yeevalvu zoshishino.
