Ivalvesisixhobo esisetyenziswa ekusasazeni nasekulawuleni irhasi nolwelo ubuncinane iminyaka eliwaka yembali.
Okwangoku, kwinkqubo yepayipi yamanzi, i-valve elawulayo yinto yokulawula, kwaye umsebenzi wayo oyintloko kukuhlukanisa izixhobo kunye nenkqubo yombhobho, ukulungelelanisa ukuhamba, ukuthintela umva, ukulawula nokukhupha uxinzelelo. Ekubeni kubaluleke kakhulu ukukhetha i-valve efanelekileyo yokulawula inkqubo yepayipi, kubaluleke kakhulu ukuqonda iimpawu zevalve kunye namanyathelo kunye nesiseko sokukhetha i-valve.
Uxinzelelo oluncinci lwevalve
Uxinzelelo oluqhelekileyo lwevalvu lubhekisa kuyilo olunikiweyo loxinzelelo olunxulumene namandla omatshini amacandelo okubhobhoza, oko kukuthi, luxinzelelo olusebenzayo oluvumelekileyo lwevalve kubushushu obuchaziweyo, obunxulumene nezinto zevalve. . Uxinzelelo olusebenzayo alufani, ngoko ke, uxinzelelo lwegama luyiparameter exhomekeke kwizinto eziphathekayo zevalve kwaye ihambelana nokushisa okuvumelekileyo okusebenzayo kunye noxinzelelo olusebenzayo lwezinto.
I-valve isibonelelo kwinkqubo yokujikeleza okuphakathi okanye inkqubo yoxinzelelo, esetyenziselwa ukulungelelanisa ukuhamba okanye ukunyanzeliswa kwe-medium. Eminye imisebenzi ibandakanya ukuvala okanye ukucima imidiya, ukulawula ukuhamba, ukutshintsha indlela yokuhamba kwemidiya, ukuthintela ukubuya kweendaba, kunye nokulawula okanye ukukhupha uxinzelelo.
Le misebenzi ifezekiswa ngokulungelelanisa indawo yokuvalwa kwevalve. Olu hlengahlengiso lunokwenziwa ngesandla okanye ngokuzenzekelayo. Ukusebenza ngesandla kukwabandakanya ukusebenza kokulawula ngesandla i-drive. Iivalvu ezisebenza ngesandla zibizwa ngokuba ziivalve zemanuwali. Ivalve ethintela ukuphuma ngasemva ibizwa ngokuba yi-check valve; lowo ulawula uxinzelelo loncedo ubizwa ngokuba yivalve yokhuseleko okanye ivalve yoncedo lokhuseleko.
Ukuza kuthi ga ngoku, ishishini levalvu liye lakwazi ukuvelisa uluhlu olupheleleyo lweiivalve zesango, iivalve zeglowubhu, iivalvu zeglowubhu, iivalve zeplagi, iivalve zebhola, iivalve zombane, iivalve zokulawula idiaphragm, iivalve zokujonga, iivalvu zokhuseleko, iivalvu zokunciphisa uxinzelelo, izibatha zomphunga kunye nezivalo zokuvala ngokukhawuleza. Iimveliso zeValve zeendidi ezili-12, iimodeli ezingaphezu kwama-3000, kunye neenkcukacha ezingaphezu kwe-4000; olona xinzelelo luphezulu lokusebenza yi-600MPa, ubukhulu bomthamo we-5350mm, ubushushu obuphezulu bokusebenza yi-1200℃, ubuncinci beqondo lokushisa ngu-196℃, kwaye i-medium esebenzayo ngaManzi, umphunga, ioli, igesi yendalo, imidiya eyomeleleyo edlayo (efana ne-nitric acid concentrated, medium concentration sulfuric acid, njl.).
Nika ingqalelo kukhetho lwevalvu:
1. Ukuze kuncitshiswe ubunzulu bogquma umhlaba wombhobho,ivalve yebhabhathaneikhethwa ngokubanzi kumbhobho omkhulu wedayamitha; eyona nto ingathandekiyo yevalve yebhabhathane kukuba i-butterfly plate ithatha icandelo elithile lomnqamlezo wamanzi, okwandisa ukulahleka kwentloko ethile;
2. Iivalvu eziqhelekileyo zibandakanyaiivalve butterfly, iivalve zesango, iivalve zebhola kunye neeplagi zeplagi, njl. Uluhlu lwee-valve ezisetyenziswe kuthungelwano lwamanzi kufuneka ziqwalaselwe ekukhethweni.
3. Ukuphoswa kunye nokucutshungulwa kweevalve zebhola kunye neeplagi zeplagi zinzima kwaye ziyabiza, kwaye zifanelekile ngokubanzi kwimibhobho encinci kunye nephakathi. I-valve yebhola kunye ne-valve yeplagi igcina inzuzo ye-valve yesango elilodwa, ukuxhathisa ukuhamba kwamanzi amancinci, ukutywinwa okuthembekileyo, isenzo esiguquguqukayo, ukusebenza kakuhle kunye nokugcinwa. I-valve yeplagi nayo ineenzuzo ezifanayo, kodwa icandelo lokudlula amanzi alikho isangqa esipheleleyo.
4. Ukuba inempembelelo encinci kubunzulu bomhlaba wokugubungela, zama ukukhetha i-valve yesango; umphakamo wevalve yesango yombane enkulu-idiameter yesango yombane ethe nkqo ichaphazela ubunzulu bogqumathelo bomhlaba bombhobho, kwaye ubude bevalve yesango ethe tye enobubanzi obukhulu kwandisa ummandla othe tye obanjwe ngumbhobho kwaye kuchaphazela ulungiselelo lweminye imibhobho;
5. Kwiminyaka yakutshanje, ngenxa yokuphucula iteknoloji yokuphosa, ukusetyenziswa kwe-resin sand casting kunokuphepha okanye ukunciphisa ukucutshungulwa komatshini, ngaloo ndlela kuncitshiswe iindleko, ngoko ke ukufaneleka kweevalve zebhola ezisetyenziswe kwimibhobho yobubanzi obukhulu kuyafaneleka ukuhlola. Ngokubhekiselele kumgca wokusikwa kwesayizi ye-caliber, kufuneka ithathelwe ingqalelo kwaye ihlulwe ngokwemeko ethile.
