IiValvu zeSango: Izisombululo ezibalulekileyo zokuvala iinkqubo zoshishino
Iivalvu zeSangozizixhobo ezibalulekileyo zokuvala kwiinkqubo zolawulo lolwelo. Ngokuphakamisa okanye ukwehlisa ipleyiti yesango, zenza kube lula ukulawula ukuhamba kwamanzi ngokuchanekileyo ngaphandle kokumelana kakhulu. Zaziwa ngokutywina kwazo okuqinileyo, uyilo olulula, kunye nokungqubana kolwelo okuphantsi, ezi valves zibaluleke kakhulu kwi-oyile/igesi, ukuvelisa umbane, ukucutshungulwa kweekhemikhali, kunye nemibhobho yokulawula amanzi.
Ukuqonda Iintlobo zeValve yeSango: Isikhokelo sokuHlela esiBanzi
Iivalvu zesango zizinto ezibalulekileyo kwiinkqubo zolawulo lolwelo, ezihlelwe ngokuyintloko ngoyilo lwazo lwesakhiwo, indlela yokutywina, uhlobo lokuqalisa, indlela yokudibanisa, kunye nezixhobo zokwakha. Esi sikhokelo sihlola ulwahlulo oluphambili ukukunceda ukhethe ivalvu efanelekileyo kwisicelo sakho.
I. Uhlulo ngokweYilo lweZakhiwo
- Iivalvu zeSango leWedge:
- I-wedge eqinileyo:Inoyilo olulula nolunenxalenye enye. Inika ukuthembeka kodwa ifuna ii-engile zomphezulu ezichanekileyo zokutywina. Ukuguquguquka kobushushu ngamanye amaxesha kunokubangela ukubopha (ukubhitya).
- I-Wedge eguquguqukayo:Ibandakanya ukusika okujikeleze umjikelezo (umngxuma we-annular), okubonelela ngokuthamba okuphuculweyo. Olu yilo luhlawulela ukwanda/ukucutheka kobushushu, luphucula ukusebenza kubushushu obahlukeneyo kunye noxinzelelo.
- I-Split Wedge (Idiski Embini):Isebenzisa iidiski ezimbini ezihleli zodwa. Oku kuvumela ukubuyiselwa ngokuzenzekelayo kokuguguleka okuncinci komphezulu, okwandisa ubomi benkonzo. Ifanelekile kakhulu kwiincindi eziphantsi kunye nenkonzo yomphunga; indlela yokusebenza iyinkimbinkimbi kunee-wedges eziqinileyo.
- Iivalvu zeSango leSilayidi ezihambisanayo:
- Uhlobo lokutywina oluzenzekelayo:Ixhomekeke kuphela kuxinzelelo oluhambelanayo ukunyanzela iidiski ezilinganayo kwizihlalo ukuze zitywinwe. Ulwakhiwo olulula noluqinileyo.
- Uhlobo lokutywina ngoomatshini (iSango elandayo):Isebenzisa indlela yokusasaza (edla ngokuba yi-wedge phakathi kweediski) enyanzela iidiski ukuba ziphume ziye ezihlalweni njengoko ivalvu ivula, nto leyo eyenza ukutywinwa okuqinisekileyo ngaphandle koxinzelelo lomgca.
- Isiqu Esinyukayo vs. Isiqu Esingavukiyo:
- Iivalvu zeSango leSitem esiKhulayo (OS&Y):Iintambo zesiqu ziphuma ngaphandle, nto leyo ebangela ukuba isiqu siphakame ngokubonakalayo siphume emzimbeni wevalvu xa sivuliwe. Ibonelela ngendlela ecacileyo yokubonakala kwaye yenza kube lula ukuthambisa/ukulungisa.
- Iivalvu zeSango leStem ezinganyukiyo (i-NRS):Isiqu singena ngaphakathi esangweni. Isiqu sijikeleza kuphela ngexesha lokusebenza, kungekho ntshukumo yokunyuka. Ilungele ukufakwa okunendawo encinci ethe nkqo (ngaphantsi komhlaba, iinkqubo ezincinci).
II. Uhlulo ngokweNdlela yokutywina
- IiValvu zeSango eziHlaliswe kamnandi: Sebenzisa izinto zokuvala eziqinileyo ezifana ne-EPDM, irabha ye-NBR, okanye i-PTFE (Teflon) kwi-interface yesihlalo/yesango. Zivale ngendlela engaqhelekanga, nokuba kuphantsi koxinzelelo. Zimelana kakhulu nokugqwala kwaye zilungele amanzi, iikhemikhali kunye neegesi apho kungekho kuvuza kubalulekileyo. Ngokubanzi azifanelekanga kumaqondo obushushu aphezulu kakhulu.
- Iivalvu zeSango eziHlalwa ngentsimbi (ezitywiniweyo kakhulu): Zinonxibelelwano lwentsimbi nentsimbi phakathi kwesango nesihlalo (umz., intsimbi engagqwaliyo kwintsimbi engagqwaliyo, ii-stellite overlays). Zenzelwe ukumelana namaqondo obushushu aphezulu, uxinzelelo oluphezulu, kunye nemidiya erhabaxa. Nangona zibonelela ngokuqina okuhle, akukho kuvuza kupheleleyo kunokuba nzima ukufikelela kuko xa kuthelekiswa noyilo oluthambileyo. Zixhaphakile kwizixhobo zomphunga, ioyile negesi, kunye nobushushu obuphezulu.
III. Uhlulo ngokweNkqubo yoBuchule
- Iivalvu zeSango ezenziwe ngesandla: Zisebenza ngevili lesandla okanye nge-lever. Isisombululo esilula nesingabizi kakhulu kwiivalvu ezifikelelekayo ezifuna ukusetyenziswa rhoqo.
- Iivalvu zeSango loMbane: Zisebenza nge-actuator yemoto yombane. Vumela ukusebenza kude, ukuhlanganiswa kokuzenzekelayo, kunye nolawulo oluchanekileyo. Kubalulekile kwiivalvu ezinkulu, kwiindawo ezinobungozi, okanye kwiinkqubo ezizenzekelayo.
- Iivalvu zeSango lePneumatic/Hydraulic: Sebenzisa umoya ocinezelweyo (pneumatic) okanye ulwelo oluxinzelelweyo (hydraulic) ukuze usebenze. Zibonelela ngemijikelo evulekayo/evaliweyo ngokukhawuleza kwaye zivelise i-torque ephezulu kakhulu, ezenza zilungele ukusetyenziswa okudinga impendulo ekhawulezileyo okanye ukuphatha uxinzelelo oluphezulu.
