1.0 Umahluko Phakathi kweeValve zeSango ze-OS&Y kunye neeValve zeSango ze-NRS

Izinto eziqhele ukubonakala kwiivalvu zesango yivalvu yesango elinyukayo kunye nevalvu yesango lesango elinganyukiyo, ezifana ngazo, oko kukuthi:

(1) Iivalvu zesango zivala ngokudibanisa phakathi kwesihlalo sevalvu kunye nediski yevalvu.

(2) Zombini ezi ntlobo zeevalvu zesango zinediski njengento yokuvula neyokuvala, kwaye intshukumo yediski ihambelana ngqo necala lolwelo.

(3) Iivalvu zesango zinokuvulwa ngokupheleleyo okanye zivalwe ngokupheleleyo kuphela, kwaye azinakusetyenziselwa ukulawula okanye ukubhoboza.

Ngoko ke, yintoni umahluko phakathi kwazo?I-TWSiza kuchaza umahluko phakathi kweevalvu zesango lesiqu ezinyukayo kunye neevalvu zesango lesiqu ezinganyukiyo.

Ivalvu yeSango le-OS&Y

Ukujikeleza ivili lesandla kuqhuba isiqu sevalvu enemisonto phezulu okanye ezantsi, ishukumisa isango ukuba livule okanye livale ivalvu.

Ivalvu yeSango le-NRS

Ivalvu yesango le-Non-Rising Stem (NRS), eyaziwa ngokuba yivalvu yesango le-stem ejikelezayo okanye ivalvu yesango le-stem wedge enganyukiyo, ine-stem nut efakwe kwidiski. Ukujikeleza ivili lesandla kuguqula i-valve stem, ephakamisa okanye ehlisa idiski. Ngokwesiqhelo, umsonto we-trapezoidal ucutshungulwa kwisiphelo esisezantsi sesiqu. Lo msonto, osebenzisana nomjelo wesikhokelo kwidiski, uguqula intshukumo yokujikeleza ibe yintshukumo ethe tye, ngaloo ndlela uguqula i-torque yokusebenza ibe ngamandla okutyhala.

Uthelekiso lweeValve zeSango ze-NRS kunye ne-OS&Y kwiSicelo:

1. Ukubonakala kweStem: Istem sevalvu yesango le-OS&Y sibonakala ngaphandle kwaye siyabonakala, ngelixa esevalvu yesango le-NRS sivalelwe ngaphakathi komzimba wevalvu kwaye asibonakali.
2. Indlela Yokusebenza: Ivalvu yesango le-OS&Y isebenza ngokusebenzisa uthungelwano olunemisonto phakathi kwesiqu kunye nevili lesandla, oluphakamisa okanye oluhlisa i-stem kunye ne-disc assembly. Kwivalvu ye-NRS, ivili lesandla lijika isiqu, esijikeleza ngaphakathiidiski, kwaye imisonto yayo idibana ne-nut kwidiski ukuze iyinyuse okanye ihle.
3. Isalathisi sendawo: Imisonto yokuqhuba yevalvu yesango le-NRS ingaphakathi. Ngexesha lokusebenza, isiqu sijikeleza kuphela, okwenza ukuqinisekiswa okubonakalayo kwesimo sevalvu kungenzeki. Ngokwahlukileyo koko, imisonto yevalvu yesango le-OS&Y ingaphandle, nto leyo evumela ukuba indawo yediski ibonwe ngokucacileyo nangokuthe ngqo.
4. Imfuneko Yesithuba: Iivalvu zesango le-NRS zinoyilo oluncinci ngakumbi olunokuphakama okungaguqukiyo, olufuna indawo encinci yokufaka. Iivalvu zesango le-OS&Y zinokuphakama okukhulu xa zivuliwe ngokupheleleyo, nto leyo ebangela ukuba kubekho indawo ethe nkqo ngakumbi.
5. Ukugcinwa kunye nokusetyenziswa: Isiqu sangaphandle sevalvu yesango le-OS&Y senza kube lula ukugcinwa kunye nokuthambisa. Imisonto yangaphakathi yevalvu yesango le-NRS kunzima ukuyilungisa kwaye isengozini yokukhukuliseka ngqo kwemidiya, nto leyo eyenza ukuba ivalvu ibe semngciphekweni wokonakala. Ngenxa yoko, iivalvu zesango le-OS&Y zinoluhlu olubanzi lokusetyenziswa.

Uyilo lwesakhiwo sevalvu yesango le-OS&Y kunye neevalvu zesango le-NRS zihlelwe ngolu hlobo lulandelayo:

1. Ivalvu yeSango le-OS&Y:I-valve stem nut ikwisigqubuthelo sevalvu okanye kwibracket. Xa uvula okanye uvala idiski yevalvu, ukuphakamisa okanye ukwehlisa i-valve stem kuphunyezwa ngokujikelezisa i-valve stem nut. Olu lwakhiwo luluncedo ekuthambiseni i-valve stem kwaye lwenza indawo yokuvula nokuvala ibonakale ngokucacileyo, yiyo loo nto isetyenziswa kakhulu.
2. Ivalvu yeSango le-NRS:I-nut yesiqu sevalvu ikwindawo engaphakathi emzimbeni wevalvu kwaye idibana ngqo nesixhobo sombane. Xa uvula okanye uvala idiski yevalvu, isiqu sevalvu siyajikeleziswa ukuze kufezekiswe oku. Inzuzo yale sakhiwo kukuba ukuphakama kwevalvu yesango kuhlala kungatshintshi, ngoko ke ifuna indawo encinci yokufaka, nto leyo eyenza ifaneleke kwiivalvu ezinkulu okanye iivalvu ezinesithuba esilinganiselweyo sokufaka. Olu hlobo lwevalvu kufuneka luxhotyiswe ngesalathisi esivulekileyo/esivaliweyo ukubonisa indawo yevalvu. Ingxaki yale sakhiwo kukuba imisonto yesiqu sevalvu ayinakuthambisa kwaye ivezwa ngqo kwisixhobo sombane, nto leyo eyenza ukuba yonakale.

Isiphelo

Ngamafutshane, iingenelo zeevalvu zesango elinyukayo zisekulula ukuzijonga, ukugcinwa okulula, kunye nokusebenza okuthembekileyo, okwenza zixhaphake ngakumbi kwiindlela ezisetyenziswa rhoqo. Kwelinye icala, iingenelo zeevalvu zesango elinyukayo ezinganyukiyo bulwakhiwo lwazo oluncinci kunye noyilo olugcina indawo, kodwa oku kuza ngexabiso lokungaguquguquki kunye nokulula kokugcinwa, ngoko ke zihlala zisetyenziswa kwiimeko ezinemida ethile yendawo. Xa ukhetha, kufuneka ukhethe ukuba loluphi uhlobo lwevalvu yesango oza kuyisebenzisa ngokusekelwe kwindawo ethile yokufaka, iimeko zolondolozo, kunye nendawo yokusebenza. Ukongeza kwindawo yayo ephambili kwicandelo leevalvu zesango, i-TWS ikwabonakalise ubuchule obuqinileyo bobuchwephesha kwiindawo ezininzi ezifanaiivalvu zebhabhathane, iivalvu zokujongakunyeiivalvu zokulinganisela. Singakunceda ukhethe uhlobo olufanelekileyo kwisicelo sakho kwaye samkele ithuba lokulwenza luhambelane neemfuno zakho ngqo. Siza kunika inkcazo eneenkcukacha ngakumbi ngomahluko phakathi kweevalvu zesango lesiqu esinyukayo nesinganyukiyo kwicandelo lethu elilandelayo. Hlala ubukele.
