1.0 Umahluko phakathi kweeValuvu zeSango le-OS&Y kunye neeValufa zeSango le-NRS

Iqhele ukubonwa kwiivalvu zesango yivalve yesango yesiqu esinyukayo kunye nevalve yesango yesiqu enganyukiyo, ezabelana ngokufana, oko kukuthi:

(1) Iivalvu zesango zitywina ngokudibana phakathi kwesitulo sevalve kunye nediski yevalvu.

(2) Zombini iintlobo zeevalve zesango zine-disc njengento yokuvula kunye nokuvala, kwaye ukuhamba kwediski kuxhomekeke kwicala lomlambo.

(3) Iivalve zesango zinokuvulwa ngokupheleleyo okanye zivalwe ngokupheleleyo, kwaye azinakusetyenziselwa ukulawulwa okanye ukungqusha.

Ngoko ke, yintoni umahluko phakathi kwabo?TWSiya kuchaza umahluko phakathi kweevalvu zesango lesikhondo esinyukayo kunye neevalvu zesango lesiqu esingaphumiyo.

Ivalufa yeSango ye-OS&Y

Ukujikeleza ivili lesandla kuqhuba isiqu sevalve enemisonto phezulu okanye ezantsi, uhambisa isango ukuze livule okanye livale ivalve.

I-Valve yeSango le-NRS

Ivalve yesango ye-Non-Rising Stem (NRS), ekwaziwa ngokuba yivalve yesango yesiqu esijikelezayo okanye ivalve yesango ye-stem wedge enganyukiyo, ine-stem nut egxunyekwe kwidiski. Ukujikeleza i-handwheel ijika i-valve stem, ephakamisa okanye ehlisa i-disc. Ngokuqhelekileyo, intambo ye-trapezoidal iqhutywe ekupheleni kwesiqu. Lo msonto, ubandakanya umjelo wesikhokelo kwi-disc, uguqula ukunyakaza okujikelezayo kwintshukumo yomgca, ngaloo ndlela uguqula i-torque yokusebenza ibe yi-thrust force.

Uthelekiso lwe-NRS kunye ne-OS&Y iiValufa zeSango kwiSicelo:

1. Ukubonakala Kwesiqu: Isiqu sevalve yesango ye-OS&Y sityhilekile ngaphandle kwaye siyabonakala, ngelixa eso valvu yesango ye-NRS ivalelwe ngaphakathi kumzimba wevalvu kwaye ingabonakali.
2. Indlela yokuSebenza: Ivalve yesango ye-OS&Y isebenza ngokudityaniswa okudityanisiweyo phakathi kwesiqu kunye nevili lesandla, eliphakamisa okanye lehlise isiqu kunye nediskhi yokudityaniswa. Kwivalve ye-NRS, ivili lesandla lijika isiqu, esijikeleza ngaphakathiidiski, kwaye imisonto yayo idibanisa ne nut kwidiski ukuyihambisa phezulu okanye ezantsi.
3. Isikhundla Isalathiso: Imisonto yokuqhuba yevalve yesango le-NRS ingaphakathi. Ngethuba lokusebenza, isiqu sijikeleza kuphela, okwenza ukuqinisekiswa okubonakalayo kwesimo se-valve akunakwenzeka. Ngokwahlukileyo, imicu yevalve yesango ye-OS & Y ingaphandle, ivumela indawo yediski ukuba ibonakale ngokucacileyo kwaye ngokuthe ngqo.
4. Imfuneko yendawo: Iivalvu zesango le-NRS zinoyilo oludityanisiweyo olunobude obungaguqukiyo, obufuna indawo yofakelo encinane. Ivalvu yesango ye-OS&Y inobude obukhulu xa ivuleke ngokupheleleyo, ifuna isithuba esithe nkqo ngakumbi.
5. Ukugcinwa kunye nokuFaka: Isiqu sangaphandle sevalvu yesango ye-OS&Y sinceda ukugcinwa lula kunye nokuthambisa. Imicu yangaphakathi yevalve yesango le-NRS inzima kakhulu kwinkonzo kwaye ichaphazeleka ngakumbi kukhukuliseko lwemidiya ngqo, okwenza ivalve ibe yingozi ngakumbi. Ngenxa yoko, iivalvu zesango le-OS&Y linoluhlu olubanzi losetyenziso.

Uyilo lolwakhiwo lwevalvu yesango ye-OS&Y kunye neevalvu zesango le-NRS zihlelwe ngolu hlobo lulandelayo:

1. Ivalve yeSango ye-OS&Y:I-valve stem nut ibekwe kwisigqubuthelo sevalve okanye isibiyeli. Xa uvula okanye uvala i-disc ye-valve, ukuphakamisa okanye ukuhla kwe-valve stem kufezekiswa ngokujikeleza i-valve stem nut. Esi sakhiwo sinenzuzo yokugcoba i-valve stem kwaye yenza indawo yokuvula kunye nokuvala ibonakale ngokucacileyo, yingakho isetyenziswa ngokubanzi.
2. Ivalve yeSango ye-NRS:I-valve stem nut ingaphakathi kumzimba wevalvu kwaye idibana ngokuthe ngqo nophakathi. Xa uvula okanye uvala i-disc ye-valve, i-valve stem iyajikelezwa ukufezekisa oku. Inzuzo yesi sakhiwo kukuba ukuphakama okupheleleyo kwevalve yesango kuhlala kungatshintshi, ngoko kufuna indawo encinci yokufakela, okwenza ukuba ifaneleke i-valve-diameter-diameter okanye i-valve eneendawo ezinqamlekileyo zokufakela. Olu hlobo lwevalve kufuneka luxhotyiswe ngesalathisi esivulekileyo / esivaliweyo ukubonisa indawo yevalve. Ukungalungi kwesi sakhiwo kukuba i-valve stem threads ayikwazi ukuthanjiswa kwaye ibonakaliswe ngokuthe ngqo kwi-medium, ibenza ukuba bahlasele umonakalo.

Ukuqukumbela

Ukubeka nje, iingenelo zokunyuka kwee-valve zamasango e-stem zilele ekubukeni kwazo ngokulula, ukugcinwa okufanelekileyo, kunye nokusebenza okuthembekileyo, okwenza kube yinto eqhelekileyo kwizicelo eziqhelekileyo. Ngakolunye uhlangothi, iingenelo zokungakhuphuki kwee-valve zesango ze-stem ziyi-compact yabo kunye noyilo lokulondoloza indawo, kodwa oku kuza kwiindleko ze-intuitiveness kunye nokulula ukugcinwa, ngoko ke zihlala zisetyenziswa kwiimeko ezinemithintelo ethile yendawo. Xa ukhetha, kufuneka wenze isigqibo sokuba yeyiphi i-valve yesango oza kuyisebenzisa ngokusekelwe kwindawo ethile yokufakela, iimeko zokugcina, kunye nendawo yokusebenza. Ukongeza kwindawo yayo ekhokelayo kwintsimi yeevalvu zesango, i-TWS ikwabonise amandla obuchule obuqinileyo kwiindawo ezininzi ezifanaiivalve butterfly, khangela iivalve, kwayeiivalve zokulinganisa. Sinokukunceda ukhethe olona hlobo lufanelekileyo lwesicelo sakho kwaye wamkele ithuba lokuyilungisa ngokweemfuno zakho kanye. Siza kunika ingcaciso ethe kratya yomahluko phakathi kwe-stem ephakamayo kunye neevalvu zesango ezingapheliyo kwicandelo lethu elilandelayo. Hla umamele.
