Intshayelelo yokuKhangela iivalvu

Iivalvu zokukhangela zizivalo ezizenzekelayo ezivula ngokuqukuqela ukuya phambili kwaye zivale ngokubuyela umva.

Uxinzelelo lolwelo oludlula kwisistim luvula ivalve, ngelixa nakuphi na ukuguqulwa kokuhamba kuya kuvala ivalve. Ukusebenza ngokuthe ngqo kuya kwahluka ngokuxhomekeke kuhlobo lwendlela yokuHlola isivalo. Uninzi lweentlobo eziqhelekileyo ze-Check valves zi-swing, lift (piston kunye nebhola), ibhabhathane, i-stop and tilting-disk.

Iintlobo zeCheck valves

Ujingi Khangela ivalve
Isiseko sokujingi Khangela ivalve inomzimba wevalve, ibhonethi, kunye nediski edityaniswe kwihenjisi. I-disk ijika isuka kwisitulo sevalve ukuze ivumele ukuqukuqela ukuya kwicala eliya phambili, ize ibuyele kwisitulo sevalvu xa kunqunyanyiswa ukuqukuqela komlambo, ukuthintela ukuqukuqela ngasemva.

I-disc kuhlobo lokujingi Khangela ivalve ayilawulwa njengoko ivula okanye ivala ngokupheleleyo. Zininzi iidiski kunye noyilo lwezihlalo ezikhoyo, ukuze kuhlangatyezwane neemfuno zezicelo ezahlukeneyo. I-valve ivumela ukuhamba okupheleleyo, okungathintekiyo kwaye ivale ngokuzenzekelayo njengoko uxinzelelo luyancipha. Ezi zivalo zivaliwe ngokupheleleyo xa ukuhamba kufikelela kwi-zero, ukwenzela ukuthintela ukubuya ngasemva. I-turbulence kunye nokuhla koxinzelelo kwivalve kuphantsi kakhulu.

Lift Khangela ivalve
Uyilo lwesihlalo sevalve yokuphakamisa-Khangela iyafana nevalve yeGlobe. I-disc idla ngokufana nepiston okanye ibhola.

Iivalvu zokuPhakamisa zifanelekile ngokukodwa kwinkonzo yoxinzelelo oluphezulu apho isantya sokuhamba siphezulu. Kwilifu Khangela iivalvu, idiski ikhokelwa ngokuchanekileyo kwaye ingena ngokugqibeleleyo kwideshpot. Iivalvu zokuPhakamisa zifanelekile ukufakwa kwimigca yepayipi ethe tye okanye ethe nkqo kunye nokunyuka okunyukayo.

Ukuqukuqela ukunyusa Khangela iivalvu kufuneka zisoloko zingena ngaphantsi kwesitulo. Njengoko ukuhamba kungena, ipiston okanye ibhola iphakanyiswa ngaphakathi kwezikhokelo ukusuka esihlalweni ngoxinzelelo lokunyuka okunyukayo. Xa ukuhamba kuyeka okanye ukubuyisela umva, ipiston okanye ibhola inyanzeliswa kwisihlalo sevalve ngokubini kokubuyela umva kunye nomxhuzulane.
