Ngaba iValve yokuShutha iyafana neValve yokuKhetha?
2024-10-08Xa kuziwa kwiinkqubo zamanzi, ukuqonda amacandelo abandakanyekayo kubalulekile ekusebenzeni okusebenzayo kunye nokugcinwa. Phakathi kwezi zixhobo, i-shuttle valves kunye neevalve zokukhetha zihlala zixoxwa. Nangona zisenokubonakala zifana xa uqala nje, zenza iinjongo ezahlukeneyo kwaye zisebenza ngeendlela ezahlukeneyo. Kule blog, siza kuphonononga umahluko phakathiiivalve zesivalokunye neevalvu zokukhetha, usetyenziso lwazo, kunye nokubaluleka kwazo kwiinkqubo zamanzi.
Yintoni iValve yokuShutha?
Ivalve yesivalo luhlobo lwevalve esebenza ngoxinzelelo lwendalo evumela ulwelo ukuba luhambe ukusuka komnye wemithombo emibini ukuya kwimveliso enye. Isebenza ngokuzenzekelayo ngokusekelwe kuxinzelelo lwamanzi angenayo. Xa ulwelo lunikezelwa kwelinye lamazibuko okungena, ivalve yesivalo iyatshintsha ukuze ivumele ukuhamba ukusuka kwela zibuko ukuya kwimveliso, ivalela ngokufanelekileyo elinye izibuko. Lo matshini uqinisekisa ukuba inkqubo inokuqhubeka isebenza nokuba enye yemithombo yamanzi iyasilela.
Iimpawu eziphambili zeeValve zeShuttle
1.Ukusebenza okuzenzekelayo: Iivalve zokushutha azifuni ukungenelela ngesandla. Batshintsha ngokuzenzekelayo phakathi kwemithombo yamanzi esekelwe kuxinzelelo.
2.Imveliso enye: Zenzelwe ukwalathisa ulwelo ukusuka komnye wemithombo emibini ukuya kwisiphumo esisodwa, okubenza balungele ukuphinda-phinda kwiinkqubo zamanzi.
3.Uyilo oluQiniselekileyo: Iivalve zokushutha ziqhelekile, zivumela ukudibanisa lula kwiisekethe ezahlukeneyo ze-hydraulic.
Yintoni iValve yokukhetha?
Ngokwahlukileyo, ivalve yokukhetha luhlobo lwevalve evumela umqhubi ukuba akhethe ngesandla ukuba yeyiphi imithombo yamanzi emininzi eya kubonelela ngemveliso. Ngokungafaniyo nevalve ye-shuttle, i-valve yokukhetha idinga igalelo lomntu ukutshintsha indlela yokuhamba.
Iimpawu eziphambili zeeVave zokukhetha
1.Ukusebenza ngesandla: Iivalvu zokukhetha zisebenza ngesandla, zivumela umsebenzisi ukuba akhethe umthombo ofunekayo wolwelo.
2.Iziphumo ezininzi: Bangakwazi ukuqondisa ulwelo ukusuka kumthombo omnye ukuya kwiziphumo ezininzi okanye ukusuka kwimithombo emininzi ukuya kwimveliso enye, kuxhomekeke kuyilo.
3.Ukuguquguquka: Izivalo zomkhethi zisoloko zisetyenziswa kwizicelo apho umqhubi ufuna ulawulo lokuhamba kolwelo, njengakumatshini onemisebenzi emininzi yehydraulic.
Umahluko phakathi kweeValufa eziShuttle kunye neeValve zokuKhetha
Ukusebenza
Umahluko ophambili phakathi kweevalve ze-shuttle kunye ne-valve yokukhetha ilele ekusebenzeni kwazo. Iivalve zokushutha ngokuzenzekelayo zitshintshela phakathi kwemithombo yamanzi esekelwe kuxinzelelo, ukubonelela ngendlela yokusilela. Ngokwahlukileyo, iivalvu zokukhetha zifuna ukusebenza ngesandla, ukunika ulawulo lomsebenzisi phezu komthombo wolwelo osetyenziswayo.
Usetyenziso
Iivalve ezishuthayo ziqhele ukusetyenziswa kwiinkqubo apho ukuphindaphindwa kwemfuneko kubalulekile, njengakwiisekethe zehydraulic zenqwelomoya okanye oomatshini abanzima. Iivalve zokukhetha, kwelinye icala, zihlala zifumaneka kwizicelo ezifuna ulawulo lwabaqhubi, njengezixhobo zokwakha okanye oomatshini boshishino abanemisebenzi emininzi yehydraulic.
Ukuntsonkotha
Iivalve ze-shuttle zivame ukuba lula kuyilo kunye nokusebenza, ngelixa i-valve yokukhetha inokuba nzima ngakumbi ngenxa yeemfuno zabo zokukhethwa kwezandla kunye nokukwazi ukukhupha ezininzi.
Ukuqukumbela
Isishwankathelo, ngelixa i-shuttle valves kunye neevalve zokukhetha zingabonakala zifana, zikhonza iinjongo ezihlukeneyo kwiinkqubo ze-hydraulic. Iivalve ezishuthayo zibonelela ngokutshintsha ngokuzenzekelayo phakathi kwemithombo yamanzi ukuze kuncitshiswe kwakhona, ngelixa iivalve zokukhetha zibonelela ngolawulo lwezandla phezu kokuhamba kwamanzi. Ukuqonda lo mahluko kubalulekile ekukhetheni i-valve efanelekileyo kwizicelo ezithile ze-hydraulic, ukuqinisekisa ukusebenza kakuhle kunye nokuthembeka ekusebenzeni kwenkqubo. Nokuba uyila isekethe entsha ye-hydraulic okanye ugcina ekhoyo, ukwazi ixesha lokusebenzisa uhlobo ngalunye lwesivalo kunokwenza umahluko omkhulu ekusebenzeni okusebenzayo.
