Imisebenzi ephambili yevalvu ye-hydraulic balance yile:

I-1.Ngaphezu komthwalo oguqukayo kwi-piston kunye ne-piston rod, i-piston inokusebenza ngokuqhubekayo kwaye impazamo yokunyakaza yentonga ye-piston ingancitshiswa ibe yincinci.

2.Lawula i-piston stroke njengoko kuyimfuneko ukuze i-piston ikwazi ukulawulwa ngaphakathi kwinqanaba elithile kwaye ifezekise umsebenzi okhuselekileyo nothembekileyo.

3.Ukulawula ukuhla kunye nokuma kwentonga yepiston ukufezekisa umsebenzi okhuselekileyo nothembekileyo.

4.Ngaphezu koxinzelelo lwangaphakathi olungazinzanga lwe-fluid, luqinisekisa ukuhamba kakuhle kwamanzi.

5.Lawula i-piston yoxinzelelo lwe-stroke ngaphakathi kwinqanaba elincinci lokufezekisa ukusebenza okuzinzile kunye nokulawula okusebenzayo.

6.Ukulawula ukuhamba kunye noxinzelelo lolwelo ukufezekisa ukonga amandla.

Ngokubanzi, umsebenzi ophambili we-valve ye-hydraulic balance valve kukufezekisa ulawulo oluchanekileyo kunye nokusebenza okuzinzile kwenkqubo ye-hydraulic, ukuqinisekisa ukusebenza okukhuselekileyo kunye nokusebenza kakuhle kwe-hydraulic movable mechanism. Ukongeza, i-valve ye-hydraulic balance valve inokulawula uxinzelelo lwe-piston stroke ngaphakathi koluhlu oluncinci, ukufezekisa ukusebenza okuzinzile kunye nokulawula okusebenzayo, kunye nokugcina ukusetyenziswa kwamandla ombane ohambayo we-hydraulic.

Njengenxalenye ebalulekileyo ye-hydraulic, umgangatho wevalve ye-hydraulic balance ibaluleke kakhulu. Ngoko ke, xa usebenzisa i-valve ye-hydraulic balance valve, kufuneka ukhethe iimveliso eziqhelekileyo, ezithembekileyo ezisemgangathweni ukuqinisekisa ukusebenza okukhuselekileyo, okuzinzileyo kunye nokusebenzayo kwenkqubo ye-hydraulic.

I-valve yokulinganisa i-hydraulic yinxalenye ebalulekileyo esetyenziselwa ukulawula ukuhamba kunye noxinzelelo kwiinkqubo ze-hydraulic. Ilungisa uxinzelelo lwenkqubo ngokulungelelanisa ukuhamba kolwelo, ngaloo ndlela igcina uzinzo kunye nokuthembeka kwenkqubo. Ivalve yokulinganisa iHydraulic yenziwa ikakhulu ngumzimba wevalve, undoqo wevalvu, intwasahlobo, isitywina kunye namanye amalungu. Ngezantsi siza kwazisa umgaqo wayo wokusebenza ngokweenkcukacha.

1.Umgaqo

Umgaqo wokusebenza we-hydraulic balancing valves usekelwe kumgaqo olula womzimba: umthetho wokuhamba kwamaza. Ngokomthetho wamaza, xa ulwelo luhamba kumbhobho, uthotho lokuguquguquka kuya kwenzeka, okuya kubangela iindawo zoxinzelelo oluphezulu noluphantsi ngaphakathi kumbhobho. Ngoko ke, impembelelo yale mimandla yoxinzelelo oluphezulu kunye oluphantsi kwi-system stability kufuneka ithathelwe ingqalelo xa ulawula ukuhamba kwamanzi.

2.Isakhiwo

Ivalve yokulinganisa iHydraulic idla ngokuba nomzimba wevalvu, undoqo wevalvu, intwasahlobo kunye namatywina. Phakathi kwazo, i-valve body is a hollow metal cylindrical structure with some fixed fixed in the internal wall; undoqo wevalve sisakhiwo secylindrical esinemingxuma ethile etshintshekayo kumphezulu wayo; intwasahlobo isetyenziselwa ukuxhasa kunye nokulungelelanisa i-valve core. indawo amatywina asetyenziselwa ukuthintela ukuvuza kolwelo.

3.Inkqubo yokusebenza

Xa ulwelo luphuma kwisixokelelwano ukuya kwivalve yokulinganisa i-hydraulic, ingena ngaphakathi kwisiseko sevalve. Imingxuma emincinci kumbindi wevalvu ivula okanye ivale ngokusekwe kwimfuno yesixokelelwano, ngaloo ndlela ilawula ukuhamba kolwelo. Ngethuba le nkqubo, intwasahlobo ilungisa indawo ye-valve core ukuqinisekisa ukuba inokusabela kwiinguqu zenkqubo ngexesha elifanelekileyo.

Xa ulwelo lungena ngaphakathi kumzimba wevalve ngondoqo wevalve, ludlula kuthotho lwemingxuma kunye nemibhobho. Le mingxuma kunye nemibhobho ilungiselelwe ngokwemigaqo ethile ukuqinisekisa ukuba ulwelo lunokwenza uguquko oluzinzileyo ngexesha lokuhamba. Oku kuguquguquka kudala iindawo zoxinzelelo oluphezulu kunye noluphantsi oluchaphazela ukuzinza kwenkqubo yonke.

Ukuze kulungiswe le ngxaki, i-valve yokulinganisa i-hydraulic ithatha idizayini ekhethekileyo yesakhiwo: igumbi lomoya elihlengahlengiswayo libekwe phakathi kwesiseko se-valve kunye nentwasahlobo. Xa indawo yoxinzelelo oluphezulu lwenzeka kwinkqubo, igumbi lomoya linyanzeliswa, libangela ukuba intwasahlobo iphumle ngokufanelekileyo kwaye ilungise indawo engundoqo ye-valve ukunciphisa ukuhamba. Ngokuchasene noko, xa indawo yoxinzelelo oluphantsi lwenzeka kwinkqubo, i-cavity yomoya iya kwanda, ibangele ukuba intwasahlobo iqiniswe ngokufanelekileyo kwaye ilungelelanise indawo engundoqo ye-valve ukwandisa ukuhamba. Ngale ndlela, iivalve zokulinganisa i-hydraulic zigcina uzinzo kunye nokuthembeka kwenkqubo.

4.Isicelo

Iivalvu zokulinganisa i-hydraulic zisetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo ze-hydraulic, njengoomatshini bobunjineli, oomatshini bezolimo, iinqanawa, iinqwelomoya kunye namanye amacandelo. Zihlala zisetyenziselwa ukulawula ukuhamba kwamanzi kunye noxinzelelo lokuqinisekisa ukusebenza okufanelekileyo kunye nokhuseleko lwenkqubo.

Ngamafutshane, ivalve ye-hydraulic balance yinxalenye ebalulekileyo yehydraulic. Ilungisa uxinzelelo lwenkqubo ngokulungelelanisa ukuhamba kolwelo kwaye igcine uzinzo kunye nokuthembeka kwenkqubo. Umgaqo wayo wokusebenza usekelwe kumthetho wamaza kwaye wamkela uyilo olukhethekileyo lolwakhiwo lokusombulula impembelelo yeendawo eziphakamileyo kunye neziphantsi zoxinzelelo kwiinkqubo zokuzinza. Isetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo ze-hydraulic.
