1.Esiqhelokhangela iivalvefezekisa kuphela ukuvalwa kwe-unidirectional kwaye uvule ngokuzenzekelayo kwaye uvale ngokusekelwe kumahluko woxinzelelo we-medium. Abanawo umsebenzi wokulawula isantya kwaye bathambekele ekubeni neempembelelo xa zivaliwe. I-valve yokukhangela amanzi yongeza i-design anti-hammer evala ngokukhawuleza kwisiseko somsebenzi wokusika. Ngokusebenzisa isixhobo esizinikezeleyo ukulawula isantya sokuvala sediski yevalve, inokunciphisa impembelelo yehamile yamanzi ngexesha lokubuyela umva kwaye ikhusele izixhobo zenkqubo. (Umfanekiso: DN1200).ivalve yetshekhi ethambekileyo enehamile yobunzima）

2.Iyantlukwano kulwakhiwo lwesakhiwo

I-valve yokuhlola eqhelekileyo inesakhiwo esilula, esiquka umzimba we-valve, i-disc, isihlalo se-valve kunye ne-reset mechanism (intwasahlobo okanye i-gravity). Ukuvulwa kunye nokuvalwa kwayo kuxhomekeke ngokupheleleyo kwi-thrust ye-medium. Ivalve yokujonga i-micro-resistance evala ngokucothayo ixhotyiswe ngendlela yokulawula ukuvala kancinane (njenge-hydraulic damping kunye ne-spring buffer components) kwesi siseko, esinokuvala ngezigaba (okokuqala vala ngokukhawuleza i-70% -80%, kwaye emva koko uvale ngokucothayo inxalenye eseleyo).

(Umfanekiso: DN700 ivalve yetshekhi yokuthamba enehamile yobunzima)

3.I-Fluid Resistance kunye noLawulo lwehamile yamanzi

Ngenxa yokulinganiselwa kwesakhiwo, i-valve yokuhlola eqhelekileyo inokumelana nokuhamba phambili okukhulu kunye nesantya sokuvala ngokukhawuleza (i-0.5 ukuya kwi-1 yesibini), enokuthi ibangele lula isando samanzi esinamandla, ngakumbi ukubeka ingozi enkulu kwiinkqubo zoxinzelelo kunye nokuhamba okuphezulu. I-valve yokukhangela i-butterfly iyanciphisa ukuchasana kwangaphambili (okt, "i-micro-resistance") ngokusebenzisa idizayini elungelelanisiweyo kwaye yandisa ixesha lokuvala ukuya kwi-3-6 imizuzwana, enokulawula isando samanzi esiphezulu ngaphakathi kwe-1.5 amaxesha oxinzelelo olusebenzayo kunye nokunciphisa kakhulu impembelelo.

4.Iimeko ezahlukeneyo ezifanelekileyo

Iivalve zokujonga eziqhelekileyo zifanelekile kwiimeko ezinoxinzelelo oluphantsi (≤1.6MPa), ukuhamba okuncinci (ububanzi bombhobho ≤DN200), kunye nokungakhathali kwihamile yamanzi, njengemibhobho yesebe yokubonelela ngamanzi asekhaya kunye neendawo zokufudumeza ezincinci zamanzi. I-valve ye-micro-resistance evala ngokucothayo engabuyiyo ifanelekile kwi-high-pressure (≥1.6MPa) kunye ne-flow-flow enkulu (ubukhulu bombhobho ≥DN250) iinkqubo, ezifana nokunikezelwa kwamanzi omlilo wesakhiwo esiphakamileyo, iindawo ezinkulu zempompo, iinkqubo zamanzi ezijikelezayo kwimizi-mveliso kunye nezinye iimeko ezibalulekileyo.

5.Ukugcinwa kunye neendleko

Iivalve zokujonga eziqhelekileyo azikho izixhobo eziyinkimbinkimbi, zinezinga eliphantsi lokungaphumeleli, kulula ukuzigcina kwaye zineendleko eziphantsi. Ngenxa yobukho bomatshini wokuvala kancinane, ivalve yokujonga ukucotha-ukuvala kancinci inokudibana neengxaki ezinje ngokumanzisa ukuvuza kweoyile kunye nokuguga kwentwasahlobo, okukhokelela kugcino oluphezulu kunye neendleko. Nangona kunjalo, ngokuqwalasela umsebenzi wokukhusela inkqubo jikelele, inikezela ngeendleko ezingcono zokusebenza kwiimeko ezinzima.

Ke ngoko, umahluko ophambili phakathi kwezi zimbini zixhomekeke ekubeni zinokuvalwa kancinci kwe-anti-hammer function: iivalvu eziqhelekileyo zokujonga i-valufa zijolise ekuvaleni, ngelixa i-micro-resistance evala ngokucothayo i-valve yokujonga i-valves ifezekisa ukuchasana okuphantsi kunye nokumelana nokothuka ngokulungiswa kwesakhiwo, kubenza babe lolona khetho lukhethwayo kwiinkqubo zoxinzelelo oluphezulu kunye nokuhamba okuphezulu.

Njengomvelisi wevalve onamava angama-20 eminyaka, i-Jinbin Valve isoloko iqinisekisa umgangatho weemveliso kunye neenkonzo zayo. Ukuba unazo naziphi na iimfuno ezinxulumeneyo, nceda uqhagamshelane nathi ngezantsi kwaye uya kufumana impendulo kwiiyure ezingama-24!
