1. Eqhelekileyoiivalvu zokujongaZivala ngendlela ethe ngqo kuphela kwaye zivuleke kwaye zivale ngokuzenzekelayo ngokusekelwe kumahluko oxinzelelweyo wesixhobo. Azinawo umsebenzi wokulawula isantya kwaye zinokuba yingozi xa zivaliwe. Ivalvu yokujonga amanzi yongeza uyilo oluchasene nesando oluvala kancinci ngokusekelwe kumsebenzi wokusika. Ngokusebenzisa isixhobo esizinikeleyo ukulawula isantya sokuvala sediski yevalvu, inokunciphisa impembelelo yesando samanzi ngexesha lokuphuma kwamanzi kwaye ikhusele izixhobo zenkqubo.（Umfanekiso: DN1200ivalvu yokujonga ukuthambeka enesando sobunzima）

2. Umahluko kwisakhiwo solwakhiwo

Ivalvu yokujonga eqhelekileyo inesakhiwo esilula, esiquka umzimba wevalvu, idiski, isihlalo sevalvu kunye nendlela yokuseta kwakhona (intwasahlobo okanye umxhuzulane). Ukuvulwa nokuvalwa kwayo kuxhomekeke ngokupheleleyo ekutyhalweni kwesixhobo. Ivalvu yokujonga evala kancinci enganyangekiyo ixhotyiswe ngendlela yokulawula ukuvala kancinci (efana nokuxinana kwe-hydraulic kunye nezinto ezithintela i-spring buffer) ngesi siseko, enokuvala ngamanqanaba (okokuqala ivale ngokukhawuleza i-70%-80%, ize emva koko ivale kancinci inxalenye eseleyo).

3. Ukumelana nolwelo kunye nolawulo lwesando samanzi

Ngenxa yemida yesakhiwo, ivalvu yokujonga eqhelekileyo inokumelana okukhulu phambili kunye nesantya sokuvala esikhawulezayo (0.5 ukuya kwi-1 sec), nto leyo enokubangela ihamile yamanzi enzima, ingakumbi ukuba yingozi enkulu kwiinkqubo zoxinzelelo oluphezulu kunye nokuhamba kwamanzi aphezulu. Ivalvu yokujonga ibhabhathane iyanciphisa ukumelana phambili (oko kukuthi, "ukuxhathisa okuncinci") ngoyilo olucwangcisiweyo kwaye yandisa ixesha lokuvala ukuya kwimizuzwana emi-3-6, enokulawula ihamile yamanzi ephezulu ngaphakathi kwe-1.5 yexinzelelo lokusebenza kwaye inciphise kakhulu impembelelo.

4. Iimeko ezahlukeneyo ezifanelekileyo

Iivalvu zokujonga eziqhelekileyo zifanelekile kwiimeko ezinoxinzelelo oluphantsi (≤1.6MPa), ukuhamba kancinci (ububanzi bepayipi ≤DN200), kunye nokungakhathali kwihammer yamanzi, njengemibhobho yesebe yokuhambisa amanzi ekhaya kunye neendawo zokuphuma zezifudumezi zamanzi ezincinci. Ivalvu engabuyiyo evala kancinci ifanelekile kwiinkqubo ezinoxinzelelo oluphezulu (≥1.6MPa) kunye neenkqubo ezihamba kakhulu (ububanzi bepayipi ≥DN250), ezifana nokubonelela ngamanzi omlilo ezakhiwo eziphakamileyo, iindawo zokukhupha ezinkulu, iinkqubo zamanzi ajikelezayo kwimizi-mveliso kunye nezinye iimeko ezibalulekileyo.

5. Ulondolozo kunye neendleko

Iivalvu zokujonga eziqhelekileyo azinazo izixhobo ezintsonkothileyo, zinezinga eliphantsi lokusilela, kulula ukuzigcina kwaye zineendleko eziphantsi. Ngenxa yokubakho kwendlela yokuvala kancinci, ivalvu yokujonga evala kancinci inokujongana neengxaki ezifana nokufuma kweoyile kunye nokuguga kwentwasahlobo, okubangela ukuba kubekho ubuninzi bexesha lokugcinwa kunye neendleko. Nangona kunjalo, xa ucinga ngomsebenzi wokukhusela inkqubo iyonke, inika ukusebenza okungcono kweendleko kwiimeko ezibalulekileyo.

Ngoko ke, umahluko ophambili phakathi kwezi zimbini kukuba zinomsebenzi wokulwa nesando ovala kancinci na: iivalvu zokujonga eziqhelekileyo zigxila ekucinyweni okusisiseko, ngelixa iivalvu zokujonga ezivala kancinci zifumana ukumelana okuphantsi kunye nokumelana nokutshayiswa ngokulungiswa kwesakhiwo, nto leyo ezenza zibe lolona khetho lukhethwayo kwiinkqubo zoxinzelelo oluphezulu kunye nokuhamba kwamanzi okuphezulu.

Njengomvelisi weevalvu onamava angama-20 eminyaka, iJinbin Valve ibisoloko iqinisekisa umgangatho weemveliso kunye neenkonzo zayo. Ukuba unayo nayiphi na imfuno enxulumene noko, nceda unxibelelane nathi apha ngezantsi kwaye uya kufumana impendulo kwiiyure ezingama-24!
