Intsimbi engenasiciivalvu yebholaluhlobo oluqhelekileyo lwevalvu, kwaye umgaqo wayo wokusebenza usekelwe ekulinganeni phakathi komngxuma ojikelezayo ebholeni nakwisihlalo. Xa ivalvu ivuliwe, umngxuma odlulayo webhola uhambelana ne-axis yombhobho, kwaye i-medium inokugeleza ngokukhululekileyo ukusuka kwelinye icala lombhobho ukuya kwelinye icala ngomngxuma odlulayo ebholeni, kwaye indlela yolwelo igudile kwaye ukumelana kuncinci. （Ubungakanani bevalvu yeBhola yoMfanekiso yi-DN20）

Xa ivalvu yebhola yesinyithi kufuneka ivalwe, ibhola iyajikeleziswa ukuze umngxuma odlulayo ebholeni umi nkqo kwi-axis yombhobho, kwaye ibhola ivale ngokupheleleyo umbhobho, ngaloo ndlela inqande ukuhamba kombane. Uyilo lwesixhumi esiphindwe kabini lwenza ivalvu ibe lula ngakumbi xa ifakwa kwaye isuswa, kwaye inokudityaniswa ngokulula kwaye yahlulwe kumbhobho ukuze kube lula ukuyilungisa nokutshintsha.

Ivalvu yebhola engatyiwayo ye-PPR ineengenelo ezininzi:

1. Ukusebenza okulula

Kufuneka ujikeleze iidigri ezingama-90 kuphela ukuze uvuleke ngokupheleleyo okanye uvale ngokupheleleyo ivalvu, ukusebenza okulula nokukhawulezayo, kunokuphucula ukusebenza kakuhle.

2. Ukusebenza kakuhle kokutywina

Izixhobo zokutywina ezikhethekileyo kunye noyilo lwesakhiwo ziyasetyenziswa phakathi kwebhola kunye nesihlalo, nto leyo enokufezekisa isiphumo esihle sokutywina, ithintele ngokufanelekileyo ukuvuza kwemidiya, kwaye iqinisekise ukusebenza ngokukhuselekileyo kwenkqubo yemibhobho.

3.Umthamo omkhulu wokujikeleza kwegazi

Xa i-sphere ivuliwe, umjelo awuphazanyiswa, i-medium ingadlula kakuhle, inomthamo omkhulu wokuhamba, kwaye inokuhlangabezana neemfuno zokusebenza kokuhamba okukhulu.

4. Ukumelana nokugqwala okuqinileyo

Ngokweendlela ezahlukeneyo zokusasaza kunye nendawo yokusebenza, khetha izinto ezifanelekileyo, ezifana nentsimbi engagqwaliyo, ubhedu, njl.njl., ezinokumelana nokugqwala okuhle, zandise ubomi benkonzo yevalvu.

5. Ufakelo oluguquguqukayo

Uyilo lwe-duplex luvumela ukulungiswa okuguquguqukayo kwendawo yayo ngexesha lokufakelwa, okulula ukuqhagamshela kwiipayipi ezinobubanzi obahlukeneyo kunye neendawo ezahlukeneyo, okunciphisa ubunzima bokufakelwa.

I-Jinbin Valve njengomzi-mveliso wokwenza amandla eevalvu weminyaka engama-20, ukuze kwenziwe imfuno yeevalvu kwihlabathi liphela, ukuveliswa kweevalvu ezahlukeneyo ze-metallurgical ezinkulu, ukuba unemibuzo, nceda ushiye umyalezo apha ngezantsi, uya kufumana impendulo kwiiyure ezingama-24, ndilangazelela ukusebenza nawe!
