Imozulu yaseTshayina ngoku ijike yaba pholileyo, kodwa imisebenzi yemveliso yeJinbin Valve Factory isahlala inomdla. Kutshanje, umzi-mveliso wethu uye wagqiba ibhetshi yee-odolo ze-iron ductile softiivalve zesango lokutywina, ezipakishweyo zaza zathunyelwa kwindawo ekuyiwa kuyo.

Umgaqo osebenzayo we-ductile iron soft sealivalufa yesango le wedgeisekelwe kuyilo olukhethekileyo kunye nezinto ezisetyenzisiweyo. Inxalenye ephambili yale valve yisango, elihlanganiswe kwirubha ekhethekileyo iyonke. Ngexesha lokusebenza, isiqu sevalve siyajikeleziswa ukuhambisa isango phezulu nasezantsi, ngaloo ndlela kunqunyulwa okanye kudityaniswe ulwelo olukumbhobho. Iindawo ezimbini zokutywinwa kwesango zihlala zenza i-wedge shape, kwaye ubukhulu be-angle ye-wedge buyahluka ngokuxhomekeka kwiiparamitha zevalve. Xa isango livaliwe, i-rubber material iya kubambelela ngokuqinileyo kwisitulo se-valve ngenxa ye-deformation elastic, ukufezekisa ukutywinwa kunye nokuvuza kwe-zero.

Ukusetyenziswa kwezinto zentsimbi ye-ductile kunika iimpawu ezintle zoomatshini kunye nokumelana nokubola, ngelixa iteknoloji yokutywina ethambileyo iqinisekisa ukusebenza kokutywinwa kunye nobomi obude benkonzo yevalve. Ukongeza, umzantsi womzimba wevalve we-ductile iron soft sealiivalvu zesango lamanziidla ngokuyilwa ngomphantsi osicaba ukuphepha ukuqokelelwa kobutyobo, ukunciphisa izinga lokungaphumeleli kokuvula nokuvala, kunye nokuqinisekisa ukuhamba kakuhle kolwelo. I-valve stem idla ngokuyilwa ngamatywina amathathu e-O-ring ukunciphisa ukuxhathisa i-frictional ngexesha lokutshintsha, ukuqinisekisa ukusebenza lula kwaye akukho kuvuza kwamanzi.

Iimeko zesicelo se-ductile iron soft sealiivalvu zesango ezomeleleyokubomi bemihla ngemihla kubandakanya kodwa akuphelelanga nje kule miba ilandelayo:

1. Inkqubo yonikezelo lwamanzi: Izivalo zesango ezitywiniweyo ezithambileyo zingasetyenziswa kwimibhobho yonikezelo lwamanzi kwisakhiwo sokuhlala nesorhwebo ukulawula uphazamiseko noqhagamshelo lokuhamba kwamanzi, ukuqinisekisa ukhuseleko nokuthembeka kwenkqubo yonikezelo lwamanzi.

2. Ukucocwa kogutyulo: Kwimizi-mveliso yogutyulo lwelindle ezidolophini kunye neenkqubo zokuhambisa amanzi amdaka, iivalvu zesango ezitywiniweyo ezithambileyo zisetyenziselwa ukulawula nokulawula ukuhamba kwamanzi amdaka, ukuthintela ukuvuza kwamanzi amdaka, nokugcina ucoceko lokusingqongileyo.

3. Ulwakhiwo: Ekwakhiweni, iivalvu zesango ezitywiniweyo ezithambileyo zingasetyenziselwa ukuqhagamshela nokuqhawula imibhobho yethutyana, kube lula ukulawula ukuhamba kwamanzi ngexesha lenkqubo yokwakha.

4. Inkqubo yokhuseleko lomlilo: Kwinkqubo yokucima umlilo yokutshiza ngokuzenzekelayo, iivalvu zesango ezitywiniweyo ezithambileyo zisetyenziselwa ukungenelela kunye nokulawula isimo kumbhobho oyintloko ukuqinisekisa ukunikezelwa kwamanzi omlilo ngexesha elifanelekileyo.

5. Unkcenkceshelo lwezolimo: Kwiinkqubo zokunkcenkceshela kwimihlaba yeefama, izivalo zesango ezitywiniweyo ezithambileyo zingasetyenziselwa ukulawula ukuhamba kwamanzi kunye nokwandisa ukusebenza kakuhle kobutyebi bamanzi.

6. Ukusetyenziswa kwamashishini: Kwezinye iinkqubo zoshishino, ezifana nokulungiswa kokutya, ukuveliswa kwamayeza, njl., iivalvu zesango elithambileyo zisetyenziselwa ukulawula ngokuchanekileyo ukuhamba kwamanzi, ukuqinisekisa umgangatho wemveliso kunye nokhuseleko lwemveliso.

Ivalve yesango lentsimbi ethambileyo etywiniweyo inokuqinisekisa ukusebenza okuqhelekileyo kweenkqubo zemibhobho kunye nokuphucula ukhuseleko lobunjineli, izenze zibe luhlobo lwevalvu ekhethwayo kwiinkqubo zokulawula ulwelo. Ukuba unazo naziphi na iimfuno ezifanelekileyo, nceda uqhagamshelane nathi ngezantsi kwaye uya kufumana impendulo kwiiyure ezingama-24.
