Kutshanje, umzi-mveliso wethu uye wagqiba ngempumelelo umsebenzi wokuvelisa i-valve ye-DN300 phantsi kwenkqubo engqongqo yokulawula umgangatho. Ziyilwe ngononophelo kwaye zenziwe ngokuchanekileyo, eziiivalvu zokujonga amanzibonisa kungekuphela nje ubuchule bethu bokulawula ulwelo, kodwa nokuzibophelela kwethu kumgangatho wemveliso. Okwangoku, zonke iivalve zokutshekisha zigqibe umsebenzi wokugqibela wokuhlola kwaye zingena kwinqanaba lokupakisha, eliza kuthunyelwa kumthengi.

Njengenxalenye ephambili kwinkqubo ye-fluid, umsebenzi oyintloko wexabiso le-valve yokutshekisha kukuthintela ukubuya kwe-medium kunye nokukhusela ukusebenza okukhuselekileyo kunye nokuzinza kwenkqubo yombhobho. Ivalve yokujonga i-DN300 eveliswe ngumzi-mveliso wethu ithatha izinto eziphambili kunye netekhnoloji, inokusebenza kakuhle kokutywina kunye nokumelana nokubola, kwaye ilungele iimeko ezahlukeneyo zokusebenza ezinzima. Uyilo lwayo olukhethekileyo luqinisekisa ukuba lunokuvalwa ngokukhawuleza naphantsi kweemeko ezihlukeneyo zoxinzelelo oluphezulu, ukuphepha ngokufanelekileyo ukwenzeka kwesiganeko sehamile yamanzi, kunye nokuqinisekisa ukhuseleko lwenkqubo yonke yepayipi.

Ivalve yokukhangela eneflangedekusebenziseni izilumkiso:

1. Utolo lubonisa indlela yokuhamba kwamanzi, kwaye ukufakela kufuneka kuqinisekise ukuba utolo lukhomba kwicala elifanayo kunye nokuhamba kwamanzi, ngaphandle koko kuya kuchaphazela ukusebenza okuqhelekileyo kwevalve.

2. Ukuze kuqinisekiswe ukusebenza okuzinzile kwexesha elide lokukhangela i-valve, kucetyiswa ukuba uhlolisise kwaye uyigcine rhoqo ngokuhambelana nencwadana yokusebenza, ngokukodwa iindawo zokugqoka ezifana ne-valve disc kunye nentwasahlobo.

3. Nangona ii-valve zethu zokuhlola eziqiniweyo zenzelwe ukuba zibe nomthamo ophezulu wokuthwala uxinzelelo, kusafuneka ukuba ugweme ukusetyenziswa okungaphezulu koxinzelelo olulinganisiweyo lokusebenza ukuphepha umonakalo.

Siyathembisa ukuba yonke ivalve yokuhlola engabuyiyo ethunyelweyo iya kuthwala ukuzibophelela kwethu kumgangatho kunye noxanduva kubathengi bethu. Kwixesha elizayo, umzi-mveliso wethu uya kuqhubeka nokubambelela kumbono "wokutsha, umgangatho, inkonzo", kunye nokuphucula rhoqo ukusebenza kwemveliso ukuhlangabezana neemfuno ezahlukeneyo zemarike. Kwangaxeshanye, sikwajonge ngethemba ekusebenzeni namaqabane amaninzi ukukhuthaza ngokudibeneyo uphuhliso nenkqubela-phambili yoshishino kunye nokudala ikamva elingcono.
