Kwindawo yeprojekthi yokugcina amanzi eLaos, umthengi uzithengele iivalvu zeebhabhathane ze-lug kunye neejoyinti zerabha zokwandisa iipayipi, kwaye izixhobo azizange zisebenze kakuhle emva kokwakhiwa. Umthengi uthenge iivalvu zeebhabhathane ze-DN300 lug kunye neejoyinti zokwandisa ze-DN300 ngokwahlukeneyo, ebeka iiodolo ngokwedayamitha eqhelekileyo. Ngaphandle kokubonisana neengcali zobugcisa ukuqinisekisa ubungakanani besakhiwo seemveliso, umthengi akawunakanga umahluko wangaphakathi phakathi kwezi ntlobo zimbini zeemveliso.

Emva kokufakelwa nokuqaliswa kokusebenza, kwafunyaniswa ukuba ububanzi bangaphakathi bale DN300 expansion joint buncinci kunendlela yangaphakathi ye-lug butterfly valve enobukhulu obufanayo. Xa idiski ye-butterfly valve ijikeleza, ivalwe yi-port ye-expansion joint. Idiski ye-valve ayinakuvuleka ngokupheleleyo, ngoko ke inkqubo yepayipi ayinakufakwa kwinkonzo eqhelekileyo.

I-Jinbin Valve ibonelele ngesicwangciso sokuphinda isebenze kwakhona esilandelayo: susa ivalvu yebhabhathane yokuqala ye-lug uze uyitshintshe ngevalvu yebhabhathane ye-flange ehambelana nale joint yokwandisa. Ngokwebude besakhiwo sevalvu entsha yebhabhathane, sika kwaye ulungise umbhobho okwindawo ukuze ulungelelaniswe, uze ugqibezele umsebenzi wokuqinisa i-flange phakathi kwejoint yokwandisa kunye nevalvu entsha. Inkqubo yonke yokuphinda isebenze ibandakanya ukusika imibhobho, ukususwa kwenxalenye endala, ukubeka ivalvu entsha, ukujonga i-flange centering kunye nokuvala. Le nkqubo ithatha ixesha kwaye ifuna umsebenzi omninzi, ibangela iindleko ezongezelelweyo zomsebenzi, izixhobo kunye nexesha lokwakha, kwaye ilibazisa ngokuthe ngqo inkqubela phambili yeprojekthi.

Eli tyala linika isikhumbuzo esibalulekileyo sokuthengwa kobunjineli bamanye amazwe. Xa ukhetha iivalvu zepayipi kunye neejoyinti zokwandisa ezifanayo, abathengi akufuneki bakhethe kwaye bathenge iimveliso kuphela ngobukhulu be-DN eqhelekileyo. Iivalvu zezakhiwo ezahlukeneyo (iivalvu zebhabhathane ze-lug, iivalvu zebhabhathane ze-flange) kunye neejoyinti zokwandisa zahlukile kwi-bore yangaphakathi, isakhiwo sobuso bokugqibela kunye nobude bokufakelwa nokuba zinobubanzi obufanayo.

Xa kuthengwa ubunjineli bamanye amazwe, abanini beprojekthi kufuneka bangenise iiparameter zemeko yokusebenza kuquka iinkcukacha zombhobho, uxinzelelo oluphakathi, kunye nendawo yokufakela kwiinjineli zobugcisa zabavelisi beevalvu kwangaphambili. Iingcali zobugcisa kufuneka zigqibezele ukukhetha kunye nokudibanisa uhlobo oludibeneyo. Musa ukuthenga iivalvu kunye nezixhobo zombhobho ngokwahlukeneyo kwaye uzihlanganise ngokungacwangciswanga kwindawo. Ukuthengwa kunye nokuhlanganiswa okuzimeleyo okungaboniyo kunokukhokelela ngokulula ekuphazamisekeni kwebhore, ukusilela kokuvala, ukuxinana kweediski zevalvu kunye nezinye iimpazamo, okukhokelela ekusetyenzisweni ngokutsha kunye nokuchitha ixesha kunye neendleko zeprojekthi. Unxibelelwano lobuchwephesha lobuchwephesha ngaphambi kweprojekthi ngundoqo wokuqinisekisa ukufakwa okuzinzileyo kunye nokusebenza kakuhle kwenkqubo yakho yombhobho.

Njengomvelisi weevalvu onamava angama-22 eminyaka, iJinbin Valve ivelisa iivalvu ezahlukeneyo zesinyithi kunye neevalvu zobunjineli bokugcinwa kwamanzi. Sixhotyiswe liqela lobuchwephesha lobuchwephesha, sizenzela ngokwezifiso iivalvu ngokweemeko zokusebenza kwindawo kwaye sinikezela ngezisombululo ezifanelekileyo kubathengi behlabathi. Ukuba unayo nayiphi na imfuneko, nceda unxibelelane nathi ngezantsi. Uya kufumana impendulo kwiiyure ezingama-24. Silangazelela ukusebenzisana nawe.
