Kwi-workshop yaseJinbin, elinye iqela leevalvu zesango ezitywiniweyo ezithambileyo zeflange zilungele ukuthunyelwa, kuquka nesiqu esifihliweyoivalvu yesango etywiniweyo ethambileyokunye nevalvu yesango le-flange eveziweyo, enobukhulu be-DN80 kunye ne-DN100, kwaye yenziwe ngentsimbi ephosiweyo i-QT450. Njengabasebenzi bokufumana kunye nokusebenza kunye nokugcinwa kwepayipi, ukukhetha ivalvu yesango ethambileyo ye-flange efanelekileyo ayinakususa kuphela iingozi zokuvuza kodwa inokwandisa ubomi benkonzo kwaye inciphise iindleko zokusebenza kunye nokugcinwa. Xa uthenga, akukho mfuneko yokuthelekisa amaxabiso ngokungaboni. Gxila kwiingongoma eziphambili: ukufanisa iimeko zokusebenza, izixhobo ezikumgangatho ophezulu, iinkqubo zokuvelisa ezisemgangathweni, kunye nenkonzo ethembekileyo emva kokuthengisa. Musa ukulandela amaxabiso aphantsi ngokungaboni. Kuphela ngokulinganisela umgangatho kunye nokusebenza kweendleko apho unokukhetha ivalvu yesango ethembekileyo nehlala ixesha elide.

(umfanekiso: I-Non-Rising Stem Flange Soft-Sealing Gate Valve Dn100, I-Rising Stem Flange Soft-Sealing Gate Valve Dn80) 

Okokuqala, fanisa iiparameter zemeko yokusebenza. Beka phambili ukujonga uxinzelelo lombhobho kunye nobubanzi. Kwiinkqubo zokubonelela ngamanzi ngokubanzi kunye nokukhupha amanzi kunye nokukhusela umlilo, i-1.0/1.6 MPa idla ngokwanela. Nangona kunjalo, kwiimeko zobushushu obuphezulu kunye noxinzelelo oluphezulu, inqanaba lokumelana noxinzelelo kufuneka liphuculwe. Kwangaxeshanye, chonga ngokucacileyo uhlobo lwesixhobo. Izinto ezahlukeneyo zokutywina zifanelekile kumanzi acocekileyo kunye nelindle ukuthintela ukugqwala kwezinto kunye nokuguga ngokukhawuleza. 

Okwesibini, qwalasela umgangatho womzimba wevalvu kunye nesitywino.ivalvu yesango lamanziUmzimba kufuneka wenziwe ngentsimbi ethambileyo, eqinileyo kwaye enganyangekiyo kukuguquka. Ziphephe izinto ezifakwe i-thin-shell defensive castings. I-soft seal yeyona nto iphambili. Kucetyiswa ukuba ukhethe iindawo ze-EPDM okanye ze-NBR ezibunjiweyo, ezinobungqingqwa obuhle kunye nokusebenza okuqinileyo kokuvala, ezingenako ukuvuza, kwaye zithintele iingxaki zokuvuza, ukuvuza kunye nokuvuza.

Ngaphezu koko, qwalasela isakhiwo kunye nobugcisa. Khetha isakhiwo sesiqu esifihliweyo, esithatha indawo encinci kwaye singabi namdla wokuqokelelwa kothuli kunye nokugqwala. Ubuso besiphelo seflange kufuneka bube tyaba kwaye bungabi naziphene, bube nemingxunya yebholiti elungelelaniswe kakuhle ukuze kube lula ukufaka nokudibanisa kwindawo. Isiqu sevalvu yesango lesitywino kufuneka sibe bushelelezi ngaphandle kokunamathela, okuvumela ukuvulwa nokuvalwa lula, kwaye akufuneki sibambeke nokuba sele sisetyenziswe ixesha elide.

Okokugqibela, nika ingqalelo kwiziqinisekiso kunye nenkonzo yasemva kokuthengisa. Cela iingxelo zezinto ezibonakalayo kunye nezatifikethi zokuhlola, kwaye ulahle iimveliso ngaphandle kolwazi. Beka phambili abavelisi ngenkonzo epheleleyo yasemva kokuthengisa, iziqinisekiso zomgangatho ocacileyo, kunye neempendulo ezikhawulezayo. Naziphi na iingxaki kwixesha elizayo zingasonjululwa ngokukhawuleza. I-Jinbin Valve ibisoloko ivelisa iivalvu ezikumgangatho ophezulu kangangeminyaka engama-20 (uMvelisi weeValve zeSango), kunye nomgangatho oqinisekisiweyo. Ukuba unayo nayiphi na imfuno enxulumene noko, nceda unxibelelane nathi ngezantsi. Uya kufumana impendulo kwiiyure ezingama-24!
