Muva nje, e-Jinbin Valve workshop, amavalvu amabili amakhulu kagesi anezindlela ezintathu anezincazelo ze-DN1400 kanye nezinto ze-Q235B aqede ukuhlolwa kwefektri kwenqubo ephelele futhi alungele ukulethwa kumakhasimende. Lawa mavalvu adlule ukuhlolwa okuqinile kwengcindezi ye-hydrostatic ngaphandle kokuvuza kuyo yonke indawo, futhi ama-actuator kagesi asebenza kahle ngemva kokuqaliswa. Njengamanje, aqedwa ngokubukeka okuningiliziwe ukuqinisekisa ukuthi asetshenziswa esimweni sekhwalithi ephezulu.

Le valve kagesi enezindlela ezintathu iyithuluzi lokulawula eliyinhloko elenzelwe ngokukhethekile izinhlelo zokudlulisa uketshezi olukhulu. Umzimba oyinhloko wenziwe ngensimbi yekhabhoni ye-Q235B, enezici ezinhle kakhulu zesakhiwo, ukumelana nokushayisana kanye nomthamo wokuthwala ingcindezi. Ifanele izimo zokusebenza ze-DN1400 ezinobubanzi obukhulu, ihlangabezana nezidingo zokudlulisa ukugeleza okukhulu ezimweni ezifana nokuhlinzekwa kwamanzi kanye nokuphuma kwamanzi, amanethiwekhi amapayipi kamasipala, kanye namanzi ajikelezayo ezimbonini. Ivalvu isebenzisa isakhiwo sokuvala esinobubanzi obuthathu, kanti indawo yokuvala yenziwe ngezinto ezingagugi futhi ezingagqwali, ezingagcini nje ngokunciphisa ukuguguleka ngesikhathi sokuvulwa nokuvalwa, kodwa futhi zifeza ukusebenza kokuvala okuzinzile isikhathi eside, zigcina ukuvala okuthembekile ngisho nangaphansi kwengcindezi ephezulu kanye nezimo zokucindezela okukhulu. Ifakwe ama-actuator kagesi asebenza kahle kakhulu, isekela kokubili ukulawula okuzenzakalelayo okukude kanye nezindlela zokusebenza ngesandla endaweni, ivumela ukushintsha okunembile, ukuhlangana kanye nokushintshana kokugeleza kwamapayipi anezindlela ezintathu, ithuthukisa kakhulu ukusebenza kahle kwesistimu futhi inciphise izindleko zokusebenza ngesandla kanye nokugcinwa.

Esigabeni sokuhlolwa kwefektri, ithimba lobuchwepheshe lilandela ngokuqinile amazinga embonini ukuze lenze izivivinyo zokuvala ama-hydrostatic kuma-valve, ngaphandle kokuvuza noma ukuguqulwa kwawo wonke, futhi ukusebenza kokuvala kuhlangabezana nezinga lokuvuza okungaphumi. Ngesikhathi esifanayo, kwenziwa imijikelezo eminingi yokuvula nokuvala kuma-actuator kagesi ukuqinisekisa ngokugcwele ukunemba kwawo kokushaywa, isivinini sokuphendula, umkhawulo wokuvikela kanye nemisebenzi yokuvikela ngokweqile, ukuqinisekisa ukusebenza okuzinzile ngaphansi kwezimo zokusebenza eziyinkimbinkimbi. Esigabeni sokuqeda ukubukeka, abasebenzi benza ukuhlolwa okuphelele, ukugaya nokupenda kabusha imininingwane efana nokugqoka komzimba we-valve, ubuso bokuvala i-flange, kanye namabhulokhi e-actuator terminal, ukuqinisekisa ukuthi kokubili ukubukeka nokusebenza komkhiqizo kuyahlangabezana nezindinganiso, futhi kwanelisa izidingo zamakhasimende eziqinile zemishini yezimboni esezingeni eliphezulu.

Njengoba kunezinzuzo eziyinhloko ezifana nokuhamba kobubanzi obukhulu, ukushintsha okuguquguqukayo kanye nokulawula okuzenzakalelayo, amavalvu ebhabhathane kagesi anezindlela ezintathu asetshenziswa kabanzi ekuhlinzekweni kwamanzi kamasipala kanye nokuthuthwa kwamanzi, ukwelashwa kwendle, amanzi ajikelezayo esitshalo sikagesi, ukudluliselwa koketshezi lwamakhemikhali, i-metallurgy kanye nezimayini kanye neminye imikhakha. Ivalvu eyodwa ingathatha indawo yamavalvu ebhabhathane amaningi endabuko, yenza kube lula kakhulu ukwakheka kwephayiphi, inciphise ukusetshenziswa kwamandla esistimu kanye nezindleko zokulungisa kamuva, okwenza kube ukukhetha okuhle kokuthuthukiswa okuhlakaniphile nokusebenzayo kwezinhlelo zoketshezi ezinkulu.

(isithombe: i-DN1400 kagesi enezindlela ezintathu zokukhulisa ivalvu yebhabhathane)

Njengomkhiqizi wamavalvu onolwazi lweminyaka engama-20, i-Jinbin Valves izibophezele ekuhlinzekeni amakhasimende ngemikhiqizo yamavalvu ethembekile kanye nezixazululo ezenziwe ngokwezifiso. Ukuze uthole ulwazi olwengeziwe ngamavalvu kagesi anezindlela ezintathu ngobukhulu, noma ngezimfuneko zesimo sokusebenza ezenziwe ngokwezifiso, sicela ukhululeke ukubonisana nethimba lethu lobuchwepheshe ngezansi.
