Kutshanje, kwi-workshop yeJinbin Valve, iivalvu ezimbini ezinkulu zebhabhathane ezinobukhulu obuthathu ezineenkcazo ze-DN1400 kunye nezinto ze-Q235B zigqibile ukuhlolwa kwefektri ngokupheleleyo kwaye zilungele ukuhanjiswa kubathengi. Ezi valve ziphumelele uvavanyo oluqinileyo loxinzelelo lwe-hydrostatic kwaye akukho kuvuza kuyo yonke indawo, kwaye ii-actuators zombane zisebenza kakuhle emva kokuqaliswa. Okwangoku, zenza ukugqitywa okuneenkcukacha ukuqinisekisa ukuba zisetyenziswa zikwimeko esemgangathweni ophezulu.

Le valve yebhabhathane yombane eneendlela ezintathu sisixhobo sokulawula esiphambili esenzelwe ngokukodwa iinkqubo zokuhambisa ulwelo olukhulu. Umzimba oyintloko wenziwe ngentsimbi yekhabhoni ye-Q235B, enobuchule obugqwesileyo bokwakha, ukumelana nempembelelo kunye nomthamo wokuthwala uxinzelelo. Ifanelekile kwiimeko zokusebenza ze-DN1400 ezinkulu, ukuhlangabezana neemfuno zokuhambisa umbane omkhulu kwiimeko ezifana nokunikezelwa kwamanzi kunye nokutsalwa kwamanzi, iinethiwekhi zemibhobho kamasipala, kunye namanzi ajikelezayo kwimizi-mveliso. Ivalvu isebenzisa isakhiwo sokuvala esineenxalenye ezintathu, kwaye umphezulu wokuvala wenziwe ngezinto ezingagugiyo nezimelana nokugqwala, ezingagcini nje ngokunciphisa ukugqwala ngexesha lokuvula nokuvala, kodwa zikwafezekisa ukusebenza kokuvala okuzinzileyo okungenakuvuza ixesha elide, zigcina ukuvalwa okuthembekileyo naphantsi koxinzelelo oluphezulu kunye neemeko zoxinzelelo olukhulu. Ixhotyiswe ngee-actuators zombane ezisebenzayo, ixhasa zombini iindlela zokusebenza ngesandla ezikude kunye neendlela zokusebenza ngesandla, ivumela ukuphambuka okuchanekileyo, ukudibana kunye nokutshintsha indlela yokuhamba kwemibhobho eneendlela ezintathu, iphucula kakhulu ukusebenza kwenkqubo kwaye inciphisa iindleko zokusebenza ngesandla kunye nokugcinwa.

Kwinqanaba lokuhlolwa kwefektri, iqela lobuchwephesha lilandela ngokungqongqo imigangatho yoshishino ukwenza uvavanyo lokutywina nge-hydrostatic kwiivalvu, kungekho kuvuza okanye ukuguqulwa kuyo yonke indawo, kwaye ukusebenza kokutywina kuhambelana nomgangatho wokuvuza okungenalo. Kwangaxeshanye, kwenziwa imijikelo emininzi yokuvula nokuvala kwi-actuators zombane ukuqinisekisa ngokupheleleyo ukuchaneka kwazo kokubetheka, isantya sokuphendula, ukhuseleko olulinganiselweyo kunye nemisebenzi yokukhusela ukugqithiswa, ukuqinisekisa ukusebenza okuzinzileyo phantsi kweemeko zokusebenza ezinzima. Kwinqanaba lokugqiba inkangeleko, abasebenzi benza uhlolo olupheleleyo, ukugaya kunye nokupenda kwakhona kwiinkcukacha ezifana nokufakwa komzimba wevalvu, umphezulu wokutywina weflange, kunye neebhloko zesiphelo se-actuator, ukuqinisekisa ukuba zombini inkangeleko kunye nokusebenza kwemveliso kuyahlangabezana nemigangatho, kwaye kuyanelisa iimfuno ezingqongqo zabathengi zezixhobo zoshishino ezikumgangatho ophezulu.

Ngenxa yeenzuzo eziphambili ezifana nokuhamba kombane okunobubanzi obukhulu, ukutshintsha okuguquguqukayo kunye nolawulo oluzenzekelayo, iivalvu zebhabhathane zombane ezineendlela ezintathu zisetyenziswa kakhulu ekunikezelweni kwamanzi kunye nokutsalwa kwamanzi kamasipala, unyango lwelindle, amanzi ajikelezayo kwisikhululo samandla, ukuhanjiswa kolwelo lwamakhemikhali, isinyithi kunye nokwembiwa kwemigodi kunye neminye imimandla. Ivalvu enye inokuthatha indawo yeevalvu zebhabhathane ezininzi zemveli, yenza kube lula kakhulu uyilo lwepayipi, inciphise ukusetyenziswa kwamandla kwenkqubo kunye neendleko zokugcinwa kamva, okwenza kube lukhetho olufanelekileyo lokuphucula ngokukrelekrele nangokusebenzayo iinkqubo ezinkulu zolwelo.

(umfanekiso: DN1400 umbane oneendlela ezintathu zebhabhathane i-expansion joint)

Njengomvelisi weevalvu onamava angama-20 eminyaka, iJinbin Valves izibophelele ekuboneleleni abathengi ngeemveliso zeevalvu ezinokuthenjwa kunye nezisombululo ezenziwe ngokwezifiso. Ukuze ufumane ulwazi oluthe kratya malunga neevalvu zeebhabhathane zombane ezinkulu, okanye iimfuno zemeko yokusebenza ezenziwe ngokwezifiso, nceda uzive ukhululekile ukubonisana neqela lethu lobuchwephesha elingezantsi.
