Xa ukhetha isisombululo sokulawula ukuhamba kwamanzi esithembekileyo nesisebenzayo kwizicelo zemizi-mveliso okanye zikamasipala,iivalvu zesango ezihleli ngerabhazikhetho oludumileyo. Ezi valves zikwabizwa ngokuba zii-NRS (Recessed Stem) Gate Valves okanye ii-F4/F5 Gate Valves, zenzelwe ukulawula ukuhamba kolwelo kwiindawo ezahlukeneyo. Kweli nqaku, siza kuhlola iingenelo kunye neempawu zeevalve zesango ezihleli ngerabha kunye nesizathu sokuba ziyinxalenye ebalulekileyo yayo nayiphi na inkqubo yolawulo lolwelo.
Iivalvu zesango lerabha zisetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yokusebenza kwazo okuphezulu kokutywina kunye nesakhiwo sazo esihlala ixesha elide. Isihlalo serabha ngaphakathi kwivalvu sinika isitywino esiqinileyo kwisango, sinceda ukuthintela ukuvuza nokuqinisekisa indlela yokuvala ethembekileyo. Oku kwenza iivalvu zesango ezihleli ngerabha zilungele ukusetyenziswa apho isitywino esiqinileyo sibaluleke kakhulu, njengezityalo zonyango lwamanzi, iinkqubo zamanzi amdaka kunye nezixhobo zokucubungula iikhemikhali. Ukongeza, uyilo olufihliweyo lwe-valvu yesango le-NRS kulula ukuyisebenzisa nokuyigcina, nto leyo eyenza ukuba ibe sisisombululo esingabizi kakhulu kuyo nayiphi na inkqubo yolawulo lolwelo.
Enye yezona nzuzo ziphambili zeevalvu zesango ezihleli ngerabha kukukwazi kwazo ukuphatha iintlobo ngeentlobo zolwelo kunye neemeko zokusebenza. Nokuba ngamanzi, amanzi amdaka, udaka okanye iikhemikhali ezirhabaxa, iivalvu zesango ezihleli ngerabha zinokulawula ngokufanelekileyo ukuhamba kwezi zinto ngaphandle kokuphazamisa ukusebenza okanye ukuthembeka. Oku kuguquguquka kwenza iivalvu zesango ezihleli ngerabha zibe lukhetho lokuqala kwiinjineli kunye nabaqhubi abafuna isisombululo sokulawula ukuhamba okuthembekileyo nokuguquguqukayo ukuhlangabezana neemfuno zabo ezithile.
Ukongeza ekusebenzeni kwazo okugqwesileyo kokutywina kunye nokuguquguquka, iivalvu zesango ezihlala ngerabha zaziwa ngobomi bazo obude benkonzo kunye neemfuno ezincinci zolondolozo. Izihlalo kunye neengcango zeevalvu zerabha zenzelwe ukumelana nobunzima bokusetyenziswa okuqhubekayo kunye nokuchatshazelwa ziikhemikhali ezinobungozi, nto leyo ezenza zibe lukhetho oluqinileyo noluhlala ixesha elide lokusetyenziswa kolawulo lolwelo. Ngokufakelwa ngokufanelekileyo kunye nokugcinwa rhoqo, iivalvu zesango ezihlala ngerabha zinokubonelela ngeminyaka yokusebenza ngaphandle kweengxaki, ukunciphisa ixesha lokungasebenzi kunye neendleko zokugcinwa kwezakhiwo zoshishino kunye nomasipala.
Ngamafutshane, iivalvu zesango ezihleli ngerabha, ezaziwa ngokuba ziivalvu zesango ze-NRS okanye iivalvu zesango ze-F4/F5, ziyinxalenye ebalulekileyo yayo nayiphi na inkqubo yolawulo lolwelo ngenxa yokusebenza kwazo okugqwesileyo kokutywina, ukuguquguquka, kunye nobomi benkonzo ende. Xa zithengiswa ngokufanelekileyo, iivalvu zesango ezihleli ngerabha zinokutsala uluhlu olubanzi lwamashishini kunye nezicelo, zibonelela ngezisombululo zokulawula ukuhamba kwamanzi ezinokuthenjwa nezisebenzayo kwiintlobo ngeentlobo zolwelo kunye neemeko zokusebenza. Ngoyilo lwazo olungabizi kakhulu nolungadingi kulungiswa kakhulu, iivalvu zesango ezihleli ngerabha zilukhetho oluhle kakhulu kwizakhiwo zoshishino kunye nomasipala ezifuna isisombululo sokulawula ukuhamba kwamanzi esinokuthenjwa nesiguquguqukayo.
Ngaphandle koko, iTWS Valve, eyaziwa ngokuba yiTianjin Tanggu Water Seal Valve Co., Ltd, yivalvu yesihlalo eyomeleleyo exhasa amashishini aphambili kwezobuchwepheshe, iimveliso zezi: ivalvu yebhabhathane yesihlalo esithambileyo, ivalvu yebhabhathane yelug,ivalvu yebhabhathane ejikelezayo ephindwe kabini, ivalvu yebhabhathane engaqhelekanga ephindwe kabini,ivalvu yokulinganisela, ivalvu yokujonga iipleyiti ezimbini ze-wafer, i-Y-Strainer njalo njalo. Ukuba unomdla kwezi valve, nceda unxibelelane nathi. Enkosi kakhulu!
