    Ulwakhiwo lweMveliso kunye neeNzuzo zokusebenza

    1. Ulwakhiwo lwe-Anti-Corrosion lwentsimbi engenasici

    Izinto eziphambili ezifana nomzimba wevalvu, ipleyiti yesango kunye nesigqubuthelo sevalvu zenziwe ngokudibeneyo ngentsimbi engagqwaliyo engama-304/316L. Le nto ye-316L iqulethe izinto ze-molybdenum, ezinokumelana nokugqwala okunamandla kakhulu kwi-ion ze-chloride, iityuwa ze-acid-base kunye nezinye izinto ezigqwala, okwenza ukuba zifaneleke kwiimeko ezinamandla zokugqwala ezifana nobunjineli beekhemikhali kunye nokususwa kwetyuwa emanzini olwandle. Umphezulu ucoliwe kakuhle ukunciphisa ukubekwa kwemidiya kunye nokumelana nokuhamba kwamanzi, ukwandisa ubomi benkonzo yesixhobo.

    2. Uyilo lweTywina elikhethekileyo elinobubanzi obukhulu

    Kwi-DN1600 enobubanzi obukhulu kakhulu, kusetyenziswa isakhiwo esizilungelelanisa nesango eliphindwe kabini. Ipleyiti yesango ihlawulela ukuguqulwa kobushushu kunye nokuphambuka kokufakwa komzimba wevalvu ngoyilo lwe-wedge, okwenza ukuba itywinwe kabini ingabi namanzi. Umphezulu wentsimbi eqinileyo uphathwa nge-Stellite alloy hardfacing, enobunzima obufikelela kwi-HRC45-50, enganyangekiyo kwaye imelana nobushushu obuphezulu, isombulula ngokupheleleyo indawo yentlungu yokusilela kwetywina kwiivalvu ezinkulu.

    3. Uthumelo olusebenzayo kunye nokusebenza okulula

    Ixhotyiswe ngenkqubo yokudlulisa umsonto we-trapezoidal yangaphandle enezikrufu, ubude obuveziweyo besiqu sevalvu bubonakalisa ngokuthe ngqo ukuvulwa kwevalvu, nto leyo eyenza kube lula ukujonga nokugcina indawo ikwimeko entle. Ukudibanisa indlela yokunciphisa ivili lesandla kunye negiya le-worm kunciphisa kakhulu i-torque yokusebenza, okuvumela umntu omnye ukuba avule aze avale ivalvu enkulu ye-DN1600. Ii-actuators zombane okanye ze-pneumatic zinokufakelwa ngokuzithandela ukuze zilungelelanise neenkqubo zolawulo oluzenzekelayo kwaye zikwazi ukulawula ngokuchanekileyo kude.

    4. Ukuthembeka Okuphezulu kunye noLondolozo Oluphantsi

    Uyilo lomjelo wokuhamba ngokuthe tye lune-coefficient yokumelana nokuhamba kwamanzi ≤0.1 xa luvuliwe ngokupheleleyo, nto leyo enciphisa ukulahleka kwamandla emidiya. Isakhiwo sesitywino esiphindwe kathathu (ukupakisha i-graphite eguquguqukayo + indandatho yentsimbi ebotshelelweyo + i-gland) sinciphisa ngempumelelo umngcipheko wokuvuza kwangaphandle kwesiqu sevalvu. Umzimba wevalvu usebenzisa uyilo oluqinisiweyo lodonga, olumelana noxinzelelo oluphezulu kunye nokuguquguquka, oluhlangabezana neemfuno zokuthwala uxinzelelo lwemibhobho emikhulu. Isakhiwo siphela kulula ukusiqhekeza nokusihlanganisa, kwaye ipleyiti yesango kunye nesiqu sevalvu zinokukhutshwa zizonke ngaphandle kokuqhekeza umbhobho, nto leyo enciphisa iindleko zokugcinwa kamva.
