Isishwankathelo

I-NSEN Lug Triple offset butterfly valve isetyenziswa kakhulu kwi-pulp, iphepha, amashishini eekhemikhali, i-petrochemical kunye ne-refinery. I-butterfly valve ene-tightness ephezulu isebenza kuzo zombini iinkqubo zolawulo kunye nezokuvala.

• Ukuvalwa okune-laminated kunye nokuvalwa kwesinyithi ukuya kwisinyithi

• Icala elihamba ngababini kunye necala elihamba ngababini

• I-torque ephantsi yokuvula

• Akukho kungqubana phakathi kwesihlalo kunye nokutywinwa

• Ubuso obugobileyo bokuvala ikhowuni

• Ibheri ethambisiweyo

I-NSEN inika ukhetho lwesihlalo esizinzileyo kunye nesihlalo esidadayo esinokulungiswa ngaphandle kokususa ivalvu kwindawo yayo, inganciphisa ixesha lokulungisa kwaye iphucule kakhulu ukusebenza kakuhle. Isihlalo esizinzileyo sisebenza kwivalvu apho ukuhamba okuphakathi kuya phambili, ngoko ke ukutywinwa okuqinileyo kwenzelwe icala elinye, kwaye kufuneka kuthathelwe ingqalelo kwicala lokuhamba xa kwakufakwa. Nangona isihlalo sizinzile, kodwa ukutywinwa kwediski kusenokususwa. Ukuba ivalvu isebenza nesihlalo esidadayo, ungayifaka nakweliphi na icala.

I-torque evulekileyo ephantsi

Olu luhlu lusebenzisa iRadial Dynamically Balanced Sealing System, ngoyilo olucwangcisiweyo, amandla asetyenziswa kumacala omabini okungena kunye nokuphuma kwediski yebhabhathane ayalingana ukuze anciphise ngempumelelo i-torque yokuvula ivalvu.

Ukuzithambisa ngokwakhoibhereyitha

Ukuze kuncitshiswe i-torque yokusebenza kwaye kuthintelwe ukutshixeka kwesiqu phantsi kokuvulwa nokuvalwa rhoqo, kufakwe i-bushing yokuzithambisa eyenzelwe wena.

Ulwandlelizinto zeringi        
Indandatho yesitywino yohlobo lwe-laminated yenziwe ngepleyiti yentsimbi engagqwaliyo enegrafiti/ifayibha yekhabhoni/i-PTFE njl. Xa kuthelekiswa nezinto zepleyiti ye-asbestos zerabha, izinto zethu zokwamkela ziyanxitywa ngakumbi, azigugi, zithembekile kwaye zingcono kwindalo esingqongileyo.

Iseti yesihlalo eyenziwe ngevalvu yebhabhathane etywiniweyo yenziwe ngentsimbi ye-alloy eyenziwe ngobuchule enezibonelelo zokuchasana nokukhuhla, ukumelana nokuguguleka, uxinzelelo oluphezulu kunye nokumelana nobushushu kunye nobomi obude.

Pukuxhalaba-utywino oludibeneyoinkqubo
I-NSEN yamkela olu lwakhiwo ukuqinisekisa ukuba ukuvuza kwevalvu kunokufikelela kwi-≤20ppm ubuninzi. Ulwakhiwo lokutywina oluguquguqukayo luyafumaneka ukuba kuyimfuneko, nto leyo eyenza ukutywina kokupakisha kube kwimeko elungileyo kwaye kwandise ixesha lokugcinwa kwasimahla kokupakisha.

Ulwakhiwo Oluzinzileyo Ngokulinganayo      

Indandatho yokutywina yevalvu yebhabhathane iqiniswe ngeebholiti/amantongomane asasazwe ngokulinganayo. Ibholiti nganye ibekwe ngokuchanekileyo kwaye inamandla ngokulinganayo. Olu lwakhiwo lususa iingxaki zokuvuza okanye indandatho yokutywina ekhululekileyo ngenxa yamandla angalinganiyo eebholiti namantongomane.

I-NSEN ilandela ngokungqongqo iinkonzo zokulungisa zasimahla, ukutshintshwa kwasimahla kunye nokubuyiselwa kwasimahla kwiinyanga ezili-18 emva kokuba ivalvu ingasebenzi okanye iinyanga ezili-12 emva kokufakwa nokusetyenziswa kwipayipi emva kokusebenza kwangaphambili (ekuza kuqala). 

Kwimeko apho ivalvu iye yawa ngenxa yengxaki yomgangatho ngexesha lokusetyenziswa kwipayipi ngexesha lewaranti yomgangatho, i-NSEN iya kubonelela ngenkonzo yewaranti yomgangatho yasimahla. Inkonzo ayizukuphela de kube ukusilela kulungisiwe kwaye ivalvu iyasebenza kwaye umthengi utyikitye ileta yokuqinisekisa.

Emva kokuphela kwexesha elichaziweyo, i-NSEN iqinisekisa ukubonelela abasebenzisi ngeenkonzo zobugcisa ezisemgangathweni ngexesha nanini na xa imveliso ifuna ukulungiswa nokugcinwa.
