I-NSEN Metal to metal seal I-valve yebhabhathane ephindwe kabini ephuma ecaleni isebenzisa ulwakhiwo lwe-"Metal To Metal Seat ring", oko kukuthi, i-valve sealing ring yediski/isihlalo zonke ziyintsimbi enonyango oluqinileyo. Ulwakhiwo lwentsimbi eqinileyo lunokuphelisa ingxaki yokuvuza kunye nokusebenza okungazinziyo kokutywina okubangelwa sisihlalo sohlobo lwe-U okanye isihlalo sohlobo lwe-L. Ngaphandle koko, uyilo lwethu lokutywina ngokukodwa lunokuvumela ivalve ukuba isebenze kuxinzelelo olwahlukileyo ngaphandle kokunciphisa uxinzelelo lombhobho.

Uyilo lokutywina oluhamba ngamacala amabini

Olu luhlu lunokufikelela kwimfuneko yokungavuzi nto kuzo zombini iindlela kumgangatho ohambelanayo. Ukuvalwa kwe-bi-directional kwenza ukufakwa kube nokuhamba kwicala ngalinye, ngokuthe nkqo, okanye ngokuthe tye kwaye ngaphandle kokuvuza. Uxinzelelo oluphezulu olunokufikelela kwi-600LB.

Uyilo olungenangxabano

Ukusetyenziswa kwesakhiwo se-triple eccentric kunciphisa ukungqubana ngexesha lokutshintsha phakathi komphezulu wokutywina wediski kunye nomzimba wevalvu, ukuze idiski ikwazi ukukhupha ngokukhawuleza isihlalo sevalvu xa ivalvu yebhabhathane ye-triple eccentric ivuliwe okanye ivaliwe.

Ulwakhiwo lokhuseleko oluphindwe kabini
Ukuze kuthintelwe iziganeko zokuguquka kweediski, ukungalungelelani kwesiqu, ukutywina ukulumana kobuso okubangelwa luxinzelelo lolwelo kunye nobushushu, ivalvu yebhabhathane yeNSEN isebenzisa iiringi ezimbini ezahlukeneyo zokutyhala kwicala eliphezulu nelisezantsi lediski eziqinisekisa ukuba ivalvu isebenza phantsi kwayo nayiphi na imeko.

Ukuze kuthintelwe ingozi enokubakho ngenxa yokuphuma kwesiqu, isakhiwo sesiqu esichasene nokuphuma kwesiqu senzelwe ivalvu yebhabhathane ye-NSEN.

Akukho Uyilo lweNdawo eFileyo     
Ukusetyenziswa kwimeko yokulawula/yokulawula kuye kwathathelwa ingqalelo ngexesha loyilo. Ngokusebenzisa isiseko sokutywina sevalvu yebhabhathane engaqhelekanga kathathu, iivalvu ze-NSEN zenza "Akukho lwakhiwo lwendawo efileyo" olungagcini nje ngokuthintela iingxaki "zendawo yokutsiba yokuvula" yeevalvu zebhabhathane eziqhelekileyo kodwa lukwasusa ingxaki yevalvu yokuba ayinakulawulwa okanye ayilawulwa xa ikwi-engile yayo encinci yokuvula enokubangelwa kukungqubana okanye ezinye izinto ezingakhuselekanga. Oku kuthetha ukuba ibhabhathane le-NSEN linokulawula okanye lilawule i-medium ukusuka kwi-0 degrees ukuya kwi-90 degrees.

Izinto zendandatho yesihlalo       
Iseti yesihlalo se-NSEN metal sealed butterfly valve yenziwe ngentsimbi ye-alloy eyenziwe ngobuchule enezibonelelo zokulwa nokukhuhla, ukumelana nokuguguleka, uxinzelelo oluphezulu kunye nokumelana nobushushu kunye nobomi obude.

Indandatho yokutywina enokutshintshwa      

Iiringi zokuvala zediski kunye nesihlalo zonke zahlukile kwi-NSEN series butterfly valve, kwaye zinokutshintshwa xa kufuneka. Iringi yokuhlala yediski okanye isihlalo ingatshintshwa nganye nganye xa yaphukile, nto leyo engagcini nje ngokunciphisa iindleko zakho zokulungisa kodwa ikwanceda ukulungiswa kube lula.

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.

Uyilo kunye nesakhiwo esikhuselekileyo emlilweni      

Ulwakhiwo lwentsimbi oluhlala phantsi lwenza ivalvu ikhuseleke emlilweni kwaye ihlangabezana neemfuno ze-API607.

I-torque ehleli phantsi

Iivalvu zingasoloko zitywinwa kwicala elinye. Ukutywinwa kwenziwa nge-torque enikezelwa yi-actuator kodwa kungekhona ngamandla aphakathi aqinisekisa ukusebenza okuthembekileyo kokutywinwa phantsi koxinzelelo oluphezulu noluphantsi lokusebenza. Kwaye iivalvu zinokuphumelela uvavanyo lwe-API609 kunye ne-ISO5208.

Inkqubo yokupakisha elayishiweyo ephilayo
Ngokubanzi, abantu bagxila kuphela ekuvuzeni kwangaphakathi okwenzeka kwindawo yesihlalo kodwa abayinaki ingxaki yokuvuza kwangaphandle, oko kukuthi ukuvuza kwendawo yokupakisha. Uyilo lokupakisha olugcweleyo olunesakhiwo esidibeneyo luqinisekisa ukuba ivalvu ye-NSEN Butterfly inokufikelela ekuvuzeni okuphezulu ≤20ppm. Yenza ukutywinwa kokupakisha kuthembeke kwaye kwandisa ixesha lokupakisha elingenakugcinwa.

Ibhokisi yegiya

Ibhokisi yegiya yesandla enikezelwa ngomgangatho ophezulu kunye nolwakhiwo lokhuseleko, oludibene neempawu zebhokisi yegiya yophawu lwangoku eyaziwayo kunye nenqanaba lokhuseleko lifikelela kwi-IP 67.

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.
