I-NSEN Metal to metal seal I-valve ye-butterfly ephindwe kabili ehambisana ne-Triple offset isebenzisa isakhiwo se-“Metal To Metal Seat ring”, okungukuthi indandatho yokuvala idiski/isihlalo ye-valve yonke iyinsimbi enokuphathwa okuqinile. Isakhiwo sokuvala insimbi esiqinile singasusa inkinga yokuvuza nokusebenza kokuvala okungazinzile okubangelwa isihlalo sohlobo lwe-U noma isihlalo sohlobo lwe-L. Ngaphandle kwalokho, umklamo wethu wokuvala ngokukhethekile ungavumela i-valve ukuthi isebenze ngokucindezela okuhlukile ngaphandle kokunciphisa ingcindezi yepayipi.

• I-geometry ye-offset kathathu

• Ukuvalwa kwendandatho yesivalo sensimbi ehlanganisiwe

• Akukho ukuvuza kuzo zombili izindlela

• Umphini ovimbela ukuqhunyiswa

• Umklamo wokuvikela umlilo ku-API607

• Ukuvalwa Kwesihlalo Nediski Okungashintshwa

• Ukulawula okungu-0°-90°, akukho ndawo yokugxuma

• Akukho ukungqubuzana

Umklamo wokuvala oqondene nezinhlangothi ezimbili

Lolu chungechunge lungafinyelela isidingo sokungavuki nhlobo kuzo zombili izindlela ezijwayelekile ezihlobene. Ukuvalwa kwe-bi-directional kwenza ukufakwa kube nokugeleza kunoma yiluphi uhlangothi, ngokuqondile, noma ngokuvundlile futhi ngaphandle kokuvuza. Ukucindezela okuphezulu kakhulu okungafinyelela ku-600LB.

Umklamo ongenazingxabano

Ukusetshenziswa kwesakhiwo se-eccentric esiphindwe kathathu kunciphisa ukungqubuzana ngesikhathi sokushintshana phakathi kobuso bokuvala bediski nomzimba we-valve, ukuze idiski ikwazi ukukhulula ngokushesha isihlalo se-valve lapho i-valve ye-butterfly eccentric kathathu ivulwa noma ivaliwe.

Isakhiwo sokuphepha esiphindwe kabili
Ukuze kuvinjelwe izimo zokuguquguquka kwediski, ukungalungi kahle kwesiqu, ukuvala ubuso bulumana ngenxa yokucindezela koketshezi kanye nokushisa, i-NSEN butterfly valve isebenzisa izindandatho ezimbili ezihlukene zokudonsa ohlangothini olungaphezulu noluphansi lwediski okuqinisekisa ukuthi i-valve isebenza ngaphansi kwanoma yiziphi izimo.

Ukuze kugwenywe ingozi engaba khona ebangelwa ukuqhumisa isiqu, isakhiwo sesiqu esilwa nokuqhumisa senzelwe i-valve ye-butterfly ye-NSEN.

Akukho Umklamo Wendawo Efile     
Ukusetshenziswa esimweni sokulawula/sokulawula kuye kwacatshangelwa ngesikhathi sokuklama. Kusetshenziswa isisekelo sokuvala se-valve ye-butterfly eccentric kathathu, ama-valve e-NSEN aqaphela "Akukho ukwakheka kwendawo efile" okungagcini nje ngokugwema izinkinga "zendawo yokuvula" yama-valve e-butterfly avamile kodwa futhi kuqeda inkinga ye-valve yokuthi ayikwazanga ukulawulwa noma ukulawulwa uma ise-engeli yayo encane yokuvula engabangelwa ukungqubuzana noma ezinye izinto ezingaphephile. Lokhu kusho ukuthi i-butterfly ye-NSEN ingalawula noma ilawule i-medium kusukela cishe kuma-degree angu-0 kuya kwangu-90.

Izinto zendandatho yesihlalo       
Indandatho yesihlalo se-NSEN metal sealed butterfly valve yenziwe ngensimbi eyenziwe nge-alloy enezinzuzo zokulwa nokukhuhla, ukumelana nokuguguleka, ukumelana nokucindezela okuphezulu kanye nokushisa kanye nokuphila isikhathi eside.

Indandatho yokuvala engashintshaniswayo      

Izindandatho zokuvala zediski nesihlalo zonke zihlukile ze-NSEN series butterfly valve, futhi zingashintshwa uma kudingeka. Indandatho yokuhlala yediski noma isihlalo ingashintshwa ngayinye uma iphukile okungehlisi nje izindleko zakho zokulungisa kodwa futhi kwenza ukulungiswa kube lula.

Isakhiwo Esiqinile Ngokulinganayo      

Indandatho yokuvala yevalvu yebhabhathane iqiniswe ngamabholidi/amantongomane asakazwe ngokulinganayo. Ibholidi ngalinye lisendaweni efanele futhi libekezelela amandla ngokulinganayo. Lesi sakhiwo siqeda izinkinga zokuvuza noma indandatho yokuvala ekhululekile ngenxa yamandla angalingani amabholidi namantongomane.

Umklamo kanye nesakhiwo esiphephile emlilweni      

Isakhiwo esihlala ngensimbi senza i-valve ivikeleke emlilweni futhi ihlangabezane nesidingo ku-API607.

I-torque ihleli phansi

Amavalvu angavalwa ngezindlela ezimbili ngaso sonke isikhathi. Ukuvala kufezwa nge-torque enikezwa yi-actuator kodwa hhayi ngamandla aphakathi okuqinisekisa ukusebenza kahle kokuvala ngaphansi kwengcindezi yokusebenza ephezulu nephansi. Futhi amavalvu angaphumelela ukuhlolwa kwe-API609 kanye ne-ISO5208.

Uhlelo lokupakisha olulayishiwe bukhoma
Ngokuvamile, abantu bagxila kuphela ekuvuzeni kwangaphakathi okwenzeka engxenyeni yesihlalo kodwa bangayinaki inkinga yokuvuza kwangaphandle, okungukuthi ukuvuza kwengxenye yokupakisha. Umklamo wokupakisha ogcwele bukhoma onesakhiwo esihlanganisiwe uqinisekisa ukuthi i-NSEN Butterfly valve ingafinyelela ukuvuza okuphezulu okungu-≤20ppm. Kwenza ukuvala ukupakisha kube okuthembekile futhi kwandisa isikhathi sokupakisha esingenakulungiswa.

Ibhokisi lamagiya

Ibhokisi lamagiya elisetshenziswa ngesandla elitholakala ngekhwalithi ephezulu kanye nesakhiwo sokuphepha, elihlanganiswe nezici zamanje zebhokisi lamagiya lomkhiqizo owaziwayo kanye nezinga lokuvikela elifinyelela ku-IP 67.

I-NSEN ilandela ngokuqinile ukulungiswa kwamahhala, ukushintshwa kwamahhala kanye nezinsizakalo zokubuyiselwa kwamahhala zingakapheli izinyanga eziyi-18 ngemuva kokuthi ivalvu isisebenzile noma izinyanga eziyi-12 ngemuva kokufakwa nokusetshenziswa epayipini ngemuva kokusebenza kwangaphambilini (okuzofika kuqala). 

Uma kwenzeka ivalvu yehluleka ngenxa yenkinga yekhwalithi ngesikhathi sokusetshenziswa epayipini ngaphakathi kwesikhathi sewaranti yekhwalithi, i-NSEN izohlinzeka ngensizakalo yewaranti yekhwalithi yamahhala. Insizakalo ngeke iphele kuze kube yilapho ukwehluleka sekulungisiwe futhi ivalvu ivame ukusebenza futhi iklayenti lisayina incwadi yokuqinisekisa.

Ngemva kokuphela kwesikhathi esishiwo, i-NSEN iqinisekisa ukuhlinzeka abasebenzisi ngezinsizakalo zobuchwepheshe ezisezingeni eliphezulu ngesikhathi noma nini lapho umkhiqizo udinga ukulungiswa nokunakekelwa.
