ICandelo leValve yeBhola, i-Segment Wafer Ball Valve, uhlobo lwe-V yeBhola

Intshayelelo

Olu hlobo lwevalve yebhola yeyevalve yebhola esisigxina kwaye ikwasisitulo esinye sokutywina sebhola.Ukusebenza kokulungelelaniswa kweyona nto ibhetele kwi-valve yebhola, uphawu lokuhamba luyipesenti elinganayo, kwaye umlinganiselo ohlengahlengiswayo ufikelela kwi-100: 1.I-V-shaped slit yayo inesenzo sokucheba kunye nesihlalo sesinyithi, esifanelekileyo kwimidiya equlethe iifayibha, amasuntswana amancinci aqinileyo, i-slurry.

Ivalve yebhola inomjikelezo ofanayo we-90 degree, ngaphandle kokuba umzimba weplagi yingqukuva enesetyhula emngxunyeni okanye kwi-axis yayo.Ivalve yebhola isetyenziswa ikakhulu kumbhobho ukusika, ukusasaza kunye nokutshintsha indlela yokuhamba kwe medium.Ifuna kuphela ukujikelezwa kwe-90 degrees kwaye i-torque ingavalwa ngokuqinileyo.Iivalve zebhola zezona zilungele ukusetyenziswa njengokutshintsha kunye nokuvala iivalvu, kodwa uphuhliso lwakutsha nje luyile iivalvu zebhola ukunika i-throttling kunye nokulawula ukuhamba, okufana ne-V-ball valves.

Iimpawu

Ifanelekile ukusebenza rhoqo, ukuvulwa ngokukhawuleza kunye nokuvala, ubunzima obulula, ukuxhathisa ulwelo oluncinci, ulwakhiwo olulula, umthamo omncinci ohambelanayo, ubunzima obulula, ukugcinwa okulula, ukusebenza kakuhle kokutywinwa, okungathintelwanga ngumkhombandlela wofakelo, ukuhamba kwecala eliphakathi kunokuba ngqongqo. , akukho ngcangcazelo, ingxolo ephantsi .

1. Ubume be-monolithic ye-valve yomzimba: Umzimba wevalve wohlobo lwe-clamp kunye nohlobo lwe-flange ye-V-uhlobo lwebhola ye-valve yonke i-integrated side-mounted structure, enobume obuqinileyo kwaye akulula ukwenza i-deformation kunye nokuvuza.

2. Iibheringi ezizithambisayo eziphezulu nezisezantsi: Umzimba wevalve uxhotyiswe ngeebheringi ezizithambisayo eziphezulu nezisezantsi, ezinendawo enkulu yokunxibelelana nesiqu sevalve, amandla aphezulu okuthwala kunye ne-coefficient encinci ye-friction, enciphisa i-torque yevalve.

I-3, isihlalo sevalve sinokukhethwa ngokweemfuno zomgangatho ophakathi kunye neemeko zokusebenza, itywina eliqinileyo okanye i-PTFE itywina elithambileyo: isihlalo sentsimbi esiqinileyo sokutywina indawo engaphezulu kwe-alloy enzima, i-chrome engqukuva okanye i-spray welding, i-ion nitriding kunye nolunye unyango olunzima. , Ubomi benkonzo yendawo yokutywina buphuculwe kwaye ukuchasana nokushisa kuphuculwe;isihlalo sevalve yePTFE etywiniweyo okanye isitulo sevalve yePTFE eyomeleziweyo sinokutywinwa okusebenzayo kunye nokumelana nomhlwa, kwaye sinokuguquguquka okubanzi.

4. Uqoqosho kunye nokusebenza: Umzimba we-valve unobunzima obunzima, i-valve stem torque encinci, kunye neenkcukacha ezihambelanayo ze-pneumatic okanye i-actuator zombane zincinci, ezingabizi kakhulu xa kuthelekiswa nezinye iindidi ze-valve ezilawulayo.

I-5, i-medium ilungelelanisa kuluhlu olubanzi: ngenxa yamandla okucheba phakathi kokuvula okumilise okwe-V kunye nesihlalo sevalve, kunye nendlela egudileyo kunye nengqukuva ejikelezayo yomgodi wevalvu, okuphakathi akukho lula ukuqokelela kumgodi ongaphakathi, ngoko ilungele ulwelo oluphakathi, Lufanelekile kulawulo lwenkqubo ngefiber kunye nemithombo yeendaba eqinileyo.

Imigangatho yoyilo kunye nokuveliswa

1. Umgangatho weFlange: ASME B 16.5, EN 1092-1: 2001, GB/T 9113.1-2010, JB/T 79.1-1994, HG/T20592-2009

2. Iqondo loxinzelelo lobushushu: ASME 816.34-2003, IS0 7005-1

3. Umgangatho wobude besakhiwo: Uhlobo lwekliphu: umgangatho weshishini Uhlobo lweFlange: ISAS75.04-1995, IEC/DIN534-3-2

4, ukuziqhelanisa kuluhlu lobushushu: -29 °C -1 ~ 500C uhlobo lobushushu eqhelekileyo 2goC_2500C uhlobo lobushushu eliphakathi 2goC_3500C uhlobo lobushushu eliphezulu

I-5, ukutywinwa kunye nemigangatho yokuvavanya amandla

Umgangatho wokuvavanya amandla kunye nokutywinwa: I-GB / T 4213-2007

Inqanaba lotywino olunzima: Xa umsebenzisi engenazo iimfuno ezikhethekileyo, umgangatho wetafile ulandelayo uyasetyenziswa.Xa umsebenzisi eyicela, inokuphunyezwa ngokomgangatho we-GB/T 4213-2007?V.Uxinzelelo lovavanyo lwamandla ngamaxesha angama-1.5 oxinzelelo lwegama.Uvavanyo lwesitywina ekupakisheni kunye ne-flange luqhutyelwa ngoxinzelelo lwe-1.1 amaxesha oxinzelelo oluncinci.Isitywina sesihlalo sivavanywa ngokomahluko omkhulu woxinzelelo.Xa umahluko omkhulu woxinzelelo ungacacanga, cinezela uvavanyo lwe-1.0MPa (uxinzelelo lwamanzi), xa umahluko omkhulu wengcinezelo ungaphantsi kwe-0.6MPa, uvavanyo lwenziwa ngoxinzelelo lwe-0.6MPa, kwaye i-medium ivavanywa ngamanzi nge-corrosion. kunye ne-scale inhibitor.
