I-Segment Ball Valve, I-Segment Wafer Ball Valve, V uhlobo lwe-Ball Valve

Isingeniso

Lolu hlobo lwe-valve yebhola ingeye-valve yebhola engaguquki futhi iyisivalo sebhola esisodwa esivala isihlalo.Ukusebenza kokulungiswa kuhamba phambili ku-valve yebhola, isici sokugeleza siyiphesenti elilinganayo, futhi isilinganiso esilungisekayo sifika ku-100:1.I-slit yayo emise okuka-V inesenzo sokugunda nesihlalo sensimbi, ilungele imidiya equkethe imicu, izinhlayiya ezincane eziqinile, udaka.

I-valve yebhola inokuzungezisa okufanayo okungu-90 degree, ngaphandle kokuthi indikimba yepulaki iyindilinga enendilinga embobeni noma iphaseji ku-eksisi yayo.I-valve yebhola isetshenziswa kakhulu epayipini ukusika, ukusabalalisa kanye nokushintsha isiqondiso sokugeleza kwe-medium.Idinga kuphela ukujikeleziswa ngamadigri angama-90 futhi i-torque ingavalwa ngokuqinile.Ama-valve ebhola afaneleka kangcono ukusetshenziswa njengama-valve okushintshayo nawokuvala, kodwa intuthuko yakamuva iklame ama-valve ebhola ukuze anikeze ukugobhoza nokulawula ukugeleza, njengama- V-ball valves.

Izici

Ifanele ukusebenza okuvamile, ukuvulwa nokuvala ngokushesha, isisindo esincane, ukumelana noketshezi oluncane, isakhiwo esilula, ivolumu encane ehlobene, isisindo esilula, ukugcinwa okulula, ukusebenza kahle kokuvala, okungavinjelwe isiqondiso sokufaka, isiqondiso sokugeleza kwendawo ephakathi kungase kube ngokunganaki. , akukho ukudlidliza, umsindo ophansi.

1. Isakhiwo se-monolithic somzimba we-valve: Umzimba we-valve wohlobo lwe-clamp kanye ne-valve yohlobo lwe-flange yohlobo lwe-V yonke iyisakhiwo esinamathele ohlangothini, esinokuqina okuqinile kwesakhiwo futhi akulula ukubangela ukuwohloka nokuvuza.

2. Ama-bearings azigcobayo aphezulu naphansi: Umzimba we-valve ufakwe ama-bearings angaphezulu naphansi okuzigcoba, anendawo enkulu yokuxhumana ne-valve stem, umthamo wokuthwala okuphezulu kanye ne-coefficient encane yokungqubuzana, okunciphisa i-torque ye-valve.

I-3, isihlalo se-valve singakhethwa ngokuya ngezidingo zezimo ezimaphakathi nezisebenzayo, uphawu lwensimbi oluqinile noma uphawu oluthambile lwe-PTFE: isihlalo sensimbi esiqinile se-seal seal surface sibhekene ne-alloy eqinile, i-spherical hard chrome noma i-spray welding, i-ion nitriding nokunye ukwelashwa okunzima. , Impilo yesevisi yendawo yokuvala iyathuthukiswa futhi ukumelana nezinga lokushisa kuyathuthukiswa;isihlalo sevalvu ye-PTFE evalayo esithambile noma isihlalo sevalve ye-PTFE esiqinisiwe sisebenza kahle ngokuvala nokugqwala, futhi sinokuvumelana nezimo okubanzi.

4. Umnotho nokusebenziseka: Umzimba we-valve unesisindo esilula, i-torque ye-valve stem incane, futhi ukucaciswa okuhambisanayo kwama-actuator womoya noma kagesi kuncane, okungabizi kakhulu uma kuqhathaniswa nezinye izinhlobo zama-valve alawulayo.

5, okuphakathi kuvumelana nobubanzi obubanzi: ngenxa yamandla okugunda phakathi kokuvula okumise okwe-V kanye nesihlalo se-valve, kanye nendlela yokugeleza ebushelelezi neyindilinga ye-valve cavity, okuphakathi akulula ukunqwabelana emgodini ongaphakathi, ngakho ilungele uketshezi oluphakathi, Ifanele ukulawulwa kwesistimu nge-fiber kanye nemidiya yezinhlayiyana eziqinile.

Dizayina futhi wenze amazinga

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

2. Isilinganiso sokushisa kwengcindezi: ASME 816.34-2003, IS0 7005-1

3. Izinga lobude besakhiwo: Uhlobo lwesiqeshana: uhlobo lweFlange olujwayelekile lwebhizinisi: ISAS75.04-1995, IEC/DIN534-3-2

4, ukuzivumelanisa nezinga lokushisa uhla: -29 °C -1 ~ 500C lokushisa evamile uhlobo 2goC_2500C medium lokushisa uhlobo 2goC_3500C izinga lokushisa eliphezulu hlobo

5, ukubeka uphawu kanye namazinga okuhlola amandla

Amandla nokuvala izinga lokuhlola: GB/T 4213-2007

Ileveli yophawu oluqinile: Uma umsebenzisi engenazo izidingo ezikhethekile, kusetshenziswa izinga elilandelayo lethebula.Uma umsebenzisi eyicela, ingenziwa ngokuya ngezinga lezinga le-GB/T 4213-2007?V.Ukucindezela kokuhlolwa kwamandla izikhathi ezingu-1.5 zokucindezela okuzisholo.Ukuhlolwa kwe-seal ekupakisheni nase-flange kwenziwa ngengcindezi ye-1.1 izikhathi zokucindezela okujwayelekile.Isigxivizo sesihlalo sivivinywa ngokuya ngomehluko omkhulu wengcindezi.Uma umehluko omkhulu wengcindezi ungacacile, cindezela ukuhlolwa kwe-1.0MPa (umfutho wamanzi), lapho umehluko omkhulu wengcindezi ungaphansi kuka-0.6MPa, ukuhlolwa kwenziwa ngengcindezi engu-0.6MPa, kanti okuphakathi kuhlolwe ngamanzi anokugqwala. kanye ne-scale inhibitor.
