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 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 okwe-V inesenzo sokugunda nesihlalo sensimbi, ilungele imidiya equkethe imicu, izinhlayiya ezincane eziqinile, udaka.

I-valve yebhola inokuzungezisa okufanayo okungu-90 degree, ngaphandle kokuthi umzimba wepulaki uyindilinga enendilinga embobeni noma indlela edlula 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 okushintsha nokuvala, kodwa intuthuko yakamuva iklame ama-valve ebhola ukuze anikeze ukugeleza nokugeleza kokulawula, njengama-valve ebhola le-V.

Izici

Ifanele ukusebenza okuvamile, ukuvulwa nokuvala okusheshayo, isisindo esincane, ukumelana noketshezi oluncane, isakhiwo esilula, ivolumu encane ehlobene, isisindo esincane, ukugcinwa okulula, ukusebenza kahle kokuvala, okungavinjelwe isiqondiso sokufaka, isiqondiso sokugeleza se-medium singaba ngokunganaki. , akukho ukudlidliza, umsindo ophansi.

1. Isakhiwo se-Monolithic somzimba we-valve: Umzimba we-valve wohlobo lwe-clamp kanye ne-valve ye-flange yohlobo lwe-V-uhlobo lwebhola konke kuyisakhiwo 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 sevalve ye-PTFE esivalayo esithambile noma isihlalo sevalve ye-PTFE esiqinisiwe sisebenza kahle ngokuvala futhi simelana 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 e-shear phakathi kokuvula okumise okwe-V kanye nesihlalo se-valve, kanye nendlela yokugeleza ebushelelezi neyindilinga ye-valve cavity, okuphakathi akulula ukunqwabelana emgodini ongaphakathi, ngakho-ke ilungele i-liquid medium, Ifanele ukulawulwa kwesistimu nge-fiber kanye nemidiya yezinhlayiya 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 uhlobo

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 ekupakini nase-flange kwenziwa ngengcindezi ye-1.1 izikhathi zokucindezela okujwayelekile.Isigxivizo sesihlalo sivivinywa ngokuya ngomehluko omkhulu wengcindezi.Uma umehluko omkhulu wengcindezi ungacacile, cindezela isivivinyo esingu-1.0MPa (ingcindezi yamanzi), lapho umehluko omkhulu wengcindezi ungaphansi kuka-0.6MPa, ukuhlolwa kwenziwa ngengcindezi engu-0.6MPa, kanti okuphakathi kuhlolwe ngamanzi anokugqwala. kanye ne-scale inhibitor.
