I-valve yesigaba se-valve yohlelo lwe-gasket uhlobo

I-valve yesigaba se-valve yesigaba se-gasket Uhlobo lwe-valve yokusebenza jikelele Amavalvu esevisi evamile yilawo aklanyelwe ukusebenza okuvamile ngezilinganiso zokucindezela okuphansi esigabeni se-ANSI 150 kuya ku-600 (ububanzi DN16 kuya ku-DN100) kanye nezilinganiso zokushisa ezimaphakathi ukusuka -50 kuye ku-650H (-46 kuya ku-343 c ). Fly imidiya ebolayo kanye nengcindezi evamile yehla ngaphandle kokubangela i-cavitation ne-flash. Amavalvu esevisi ejwayelekile aklanywe ngezinga lokuguquguquka kanye nokuvumelana nezimo ukuze akwazi Asetshenziswa ezimeni ezinzima. Izinto zokwakha zomzimba zicaciswa njenge-carbon steel nensimbi engagqwali. Umfanekiso 1.9 ubonisa inganekwane yamavalvu amabili esevisi evamile, eyodwa esebenza ngesandla neyodwa ezizenzakalelayo. Ama-valve akhethekile okusebenza Amavalvu esevisi akhethekile amavalvu enziwe ngokwezifiso aklanyelwe ukusetshenziswa okukodwa lapho ukusebenza kwenqubo evamile kungalindelekile. Ngenxa yokuklama nokukhiqizwa kwayo okungavamile, ingasetshenziswa kuphela ngaphansi kwemingcele ethile yokusebenza nezimo zokusebenza. Lesi sici ngokuvamile sisetshenziselwa ukubhekana nezinga lokushisa elidingekayo, ubude, noma okuphakathi esivivinyweni sesibili. I-FIG. I-1.10 ikhombisa ivalvu yokulawula eklanywe ngomzimba oklwetshiwe kancane kanye ne-ceramic spool ukuze iphathe izimo zamaminerali ezigugile okuhlanganisa izinhlayiya zesihlabathi nomoya womfutho ophezulu. I-valve yesevisi eqinile I-valve yokusebenza eqinile, enezici ezikhethekile zokusingatha izinto eziguquguqukayo, umjovo wokwehla kwengcindezi ephezulu okuholela e-cavitation enzima, i-flash, ukuvinjelwa noma amazinga aphezulu omsindo. I-valve ingaklanywa kahle ku-spool ye-globe valve. Noma i-disc ekhethekile; Noma amabhola akhethekile angase ahileleke kuma-valve ajikelezayo ukuze anciphise noma avimbele umthelela ngesikhathi sokusebenza. Ngaphezu kwalokho, ama-opharetha noma ama-opharetha okucubungula adinga ama-actuator akhethekile ukuze anqobe amandla enqubo. I-FIG. I-1.11 ikhombisa ivalvu yesevisi eqinile ekwazi ukuphatha i-1100H (593 c) i-calcium ewuketshezi ene-spool eminingi Bamba ukwehla komfutho ophezulu ngebhonethi yokupholisa okukhethekile. I-electro-hydraulic actuator iyakwazi ukukhiqiza u-20,000 lb (889600N) we-thrust. Ama-gaskets e-valve avame ukusetshenziswa ama-gaskets angewona insimbi, ama-semi-metal gaskets nama-gaskets ensimbi. I-gasket engeyona eyensimbi eyaziwa nangokuthi i-gasket, njengeshidi lerabha le-asbestos, irabha, i-ptfe, njll., i-gasket yezinga lokushisa, ingcindezi akuzona izikhathi eziphakeme. I-semi-metal gasket yakhiwe ngezinto zensimbi nezinto ezingezona ezensimbi, njenge-flexible graphite composite gasket, i-gasket emazombezombe, i-gasket eboshwe ngensimbi nokunye. I-semi-metal gasket ithwala ububanzi obubanzi bokushisa nokucindezela kune-non-metal gasket. Wonke ama-gaskets ensimbi enziwe ngensimbi, kufaka phakathi i-waveform, i-tooth shape, i-elliptic, i-octagonal, i-lens pad, i-cone pad njalonjalo. I-Metal gasket yokushisa okuphezulu kanye nezicelo zengcindezi ephezulu. 1 Imibandela yokusebenzisa ama-gasket angewona awensimbi Bheka Ithebula 1-4-1 ukuze uthole izimo zokusebenzisa ama-gasket angewona awensimbi Izimo zesicelo igama lekhodi izinga lokushisa I-MPA izinga lokushisa elisebenzayo ℃ irabha yemvelo nr2.0-50 ~90 chlorinated D irabha cr2.0 -40 ~100D irabha ye-nitrile nbr2.0-30 ~110 irabha ye-styrene butadiene sbr2.0-30 ~100 ethylene propylene rubber epdm2.0-40 ~130 irabha ye-fluorine Viton2.0- 50~200 irabha ye-asbestos3500000000000 ye-asbestos 500000000000000000000000000000000-200 we-asbestos 50000 .t
