Qhov txawv ntawm Trunnion Mounted & Floating Ball Valves:
Trunnion li qub tswj kev kub siab / loj bore nrog pob zeb- khov kho siv lubtaag pob & floating rooj. Floating li qub yeej nyob rau hauv qis / nruab nrab siab / me bore nrog lawvtxav pob & cov rooj zaum ruaj khov.
Cov ncauj lus kom ntxaws:
Pob Fixation & Sealing Txoj Cai:
Lub tog raj kheej Valve:
Qauv:Pob yogrigidly txhawb sab saum toj thiab hauv qab los ntawm cov khoom trunnions- nws tsis txav.
Sealing: Cov rooj zaum "floating"(feem ntau lub caij nplooj ntoos hlav-loaded). Kaw siabthawb lub rooj zaum tawm tsam lub pob ruaj khov. Siab dua=nruj dua.
Floating Valve:
Qauv:Pob yogtsuas yog txuas los ntawm qia (nrog kev ua si), tsis txhawb lwm yam- pob nws tus kheejntab / txav.
Sealing: Cov rooj zaum yog tsau nyob rau hauv lub valve lub cev. Kaw siabthawb lub pob ntab tawm tsam lub rooj zaum hauv qab. Siab dua=pob thawb hnyav dua.
Ua haujlwm Torque:
Trunnion Valve: qis & ruaj khov torque.Fixed pob txhais tau tias kev sib txhuam feem ntau yog los ntawm cov rooj zaum. Torque nce maj mam nrog siab. covZoo tagnrho rau qhov loj me / siab siab thiab me actuators.
Floating Valve: Siab dua & Siab-Sensitive Torque.Yuav tsum kov yeej kev sib txhuam los ntawm pob crushing tiv thaiv lub rooj. Torqueskyrockets nyob rau hauv siab siab / loj loj, xavloj (costlier) actuators. Kev cuam tshuam tsawg dua ntawm qhov me me / tsis tshua muaj siab.
Siab & Loj Muaj Peev Xwm:
Trunnion Valve: Huab tais siab -Pressure/Large-Bore.Ua rau siab siab (Class 600, 900, 1500, 2500+) thiab loj bore (DN100 / NPS 4 "+).Structurally robust, siab ntseeg.
Floating Valve: Master of Low/Medium-Pressure/Me-Boe.Qhov zoo tshaj plaws rau qhov siab qis / nruab nrab (tsawg dua lossis sib npaug rau Chav Kawm 600, feem ntau Tsawg dua lossis sib npaug rau DN50 / NPS 2 "). Kev kub siab / qhov loj me yuav muaj kev cuam tshuam pob, lub rooj puas tsuaj, thiab lub zog ntau dhau.
Kev taw qhia sealing:
Trunnion Valve: Feem ntau Bidirectional.Reliably seals tsis hais txog ntawm kev khiav dej num (tsim tseeb tsim).
Floating Valve: Feem ntau Unidirectional.Relies ntawm ntws thawb pob tawm tsamnqes havrooj. Rov qab sealing tsis muaj zog.
Complexity & Nqi:
Trunnion Valve: Ntau qhov nyuaj, Ntau qhov chaw.Trunnions, bearings, caij nplooj ntoos hlav zaum =tus nqi tsim khoom ntau dua(tshwj xeeb yog qhov me me). Feem ntau loj dua / hnyav dua.
Floating Valve: Yooj yim, compact, tsawg qhov chaw. Tsawg tus nqi tsim khoom(qhov txiaj ntsig tseem ceeb ntawm qhov me me / tsis tshua muaj siab). Qhov hnyav dua.
