LNG Ultra-low Temperature Valve Foob

Qhov chaw tseem ceeb los xav txog thaum tsim cov foob pob ua ntxaij cryogenic yog geometry. Feem ntau, nws raug nquahu kom siv daim di ncauj nyias nyob rau sab nraud ntawm lub foob kom ua kom yooj yim, thaum lub ntsej muag ntev ntev tuaj yeem pab ua kom qhov chaw sib khi. Cov ntsiab lus xauv lub nplhaib tuaj yeem siv los txo qhov cuam tshuam ntawm shrinkage thiab tiv thaiv lub foob los ntawm rub tawm ntawm cov khoom siv.

Cov ntaub ntawv yog lub hauv paus ntawm lub valve seals thiab nws yog ib qho tseem ceeb los xaiv qhov zoo tagnrho formulation. Polytetraethylene (PTFE) uas muaj ntau yam polymers xws li polyimide thiab ultra-high molecular hnyav polyethylene (UHMWPE) cov ntaub ntawv raug pom zoo rau Seal tsho vim hais tias ntawm lawv cov tshuaj compatibility, tsis muaj kev sib txhuam, abrasion kuj thiab extrusion kuj. Lawv kuj qhia tau zoo sealing tshaj qhov kub thiab txias.

Lub plawv ntawm lub valve zoo yog lub caij nplooj ntoos hlav energizer uas ua rau lub zog nyob ze ntawm lub plhaub los txhawb kev sib khi zoo thiab txawm hnav, txawm tias nws yog lub caij nplooj ntoo hlav, lub caij nplooj ntoos hlav kaw helical canted coil caij nplooj ntoos hlav, lossis lub caij nplooj ntoos hlav helical ribbon, Lub actuator yuav tsum tau chemically tshaj cov xov xwm uas yuav tsum tau ntsib, tiv thaiv corrosion, thiab muaj peev xwm muab muaj zog tab sis ntsuas deflection quab yuam.

Lub caij nplooj ntoos hlav-loaded foob yuav tau txais txiaj ntsig los ntawm kev sib txhuam qis ntawm cov khoom siv hauv caj pas, thiab lub zog quab yuam los ntawm nws lub caij nplooj ntoos hlav yuav pab tiv thaiv kom tsis txhob poob ntawm lub nplhaib yas. Tib lub zog ua kom ntseeg tau tias lub nplhaib yas tuav nruj nruj txawm tias qhov kub qis tshaj plaws, tiv thaiv kev tsis sib xws lossis kev hloov siab ntev ntawm cov khoom siv. Elastomer seals los yog ntim khoom tsis muab cov txiaj ntsig zoo ib yam vim tias lawv tuaj yeem hnav tsis sib xws thiab compression teeb. Hlau ntsaws ruaj ruaj yog ib qho kev xaiv tsis zoo rau cov kev pabcuam dynamic vim kev sib txhuam ntawm cov hlau-rau-hlau tsis zoo ntawm kev sib khi.
