Harded Rooj Rooj Zaum thiab Mos Ntsaws Chaw Rooj Tog Qub yog ob hom li qub uas txawv hauv lawv cov tshuab sib tw. Nov yog ib qho kev piav qhia ntawm qhov sib txawv ntawm lawv:
Hard Sealed Gate Valves:
Sealing Mechanism: Hard sealed gate li qub siv hlau-rau-hlau sib cuag rau sealing. Lub rooj vag, uas yog hlau disc, ua rau kev sib cuag nrog lub rooj zaum valve los tsim ib lub foob. Cov hlau saum npoo yog lapped thiab machined los xyuas kom meej lub foob.
Sealing kev ua tau zoo: Hard Solded Rooj Vag cov qub tau muab qib siab ntawm kev sib khi ua haujlwm vim yog cov hlau-to-rau-hlau sib cuag. Lawv yog cov tsim nyog rau kev tuav cov kev siv high-pressure thiab high-temperature, raws li lawv muaj peev xwm tiv taus tej yam kev mob hnyav.
Qhov xwm yeem: Cov ntaub ntawv sib khi hlau ntawm cov rooj zaum sib npaug Lawv tsis tshua muaj kev puas tsuaj los ntawm kev puas tsuaj los yog yaig, ua rau lawv tsim nyog rau cov ntawv thov nrog cov kua dej abrasive lossis siab tshaj tawm.
Kev xau: Lub rooj zaum sib npaug Txawm li cas los xij, lawv yuav xav tau kev saib xyuas ib ntus, xws li rov ua dua lossis rov ua haujlwm ntawm qhov chaw sib khi, kom tswj tau qhov kev sib khi.
Mos Sealed Gate Valves:
Sealing Mechanism: Cov qhov rooj kaw mos mos siv cov khoom tsis yog xim hlau, xws li elastomers lossis polymers, los tsim ib lub foob ntawm lub rooj vag thiab lub rooj zaum valve. Cov ntaub ntawv no muab ib tug resilient thiab saj zawg zog sealing nto.
Sealing Performance: Cov qhov rooj muag muag muag muab kev sib khi zoo, tshwj xeeb tshaj yog rau kev siv qis rau nruab nrab thiab kub. Cov ntaub ntawv mos mos deform thiab ua raws li qhov tsis sib xws ntawm qhov chaw sib khi, muab kev foob zoo.
Durability: Cov ntaub ntawv mos mos siv hauv cov li qub no feem ntau tsis tshua muaj zog piv rau cov hlau-rau-hlau seals. Lawv tuaj yeem degrade dhau lub sijhawm vim raug tshuaj lom neeg, kub kub, lossis kev ntxhov siab. Yog li ntawd, lub neej ntev ntawm lub qhov rooj kaw qhov muag yuav luv dua, thiab lawv yuav xav tau kev saib xyuas ntau zaus lossis hloov.
Cov dej xau: Cov qhov rooj kaw qhov muag mos yog qhov yooj yim rau cov pa tawm piv rau cov qhov rooj kaw ntom ntom. Cov ntaub ntawv mos mos tuaj yeem hnav lossis deform raws sijhawm, ua rau muaj kev sib khi ruaj khov. Txawm li cas los xij, kev nce qib hauv cov khoom siv thev naus laus zis tau txhim kho qhov kev ua tau zoo ntawm cov qhov rooj muag muag muag.
Qhov kev xaiv ntawm cov rooj vag rooj vag lub rooj vag yog li qub txeeg qub teg yog nyob ntawm cov ntaub ntawv uas muaj cov ntaub ntawv tshwj xeeb, xws li cov yam ntxwv kom siab, thiab kev saib xyuas kom zoo.
