Puas yog npauj npaim li qub bidirectional?

Npauj Npaim Valve yog ib hom kev tswj xyuas cov khoom siv nrog lub quarter-tig rotational motion, Nws yog siv rau hauv cov kav dej los tswj lossis cais cov kua dej (kua lossis gases), Txawm li cas los xij, qhov zoo thiab kev ua tau zoo ntawm npauj npaim valve yuav tsum muaj kev sib khi zoo. . Puas yog npauj npaim li qub bidirectional? Feem ntau peb faib cov npauj npaim valve rau hauv Concentric npauj npaim li qub thiab eccentric npauj npaim valve .
Peb yuav tham txog qhov concentric npauj npaim valve bidirectional raws li hauv qab no:

Concentric npauj npaim valve yog dab tsi?

Concentric npauj npaim valve paub raws li qhov chaw zaum lossis xoom-offset npauj npaim li qub, Lawv cov khoom suav nrog: lub cev valve, disc, rooj zaum, qia thiab foob .Cov qauv ntawm concentric npauj npaim valve yog disc thiab lub rooj zaum yog nyob rau hauv nruab nrab ntawm lub valve, thiab lub ncej los yog qia yog nyob rau hauv nruab nrab ntawm lub disc. Qhov no txhais tau hais tias lub disc tig nyob rau hauv lub rooj zaum mos, cov khoom siv lub rooj zaum muaj xws li EPDM, NBR Viton Silicon Teflon Hypalon lossis elastomer.

Yuav ua li cas khiav concentric npauj npaim valve?

Kev tsim kho ntawm tus npauj npaim valve yog qhov yooj yim, muaj peb txoj hauv kev ntawm actuator rau kev khiav hauj lwm: Qiv Kov rau me me, Kab iav lub thawv rau loj li qub kom tswj tau yooj yim dua thiab kev ua haujlwm tsis siv neeg (xws li Hluav Taws Xob thiab Pneumatic Actuators)
Lub npauj npaim valve ua haujlwm los ntawm kev tig lub disk (lossis vane) hauv cov yeeb nkab kom tswj cov dej ntws. Lub disk yog ntsia rau ntawm lub qia uas hla lub cev lub cev, thiab tig lub qia tig lub disk los qhib lossis kaw lub valve, Raws li cov ncej tig, lub disc tig rau qhib lossis ib nrab qhib txoj hauj lwm, tso cai rau cov kua dej ntws tawm. Nyob rau hauv txoj hauj lwm kaw, Ncej rotates disc los thaiv cov ntws tag nrho thiab sealing lub valve.

Puas yog npauj npaim li qub bidirectional?

Bidirectional - txhais tau tias muaj peev xwm tswj tau nyob rau hauv ob qho tib si cov lus qhia, Raws li peb tau tham, lub hauv paus ntsiab lus ntawm kev ua hauj lwm li qub tuaj yeem ncav cuag qhov yuav tsum tau ua .Yog li concentric npauj npaim li qub yog bidirectional, muaj ntau yam zoo siv cov concentric npauj npaim valve.
1 Nws yog kev lag luam ntau dua li lwm hom valve vim lawv cov qauv yooj yim thiab tsawg dua cov ntaub ntawv xav tau rau kev tsim kho. Tus nqi txuag tau tsuas yog pom nyob rau hauv qhov loj valve loj.
2 Ib qho yooj yim khiav lag luam, installation thiab txij nkawm, concenric npauj npaim valve simplicity ua rau nws yooj yim dua thiab sai rau nruab, nws yuav txo tau tus nqi zog, ib qho yooj yim inherently, kev lag luam tsim uas muaj ob peb qhov chaw txav, thiab li no cov ntsiab lus hnav tsawg dua, txo lawv cov txij nkawm. kev xav tau.
3 Lub teeb yuag thiab compact tsim thiab lub ntsej muag me me rau lub ntsej muag dimension ntawm concentric npauj npaim valve, Pab kom nruab thiab siv nyob rau hauv qhov chaw - txwv ib puag ncig, Lawv xav tau qhov chaw tsawg tsawg piv rau lwm hom valve, xws li lub rooj vag lossis lub ntiaj teb li qub, thiab lawv cov compactness simplifies. ob qho tib si installation thiab kev khiav hauj lwm, tshwj xeeb tshaj yog nyob rau hauv densely packed systems.
4 Kev ua yeeb yam nrawm, lub kaum sab xis (90-degree) rotary tsim muab nrog ceev qhib thiab kaw. Cov yam ntxwv no muaj txiaj ntsig zoo hauv cov ntawv thov uas qhov kev teb ceev yog qhov tseem ceeb, xws li hauv kev kaw thaum muaj xwm txheej ceev lossis cov txheej txheem nrog kev tswj xyuas meej. Lub peev xwm qhib thiab kaw sai ua rau lub cev ua haujlwm tau zoo, ua rau cov npauj npaim npauj npaim valve tshwj xeeb tsim nyog rau kev tswj hwm kev khiav thiab kev tswj / tawm hauv cov tshuab uas xav tau lub sijhawm ua haujlwm siab.

Thaum kawg, lub bidirectional npauj npaim valve nrog ob qho tib si kev taw qhia sealing tus yam ntxwv yog vim nws elastic sealing qauv ntawm lub rooj zaum valve thiab npauj npaim disc, xyuas kom zoo sealing tsis hais cov dej ntws kev taw qhia .Qhov kev tsim no txhim khu lub valve lub suab thiab kev ntseeg siab nyob rau hauv bidirectional kua tswj system.
