hluav taws xob tswj valve
Tswj valve cov ntsiab lus
Lub valve lub cev yog ua tib zoo nrum, tiv taus siab thiab hnav, thiab ruaj khov.
Ntau cov txheej txheem raug tshuaj xyuas thiab cov kws tshaj lij ua cov kev tshuaj xyuas nruj kom ntseeg tau tias yuav tsis muaj kev puas tsuaj.
Nws tiv taus siab thiab corrosion, muaj kev ua tau zoo, kev ntseeg siab, thiab muaj kev nyab xeeb thiab tsis muaj kev txhawj xeeb. Cov khoom siv tau ntev dua
Cov yam ntxwv ntawm cov hluav taws xob tswj valve
1. Lub servo amplifier txais kev sib sib zog nqus tawm tswv yim tsis zoo, uas tuaj yeem txhim kho qhov tseeb ntawm kev hloov kho tsis siv neeg.
2. Cov neeg siv hluav taws xob tuaj yeem ua ntau hom thiab haum rau 4 ~ 20mA. DC los yog 0 ~ 10mA.
3. Lub adjustable ntau yam yog loj, qhov inherent adjustable ratio yog 50, thiab cov yam ntxwv ntws muaj xws li cov kab ncaj nraim thiab sib npaug feem pua.
4. Lub tshuab hluav taws xob tswj hluav taws xob tuaj yeem tswj tau lub valve ncaj qha los ntawm cov teeb liab tam sim no yam tsis tas yuav muaj lub servo amplifier.
5. Lub valve lub cev yog tsim los raws li lub hauv paus ntsiab lus ntawm cov dej mechanics nrog ib tug tsawg-flow tsis kam ntawm qhov sib npaug ntawm qhov sib npaug, thiab cov rated flow coefficient yog nce los ntawm 30%.
Regulating valve, tseem hu ua tswj valve, yog cov cuab yeej siv hluav taws xob ua haujlwm los hloov cov dej ntws hauv cov txheej txheem txheej txheem. Lub International Electrotechnical Commission (IEC) txhais lub regulating valve [hu ua Control Valve txawv teb chaws] raws li: "Nws muaj xws li ib tug net tivthaiv, ib tug sab hauv valve lub cev tivthaiv uas hloov cov ndlwg tus nqi ntawm cov txheej txheem kua, thiab ib los yog ntau tshaj actuators. Tus actuator yog siv los teb cov teeb liab xa los ntawm kev tswj hwm lub valve yog tsim los ntawm tus actuator thiab lub valve tivthaiv yog lub tshuab tsav tsheb ntawm lub regulating valve thawb pas nrig kom txav mus ib ntus, yog li tsav lub valve tseem ceeb ntawm kev tswj lub valve kom txav mus los Lub valve tivthaiv yog qhov kev tswj ntawm qhov kev tswj lub valve Nws ncaj qha cuam tshuam nrog nruab nrab los ntawm kev hloov pauv ntawm lub actuator laub pas nrig kom hloov qhov throttling cheeb tsam. Lub regulating valve kom ua tiav lub hom phiaj ntawm kev tswj cov li qub feem ntau muab faib ua pneumatic regulating li qub, hluav taws xob tswj li qub thiab hydraulic regulating li qub raws li lawv lub zog. Qhov txawv yog nyob rau hauv lub actuator lawv nruab nrog. Lub pneumatic tswj valve siv compressed cua raws li lub hwj chim qhov chaw thiab yog nruab nrog ib tug pneumatic actuator. Lub tshuab hluav taws xob tswj valve siv hluav taws xob raws li lub zog hluav taws xob thiab nruab nrog lub tshuab hluav taws xob; hydraulic tswj valve siv hydraulic siab raws li lub hwj chim qhov chaw thiab yog nruab nrog ib tug hydraulic actuator. Raws li kev xav tau, lub valve tswj tau tuaj yeem nruab nrog ntau yam khoom siv los ua kom yooj yim siv thiab ua tiav ntau dua hauv kev ua haujlwm. Cov khoom siv no muaj xws li valve positioners, handwheel mechanisms, hluav taws xob converters, thiab lwm yam.
