Yuav kom daws tau qhov kev tswj valve card los yog blockage phenomenon ntawm hluav taws xob valve yog ntau lub tswv yim?
Raws li ib txwm muaj, tus tswj hwm feem ntau daig lossis thaiv, qhov xwm txheej no ua rau tib neeg cuam tshuam tshwj xeeb, yog li cia lub qhov rooj macro pob valve los pab koj daws koj cov teeb meem!
1) Txoj kev ntxuav
Vuam slag, xeb thiab residue nyob rau hauv lub raj xa dej yuav ua rau txhaws los yog jam nyob rau hauv lub throttling orifice, coj ib feem thiab sib npaug qhov ntawm lub qis valve cover, uas yuav ua rau strain thiab khawb rau ntawm qhov chaw ntawm lub spool thiab qhia nto, thiab indentation ntawm lub valve. sealing nto. Qhov no feem ntau tshwm sim hauv kev ua haujlwm tshiab thiab pib ua haujlwm tom qab kho dua tshiab. Qhov no yog qhov ua tsis tau zoo tshaj plaws. Nyob rau hauv rooj plaub no, yuav tsum tau muab tshem tawm kom huv si, tshem tawm cov slag, xws li sealing nto puas yuav tsum tau av; Nyob rau tib lub sij hawm, LUB PLUG hauv qab yog qhib kom ntws tawm txhua yam khoom seem uas tau poob los ntawm qhov nyiaj tshuav nyiaj li cas mus rau hauv qab lub kaus mom thiab rub tawm txoj kab. Ua ntej muab tso rau hauv kev ua haujlwm, cia lub regulator qhib tag nrho, nruab nrab ntws tom qab lub sijhawm ua haujlwm zoo.
2) Sab nrauv scouring txoj kev
Rau qee qhov yooj yim los nag, muaj cov khoom nruab nrab ntawm cov khoom nruab nrab nrog cov kev cai valve zoo tib yam, feem ntau nyob rau hauv lub throttle, cov lus qhia raug thaiv, tuaj yeem ua cov pa roj thiab cov pa tawm sab nraud ntawm lub hauv qab ntawm lub valve. Thaum lub valve raug thaiv los yog daig, qhib cov roj hluav taws xob sab nraud lossis lub tshuab hluav taws xob, tuaj yeem ua rau lub valve tswj kom ua tiav cov dej ntws tawm, kom ua haujlwm li qub ntawm lub valve.
3) Txhim kho cov yeeb nkab lim txoj kev
Rau me me caliber regulating li qub, tshwj xeeb tshaj yog super me txaus regulating li qub, lub throttle sib txawv me me, yuav tsis muaj me ntsis residue nyob rau hauv nruab nrab. Nyob rau hauv rooj plaub no, nws yog qhov zoo tshaj rau nruab ib lub lim rau ntawm cov yeeb nkab ua ntej lub valve kom ntseeg tau tias qhov kev sib tw ntawm qhov nruab nrab. Regulating valve nrog positioner, positioner tsis ua hauj lwm ib txwm, lub gas choke blockage yog feem ntau txhaum. Yog li ntawd, thaum ua hauj lwm nrog ib tug positioner, nws yog tsim nyog los soj ntsuam nrog rau cov huab cua qhov chaw, thiab ib txwm txoj kev yog rau nruab ib lub cua lim siab txo valve nyob rau hauv lub cua qhov chaw pipeline ua ntej lub positioner.
4) Txhim kho qhov sib txawv ntawm qhov sib txawv
Cov khoom siv xws li qhov nruab nrab los yog ntxuav tawm hauv cov yeeb nkab vuam slag thiab xeb vim dhau lub qhov ncauj qhov ntswg xws li congestion, jam, xws li kev ua txhaum, tuaj yeem hloov qhov sib txawv ntawm qhov sib txawv ntawm qhov loj dua qhov throttle - throttling cheeb tsam ntawm lub qhov rais, qhib lub valve tub ntxhais. thiab lub tes tsho, es tsis yog lub voj voog ntawm lub voj voog vim yog qhov chaw throttling ntawm concentration faib, txhaum tau yooj yim txiav tawm. Yog tias nws yog ib qho, ob lub rooj zaum valve tuaj yeem hloov mus rau lub plunger spool "V-shaped lub qhov ncauj qhov ntswg, lossis rau hauv lub tes tsho valve. Piv txwv li, qee cov nroj tsuag tshuaj muaj ob lub rooj zaum valve feem ntau daig, tom qab pom zoo siv lub tes tsho valve, qhov teeb meem tau daws tam sim ntawd.
5) Qhov nruab nrab scouring txoj kev
Kev siv qhov nruab nrab ntawm tus kheej lub zog ntws tawm, yaug thiab tshem tawm yooj yim los nag, yooj yim rau ntsaws cov khoom, txhawm rau txhim kho kev tiv thaiv kev ua haujlwm ntawm lub valve. Cov kev siv ntau yam yog: ① hloov mus rau ntws kaw hom; ② Txais lub cev valve lub cev; (3) Muab lub throttle orifice rau ntawm qhov chaw siab tshaj plaws erosion. Los ntawm kev siv txoj kev no, kev saib xyuas yuav tsum tau them nyiaj rau kev txhim kho kev yaig tsis kam ntawm cov khoom siv throttle.
6) ncaj qha mus rau lub kaum sab xis txoj kev
Cov dej ntws ncaj qha yog ib qho inverted S ntws nrog txoj kev ntws nyuaj thiab ntau qhov chaw tuag nyob rau hauv cov kab noj hniav sab saud thiab qis, uas muab qhov chaw rau nag lossis daus ntawm nruab nrab. Angular kev twb kev txuas, qhov nruab nrab yog zoo li ntws los ntawm 90 lub luj tshib, zoo scouring kev ua tau zoo, me me tuag cheeb tsam, yooj yim tsim rau hauv ib tug txaus kab. Yog li ntawd, kev siv lub valve ncaj nraim los tsim qhov thaiv me ntsis tuaj yeem hloov mus rau lub kaum sab xis kom lub ℃.
Dab tsi yog qhov ua tau zoo dua li qub hauv cov hluav taws xob hloov kho valve?
Hluav taws xob tswj li qub muaj xws li hluav taws xob tswj npauj npaim valve, hluav taws xob tswj lub pob valve, hluav taws xob tswj lub valve, hluav taws xob tswj lub rooj vag valve, hluav taws xob ib leeg-lub rooj tswj valve, hluav taws xob ob lub rooj tswj valve thiab lub tes tsho hluav taws xob tswj lub valve thiab lwm yam. Pneumatic tswj valve suav nrog pneumatic zaj duab xis tswj valve, pneumatic tswj lub pob valve, pneumatic tswj flange npauj npaim valve thiab pneumatic tswj ntawm npauj npaim valve hom.
Kev hloov hluav taws xob npauj npaim valve tseem hu ua flip valve, yog ib qho yooj yim qauv ntawm lub regulating valve, txuas nrog lub actuator, tuaj yeem siv rau kev siv hluav taws xob qis qis nruab nrab hloov tswj. Nyob rau hauv lub pipeline mas plays lub luag hauj lwm ntawm kev txiav thiab throttling. Qhov qhib thiab kaw ib feem ntawm lub tshuab hluav taws xob npauj npaim valve yog lub phaj zoo li lub disc, uas tig 90 degrees nyob ib ncig ntawm nws tus kheej axis hauv lub valve lub cev, thiaj li ua tiav lub hom phiaj ntawm kev qhib thiab kaw lossis kho. Hluav taws xob hloov pauv npauj npaim valve yog subdivided rau hauv cov pawg hauv qab no:
Hluav taws xob hloov pauv npauj npaim valve (me me txoj kab uas hla): muaj cov yam ntxwv ntawm me me pib torque, loj txaus muaj peev xwm, me me khiav tsis kam, hloov tau yooj yim, thiab lwm yam.
Hluav taws xob hloov pauv npauj npaim valve, hluav taws xob hloov damper: haum rau metallurgical, lub teeb kev lag luam thiab lwm yam lag luam ntawm blast furnace, cua sov rauv, chaw nres tsheb roj thiab lwm lub sijhawm ua haujlwm.
NAC hluav taws xob hloov pauv npauj npaim valve: NAC hluav taws xob hloov pauv npauj npaim valve ua raws li JB / T8528-97 "Technical Conditions of common type valve electric Device".
Muaj ob hom fais fab mov: 220V thiab 380V peb-theem fais fab mov (cov neeg siv tuaj yeem xaiv). Cov khoom yog hom sab nraum zoov thiab nws qib kev tiv thaiv yog IP67.
