Feem ntau ua rau thiab txoj kev kho ntawm valve phaj tsis ua haujlwm muaj xws li cov ntsiab lus hauv qab no:
Ua rau tsis ua hauj lwm
Lub qia valve tsis hloov pauv los yog daig: Qhov no tuaj yeem tshwm sim los ntawm kev ntim khoom nruj heev, cov khoom ntim tsis tau muab tso rau hauv lub thawv ntim raws li cov lus qhia tshwj xeeb, lub qia valve thiab lub valve qia bushing siv tib yam khoom, cov khoom siv tsis raug. xaiv, tsis txaus clearance nruab nrab ntawm lub valve qia thiab lub bushing, lub valve qia dabtsi yog khoov, los yog cov xov nto roughness tsis tau raws li qhov yuav tsum tau.
Sealing nto to: Qhov no tej zaum yuav tshwm sim los ntawm kev puas tsuaj rau lub sealing nto (xws li indentation, abrasion, los yog tawg hlau nyob rau hauv nruab nrab), av uas txuas ntawm lub sealing nto los yog tsis zoo kev twb kev txuas ntawm lub sealing nplhaib.
Padding to: Qhov no tej zaum yuav tshwm sim los ntawm lub ntim siab phaj tsis tau nias kom nruj, lub ntim tsis txaus, lub ntim tsis ua hauj lwm vim tsis zoo cia, lub valve qia roundness tshaj cov kev cai, los yog lub valve qia nto muaj khawb, engraved kab, burrs. thiab roughness, ntau yam, cov qauv loj lossis qhov zoo ntawm cov ntim tsis tau raws li qhov yuav tsum tau ua, thiab lwm yam.
Valve lub cev to: Qhov no tej zaum yuav tshwm sim los ntawm cov xuab zeb qhov los yog tawg nyob rau hauv lub valve lub cev thiab lub cev valve thaum kho vuam.
Lub valve tub ntxhais thiab qia yog sib cais, ua rau qhov hloov tsis tau. Qhov no tej zaum yuav tshwm sim los ntawm kev kho tsis raug, corrosion ntawm lub valve core thiab valve qia sib koom ua ke, lub zog ntau dhau ntawm kev hloov ua rau kev puas tsuaj rau lub valve core thiab valve qia, loosening ntawm lub valve tub ntxhais nres gasket, hnav ntawm qhov sib txuas, thiab lwm yam.
Cov kab nrib pleb muaj nyob hauv lub hauv paus valve thiab lub rooj zaum. Cov no tuaj yeem tshwm sim los ntawm qhov tsis zoo ntawm qhov vuam ntawm qhov sib koom ua ke, qhov kub thiab txias sib txawv ntawm ob sab ntawm lub valve, lossis lwm yam.
Txoj kev kho mob
Txhim kho kev ua haujlwm, zam kev quab yuam ntau dhau, thiab tshawb xyuas qhov txwv thiab cov khoom siv tiv thaiv ntau dhau.
Rau qhov teeb meem ntawm kev sib hloov tsis yooj yim los yog daig valve qia, koj tuaj yeem kho qhov ntim clamping quab yuam, hloov cov khoom tsim nyog, hloov lub valve qia lossis bushing, kho lossis hloov cov xov nto, thiab lwm yam.
Rau qhov teeb meem ntawm sealing nto to, koj tuaj yeem rov sib tsoo lub sealing nto, tshem tawm cov av ntawm lub sealing nto, hloov lub foob, thiab lwm yam.
Rau qhov teeb meem ntawm qhov ntim ntawm qhov ntim, koj tuaj yeem rov ua kom nruj lub pob ntim phaj, ntxiv lossis hloov cov ntim, kho lossis hloov lub valve qia, thiab lwm yam.
Rau qhov teeb meem ntawm valve lub cev to, koj tuaj yeem kho lossis hloov lub valve lub cev, kho lossis khawb cov kab nrib pleb, xyuas thiab kho qhov nro uas yuav tshwm sim los ntawm kev kho vuam, thiab lwm yam.
Rau qhov teeb meem ntawm lub valve tub ntxhais thiab valve qia sib cais, koj tuaj yeem tshawb xyuas thiab kho cov khoom puas, hloov cov khoom siv corrosion-resistant gate qia, tsis txhob muaj zog ntau dhau thaum qhib thiab kaw lub valve, thiab lwm yam.
Kev tawg ntawm lub hauv paus valve thiab lub rooj zaum valve tuaj yeem kho tau los ntawm vuam, kev kho cua sov raws li kev cai, lathing, sib tsoo, thiab lwm yam.
Cov ntaub ntawv saum toj no tsuas yog siv rau kev siv xwb. Txoj kev kho tshwj xeeb yuav tsum raug txiav txim thiab xaiv raws li qhov xwm txheej. Thaum ua haujlwm nrog valve phaj tsis ua haujlwm, koj yuav tsum xav txog kev nyab xeeb thiab ua raws li cov txheej txheem kev khiav hauj lwm thiab kev ceev faj.
