Ntau tus neeg xav paub txog txoj kev ua haujlwm ntawm lub qhov rooj muag muag muag kom thiaj li siv tau lub valve zoo dua.Cov hauv qab no yog txoj kev ua haujlwm thiab kev tshem tawm txoj kev ua txhaum ntawm lub qhov rooj muag muag muag:
Ua ntej, qhib thiab kaw cov kev taw qhia ntawm lub valve, ntau tus neeg ua haujlwm feem ntau ua yuam kev ntawm no, tsuas yog yuav tsum nco ntsoov tias lub valve kaw kev taw qhia yog clockwise.
Qhov thib ob, yog tias lub qhov rooj kaw qhov muag muag tau siv rau hauv cov raj xa dej, cov khoom siv pneumatic hauv lub valve xav tau kev khiav hauj lwm phau ntawv, thiab cov neeg yuav tsum tau siv phau ntawv txoj kev qhib thiab kaw.Yog tias nws yog lub valve loj, lub sijhawm qhib thiab kaw yuav tsum khaws cia ntawm 200 thiab 600 zaug.
Thib peb, qhov qhib thiab kaw quab yuam nyob deb ntawm lub qhov rooj muag muag ntawm lub qhov rooj yuav tsum tau khaws cia nyob rau hauv ib qho chaw, tshwj xeeb tshaj yog kom txuag tau cov neeg ua haujlwm thiab pab txhawb rau ib tus neeg ua haujlwm.Yog hais tias lub zog nyob deb tshaj qhov no, tsawg kawg yog ob mus rau peb tus neeg yuav tsum tau ua tiav lub valve..
Plaub, qhov loj ntawm lub valve yuav tsum yog tus qauv.Thaum tso lub valve, koj yuav tsum xyuam xim rau lub valve ntawm lub rooj vag valve uas tig mus.
Mos sealing rooj vag valveTxoj kev tshem tawm yuam kev:
1. Cov dej ntws tawm ntawm qhov ntim ntawm lub qhov rooj muag muag muag
(1) Lub packing caj pas yog xoob heev, thiab cov txiv ntseej rau nias lub packing caj pas tuaj yeem nruj sib npaug.
(2) Tus naj npawb ntawm cov voj voog ntim tsis txaus, thiab cov ntim yuav tsum tau nce ntxiv.
(3) Kev ntim khoom tsis ua haujlwm vim siv lub sijhawm ntev lossis kev cia khoom tsis raug.Nws yuav tsum tau hloov nrog cov khoom ntim tshiab.Thaum hloov, nws yuav tsum tau muab sau tseg tias cov pob qij txha ntawm txhua lub nplhaib yuav tsum tau hla thiab staggered.
2. Muaj qhov sib txawv ntawm lub rooj vag phaj ntawm lub qhov rooj muag muag thiab lub qhov rooj sib khi ntawm lub rooj zaum valve
(1) Muaj cov av ntawm qhov chaw sib khi, uas tuaj yeem tshem tawm los ntawm kev ntxuav.
(2) Yog tias qhov sealing nto puas lawm, nws yuav tsum tau rov qab hauv av, thiab yog tias tsim nyog, nws tuaj yeem rov ua dua thiab ua tiav.Hauv av sealing nto yuav tsum tiaj tus, thiab nws qhov roughness yuav tsum tsis txhob qis dua 0.4.
3. Cov txiv ntseej xau ntawm qhov sib txuas ntawm lub cev lub cev thiab lub kaus mom ntawm lub qhov rooj muag muag tsis nruj nruj los yog tsis sib npaug, thiab tuaj yeem hloov kho.
(1) Kev puas tsuaj (txoj kab ncaj nraim lossis zawj cov cim, thiab lwm yam) ntawm flange sealing nto yuav tsum raug kho.
(2) Lub gasket puas lawm thiab yuav tsum tau hloov nrog lub gasket tshiab.
4. Mos sealing rooj vag valve qia kis tsis tau yooj yim
(1) Yog tias cov khoom ntim nruj dhau, loosen cov txiv ntoo ntawm lub caj pas kom zoo.
(2) Txoj haujlwm ntawm lub caj pas ntim khoom tsis raug, yog li ntawd lub valve qia yog daig, thiab cov txiv ntoo ntawm lub caj pas ntim khoom yuav tsum tau muab sib npaug sib npaug kom rov qab lub caj pas mus rau qhov qub.
(3) Cov xov ntawm qia thiab qia txiv ntoo raug puas tsuaj thiab yuav tsum tau muab tshem tawm tom qab disassembly.
Mos sealing rooj vag li qub tau siv dav.Mos sealing rooj vag valve, muaj valve, qhib thiab kaw ib feem ntawm mos sealing rooj vag valve yog lub rooj vag, lub zog ntawm lub rooj vag yog perpendicular mus rau cov kev taw qhia ntawm cov kua, lub rooj vag valve tsuas yog qhib thiab kaw tag nrho, thiab tsis tuaj yeem kho lossis throttled.Lub rooj vag phaj muaj ob qhov chaw sealing.Ob qhov chaw sib khi ntawm cov khoom siv feem ntau siv lub rooj vag valve tsim ib lub voj voog.Lub kaum sab xis sib txawv nrog lub valve tsis, feem ntau 50, thiab 2 ° 52 thaum qhov nruab nrab kub tsis siab.
