Kev tswj xyuas kev ua haujlwm ntawm valve gasket efficiency thiab valve gasket A series specifications

Kev tswj hwm kev ua haujlwm ntawm lub valve gasket efficiency thiab valve gasket A series specifications Valve kev tswj kev ua haujlwm zoo yuav tsum muaj xws li valve yuav tsum kaw nruj lossis nruj nruj; Valve ncej foob packing tsis to; Valve qhib thiab kaw maj mam, kos cim tsis zoo. Kev ua haujlwm txhua hnub ntawm kev tswj hwm lub valve suav nrog cov ntaub ntawv pom zoo thiab cov ntaub ntawv ua haujlwm ntawm lub valve qhib thiab kaw daim ntawv ua haujlwm tiag tiag nyob rau xyoo; Qhib thiab kaw cov ntaub ntawv ntawm txhua lub limtiam kev kuaj xyuas lub valve raws sijhawm. Rau lub sij hawm ntev valve yam tsis muaj kev ua haujlwm tiag tiag, raws li qhov loj ntawm qhov tshwj xeeb, nws yog ib qho tsim nyog los teeb tsa lub voj voog tshuaj ntsuam xyuas sib txawv, feem ntau * qhib thiab kaw cov ntsiab lus ntawm cov kev ua ub no, yog tias koj xav kom kaw qhov kev ua haujlwm tiag tiag. ceev faj. Kev tswj hwm kev lag luam valve tuaj yeem qhib thiab kaw tau zoo, tsis yog tsuas yog xaiv cov qauv tsim nyog valve, cov khoom lag luam zoo, kev tsim kho thiab kev sib dhos, thiab tseem xav tau cov txheej txheem kev tswj hwm, tuaj yeem muaj txiaj ntsig zoo ntawm "nce tub rog rau ntau txhiab hnub, siv. cov tub rog ib pliag." Kev tswj xyuas kev ua haujlwm zoo tau cuam tshuam los ntawm peb yam hauv qab no: cov ntaub ntawv thev naus laus zis; Kev tswj hwm kev ua haujlwm valve; Valve zoo nyob rau hauv qhov zoo. (1) Cov ntaub ntawv qhia txog li qub Cov ntaub ntawv ntawm lub valve, suav nrog cov lus qhia rau kev siv lub valve ua ntej xa khoom; Kev soj ntsuam daim ntawv pov thawj ntawm lub valve tom qab yuav khoom; Valve sib dhos thiab qhov chaw ntawm daim npav rho nyiaj; Cov ntaub ntawv kho valve. Nyob rau hauv kev pom ntawm cov kev hloov ntawm lub zej zog, valve-credit card yuav tsum tau hloov kho nyob rau hauv lub sij hawm, thiaj li mus tsim GIS ntse tswj system. (2) Kev tswj hwm kev lag luam valve Valve kev tswj hwm kev ua haujlwm zoo suav nrog valve yuav tsum kaw nruj lossis nruj nruj; Valve ncej foob packing tsis to; Valve qhib thiab kaw maj mam, kos cim tsis zoo. Kev ua haujlwm txhua hnub ntawm kev tswj hwm lub valve suav nrog cov ntaub ntawv pom zoo thiab cov ntaub ntawv ua haujlwm ntawm lub valve qhib thiab kaw daim ntawv ua haujlwm tiag tiag nyob rau xyoo; Qhib thiab kaw cov ntaub ntawv ntawm txhua lub limtiam kev kuaj xyuas lub valve raws sijhawm. Rau lub sij hawm ntev valve yam tsis muaj kev ua haujlwm tiag tiag, raws li qhov loj ntawm qhov tshwj xeeb, nws yog ib qho tsim nyog los teeb tsa lub voj voog tshuaj ntsuam xyuas sib txawv, feem ntau * qhib thiab kaw cov ntsiab lus ntawm cov kev ua ub no, yog tias koj xav kom kaw qhov kev ua haujlwm tiag tiag. ceev faj. Rau cov kev ua txhaum ntau pom yuav tsum tau muab tso rau hauv cov txheej txheem kho qhov loj thiab nruab nrab, ua haujlwm kom zoo, tshwj xeeb tshaj yog tom qab kaw lub valve tsis tuaj yeem qhib yuav tsum zoo li kev kho tawg kom ua tiav kev daws teeb meem kub ntxhov. (3) Valve zoo mob Lub valve zoo muaj xws li lub valve zoo phab ntsa raws li tus qauv tsim; Manhole npog zoo thiab hauv av docking zoo; Kev ua haujlwm tiag tiag ntawm lub valve qhov nrug yog qhov tseeb; Tsis muaj av thiab dej khib nyiab hauv qhov dej; Valve nto tsis xeb. Vim tias lub qhov dej zoo yog qhov chaw kaw hauv tsev, nws yooj yim heev los tsim cov pa oxygen tsis txaus thiab ua kom cov pa roj carbon dioxide ntau ntxiv. Thaum cov neeg ua haujlwm saib xyuas tsis ua lub tshuab ua kom muaj zog thiab ntsuas cua ua ntej nkag mus rau hauv qhov dej, nws yooj yim heev ua rau muaj kev phom sij rau tib neeg lub neej. Yog hais tias tej yam kev mob tso cai, cov kev ntsuas ntawm lub sij hawm ntev thermal convection ntawm cov roj nyob rau hauv lub qhov dej yuav tsum tau coj mus rau hauv tus account nyob rau hauv loj txoj kab uas hla valve Wells. Rau lub valve zoo yuav tsum tau nyob rau lub sij hawm saib xyuas, kom zoo nrog rau qhov teeb meem ntawm faus siab, rau qhov ntws cover poob, kev puas tsuaj yuav tsum tau raws li kev kho mob tawg thaum muaj xwm ceev. Wuhan cov chaw tsim khoom siv dej kom meej meej tau muab tso rau hauv kev tswj hwm lub valve hauv cov kav dej sib txuas zoo li cov kev tswj xyuas cov cuab yeej siv, siv GPS lub tsheb saib xyuas, tsim cov ntaub ntawv valve zoo sib koom ua ke, kom meej meej tso rau hauv kev siv cov cai thiab kev soj ntsuam cov qauv ntawm kev txheeb xyuas thiab tshuaj xyuas, thiab ntxiv dag zog rau. kev tswj hwm kev ntsuas tsim nyog rau kev siv rau kev sib tw hauv tib lub lag luam. Tsab ntawv xov xwm no yog ua raws li tus thawj "China Water Association science and Technology Committee pipeline professional research report" ntawm cov ntsiab lus tshwj xeeb, nqaim nqaim thiab ntxiv qee qhov ntawm kuv qhov kev xav, kev cia siab kho tsis raug. Valve gasket muaj nuj nqi thiab valve gasket series Ib yam khoom specification valve gasket yog valve socket flange phaj gaskets los yog ib tug valve gaskets, gasket daim ntawv thov mas yog nyob rau hauv lub flange thiab lub siab ua hauj lwm, yog hais tias kev ua hauj lwm siab tsis muaj siab asbestos gasket los yog graphite composite gasket, hlau winding gasket siab yog cov lus ntau dhau lawm, yog tias koj xav tau corrosion, kub resistant plaub fluorine ncoo daim ntawv thov tsis siab dhau, Yog hais tias nws yog ib tug kub kub resistant khoom, daim ntawv thov ntawm graphite composite ncoo los yog hlau khoom graphite winding ncoo, yog nws yog RJ nto, daim ntawv thov ntawm hlau nplhaib ncoo ib leeg muaj qee qhov kev siv tib lub sijhawm nrog lub valve txhawb nqa, yog graphite filling nplhaib, yog tias muaj kev taw qhia nws tus kheej sealing (xws li 45 Lub kaum ntse ntse, 30 Lub kaum ntse ntse). Valve gasket sealing nyhuv, gasket raw khoom xaiv raws li cov qauv hauv qab no: 1) Nyob rau hauv lub xub ntiag ntawm dej los yog tshaj 80 ° dej tus qauv, polyethylene PE yas; 2) Nyob rau hauv lub xub ntiag ntawm cov roj thiab corrosion thiab qhov chaw ntawm qhov kub thiab txias, nrog rau cov khoom siv hlau gasket; 3) Nyob rau hauv qhov chaw ntawm lub suab rwb thaiv tsev, suab nrov txo thiab electrostatic induction, nrog pob zeb gasket. Gasket yog lub tshuab foob nruab nrab ntawm ob yam khoom, uas feem ntau yog siv los tiv thaiv kev ua haujlwm siab, yaig, thiab ntuj thermal expansion thiab contraction to ntawm cov kav dej ntawm ob yam khoom. Vim tias qhov chaw machined tsis zoo li yuav raug tsim los ua kom zoo, qhov tsis sib xws tuaj yeem kho tau los ntawm kev siv cov gaskets. Gaskets feem ntau yog ua los ntawm cov ntaub ntawv, xws li cov ntaub ntawv, yas, silicone, hlau cov ntaub ntawv, cork board, xav, neoprene, nitrile roj hmab, iav fiber ntau los yog yas polymers (xws li polytetrafluoroethylene). Gaskets rau kev siv tshwj xeeb yuav muaj pob zeb paj rwb. Valve gasket yog valve socket flange phaj gaskets los yog ib lub valve gaskets, gasket daim ntawv thov mas yog nyob rau hauv lub flange thiab ua hauj lwm siab, yog hais tias kev ua hauj lwm siab tsis muaj siab asbestos gasket los yog graphite composite gasket, hlau winding gasket siab yog cov lus ntau dhau lawm, yog Koj xav kom corrosion kuj, tsis kam mus rau kub tsis dhau daim ntawv thov ntawm ptfe ncoo, yog hais tias ib yam dab tsi yog ib tug siab tiv taus kub, daim ntawv thov ntawm graphite composite ncoo los yog hlau khoom graphite winding ncoo, yog hais tias nws yog lub RJ nto, daim ntawv thov ntawm hlau nplhaib ncoo ib leeg muaj qee qhov kev siv tib lub sijhawm nrog lub valve txhawb nqa, yog graphite filling nplhaib, yog tias muaj kev taw qhia nws tus kheej sealing (xws li 45 Lub kaum ntse ntse, 30 Lub kaum ntse ntse).
