Ulawulo lokusebenza kwevalvu yevalvu yegasket esebenzayo kunye ne-valve gasket ye-valve A uluhlu lweenkcukacha
Iimfuno zomgangatho wolawulo lwevalvu ziquka ivalve kufuneka ivalwe ngci okanye ivalwe ngokusisiseko; Ukupakishwa kwesitywina se-valve shaft akuvuzi; Ivalve ivuleke kwaye ivale kancinci, iphawula igqibelele. Umsebenzi wemihla ngemihla wolawulo lokusebenza kwevalvu ubandakanya irekhodi evunyiweyo kunye nerekhodi yokusebenza yokuvulwa kwevalvu kunye nokuvala eyona phepha lokusebenza ekuhambeni kweminyaka; Vula kwaye uvale irekhodi yokuhlolwa kwevalvu yeveki ngexesha. Kwivalve yexesha elide ngaphandle kokusebenza kokwenyani, ngokobungakanani benkcazo, kuyimfuneko ukuseta umjikelo wokuhlola owahlukileyo weveki, ngokubanzi * uvule kwaye uvale imisebenzi yomxholo inani lokujika, ukuba ufuna ukuvala ngokupheleleyo umsebenzi wokwenene lumkile.
Ulawulo lokusebenza kwevalvu
I-valve inokuvula kwaye ivale okulungileyo, kungekhona nje ukukhetha imodeli efanelekileyo yevalve, umgangatho omhle wemveliso, ukwakhiwa ngononophelo kunye nokudibanisa, kwaye kufuneka kwakhona iindlela zolawulo olubanzi, unokuba nefuthe lokwenyani "lokuphakamisa amajoni amawaka eentsuku, sebenzisa amajoni ngeli xesha”.
Ulawulo olulungileyo lomsebenzi lubonakaliswa kule miba mithathu ilandelayo: amaxwebhu obugcisa; Ulawulo olubanzi lokusebenza kwevalvu; I-valve ikwimeko entle.
(1) Amaxwebhu obugcisa beevalvu
Idatha yezobuchwepheshe yevalve, kubandakanywa nemiyalelo yokusetyenziswa kwevalve ngaphambi kokunikezelwa; Isiqinisekiso sokuhlolwa kwesivalo emva kokuthenga; Indibano yevalve kunye neenxalenye zekhadi letyala; Irekhodi yokugcinwa kwevalve. Ngenxa yotshintsho ekuhlaleni, ivalve-credit card kufuneka ihlaziywe kwangethuba, ukuze kusekwe inkqubo yolawulo ekrelekrele yeGIS.
(2) Ulawulo lokusebenza kweValve
Iimfuno zomgangatho wolawulo lwevalvu ziquka ivalve kufuneka ivalwe ngci okanye ivalwe ngokusisiseko; Ukupakishwa kwesitywina se-valve shaft akuvuzi; Ivalve ivuleke kwaye ivale kancinci, iphawula igqibelele. Umsebenzi wemihla ngemihla wolawulo lokusebenza kwevalvu ubandakanya irekhodi evunyiweyo kunye nerekhodi yokusebenza yokuvulwa kwevalvu kunye nokuvala eyona phepha lokusebenza ekuhambeni kweminyaka; Vula kwaye uvale irekhodi yokuhlolwa kwevalvu yeveki ngexesha. Kwivalve yexesha elide ngaphandle kokusebenza kokwenyani, ngokobungakanani benkcazo, kuyimfuneko ukuseta umjikelo wokuhlola owahlukileyo weveki, ngokubanzi * uvule kwaye uvale imisebenzi yomxholo inani lokujika, ukuba ufuna ukuvala ngokupheleleyo umsebenzi wokwenene lumkile. Ngenxa yeziphoso eziqhelekileyo ezifunyenweyo kufuneka zibekwe phambili isikimu esikhulu esihambelanayo kunye nesiphakathi sokulungiswa, ukuphathwa ngokufanelekileyo, ngakumbi emva kokuvala i-valve ayikwazi ukuvuleka kufuneka kufane nokugqabhuka kwesondlo ukwenza isisombululo esiphuthumayo.
(3) Imeko yevalufa kakuhle
Imeko yevalve kakuhle ibandakanya udonga lwevalve kakuhle luhlangabezana neemfuno zoyilo; Umngxuma wokugquma umgangatho ophezulu kunye nedocking yomhlaba yomelele; Umsebenzi wokwenene womgama womngxuma wevalve uchanekile; Akukho kungcola namanzi amdaka equleni; Umphezulu wevalvu ngaphandle komhlwa. Ngenxa yokuba i-valve kakuhle yindawo evaliweyo yangaphakathi, kulula kakhulu ukuvelisa i-oksijini eyaneleyo kunye nokwandisa umxholo we-carbon dioxide. Xa abasebenzi bezolondolozo bengakhange baphumeze isivuthelo esinamandla kunye nemilinganiselo yokungenisa umoya ngaphambi kokuba bangene equleni, kulula kakhulu ukubeka ubomi bomntu emngciphekweni. Ukuba iimeko zivuma, imilinganiselo yobugcisa yexesha elide yokuhanjiswa kwerhasi equleni kufuneka ithathelwe ingqalelo kwi-valve ye-valve Wells enkulu. Ngokuba i-valve kakuhle kufuneka ibe ngexesha lokujikeleza, ngokufanelekileyo ukujongana nengxaki yoxinzelelo olungcwatyiweyo, ngenxa yokulahlekelwa kwekhava ye-drain, umonakalo kufuneka ube njengesisombululo esingxamisekileyo sokulondolozwa. Amashishini onikezelo lwamanzi e-Wuhan abeka ngokucacileyo indlela yolawulo lwevalvu kuthungelwano lwemibhobho efana namalungiselelo okugcinwa kwezixhobo, ukusebenzisa inkqubo yokubeka iliso kwisithuthi se-GPS, ukwenza i-valve ilungelelanise kakuhle idatha, ibeka ngokucacileyo phambili imigaqo yokuphunyezwa kunye nemigangatho yovavanyo yokuchongwa kunye nokuhlola, kunye nokomeleza. Amanyathelo olawulo afanele ukujongwa kukhuphiswano kushishino olufanayo. Eli nqaku lisekelwe kwi-original "China Water association yesayensi kunye neTekhnoloji yeKomiti yophando lwekomiti yophando lwekomiti" yomxholo othile, ngokuphakathi emxinwa kwaye yongeza ezinye zeembono zam, ukulungiswa kwethemba elingafanelekanga.
Imisebenzi ye-valve ye-gasket kunye nochungechunge lwe-valve ye-gasket Imveliso ye-valve ye-gasket yi-valve socket flange plate gaskets okanye i-gaskets yevalve enye, ukusetyenziswa kwe-gasket ikakhulu ilele kwi-flange kunye noxinzelelo lokusebenza, ukuba uxinzelelo lokusebenza ngokubanzi alufumaneki kakhulu i-asbestos gasket okanye i-graphite composite gasket, Uxinzelelo lwe-metal winding gasket luninzi kakhulu amagama, ukuba ufuna ukudleka, ubushushu obuphezulu obunganyangekiyo kwisicelo sephedi yefluorine ayiphezulu kakhulu, ukuba yimveliso enokumelana nobushushu obuphezulu, ukusetyenziswa kwephedi yegraphite edityanisiweyo okanye ipad yokujija yesinyithi, ukuba ngumgangatho we-RJ, ukusetyenziswa kwe-ped yentsimbi yentsimbi enye inezicelo ezithile ngexesha elifanayo kunye nezixhobo ezixhasayo zevalve, i-graphite yokuzalisa iringi, ukuba kukho ulwalathiso lokuzitywina (ezifana ne-45 Angle, i-Angle engama-30).
Isiphumo sokutywinwa kwe-valve gasket, ukhetho lwe-gasket ekrwada ngokuhambelana nale migangatho ilandelayo:
1) Phambi kwamanzi okanye ngaphezulu kwe-80 ° umgangatho wamanzi, i-polyethylene PE iplastiki;
2) Phambi kweoli kunye ne-corrosion kunye nesiseko sokushisa okuphezulu okuqhubekayo, kunye ne-metal material gasket;
3) Kwisiseko sokufakelwa kwesandi, ukunciphisa ingxolo kunye nokungeniswa kwe-electrostatic, kunye ne-gasket yamatye.
I-Gasket sisitywina somatshini phakathi kwezinto ezimbini, esetyenziswa ngokubanzi ukunqanda uxinzelelo olusebenzayo, ukhukuliseko, kunye nokwandiswa kwe-thermal yendalo kunye nokuvuza kokuncipha kombhobho phakathi kwezinto ezimbini. Ngenxa yokuba iindawo ezinomatshini azinakwenzeka ukuba zenziwe ngokugqibeleleyo, ukungahambi kakuhle kunokulungiswa ngokusetyenziswa kweegaskets. Iigaskets ngokubanzi zenziwe ngezinto zamaphepha, ezifana neepadi zephepha, iplastiki, i-silicone, izinto zetsimbi, ibhodi ye-cork, i-feelle, i-neoprene, i-rubber ye-nitrile, i-glass fiber okanye i-polymers zeplastiki (ezifana ne-polytetrafluoroethylene). I-gaskets yokusetyenziswa okukhethekileyo kunokwenzeka ukuba ibe nekotoni yamatye.
I-valve gasket yi-valve socket flange plate gaskets okanye i-gaskets yevalve enye, ukusetyenziswa kwe-gasket ikakhulu ilele kwi-flange kunye noxinzelelo lokusebenza, ukuba uxinzelelo lokusebenza ngokubanzi alufumaneki kakhulu i-asbestos gasket okanye i-graphite composite gasket, i-metal winding gasket i-gasket inamandla kakhulu amagama, ukuba ufuna ukuxhathisa umhlwa, ukuchasana nobushushu obuphezulu ayilulo usetyenziso oluphezulu kakhulu lwephedi yeptfe, ukuba kukho into enokumelana nobushushu obuphezulu, Ukusetyenziswa kwephedi edibeneyo yegraphite okanye isinyithi segrafu yokujija iphedi, ukuba ngumphezulu weRJ, isicelo of metal ring pad single has ezinye izicelo ngaxeshanye kunye nezixhobo ezixhasa ivelufa, yi graphite ukuzaliswa ring, ukuba kukho ulwalathiso ukuzitywina (ezifana 45 Angle, 30 Angle).
