I-Petroleum kunye nePetrokhemikhali yeGesi yeNdalo yeGlobhu yeValve eboniswa nguMfanekiso

I-Petroleum kunye nePetrokhemikhali yeGesi yeNdalo yeGlobe iValve

Njengevalve yeglobhu ebaluleke kakhulu, ukutywinwa kwevalve yeglowubhu kukufaka itorque kwisiqu sevalve, kwaye isiqu sevalve sisebenzisa uxinzelelo kumqheba olawulayo kwicala leaxial ukwenza ivalve evulekeyo yokutywina umphezulu ilingane ngokusondeleyo nomphezulu wokutywina. isihlalo sevalvu kunye nokuthintela okuphakathi ekuvuzeni ecaleni komsantsa phakathi kwemiphezulu yokutywina.

Iimbonakalo

Iperi yokutywina yevalve yeglowubhu yenziwe ngumphezulu wokutywina weflap yevalve kunye nomphezulu wokutywina wesitulo sevalvu.Intonga yevalve iqhuba isiphatho sevalve ukuba sihambe ngokuthe nkqo ecaleni kombindi wesitulo sevalve.Kwinkqubo yokuvula kunye nokuvala i-globe, ukuphakama kokuvula kuncinci, okulula ukulungisa ukuhamba, kulungele ukuvelisa nokugcina, kwaye kunoluhlu olubanzi lwezicelo zoxinzelelo.

Xa kuthelekiswa nevalve yesango, eyenye ivelufa yeglowubhu esetyenziswa ngokubanzi, ivalve yeglowubhu ilula ngolwakhiwo kwaye kulula ukuyenza nokuyigcina.Ngokubhekiselele kubomi benkonzo, umphezulu wokutywina wevalve yeglowubhu akukho lula ukunxiba kunye nokukrweleka, kwaye akukho silayidi sinxulumeneyo phakathi kweflap yokufunda kunye nomphezulu wokutywina wesitulo sevalve ngexesha lokuvulwa nokuvalwa kwenkqubo yevalve.Kwimeko apho, i-scratch kwindawo yokutywina incinci, ngoko ke ubomi benkonzo yesibini sokutywinwa buhlala ixesha elide.Kwinkqubo yokuvula ngokupheleleyo kunye nokuvala, ukuhamba kwe-valve flap kuncinci, kwaye ukuphakama kwayo kuncinci.Ukungalungi kohlengahlengiso lweglowubhu kukuba itorque yokuvula nokuvala inkulu kwaye kunzima ukusebenza ngokukhawuleza.Njengoko indlela yokuhamba kumzimba wevalvu inobunzima, ukuhamba kolwelo kunamandla amakhulu, okukhokelela kwilahleko enkulu yamandla olwelo kumbhobho.

Iimbonakalo:

Njengevalve yeglowubhu ebaluleke kakhulu, ukutywinwa kwevalve yeglowubhu kukufaka itorque kwintonga ebanzi, eyenza uxinzelelo kwiphini kwicala le-axial ukwenza indawo elawulayo yokutywina ilingane ngokusondeleyo nomphezulu wokutywina wesihlalo, kunye nokutywinwa. medium isecaleni komphezulu wokutywina ukumisa ukuvuza kumsantsa ophakathi kwawo.

Iperi yokutywina yevalve yeglowubhu yenziwe ngumphezulu wokutywina wendlela yokuthambisa kunye nomphezulu wokutywina wesihlalo sevalve.Intonga yevalve iqhuba iflap yevalve ukuba ihambe ngokuthe nkqo ecaleni kombindi wesitulo sevalve.Ukuphakama kokuvula kuncinci ngexesha lokuvula kunye nokuvala i-valve yeglobhu, ekulula ukuyilungisa ukuhamba, kulungele ukuvelisa nokugcina.

Xa kuthelekiswa nevalve yesango, ivalve yeglowubhu ilula kwisakhiwo kwaye kulula ukuyivelisa kunye nokugcina.Ngokubhekiselele kubomi benkonzo, umphezulu wokutywina wevalve yeglowubhu akulula ukuwunxiba kunye nokuwukrweca, kwaye akukho silawuli sihlobene phakathi kwebhere yevalve kunye nendawo yokutywina yesitulo sevalve ngexesha lenkqubo yokuvula nokuvala.Ngoko ke, ukunxiba kunye nokukrazula kwendawo yokutywina kuncinci, ngoko ke ubomi benkonzo yesibini sokutywinwa buphuculwe.Ukuhamba kwevalve kuncinci kwaye ukuphakama kuncinci ngexesha lokuvula ngokupheleleyo kunye nenkqubo yokuvala ngokupheleleyo i-valve yokusika.

Ukungalungi kwevalve yeglowubhu kukuba itorque yokuvula kunye nokuvala inkulu kwaye kunzima ukufezekisa ukuvulwa nokuvala ngokukhawuleza, kuba umjelo wokuhamba kumzimba olawulayo unobunzima, ukuchasana okunamandla kubangela ilahleko enkulu yamandla olwelo kumbhobho. .

I-Nickel Base Alloy Uxinzelelo oluPhezulu kunye nobushushu beGlobhu yeValve

Iimbonakalo:

Ukuze kuqinisekiswe ukhuseleko kunye nokuthembeka kwevalve, i-valve yomzimba yenziwe nge-nickel base base alloy material, eyenziwe ngesilivere ngokubanzi okanye ixelwe kwaye idibene.Ngenxa yempembelelo yezinto zokwakha, ukulungelelaniswa kwe-cut off kuxhomekeke ekuphumeni okukhulu kunye nokuhla koxinzelelo oluphezulu.Izinto zokutywina zeplate yokulungelelanisa kunye nesihlalo se-valve akufanele nje sixhathise ukubola kunye nokukhukuliseka, kodwa siqinisekise ubunzima kumaqondo aphezulu.Ngoko ke, indawo yokutywina idityaniswe nge-carbide ene-cemented ukuze kuphuculwe ukuxhathisa ukunxiba kunye nokuchasana nokukrala kunye nokuphucula ubomi benkonzo yendawo yokutywinwa.Ukuze kuncitshiswe i-torque yokuvula kunye nokuvala isango, isakhiwo esitsha se-valve sinokwamkelwa.Igumbi eliphakathi lomnyango obanzi lithatha isiseko sokuzitywina, esivumela ukutywinwa koxinzelelo oluphezulu.Okukhona uxinzelelo luphezulu, kokukhona lutywinwa ngcono.Umatshini umiselwe phakathi kwentonga yevalve kunye nekholomu ukukhusela intonga yokulungelelanisa ukuba ingajikelezi, ukwenzela ukuba intonga yokulungelelanisa ihamba kuphela kwaye ihla ngexesha lokuvula okanye inkqubo yokuvala umnyango, ukunciphisa ukuguga kwento, kunye nokuqinisekisa ukuba umsebenzi wokutywina wokupakisha.
