Isakhiwo somzimba wevalvu yesango
1. Ubume bevalve yesango
1. Ubume bevalve yesango
Ubume bomzimba wevalvu yesango bumisela uqhagamshelwano phakathi komzimba wevalve kunye nombhobho, umzimba wevalvu kunye nebhonethi.Ngokubhekiselele kwiindlela zokuvelisa, kukho ukuphosa, ukukhwabanisa, ukudibanisa i-welding, i-casting welding kunye ne-tube sheet welding.
Ngokuqhelekileyo, ukusuka kuqwalaselo lwezoqoqosho, iivalvu ezinobubanzi obuqhelekileyo obulingana okanye obungaphezulu kwe-50mm ziyaphoswa, kwaye ezo ezinobubanzi obungaphantsi kwe-50mm zenziwe ngomgunyathi.Nangona kunjalo, ngophuhliso lwetekhnoloji yanamhlanje yokuphosa kunye neyokwenza, lo mda uye waphulwa ngokuthe ngcembe.Imizimba yeevalvu ezakhiweyo ziye zaphuhla zaya kutsho kwiidayamitha ezinkulu, ngelixa imizimba yevalvu etyhidiweyo ithe chu yaphuhla ukuya kwiidayamitha ezincinci.Naluphi na uhlobo lomzimba wevalve yesango lunokwenziwa ngenkohliso okanye ukuphoswa, ngokuxhomekeke kwiimfuno zomsebenzisi kunye neendlela zokuvelisa ezizezomenzi.
2. Indlela yokuhamba yomzimba wevalvu yesango
Indlela yokuhamba yomzimba wevalve yesango inokwahlulwa ibe ziindidi ezimbini: uhlobo olugcweleyo kunye nodidi oluncitshisiweyo.Ububanzi bomjelo wokuhamba ngokusisiseko bufana nomthamo oqhelekileyo wevalve, oluhlobo olupheleleyo lwe-diameter;ububanzi bomzila wokuhamba buncinci kunomlinganiselo oqhelekileyo wevalve, ebizwa ngokuba luhlobo lwedayamitha encitshisiweyo.Kukho iindidi ezimbini zeemilo zedayamitha ezincitshisiweyo: ukucutha ubukhulu obufanayo kunye nokunciphisa umrhumo ofanayo.Umjelo wokuhamba owenziwe nge-taper luhlobo lokunciphisa i-diameter engekho-uniform.I-aperture ye-inlet end yolu hlobo lwevalve ngokusisiseko ifana ne-dameter ye-nominal, kwaye emva koko iyancipha ngokuthe ngcembe de isihlalo sevalve sincitshiswe sibe sincinci.
Ukusetyenziswa kwejelo lokuhamba kwe-diameter encitshisiweyo (ingaba i-tapered-shaped-shaped-shaped-shaped non-uniform ye-diameter yokunciphisa okanye ukunciphisa i-diameter efanayo), inzuzo yayo kukuba i-valve yenkcazo efanayo inokunciphisa ubungakanani besango, ukuvulwa kunye nokuvala. amandla kunye nomzuzu;i-disadvantage kukuba ukuchasana kokuhamba kuyanda kunye noxinzelelo Ukunciphisa kunye nokusetyenziswa kwamandla kwanda, ngoko i-shrinkage cavity akufanele ibe nkulu kakhulu.Ukunciphisa i-tapered diameter ye-tapered, umlinganiselo we-diameter yangaphakathi yesihlalo sevalve ukuya kwi-diameter ye-nominal ngokuqhelekileyo yi-0.8 ~ 0.95.Kwiivalvu ezincitshisiweyo ezinobubanzi obungaphantsi kwe-250mm, i-diameter yangaphakathi yesitulo sevalve ngokuqhelekileyo inyathelo elinye elisezantsi kunomlinganiselo oqhelekileyo;kwiivalvu ezinobubanzi obuncitshisiweyo ezinobubanzi obuqhelekileyo obulingana okanye obungaphezulu kwe-300mm, idiameter yangaphakathi yesitulo sevalve ikholisa ukuba ngaphantsi kunobubanzi obuqhelekileyo ngamanyathelo amabini.
I-Nortech ngomnye wabavelisi abakhokelayo bevalvu yeshishini e-China kunye nesiqinisekiso somgangatho we-ISO9001.
