Ukuhlolwa kwefektri yeevalvu zebhola

Ukuhlolwa kwefektri yeiivalve zebholayinxalenye ebalulekileyo yokuqinisekisa ukuba umgangatho weevalvu uhlangabezana nemigangatho kunye neemfuno zoyilo. Oku kulandelayo yintshayelelo eneenkcukacha kwiindlela zokuhlola eziqhelekileyo:

1. Ukuhlolwa kwenkangeleko Ukuhlolwa okubonwayo: Umhloli uqwalasela ngqo inkangeleko yesivalo ngeliso lenyama ukujonga ukuba akukho ziphene zokuphosa ezifana neentanda, imingxuma yesanti, kunye nolusu olunzima; khangela ukuba uburhabaxa bomphezulu buhlangabezana neemfuno, nokuba i-coating ifana, ngaphandle kwamanqaku okuhamba, ukuxobula kunye nezinye iziphene. Umlinganiselo womlinganiselo: Sebenzisa izixhobo zokulinganisa (ezifana ne-vernier calipers, micrometers, rula, njl.njl.) ukulinganisa imilinganiselo engundoqo yevalve, efana nobukhulu bomzimba wevalve, ukuphakama, i-inlet kunye ne-outlet flange imilinganiselo, isithuba soqhagamshelo lomngxuma, njl. njl., Ukuqinisekisa ukuba badibana noluhlu lokunyamezela oluchazwe kwimizobo yoyilo.
2. Uvavanyo loxinzelelo Uvavanyo lwamandla
Indawo yovavanyo: Ngokubanzi, amanzi acocekileyo asetyenziswa njengendawo yovavanyo. Kwiivalvu ezingavumelekanga ukuba zidibanise namanzi, umoya ocinezelweyo okanye ezinye iigesi ezifanelekileyo zingasetyenziswa.
Uxinzelelo lovavanyo: Ngokuqhelekileyo i-1.5 amaxesha oxinzelelo lwe-valve, kodwa ingabi ngaphantsi kwe-0.3MPa. Indlela yokuvavanya: Faka ivalve kwisixhobo sokuvavanya, vala i-valve yokuphuma, ngokukhawuleza ukwandisa uxinzelelo kuxinzelelo lovavanyo oluchaziweyo, gcina ixesha elithile (ngokuqhelekileyo imizuzu emi-5 ukuya kwe-10), kwaye ukhangele ukuba kukho ukuvuza okanye ukubila kwindlu yevalve, ibhokisi yokugxusha kunye nezinye iindawo. Ukutywina uvavanyo oluphakathi kovavanyo: Kwiivalvu ezinolwelo lwemidiya, amanzi ahlala esetyenziswa njengendawo yovavanyo; kwiivalvu ezinemithombo yegesi, umoya okanye ezinye iigesi zisetyenziswa.
Uxinzelelo lovavanyo: Ngokuqhelekileyo amaxesha e-1.1 yoxinzelelo lwe-valve. Indlela yokuvavanya: Emva kokuba uvavanyo lwamandla lufanelekile, vula i-valve kwi-angle ethile (ngokuqhelekileyo i-1 / 4-1 / 2 yokuvulwa ngokupheleleyo), ngoko ngokukhawuleza ukwandisa uxinzelelo kuxinzelelo lovavanyo oluchaziweyo, gcina ixesha elithile (ngokuqhelekileyo i-15-30 imizuzu), kwaye ukhangele ukuba indawo yokutywina yevalve iyavuza. Kwiivalvu ezinesakhiwo sokutywinwa okuphezulu, uvavanyo lokutywina oluphezulu luyafuneka.
3. Uvavanyo olusebenzayo
Uvavanyo lokuguquguquka kokutshintsha: Sebenzisa ngesandla ivalve ukujonga ukuba inkqubo yayo yokuvula kunye nokuvala iguquguquka kwaye ingaba kukho nayiphi na i-jamming. Kwimibhobho yombane, i-pneumatic okanye i-hydraulic valves, iimvavanyo zokusebenza ezikude zifunekayo ngokusebenzisa i-actuator ehambelanayo ukujonga ukuchaneka nokuthembeka kwezenzo zabo.
Uvavanyo lweempawu zokuqukuqela: Sebenzisa izixhobo zovavanyo lokuqukuqela ukulinganisa ukuhamba kwevalve kwiindawo ezahlukeneyo zokuvula, zoba ijika leempawu zevalve ukuqinisekisa ukuba iimpawu zokuqukuqela ziyahlangabezana neemfuno zoyilo.
4. Uhlalutyo lwezinto eziphathekayo
Uhlalutyo lwe-Spectral: Sebenzisa i-spectrometer ukuhlalutya izinto zevalve ukumisela ukwakheka kweekhemikhali eziphambili kunye nomxholo wayo ukuqinisekisa ukuba iyahambelana nemigangatho yezinto eziphathekayo echazwe kuyilo.
Uvavanyo lobunzima: Sebenzisa umhloli wobunzima ukulinganisa ixabiso lobunzima beendawo ezahlukeneyo zevalve ukugqiba ukuba ubunzima bezinto eziphathekayo buhlangabezana neemfuno kwaye uqinisekise ukuba i-valve inamandla okwaneleyo kunye nokumelana nokugqoka.
