Indlela yokwenza ugcino lwesiqhelo lweiivalve? Iivalve ezizenzekelayo zi-pneumatic, hydraulic kunye nombane. Ukuhlolwa kokugcinwa rhoqo kukubona ukuba amandla abo aphantsi okanye aphezulu kakhulu, okuya kuchaphazela ukusebenza okuqhelekileyo kwevalve. Okwesibini kukujonga izixhobo ezincedisayo zomonakalo okanye ukuvaleka. Kukwakho ukujonga ukuba ingaba umbhobho wamandla uvuzile okanye wophukile, nokuba ujongano lukhululekile na.
Kukho uxinzelelo lokucoca umoyaiivalve zokunciphisa, iivalve ze-solenoid, ii-positioners kunye nezinye izixhobo. Emva koko kukho isenzo se-actuator yevalve, nokuba isilinda sevalve iyavuza okanye ixingile, kwaye nesiqu sevalve sicimile. Nokuba isihlalo sevalve sidlekile kwaye kukho ukuvuza kwangaphakathi okanye ukuvuza kwangaphandle. Iivalve ezingasebenziyo zisebenza ngesandla, kodwa akukho mandla kunye neengxenye ezincedisayo, ezinye iintsilelo ziyafana.
Ezinye iingongoma ekufuneka ziqwalaselwe kusetyenziso lwemihla ngemihla:
1. Iivalvu zahlulwe ikakhulu zibeiivalvu zeglowubhu,iivalve zebhola, iivalve zesango, iivalve zebhabhathane,ivalve yeplagis, njl. Emva kokuba i-valve ifakwe kwaye isetyenziswe, igrisi okanye i-molybdenum disulfide kufuneka isetyenziswe kwimicu ye-valve stem kunye neebholiti, ezinokubonelela ngefuthe elihle lokuthambisa. Ngexesha elifanayo, inokuphinda ihlukanise indawo ye-acid-base kwaye isebenze njengoluhlu olukhuselayo.
2. Gcina ivalve icocekile, ngakumbi kwiivalvu zangaphandle. Ukuba kuyimfuneko, yongeza i-valve kunye ne-flange yokukhusela izigqubuthelo.
3. Musa ukusebenzisa i-brute force xa uvula naxa uvala ivalve, nokuba usebenzisa i-afterburner, awukwazi ukusebenzisa amandla agqithisileyo. Umzekelo, ukusebenzisa amandla amaninzi kunokonakalisa ngokulula i-gasket yokutywina kwintloko yevalvu yevalvu yokumisa.
4. Ukutshatisa ivalve kufuneka kutshatiswe, umzekelo, ivili lesandla kunye nevalve kufuneka zitshatiswe, kungenjalo indawo ephezulu yesikhondo sevalvu iya kuba ngqukuva kwaye imtyibilizi.
5. Musa ukubeka izinto ezinzima okanye ukunyathela ivalve.
6. Kukho ukuvuza kumzimba wevalvu, ekufuneka kujongwana nawo ngokwendawo yokuvuza. Ngokomzekelo, ukuba indawo yokupakisha i-valve yokuvala iyavuza, i-bolt ye-gland yokupakisha ingalungiswa ngokufanelekileyo, kwaye amacala amabini anokulinganisela.
Ukugcinwa kwemihla ngemihla ngokubanzi, ukuba kukho ingxaki kuloo nxalenye, unokumisela iyeza elifanelekileyo ngaphandle kokuchithwa okukhulu. Ngamanye amaxesha kuyimfuneko ukutshintsha iindawo okanye izitywina okanye ukubuyisela igrisi, njl., Ngokuqhelekileyo ucoce kwaye ugcwalise i-lubricant ngexesha, elinokwandisa ubomi benkonzo kunye nokukhusela ilanga nemvula.
