1. Xa ufaka i-valve yesango, kuyimfuneko ukucoca i-cavity yangaphakathi kunye ne-surface yokutywina, khangela ukuba iibholiti zokudibanisa ziqiniswe ngokulinganayo, kwaye ukhangele ukuba ukupakishwa kugxininiswe ngokukhawuleza.
2. Ivalve yesango ivaliwe ngexesha lofakelo.
3. Iivalve zamasango amakhulu amakhulu kunye ne-pneumatic control valves kufuneka zifakwe ngokuthe nkqo, ukwenzela ukuba kungabikho ukuxhatshazwa kwelinye icala ngenxa yobunzima obukhulu be-self-core ye-valve core, eya kubangela ukuvuza.
4. Kukho isethi yemigangatho yenkqubo yokufakela echanekileyo.
5. I-valve kufuneka ifakwe ngokuhambelana nesikhundla esivumelekileyo sokusebenza, kodwa ingqalelo kufuneka ihlawulwe ngokulula ukulungiswa kunye nokusebenza.
6. Ufakelo lwevalve yeglowubhu kufuneka yenze indlela yokuhamba kwayo ihambelane notolo oluphawulwe kumzimba wevalvu.Kwiivalve ezingavulwa rhoqo kwaye zivaliwe kodwa kufuneka ziqinisekise ngokungqongqo ukuba azivuzi kwindawo evaliweyo, zinokufakwa umva ukuze zivalwe ngokuqinileyo ngoncedo loxinzelelo oluphakathi.
7. Xa uqinisa isikrufu soxinzelelo, ivalve kufuneka ibekwimeko evuleke kancinci ukuphepha ukutyumza indawo yokutywina yomphezulu wevalve.
8. Ngaphambi kokubeka i-valve yeqondo lokushisa eliphantsi, uvavanyo lokuvula kunye nokuvala kufuneka lwenziwe kwindawo ebandayo kangangoko kunokwenzeka, kwaye kufuneka ukuba uguquguquke ngaphandle kwe-jamming.
9. Ivalve yolwelo kufuneka icwangciswe ukuze isiqu sevalve sithambekele kwi-engile ye-10 ° ukuya kwindawo ethe tye ukuthintela ulwelo ukuba lungaphumi ngaphandle kwesikhondo sevalve, kwaye ngakumbi, ukunqanda ukuvuza.
10. Emva kokuba inqaba enkulu yokwahlula umoya ibonakaliswe kubanda, qinisa kwangaphambili i-flange yevalve yokudibanisa kanye kwindawo ebandayo ukukhusela ukuvuza kwiqondo lokushisa eliqhelekileyo kodwa ukuvuza kwiqondo lokushisa eliphantsi.
11. Akuvumelekanga ngokungqongqo ukukhwela i-valve stem njenge-scaffold ngexesha lofakelo.
12. Emva kokuba zonke iivalve zikhona, kufuneka zivulwe kwaye zivalwe kwakhona, kwaye zifanelekile ukuba ziguquguquke kwaye zingabambeki.
13. Iivalvu kufuneka zibekwe ngokubanzi phambi kofakelo lombhobho.Umbhobho kufuneka ube yindalo, kwaye isikhundla akufanele sibe nzima.
tsala ukunqanda ukushiya uxinzelelo.
14. Ezinye iivalve ezingezizo ezentsimbi ziqinile kwaye zibhityile, kwaye ezinye zinamandla aphantsi.Xa usebenza, amandla okuvula kunye nokuvala akufanele abe mkhulu kakhulu, ngakumbi angabi nobudlova.Qaphela kwakhona ukuphepha ukungqubana kwento.
15. Xa uphethe kwaye ufaka ivalve, kulumkele ukungqubana nokukrwela iingozi.
16. Xa i-valve entsha isetyenzisiweyo, ukupakishwa akufanele kugxininiswe kakhulu, ukwenzela ukuba kungavuzi, ukwenzela ukuba ugweme uxinzelelo olukhulu kwi-valve stem, eya kukhawulezisa ukugqoka kunye nokukrazula, kwaye kuya kuba nzima vula kwaye uvale.
17. Ngaphambi kokuba i-valve ifakwe, kuyimfuneko ukuqinisekisa ukuba i-valve ihlangabezana neemfuno zoyilo kunye nemigangatho efanelekileyo.
18. Phambi kokufakela isivalo, umphandle wombhobho kufuneka ucocwe ukuze kususwe ukungcola okufana neefayili zentsimbi ukuthintela isitulo sokutywina sesivalo ekubeni sidityaniswe nezinto zangaphandle.
19. I-valve ephezulu yokushisa ifakwe kwiqondo lokushisa.Emva kokusetyenziswa, ukushisa kunyuka, iibholiti zifudumala ukwandisa, kwaye i-gap iyanda, ngoko kufuneka iqiniswe kwakhona.Le ngxaki kufuneka ithathelwe ingqalelo, kungenjalo ukuvuza kuya kwenzeka ngokulula.
20. Xa ufaka i-valve, kuyimfuneko ukuqinisekisa ukuba ulwalathiso lokuhamba kwe-medium, ifom yokufakela kunye nendawo ye-handwheel ihlangabezana nemimiselo.
