1. Weld iflange kumbhobho kwaye uphole kwiqondo lobushushu le-ambient phambi kokuba unyusele ivalve kwiflange.Ngaphandle koko, ukushisa okuphezulu okuveliswa yi-welding kuya kuchaphazela ukusebenza kwesihlalo esithambileyo.
2. Imiphetho yeeflange ezidityanisiweyo kufuneka ifakwe kwindawo egudileyo ukuphepha ukonakaliswa kwesitulo esithambileyo ngexesha lofakelo lwevalvu. Umphezulu weflange kufuneka ukhululeke ngokupheleleyo kumonakalo kunye nokuguqulwa, susa konke ukungcola, uthuli kunye nezinto zangaphandle, kwaye ugweme ukuvuza kolwelo kunye nevalve. ujongano lweflange.
3. Coca i-flange kunye nomgodi ongaphakathi wombhobho ukuze ususe ngokupheleleyo i-sputter, isikali kunye nezinye imizimba yangaphandle eshiywe yi-welding.
4. Xa ufaka umbhobho phakathi kweevalve, ukulungelelaniswa ngokuchanekileyo kweziko lemizila yamanzi ephezulu nangaphantsi kubalulekile ekusebenzeni okungenazinkathazo.Indawo engacacanga yeziko eboniswe kuMzobo 1 kufuneka igwenywe.
5. Xa ufaka i-valve, lungisa iibholiti zokubeka phantsi kombhobho kwindawo yokuphakama efanayo ukuze udlale indima exhasayo, kwaye ulungise umgama phakathi kweeflange kude kube ngamacala amabini omzimba we-valve malunga no-6-10 mm ngaphandle. Khumbula ukuba ivalve inokuvulwa kuphela ukusuka kwindawo evaliweyo ukuya kwindawo ye-10 °.
6. Faka iibholithi ezimbini kwibar yesikhokelo esezantsi yevalve kwaye ufake ngokucophelela ukuze indawo yeflange ingonakalisi isihlalo esithambileyo.6.(jonga umfanekiso 2)
7. Emva koko faka ezinye iibholiti ezimbini kwintonga yesikhokelo ngentla kwevalve, uqinisekise indawo echanekileyo esembindini phakathi kombhobho kunye nevalve.
8. Vula ivalve kathathu ukujonga ukuba unxibelelwano phakathi kwepleyiti yevalve kunye neflange ayigudi.
9. Susa iibholithi zokubeka kwaye ubeke zonke iibholithi ezijikeleze umzimba ngokutshintshanisa ukuqinisa i-diagonal (jonga i-Fig. 3 kunye ne-4) de kube i-flange ithinte umzimba.
10. Ukubonelela ngenkxaso yevalve xa ufaka i-actuator ukuphepha ukujija kwentamo yevalve kunye nokunciphisa ukukhuhla phakathi kwevalve kunye nombhobho.
11. Musa ukunyathela intamo yevalve okanye ivili lesandla sevalvu.
12. Musa ukufaka i-DN350 okanye iivalve ezinkulu zijonge phantsi.
13. Musa ukufaka izivalo zebhabhathane ngqo kwiivalvu zokutshekisha okanye kwiimpompo njengoko oku kunokubangela umonakalo xa udibana nepleyiti yesivalo.
14. Musa ukufaka iivalvu kwicala elisezantsi lengqiniba kunye ne-tapering tubing, okanye ulungelelanise iivalvu xa amazinga okuqukuqela etshintsha. Kule meko, kuyacetyiswa ukuba ufakele ivalve kumgama omalunga namaxesha ali-10 ubukhulu begama levalve.
15. Ufakelo lwevalvu kufuneka luthathele ingqalelo ukuba yeyiphi idiski eya kuba nesantya sokuhamba kunye noxinzelelo ngexesha lokuhanjiswa kolwelo.
