Incwadana yemigaqo yofakelo yevalve yebhabhathane yombane

1. Beka ivalve phakathi kweeflange ezimbini ezifakwe ngaphambili (ivalve yebhabhathane yeflange ifuna indawo efakwe ngaphambili yegasket kuzo zombini iziphelo)

2. Faka iibholithi kunye namantongomane kwiziphelo zombini kwimingxunya yeflange ehambelanayo kuzo zombini iziphelo (indawo yegasket yevalve yebhabhathane yeflange kufuneka ihlengahlengiswe), kwaye uqinise amantongomane kancinci ukulungisa ukucaba komphezulu weflange.

3. Lungisa i-flange kumbhobho ngokudibanisa indawo.

4. Susa ivalve.

5. Weld flange ngokupheleleyo kumbhobho.

6. Emva kokuba i-joint welding ipholile, faka i-valve ukuqinisekisa ukuba i-valve inendawo eyaneleyo ehambayo kwi-flange ukukhusela i-valve ingonakaliswa, kwaye uqinisekise ukuba ipleyiti ye-butterfly ine-degree ethile yokuvula (i-valve ye-butterfly valve kufuneka yongeze i-gasket yokutywina); lungisa indawo yevalve kwaye uqinise zonke iibholiti (qaphela ukuba ungajikiji kakhulu); vula ivalve ukuqinisekisa ukuba ipleyiti yevalve inokuvula kwaye ivale ngokukhululekileyo, uze wenze ipleyiti yevalve ivuleke kancinci.

7. Qinisa onke amandongomane ngokulinganayo.

8. Qinisekisa ukuba ivalve inokuvula kwaye ivale ngokukhululekileyo. Qaphela: qiniseka ukuba ipleyiti yebhabhathane ayichukumisi umbhobho.

Qaphela: i-stroke yokuvula nokuvalwa kwendlela yokulawula iye yahlengahlengiswa xa ivalve yebhabhathane yombane ishiya umzi-mveliso. Ukuze uthintele ulwalathiso olungalunganga xa umbane uqhagamshelwe, umsebenzisi kufuneka avule ngesandla kwisiqingatha (50%) isikhundla ngaphambi kokudibanisa umbane wombane, kwaye emva koko ucinezele umbane wokutshintsha umbane ukujonga ukutshintshwa kwaye ukhangele indlela yokuvula i-valve yesalathiso sevili lesalathisi.
