ukufakwa kwevalvu yebhola
Izinto ezidinga ukunakwa ekufakweni kwama-ball valve
Ukulungiselela ngaphambi kokufakwa
1. Amapayipi ngaphambi nangemva kwevalvu yebhola aselungile. Amapayipi angaphambili nangemuva kufanele abe yi-coaxial, futhi izindawo zokuvala zama-flange amabili kufanele zilingane. Ipayipi kufanele likwazi ukuthwala isisindo sevalvu yebhola, ngaphandle kwalokho ipayipi kumele lifakwe ukwesekwa okufanele.
2. Hlanza amapayipi ngaphambi nangemva kwevalvu ukuze ususe amabala kawoyela, i-welding slag kanye nakho konke ukungcola okusemapayipini.
3. Hlola uphawu lwevalvu yebhola ukuze uthole ukuthi ivalvu yebhola iphelele. Vula futhi uvale ivalvu ngokugcwele izikhathi eziningana ukuqinisekisa ukuthi isebenza kahle.
4. Susa izingxenye ezivikelayo kuma-flange axhumanisayo kuzo zombili izinhlangothi zevalvu yebhola.
5. Hlola imbobo yevalvu ukuze ususe ukungcola okungenzeka, bese uhlanza imbobo yevalvu. Ngisho nezinto ezincane ezingaphandle phakathi kwesihlalo sevalvu nebhola zingalimaza indawo yokuvala isihlalo sevalvu.
Faka
1. Faka ivalvu epayipini. Noma yikuphi ukuphela kwevalvu kungafakwa ekugcineni okuphezulu. Ivalvu eqhutshwa yisibambo ingafakwa kunoma iyiphi indawo epayipini. Kodwa ivalvu yebhola enebhokisi legiya noma umshayeli we-pneumatic kufanele ifakwe iqonde, okungukuthi, ifakwe epayipini elivundlile, futhi idivayisi yokushayela ingaphezu kwepayipi.
2. Faka i-gasket phakathi kwe-flange ye-valve ne-flange yepayipi ngokwezidingo zomklamo wepayipi.
3. Amabhawodi eflange adinga ukuqina ngokulinganayo, ngokulandelana nangokulinganayo.
4. Xhuma ipayipi lomoya (uma kusetshenziswa umshayeli womoya).
Ukuhlolwa ngemva kokufakwa 1. Sebenzisa umshayeli ukuvula nokuvala ivalvu yebhola izikhathi eziningana. Kufanele iguquguquke futhi ingabi nokuma ukuze kuqinisekiswe ukuthi isebenza kahle.
2. Hlola ukusebenza kokuvala kwendawo ehlanganisiwe ye-flange phakathi kwepayipi kanye ne-ball valve ngokuya ngezidingo zomklamo wepayipi.
