Ama-valve ovemvane asetshenziswa kakhulu ekuhlinzekweni kwamanzi, ekuhlanzeni amanzi angcolile, nasekuhlanzeni amakhemikhali.Ngoba anomklamo olula, sebenzisa izinsiza kahle, mancane, futhi ashibhile.
Ukufakwa kwe-valve ngendlela efanele kuqinisekisa ukusebenza kahle nokuphila isikhathi eside.Ngaphambi kokufaka i-valve ye-butterfly, inqubo yokufaka kufanele iqondwe.Ngesikhathi sokufakwa, nawe othandekayo kufanele ulandele izinyathelo zokuphepha.
1. Indlela yokufaka i-valve ye-butterfly epayipi?
a)Amathuluzi adingekayo
Ukufaka i-valve uvemvane kudinga amathuluzi ahlukahlukene ukusiza.
-Izinsimbi ziqinisa amabhawodi.
-Izikele ze-torque zihlola ukuthi ukufakwa kungaphakathi kwebanga letorque elifanele.
-Ama-Screwdriver avikela izingxenye ezincane.
-Abasiki bepayipi bakha izikhala zokufakwa kwevalvu uvemvane.
-Amagilavu okuphepha kanye nezibuko zivikela izingozi ezingaba khona.
-Izinga kanye nentambo yokuqondisa: Qinisekisa ukuthi i-valve uvemvane ifakwe ngendlela efanele.
b)Izinto ezidingekayo
-Kudingeka izinto ezithile ukuze kufakwe.
-Ama-Gaskets avala kahle i-valve uvemvane kanye ne-flange.
-Amabhawodi namantongomane avikela ivalve uvemvane epayipini.
-Izimpahla zokuhlanza zisusa udoti epayipini nasezindaweni ze-valve ezidalwe ngesikhathi sokufakwa.
2. Izinyathelo Zokulungiselela
Ukuhlola i-Butterfly Valve
-Ukuhlola i-valve uvemvane ngaphambi kokufakwa kuyisinyathelo esibalulekile.Umkhiqizi uhlola i-valve ngayinye yovemvane ngaphambi kokuthunyelwa.Nokho, izinkinga zisengaphakama.
-Hlola i-valve uvemvane ukuze uthole noma yimuphi umonakalo obonakalayo noma amaphutha.
-Qinisekisa ukuthi i-valve disc ijikeleza ngokukhululekile futhi ayibambeki.
-Qinisekisa ukuthi isihlalo se-valve siphelele.
-Hlola ukuthi usayizi we-valve nokucindezela kufana nemininingwane yepayipi.
Lungiselela Isistimu Yepayipi
Okubaluleke njengokuhlola i-valve uvemvane kuhlola ipayipi.
-Hlanza ipayipi ukuze ususe ukugqwala, udoti nokungcola.
-Hlola ukuhleleka kwemigqa yamapayipi axhumayo.
-Qinisekisa ukuthi ama-flange abushelelezi futhi ayisicaba ngaphandle kwama-burrs.
-Qinisekisa ukuthi ipayipi lingakwazi ukusekela isisindo sovemvane, ikakhulukazi kumavalvu amakhulu.Uma kungenjalo, sebenzisa ubakaki okhethekile.
3. Inqubo yokufaka
a) Ukubeka iValve Butterfly
Misa i-valve uvemvane ngendlela efanele epayipini.
I-valve disc ivuleke kancane ukuze igweme ukuyilimaza noma isihlalo uma ucindezela.Uma kunesidingo, sebenzisa i-flange ekhethekile eyenzelwe ama-valve evemvane ohlobo lwe-wafer.I-valve disc ivuleke kancane ukugwema ukulimaza i-valve disc noma isihlalo se-valve lapho ucindezela isihlalo se-valve.
Hlola umumo
Qinisekisa ukuthi ivalve uvemvane ifakwe umumo ofanele.
Amavalvu uvemvane emaphakathi ngokuvamile amavavu ovemvane aqondiswa kabili.Ama-valve uvemvane e-eccentric ngokuvamile awaqondi ngendlela eyodwa ngaphandle uma kudingeka.Indlela yokugeleza kwendawo ephakathi kufanele ifane nomcibisholo osemzimbeni wevalvu, ukuze kuqinisekiswe umphumela wokuvala wesihlalo sevalvu.
Ukulungisa i-valve ye-butterfly
Faka amabhawodi ezimbotsheni ze-flange zevalve uvemvane kanye nepayipi.Qinisekisa ukuthi i-valve uvemvane igcwele ipayipi.Bese, uwaqinise ngokulinganayo.
Ukuqinisa amabhawodi ngenkanyezi noma inkanyezi enqamulayo (okungukuthi, i-diagonal) kungasabalalisa ukucindezela ngokulinganayo.
Sebenzisa i-torque wrench ukuze ufinyelele itorque eshiwo ibhawudi ngalinye.
Gwema ukuqina ngokweqile, ngaphandle kwalokho kuzolimaza i-valve noma i-flange.
Xhuma idivayisi yokusiza ye-actuator
Xhuma ugesi ekhanda likagesi.Futhi, xhuma umthombo womoya ekhanda le-pneumatic.
Qaphela: I-actuator ngokwayo (isibambo, igiya lezikelemu, ikhanda likagesi, ikhanda elinomoya) ishintshiwe futhi yalungiswa i-valve yovemvane ngaphambi kokuthunyelwa.
Ukuhlolwa kokugcina
-Bheka ukuthi isivalo sevalve uvemvane kanye nepayipi anazo yini izimpawu zokungahambi kahle noma zokulimala.
-Qinisekisa ukuthi i-valve isebenza kahle ngokuvula nokuvala i-valve izikhathi eziningana.Ukuthi i-disc ye-valve ingajikeleza ngokukhululekile ngaphandle kokuvinjelwa noma ukumelana ngokweqile.
-Hlola zonke izindawo zokuxhuma ukuze uthole ukuvuza.Ungenza ukuhlolwa kokuvuza ngokucindezela ipayipi lonke.
-Yenza noma yiziphi izinguquko ezidingekayo ukuze uqinisekise ukusebenza kahle.
Ukuxazulula Izinkinga Ezivamile
Ivalve uvemvane ayivuli noma ivaleke kahle: Hlola izinto ezivimbe ipayipi.Futhi, hlola amandla kagesi e-actuator nomfutho womoya.
Ukuvuza ekuxhumekeni: Hlola ukuthi i-flange yepayipi ayilingani yini.Futhi, hlola ukuthi amabhawodi aqiniswe ngokulinganayo noma axegekile.
Ukufakwa nokugcinwa okufanele kuqinisekisa ukuthi i-valve ye-butterfly isebenza ngokuphumelelayo ezinhlobonhlobo zezicelo.Inqubo yokufaka i-valve uvemvane ihlanganisa izinyathelo ezimbalwa ezibalulekile.Ukuhlanza ngaphambi kokufakwa, ukuqondanisa okufanele, ukulungisa nokuhlola kokugcina kuqinisekisa ukusebenza kahle.Tadisha ngokucophelela futhi ulandele lezi zinyathelo ngaphambi kokuqala ukufaka.Ukwenza kanjalo kungavimbela izinkinga nezingozi.
Phela kunesisho sakudala samaShayina esithi "ukulola ummese akubambezeli ukugawulwa kwezinkuni."
