ukufakwa kwevalvu yebhola
Imiba efuna ingqwalasela xa kufakelwa iivalvu zebhola
Ukulungiselela ngaphambi kokufakwa
1. Imibhobho ngaphambi nasemva kwevalvu yebhola ilungile. Imibhobho yangaphambili nangasemva kufuneka ibe yi-coaxial, kwaye iindawo zokutywina zeeflanges ezimbini kufuneka zilingane. Umbhobho kufuneka ukwazi ukuthwala ubunzima bevalvu yebhola, kungenjalo umbhobho kufuneka uxhotyiswe ngenkxaso efanelekileyo.
2. Hlanza imibhobho ngaphambi nasemva kwevalvu ukuze ususe amabala eoyile, i-welding slag kunye nazo zonke ezinye izinto ezingcolileyo kwimibhobho.
3. Jonga uphawu lwevalvu yebhola ukuze ufumanise ukuba ivalvu yebhola ayitshintshanga. Yivule ngokupheleleyo kwaye uyivale ivalvu izihlandlo ezininzi ukuqinisekisa ukuba isebenza kakuhle.
4. Susa iindawo zokukhusela kwiiflange ezidibanisayo kuzo zombini iziphelo zevalvu yebhola.
5. Jonga umngxuma wevalvu ukuze ususe ukungcola okunokwenzeka, uze ucoce umngxuma wevalvu. Nokuba yinto encinci engaphandle phakathi kwesihlalo sevalvu nebhola inokonakalisa umphezulu wokutywina kwesihlalo sevalvu.
Faka
1. Faka ivalvu kumbhobho. Nokuba yiphi na isiphelo sevalvu singafakelwa kwisiphelo esingaphezulu. Ivalvu eqhutywa sisiphatho ingafakelwa nakweyiphi na indawo kumbhobho. Kodwa ivalvu yebhola enebhokisi yegiya okanye umqhubi wepneumatic kufuneka ifakwe ime nkqo, oko kukuthi, ifakwe kumbhobho othe tye, kwaye isixhobo sokuqhuba singaphezulu kombhobho.
2. Faka i-gasket phakathi kwe-flange yevalvu kunye ne-flange yombhobho ngokweemfuno zoyilo lombhobho.
3. Iibholithi ezikwiflange kufuneka ziqiniswe ngokulinganayo, ngokulandelelana nangokulinganayo.
4. Qhagamshela umbhobho womoya (xa kusetyenziswa umqhubi womoya).
Ukuhlolwa emva kokufakwa 1. Sebenzisa umqhubi ukuvula nokuvala ivalvu yebhola izihlandlo ezininzi. Kufuneka ibe bhetyebhetye kwaye ingabi nazinzo ukuqinisekisa ukuba isebenza kakuhle.
2. Jonga ukusebenza kokutywina komphezulu we-flange joint phakathi kombhobho kunye ne-ball valve ngokweemfuno zoyilo lombhobho.
Ukulungiselela ngaphambi kokufakwa
1. Imibhobho ngaphambi nasemva kwevalvu yebhola ilungile. Imibhobho yangaphambili nangasemva kufuneka ibe yi-coaxial, kwaye iindawo zokutywina zeeflanges ezimbini kufuneka zilingane.

3. Jonga uphawu lwevalvu yebhola ukuze ufumanise ukuba ivalvu yebhola ayitshintshanga. Yivule ngokupheleleyo kwaye uyivale ivalvu izihlandlo ezininzi ukuqinisekisa ukuba isebenza kakuhle.
4. Susa iindawo zokukhusela kwiiflange ezidibanisayo kuzo zombini iziphelo zevalvu yebhola.
5. Jonga umngxuma wevalvu ukuze ususe ukungcola okunokwenzeka, uze ucoce umngxuma wevalvu. Nokuba yinto encinci engaphandle phakathi kwesihlalo sevalvu nebhola inokonakalisa umphezulu wokutywina kwesihlalo sevalvu.
Faka
1. Faka ivalvu kumbhobho. Nokuba yiphi na isiphelo sevalvu singafakelwa kwisiphelo esingaphezulu. Ivalvu eqhutywa sisiphatho ingafakelwa nakweyiphi na indawo kumbhobho. Kodwa ivalvu yebhola enebhokisi yegiya okanye umqhubi wepneumatic kufuneka ifakwe ime nkqo, oko kukuthi, ifakwe kumbhobho othe tye, kwaye isixhobo sokuqhuba singaphezulu kombhobho.
2. Faka i-gasket phakathi kwe-flange yevalvu kunye ne-flange yombhobho ngokweemfuno zoyilo lombhobho.
3. Iibholithi ezikwiflange kufuneka ziqiniswe ngokulinganayo, ngokulandelelana nangokulinganayo.
4. Qhagamshela umbhobho womoya (xa kusetyenziswa umqhubi womoya).
Ukuhlolwa emva kokufakwa 1. Sebenzisa umqhubi ukuvula nokuvala ivalvu yebhola izihlandlo ezininzi. Kufuneka ibe bhetyebhetye kwaye ingabi nazinzo ukuqinisekisa ukuba isebenza kakuhle.
2. Jonga ukusebenza kokutywina komphezulu we-flange joint phakathi kombhobho kunye ne-ball valve ngokweemfuno zoyilo lombhobho.
