(1) Ukuxhatshazwa koxinzelelo oluphezulu: Uxhumo lwe-welding lunokumelana noxinzelelo oluphezulu kwaye lufanelekile kwiqondo lokushisa eliphezulu kunye neemeko zoxinzelelo oluphezulu.

(2) Ukumelana ne-corrosion elungileyo: Uqhagamshelo lwe-welding lunokumelana ne-corrosion elungileyo kwaye lunokusetyenziswa kwiindawo zeendaba eziyingozi kakhulu.

(3) Ufakelo olulula: Uxhulumaniso lwe-welding lwenza lula inkqubo yokufakela kunye nokunciphisa iindleko zobunjineli.

3. Ukukhethwa kwezinto eziphathekayo zevalve yebhola ye-pneumatic edityanisiweyo

3-1. Isixhobo somzimba wevalve

Kubushushu obuphezulu kunye noxinzelelo oluphezulu, ukukhethwa kwezixhobo zomzimba zevalvu kubalulekile. Iivalvu zebhola ezine-pneumatic ezidityanisiweyo zisebenzisa ubushushu obuphezulu kunye noxinzelelo oluphezulu lwezixhobo ezifana nentsimbi engenasici kunye nentsimbi yealloy, enokumelana nokudumba okuhle kunye namandla aphezulu obushushu.

3-2. Izinto zebhola

Ibhola yinxalenye ephambili ye-valve yebhola, kwaye ukukhethwa kwezinto zayo kuchaphazela ngokuthe ngqo ukusebenza kokutywinwa kunye nokuqina kwevalve. I-pneumatic welded i-valve yebhola ye-pneumatic-piece-piece-ball valves isebenzisa izinto zokunxiba ezifana ne-carbide kunye neekeramics ukuqinisekisa ukuthembeka kunye nobomi benkonzo yevalve phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu.

4. Izibonelelo zokusebenza ze-pneumatic welded iivalve zebhola ezinamaqhekeza amathathu

4-1. Ukusebenza kakuhle kokutywinwa

Ivalve yebhola eneziqwenga-ntathu zepneumatic ithatha ubume bebhola edadayo ukuze ifikelele ngokusondeleyo phakathi kwesitulo sevalve kunye nebhola, inciphisa ngokufanelekileyo isantya sokuvuza. Ngaphantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu, ukusebenza kwayo kokutywinwa kugqwesileyo.
