NUM 1

1. Nlele ike nke pneumatic ball valve ga-anwale ya na bọọlụ ọkara oghe.

1.1 Titan sere n'elu bọl valvụ tightness ule: valvụ bụ na a ọkara-emeghe ọnọdụ, ule ọkara na-ẹkenam na otu njedebe, na ndị ọzọ na-emechi na-emechi; a na-agba bọl ahụ ọtụtụ ugboro, a na-emeghekwa njedebe mechiri maka nyocha mgbe valvụ ahụ nọ na steeti mechiri emechi, na arụmọrụ akara na mbukota na gasket ahụ. Agaghị adị ehi mmiri. E webatara usoro nyocha ahụ site na nsọtụ nke ọzọ wee mee nyocha ahụ ọzọ.

1.2 Titan Trunnion Mounted Ball bọọlụ tightness ule: Tupu ule ahụ, bugharia bọl ahụ na-enweghị ibu ọtụtụ oge, a na-emechi valvụ a kapịrị ọnụ, a na-ewebata usoro nyocha ahụ site n'otu njedebe ruo uru a kapịrị ọnụ; lelee arụmọrụ akara nke ntinye ahụ na nlele nrụgide. Izi ezi nke nlele nrụgide bụ 0.5 ruo 1 na oke ahụ bụ 1.6 ugboro nrụgide ule. Na oge a kapịrị ọnụ, ọ bụrụ na enweghi nkụda mmụọ, ọ ruru eru; mgbe ahụ, a na-ewebata usoro nyocha ahụ site na nsọtụ nke ọzọ, a na-emegharị ule dị n'elu. Mgbe ahụ, valvụ ahụ nọ na ọkara-emeghe, e mechiri ngwụcha ya, oghere dị n'ime ya juputara na ọkara, a na-enyocha ngwongwo na gasketị n'okpuru nrụgide ule, ọ ga-enwerịrị nkwụsị.
