Valve yo kugenzura yo mu bwoko bwa Amerika yo gushyira mu bikorwa
Ibindi bicuruzwa
I. Imiterane y’ubwubatsi
Valve yo gufata (valve yo gufata) ni valve yo gufata ikoreshwa cyane, ikoreshwa cyane cyane kugirango uhuze cyangwa gufata ibintu byo mu muryango. Inyungu zikuru za valve yo gufata ni:
1. Ugereranije na valve ya gate, valve yo gufata ifite imiterane y’ubwubatsi iroroha, kandi yo gukora no kuyobora byoroha.
2. Ibikoresho byo gufata ntibishobora kwangirika cyangwa kwandura, kandi gufata neza, kandi igira ubuzima bwiza.
3. Igabanuka rya valve (valve disc) rito mugihe ufungura cyangwa ufunze, igihe cyo gufungura cyangwa gufunze gito, kandi uburebure bwa valve buri rito.
4. Umupira w’umuryango ukoresha ubwoko bwo gufata (welding), kandi gufata byiza cyane.
II. Imipaka y’ikoranabuhanga
Imipaka isanzwe: 150LB ~ 600LB;
Uburebure busanzwe: 1" ~ 16";
Ubushyuhe busanzwe: 425℃ (WCB); -29 ~ 325 (CF8)
Ibintu byo gukoresha: amazi, umwuka, amavuta n’ibindi (WCB); ibintu bya nitric acid (CF8)
III. Inyandiko zifatika
1. Gukora no gukora: BS 1873;
2. Uburebure bw’imiterane: ASME B16.10;
3. Ubushyuhe bw’umuvuduko: ASME B16.34;
4. Kugenzura no gukora ibizamini: API 598.
