I-API Standard B367 Gr.C-2 Worm Gear Operated Metal Seated Ball Valve

Ibhola le-valve yebhola elintantayo liyantanta, futhi ngaphansi kwengcindezi ye-medium, ibhola lingakhiqiza ukugudluka okuthile futhi licindezele ngokuqinile endaweni yokuvala yokuphela kwe-outlet, iqinisekise ukuvala ukuphela kokuphumayo. I-valve yebhola elintantayo inesakhiwo esilula nokusebenza okuhle kokuvala, kodwa ibhola lithwala wonke umthwalo we-medium yokusebenza futhi lidluliselwa eringini yokuvala indawo. Ngakho-ke, kuyadingeka ukucabangela ukuthi impahla yendandatho yokuvala ingamelana nomthwalo wokusebenza we-ball medium. Uma ingaphansi komthelela wengcindezi ephezulu, ibhola lingase liphambuke. Lesi sakhiwo ngokuvamile sisetshenziselwa ama-valve ebhola aphakathi nendawo naphansi.

Izici eziyinhloko ze-valve yebhola yisakhiwo sayo esihlangene, ukubekwa uphawu okuthembekile, isakhiwo esilula, ukugcinwa okulula, futhi indawo yokubeka uphawu kanye ne-spherical surface kuvame ukuba sesimweni esivaliwe, esingaqedwa kalula yi-medium. Kulula ukuyisebenzisa nokuyinakekela, ilungele imidiya evamile yokusebenza njengamanzi, izincibilikisi, ama-asidi, negesi yemvelo, futhi ifanelekela izimo zokusebenza ezinzima ezifana ne-oxygen, i-hydrogen peroxide, i-methane, ne-ethylene. Isetshenziswe kabanzi ezimbonini ezihlukahlukene. Umzimba we-valve we-valve yebhola ungaba yinto ebalulekile noma i-modular.

- Usayizi kusuka ku-2 "kuya ku-8" ( DN50mm kuya ku-DN200mm).
- Izilinganiso zokucindezela ukusuka ku-Class 150LB kuya ku-600LB (PN10 kuya ku-PN100).

- Imodi yokushayela ingaba imanuwali, kagesi, i-pneumatic, noma ifakwe ipulatifomu ye-ISO.
- Insimbi yokusakaza noma impahla yensimbi eyenziwe ngomgunyathi

1. Ukumelana nokugeleza kwe-valve yebhola kuncane. Lapho kuvulwa i-valve yebhola yobubanzi obugcwele, ishaneli yebhola, ishaneli yomzimba we-valve, nobubanzi bepayipi elixhumayo kuyalingana futhi kwenza ububanzi, futhi okuphakathi kungageleza cishe ngaphandle kokulahlekelwa.

2. I-valve yebhola ingavalwa ngokugcwele futhi ivuleke ngokugcwele ngokuzungeza i-90 °, ngokuvula nokuvala ngokushesha. Uma kuqhathaniswa namavalvu esango naweglobhu anezincazelo ezifanayo, amavalvu ebhola anevolumu encane nesisindo esilula, okwenza kube lula ukuwafaka kumapayipi.

3. Isihlalo se-valve esithuthukisiwe: Isihlalo se-valve siklanywe ngokusekelwe eminyakeni yokuhlangenwe nakho kokukhiqiza ama-valve ebhola, ukuqinisekisa ukuvaleka kwe-valve, i-coefficient ephansi ye-friction, i-torque encane yokusebenza, izinto zezihlalo zama-valve amaningi, kanye nohlu olubanzi lwezinhlelo zokusebenza.

4. Isibambo se-switch samahhala esinephutha: kusetshenziswa isiqu se-valve yekhanda eliyisicaba, ukuxhumana nesibambo ngeke kumiswe kabi, kuqinisekisa ukuthi isimo sokushintsha esikhonjiswe yisibambo sihambisana naleso se-valve.

5. Idivayisi yokukhiya: Ukuvimbela ukungasebenzi kahle kwevalvu yokuvula nokuvala, kunezimbobo zokukhiya ezindaweni ezivuleke ngokugcwele nezivaleke ngokugcwele zevalvu ukuze kuqinisekiswe ukuthi isendaweni efanele.

6. Isiqu se-valve esimelene nokundizayo: Isiqu se-valve sibekwe phansi ukuze sinqande ukucindezela ekundizeleni ngaphandle. Ngesikhathi esifanayo, ingakha ukuxhumana kwensimbi nomzimba we-valve ngemva komlilo, iqinisekise ukuthi isiqu se-valve sivaliwe.
