Umkhiqizo usetshenziselwa uhlelo lokuphakelwa kwamanzi lwamandla enuzi iyunithi ye-AP1000. Ngesikhathi sokusebenza kwayo, i-valve yesango kufanele ivuleke ngokugcwele noma ivaleke ngokuphelele esikhundleni sokusebenza njengokulawula ukugeleza nokucindezela.
- I-valve yamukela isakhiwo sokuzivala futhi imiphetho yayo yomibili ixhumeke ngokushiselwe.
- Indlela yokuvala iqukethe i-wedge yohlobo lwe-double-flashboard enesikhungo esilungisekayo, i-universal top kanye nebhodi yokubambela phansi. Iqondiswa yi-baffle eqondisayo emzimbeni we-valve, yenza ukunyakaza okuya phezulu naphansi.
- Nge-cobalt-based rigid alloy build-up welding, indawo yokuvala ifaka ukumelana nezinga lokushisa eliphezulu, ukumelana nokuhwamuka, ukumelana nokugqwala, ukulwa nokuklwebheka nempilo ende yesevisi; ukuphakama kwe-welding ye-valve disc nesihlalo ≥3mm.
- Nge-baffle eqondisayo, umzimba we-valve unikeza isiqondiso se-stroke esiphelele sokuvula nokuvala i-flashboard.
- Njengoba ibhekene nokwelashwa kwe-anti-corrosion kanye ne-nitrogenization, indawo engaphezulu ye-valve stem ifaka ukumelana nokugqwala okuhle, ukumelana nemihuzuko kanye nokuvalwa kwebhokisi lokugxusha okuthembekile.
- I-automatic wedge yohlobo lwe-double-flashboard isakhiwo esinesikhungo esilungisekayo sinezici ezilandelayo: isikhungo esiphezulu esiqinile kanye ne-cushion block (ukuxhumana okuyisiyingi) kungalungisa i-angle ehambisanayo phakathi kwe-flashboard nesihlalo se-valve ngokuzenzakalelayo ukuze zenze izindawo zabo zokuvala zibambelele ngokuqinile futhi ziqinisekise ukuvala okuqinile; iqembu lama-gaskets alungisayo lifakwe phakathi kwesikhungo esiphezulu kanye ne-flashboard ukulungisa ububanzi be-flashboard futhi unxephezele ukuhuzuka ngemva kokusebenza nokulungiswa kwe-flashboard. I-Elastic groove isethwe phakathi kwama-flashboards kwesokunxele nakwesokudla ukuze kuvinjelwe ukunamathela phakathi nokuvalwa kwamavalvu. I-flashboard yesakhiwo inokushintshwa okuhle kanye nobunzima obukhulu bokwenza, futhi izindleko zayo ezijwayelekile ziphakeme kune-parallel dual-flashboard kanye nezakhiwo ze-flashboard elastic.
- I-valve yamukela uhlobo lwesakhiwo sesihlalo se-welding-on valve. Ukutholwa kwempushana kazibuthe kwenzelwa ukushiselwa kwe-fillet ukuze kuqinisekiswe ikhwalithi ehlangene yokushisela ihambisana nezidingo ezijwayelekile.
- Uxhumano lwe-T-grooved kwamukelwa isiqu se-valve kanye ne-flashboard ye-automatic wedge dual-flashboard gate valvu enesikhungo esilungisekayo. Ibhodi elibamba phansi libekwe ku-T-groove ye-flashboard ukuze kukhawulwe ukuvuleka kwama-flashboards kwesokunxele nakwesokudla ngemva kokuvuleka kwe-valve nokuvimbela ukuwa kwe-flashboard. Inhloko yesiqu se-valve iyindilinga. Ngesikhathi sokuvalwa kwe-valve, amandla agxilile asetshenziswa yisiqu se-valve ebhodini elibamba phansi ukwenza amandla okuvala abe ngaphezulu ngisho naphakathi nokuvalwa kwe-flashboard nokuqinisekisa ngisho nokucindezeleka kwe-flashboard kanye nezindawo zokuvala izihlalo zama-valve kanye nokuvala kangcono.
- Nge-pendant collet njengengxenye eyinhloko yokucindezeleka, ingxenye yokuzivala ngokwayo ithatha ingxenye engumgunyathi futhi ukubumbana kwayo kwezicubu kuphakeme kunephaneli. Ngaleso sikhathi, yamukela ukutholwa kwe-ultrasonic okudidiyelwe kanye nezinqubo zokutholwa kwempushana kazibuthe ukuze kuqinisekiswe ikhwalithi yengxenye ehlanganisiwe ihambisana nezidingo ezijwayelekile.
