Ivalve yeBhola edadayo yeZiqwenga ezi-3
Yintoni ivalvu yebhola edadayo enamaqhekeza amathathu?
IIvalve yeBhola edadayo yeZiqwenga ezi-3 inezihlanganisi ezimbini zomzimba nto leyo ethetha ukuba umzimba wenziwe ngeziqwenga ezintathu, nto leyo ebangela igama elithi "iziqwenga ezintathu." Olu lwakhiwo lomzimba oluneziqwenga ezintathu luvumela ukuba kufakwe ibhola enkulu ngexesha lokwenziwa, nto leyo eyenza ukuba ibe yivalvu yebhola egcweleyo (i-Full port).
I-NortechIziqwenga ezi-3Ivalvu yebhola edadayoyimveliso entsha eyenziwe ngokuguqula ivalvu eqhelekileyo kunye nokwamkelwa komgangatho wamazwe ngamazwe ohlaziyiweyo.
Iimpawu eziphambili zevalvu yebhola edadayo enamaqhekeza amathathu
Iimpawu eziphambili zeIivalvu zebhola ezidadayo eziziinxalenye ezintathu
- Umzimba ogcweleyo, uyayiphepha into yokuvaleka kwaye uqinisekisa ukuhamba kakuhle xa uphatha izinto ezimdaka neziqinileyo.
- Ifumaneka ivavanywe ngomlilo kwi-API-607 Rev. 5
- Uyilo luhambelana ne-ASME B16.34 / BS5351.
- I-GFT thrust-washer ithintela ukurhawuzelelwa kwaye ithintela ukuguguleka.
- Izinto ezihambelana nemigaqo ye-NACE.
- Isiqu esithintela ukuqhuma.
- Ukupakisha ukukhutshwa komoya okuphantsi.
- Isiqu esipheleleyo esikhokelwayo, esinokuthwala i-gland;
- Iinwele ezintathu zokutywinwa kwesiqu kwangaphambili;
- Ukujikeleza kwesiqu ngokuzimeleyo (ukujikeleza ngaphandle kwe-gland nut);
- Isiqu esandisiweyo siyafumaneka;
- Uyilo lwebhokisi yokuzalisa epakishwe kabini;
- Uyilo oluchasene nokungashukumi;
- Inqanaba lokuvuza iKlasi VI
- Iflange yokufaka i-Actuator DIN/ISO 5211
