Iivalvu zebholazizinto ezibalulekileyo kwiinkqubo zolawulo lolwelo, zibonelela ngolawulo oluthembekileyo lokuvala kunye nokuhamba kwamanzi. Phakathi koyilo olwahlukeneyo,iivalvu zebhola ezifakwe imisontoZibalasele ngokulula kokufakwa kwazo kunye nokuguquguquka kwazo. Eli nqaku liyachazayintoni ivalvu yebhola, yayoukuhlelwa, izicelokunyeiindlela zemarike, kugxilwe kwiimodeli ezidumileyo ezifanaIvalvu yebhola yeziqwenga ezibini, Ivalvu yebhola yobhedu ye-intshi ezi-2kunyeIvalvu yebhola ye-2in.
Yintoni iValve yeBhola
Ivalvu yebhola isebenzisa ibhola ejikelezayo engenanto, enebhobo ukulawula ukuhamba kolwelo. Xa ibhobo yebhola ihambelana nombhobho, ulwelo luhamba ngokukhululekileyo; ukujika kweedigri ezingama-90 kuvala ukuhamba ngokupheleleyo. Iivalvu zebhola ezinemisonto zinemisonto edibanisa izikrufu (i-NPT okanye i-BSP threads), nto leyo eyenza ukuba zilungele iinkqubo zoxinzelelo oluphantsi ukuya koluphakathi kwimibhobho, kwi-HVAC, nakwiindawo zoshishino.
Izinto eziphambili ziquka:
- Ibhola: Yenziwe ngentsimbi eshayinayo, Intsimbi yekhabhoni (A105N, WCB), ithusi, okanye iPVC.
- Izihlalo: I-PTFE okanye irabha yokutywina.
- Isiqu: Uqhagamshela isibambo nebhola.
- Umzimba: Idla ngokwenziwa ngethusi, intsimbi engatyiwayo, okanye intsimbi eqinisiweyo.
