Iivalvu zebholazizinto ezibalulekileyo kwiinkqubo zokulawula ulwelo, ezibonelela ngokuvalwa okuthembekileyo kunye nolawulo lokuhamba. Phakathi koyilo olwahlukeneyo,iivalvu zebhola ezinemisontozivelele ukufakela kwazo lula kunye nokuguquguquka. Eli nqaku liyacacisayintoni ivalve yebhola, yayoUkuhlelwa, izicelo, kwayeiindlela zemarike, ngokugxila kwiimodeli ezidumileyo njengeIziqwenga ezi-2 zevalve yebhola, 2 intshi yevalve yebhola yobhedu, kwaye2in ivelufa yebhola.
Yintoni iValve yeBhola
Ivalve yebhola isebenzisa umngxuma, ibhola ejikelezayo enebhore ukulawula ukuhamba kwamanzi. Xa umbhobho webhola uhambelana nombhobho, ulwelo luhamba ngokukhululekileyo; i-90-degree turn block blocks ukuhamba ngokupheleleyo. Iivalvu zebhola ezinemisonto zibandakanya uqhagamshelo lwe-screw-end (i-NPT okanye i-BSP imisonto), ezenza zilungele iinkqubo zoxinzelelo olusezantsi ukuya kwephakathi kwimibhobho yamanzi, i-HVAC, kunye nezicwangciso zemizi-mveliso.
Amacandelo aphambili abandakanya:
- Ibhola: Yenziwe ngentsimbi eshayinayo, intsimbi yeCarbon (I-A105N, WCB), ubhedu, okanye iPVC.
- Izihlalo: PTFE okanye irabha yokutywinwa.
- Isiqu: Uqhagamshela isiphatho kwibhola.
- Umzimba: Idla ngokwenziwa ngobhedu, intsimbi engatyiwayo, okanye ngentsimbi ekhutshiweyo.
