Umsebenzi weumbhobho wokucima umlilo ongaphantsi komhlaba
Phakathi kwezixhobo zangaphandle zokubonelela ngamanzi omlilo ophantsi komhlaba, i-hydrant fire hydrant yenye yazo.Isetyenziselwa ikakhulu ukubonelela ngamanzi kwiinjini zomlilo okanye izixhobo ezidityaniswe ngokuthe ngqo kunye nemibhobho yamanzi kunye nemipu yamanzi kunye nokucima umlilo.Kuyimfuneko ekhethekileyo yokumisela ukunikezelwa kwamanzi omlilo wangaphandle.Ifakwe phantsi komhlaba, ayiyi kuchaphazela ukubonakala kunye nokuhamba kwesixeko.Yenziwe ngeivalveumzimba, ingqiniba, ivalve yokukhupha amanzi kunye nesiqu sevalvu.Ikwasisixhobo esiyimfuneko sokucima umlilo ezixekweni, kwizikhululo zamandla, kwiindawo zokugcina iimpahla nakwezinye iindawo.Ifuneka ngakumbi kwiindawo zasezidolophini nakwiindawo ezinemilambo embalwa.Ineempawu zesakhiwo esifanelekileyo, ukusebenza okuthembekileyo kunye nokusetyenziswa okufanelekileyo.Xa usebenzisa i-hydrants yomlilo ephantsi komhlaba, kuyimfuneko ukubeka iimpawu ezicacileyo.Imibhobho yokucima umlilo engaphantsi komhlaba isetyenziswa kakhulu kwiindawo ezibandayo kuba akukho lula ukuba yonakaliswe kukukhenkceza.
Izinto ezilungileyo zombhobho womlilo ongaphantsi komhlaba
Inobufihla obuqinileyo, ayiyi kuchaphazela ubuhle besixeko, inezinga eliphantsi lomonakalo, kwaye inokukhenkceka kwiindawo ezibandayo.Ngokubhekiselele kumasebe okusetyenziswa kunye nokulawula, akulula ukufumana kunye nokulungiswa, kwaye kulula ukungcwatywa, ukuhlala kwaye ucinezele ukupaka izithuthi zokwakha.Uninzi lwemibhobho yokucima umlilo ephantsi komhlaba kufuneka ikhuselwe kwigumbi lomthombo, kwaye kuya kutyalwa imali eninzi.Ekucwangcisweni komnatha wombhobho ongaphantsi komhlaba, ezininzi ezingaziwa zixakeke, kwaye ukucwangciswa kwakhona kunzima kakhulu.
Umda wokuphuma weisixhobo sokucima umliloayiyi kuba ngaphantsi kwe-φ 100mm, ngenxa yokwanda kwezakhiwo zasezidolophini kunye nokuxinana kwabemi, ubunzima bokucima umlilo buyanda.Ukuze kuqinisekiswe imfuno yamanzi yokucima umlilo wokucima uxinzelelo lwamanzi, ubuncinane qinisekisa ukuba i-diameter yokuphuma ye-hydrant yomlilo ayikho ngaphantsi kwe-φ 100mm.
Indawo yokuvula nokuvalwa kombhobho wokucima umlilo ongaphantsi komhlaba uya kufana, kwaye uya kuvalwa ngokwewotshi kwaye uvule ngokunxamnye newotshi.Intsimbi engenastainless ikhethwa njenge-screw rod, kwaye irabha ye-NBR isetyenziswa njengekomityi yokutywina.I-anti-corrosion kwi-cavity kukuhlangabezana nezibonakaliso zococeko zamanzi okusela, kunye neemfuno ezifanayo njenge-valve.
