Umsebenzi weumshini wokucisha umlilo ongaphansi komhlaba
Phakathi kwezindawo ezingaphandle zokuhlinzeka ngamanzi omlilo ongaphansi komhlaba, i-hydrant fire hydrant ingenye yazo. Isetshenziselwa ikakhulukazi ukuhlinzeka ngamanzi ezinjini zomlilo noma amadivaysi axhunywe ngokuqondile namapayipi amanzi nezibhamu zamanzi kanye nomlilo ocishayo. Kuyisilungiselelo esikhethekile esidingekayo sokuhlinzekwa kwamanzi omlilo ongaphandle. Kufakwe ngaphansi komhlaba, ngeke kuthinte ukubukeka nokuhamba kwedolobha. Yakhiwai-valveumzimba, indololwane, i-valve yokukhipha amanzi kanye nesiqu se-valve. Kuphinde kube yithuluzi lokucisha umlilo elibalulekile emadolobheni, eziteshini zikagesi, ezindaweni zokugcina izimpahla nakwezinye izindawo. Idingeka ikakhulukazi ezindaweni zasemadolobheni nasezindaweni ezinemifula embalwa. Inezici zesakhiwo esinengqondo, ukusebenza okuthembekile nokusetshenziswa okulula. Uma usebenzisa ama-hydrants omlilo ongaphansi komhlaba, kuyadingeka ukubeka izimpawu ezicacile. Amapayipi okucisha umlilo angaphansi komhlaba asetshenziswa kakhulu ezindaweni ezibandayo ngoba akulula ukuthi wonakaliswe wukuqandisa.
Izinzuzo ze-underground fire hydrant
Inokucasha okuqinile, ngeke iphazamise ubuhle bedolobha, inezinga eliphansi lomonakalo, futhi ingaba yiqhwa ezindaweni ezibandayo. Ngokuqondene neminyango yokusetshenziswa nokuphatha, akulula ukuthola nokulungisa, futhi kulula ukungcwatshwa, ukuhlalwa nokucindezelwa ukupaka izimoto zokwakha. Amapayipi amaningi okucisha umlilo angaphansi komhlaba adinga ukuvikelwa yigumbi lomthombo, futhi kuzotshalwa imali eningi. Ekuhleleni inethiwekhi yamapayipi angaphansi komhlaba, izinto eziningi ezingaziwa zimatasa, futhi ukuhlela nakho kunzima kakhulu.
Ububanzi bokuphuma kweumshini wokucisha umliloakumele kube ngaphansi kuka-φ 100mm, ngenxa yokwanda kwezakhiwo zasemadolobheni kanye nokuminyana kwabantu, ubunzima bokucisha umlilo buyanda. Ukuze uqinisekise imfuneko yamanzi yokucindezela kwamanzi okucima umlilo, okungenani qinisekisa ukuthi ububanzi bokukhipha ipayipi lomlilo abukho ngaphansi kuka-φ 100mm.
Indlela yokuvula neyokuvala yomshini wokucisha umlilo ongaphansi komhlaba izofana, futhi izovalwa ngokwewashi futhi ivulwe ngokuphambene newashi. Insimbi engagqwali ikhethwa njenge-screw rod, futhi irabha ye-NBR isetshenziswa njengenkomishi yokuvala. I-anti-corrosion emgodini ukuhlangabezana nezinkomba zenhlanzeko yamanzi okuphuza, ngisho nezidingo ezifanayo njenge-valve.
