Valve ndiro izwi rakajairwa rezvikamu zvekudzora zvinotsausa, kucheka uye kugadzirisa mvura
Nhoroondo yeindasitiri yevharuvhu
Tichitarisa kumashure kwekwakabva vharuvhu, inofanira kurondwa kudzokera kuchinhu chemapuranga mumatongo eEjipita ekare aifungidzirwa kuva vharuvhu muna 1000 AD.Munguva yeRoma yekare, kwaitova nemidziyo yepombi mudzimba dzevakuru uye mavharuvhu ebhuronzi ekutengesa kunze.
Gare gare, teknolojia yevhavha yakagadziridzwa zvakare.Nekuvandudzwa kwehunyanzvi hwekugadzira mavharuvhu esimbi yakakandwa, nzira nyowani dzekukanda dzakagamuchirwa uye zvinhu zvakagadziridzwa.Ivhavha yesimbi inotora michina yekushanda ine simba, uye iko kurongeka kwakagadziridzwa zvakare.
Kuti utsungirire kushomeka kwemvura yepombi dzekuvaka, mirau yeruzha ine chekuita nezvivakwa zvechigadzirwa, uye kukwidziridzwa kwekuchengetedzwa kwegasi, mavharuvhu anosanganisira anti-corrosion mavharuvhu epombi dzekupa mvura, mavharuvhu akadzika-ruzha ekudzikisa ruzha, socket tepi, uye. fusing.Shanduko yesirika gasi plugs.
Iye zvino tavambayakakosha mavharuvhu michinauyevalve processing machineanogona kuita izvi.Mushure mekuvandudzwa kwakati wandei, ikozvino yekucheka chishandiso kugona kusvika 10mm.Inoshanda, yakanakira, yakagadzikana uye yakavimbika.Yakatsaurirwa kugadzirisa simbi yakagadzirwa, simbi yakakandwa, mavharuvhu egedhi, mavharuvhu epasi, Butterfly mavharuvhu, magokora, nezvimwe.
