Valve details! Hezvino zvese zvausingazive nezve Angle mavharuvhu
Kana iyo Angle valve ichidonha, uye ikaonekwa kuti musimboti weAngle valve wakatyoka, inogona chete kushandura Angle valve. Kana zvikaonekwa kuti nzvimbo yekuvuza yeAngle valve iri pachiratidziro, ingo sungazve bhandi rekuisa chisimbiso uye risimbise. Muhupenyu chaihwo, iyo yegonyo vharafu pamvura hita yakaputika pakangopera imba itsva yevamwe varidzi, izvo zvakaita kuti mapaipi adonhe uye akazara pasi, TV cabinet, wadhiropu, etc. Izvi zvinoitika, kazhinji nokuti kunaka kwe iyo Angle valve haina kukonzerwa ne. Naizvozvo, mukuita kwekushongedza kwemba, isu tinofanirwa kuterera kusarudzo yemhando yakanaka Angle vharafu usave penny akachenjera uye pound benzi.
