Valve Kuiswa Mamiriro ezvinhu chikamu chakakosha chekuisa ruzha rwuviri. Ndezvipi zvinhu zvinoisa chisimbiso? Isu tinoziva kuti vhezheni inosimbisa mhete dzinogovaniswa mumapoka maviri: simbi uye isiri yesimbi. Izvi zvinotevera chiratidzo chebudiriro kumamiriro ekushandiswa zvemari dzakasiyana-siyana dzekuisa mari, pamwe chete neanowanzo shandiswa mhando dzevhu.
1. Synthetic Rubber
Zvivakwa zvakazara zveSynthetic rabha senge kupokana nemafuta, kupisa kurwisa uye kurwisa kwekora kuri nani pane izvo zvezvisikwa zvakasikwa. Kazhinji, tembiricha yekushandisa yeiyo synthetic rabha iri T≤150 ℃, uye tembiricha yemasikirwo marara iT≤60 ℃ .Rubber inoshandiswa kusimbisa mavharuvhu,Rabha yakagara Gate Valve, diaphrag mugavhu,rubber yakagara butterfly vheji, rubber akagara swing tarisa vheji (Tarisa mavharuvhu), pinch mavhavha nemamwe matsime ane zita rekudzvinyirira pn≤1mpa.
