Indawo yokuvula kunye nokuvala (ingqukuva) iqhutywa sisikhondo sevalve kwaye ijikeleza i-axis yesiqu sevalve.Isetyenziselwa ikakhulu ukunqumla okanye ukudibanisa okuphakathi kumbhobho, kwaye ingasetyenziselwa ukulungiswa kwamanzi kunye nokulawula.Olu hlobo lwevalve kufuneka lufakwe ngokubanzi ngokuthe tye kumbhobho.
Iimpawu zeplastikiivalve yebhola ebambeneyo:
(1) Uxinzelelo oluphezulu lokusebenza: uxinzelelo olusebenzayo lwezinto ezahlukeneyo lunokufikelela kwi-1.0Mpa kwiqondo lokushisa.
(2) Ubushushu bokusebenza olubanzi: Ubushushu bokusebenza bePVDF yi -20℃~+120℃;Ubushushu bokusebenza kwe-RPP yi -20℃~+95℃;Ubushushu bokusebenza be-UPVC yi -50℃~+95℃.
(3) Ukumelana nempembelelo elungileyo: i-RPP, i-UPVC, i-PVDF, i-CPVC inamandla amakhulu omatshini kunye nokuchasana kwempembelelo.
(4) Ukuchasana nokuhamba kolwelo oluphantsi: udonga lwangaphakathi olugudileyo lwemveliso, i-coefficient encinci ye-friction, kunye nokusebenza okuphezulu kokuhambisa.
(5) Iimpawu zeekhemikhali ezigqwesileyo: Le mveliso ayinayo ityhefu, ayinavumba, i-asidi kunye ne-alkali ukumelana, i-corrosion resistant, kwaye inoluhlu olubanzi lwezicelo.I-PPR isetyenziselwa ikakhulu ukutya, iziselo, amanzi etephu,
Amanzi acocekileyo kunye neminye imibhobho engamanzi kunye nezixhobo ezineemfuno zococeko nazo zinokusetyenziselwa imibhobho engamanzi kunye nezixhobo ezinokudleka okuphantsi;
I-RPP, i-UPVC, i-PVDF, i-CPVC isetyenziselwa ukujikeleza kolwelo (igesi) kunye ne-acids ezonakalisayo ezomeleleyo, ii-alkali ezinamandla kunye ne-acids exutywe.
(6) Ufakelo olufanelekileyo kunye nokungangeni komoya okulungileyo: le mveliso ilula ngobunzima, idityaniswe okanye idityanisiwe, izifakelo zombhobho ezipheleleyo, ulwakhiwo olulula, ukungangeni komoya kakuhle, kunye noxinzelelo lwabasebenzi oluphantsi.
Iimpawu eziphambili zevalve yebhola yeplastiki yinkqubo yayo edibeneyo, ukutywinwa okuthembekileyo, isakhiwo esilula, kunye nokugcinwa okufanelekileyo.Umphezulu wokutywina kunye nomphezulu we-spherical uhlala uvaliwe, akukho lula ukukhukuliseka ngokuphakathi, kwaye kulula ukuyisebenzisa kunye nokugcina.Ilungele amanzi, izinyibilikisi, iiasidi kunye negesi yendalo.Isixhobo esisebenzayo sikwafanelekile kuphakathi kunye neemeko zokusebenza ezinzima, ezifana neoksijini, i-hydrogen peroxide, i-methane kunye ne-ethylene, njl., ezisetyenziswa ngokubanzi kumashishini ahlukeneyo.Umzimba wevalve yebhola unokudityaniswa okanye udityaniswe.
