| Pin yopangira | SS416,SS420,SS431,17-4PH |
Mafotokozedwe Ampando:
| Zakuthupi | Kutentha | Gwiritsani Ntchito Kufotokozera |
| NBR | -23 ℃ ~ 82 ℃ | Buna-NBR: (Nitrile Butadiene Rubber) ili ndi mphamvu zolimba komanso zotsutsana ndi abrasion. Imalimbananso ndi zinthu za hydrocarbon. Ndizinthu zabwino zothandizira anthu kuti zigwiritsidwe ntchito m'madzi, vacuum, asidi, mchere, alkaline, mafuta, mafuta, mafuta, mafuta a hydraulic ndi ethylene glycol. Buna-N sangagwiritse ntchito acetone, ketones ndi nitrated kapena chlorinated hydrocarbons. |
| Nthawi yowombera-23 ℃ ~ 120 ℃ | ||
| Chithunzi cha EPDM | -20 ℃ ~ 130 ℃ | General EPDM rabara: ndi mphira wopangira wabwino kwambiri womwe umagwiritsidwa ntchito m'madzi otentha, zakumwa, zopangira mkaka ndi zomwe zimakhala ndi ketoni, mowa, nitric ether esters ndi glycerol. Koma EPDM sangathe ntchito hydrocarbon zochokera mafuta, mchere kapena zosungunulira. |
| Nthawi yowombera-30 ℃ ~ 150 ℃ | ||
| Viton | -10 ℃ ~ 180 ℃ | Viton ndi fluorinated hydrocarbon elastomer yolimbana kwambiri ndi mafuta ambiri a hydrocarbon ndi mpweya ndi zinthu zina zochokera ku petroleum. Viton sangagwiritse ntchito ntchito ya nthunzi, madzi otentha opitilira 82 ℃ kapena ma alkaline okhazikika. |
| PTFE | -5 ℃ ~ 110 ℃ | PTFE ili ndi kukhazikika kwamphamvu kwamankhwala komanso pamwamba sikudzakhala kokakamira.Pa nthawi yomweyo, ili ndi katundu wabwino wamafuta komanso kukana kukalamba. Ndi chinthu chabwino chogwiritsidwa ntchito mu zidulo, alkalis, oxidant ndi corrodents zina. |
| (Inner liner EDPM) | ||
| PTFE | -5 ℃ ~ 90 ℃ | |
| (NBR) |
Ntchito:lever, gearbox, actuator yamagetsi, pneumatic actuator.
Makhalidwe:
1.Stem mutu kapangidwe ka Double "D" kapena Square mtanda: Yosavuta kulumikizana ndi ma actuators osiyanasiyana, perekani torque yambiri;
2.Two piece stem square driver: Palibe-malo kulumikizana kumagwira ntchito pazovuta zilizonse;
3.Thupi lopanda chimango: Mpando ukhoza kulekanitsa thupi ndi sing'anga yamadzimadzi ndendende, komanso yabwino ndi chitoliro.
