Zida zitatu zosindikizira zomwe zimagwiritsidwa ntchito popanga ma valve a solenoid

1. NBR mphira wa nitrile
Valavu ya solenoid imapangidwa ndi emulsion polymerization ya butadiene ndi acrylonitrile. Nitrile mphira makamaka opangidwa ndi otsika kutentha emulsion polymerization. Ili ndi kukana kwambiri kwamafuta, kukana kwambiri kuvala, kukana kutentha kwabwino, komanso kumamatira mwamphamvu. Zoipa zake ndizosakanizidwa bwino ndi kutentha kwapansi, kukana kwa ozoni, kutsika kwa magetsi, komanso kutsika pang'ono. Cholinga chachikulu cha valavu ya solenoid: mphira wa solenoid nitrile amagwiritsidwa ntchito kwambiri popanga zinthu zosagwira mafuta. Ma valve a solenoid monga mapaipi osamva mafuta, matepi, ma diaphragms a rabara ndi matumba akuluakulu amafuta amagwiritsidwa ntchito popanga zinthu zosiyanasiyana zosamva mafuta, monga mphete za O, zosindikizira zamafuta, ndi zikopa. Ma mbale, ma diaphragms, mavavu, mavuvu, ndi zina zotero amagwiritsidwanso ntchito kupanga mapepala a rabala ndi ziwalo zosagwira ntchito.
2. EPDM EPDM (Ethylene-Propylene-Diene Monomer) solenoid valve Gawo lalikulu la EPDM ndikulimbana kwambiri ndi makutidwe ndi okosijeni, ozoni ndi dzimbiri. Popeza EPDM ndi ya banja la polyolefin, ili ndi katundu wabwino kwambiri. Mwa ma rubbers onse, EPDM ili ndi mphamvu yokoka yotsika kwambiri. Valavu ya solenoid imatha kuyamwa mafuta ochulukirapo osakhudzanso mawonekedwe ake. Chifukwa chake, mankhwala a mphira wotsika mtengo amatha kupangidwa. Mapangidwe ndi mawonekedwe a Solenoid valve mamolekyulu ndi mawonekedwe: EPDM ndi terpolymer ya ethylene, propylene ndi diene yopanda cholumikizira. Diolefins ali ndi kapangidwe kapadera. Chimodzi mwazinthu ziwiri zokha za valavu ya solenoid ndiomwe zimatha kupopedwa, ndipo maunyolo awiri osagwiritsidwa ntchito amagwiritsidwa ntchito ngati maulalo. Wina wosakwaniritsidwa sadzakhala unyolo waukulu wa polima, koma amangokhala unyolo wammbali. Chingwe chachikulu cha polima cha EPDM chimakhala chokwanira. Mbali imeneyi ya solenoid valve imapangitsa EPDM kugonjetsedwa ndi kutentha, kuwala, mpweya, makamaka ozoni. EPDM kwenikweni siyopanda polar, imatsutsana ndi mayankho am'madzi ndi mankhwala, imakhala ndi kuyamwa kotsika kwamadzi, ndipo imakhala ndi zotsekera zabwino. Makhalidwe a valve a Solenoid: â 'kachulukidwe kotsika ndikudzazidwa kwambiri; â‘¡ kukana kukalamba; â ‘resistance kukana dzimbiri; â ‘£ kukana nthunzi kwa madzi; ⑤ kutentha kwambiri kwamadzi; â ‘performance magwiridwe amagetsi; ⑦ kukhazikika; ⑧ kumamatira.
3. VITON Fluorine Rubber (FKM)
Rabara yokhala ndi fluorine mu molekyulu ya valavu ya solenoid ili ndi mitundu yosiyanasiyana malinga ndi zomwe zili ndi fluorine, ndiko kuti, mawonekedwe a monomer; mphira wa fluorine wa mndandanda wa solenoid valve hexafluoride ndi wabwino kuposa mphira wa silicone pa kutentha kwakukulu, kukana mankhwala, ndi valavu ya solenoid imagonjetsedwa ndi mafuta ambiri Ndipo zosungunulira (kupatula ketoni ndi esters), kukana kwa nyengo, kukana kwa ozoni ndikwabwino, koma kuzizira. kukana ndi osauka; ma valve solenoid nthawi zambiri amagwiritsidwa ntchito kwambiri pamagalimoto, njinga zamoto, B ndi zinthu zina, ndi zisindikizo muzomera zamankhwala. Kutentha kwa ntchito ndi -20 ° C. ～260℃, mtundu wosagwirizana ndi kutentha ungagwiritsidwe ntchito pamene zofunikira zochepetsera kutentha zimagwiritsidwa ntchito, zomwe zingagwiritsidwe ntchito ku -40℃, koma mtengo ndi wapamwamba.
