Pneumatic British Fluorine Lined/EPDM Lined Diaphragm Valve Introduction
ʻO ka pneumatic piston diaphragm regulating valve i haku ʻia me ka valve diaphragm a me ka mea hana pneumatic.Hoʻohana ʻo ia i ka ea i hoʻopaʻa ʻia e like me ka mana e hoʻoponopono i ke kahe o ka wai i loko o ka pipeline kaʻina.
Ma muli o ke ʻano o ke kino o ka valve me ka pale corrosion-resistant a me ka corrosion-resistant diaphragm, ʻaʻohe hale pahu pahu, ʻo ka throttle element he diaphragm elastic, a maʻemaʻe ke kahe kahe o ke kino valve, no laila ua loaʻa ka valve diaphragm film pneumatic. liʻiliʻi maikaʻi ʻole, kahe nui, Me nā pono o ka leakage, ʻoluʻolu, hilinaʻi, ke ahi a me ka pale pahū, ua hoʻohana nui ʻia i ka hoʻoponopono kahe ʻana o nā waikawa ikaika, alkalis ikaika, corrosion ikaika, viscosity kiʻekiʻe, nā kīʻaha, nā fibers, a me nā mea ʻawaʻawa. mea hoʻohaumia ʻole i nā ʻōnaehana ʻoihana ʻenehana.
ʻO ka pani ʻana a me ka wehe ʻana o ka valve diaphragm e ʻike ʻia e ke kaomi ʻana mai ka pipeline e hana ana i ka diaphragm rubber reinforced.Ke komo ka mea kaomi i loko o ke keʻena hoʻomalu o ka valve, kaomi ka diaphragm i lalo a pani i ke ala o ka valve.Ke hoʻokuʻu ʻia ke kaomi i loko o ke keʻena hoʻomalu i ka lewa a i ʻole ka pipeline o lalo, piʻi ka diaphragm a wehe ʻia ke ala o ka valve.ʻAʻohe o ka valve stem, gasket, orienting noho, a me nā mea ʻē aʻe, a ʻo ka ʻāpana neʻe wale i ke kahawai ʻo ka diaphragm, no laila ʻaʻohe corrosion a me ka laka ʻana, a ʻoi aku ka kiʻekiʻe.Hiki ke hoʻohana ʻia nā ʻano hana like ʻole a me nā ʻano hoʻomalu i nā ʻano pono hoʻomalu wai.
