ʻO ka pahu diaphragmhe pahupaʻi pani e hoʻohana ana i ka diaphragm ma ke ʻano he wehe a pani ʻana e pani i ke kahawai kahe, ʻoki i ka wai, a hoʻokaʻawale i ka lua o loko o ke kino valve mai ka lua o loko o ka uhi valve.Hana ʻia ka diaphragm me ka ʻōpala, ka plastic a me nā mea elastika ʻē aʻe, pale i ka corrosion, a me nā mea hiki ʻole ke komo.Hana ʻia ke kino valve me ka plastic, ka fiber glass reinforced plastic, ceramic a i ʻole nā mea i hoʻopaʻa ʻia.ʻO ke ʻano maʻalahi, hoʻopaʻa maikaʻi a me ka hana anti-corrosion, a me ka haʻahaʻa haʻahaʻa o ka wai.Hoʻohana ʻia ia no ka media me ka haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa, ikaika corrosiveness a me ka mea i hoʻokuʻu ʻia.Wahi a ka hale, aia ke ʻano o ka hale, ke ʻano ʻoki ʻia, ke ʻano ʻīpuka a pēlā aku.Wahi a ke ʻano hoʻokele, ua māhele ʻia i ka manual, pneumatic a me ka uila.
ʻOkoʻa loa ke ʻano o ka valve diaphragm mai ka valve maʻamau.Heʻano hou ia o ka valve a me keʻano kūikawā o ka valve oki.ʻO kona wehe a pani ʻana he diaphragm i hana ʻia me nā mea palupalu.Hoʻokaʻawale ʻia ka lua o loko o ka uhi a me ka ʻāpana hoʻokele a hoʻohana nui ʻia i kēia manawa ma nā ʻano āpau.ʻO nā kiwi diaphragm maʻamau i hoʻohana ʻia i loko o nā pahu diaphragm i hoʻopaʻa ʻia i ka lāʻau, nā kiwi diaphragm i hoʻopaʻa ʻia i ka fluorine, nā kiwi diaphragm ʻole, a me nā kiwi diaphragm plastic.
Hoʻokomo ʻia ka valve diaphragm me ka diaphragm maʻalahi a i ʻole ka diaphragm i hui pū ʻia i loko o ke kino valve a me ka uhi valve, a ʻo kāna ʻāpana pani he mea hoʻopili i pili me ka diaphragm.Hiki ke ʻano weir-like ka noho valve, a i ʻole he pā paipu e hele ana ma ke kahawai kahe.ʻO ka pōmaikaʻi o ka valve diaphragm ʻo ia ka hoʻokaʻawale ʻana o kāna hana hana mai ke ala waena, ʻaʻole ia e hōʻoia i ka maʻemaʻe o ka mea hana, akā pale pū nō hoʻi i ka hiki ʻana o ka medium i ka pipeline mai ka hopena i nā ʻāpana hana o ka mīkini hana.Eia hou,ʻaʻohe pono e hoʻohana i kekahiʻano o ka sila kaʻawale ma ka pahu valve, keʻole ia e hoʻohanaʻia ma keʻano he wahi palekana i ka mālamaʻana i nā media pōʻino.I loko o ka valve diaphragm, no ka mea, pili wale ka mea hana me ka diaphragm a me ke kino valve, hiki iā ia ke hoʻohana i nā ʻano mea like ʻole, hiki i ka valve ke hoʻomalu pono i nā ʻano media hana, ʻoi aku ka maikaʻi no ka chemically corrosive a i hoʻokuʻu ʻia. particles medium.ʻO ka mahana hana o ka valve diaphragm e kaupalena ʻia e nā mea i hoʻohana ʻia i ka diaphragm a me ka uhi o ke kino valve, a ʻo kona pae wela hana ma kahi o -50 ~ 175 ℃.He ʻano maʻalahi ka pahu diaphragm, ʻekolu wale nō ʻāpana nui: ke kino valve, ka diaphragm a me ka hui poʻo valve.He mea maʻalahi ka valve e wehe koke a hoʻoponopono, a hiki ke hoʻopau ʻia ke pani o ka diaphragm ma ka pūnaewele a i ka manawa pōkole.
Ke kumu hana a me ka haku mele:
Ke hoʻohana nei ka valve diaphragm i ke kino lining-resistant a me ka corrosion-resistant diaphragm ma kahi o ka hui valve core, a hoʻohana ʻia ka neʻe ʻana o ka diaphragm no ka hoʻoponopono ʻana.ʻO ke kino valve o ka valve diaphragm i hana ʻia me ka hao hao, ke kila kila, a i ʻole ke kila kila, a hoʻopaʻa ʻia me nā ʻano mea ʻino ʻole a i ʻole nā mea ʻaʻahu ʻole, diaphragm material rubber a me polytetrafluoroethylene.ʻO ka lining diaphragm he kūpaʻa kūpaʻa ikaika a kūpono no ka hoʻoponopono ʻana i nā media corrosive ikaika e like me ka waikawa ikaika a me ka alkali ikaika.
ʻO ka valve diaphragm kahi hana maʻalahi, haʻahaʻa haʻahaʻa o ka wai, a ʻoi aku ka nui o ka kahe kahe ma mua o nā ʻano ʻano valve like ʻole;ʻaʻohe leakage a hiki ke hoʻohana ʻia no ka hoʻoponopono ʻana i ka viscosity kiʻekiʻe a me ka media particulate suspended.Hoʻokaʻawale ka diaphragm i ka waena mai ka lua o luna o ke kumu valve, no laila ʻaʻohe mea hoʻopili a ʻaʻohe leakage.Eia nō naʻe, ma muli o ka palena o ka diaphragm a me nā mea lining, ʻaʻole maikaʻi ka pale ʻana i ke kaomi a me ke kūpaʻa wela, a kūpono wale ia no ke kaomi nominal o 1.6MPa a ma lalo o 150 ° C.
ʻO ke ʻano kahe o ka valve diaphragm kokoke i ka ʻano wehe wikiwiki, ʻo ia ka linear ma mua o 60% o ka hahau ʻana, a ʻaʻole loli nui ka kahe kahe ma hope o 60%.Hiki ke hoʻolako pū ʻia nā valve diaphragm pneumatic me nā hōʻailona manaʻo, nā palena a me nā kūlana e hoʻokō i nā pono o ka mana otometi, ka hoʻokele polokalamu a i ʻole ka hoʻoponopono kahe.ʻO ka hōʻailona manaʻo o ka valve diaphragm pneumatic e hoʻohana i ka ʻenehana ʻike ʻike ʻole.Hoʻohana ka huahana i ka cylinder type propulsion cylinder ma kahi o ka piston cylinder, e hoʻopau ana i ka hemahema o ka maʻalahi o ka pōʻino i ke apo piston, e hoʻoulu ai i ka leakage a hiki ʻole ke pana i ka valve e wehe a pani.Ke hāʻule ke kumu ea, hiki ke hoʻohana ʻia ka huila lima e wehe a pani i ka pahu.
ʻO ke kumu hoʻopaʻa paʻa o ka valve diaphragm e hilinaʻi i ka neʻe ʻana i lalo o ka mīkini hana e kaomi i lalo i ka diaphragm a i ʻole ka hui diaphragm a me ke kahawai o ka weir-type lining valve body a i ʻole ke kino lining valve kino e hoʻokō i kahi sila. .Hoʻokō ʻia ke kaomi kikoʻī o ka sila e ke kaomi iho o ka lālā pani.No ka mea hiki ke hoʻopaʻa ʻia ke kino valve me nā mea palupalu like ʻole, e like me ka rubber a i ʻole polytetrafluoroethylene, etc.;hana ʻia ka diaphragm me nā mea palupalu, e like me ka rubber or synthetic rubber lined polytetrafluoroethylene, no laila hiki ke hoʻokō ʻia me ka ikaika sealing liʻiliʻi i hoʻopaʻa ʻia.
ʻEkolu wale nō mau mea nui o nā ʻūhā diaphragm: kino, diaphragm a me ka hui pāpale.Hoʻokaʻawale ka diaphragm i ka lua o loko o ke kino valve haʻahaʻa mai ka lua o loko o ka uhi o ka pahu kiʻekiʻe, i ʻole ka pahu valve, ka valve stem nut, valve clack, pneumatic control mechanism, electric control mechanism a me nā ʻāpana ʻē aʻe ma luna o ka diaphragm. e hui pū me ka mea ʻenehana, ʻaʻohe mea i hana ʻia.Mālama ka leaka o waho i ke ʻano hoʻopaʻa ʻana o ka pahu hoʻopiha.
Ma kahi e pili ai ka valve diaphragm
ʻO ka valve diaphragm kahi ʻano kūikawā o ka valve pani.ʻO kona wehe a pani ʻana he diaphragm i hana ʻia i nā mea palupalu, kahi e hoʻokaʻawale ai i ka lua o loko o ke kino valve mai ka lua o loko o ka uhi valve.
Ma muli o ka palena o ke kaʻina hana hoʻopili kino valve a me ke kaʻina hana diaphragm, ʻoi aku ka paʻakikī o ka lining kino valve nui a me ke kaʻina hana diaphragm nui.No laila, ʻaʻole kūpono ka pahu diaphragm no nā anawaena paipu nui, a hoʻohana mau ʻia no nā paipu ma lalo o DN200.Ma ke ala.
Ma muli o ka palena o nā mea diaphragm, kūpono ka valve diaphragm no ka haʻahaʻa haʻahaʻa a me nā manawa wela haʻahaʻa.ʻAʻole iʻoi aku ma mua o 180 ° C.Ma muli o ka hana anti-corrosion maikaʻi o ka valve diaphragm, hoʻohana maʻamau ia i nā mea media corrosive a me nā pipeline.No ka mea, ua kaupalena ʻia ka mahana hana o ka valve diaphragm e ka mea kūpono o ka mea hoʻopili kino diaphragm valve a me nā mea diaphragm.
Nā hiʻohiʻona:
(1) He liʻiliʻi ke kūpaʻa wai.
(2) Hiki ke hoʻohana ʻia no ka mea paʻa paʻa i hoʻopaʻa ʻia;no ka mea, pili wale ka mea waena i ke kino valve a me ka diaphragm, ʻaʻohe pono o ka pahu pahu, ʻaʻohe pilikia o ka leakage pahu pahu, a ʻaʻohe hiki ke ʻino i ke kumu valve.
(3) He kūpono no ka media corrosive, viscous, a slurry.
(4) ʻAʻole hiki ke hoʻohana ʻia i nā manawa kiʻekiʻe.
Hoʻokomo a mālama:
①Ma mua o ka hoʻokomo ʻana i ka valve diaphragm, e nānā pono inā pili nā kūlana hana o ka pipeline me ke ʻano o ka hoʻohana i kuhikuhi ʻia e kēia valve, a hoʻomaʻemaʻe i ka lua o loko e pale ai i ka lepo mai ka hoʻopili ʻana a i ʻole ka hōʻino ʻana i nā ʻāpana sila.
②Mai hoʻopili i ka momona a i ʻole ka ʻaila ma ka ʻili o ka ʻili a me ka diaphragm e pale ai i ka pehu ʻana o ka lāʻau a pili i ke ola lawelawe o ka valve diaphragm.
③ʻAʻole ʻae ʻia ka huila lima a i ʻole ka mīkini hoʻoili no ka hāpai ʻana, a pāpā loa ʻia ke kuʻi ʻana.
④ Ke hoʻohana lima ʻoe i ka valve diaphragm, mai hoʻohana i nā lever kōkua e pale ai i ka torque kiʻekiʻe mai ka hōʻino ʻana i nā mea hoʻokele a i ʻole nā ʻāpana sila.
⑤ Pono e mālama ʻia nā kīwī diaphragm i loko o kahi lumi maloʻo a hoʻoheheʻe ʻia, pāpā loa ʻia ka hoʻopaʻa ʻana, pono e hoʻopaʻa ʻia nā ʻaoʻao ʻelua o ka valve diaphragm stock, a ʻo ka wehe a me ka pani ʻana i nā ʻāpana ma kahi ʻano wehe iki.
