Hoʻohana ʻia ʻo API 594 Dual plate check valve no nā pipeline maʻemaʻe a me ka ʻoihana, ka mālama ʻana i ke kaiapuni, ka mālama ʻana i ka wai, ka lako wai a me nā paipu hoʻoheheʻe wai i nā hale kiʻekiʻe e pale i ka hoʻohuli ʻana o ka media.Hoʻohana ka valve check i kahi ʻano wafer, ʻelua semicircles ka papa butterfly, a hoʻohana i kahi pūnāwai e hoʻoikaika i ka hoʻihoʻi hou ʻana, hiki i ka ʻili o ka sila ke lilo i ke kino i luna o ka wiliwili ʻana i nā mea ʻaʻahu a i ʻole ka uhi ʻana i ka lāʻau, ākea ka laulā, a ʻo ka hoʻopaʻa ʻana. hilinaʻi.
ʻO ka wehe ʻana a me ka pani ʻana o ka API 594 check valve hilinaʻi i ke kahe a me ka ikaika o ka mea waena e wehe a pani paha iā lākou iho i mea e pale ai i ke kahe ʻana i hope.Ua kapa ʻia ka valve check valve.Loaʻa i ka ʻāpana o nā valves ka nānā ʻana i nā valves, kahi i hoʻohana nui ʻia i nā pipeline kahi e kahe ai ka medium i hoʻokahi ʻaoʻao, a ʻae wale i ke kahe e kahe i ka ʻaoʻao hoʻokahi e pale ai i nā pōʻino.
E like me ke ʻano o ka valve check, hiki ke hoʻokaʻawale ʻia i ʻekolu ʻano: lift check valve, swing check valve and wafer check valve.Hiki ke hoʻokaʻawale ʻia nā kiwi hoʻokiʻekiʻe kiʻekiʻe i ʻelua ʻano: kū pololei a me ka pae.Hoʻokaʻawale ʻia nā kiwi hoʻopaʻa koʻi i ʻekolu mau ʻano: hoʻokahi valve, pālua pālua a me multivala.He ʻano pololei ka wafer check valve.ʻO ka valve check he kiwikā e hiki ke pale ʻakomi i ka wai mai ke kahe ʻana i hope.Wehe ʻia ka pā o ka valve check ma lalo o ka hana o ke kaomi wai, a kahe ka wai mai ka ʻaoʻao inlet a i ka ʻaoʻao puka.Ke emi iho ke kaomi ma ka ʻaoʻao inlet ma mua o ka ʻaoʻao puka, ua pani ʻia ka pā valve ma lalo o ka hana o ka ʻokoʻa o ke kaomi wai, ka umekaumaha a me nā mea ʻē aʻe e pale ai i ka kahe ʻana o ka wai.
Inā makemake ʻoe i nā kikoʻī hou aku e pili ana i nā valves e ʻoluʻolu e kelepona i kā mākou keʻena kūʻai
