Puka puka puka kūpaʻa
He aha ka resilient seated gate valve (RSGV)?
ʻO ka pahu puka puka noho kūpaʻa (RSGV),he kumumanaʻo hoʻolālā i mana nui i ka makemake no ka hoʻohana ʻana i nā ʻōnaehana hoʻolaha.
ʻO kapaʻa paʻa noho ʻīpuka valveloaʻa i kahi wili i hoʻopili piha ʻia me ka lāʻau EPDM i hoʻopaʻa mau ʻia i ka wedge a kū i ka ASTM D249.Hoʻopili ʻia ke kino valve, ka pāpale, a me ka pā palaka me ka fusion bonded epoxy (FBE), nani ke nānā aku a me ka pale maikaʻi loa.Hoʻokomo pū ʻia nā hoʻonohonoho koho i kahi Non-Rising Stem (NRS) a i ʻole Outside Screw & Yoke (OS&Y).Kiwi puka puka kūpaʻaHiki ke hoʻohana ʻia me kahi Spur a i ʻole Bevel Gear, a me ka mea hana uila.
nā ʻīpuka noho kūpaʻakaulana loa ia no ka hana ʻoihana.
- 1) Ke hoʻopaʻa ʻana maikaʻi: bi-directional bubble sealing.
- 2) ʻO ke kumu kūʻai haʻahaʻa: ua vulcanised ka noho ʻōpala ma ka wedge, ʻaʻohe pono no ka hana hou ʻana i ka noho valve.
- 3) Hoʻolālā maʻalahi a mālama maʻalahi
ʻO nā hiʻohiʻona nui o NORTECH resilient seated gate valve (RSGV)?
ʻO ke kino hana ʻia me ka hao ductile e ka hoʻoheheʻe pololei ʻana,Ua hoʻolālā ʻia e ka polokalamu 3D, me ka nānā ʻana i ka element finite no ka hale.
ʻO ke kumuhana ʻia me ke kila kila ma ka ʻōwili ʻana.ʻAno hoʻohui, e pale ana i ka hoʻohana ʻana i nā apo hapalua keleawe e hōʻemi i ke anawaena kumu.hoʻokuʻu ʻia ke ʻano alapiʻi maʻemaʻe i hoʻololi ʻia.ʻO ka poli aniani honua, kūpono ia i nā apo ʻO, e hōʻoia i ka ʻoluʻolu o ka hoʻololi a me ka torque liʻiliʻi.
ʻO ke kiʻi o kawilihana ʻia me ka hao ductile e ke one i kālai ʻia, uhi ʻia ka wili e ka EPDM holoʻokoʻa.
Hoʻohui ka papa 8.8 bolts i kapāpalea ʻo ke kino, ua uhi ʻia nā ʻupena e ka wax wela hoʻoheheʻe ʻia e pale ai i nā kī no ka ʻinoʻino.Hana ʻia ka pahu ma waena o ka pāpale a me ke kino me ka EPDM.Hoʻohana ʻia ka uhi valve me kahi ʻāpana paʻa, e hōʻoia ʻaʻole e hoʻokuʻu ʻia ka pahu pahu ma lalo o ke kaomi wai kiʻekiʻe.
ʻO ka hana kaiapuni
Hoʻopili ʻia ka ʻaoʻao o loko a me waho o ka valve me ka pauka epoxy maʻemaʻe e ka fusion bonded epoxy (FBE), ʻoi aku ka mānoanoa ma luna o 250um.He ikaika ka hoʻopili ʻana o ka uhi, ʻaʻole ia e luku ʻia ma lalo o ka hoʻāʻo ikaika o 3J.Hiki i nā ʻāpana kūloko ke hoʻokō me nā koi hoʻomalu kaiapuni, a hiki ke hoʻohana ʻia no ka wai inu, ka meaʻai a me ka lāʻau lapaʻau pololei.
Hana ʻia nā ʻāpana ʻāpana o ka EPDM a i ʻole NBR kiʻekiʻe, e like me nā koi wai inu, e pale ana i ka pilikia o ka ʻōpala maʻamau e hoʻohua ai i ka microorganism. nā huahana pili, akā ua ʻae ʻia hoʻi e WRAS ma UK a me ACS ma Farani. Hoʻopili ʻia ka ʻōpala a ʻōwili ʻia mai ke koʻokoʻo keleawe maʻamau (haʻahaʻa haʻahaʻa o ke kēpau), ʻaʻohe haumia i ka wai.
Hoʻokomo maʻalahi a hana
Hāʻawi mākou i nā ʻano like ʻole e like me ka pili flange, PVC pipe socket, uctile iron pipe socket, hōʻemi etc. Hiki ke hoʻonohonoho ʻia ka hoʻolālā pili kūikawā e like me nā noi
o na mea hoohana.Hiki ke hoʻohana ʻia nā kīwaha ʻīpuka e ka mea hoʻokele uila, nā huila lima, ka pāpale wili a i ʻole kī kūikawā.He mea maʻalahi ke kau ʻana i nā kiwi ma nā kūlana like ʻole o nā laina paipu.ma waho aʻe o ka hoʻonohonoho ʻana, hiki ke hoʻokomo ʻia nā valves.Ma kekahi mau wahi haiki, hiki iā ʻoe ke koho i ke ala hoʻonohonoho i kūpono no ka hana ʻana o nā valve.
Hiki ke pani paʻa ʻia ka valve a hiki i ka leakage me ka torque liʻiliʻi.ʻO ka torque hana maoli he 80% wale nō o ke anawaena, a hiki i nā kīwaha puka ke halihali i ka MST o 3 * DN NM Ua hala nā huahana i ka hoʻāʻo ola o 5000 mau manawa.No nā valves o ke anawaena nui, hiki iā mākou ke hāʻawi i nā mea hoʻopakele hana, e hōʻoia e hiki ke wehe a pani ʻia nā valve a pau e ke kanaka hoʻokahi.He ikaika ka huila lima, me nā ana kūpono, kūpono ia me ke kumu valve, ua like ke ʻano me nā mīkini kanaka, e hōʻoia i ka hana maʻalahi.
Mālama maʻalahi
Hiki ke hoʻololi i ke apo seal me ka ʻole o ka ʻoki ʻana i ka wai, ʻoi aku ka maʻalahi o ka mālama ʻana a hoʻemi i ka manawa mālama e like me ka hiki. apo.The max.ʻO ka torque hana ma lalo o ka mana.
