Pehea ka nui o kou ikekiwikā?
Introduction: ma o nā kūlana honua o nā huahana valve plastic a me nā ʻano hoʻāʻo o nā koi kumu waiwai, nā koi hoʻolālā a me nā koi hana, nā koi hana, ke ʻano hoʻāʻo, nā koi noi pūnaewele a me ka hoʻohana ʻana i ke kaomi a me ka mahana, etc., hiki i ka pilina ma waena ke hoʻomaopopo i ka pono. o ka plastic valve seal test, torque test and fatigue strength test and so on basic quality control control. ʻO nā koi o ka hoʻāʻo ʻana i ka hoʻāʻo ʻana i ka noho valve, ka hoʻāʻo ʻana i ke kino valve, ka hoʻāʻo ikaika kino valve, ka hoʻāʻo lōʻihi o ka valve, ka hoʻāʻo ikaika luhi a me ka torque hana e hōʻuluʻulu ʻia ma ke ʻano o nā papa. Ma o ke kūkākūkā ʻana o kekahi mau pilikia i nā kūlana honua, hopohopo nā mea hana a me nā mea hoʻohana i nā valve plastic. Me ka hoʻonui nui ʻana o ka pipeline plastic i loko o ka wai anuanu a me ka wai wela a me ka ʻenehana pipeline ʻoihana, ʻoi aku ka nui o ka mana o ka maikaʻi o ka pahu plastik i ka ʻōnaehana pipeline plastic. No ka mea, loaʻa i ka valve plastic ka maikaʻi o ke kaumaha māmā, ka pale ʻana i ka corrosion, ʻaʻohe adsorption scale, a me ka pilina pipeline plastic integration a me ka lōʻihi o ka lawelawe ʻana, ka valve plastic i ka lako wai (ʻoi aku ka wai wela a me ka hoʻomehana) a me ka hoʻohana ʻana i nā wai ʻē aʻe i ka pipeline plastic. ʻōnaehana, ʻaʻole hiki ke hoʻohālikelike ʻia kāna mau pono noi. I kēia manawa i ka hana ʻana i ka home a me ka hoʻohana ʻana i nā kīwī plastik, ʻaʻole ia he ala hilinaʻi, nā lako wai a me nā ʻili wai wai ʻē aʻe i hoʻohana ʻia i ka maikaʻi o ka huahana ʻoihana ʻaʻole kūlike, ʻo ka hoʻohana ʻenehana o ka lax paʻa a me ka leakage he mea koʻikoʻi, ke kūkulu ʻana i kahi plastic. ʻAʻole hiki ke hoʻohana i ka valve, pili i ka hoʻomohala holoʻokoʻa o ka noi paipu plastik. ʻO ke kūlana aupuni o ka valve plastic i ko mākou ʻāina i ke kaʻina hana, ua hana ʻia kāna huahana huahana a me ke ʻano maʻamau e like me ke kūlana honua. ʻO nā ʻano valve plastik honua ka nui o ka pōpō pōleʻa, butterfly valve, check valve, diaphragm valve a me globe valve, ʻo ke ʻano o ke ʻano nui o ʻelua, ʻekolu a me nā ʻano he nui, ʻo nā kumu kumu nui he ABS, PVC-U, PVC- C, PB, PE, PP a me PVDF a pela aku. I ke kūlana honua o nā huahana valve plastic, ʻo ka mea mua, pono nā mea maka i hoʻohana ʻia i ka hana ʻana o nā valves. Pono nā mea hana o nā mea maka e loaʻa i nā pihi hemahema e like me ke kūlana o nā huahana paipu plastik. I ka manawa like, ua kuhikuhi ʻia ka hoʻāʻo hoʻopaʻa ʻana, ka hoʻāʻo ʻana i ke kino valve, ka hoʻāʻo hana lōʻihi, ka hoʻāʻo ikaika luhi a me ka torque hana o ka valve holoʻokoʻa, a ʻo ke ola lawelawe hoʻolālā o ka valve plastic i hoʻohana ʻia no ka lawe ʻana i ka wai ʻenehana he 25 mau makahiki. ISO 15493: 2003 Plastics Piping Systems no ka hoʻohana ʻana i ka ʻoihana - ABS, PVC-U a me PVC-Pipe a me nā ʻōnaehana kūpono - Nā kikoʻī no ka paipu a me nā ʻōnaehana kūpono - ʻO nā kikoʻī no ka ʻāpana mua o ke kino valve, ka pāpale a me ka pāpale e like me ISO 15493: 2003 Plastics Piping Systems no ka hoʻohana ʻana i ka ʻenehana - ABS, PVC-U a me PVC-C - Pipe a me nā ʻōnaehana kūpono - Nā kikoʻī no ka ʻāpana mua o ke kino valve, ʻO ka pāpale a me ka pāpale e like me ka ISO 15493: 2003 Plastics Piping Systems no ka hoʻohana ʻana i ka ʻoihana - ABS, PVC-U a me PVC-C - Pipe and fitting Systems Metric series a me ISO 15494:2003 Plastics Piping Systems no ka hoʻohana ʻana i ka ʻoihana - PB, PE a me PP — Pipes and Fittings Systems specification — *** Māhele: Metric Series. A) Inā loaʻa i ka valve * kahi kuhikuhi, e hōʻailona ʻia me ka pua ma waho o ke kino valve. ʻO nā kiwi o ka hoʻolālā symmetrical e kūpono i ke kahe ʻelua ala a me ke kaʻawale. B) Hoʻokuʻu ʻia ka ʻāpana hoʻopaʻa ʻia e ka pahu valve e wehe a pani i ka valve. Pono e hoʻonoho ʻia ma ka hopena a i ʻole kekahi kūlana waena e ka friction a i ʻole actuator, a ʻaʻole hiki ke hoʻololi ke kaomi wai i kona kūlana. C) Wahi a EN736-3, ʻo ka lua liʻiliʻi loa i loko o ka lua valve e kūpono i kēia mau helu ʻelua: - no kēlā me kēia puka o ke kahe waena valve, ʻaʻole ia e emi ma lalo o 90% o ka waiwai DN valve; No nā kiwi i makemake ʻia e hōʻemi i ka puka waena, e haʻi ka mea hana i ka liʻiliʻi maoli ma o ka lua. D) Pono ke sila ma waena o ke kumu a me ke kino e like me EN736-3. E) E pili ana i ka pale ʻana o nā valves, e noʻonoʻo ka hoʻolālā ʻana o nā valve i ke ola lawelawe o nā ʻāpana kahiko, a i ʻole e hōʻike ka mea hana i nā ʻōlelo aʻoaʻo no ka hoʻololi ʻana i ka valve holoʻokoʻa. F) he 3m/s ke kahe kahe ana o na mea hana kiwi a pau. G) Ke nānā 'ia mai luna mai o ka valve, e pani ka pahu valve a i 'ole ka huila lima i ka valve clockwise. 3 Nā koi hana a) ʻO ka hana ʻana o nā mea i kūʻai ʻia e kūlike me nā kikoʻī o ka mea hana waiwai a hoʻokō i nā kūlana huahana. B) E hōʻailona ʻia ka code maka, ke anawaena DN a me ka PN nominal pressure ma ke kino valve. C) E kaha ʻia ke kino valve me ka inoa o ka mea hana a i ʻole ka hōʻailona. D) E kaha ʻia ke kino valve me ka lā o ka hana ʻana a i ʻole ka helu helu. E) E kaha ʻia ke kino valve me ke code o nā wahi like ʻole o ka mea hana. 4 nā koi hana pōkole pōkole i ka hana maʻamau o ka huahana he mea nānā i nā mea hana, ʻo ka mea nui e hana i ka hoʻāʻo hoʻopaʻa ʻana o ka noho valve a me ka hoʻāʻo hoʻopaʻa ʻana i ke kino, hoʻohana ʻia e nānā i ka hana hoʻopaʻa ʻana o nā kiwi plastik, nā kiwi plastik e hiki ai. ʻAʻole hiki ke loaʻa ka leaka o loko (valve seat leakage), ʻaʻole hiki ke loaʻa ka leakage waho (valve leakage). ʻO ka hoʻāʻo hoʻopaʻa ʻana i ka noho valve e hōʻoia i ka hana ʻana o ka ʻōnaehana hoʻokaʻawale valve; ʻO ka hoʻāʻo ʻana o ke kino valve e hōʻoia i ka leakage o ka sila a me ka sila hui valve. Hoʻopili ʻia ka ʻōnaehana palaki a me ka pipeline e ka pilina pili: ʻo ke anawaena o waho o ka ʻāpana pili valve e like me ke anawaena o waho o ka paipu, a ʻo ka ʻaoʻao hope o ka ʻaoʻao pili valve e welded e pili ana i ka maka hope o ka paipu; ʻO ka pilina paʻa socket: ʻo ka ʻāpana hoʻohui o ka valve ma ke ʻano o ka socket, i hoʻopaʻa ʻia me nā paipu paipu; ʻO ke kumu hoʻoheheʻe uila: ʻo ka ʻāpana pili valve ka ʻano kumu me ka uwea hoʻomehana uila ma ke anawaena o loko, a ua hoʻohui ʻia me ka paipu; Hoʻoheheʻe wela wela: ʻo ka ʻāpana pili valve ke ʻano kumu, a ua pili ka paipu me ke kumu hoʻoheheʻe wela; Socket hoʻopili pili: ʻo ka ʻāpana pili valve ma ke ʻano o ke kumu, a ʻo ka paipu i hoʻopaʻa ʻia i ka pilina pili; ʻO ke apo hoʻopaʻa hoʻopaʻa paʻa paʻa: ʻo ka ʻāpana pili valve ke ʻano o ke apo hoʻopaʻa hoʻopaʻa i hoʻopili ʻia, a pili ka paipu me ke kumu; Hoʻohui Flange: ʻo ka ʻāpana pili valve ma ke ʻano o ka flange, pili me ka flange ma ka paipu; ʻO ka pilina pili: ʻo ka ʻāpana pili valve ma ke ʻano o ke kaula, i hoʻopili ʻia me ke kaula ma ka paipu a i ʻole nā mea paipu; Hoʻohui ola: ʻo ka ʻāpana pili o ka valve ma ke ʻano o ka pilina ola, a ua pili ka paipu a i ʻole nā paipu paipu. Hiki ke hana ʻia nā pilina like ʻole ma ka valve hoʻokahi. Me ka piʻi ʻana o ka mahana, pono e hoʻopōkole ʻia ke ola lawelawe o nā pahu plastik. No ka mālamaʻana i ke ola lawelawe like, ponoʻoe e ho'ēmi i ke kaumaha o ka lawelawe.
Pehea ka nui o kāu ʻike e pili ana i nā valves?
Hoʻokomo nui ʻia nā flanges paipu i ka integral (IF), wili palahalaha pā (PL), wiliwili ʻāʻī ʻāʻī (SO), wiliwili ʻāʻī ʻāʻī (WN), wiliwili kumu (SW), wiliwī (Th), apo wiliwili kīwaha lima lima lima (PJ/SE). )/(LF/SE), apo kuʻilima palahalaha lima lima (PJ/RJ) a me ka uhi flange (BL), etc.
