ʻĀpana hana ākea
ʻO nā valve lawelawe maʻamau ka mea i hoʻolālā ʻia no nā hana maʻamau me nā helu haʻahaʻa haʻahaʻa ma ka papa ANSI 150 a 600 (diameter DN16 a DN100) a me nā pae wela haʻahaʻa mai -50 a 650H (-46 a 343 c). E lele i ka media corrosive a me ka hāʻule kaomi maʻamau me ka ʻole o ka cavitation a me ka uila. Hoʻolālā ʻia nā valve lawelawe maʻamau me kahi degere o ka hoʻololi a me ka hoʻololi ʻana e hiki ai
Hoʻohana ʻia lākou i nā kūlana koʻikoʻi. Hōʻike ʻia nā mea kino e like me ke kila kalapona a me ke kila kila. Hōʻike ka Kiʻi 1.9 i kahi moʻolelo o ʻelua mau pahu hana maʻamau, hoʻokahi i hana lima ʻia a hoʻokahi ʻakomi.

Pahu hana kūikawā
ʻO nā valves lawelawe kūikawā nā valve i hanaʻia no nā noi hoʻokahi kahi i manaʻoʻoleʻia nā hana hana maʻamau. Ma muli o kāna hoʻolālā kūikawā a me ka hana ʻana, hiki ke hana ʻia ma lalo o nā ʻāpana hana kūikawā a me nā kūlana hana. Hoʻohana pinepine ʻia kēia ʻano no ka hoʻoponopono ʻana i kahi mahana i makemake ʻia, kiʻekiʻe, a i ʻole waena ma ka hoʻāʻo ʻelua. FIG. Hōʻike ka 1.10 i kahi pahu hoʻomalu i hoʻolālā ʻia me ke kino i ʻoki māmā ʻia a me ka spool seramika e mālama ai i nā kūlana mineral ʻeleʻele e pili ana i nā ʻāpana one a me ka ea kaomi kiʻekiʻe.

ʻO ka valve lawelawe koʻikoʻi
ʻO ka valve hana koʻikoʻi, nona nā hiʻohiʻona kūikawā no ka mālama ʻana i nā mea hoʻoheheʻe ʻia, ka hoʻoheheʻe ʻana o ke kaomi kiʻekiʻe e hopena i ka cavitation koʻikoʻi, flash, blockage a i ʻole kiʻekiʻe leo. Hiki ke hoʻolālā maikaʻi ʻia ka valve ma ka spool valve globe. A i ʻole ka diski kūikawā; A i ʻole e hoʻokomo ʻia nā pōpō kūikawā i nā pahu wili e hōʻemi a pale i ka hopena i ka wā o ka hana. Eia kekahi, koi nā mea hoʻokele a i ʻole nā ​​​​mea hana hana i nā mea hana kūikawā e lanakila ai i ka ikaika o ka hana. FIG. Hōʻike ka 1.11 i kahi pahu lawelawe koʻikoʻi e hiki ke mālama i ka 1100H (593 c) wai calcium me nā spool lehulehu
Hoʻohana i ka hāʻule puʻe kiʻekiʻe me ka pāpale pale hoʻoluʻu kūikawā. Hiki i ka electro-hydraulic actuator ke hana i ka 20,000 lb (889600N) o ka pahu.
ʻO nā puʻupuʻu kīpē i hoʻohana maʻamau ʻia nā gaskets non-metallic gaskets, semi-metal gaskets a me metala gaskets. Non-metallic gasket i ʻike ʻia he gasket, e like me ka asbestos rubber sheet, rubber, ptfe, etc., gasket no ka mahana, ʻaʻole nā ​​manawa kiʻekiʻe. Hoʻokumu ʻia ka gasket semi-metal me nā mea metala a me nā mea metala ʻole, e like me ka graphite composite gasket, winding gasket, metal coated gasket a pēlā aku. Hāʻawi ka pahu semi-metal i kahi ākea ākea o ka mahana a me ke kaomi ma mua o ka gasket non-metal. Hana ʻia nā ʻeke metala a pau i ka metala, me ke ʻano o ka nalu, ke ʻano niho, elliptic, octagonal, lens pad, cone pad a pēlā aku. Metal gasket no ke kiʻekiʻe wela a me ke kiʻekiʻe kaomi noi. 1 Nā Kūlana o ka hoʻohana ʻana i nā pahu hao hao ʻole E ʻike i ka Papa 1-4-1 no nā kūlana o ka hoʻohana ʻana i nā pahu hao hao ʻole. -40 ~ 100D nitrile lāʻau nbr2.0-30 ~ 110 styrene butadiene lāʻau sbr2.0-30 ~ 100 ethylene propylene lāʻau epdm2.0-40 ~ 130 fluorine lāʻau Viton2.0- 50 ~ 200 asbestos lāʻau lapaʻau XB350X0020NY4 Papa 1-4-2 Papa graphite composite hikiwawe Nā Kūlana o ka hoʻohana ʻana i ka pā Core a me nā mea hoʻopaʻa ʻia ʻO ka haʻahaʻa carbon Steel Pressure papa MPa 2.0 a i 11.0 (150 a 600) ʻO ka wela kūpono ° C 450OCR18Ni92.0 a i 11.0 (150 a 600)650* Nānā: * No ka mea hoʻoheheʻe ʻia ma lalo o 450 ° C
