Hoʻopaʻa paʻa ʻana i nā kiwi plastik

ʻO ka hana sila ʻana o ahoʻokahi union ball valve x9201-t keʻokeʻoe pili ana i ka hiki o ka sila valve e pale aku i ka leakage waena, a ʻo ia ka mea koʻikoʻi o ka ʻenehana hana ʻenehana o ka valve.Hiki i ka leakage media ke lilo i mea waiwai, haumia kaiapuni a me nā pōʻino.No nā mea pahū, pahū, ʻona a i ʻole radioactive media, ʻo ka hana hoʻopaʻa ʻana o ka valve i ʻae ʻole ʻia e leak e pili ana i ka hiki o ke sila valve e pale i ka leakage media, ʻo ia ka mea nui o ka ʻike loea o ka valve.Hiki i ka leakage media ke lilo i mea waiwai, haumia kaiapuni a me nā pōʻino.No ka mea pahū, pahū, ʻona a i ʻole ka radioactive media, ʻaʻole ʻae ʻia ka leakage, no laila pono i ka valve ke hoʻokō pono i ka sila.

Ua ulu nui ka ʻenehana hoʻopaʻa ʻana i ka valve mai kona hānau ʻana a hiki i kēia manawa.I kēia manawa, hoʻokomo nui ʻia ka ʻenehana sealing valve i ʻelua ʻano, ʻo ia hoʻi ka static sealing a me ka dynamic sealing.ʻO ka hoʻopaʻa paʻa ʻana e pili ana i ka hoʻokumu ʻana i kahi sila ma waena o ʻelua mau ʻāpana paʻa.ʻO ke ala nui o ka hoʻopaʻa ʻana ʻo ka hoʻohana ʻana i nā gaskets.Nui nā ʻano gaskets, hoʻohana mau ʻia kēia mau mea.

① Mea holoi paʻa: kahi holoi paʻa ma waena o ʻelua ʻāpana paʻa.Hoʻokaʻawale maʻamau i loko o nā mea holoi paʻa paʻa, nā mea holoi paʻa paʻa, nā mea holoi paʻa metala a me nā mea holoi paʻa paʻa e like me nā mea i hoʻohana ʻia.

②O-ring: kahi mea holoi me ka ʻāpana keʻa O-ring.No ka mea, ʻo kona ʻano cross-sectional he ʻano O, loaʻa iā ia kahi hopena paʻa ponoʻī, no laila ʻoi aku ka maikaʻi o ka hopena hoʻopaʻa ʻana ma mua o ka gasket flat.

③ Mea holoi: He mea holoi e wili ai i kekahi mea ma kekahi mea.Loaʻa ka elasticity maikaʻi o ia mau gaskets a hiki ke hoʻonui i ka hopena sealing.

④ Mea holoi ʻano kūikawā: kahi mea holoi me ke ʻano like ʻole.Me nā mea holoi oval, nā mea holoi daimana, nā mea holoi lole, nā mea holoi dovetail, a me nā mea ʻē aʻe.

⑤ Nā mea holoi nalu: nā mea holoi nalu.ʻO kēia ʻano gasket ka mea maʻamau i nā mea metala a me nā mea non-metallic, a loaʻa nā ʻano o ka ikaika hoʻoemi liʻiliʻi a me ka hopena sila maikaʻi.

⑥ Mīkini holoi ʻōwili: ʻO ke kāʻei metala lahilahi a me ke kāʻei metala ʻole e pili pono ana e hana i ka mīkini holoi.He elasticity maikaʻi kēia gasket a me ka hana hoʻopaʻa sila maikaʻi.Dynamic sealing He ʻano pilikia sila i ka wā o ka neʻe ʻana o ka valve.ʻAʻole ia e ʻae i ke kahe waena e kahe me ka neʻe ʻana o ke kumu valve.ʻO ke ala nui o ka hoʻopaʻa ʻana, ʻo ia ka hoʻohana ʻana i kahi pahu pahu.ʻElua ʻano kumu o nā pahu hoʻopiha: ʻano gland a me nā ʻano nut compression.ʻO ka ʻano gland ka mea i hoʻohana nui ʻia i kēia manawa.Ma ka ʻōlelo maʻamau, hiki ke hoʻokaʻawale ʻia ka gland i ke ʻano hui a me ke ʻano integral.ʻOiai ʻokoʻa kēlā me kēia ʻano, aia i loko o ke kaomi o ka bolt.Hoʻohana mau ʻia nā ʻano nut compression no nā valve liʻiliʻi.Ma muli o kona liʻiliʻi liʻiliʻi, ua kaupalena ʻia ka ikaika hoʻoemi.I loko o ka pahu hoʻopiha, no ka mea pili pololei ka paʻi ʻana me ke kumu valve, ʻo nā koi āpau no ka hoʻopili ʻana he sila maikaʻi, haʻahaʻa friction coefficient, hiki ke hoʻololi i ke kaomi a me ka mahana o ka waena, a me ke kūpaʻa ʻana.I kēia manawa, ʻo nā mea hoʻopihapiha maʻamau i hoʻohana ʻia he ʻano-O-ka

Ring, PTFE wili puʻupuʻu, asbestos paʻi ʻana a me ka paʻi ʻilika.Loaʻa i kēlā me kēia ʻano paʻi kona mau kūlana kūpono a me ka laulā, hiki ke koho ʻia e like me nā pono kikoʻī.
