Ductile Iron Soft Seal Gedhi VS.Ductile Iron Yakaoma Seal Gedhi Valve
Soft seal gedhi mavharuvhu uye akaoma chisimbiso gedhi mavharuvhu anowanzo shandiswa midziyo yekudzora uye kuvharira kuyerera, ese ane yakanaka yekuisa chisimbiso, kushandiswa kwakasiyana-siyana, uye ndechimwe chezvigadzirwa zvinotengwa nevatengi zvakanyanya.Mamwe manovice ekutenga anogona kunge achida kuziva, zvakafanana nevhavha yegedhi, ndeupi musiyano uripo pakati pavo?
Chisimbiso chakapfava chisimbiso pakati pesimbi nechisiri-simbi, nepo chisimbiso chakaoma chisimbiso pakati pesimbi nesimbi.Yakapfava seal gedhi vharafu uye yakaoma chisimbiso gedhi vharafu zvinhu zvekuisa chisimbiso, chisimbiso chakaomarara chakagadzirwa nemashini ane chigaro zvinhu kuti ive nechokwadi chechokwadi chekuenderana ne spool (bhora), kazhinji simbi isina tsvina nemhangura.Chisimbiso chakapfava chakaiswa muvharuvhu yekuvharisa chigaro chinhu chisiri chesimbi, nekuda kweiyo yakapfava yekuisa chisimbiso ine imwe dhigirii yekunyungudika, uye nekudaro iyo yekugadziriswa kweiyo zvinodiwa ikati yakadzikira pane chisimbiso chakaoma.Pazasi tora iwe kuti unzwisise musiyano pakati pesoft seal gedhi vharafu uye yakaoma chisimbiso gedhi vharafu.
Kutanga kuisa chisimbiso zvinhu
1. Zvinhu zviviri zvekuisa chisimbiso zvakasiyana.Soft seal gedhi vharafu inowanzoita rabha kana PTFE uye zvimwe zvinhu.Hard sealing gedhi vharafu uchishandisa simbi isina tsvina uye mamwe masimbi.
2. Chisimbiso chakapfava: kuvhara vice side remativi maviri echinhu chesimbi, rumwe rutivi rwe elastic non-metallic materials, inozivikanwa se "soft seal".Iyo yekuisa chisimbiso yeakadaro gedhi mavharuvhu, asi kwete yakakwirira tembiricha, nyore kupfeka uye kubvarura, uye urombo michina zvinhu.Zvakadai sesimbi + rabha;simbi + PTFE uye zvichingodaro.
3. Chisimbiso chakaoma: chisimbiso chakaoma uye chisimbiso kumativi ose isimbi kana zvimwe zvinhu zvakaoma.Kuvhara vharafu kwakadai kwegedhi kwakashata, asi kupikisa kwepamusoro-tembiricha, kusagadzika, uye zvinhu zvakanaka zvemichina.Zvakadai sesimbi + simbi;simbi + mhangura;simbi + graphite;simbi + alloy simbi;(inogonawo kushandisa simbi yakakandwa, alloy simbi, spray pendi alloy, nezvimwewo).
Chechipiri, nzira yekuvaka
Indasitiri yemagetsi ine nharaunda yebasa yakaoma, mazhinji ayo ari ekupedzisira-akaderera tembiricha uye yakaderera kudzvanywa, yakakwirira midhiya kuramba, uye inoparadza.Ikozvino, kufambira mberi kwetekinoroji kwakatungamira mukuzivikanwa kwemavharuvhu egedhi rakaomarara.
Kuti titarise hukama pakati pekuoma kwesimbi, chisimbiso chegedhi rakaomarara, uye chisimbiso chakapfava, muviri wevharuvhu unofanirwa kuomeswa, uye ndiro yevharuvhu nechigaro chevharuvhu kuti irambe ichikuya kuti iwane kuvharwa.Iyo yakaoma chisimbiso gedhi revhavha yekugadzira kutenderera kwakareba.
Chechitatu, kushandiswa kwemamiriro ezvinhu
1, chisimbiso chakapfava chinogona kuona zero kuvuza, chisimbiso chakaoma chinogona kugadziridzwa zvinoenderana nezvinodiwa zvepamusoro uye zvakaderera;
2, Zvisimbiso zvakapfava zvinogona kudonha pasi pekupisa kwakanyanya, zvinoda kutarisisa kudzivirira moto, uye zvisimbiso zvakaomarara hazvibvire pasi pekupisa kwakanyanya.Iyo yekukurumidzira yekuvhara-vhavha yakaoma chisimbiso inogona kushandiswa mukumanikidza kwakanyanya, iyo yakapfava chisimbiso haigone kushandiswa.
3, kune mamwe midhiya inoparadza, chisimbiso chakapfava hachigone kushandiswa, unogona kushandisa chisimbiso chakaoma;
4, mune yekupedzisira-yakaderera tembiricha, zvinyoro zvisimbiso zvinhu zvichave nekudonha, chisimbiso chakaoma harisi dambudziko rakadaro;
Chechina, kusarudzwa kwemidziyo pa
Matanho ese ekuisa chisimbiso anogona kusvika matanhatu, kazhinji zvichienderana nepakati pekuita, tembiricha, uye kudzvanywa kuti usarudze iyo chaiyo gedhi vharafu.Kune midhiya yakawanda ine zvimedu zvakasimba kana abrasive, kana kana tembiricha inopfuura 200 degrees, zviri nani kusarudza chisimbiso chakaoma.Kana iyo torque yevhavha yekuvhara yakakura, iwe unofanirwa kusarudza kushandisa yakagadziriswa yakaoma seal gedhi valve.
shanu, musiyano muhupenyu hwebasa
Kubatsira kwechisimbiso chakapfava chisimbiso chakanaka, icho chinokanganisa ndechekuti zviri nyore kukwegura, kupfeka uye kubvarura, hupenyu hupfupi.Hupenyu hwekusunga chisimbiso hwakaoma hwakareba, uye kuita kwekuisa chisimbiso kwakaipa pane kuvharika kwakapfava, izvo zviviri zvinogona kuzadzana.
Izvo zviri pamusoro apa mutsauko pakati pesoft seal gedhi vharafu uye yakaoma chisimbiso gedhi vharafu ruzivo kugovana, ndinotarisira kukwanisa kukubatsira mubasa rekutenga.
