Mfundo yogwiritsira ntchito ndikugwiritsa ntchito valve ya kelly ndi chiyani?

1. Cholinga cha valve kelly

Valve ya kelly ndi valavu yowongolera pamakina obowoleza zingwe ndipo ndi imodzi mwa zida zothandiza kupewa kuphulika.Ma valve a Kelly amatha kugawidwa kukhala ma valve apamwamba a kelly ndi ma valve otsika a kelly.Chovala chapamwamba cha kelly chimagwiritsidwa ntchito pakati pa mapeto apansi a faucet ndi kelly;valavu yapansi ya kelly imagwiritsidwa ntchito pakati pa mapeto apansi a kelly ndi mgwirizano wa chitetezo cha kelly.Kubowola madzimadzi kumatha kuyenda momasuka kudzera pa valavu ya kelly popanda kutsika.Gwiritsani ntchito wrench yapadera kuti mutembenuzire 90 ° molingana ndi malangizo kuti muyitse ndikuyimitsa.

2. Mapangidwe a valve Kelly ndi mfundo yogwirira ntchito

Kumtunda ndi kumunsi kwa kelly valve kumapangidwa ndi thupi, mpando wapansi wa mpira, kasupe, kiyi yogwiritsira ntchito, valavu ya mpira, mphete yotsegula yotsegula, mpando wapamwamba wa mpira, mphete yosungira, mphete yosungiramo zotanuka ndi chisindikizo. , wrench yowonjezera, etc. Mfundo yosindikizira ndi yakuti kasupe amathandizira mpando wa mpira kuti ukhazikitse mpirawo ndikuupangitsa kukhala ndi preload inayake.Mpira ndi chisindikizo cha mpando wa mpira zimagwirizana kwambiri.Mpira ukatulutsidwa, maso amadzi amakhala osatsekeka.Ikatsekedwa, malo ozungulira amatsekera maso onse amadzi.Kupanikizika kwa annulus wamkati kumachita pa mpira, kupanga mpira ndi mpando wa mpira mu chikhalidwe chosindikizira kwambiri.

3. Momwe mungagwiritsire ntchito valve ya kelly

(1) Musanagwiritse ntchito, gwiritsani ntchito wrench yapadera kuti mutembenuzire kiyi yogwiritsira ntchito kuti muwone ngati imatha kusinthasintha, m'malo kapena kunja;

(2) Pambuyo polumikiza malekezero apamwamba ndi apansi a kelly, gwiritsani ntchito wrench kachiwiri kuyesa kusinthasintha kwa makiyi ogwiritsira ntchito musanatsike pachitsime;

(3) Pamene kukankha kapena kuphulika kumachitika pa kelly pachitsime, valavu ya pulagi ya pamwamba kapena yapansi ya kelly iyenera kutsekedwa pamalo apafupi;

(4) Panthawi yogwira ntchito bwino, tsekani valavu ya pulagi yapansi musanatulutse kelly kuti muteteze madzi akubowola kuti asaponye pansi;

(5) Kuumirira kutsegula ndi kutseka tambala pamwamba ndi pansi pa kelly nthawi zonse.Mwachitsanzo, polumikiza chidutswa chimodzi kapena kugwiritsa ntchito matambala osunthika apamwamba ndi apansi a kelly pafupipafupi, kuti asachite dzimbiri komanso osatha kutsegula ndi kutseka bwino;

(6) Pambuyo polumikiza chidutswa chimodzi, valavu yotsekedwa iyenera kutsegulidwa mu nthawi kuti asagwire mpope poyambitsa mpope;

(7) Wrench ya plug valve iyenera kuyikidwa kutali ndi chitsime kuti isagwere pachitsime kapena kutayika;

(8) Posankha valavu ya pulagi, onetsetsani kuti kupanikizika kwake kwakukulu kogwira ntchito kumagwirizana ndi kuthamanga kwa gulu loteteza chitsime.
