Ntchito ya Valve Gasket & Guide Guide

Ma valve gaskets adapangidwa kuti aletse kutayikira komwe kumachitika chifukwa cha kupanikizika, dzimbiri, komanso kukulitsa / kutsika kwamafuta pakati pazigawo. Ngakhale pafupifupi flangedkulumikizana's ma valve amafuna ma gaskets, momwe amagwiritsira ntchito ndi kufunikira kwake kumasiyana ndi mtundu wa valve ndi mapangidwe. Mu gawo ili,TWSidzafotokozera malo oyika ma valve ndi kusankha kwa zinthu za gasket.

I. Kugwiritsa ntchito koyamba kwa ma gaskets kuli pa malo olumikizirana ma valve.

Ma valve ogwiritsidwa ntchito kwambiri

1. Chipata cha Chipata
2. Globe Valve
3. Valve ya butterfly(makamaka valavu yagulugufe yowoneka bwino komanso yopindika iwiri)
4. Onani valavu

Mu ma valve awa, gasket sagwiritsidwa ntchito poyendetsa kayendetsedwe kake kapena kusindikiza mkati mwa valve yokha, koma imayikidwa pakati pa ma flanges awiri (pakati pa flange ya valve yokha ndi chitoliro cha chitoliro). Mwa kulimbitsa ma bolts, mphamvu yothina yokwanira imapangidwa kuti ipange chisindikizo chokhazikika, kuteteza kutayikira kwa sing'anga pakulumikiza. Ntchito yake ndikudzaza mipata yaying'ono yosagwirizana pakati pa zitsulo ziwiri zachitsulo, kuonetsetsa kuti 100% isindikizidwe pakugwirizana.

II.Kugwiritsa ntchito Gasket mu Valve "Valve Cover"

Mavavu ambiri amapangidwa ndi matupi osiyana siyana ndi zotchinga kuti zisamavutike kukonza mkati (monga kusintha mipando ya valavu, mavavu a disc, kapena zinyalala zochotsa), zomwe kenako zimangiriridwa pamodzi. Gasket imafunikanso pa kugwirizana uku kuti zitsimikizidwe zolimba.

1. Kulumikizana pakati pa chivundikiro cha valve ndi thupi la valve la valve yachipata ndi valve yapadziko lonse nthawi zambiri kumafuna kugwiritsa ntchito gasket kapena O-ring.
2. Gasket yomwe ili pamalopo imagwiranso ntchito ngati chisindikizo chokhazikika kuteteza sing'anga kuti zisatayike kuchokera ku thupi la valve kupita mumlengalenga.

III. Gasket yapadera yamitundu yeniyeni ya valve

Ma valve ena amaphatikiza gasket ngati gawo la msonkhano wawo wosindikiza, wopangidwa kuti uphatikizidwe mkati mwa ma valve.

1. Valve ya butterfly- valve mpando gasket

• Mpando wa valavu agulugufe kwenikweni ndi mphete gasket, amene mbamuikha mu khoma lamkati la valavu thupi kapena kuikidwa kuzungulira chimbale butterfly.
• Pamene gulugufediskikutseka, imakanikiza mpando wa valve gasket kupanga chisindikizo champhamvu (monga gulugufediskikuzungulira).
• Zomwe zimakhala ndi rabala (mwachitsanzo, EPDM, NBR, Viton) kapena PTFE, zomwe zimapangidwa kuti zigwirizane ndi ma TV ndi kutentha.

2. Vavu ya Mpira- Valve Seat Gasket

• Mpando wa valve wa valve ya mpira ndi mtundu wa gasket, womwe umapangidwa kuchokera ku zipangizo monga PTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), kapena mapulasitiki olimbikitsidwa.
• Amapereka chisindikizo pakati pa mpira ndi thupi la valve, akutumikira monga chisindikizo chokhazikika (chokhudzana ndi thupi la valve) ndi chisindikizo champhamvu (chokhudzana ndi mpira wozungulira).

IV. Ndi ma valve ati omwe nthawi zambiri sagwiritsidwa ntchito ndi ma gaskets?

1. Ma valve otenthetsera: Thupi la valve limalumikizidwa mwachindunji ku payipi, kuthetsa kufunikira kwa ma flanges ndi ma gaskets.
2. Mavavu okhala ndi ulusi wolumikizira: Nthawi zambiri amagwiritsa ntchito kusindikiza kwa ulusi (monga tepi yaiwisi kapena sealant), nthawi zambiri kumachotsa kufunikira kwa ma gaskets.
3. Mavavu a Monolithic: Ma valve ena otsika mtengo kapena ma valve apadera amakhala ndi thupi lofunikira lomwe silingathe kupasuka, motero mulibe chotchinga cha valve.
4. Mavavu okhala ndi mphete za O kapena ma gaskets okutidwa ndi zitsulo: Pazovuta kwambiri, kutentha kwambiri, kapena ntchito zapadera zapakatikati, njira zosindikizira zapamwamba zimatha kulowa m'malo mwa ma gaskets osakhala achitsulo.

V. Chidule:

Valve gasket ndi mtundu wazinthu zonse zodulira makiyi osindikiza, amagwiritsidwa ntchito kwambiri polumikizira mapaipi a ma valve osiyanasiyana a flange, komanso amagwiritsidwa ntchito posindikiza chivundikiro cha mavavu ambiri. Pakusankhidwa, ndikofunikira kusankha zida zoyenera za gasket ndikupanga molingana ndi mtundu wa valavu, njira yolumikizira, sing'anga, kutentha ndi kupanikizika.
