Kodi Grooved Fittings & Couplings Ndi Chiyani?

Zolumikiza zomangika ndi zolumikizira mapaipi otayika. Kuti apange, mphete zapadera zosindikizira ndi zomangira zimatengedwa. Sichifuna kuwotcherera ndipo angagwiritsidwe ntchito kukhazikitsa zosiyanasiyana chitoliro mitundu. Ubwino wa malumikizidwe amenewa ndi disassembly awo, komanso kudalirika kwambiri, nthawi zina kuposa zizindikiro zofanana welded ndi glued mfundo.

Magulu a Groove adapangidwa kalekale. Mu Nkhondo Yoyamba Yapadziko Lonse, adagwiritsidwa ntchito kukhazikitsa mapaipi okhala ndi chisakanizo choyaka moto, chomwe chimagwiritsidwa ntchito poponya moto. Kuyambira nthawi imeneyo, akhala akugwiritsidwa ntchito pazinthu zosiyanasiyana zamtendere zomwe zimagwirizana ndi zodalirika komanso zapamwamba.

Mukayika payipi, chidwi chapadera chimaperekedwa pazolumikizana. Kukhazikika ndi kudalirika kwa dongosololi, kutha kupirira katundu wapamwamba kwambiri, komanso kumasuka kwa kukonza kotsatira zimadalira iwo. Kwa nthawi yayitali, kulumikizana kwa ulusi ndi kuwotcherera kumagwiritsidwa ntchito ngati njira zazikulu zoyikapo. Masiku ano, ma grooved couplings - zomangira zotsekeka zokhala ndi kolala yosindikiza - zikutchuka. Thupi la chotchinga choterocho limapangidwa ndi chitsulo cha ductile kapena chitsulo cha kaboni, ndipo choyikapocho chimapangidwa ndi zinthu zosagwirizana ndi mphira.

Malingana ndi katundu, zogwirizanitsa zimapangidwa ndi chitsulo choponyedwa, carbon steel ndi zipangizo zina zofanana. Kulumikizana kumapangidwa ndi ma halves awiri ndi zotanuka polima O-ring (khafu). Mapaipi okhala ndi grooves (grooves) amalumikizidwa mndandanda, ophatikizana ndi olowa, ndipo malo osinthira amaphimbidwa ndi chisindikizo cha o-ring.

M'mawonekedwe apachiyambi, ma groove ophatikizira ma groove adadulidwa ndi odula mphero. Inali njira yovuta komanso yovuta. Masiku ano, chida chapadera chimagwiritsidwa ntchito popanga grooves - roller groovers. Amasiyana ndi njira yoyendetsera (pamanja kapena hydraulic) komanso m'mimba mwake ya mapaipi omwe amatha kugwira nawo ntchito. M'mafakitale, makina opangira grooving amagwiritsidwa ntchito, omwe ndi okwera mtengo kwambiri kuti agwiritsidwe ntchito kunyumba. Koma pazigawo zing'onozing'ono za ntchito kapena ntchito yokonza chizolowezi, ntchito ya chida chamanja ndi chokwanira.

Chotsalira chokha cha ma groove joints ndi mtengo wawo wapamwamba, wapamwamba kuposa mitundu ina. Izi ndi zomwe zimalepheretsa kugwiritsidwa ntchito kwawo kofala. Zida zopangira zitoliro ndizokwera mtengo; mitengo yonyamula katundu imawononga ma ruble masauzande angapo. Koma pa ntchito zazing'ono, mukhoza kubwereka chida; mwamwayi, kudziwa bwino ntchito ndi groover sikovuta kwenikweni.

Mitundu ya zopangira groove

Mfundo ya grooved fittings imagwiritsidwa ntchito pokwaniritsa ntchito zosiyanasiyana panthawi yoyika mapaipi. Pali mitundu ingapo ya zotengera zotere:

• kugwirizana - Baibulo lachikale lopangidwa kuti ligwirizane ndi zigawo ziwiri za mapaipi amtundu womwewo;

• chigongono - chinthu chozungulira cha payipi chokhala ndi m'mphepete mwapadera chomwe chimalola kukhazikitsa kosavuta kwa clamp;

• mapulagi - zigawo zomwe zimakulolani kuti mutseke kwakanthawi kapena kosatha nthambi yamapaipi kapena kutsimikizira kugwirizana kwa groovelock ndi ulusi;

• ma adapter concentric - amakulolani kuti mugwirizane ndi chitoliro chaching'ono chochepa chokhala ndi ulusi wokhazikika;

• slip-on flange - imatsimikizira kusintha kwa dongosolo la groove ku dongosolo la flange;

• zowonjezera zina - zitsanzo zambiri zimapangidwira kupanga ma bends osakanikirana mwachindunji pamagulu.

Pali zomangira zolimba komanso zosinthika grooved. Oyamba awonjezera mphamvu zofananira ndi weld. Zosankha zosinthika zimakulolani kuti muthe kulipira zopatuka zazing'ono ndikupirira kupsinjika kwa mzere ndi kukangana. Zomangamanga zimagwiritsidwa ntchito pamapaipi okhala ndi mainchesi 25-300 mm, kotero ndizosavuta kusankha zingwe zamapaipi pazolinga zosiyanasiyana. Pogula zopangira, m'pofunika kufotokozera mitundu yosiyanasiyana ya ma diameter omwe chinthucho chimapangidwira. Izi zidzakuthandizani kudziwa ngati njira ina ili yoyenera kwa inu.
