Kusanthula ndi Kuchiza kwa Kutuluka Kwamkati ndi Kutuluka Kwakunja kwa Cryogenic Valves

1. Kutuluka kwamkati kwa vavu ya cryogenic:

Kusanthula:Kutuluka kwamkati kwa valve yotsika kutentha kumayambitsidwa makamaka ndi kuvala kapena kusinthika kwa mphete yosindikiza.Panthawi yoyeserera ntchitoyo, pali zonyansa zazing'ono monga mchenga ndi kuwotcherera slag mu payipi, zomwe zingayambitse kuvala kwa valve yosindikiza pamwamba pomwe valavu imatsegulidwa kapena kutsekedwa.

Chithandizo:Valavu ikafika pamalopo kuti iyesedwe ndikuyika, madzi otsalira ndi zonyansa m'thupi la valve ziyenera kutsukidwa.Chifukwa chake, njira zokonzetsera pamalopo zoperekedwa ndi wopanga komanso zinthu zomwe zimafunikira chidwi pakuyesa kwapamalo ziyenera kuphatikizidwa panthawi yomanga.Kudziwitsani malo ndi mosamalitsa kulamulira khalidwe kuti atsogolere kupanga, ntchito ndi kukonza polojekiti m'tsogolo.

2. Kutayikira kwa vavu ya cryogenic:

Kusanthula:Zifukwa za kutayikira kwa mavavu a cryogenic zitha kugawidwa m'zifukwa zinayi izi:

1. Ubwino wa valavu palokha siwokwanira, ndi matuza kapena ming'alu ya zipolopolo;

2. Panthawi yopangira, pamene valavu imagwirizanitsidwa ndi flange yomwe imagwiritsidwa ntchito popanga payipi, chifukwa cha zipangizo zosiyanasiyana zazitsulo zogwirizanitsa ndi gaskets, mutalowa mkatikati mu payipi, m'malo otsika kutentha, zipangizo zosiyanasiyana zimachepa mosiyana. , kumabweretsa kumasuka;

3. Njira yoyika ndi yolakwika;

4. Kutayikira pa tsinde la valve ndi kulongedza.

 The processing njira ndi motere:

1. Chidziwitso cha dongosolo chisanaperekedwe, zojambula ndi zojambula zomwe zimaperekedwa ndi wopanga ziyenera kutsimikiziridwa ndi kutsirizidwa mu nthawi yake, ndipo woyang'anira fakitale ayenera kulankhulana ndi nthawi.Zopangira zomwe zikubwera ziyenera kuwunikiridwa mosamalitsa, ndipo RT, UT, PT ziyenera kuchitidwa molingana ndi zofunikira zaukadaulo.kuyendera, ndi kupanga lipoti lolembedwa.Perekani ndondomeko yatsatanetsatane yopangira.M'tsogolomu kupanga, ngati palibe zochitika zapadera, kupanga kuyenera kuchitidwa mosamalitsa malinga ndi ndondomeko yomwe ili ndi khalidwe lotsimikizika ndi kuchuluka kwake, ndipo ntchito yowunika iyenera kuchitidwa musanachoke ku fakitale.

2. Valavu yolembedwa ndi njira yoyendetsera iyenera kumvetsera chizindikiro cha kayendedwe ka kayendedwe ka valve thupi.Kuonjezerapo: Kwa ndondomekoyi, ndikofunika kwambiri kulamulira nthawi yoyamba kuzizira kwa valve kuti valavu ikhale yokhazikika kwathunthu.Ndikofunikira kuyang'ana pafupipafupi ngati khoma lamkati la valavu lili ndi ming'alu, mapindikidwe ndi dzimbiri lakunja, makamaka kutentha kochepa.Valve ya sing'anga ndiyosavuta kukulitsa kutentha komanso kutsika.Kwa valavu pansi pa zovuta monga cavitation, m'pofunika kuonetsetsa mphamvu yake yopondereza, kutentha kochepa komanso kuvala kukana.
