Mfundo zosankhira ma valavu ndi njira zosankhira ma valavu

Mfundo yosankha mavavu
Valavu yosankhidwa iyenera kukwaniritsa mfundo zazikulu izi.
(1) Chitetezo ndi kudalirika kwa mafakitale a petrochemical, magetsi, zitsulo ndi mafakitale ena kumafuna kugwira ntchito kosalekeza, kokhazikika, komanso kwa nthawi yayitali. Chifukwa chake, valavu yofunikira iyenera kukhala yodalirika kwambiri, chitetezo chachikulu, sichingayambitse chitetezo chachikulu pakupanga ndi kuwonongeka kwa anthu chifukwa cha kulephera kwa valavu, kukwaniritsa zofunikira pakugwira ntchito kwa nthawi yayitali kwa chipangizocho, ndipo kupanga kosalekeza kwa nthawi yayitali ndiye phindu.
(2) Kuti akwaniritse zofunikira za valavu yopangira njira, ayenera kukwaniritsa zofunikira za sing'anga, kuthamanga kwa ntchito, kutentha kwa ntchito ndi zosowa zogwiritsira ntchito, zomwe ndizofunikira kwambiri pakusankha valavu. Ngati pakufunika chitetezo cha valavu chopondereza kwambiri, chotulutsa chowonjezera, ayenera kusankha valavu yotetezeka, chopondereza valavu yodzaza, ayenera kuletsa njira yogwirira ntchito ya sing'anga, ayenera kugwiritsa ntchito valavu yowunikira, ayenera kuchotsa chitoliro cha nthunzi ndi zida zina za condensate, mpweya ndi mpweya wopondereza womwe sungathe kupondereza, komanso kuti asatuluke nthunzi, ayenera kusankha valavu yopondereza. Kuphatikiza apo, ngati sing'angayo ili ndi dzimbiri, ayenera kusankha zipangizo zabwino zotsutsana ndi dzimbiri.

(3) Pambuyo pa ntchito, kukhazikitsa, kuyang'anira (kukonza) kukonza kwa valavu, woyendetsa ayenera kudziwa bwino komwe valavu ikupita, zizindikiro zotsegulira, zizindikiro zosonyeza, zosavuta kuzizindikira panthawi yake komanso moyenera kuthana ndi mavuto osiyanasiyana adzidzidzi. Nthawi yomweyo, kapangidwe ka mtundu wa valavu kosankhidwa kuyenera kukhala koyenera momwe zingathere, kuyika, kuyang'anira (kukonza) kukonza kosavuta.

(4) Zachuma Poganizira za kugwiritsa ntchito mapaipi amagetsi moyenera, ma valve okhala ndi mtengo wotsika wopanga komanso kapangidwe kosavuta ayenera kusankhidwa momwe angathere kuti achepetse mtengo wa chipangizocho, kupewa kuwononga zinthu zopangira ma valve ndikuchepetsa mtengo woyika ndi kukonza ma valve mtsogolo.

Masitepe osankha mavavu
Kusankha ma valve nthawi zambiri kumatsatira njira zotsatirazi:
1. Dziwani momwe valavu imagwirira ntchito malinga ndi momwe valavu imagwirira ntchito mu chipangizo kapena njira yopangira. Mwachitsanzo, malo ogwirira ntchito, kuthamanga kwa ntchito ndi kutentha kwa ntchito, ndi zina zotero.
2. Dziwani kuchuluka kwa magwiridwe antchito a valavu malinga ndi malo ogwirira ntchito, malo ogwirira ntchito komanso zofunikira kwa ogwiritsa ntchito.
3. Dziwani mtundu wa valavu ndi momwe imayendetsera malinga ndi cholinga cha valavu. Mitundu mongaValavu ya gulugufe yolimba, Valavu yolowera pa chipata chokhala ndi rabara,Valavu yokhazikika pa chipata cha mphira, valavu yolinganiza, ndi zina zotero. Njira yoyendetsera galimoto monga nyongolotsi ya gudumu la worm, yamagetsi, yoyendetsa mpweya, ndi zina zotero.
4. Sankhani malinga ndi magawo a valavu. Kupanikizika kwapadera ndi kukula kwa valavu kuyenera kufananizidwa ndi chitoliro choyendetsera ntchito chomwe chayikidwa. Vavu imayikidwa mu chitoliro choyendetsera ntchito, kotero momwe imagwirira ntchito iyenera kugwirizana ndi kapangidwe kake ka chitoliro choyendetsera ntchito. Pambuyo poti kupanikizika kwapadera kwa dongosolo ndi chitoliro kwatsimikizika, kupanikizika kwapadera kwa valavu, kukula kwapadera ndi kapangidwe ka valavu ndi miyezo yopangira zitha kudziwika. Mavavu ena amatsimikiza kukula kwapadera kwa valavu malinga ndi kuchuluka kwa madzi kapena kutulutsa kwa valavu panthawi yoyesedwa ya sing'anga.
5. Dziwani mawonekedwe olumikizira pamwamba pa valavu ndi chitolirocho malinga ndi momwe zimagwirira ntchito komanso kukula kwa valavuyo. Monga flange, welding, wafer kapena ulusi, ndi zina zotero.
6. Dziwani kapangidwe ndi mawonekedwe a valavu malinga ndi malo oikira, malo oikira, ndi kukula kwake kwa valavu. Monga valavu ya chipata chakuda, tsinde lokweravalavu ya chipata, valavu yokhazikika ya mpira, ndi zina zotero.
7. Malinga ndi makhalidwe a sing'anga, kuthamanga kwa ntchito ndi kutentha kwa ntchito, kuti musankhe bwino komanso moyenera valavu.
Ku Tianjin Tanggu Water Seal Valve Co., Ltd., timadzitamandira popereka zinthu zapamwamba kwambiri zomwe zimakwaniritsa miyezo yapamwamba kwambiri yamakampani. Ndi ma valve ndi zolumikizira zathu zosiyanasiyana, mutha kutidalira kuti tikupatseni yankho labwino kwambiri la makina anu amadzi. Lumikizanani nafe lero kuti mudziwe zambiri za zinthu zathu komanso momwe tingakuthandizireni.
