Ma valve a butterfly amagwiritsidwa ntchito kwambiri popereka madzi, kuyeretsa madzi oyipa, komanso kukonza mankhwala.Chifukwa ali ndi mapangidwe osavuta, amagwiritsa ntchito bwino zinthu, ndizochepa, komanso ndizotsika mtengo.
Kuyika ma valve moyenera kumatsimikizira kugwira ntchito bwino komanso moyo wautali.Musanakhazikitse valavu ya butterfly, ndondomeko ya kukhazikitsa iyenera kumveka.Pa unsembe, inu okondedwa ayeneranso kutsatira chitetezo.
1. Momwe mungayikitsire valavu ya butterfly pa chitoliro?
a)Zida zofunika
Kuyika vavu ya gulugufe kumafuna zida zosiyanasiyana zothandizira.
-Mawotchi amalimbitsa mabawuti.
-Mawotchi a torque amayang'ana ngati kuyikako kuli mkati mwa ma torque oyenera.
-Ma screwdriver amateteza tizigawo tating'ono.
-Odula mapaipi amapanga mipata yoyika ma valve a butterfly.
-Magolovesi oteteza chitetezo ndi magalasi amapewa zoopsa zomwe zingachitike.
-Mulingo ndi chingwe chowongolera: Onetsetsani kuti valavu ya gulugufe yayikidwa m'njira yoyenera.
b) Zida zofunika
-Zida zapadera zimafunikira pakuyika.
- Ma gaskets amasindikiza bwino valve ya butterfly ndi flange.
-Maboti ndi mtedza zimateteza valavu ya gulugufe ku chitoliro.
-Zinthu zoyeretsera zimachotsa zinyalala ku chitoliro ndi ma valve omwe amapangidwa pakukhazikitsa.
2. Njira Zokonzekera
Kuyang'ana Vavu ya Gulugufe
-Kuyendera valavu ya gulugufe musanayike ndi gawo lofunikira.Wopanga amayang'ana valavu iliyonse yagulugufe asanatumize.Komabe, mavuto angabwerebe.
-Yang'anani valavu yagulugufe kuti muwone kuwonongeka kapena kuwonongeka kulikonse.
-Onetsetsani kuti diski ya valve imazungulira momasuka ndipo siyimamatira.
- Onetsetsani kuti mpando wa valve ndi wokhazikika.
- Onani kuti kukula kwa valve ndi kuthamanga kwake kumagwirizana ndi zomwe payipi imayenera.
Konzani Mapaipi a Paipi
Kuyendera valavu ya gulugufe n'kofunika mofanana ndi kuyendera payipi.
- Tsukani payipi kuti muchotse dzimbiri, zinyalala ndi zowononga.
-Yang'anani momwe ma flanges olumikizira mapaipi amayendera.
-Onetsetsani kuti ma flanges ndi osalala komanso osalala opanda ma burrs.
-Tsimikizirani kuti payipi imatha kuthandizira kulemera kwa vavu ya gulugufe, makamaka kwa mavavu akulu.Ngati sichoncho, gwiritsani ntchito bulaketi yapadera.
3. Njira yoyika
a) Kuyika Vavu ya Gulugufe
Ikani valavu ya gulugufe moyenera mu payipi.
Disiki ya valve imatsegulidwa pang'ono kuti isawononge kapena mpando pamene ikufinya.Ngati ndi kotheka, gwiritsani ntchito flange yapadera yopangidwira mavavu agulugufe amtundu wa wafer.Disiki ya valavu imatseguka pang'ono kuti isawononge valavu ya valavu kapena mpando wa valve pamene ikufinya mpando wa valve.
Yang'anani kolowera
Onetsetsani kuti valavu yagulugufe yayikidwa molunjika.
Mavavu agulugufe wapakati nthawi zambiri amakhala ma valve agulugufe amitundu iwiri.Mavavu agulugufe a Eccentric nthawi zambiri amakhala osagwirizana pokhapokha ngati pangafunike. Njira yoyendera ya sing'anga iyenera kufanana ndi muvi womwe uli pa thupi la valavu, kuti zitsimikizire kusindikiza kwa mpando wa valve.
Kukonza valavu ya butterfly
Ikani mabawuti kudzera m'mabowo agulugufe ndi payipi.Onetsetsani kuti valavu ya gulugufe yatuluka ndi payipi.Kenako, amangitsa iwo mofanana.
Kumangitsa mabawuti mu nyenyezi kapena nyenyezi yamtanda (ndiko kuti, diagonal) kumatha kugawanitsa kukakamiza.
Gwiritsani ntchito wrench ya torque kuti mufikire torque yomwe mwatchula pa bawuti iliyonse.
Pewani kuwonjezereka, mwinamwake kuwononga valavu kapena flange.
Lumikizani chipangizo chothandizira cha actuator
Lumikizani magetsi kumutu wamagetsi.Komanso, gwirizanitsani mpweya kumutu wa pneumatic.
Zindikirani: The actuator yokha (chogwirira, giya la nyongolotsi, mutu wamagetsi, mutu wa pneumatic) wasinthidwa ndikusinthidwa kuti valavu yagulugufe isatumizidwe.
Kuyendera komaliza
-Yang'anani ngati chisindikizo cha agulugufe ndi mapaipi ali ndi zizindikiro zosokoneza kapena kuwonongeka.
- Onetsetsani kuti valavu ikuyenda bwino potsegula ndi kutseka valavu kangapo.Kaya diski ya valve imatha kuzungulira momasuka popanda chopinga chilichonse kapena kukana kwambiri.
-Yang'anani malo onse olumikizirana ndi kutayikira.Mutha kuyesa kutayikira pokakamiza mapaipi onse.
-Pangani zosintha zilizonse zofunika kuti muwonetsetse kuti zikuyenda bwino.
Kuthetsa Mavuto Odziwika
Vavu yagulugufe sitsegula kapena kutseka bwino: Yang'anani zinthu zomwe zatsekereza chitoliro.Komanso, yang'anani mphamvu yamagetsi a actuator ndi kuthamanga kwa mpweya.
Kuthira polumikizira: Onani ngati mbali yakutsogolo ya mapaipi ndi yosagwirizana.Komanso, onani ngati mabawuti ali olimba mosagwirizana kapena omasuka.
Kuyika ndi kukonza moyenera kumatsimikizira kuti valavu ya butterfly imagwira ntchito bwino m'njira zosiyanasiyana.Kuyika kwa valve ya butterfly kumaphatikizapo njira zingapo zofunika.Kuyeretsa musanakhazikitse, kuyanjanitsa koyenera, kukonza ndi kuyang'anitsitsa komaliza kumatsimikizira ntchito yabwino.Phunzirani mosamala ndikutsatira izi musanayambe kukhazikitsa.Kuchita zimenezi kungathandize kupewa mavuto ndi ngozi.
Kupatula apo, pali mwambi wakale wachi China woti, “kunola mpeni sikuchedwetsa kudula nkhuni.”
