Gulu ndi mfundo zogwirira ntchito za vavu ya butterfly

Pali mitundu yambiri ya mavavu agulugufe, ndipo pali njira zambiri zogawa.

1. Kugawa ndi mawonekedwe
(1)valavu ya butterfly yokhazikika; (2) valavu yagulugufe yokhala ndi eccentric; (3) kawiri-eccentric butterfly valve; (4) valavu yagulugufe yamitundu itatu

2. Gulu molingana ndi zinthu zosindikizira pamwamba
(1) Vavu yagulugufe yolimba
(2) Vavu yagulugufe yomata mwamphamvu yachitsulo. Kusindikizaku kumapangidwa ndi zitsulo zolimba mpaka zitsulo zolimba.

3. Kugawa ndi mawonekedwe osindikizidwa
(1) Vavu yagulugufe yomangika.
(2) Vavu yagulugufe yotsekera. Kuthamanga kwa chisindikizo kumapangidwa ndi chinthu chosindikizira chosindikizira pampando kapena mbale.
(3) Vavu yagulugufe yosindikizidwa yokha. The chisindikizo kukakamiza enieni basi kwaiye ndi sing'anga kuthamanga.

4. Kugawikana ndi kukakamizidwa kwa ntchito
(1) Vavu yagulugufe. Vavu yagulugufe yokhala ndi mphamvu yogwira ntchito yotsika kuposa mpweya wokhazikika.
(2) Vavu yagulugufe yotsika mphamvu. Vavu yagulugufe yokhala ndi kuthamanga mwadzina kwa PN≤1.6MPa.
(3) Vavu yagulugufe yapakatikati. Kuthamanga mwadzina PN ndi valavu ya butterfly ya 2.5∽6.4MPa.
(4) Vavu yagulugufe yothamanga kwambiri. Kuthamanga mwadzina PN ndi valavu ya butterfly ya 10.0∽80.OMpa.
(5) Vavu yagulugufe yothamanga kwambiri. Vavu yagulugufe yokhala ndi kuthamanga kwadzina PN <100MPa.

5. Gulu ndi njira yolumikizira
(1)Valve yagulugufe wawafer
(2) Valovu yagulugufe
(3) Vavu ya gulugufe
(4) Vavu yagulugufe yowotcherera

Vavu ya Gulugufe wa Concentric ndi mtundu wa valavu yomwe imatsegula ndi kutseka ndi mbale yagulugufe yozungulira ndikutsegula, kutseka ndi kusintha njira yamadzimadzi ndi kuzungulira kwa tsinde la valavu. Mbale yagulugufe ya valavu ya gulugufe imayikidwa m'mimba mwake ya chitoliro. Mu njira ya cylindrical ya thupi la butterfly valve, mbale ya butterfly ya disc imazungulira mozungulira, ndipo Angle yozungulira imakhala pakati pa 0 ndi 90. Pamene kuzungulira kukufika ku 90, valavu imatsegulidwa kwathunthu.

Mfundo zazikuluzikulu zomanga ndi kukhazikitsa
1) Malo oyika, kutalika, kulowetsa ndi kutumiza kunja kuyenera kukwaniritsa zofunikira za mapangidwe, ndipo kugwirizana kuyenera kukhala kolimba komanso kolimba.
2) Chogwirizira cha mitundu yonse ya mavavu amanja omwe amaikidwa pa chitoliro chotenthetsera kutentha sichiyenera kutsika.
3) Valve iyenera kuyang'aniridwa kunja musanayambe kuyika, ndipo dzina la valve liyenera kukwaniritsa zofunikira za "General Valve Mark" GB 12220. chitoliro, mphamvu ndi mayesero olimba a ntchito ayenera kuchitidwa asanakhazikitsidwe ndipo adzagwiritsidwa ntchito pambuyo pa oyenerera. Mu mayeso a mphamvu, kuthamanga kwa mayeso ndi nthawi 1.5 ya kukakamiza mwadzina, ndipo nthawiyo si yochepera 5min. Chigoba cha valve ndi kulongedza ziyenera kukhala zoyenerera popanda kutayikira. Pakuyesa kolimba, kuthamanga kwa mayeso ndi nthawi 1.1 ya kukakamiza mwadzina; kukakamizidwa kwa mayeso kudzakumana ndi muyezo wa GB 50243 panthawi yonse yoyezetsa, ndipo malo osindikizira a valve ndi oyenera.

Kusankha kwazinthu zofunikira
1. Zowongolera zazikulu za vavu ya gulugufe ndizofotokozera ndi miyeso.
2. Valve ya butterfly ndi valavu imodzi yamphepo yamphepo, mawonekedwe ake osavuta, kukonza kosavuta, mtengo wotsika, ntchito yosavuta, koma kulondola kwachindunji kumakhala kosauka, koyenera kokha kwa mpweya wabwino ndi makina opangira mpweya kuti asinthe kapena kusintha kwakukulu kwa chochitikacho.
3. Ikhoza kukhala ntchito yamanja, yamagetsi kapena yamtundu wa zipper, ikhoza kukhazikitsidwa pa Angle iliyonse ya 90.
4. Chifukwa cha mbale imodzi ya axial single valve, mphamvu yoberekera imakhala yochepa, mu chikhalidwe cha kusiyana kwakukulu, kuthamanga kwakukulu pamene moyo wautumiki wa valve uli waufupi. Valavu ili ndi mtundu wotsekedwa komanso mtundu wamba, kutsekereza komanso kusakhala ndi insulation.
5. Valavu yagulugufe yamagetsi imakhala ndi mitundu iwiri yokha yolamulira, magetsi oyendetsa magetsi ndi ofanana ndi valavu yamitundu yambiri.
