Magulu 6 a ma valve agulugufe osindikizira

Monga chigawo chomwe chimagwiritsidwa ntchito pozindikira kuwongolera ndi kuyendetsa kayendedwe ka mapaipi, valavu ya butterfly yosindikizidwa yofewa yakhala ikugwiritsidwa ntchito kwambiri m'madera ambiri monga mafuta, makampani opanga mankhwala, zitsulo, hydropower ndi zina zotero.Disiki ya valavu yagulugufe yotseka yofewa imayikidwa molunjika papaipi.Mu cylindrical ndime ya gulugufe thupi valavu, mbale woboola pakati gulugufe mbale amazungulira mozungulira olamulira, ndi kasinthasintha ngodya ndi pakati 0 ° ndi 90 °.Ikazungulira mpaka 90 °, valavu imatsegulidwa kwathunthu.

1. Gulu mwa kusindikiza zinthu zapamwamba

1) Vavu yagulugufe yofewa yotsekera: Chosindikiziracho chimapangidwa ndi zinthu zofewa zopanda chitsulo kupita kuzinthu zofewa zopanda zitsulo.

2) Chitsulo cholimba chosindikizira agulugufe: Chosindikiziracho chimapangidwa ndi zitsulo zolimba mpaka zitsulo zolimba.

2. Kugawa ndi kamangidwe

1) valavu yagulugufe yosindikizira pakati

2) Valavu imodzi yokha yagulugufe yosindikiza

3) Vavu yagulugufe yosindikiza kawiri

4) Vavu yagulugufe yosindikiza katatu

3. Gulu mwa kusindikiza mawonekedwe

1) Vavu yagulugufe yokakamiza yosindikiza: Kusindikiza kumapangidwa ndi mbale ya valve ikanikiza mpando wa valve pamene valavu yatsekedwa, ndi kusungunuka kwa mpando wa valve kapena mbale ya valve.

2) Vavu yagulugufe yogwiritsidwa ntchito ndi torque: kusindikiza kumapangidwa ndi torque yomwe imagwiritsidwa ntchito pa shaft ya valve.

3) Vavu yagulugufe yosindikizira mopanikizika: Kusindikiza kumapangidwa ndi kulipiritsa chinthu chosindikizira chosindikizira pampando wa valve kapena mbale ya valve.

4) Valavu yagulugufe yosindikiza yokha: kusindikiza kumangopangidwa ndi mphamvu yapakatikati.

4. Kugawikana ndi kukakamizidwa kwa ntchito

1) Valavu yagulugufe: Vavu yagulugufe yomwe mphamvu yake yogwira ntchito ndiyotsika kuposa kuthamanga kwa mlengalenga.

2) Valavu yagulugufe yotsika: valavu yagulugufe yokhala ndi mphamvu yadzina PN <1.6MPa.

3) Vavu yagulugufe yapakatikati: valavu yagulugufe yokhala ndi mphamvu yadzina PN ya 2.5 mpaka 6.4MPa.

4) Vavu yagulugufe yothamanga kwambiri: valavu yagulugufe yokhala ndi mphamvu yadzina PN ya 10.0 mpaka 80.0MPa.

5) Vavu yagulugufe yothamanga kwambiri: valavu yagulugufe yokhala ndi mphamvu mwadzina PN> 100MPa.

5. Gulu ndi njira yolumikizira

1) Valve yagulugufe wawafer

2) Valve ya butterfly ya Flanged

3) Valavu ya butterfly

4) Wowotcherera agulugufe valavu

6. Gulu ndi kutentha kwa ntchito

1) Kutentha kwakukulu kwa gulugufe: > 450 ℃

2) Kutentha kwapakati pagulugufe valavu: 120 ℃

3) Normal kutentha gulugufe vavu: -40 ℃

4) Low kutentha gulugufe vavu: -100 ℃

5) Vavu yagulugufe yotsika kwambiri kutentha: <-100 ℃
