3. Globe, valavu ya globe

Tsinde la valve limayendetsa valavu yotsegula ndi kutseka (disc), yomwe imayenda mmwamba ndi pansi pamphepete mwa mpando wa valve (kusindikiza pamwamba).

4. Kusintha kwamphamvu

valavu yomwe imasintha kuyenda ndi kupanikizika mwa kusintha malo odutsa njirayo kupyolera mu gawo lotsegula ndi lotseka (disc).

5. Valve ya mpira

valavu ya mpira yomwe ndi valavu yozimitsa ndipo imazungulira m'mbali mwake molingana ndi ndimeyo.

6. Valve ya butterfly

imatsegula ndi kutseka valavu yomwe imazungulira mozungulira (valavu ya "gulugufe").

7. Vavu ya diaphragm (valavu ya diaphragm)

Kupatula njira yochitira zinthu kuchokera pakatikati, mtundu wotsegulira ndi kutseka (mtundu wa diaphragm) umayenda mmwamba ndi pansi motsatira tsinde la valavu.

8. Tambala kapena valavu ya pulagi

valavu ya tambala yomwe imatha kuyatsidwa ndikuzimitsa.

9. (Chongani valavu, valavu)

Mtundu wotseguka (dimba) umagwiritsa ntchito mphamvu ya sing'anga kuti ingoyimitsa sing'angayo kuti isayende mbali ina.

10. Vavu yachitetezo (yomwe nthawi zina imatchedwa valavu yopumira kapena valavu yotetezera)

Mtundu wa diski yotseguka Kuti muteteze payipi kapena makina, kupanikizika kwapakatikati pazidazo kumangotsegula ndikutulutsa pamene kupitirira mtengo wotchulidwa ndikutseka pokhapokha ngati kugwera pansi pa mtengo wotchulidwa.

11. Chida chotsitsa mphamvu

Kuthamanga kwa sing'anga kumachepetsedwa ndikugwedeza magawo otsegulira ndi kutseka (disc), ndipo kupanikizika kumbuyo kwa valve kumasungidwa mwachisawawa ndi zomwe zimapangidwira kumbuyo kwa valve.

12. Msampha wa nthunzi

valavu yomwe imalepheretsa nthunzi kuthawa pamene imangotulutsa condensate.

13. Vavu yokhetsa

ma valve omwe amagwiritsidwa ntchito muzotengera zokakamiza ndi ma boilers kuti azitaya zimbudzi.

14. Kusinthana kwapansi kochepa

mavavu osiyanasiyana ndi PN1.6MPa kuthamanga mwadzina.

15. Valavu yapakatikati

Mavavu osiyanasiyana okhala ndi kuthamanga kwadzina PN≥2.0～PN＜10.0MPa.

16. Kusinthana kwakukulu

mavavu osiyanasiyana okhala ndi kuthamanga kwa PN10.0MPa mwadzina.

17. Valavu yothamanga kwambiri

mavavu osiyanasiyana ndi PN 100.0 MPa mphamvu mwadzina.

18. Kusintha kwa kutentha kwapamwamba

amagwiritsidwa ntchito pamitundu yosiyanasiyana ya mavavu okhala ndi kutentha kwapakati kuposa 450 ° C.

19. Vavu yapansi-zero (valavu ya cryogenic)

mavavu osiyanasiyana kwa sing'anga kutentha osiyanasiyana -40 kuti -100 madigiri Celsius.

20. Vavu ya cryogenic

Oyenera kutentha kwapakati mavavu amitundu yonse ndi kutentha kwa -100 ° C.
