Kodi CV mtengo wa valve ndi chiyani?

Mtengo wa CV ndi mawu achingerezi Circulation Volume

Chidule cha voliyumu yothamanga ndi coefficient yotuluka idachokera ku tanthauzo la valve flow coefficient mu gawo la control engineering ku West.

Kuthamanga kwapakati kumayimira mphamvu yothamanga ya chinthucho kupita kukatikati, makamaka kwa valavu, ndiko kuti, kuthamanga kwa voliyumu (kapena kutuluka kwa misa) kwa sing'anga yamapaipi yomwe ikuyenda kudzera mu valavu pamene payipi imasunga kupanikizika kosalekeza mkati mwa nthawi imodzi. .

Ku China, mtengo wa KV nthawi zambiri umagwiritsidwa ntchito kuimira koyefithi yotaya, yomwe imakhalanso kuthamanga kwa voliyumu (kapena kutuluka kwa misa) ya sing'anga yamapaipi yomwe imayenda kudzera mu valve pamene payipi imasunga kupanikizika kosalekeza pa nthawi ya unit, chifukwa unit unit ndi gawo la voliyumu ndi losiyana.Pali ubale wotsatirawu: Cv =1.167Kv
