Ni iki CV (umuvuduko w'amazi) ya valves z'isi?

Ni iki gipimo cy'umuvuduko w'ingufu z'isi (globe valve)?

Igipimo cy'umuvuduko w'amazi (agaciro ka Cv) k'umuvuduko w'amazi akenshi kiba kiri hagati ya make na mirongo, kandi agaciro kabyo gatandukana bitewe n'umurambararo w'umuvuduko w'amazi, imiterere, ubwoko bw'inkingi ya valve, ibikoresho by'intebe ya valve ndetse n'uburyo ikorwa neza. Ibi bikurikira ni bimwe mu bipimo biteganijwe mu bihe bisanzwe:

1. Hakurikijwe umurambararo w'amazina

Valve nto y'umurambararo w'isi: Agaciro ka Cv k'umugozi muto w'umubumbe ufite umurambararo hagati ya santimetero 1.5 (DN15) na santimetero 2 (DN50) muri rusange kari hagati ya 2.5 na 20. Urugero, agaciro ka Cv k'umugozi w'umubumbe wa santimetero 1.5 (DN15) gashobora kuba hagati ya 2.5 na 4, agaciro ka Cv k'umugozi w'umubumbe wa santimetero 1 (DN25) kakaba hagati ya 6 na 10, naho agaciro ka Cv k'umugozi w'umubumbe wa santimetero 2 (DN50) gashobora kuba hagati ya 12 na 20.

Valve y'umubumbe w'ubugari buri hagati: Ku balve z'umurambararo uringaniye zifite umurambararo wa santimetero 2.5 (DN65) kugeza kuri santimetero 6 (DN150), agaciro ka Cv gakunze kuba hagati ya 20 na 60. Urugero, agaciro ka Cv ka balve y'umurambararo ya santimetero 2.5 (DN65) gashobora kuba hagati ya 20 na 30, agaciro ka Cv ka balve y'umurambararo ya santimetero 4 (DN100) gashobora kuba hagati ya 35 na 50, naho agaciro ka Cv ka balve y'umurambararo ya santimetero 6 (DN150) gashobora kuba hagati ya 45 na 60.

Valve nini y'umurambararo w'isi: Vali nini z'umurambararo w'isi zifite umurambararo urenze santimetero 6 (DN150) zifite agaciro ka Cv kanini, muri rusange kari hejuru ya 60 kugeza 100. Urugero, agaciro ka Cv k'ivali y'umurambararo w'isi ya santimetero 8 (DN200) gashobora kuba hagati ya 80 na 100, naho agaciro ka Cv k'ivali y'umurambararo w'isi ya santimetero 12 (DN300) gashobora kuba hagati ya 120 na 150 cyangwa birenga.

2. Ku bijyanye n'imiterere y'imiterere

Valve inyura mu mubumbe igororotse: Agaciro ka Cv kari hejuru cyane, muri rusange kari ku rwego rwo hagati y’utubumbe tw’isi dufite umurambararo umwe. Urugero, agaciro ka Cv ka valvu ya DN50 igororotse inyura mu isi ni hagati ya 10 na 15, naho agaciro ka Cv ka valvu ya DN100 igororotse inyura mu isi ishobora kuba hagati ya 30 na 40.

Valve y'umubumbe w'inguni: Kubera ko inzira yayo yo gutemberamo ihindagurika cyane kandi ubushobozi bwo guhangana n'amazi bukaba bunini, agaciro ka Cv kari hasi gato ugereranyije n'ak'agace k'isi gahagaze neza. Agaciro ka Cv k'agace k'isi gafite angle ya DN50 gashobora kuba hagati ya 8 na 12, naho agaciro ka Cv k'agace k'isi gafite angle ya DN100 kakaba hagati ya 25 na 35.

3. Ukurikije ubwoko bw'inkingi ya valve

Valve y'umubumbe w'imbere w'ikirahure cy'igorofa: Agaciro ka Cv kari hejuru cyane, urugero, agaciro ka Cv ka valve ya DN100 flat valve core globe valve gashobora kuba hagati ya 40 na 50.

Valve y'ibanze y'umubumbe w'impande y'umubiri ifite imiterere y'inyuguti y'urukiramende: Bitewe n'uko igice cy'imbere cya valve n'intebe ya valve bikorana cyane, ubushobozi bwo gufunga burushaho kuba bwiza, ariko ubushobozi bwo kwirinda amazi ni bwinshi, kandi agaciro ka Cv ni gato. Agaciro ka Cv ka valve ya DN100 conical valve core globe valve gashobora kuba hagati ya 30 na 40.

4. Hakurikijwe ibikoresho by'intebe ya valve n'uburyo bwo kuyitunganya neza

Valve y'icyuma yo kwicaraho umubumbe w'intebe: Intebe y'icyuma ifite ubukana bwinshi kandi idashobora kwangirika neza, ariko ibisabwa mu gutunganya neza ni byinshi. Iyo uburyo bwo gutunganya neza ari bwinshi, agaciro ka Cv gashobora kugera ku rwego rwo hejuru rw'ubwoko bumwe bwa valve; niba uburyo bwo gutunganya neza budahagije, ubuso bwo gufunga bushobora kuba butangana kandi agaciro ka Cv kakagabanuka. Urugero, agaciro ka Cv ka valve y'icyuma ya DN80 ifite uburyo bwo gutunganya neza cyane gashobora kuba hagati ya 30 na 35, kandi agaciro ka Cv k'uburyo bwo gutunganya neza rusange gashobora kuba hagati ya 25 na 30.

Valve yoroshye yo kwicaraho ikoresha icyuma gikingira umugozi: Iyo ibikoresho byoroshye nka polytetrafluoroethylene bikoreshejwe nk'intebe z'abafunga, imikorere yo kuzifunga iba myiza, ariko ibikoresho byoroshye bishobora kwangirika bitewe n'ubushyuhe bwinshi cyangwa umuvuduko mwinshi, bigahindura ingano y'amazi anyuramo. Valve yoroshye ya DN65 ishobora kugira agaciro ka Cv kari hagati ya 20 na 25.

Incamake

Valve y'umubumbe ni igikoresho cy'ingenzi cyo kugenzura ubwiyongere bw'amazi. Igipimo cy'ubwiyongere bw'amazi ni ingenzi gisobanura ubushobozi bwayo bwo gutembera kandi kigomba kubarwa no gutoranywa mu buryo bukwiye. Gusobanukirwa ibintu bigira ingaruka ku gipimo cy'ubwiyongere bw'amazi bishobora gufasha guhitamo valve y'umubumbe ikwiye kugira ngo sisitemu ikore neza.
