Ithetha ukuthini ixabiso le-CV? Ungayikhetha njani i-valve yolawulo yixabiso le-CV?

InivalveUbunjineli, ixabiso le-CV (ukuhamba kwe-CV) yolawuloivalveIbhekisa kwiqondo lokuhamba kwevolumu okanye inqanaba lokuhamba kwesininzi lombhobho kwivali kwi-valve yexesha ngalinye kwaye phantsi kweemeko zovavanyo xa umbhobho ugcinwa kwingcinezelo engapheliyo. Oko kukuthi, umthambo wevali.

Ixabiso eliphezulu lokuhamba, iphantsi kwelahleko yoxinzelelo njengoko i-fluid ihamba ngeivalve.

Ixabiso le-CV le-CV kufuneka ligqitywe kuvavanyo kunye nokubalwa.

I-CVixabisoIparamitha ebaluleke kakhulu elinganisa ubungakanani bokuhamba kwe-valve yolawulo phantsi kweemeko ezithile. Ixabiso le-CV alibonisi kuphela intsebenzo yevalva, kodwa ikwanxulumene ngqo nokuyilwa nokusebenza kwempumelelo kwenkqubo yokulawula ulwelo.

Inkcazo ihlala isekwe kwezi meko ziqhelekileyo zilandelayo: Iivalveivulekile ngokupheleleyo, umahluko woxinzelelo yi-1 lb / in² (okanye i-7KPA) kwiziphelo, kwaye i-fluid i-60 ° F) i-sleid (i-15.6 ° 2 Kufuneka kuqatshelwe ukuba ukuhamba okusebenzayo e-China kudla ngokuchazwa kwinkqubo yemeriri, kunye nophawu lwe-kv, kunye nobudlelwane nexabiso le-CV = 1.156K.

Ungalufumana njani ukufumanisa i-caliber yevali ngexabiso le-CV

1. Bala ixabiso le-CV elifunayo:

Ngokweemfuno ezithile zenkqubo yokulawula i-fluid, njengokuhamba, uxinzelelo ngokwahlukileyo, eliphakathi kunye nezinye iimeko, ixabiso le-CV libalwa lisebenzisa ifomula okanye isoftware efunekayo. Eli nyathelo lithathe inxaxheba kwi-akhawunti efana nepropathi yomzimba ye-fluid (umz.

2. Khetha ububanzi be-vialve efanelekileyo:

Ngokwexabiso le-CV ebaliweyo kunye nexabiso le-CV elinqatyisiweyo le-valve, i-vall ye-valve efanelekileyo ikhethiwe. Ixabiso le-CV elilinganayo le-valve ekhethiweyo kufuneka lilingane okanye likhulu elincinci kunexabiso le-CV lokuqinisekisa ukuba ivalve inokuqinisekisa ukuba ivalve inokudibana nemfuno yokwenyani. Kwangelo xesha, kuyimfuneko ukuqwalasela ezinye izinto ezinjengesona sixhobo, ukuma, intsebenzo yokutywina, imowudi yokusebenza yevali yokuqinisekisa ukuba intsebenzo iyonke ihlangabezana neemfuno ze-vali.

3. Ukuqinisekiswa kunye nohlengahlengiso:

Emva kokhetho lokuqala lweivalveI-caliber, ukuqinisekiswa okufanelekileyo kunye nohlengahlengiso kufuneka lwenziwe. Oku kubandakanya ukuqinisekisa ukuba ukusebenza kwe-valve kuhlangabezana neemfuno zenkqubo ngokulwa kwezinto okanye ukuvavanywa kwehlabathi. Ukuba kuphambuka kuphambuka okukhulu, kunokuba yimfuneko ukuphinda ixabiseke ixabiso le-CV okanye uhlengahlengise ububanzi be-vove.

Isishwankathelo

Kwinkqubo yokubonelela ngamanzi ngesakhiwo, ukuba i-valve yokulawula ayifikeleli kwixabiso le-CV efunekayo, impompo yamanzi inokuqalisa kwaye iyeke rhoqo okanye ibaleke kumthwalo ophezulu ngalo lonke ixesha. Ayisiyiyo kuphela le nkcitho yamandla ombane, kodwa ngenxa yoxinzelelo oluqhubekayo, lunokukhokelela kunxibelelwano oluqhutywa ngumbhobho, kuvuza, kwaye kunokubangela ukonakala kwi-pump ngenxa yokulayisha kakhulu.

Isishwankathelo, ixabiso le-CV le-valve yokulawula sisikhombisi esibalulekileyo ukulinganisa umthamo wayo wokuhamba. Ngokubala ngokuchanekileyo ixabiso le-CV kunye nokumisela i-caliber efanelekileyo esekwe kuyo, uzinzo kunye nokusebenza kwenkqubo ye-fluid kunokuqinisekiswa. Ke ngoko, kwinkqubo yokukhetha iveli, uyilo lwenkqubo kunye nolungelelwaniso lwenkqubo, ingqalelo epheleleyo kufuneka ihlawulwe kubalo kunye nokusetyenziswa kwexabiso le-CV.
