I-Double Orifice Air Release Valve

Mayelana ne-Double Orifice Air Release Valve:

I-valve yokukhishwa komoya eyi-double orifice uhlobo lwevalvu esetshenziswa kumapayipi ukukhulula umoya namanye amagesi angase anqwabelene ohlelweni.Inama-orifice amabili, eyokukhulula umoya kanye neyokukhulula i-vacuum.I-vacuum orifice isetshenziselwa ukukhulula umoya epayipini lapho igcwele amanzi, kuyilapho i-vacuum ephumayo isetshenziselwa ukuvumela umoya ukuthi ungene epayipini lapho kunesikhala esidalwe ngenxa yokugeleza kwamanzi noma ezinye izici.Le valve isiza ukuvimbela ukulimala kwepayipi ngokugcina ukucindezela okufanele nokuvimbela amaphakethe omoya ukuthi akheke.

I-valve yomoya eyi-double orifice ehlanganisa kokubili ukusebenza kwe-orifice enkulu kanye ne-orifice encane ngaphakathi kweyunithi eyodwa. I-orifice enkulu ivumela umoya ukuthi ukhishwe ohlelweni ngesikhathi sokugcwaliswa kwepayipi futhi ibuyisele umoya ohlelweni noma nini lapho kuba khona ukucindezela komkhathi ongaphansi. Umoya uyakhishwa. kusuka ohlelweni kuze kube yilapho amanzi engena ku-valve bese ephakamisa ukuntanta esihlalweni sayo, eqinisekisa uphawu oluqinile. Uma kwenzeka kuba nomfutho we-sub-atmospheric ohlelweni, izinga lamanzi liyehla libangele ukuba i-float iwe esihlalweni sayo futhi ivumele ukungena umoya.

Ngesikhathi sokusebenza okujwayelekile kwe-main imbobo encane ikhipha umoya onqwabelana ngaphansi kwengcindezi.Nge-main esebenzayo, iflothi ngokuvamile iphikisana nesihlalo sayo. Njengoba umoya ungena emzimbeni wegumbi izinga lamanzi liyacindezeleka kuze kube yilapho kufinyelelwa izinga lapho ukuntanta kutholakala khona. amaconsi enza isihlalo sawo, ovumela umoya ukuba uphume.Ukukhuphuka kwezinga lamanzi okulandelanayo kubuyisela ukuntanta esihlalweni sayo.

I-ductile iron double orifice air release valve iwuhlobo lwevalvu esetshenziswa ezinhlelweni zokusabalalisa amanzi ukukhulula umoya epayipini.Iklanyelwe ukuvimbela amaphakethe omoya ukuthi angakheki epayipini, okungadala izinkinga ezifana nokuncishiswa kokugeleza, ukwanda komfutho, kanye nokulimala kwepayipi.

I-valve yenziwe nge-ductile iron, okuwuhlobo lwe-cast iron eguquguqukayo futhi ehlala isikhathi eside kune-cast iron yendabuko.Lokhu kwenza ukuthi imelane kakhulu nokuqhekeka nokuphuka ngaphansi kwengcindezi, okubalulekile ezinhlelweni zokusabalalisa amanzi.

Idizayini ye-valve eyi-double orifice ivumela ukuthi umoya uphume kokubili phezulu nangaphansi kwevalvu, okusiza ukuqinisekisa ukuthi wonke amaphakethe omoya ayakhishwa epayipini.Lokhu kusiza ukugcina ukugeleza kwamanzi okungaguquki futhi kuvimbele ukulimala epayipini.

Sekukonke, i-ductile iron double orifice air release valve iyisici esibalulekile sezinhlelo zokusabalalisa amanzi, esiza ukuqinisekisa ukuthi amanzi alethwa ngendlela efanele futhi enokwethenjelwa kubathengi.
