Khangela valve amanzi iindidi lwezilinganisi zokuzikhusela zabasebenzi njengogwali, ekuthi kujongwe ukuba ulwe utshintsho ukuhamba fluid kwicala reverse ngaphakathi kwinkqubo inkqubo. Ngokomzekelo, xa kwimeko yokusilela kwimpompo oko akuthethi ukuba amanzi ukuba kwicala elahlukileyo.
Khangela valve ngokuba amanzi intwasahlobo-ntli, ibhola, nesonkana esisicaba, emboxo, sembali. ufakelo yabo senziwe umbhobho nkqo okanye tye. ukusetyenziswa kwezi kwezi zixhobo zifumaneka kwiinkqubo lokuthathwa amaqula okanye igcwele impompo xa ufakelo kwenziwa elizimeleyo kwinkqubo yonikezelo. Kwakhona kubalulekile ukuba iinkqubo umjelo, njengoko kwimeko ukuvaleka na ukuthintela ukuhamba kwamanzi amdaka umva. Khangela valve ukuba amanzi abe iimpawu ezibalulekileyo kunye ezizodwa ezifana ezifana esebenza indlela nje kuphela ukusebenza eqhelekileyo kodwa likaxakeka.
Ukuba inkathazo yenzeka amanzi ngohlobo ukuvuza off iimpompo, zokucutha kwindawo ethile, ifowuni iya kuba ukhuseleko olusebenzayo ngokwaneleyo. Khangela ivelufa yamanzi, ixabiso elandelwayo exhomekeke izinto kungamampunge yahluka kwisithuba 300-1000 engange ilula ngendlela eyakhayo. Uyawavala ngokuzenzekelayo, ngokubonelela ngokomelela ukuhamba ukugeleza kwicala elahlukileyo. Ivelufa ezenziwa intsimbi, isinyithi waphosa, nobhedu kunye zeplastiki. Devices ezenziwa insimbi, aziwa umgangatho ophezulu kunye nokusebenza ophezulu.
Nesonkana esisicaba odnolepestkovy ngobuwena yohlukile uluhlu elikhulu iimeko lobushushu kunokwenzeka zokusingqongileyo, isantya yofakelo, ukuthembeka kunye nokusebenza ogqwesileyo uxinzelelo oluphezulu ezinosenokuthabatha kwi network. Ukuba yombhobho akukhange kubekho utshintsho indlela yokumpompoza, bhekisa ibhabhathane vana. Ezi zixhobo musa ukusebenzisa pads ngenxa yokuba umzimba ngokwawo lixhotyiswe ngamatywina ezongezelelweyo. Khangela valve ukuba amanzi abe eziluncedo ezininzi: ubunzima ukukhanya ubude, ngezinga eliphezulu lentembeko nokuthembeka, kwakunye kulula ukufaka.
Lo mgaqo uyasebenza kule hlobo lwesilinganisi elula kakhulu. Ukuba akukho koxinzelelo, kwaye izinga lokuhamba kwi conduit ngu zero, ngoko ke ilungu lokutshixa ukwimo closed. Oku kuphunyezwa ubunzima bayo okanye yasentwasahlobo ndingungelwe kuyo. Ukuba isantya sokuqukuqela ungaphezu zero, element isihlalo lokuvala ivula, nokuvumela intshukumo ulwelo xa edada. Xa flow iqala okanye eyeka intshukumo ukubuya, oko kwakudibana yi element, nto leyo licinezelwe nxamnye isihlalo vana. Reverse ivalve zamanzi zeplastiki isebenza kwi kumgaqo zonke ezinye iintlobo. Xa usebenzisa olu hlobo semigudu kuthathelwa ingqalelo ukuba ubunzima ilungu lokutshixa kunye nomkhosi spring ngamanye amaxesha kufuna uxinzelelo ngokugqithiseleyo ukuvula kuyo.
