Kweli nqaku, siza kuhlola ukuba yintoni eyenza le valve ibe lukhetho olungcono kunye nesizathu sokuba isenokuba yinxalenye efanelekileyo yeprojekthi yakho elandelayo.
Yintoni iValve yeBhala yePort epheleleyo?
Inkcazo kunye neempawu eziphambili
Aivalvu yebhola yezibuko elipheleleyo, okwaziwa ngokuba yiivalvu yebhola epheleleyo, yenzelwe ibhola enkulu kakhulu ukuze umngxuma odlula ebholeni ("izibuko") ulingane nobubanzi bangaphakathi bombhobho odibanisayo. Olu yilo lunciphisa imida yokuhamba kwamanzi, luvumela ukuhamba kwamanzi okungathintelwanga kunye nokuhla koxinzelelo oluphantsi kakhulu kwivalvu. Olu luphawu oluphambili lokwahlula kwezinye iintlobo zeevalvu kwaye lubalulekile kwiindlela zokusebenza apho ukusebenza kakuhle kokuhamba kwamanzi kuyinto ephambili.
Uthelekiso neValve yeBhalbhu yePort esemgangathweni
Umahluko ophambili phakathi kwevalvu ye-port epheleleyo kunye ne-port eqhelekileyo ulele kubukhulu bebhola kunye nokuvulwa kwe-port okubangelwa yiyo. Ivalvu ye-port eqhelekileyo (okanye i-port encitshisiweyo) inebhola kunye ne-port encinci, nto leyo edala umda kwindlela yokuhamba. Oku kukhokelela ekwehleni koxinzelelo oluphezulu xa kuthelekiswa noyilo lwe-port epheleleyo. Nangona iivalvu ze-port eziqhelekileyo zincinci kwaye ngamanye amaxesha zingabizi kakhulu, azifanelekanga kwizicelo ezifuna umthamo ophezulu wokuhamba okanye apho kunokubakho imfuneko yokukhwela ihagu.
Iingenelo zeeValve zeBhalbhu eziPheleleyo
Amandla okuhamba okuphezulu
Eyona nzuzo ibalulekileyo yevalvu yebhola epheleleyo ye-port kukuba inamandla okuhamba kwamanzi aphezulu. Ngenxa yokuba ububanzi be-port buhambelana ne-ID yombhobho, ivumela ukuhamba kwamanzi okuphezulu kunye nokuxinana okuncinci kunye nokulahleka koxinzelelo. Oku kuyenza ifaneleke kwiinkqubo apho ukugcina isantya sokuhamba kwamanzi kunye noxinzelelo kubalulekile.
Iimpawu zokuPhucula eziphuculweyo
Uyilo lwangaphakathi lwevalvu egcweleyo lubonelela ngeempawu zokuhamba kwevalvu ezigqwesileyo. Ibonelela ngendlela yokuhamba ethe ngqo enciphisa ukungqubana kunye namathuba okubanjwa kwe-cavitation, nto leyo ekhokelela ekusebenzeni kakuhle kunye nokungonakali kakhulu kwevalvu kunye nemibhobho ekufutshane ngokuhamba kwexesha.
Ukuguquguquka kwizicelo
Iivalvu zebhola ezipheleleyo ze-port zinokuguquguquka okukhulu. Zisetyenziswa kumacandelo amaninzi, ukusuka kwioyile negesi ukuya ekucutshungulweni kweekhemikhali kunye nokucocwa kwamanzi. Uyilo lwazo luzenza zilungele ukuphatha izinto ezahlukeneyo, kuquka ulwelo, iigesi kunye ne-slurry.
Iimpawu Ezikhuselekileyo Emlilweni
Kwiizicelo ezifuna ukhuseleko oluphuculweyo, iivalvu ezininzi zebhola ezigcweleyo zenzelwe ukuba ziivalvu zebhola ezikhuselekileyo emlilweni. Ezi valve zakhiwe ngezitywino ezikhethekileyo kunye nezinto ezinokuqulatha imidiya kwaye zithintele ukuvuza kwangaphandle nokuba izitywino ezithambileyo zonakaliswe bubushushu obuphezulu obuvela emlilweni.
Iintlobo zeeValve zeBall zePort ezipheleleyo
Ukuguquguquka koyilo kuthetha ukuba kukho ivalvu yezibuko epheleleyo phantse kuzo zonke izicelo. Iindidi eziqhelekileyo ziquka:
