Kutheni le valve yebhabhathane lingaqhelekanga kucavwe?

Ukuchaphazeleka kweI-Butterfly ValvesKubuqululi olunxulumene ngokusondeleyo kwiimpawu zabo zesakhiwo, iimpawu ze-fynamics zezahlulo, kunye neemeko zokusebenza. Izizathu ezizodwa zezi zilandelayo:

1. Ubume bebutetricly vallve kukhokelela ekusekweni kweendawo ezinoxinzelelo eziphantsi

Amacandelo okuvula kunye nokuvala kwiivali zebhabhathane ziipleyiti ezenziwe ngebhabhathane. Xa ijikeleza ivulekile, i-fluid kufuneka ihambe ecaleni kweplate yebhabhathane. Indawo yoxinzelelo esezantsi yendawo iya kwenza emva kweplate yebhabhathane (icala elikhathini). Xa uxinzelelo lwe-fluid luyehla ngaphantsi koxinzelelo lwe-vapor olugxunyekileyo, iigesi ezichithwe kulwelo ziya kuthi zichaneke kwaye zenze iqonga, eliyinqanaba lokuqala le-cavition.

Imeko eqhelekileyo: phantsi koxinzelelo oluphezulu okanye iimeko ezihamba ngesantya esiphezulu, i-velocity yesantya esiphezulu, i-velocity yendawo yokuhamba kwamanzi emphethweni yeplanethi yebhabhathane yonyuka kakhulu. Ngokutsho komgaqo kaBernoulili, ukwanda kwe-velocity freecity kukhokelela ekuncipheni koxinzelelo, ukwandisa ngakumbi ukwandisa iindawo zoxinzelelo oluphantsi kunye nokudala iimeko zoCavity.

2. Ifuthe le-Uning Subbulence kunye neBubble iwa

Xa ulwelo lukhathaza amaqamza kwindawo yoxinzelelo oluphezulu (njengokudlala ezantsi kweI-Butterfly Valves), Iibhubhu ziya kuwa ngokukhawuleza, zivelise ijeets ezincinci ezinefuthe kumphezulu wensimbi. I-frequency yeli mpembelelo iphakame kakhulu (ukuya kuthi ga kumashumi amawaka amaxesha), kubangela ukuba kuchithe kancinci kancinci kwaye kubeyonakalisa umphezulu wensimbi.

Inkxaso yedatha: Iimvavanyo zibonakalisile ukuba amandla empembelelo eziveliswe yi-Bubble Wish inokuthi ifikelele kwi-megascals enama-megapascals ezilikhulu, kude kakhulu kumandla okudinwa izixhobo zentsimbi, kwaye yindlela ephambili yomonakalo we-cavitity.

I-3. Iimpawu ezilawulayo zamabhabhathane ziyandisa umngcipheko wokopisha

I-valves zebhabhathane zihlala zisetyenziselwa umgaqo-nkqubo wokuhamba, kodwa xa i-valve incinci (<15 °), i-fluid ihamba ngomngxunya phakathi kweplate yebhabhathane, inciphisa i-vandocity velocity, kwaye inyuse ingozi ye-cavite.

Ityala lobunjineli: Kwindawo yokunyanga i-Inlet okanye inkqubo yokuhamba ye-Debage yeSikhululo se-HydroPower, ukuba ivalve yebhabhathane ikwimo yokuvula ixesha elide, ukuba imingxunya ye-caviticay iya kuvela ngokukhawuleza nangokungafikeleli kwi-vate ye valve okanye i-ring yokutsalela ipleyiti.

4. Impembelelo yeempawu eziphakathi kunye neemeko zokusebenza

Isuntswana eliqukethekileyo: Ukuba ulwelo luqukethe amasuntswana anzima njenge-sediment kunye ne-oxis yentsimbi eveliswe ngu-Caviticals, i-scovion ye "i-evvion" kunye nokukhawulezisa ukungaphumeleli.

Ubushushu obuphezulu okanye imidiya yobuthathaka: Ubushushu obuphezulu bunciphisa uxinzelelo lolwelo kwaye kukhuthaze ukusekwa kweebhubhu; Imithombo yeendaba ebomvu inokwenza buthathaka ubuchule bezinto zentsimbi, kwaye impembelelo kabini yandisa ukusilela kweevallo zebhabhathane.

5. Ukunqongophala kweentlobo zebhotolo zebhabhathane kunye noyilo

I-vaterve enye / yebhabhathane yebhabhathane: Kuyimfuneko ukuqwalasela ulwalathiso lokuhamba kwamanzi (iplate ye-valve ehamba phantsi). Ukufakelwa ngokubuyisela umva kuya konakalisa uzinzo lwendawo yokuhamba kunye nokwandisa umngcipheko wocaphu.

Ukufakwa kwepayipile ethe nkqo: Ubunzima be-valve bunokubangela uxinzelelo olungalinganiyo kumphezulu wokutywina, olunokubangelwa kukuncitshiswa kwendawo kunye nokuphembelela i-cavite.

I-vaterve ethambileyo etywiniweyo: I-Rubber yokutywina i-rings ixhaphake kukonakalisa kunye nomonakalo phantsi kwefuthe le-Cavide, ngelixa ilukhuniI-Butterfly Valves, nangona ixhathise ukukhukuliseka, zineendleko eziphezulu kunye nezicelo ezilinganiselweyo.
