I-Cast Iron Ductile ye-Iron yoMoya yokuNceda iValve yeFlange yoPhelisa uMphefumlo waManzi kunye neVavalu yokukhupha iVacuum

Inkcazo:

Ivalve yokukhutshwa komoya edibeneyo enesantya esiphezulu idityaniswe kunye neenxalenye ezimbini zevalve yomoya we-diaphragm yoxinzelelo oluphezulu kunye ne-inlet yoxinzelelo oluphantsi kunye nevalve yokukhupha, Inemisebenzi yokukhupha kunye nokuthatha.
Ivalvu yokukhupha umoya we-diaphragm enoxinzelelo oluphezulu ikhupha ngokuzenzekelayo inani elincinci lomoya oqokelelene kumbhobho xa umbhobho uphantsi koxinzelelo.
I-valve ye-low-pressure intake kunye ne-valve yokukhupha ayikwazi ukukhupha umoya kuphela kwipayipi xa umbhobho ongenanto uzaliswe ngamanzi, kodwa naxa umbhobho ukhutshiwe okanye uxinzelelo olubi lwenzeka, njengaphantsi kwemeko yokwahlula ikholomu yamanzi, iya kuvula ngokuzenzekelayo kwaye ifake umbhobho ukuphelisa uxinzelelo olubi.

Iimfuno zokusebenza:

I-valve yokukhutshwa komoya ophantsi (i-float + uhlobo lwe-float) i-port yokukhupha i-port enkulu iqinisekisa ukuba umoya ungena kwaye uphuma kwizinga eliphezulu lokuhamba ngesantya esiphezulu sokuphuma komoya, kunye nesantya esiphezulu somoya esixutywe nenkungu yamanzi, ayiyi kuvala i-port yokukhupha kwangaphambili .I-port yomoya iya kuvalwa kuphela emva kokuba umoya ukhululwe ngokupheleleyo.
Ngaliphi na ixesha, ngokude nje uxinzelelo lwangaphakathi lwenkqubo lungaphantsi koxinzelelo lwe-atmospheric, umzekelo, xa ukuhlukana kwekholomu yamanzi kwenzeka, i-valve yomoya iya kuvula ngokukhawuleza emoyeni kwinkqubo yokukhusela ukuveliswa kwe-vacuum kwinkqubo. Kwangaxeshanye, ukungena komoya ngexesha elifanelekileyo xa isixokelelwano sikhupha isantya sinokukhawulezisa isantya sokukhupha. Umphezulu we-valve yokukhupha uxhotywe nge-plate echasayo ukuze ulungelelanise inkqubo yokukhupha, enokuthintela ukuguquguquka kwengcinezelo okanye ezinye izinto ezibhubhisayo.
I-valve yokukhupha i-high-pressure trace exhaust valve inokukhupha umoya oqokelelwe kwiindawo eziphakamileyo kwinkqubo ngexesha apho inkqubo iphantsi koxinzelelo ukuphepha izinto ezilandelayo ezinokubangela ingozi kwinkqubo: ukuvala umoya okanye ukuvala umoya.
Ukwandisa ukulahlekelwa kwentloko yenkqubo kunciphisa izinga lokuhamba kwaye nakwiimeko ezinzima kunokukhokelela ekuphazamiseni ngokupheleleyo ukuhanjiswa kwamanzi. Ukuqinisa umonakalo we-cavitation, ukukhawulezisa ukubola kweendawo zetsimbi, ukwandisa ukuguquguquka koxinzelelo kwinkqubo, ukwandisa iimpazamo zesixhobo semitha, kunye nokuqhuma kwegesi. Ukuphucula ukusebenza kakuhle konikezelo lwamanzi ekusebenzeni kwemibhobho.

Umgaqo wokusebenza:

Inkqubo yokusebenza yevalve yomoya edibeneyo xa umbhobho ongenanto uzaliswe ngamanzi:
1. Khupha umoya kumbhobho ukwenza ukuzaliswa kwamanzi kuqhubeke kakuhle.
2. Emva kokuba umoya okwipayipi ukhutshiwe, amanzi angena kwivalvu yokungenisa umoya kunye neyokukhupha umoya enexinzelelo eliphantsi, kwaye ifloat iphakanyiswa yi-buoyancy ukuze ivale izibuko zokungenisa umoya kunye nezokukhupha umoya.
3. Umoya okhutshwe emanzini ngexesha lenkqubo yokuhanjiswa kwamanzi uya kuqokelelwa kwindawo ephakamileyo yenkqubo, oko kukuthi, kwi-valve yomoya ukuze ithathe indawo yamanzi asekuqaleni kwi-valve body.
4. Ngokuqokelelwa komoya, inqanaba le-liquid kwi-high-pressure micro exhaust valve lihla, kunye nebhola le-float nalo lihla, ukutsala i-diaphragm ukutywina, ukuvula i-exhaust port, kunye nokukhupha umoya.
5. Emva kokuba umoya ukhutshiwe, amanzi angena kwakhona kwivalvu yokukhupha umoya enomxinzelelo ophezulu, ayidada ibhola edadayo, aze ayivale i-port yokukhupha umoya.
Xa inkqubo isebenza, la manyathelo angentla 3, 4, 5 aya kuqhubeka nokujikeleza
Inkqubo yokusebenza yevalve yomoya edibeneyo xa uxinzelelo kwinkqubo luphantsi koxinzelelo kunye noxinzelelo lwe-atmospheric (ukuvelisa uxinzelelo olubi):
1. Ibhola edadayo ye-low pressure intake kunye nevalve yokukhupha iya kulahla ngokukhawuleza ukuvula i-intake and exhaust port.
2. Umoya ungena kwinkqubo ukusuka kweli nqaku ukuphelisa uxinzelelo olubi kunye nokukhusela inkqubo.
