I-valve encane yokugeleza, eyaziwa nangokuthi i-automatic recirculation valve, iyi-valve yokuvikela iphampu efakwe endaweni yokuphuma iphampu ye-turbine enezigaba eziningi ukuvimbela umonakalo obangelwa ukushisa ngokweqile, umsindo omkhulu, ukungazinzi kanye ne-cavitation lapho ipompo isebenza ngaphansi komthwalo. . Uma nje izinga lokugeleza kwepompo liphansi kunevelu ethile, imbobo yokubuya ye-bypass yevalvu izovuleka ngokuzenzakalelayo ukuze kuqinisekiswe izinga lokugeleza elincane elidingekayo oketshezini .

1. Ukusebenza ngesimiso

I-valve encane yokugeleza ixhunywe ku-outlet ye- iphampu ye-turbine enezigaba eziningi . Njenge-valve yokuhlola, incike ekugxilweni kwe-medium ukuze uvule i-disc valve. Lapho ukucindezela kwesiteshi esiyinhloko kuhlala kungashintshiwe, izinga lokugeleza kwesiteshi esikhulu lihlukile, futhi ukuvulwa kwediski ye-valve kuhlukile. I-valve eyinhloko I-flap izonqunywa endaweni ethile, futhi i-valve flap yesiyingi esikhulu izodlulisela isenzo se-valve eyinhloko ku-bypass ngokusebenzisa i-lever ukuze kubonakale isimo sokushintsha se-bypass.

2. Inqubo Yokusebenza

Lapho i-disc ye-valve eyinhloko ivula, i-disc ye-valve ishayela isenzo se-lever, futhi i-lever force ivala i-bypass. Lapho izinga lokugeleza esiteshini esikhulu liyancipha futhi i-disc ye-valve enkulu ayikwazi ukuvulwa, i-disc ye-valve eyinhloko izobuyela endaweni yokuvala ukuze ivale isiteshi esikhulu. I-valve disc iphinda iqhube isenzo se-lever, i-bypass iyavuleka, futhi amanzi ageleze esuka ku-bypass ukuya ku-deaerator. Ngaphansi kwesenzo sokucindezela, amanzi agelezela ekungeneni kwepompo futhi aphinde ajikeleze, ngaleyo ndlela avikele iphampu.

I-3. Izinzuzo

I-valve encane yokugeleza (ebuye ibizwe ngokuthi i-automatic control valve, i-automatic recirculation valve, i-automatic return valve) iyivalvu enemisebenzi eminingi ehlanganiswe kweyodwa.

Izinzuzo:

1. I-valve encane yokugeleza iyi-valve ezilawulayo ezisebenza yona. Umsebenzi we-lever uzolungisa ngokuzenzakalelayo ukuvulwa kwe-bypass ngokwezinga lokugeleza (ukulungiswa kokugeleza kwesistimu). Inesakhiwo somshini ngokuphelele futhi incike ku-valve yokulawula ukugeleza futhi ayidingi amandla engeziwe.

2. Ukugeleza kwe-bypass kungalungiswa futhi kulawulwe, futhi ukusebenza jikelele kwe-valve kunonga kakhulu.

3. Kokubili umzila oyinhloko kanye ne-bypass isebenza njengama-valve okuhlola.

4. Isakhiwo esinezinhlangothi ezintathu esimise okwe-T, esilungele amapayipi okujikeleza kabusha.

5. I-Bypass ayidingi ukugeleza okuqhubekayo futhi inciphisa ukusetshenziswa kwamandla.

6. Multi-function ehlanganiswe kokukodwa, ukunciphisa umsebenzi wokuklama.

7. Inezinzuzo ezibalulekile zezindleko mayelana nokuthengwa komkhiqizo kusenesikhathi, ukufakwa nokulungiswa, kanye nokugcinwa kwakamuva, ukunciphisa izindleko zokuwufaka nokuwulungisa, futhi izindleko zizonke ziphansi kunezinhlelo zamavalvu zokulawula ezivamile.

8. Nciphisa ukuthi kungenzeka yini ukwehluleka, unciphise amathuba okuhluleka okubangelwa uketshezi olunesivinini esikhulu, futhi uqede izinkinga ze-cavitation nezindleko zezintambo zikagesi.

9. Ukusebenza okuzinzile kwe-multistage iphampu ye-turbine eqondile isengaqinisekiswa ngaphansi kwezimo zokugeleza okuphansi.

10. Ukuvikelwa kwepompo kudinga i-valve eyodwa kuphela futhi azikho ezinye izingxenye ezengeziwe. Njengoba ingathinteki ngamaphutha, isiteshi esiyinhloko kanye ne-bypass iba iyonke, okwenza kucishe kungabi nasondlo.

4. ukufakwa

I-valve encane yokugeleza ifakwa lapho kuphuma khona iphampu futhi kufanele ifakwe eduze ngangokunokwenzeka nepompo ye-centrifugal evikelekile. Ibanga phakathi kokuphuma kwepompo kanye ne-inlet ye-valve akufanele lidlule amamitha angu-1.5 ukuvimbela umsindo we-low-frequency obangelwa ukushaywa koketshezi. Isando samanzi. Isiqondiso sokujikeleza sisuka phansi siye phezulu. Ukufakwa okuqondile kuyakhethwa, kodwa ukufakwa okuvundlile nakho kungenzeka.

Izinyathelo Zokuqaphela Ukunakekela, Ukunakekela Nokusetshenziswa

1. I-valve kufanele igcinwe ekamelweni elomile, elingena umoya, futhi zombili iziphetho zesiteshi se-valve kufanele zivalwe.

2. Ama-valve agcinwe isikhathi eside kufanele ahlolwe njalo ukuze kukhishwe ukungcola. Ukunakwa okukhethekile kufanele kukhokhwe ekuhlanzweni kwendawo yokuvala ukuvimbela ukulimala endaweni yokuvala.

3. Ngaphambi kokufaka, kufanele uhlole ngokucophelela ukuthi umaki we-valve uyahambisana yini nezidingo zokusetshenziswa.

4. Ngaphambi kokufaka, hlola i-valve yangaphakathi nendawo yokuvala. Uma kukhona ukungcola, kusule kuhlanzeke ngendwangu ehlanzekile.

5. I-valve kufanele ihlolwe njalo ngemva kokusetshenziswa ukuhlola indawo yokuvala kanye ne-O-ring. Uma ilimele futhi yehluleka, kufanele ilungiswe noma ishintshwe ngesikhathi.
