Hlola isakhiwo se-valve isingeniso

Isakhiwo sevalvu yokuhlola sakhiwe kakhulu umzimba wevalvu, idiski yevalvu, intwasahlobo (ezinye izivalo zokuhlola zinayo) kanye nezingxenye ezingaba usizo njengesihlalo, isembozo sevalvu, isiqu sevalvu, iphini lehinji, njll. Okulandelayo incazelo eningiliziwe yesakhiwo sevalvu yokuhlola:

Okokuqala, umzimba we-valve

Umsebenzi: Umzimba wevalvu uyingxenye eyinhloko yevalvu yokuhlola, kanti isiteshi sangaphakathi sifana nobubanzi bangaphakathi bepayipi, okungaphazamisi ukugeleza kwepayipi uma lisetshenziswa.

Izinto: Umzimba we-valve uvame ukwenziwa ngensimbi (njengensimbi ephothiwe, ithusi, insimbi engagqwali, insimbi yekhabhoni, insimbi eyakhiwe, njll.) noma izinto ezingezona ezensimbi (njengepulasitiki, i-FRP, njll.), ukukhethwa kwezinto ezithile kuncike ezicini ze-medium kanye nengcindezi yokusebenza.

Indlela yokuxhuma: Umzimba we-valve uvame ukuxhunywa ohlelweni lwamapayipi ngokuxhumeka kwe-flange, uxhumano olunezintambo, uxhumano oluhlanganisiwe noma uxhumano lwe-clamp.

Okwesibili, idiski yevalvu

Umsebenzi: Idiski iyisici esibalulekile sevalvu yokuhlola, esetshenziselwa ukuvimba ukugeleza emuva kwe-medium. Ithembele emandleni e-medium esebenzayo ukuvula, futhi lapho i-medium izama ukubuyisela emuva ukugeleza, idiski yevalvu izovala ngaphansi kwesenzo sezici ezifana nomehluko wokucindezela kwe-medium kanye nobukhulu bayo.

Ukuma kanye nezinto: Idiski ivame ukuba yindilinga noma ibe yidiski, futhi ukukhethwa kwezinto kufana nokomzimba, futhi kungafakwa nesikhumba, irabha, noma izembozo zokwenziwa ensimbini ukuze kuthuthukiswe ukusebenza kokuvala.

Imodi Yokunyakaza: Imodi yokunyakaza yediski yevalvu ihlukaniswe ngohlobo lokuphakamisa kanye nohlobo lokujika. Idiski yevalvu yokuhlola ukuphakama ihamba phezulu naphansi ku-axis, kuyilapho idiski yevalvu yokuhlola ukujika ijikeleza umgodi ojikelezayo wendlela yesihlalo.

Okwesithathu, intwasahlobo (amanye ama-valve okuhlola anayo)

Umsebenzi: Kwezinye izinhlobo zama-check valve, njenge-piston noma ama-cone check valve, iziphethu zisetshenziselwa ukusiza ukuvala i-disc ukuvimbela i-water hammer kanye nokugeleza kwamanzi okuphambene. Lapho ijubane lokuya phambili lehla, i-spring iqala ukusiza ekuvaleni i-disc; Uma ijubane lokungena phambili liyi-zero, i-disc ivala isihlalo ngaphambi kokuba kubuye.

Okwesine, izingxenye ezisizayo

Isihlalo: nediski yevalvu ukwakha indawo yokuvala ukuqinisekisa ukusebenza kokuvala kwevalvu yokuhlola.

I-Bonnet: Imboza umzimba ukuze ivikele izingxenye zangaphakathi njengediski kanye nesipilingi (uma zikhona).

Isiqu: Kwezinye izinhlobo zama-check valve (njengezinye izinhlobo zama-lift check valve), isiqu sisetshenziselwa ukuxhuma i-disc ku-actuator (njenge-lever esetshenziswa ngesandla noma i-electric actuator) ukuze kulawulwe ngesandla noma ngokuzenzakalelayo ukuvulwa nokuvalwa kwe-disc. Nokho, qaphela ukuthi akuwona wonke ama-check valve aneziqu.

Iphinikhodi yehinge: Kuma-valve okuhlola i-swing, iphinikhodi yehinge isetshenziselwa ukuxhuma idiski nomzimba, okuvumela idiski ukuthi ijikeleze kuyo.

Okwesihlanu, ukuhlukaniswa kwesakhiwo

I-valve yokuhlola ukuphakama: Idiski iya phezulu naphansi ku-axis futhi ngokuvamile ingafakwa kuphela kumapayipi avundlile.

I-valve yokuhlola ukujika: Idiski ijikeleza umgodi wesiteshi sesihlalo futhi ingafakwa ngepayipi elivundlile noma eliqondile (kuye ngokuthi idizayini).

I-valve yokuhlola ubhathane: Idiski ijikeleza iphini esihlalweni, isakhiwo silula kodwa ukuvala akukuhle.

Ezinye izinhlobo: Zihlanganisa nama-valve okuhlola isisindo esindayo, ama-valve angaphansi, ama-valve okuhlola intwasahlobo, njll., uhlobo ngalunye lunesakhiwo salo esithile kanye nezimo zokusetshenziswa.

Okwesithupha, ukufakwa nokugcinwa

Ukufakwa: Uma ufaka i-check valve, qiniseka ukuthi isiqondiso sokugeleza okuphakathi sihambisana nesiqondiso somcibisholo ophawulwe emzimbeni we-valve. Ngesikhathi esifanayo, kuma-check valve amakhulu noma izinhlobo ezikhethekile zama-check valve (njenge-swing check valve), indawo yokufaka kanye nemodi yokusekela kufanele futhi kucatshangelwe ukuze kugwenywe isisindo noma ingcindezi engadingekile.

Ukugcinwa: Ukugcinwa kwevalvu yokuhlola kulula kakhulu, okuhlanganisa nokuhlolwa njalo kokusebenza kokuvala kwediski nesihlalo sevalvu, ukuhlanza ukungcola okuqongelelekile nokushintsha izingxenye ezigugile kakhulu. Kumavalvu okuhlola anezipilingi, ukuqina kanye nesimo sokusebenza kwezipilingi kufanele kuhlolwe njalo.

Ngamafuphi, isakhiwo sevalvu yokuhlola senzelwe ukuqinisekisa ukuthi i-medium ingageleza ohlangothini olulodwa kuphela futhi ivimbele ukugeleza emuva. Ngokukhetha umzimba ngokufanele, idiski nezinye izingxenye zezinto zokwakha kanye nesakhiwo, kanye nokufakwa nokugcinwa okufanele kwevalvu yokuhlola, ingaqinisekisa ukusebenza kwayo okuzinzile isikhathi eside futhi idlale umsebenzi olindelekile.
