Impela uzwile izikhathi ezingaphezu kwesisodwa "I-valve ye-solenoid" kwamanye amawebhusayithi, izincwadi, ngisho nakumabonakude. Abaningi bayasikhumbula leso sigameko senganekwane sikaTom Cruise ku War of the Worlds lapho ephimisa khona leli gama, noma enguqulweni ebhuqayo Scary Movie 4. Awu lokhu ingxenye kagesi Ingasetshenziselwa inqwaba yezinhlelo zokusebenza, futhi isebenza ngokuthakazelisa kakhulu. Lapha uzofunda okwengeziwe ngaye. Mhlawumbe ngandlela thize ikukhumbuza a edluliselwe, noma ezinye izingxenye esezibonile.
Iyini i-valve ye-solenoid?
Umdwebo wevalvu wenjini evuthayo yangaphakathi kanye nophawu lwayo
La i-valve ye-solenoid Ikhona ngobuningi bezinhlelo zamanje, kusukela kumasekhethi asefrijini kuya ezimotweni, ngokufaka igesi, njll. Kuyidivayisi ekwazi ukusetshenziswa ngokushintsha kwe-thermostatic, ama-relay, njll., okungukuthi, isetshenziswa ngogesi. Umsebenzi wayo ukulawula ukugeleza koketshezi noma amagesi ngokuvula noma ukuvala i-valve ukuvumela indlela noma ukumpintsha uketshezi olushiwo. Ngamanye amazwi, iwuhlobo lwesimpompi esisebenza ngogesi.
Lolu hlobo lwe-valve luqukethe Izingxenye ezimbili idrayivu eyisisekelo:
- I-Solenoid: Kuyidivayisi esesimweni sekhoyili kagesi (inxeba kanye nentambo yethusi evalekile) ekwazi ukudala insimu kazibuthe ngaphakathi kwayo. Le nkambu iqine kakhulu ngaphakathi futhi ibuthakathaka ngaphandle, iba nguzibuthe kagesi okwazi ukwenza kusebenze noma ukulawula okuthile (iheha izinsimbi ezisansimbi), kulokhu ukuvulwa noma ukuvala kwevalvu. Eqinisweni, le solenoid ngokuvamile ibizwa ngokuthi opharetha.
- Umzimba we-valve: Umsebenzisi uzofakwa kuwo, futhi ngaphakathi kwalo mzimba kuzoba nepiston yokuvula noma yokuvala lapho u-opharetha azosebenza khona. Futhi yakhiwe:
- I-Plunger (ebizwa nangokuthi inaliti noma isiqu): lapho inkambu kazibuthe ikhiqizwa, i-plunger izokhangwa phakathi nendawo ye-solenoid futhi i-valve ivule futhi ivumele uketshezi ukuthi ludlule. Uma ingekho indawo kazibuthe esetshenziswayo, i-plunger izohlala ivaliwe futhi ngeke ivumele uketshezi ukuba ludlule.
- Isikhumulo: i-orifice okugeleza kuyo uketshezi noma igesi uma ivuliwe.
I-valve ye-solenoid isebenza kanjani?
I-valve ye-solenoid ine-a Isimiso sokusebenza esilula. Sengike ngaphawula ngalokhu esigabeni esandulele, kodwa manje ake sibone inqubo yesinyathelo ngesinyathelo:
- I-valve ye-solenoid ihlala ivaliwe lapho i-solenoid inganikezwa amandla. Ngale ndlela, awekho insimu kazibuthe noma amandla akhangayo akhiqizwa kuwo. Isisindo se-plunger sibangela ukuthi iwe ngamandla adonsela phansi futhi ivale umgodi, okungukuthi, i-plunger iphumule futhi akukho ukugeleza okuvunyelwe.
- Uma i-solenoid inikwa amandla, inaliti exhunywe ngokuzenzakalelayo phansi kwe-plunger izokhuphuka njengoba indawo kazibuthe iphakamisa i-plunger futhi i-plunger iphinde idonse inaliti, iveze imbobo futhi ivumele ukugeleza.
Kodwa-ke, ezinye izinhlobo zama-valve zisebenza ngokuhlukile, njengalezo ezisebenzayo iziphethu noma iziphethu ukusunduza i-plunger ukuvala i-valve. Lokhu kuzovumela ukuthi ama-valve afakwe kwezinye izindawo ngaphandle kokuma mpo (esebenza ngamandla adonsela phansi).
Uma uzibuza i-solenoid ingasebenza kanjani, Kulula kakhulu. Iphakelwa ngamandla kagesi futhi ezokhiqiza insimu kazibuthe. Yebo, ukunikezwa kwamandla kungalawulwa ukuze kuvuleke noma kucishwe kuphela lapho kudingeka. Ukwenza lokhu, kungenziwa ngokushintsha okulula kokuvula/ukuvala imanuwali, noma kungaba isistimu yempendulo eyinkimbinkimbi kakhulu ethola izimo ezithile ngezinzwa futhi ihlelelwe ukuvula noma ukuvala i-valve ngokusekelwe kulokho.
Izinzuzo
I-valve ye-solenoid ine izinzuzo ezithile Okufanele kuqashelwe:
- Aphephile: Amanye ama-valve angadala ukuvuza ngenxa yokucindezela okukhulu, ukuguga, amaphutha okufakwa, njll. Futhi uma usebenza ngoketshezi oluvutha umlilo, olunobuthi, olubolayo, njll., kungaba yingozi enkulu. Ku-valve ye-solenoid, izimbobo zokungena nezokuphuma zingavinjelwa kalula esimeni esiphuthumayo.
- Isenzo esisheshayo: Ngenxa yalawa ma-valve, ukugeleza kungadedelwa noma kunqanyulwe endabeni yama-millisecond. Lokho kuvumela ukulawula ukugeleza okungcono.
- Okuthembekile: Njengoba ziwuhlelo olulula kangako, ngokuvamile zihlala isikhathi eside futhi azidingi ukunakekelwa. Ngaphezu kwalokho, ashibhile futhi ungawathola ngamasayizi ahlukene ukuze avumelane namapayipi noma amashubhu wezinhlelo ze-hydraulic, pneumatic, njll.
- Okuzenzakalelayo: Aqeda isidingo sedrayivu yesandla ukuze ulawule ukugeleza, futhi lokho kuwenza anembe kakhudlwana.
- Kulula: ukufaka nohlelo.
Aplicaciones
Uma uzibuza iyini i-valve ye-solenoid, Nazi ezinye izinhlelo zokusebenza ezijwayelekile zalawa madivaysi kumasekhethi we-hydraulic (uketshezi oluwuketshezi) kanye ne-pneumatic (ama-gaseous fluids):
- Ukulawula ukucindezela kwamanzi
- Ukulawulwa kwamazinga okushisa ahilelekile
- I-Fluid Viscosity Control
Izinhlobo zama-valve e-Solenoid
Omunye umbuzo ovame ukubuzwa ukuthi yiziphi izinhlobo ezahlukene ama-valve solenoid? Ukuyiphendula, ake sibone izinhlobo ze-valve ye-solenoid:
- shayela ngqo: Lolu hlobo lwama-valve e-solenoid lungasebenza ngisho nangaphansi kwezimo ze-vacuum. Akusetshenziswa okulinganiselwe, angama-10% kuphela wabasebenzi. Futhi-ke, zingaba:
- N/C: Ivamise Ukuvalwa, lapho ukunika amandla i-solenoid kuyibangela ukuthi ivuleke futhi ingawasebenzisi amandla okwenza ukuthi ihlale ivaliwe.
- N/O: Ngokujwayelekile Vula, okungukuthi okuphambene kwalokhu okungenhla, lapho isiphethu sibamba ivalvu ivuliwe lapho i-solenoid inganikiwe amandla futhi iphushe ivaliwe lapho inikwe amandla.
- Umshayeli wangaphakathi: kulezi zimo, i-solenoid izosebenzisa ukucindezela kwangaphakathi ukulawula i-valve, ngakho-ke kuzodingeka isebenzise amandla kagesi amancane kunangaphambili.
- umshayeli wangaphandle: efana neyangaphambili, kodwa sebenzisa ingcindezi yangaphandle ukuze ukhuthaze ukunyakaza kwe-valve. Lokhu kusiza i-solenoid ukuze kungadingeki amandla amaningi.
Indlela yokukhetha i-valve ye-solenoid efanele
Ngesikhathi sika khetha i-valve ye-solenoid ezifanele kakhulu izidingo zakho, kufanele ucabangele izici eziningana:
- Umfutho wesifunda: kubalulekile ukwazi ukuthi yini ingcindezi yesifunda lapho i-valve izofakwa khona, ngoba lokhu kunganquma uhlobo lwe-valve esetshenziselwa ukulondoloza amandla.
- Isivinini esidingekayo: isivinini i-valve evula noma evala ngaso nayo ingesinye isici esibalulekile, ikakhulukazi uma sidingeka ohlelweni lapho ukunemba ekulawuleni ukugeleza kubalulekile. Isibonelo, ukulinga kuhamba kancane kunesenzo esiqondile.
- I-N/C vs. N/O: Lokhu kungase futhi kuphazamise ukusetshenziswa. Ngokuvamile, uma umugqa wokugeleza uvaliwe isikhathi esiningi futhi udinga kuphela ukuvulwa ngezikhathi ezithile, i-N/C iyisinqumo esifanele, njengoba amandla ku-solenoid azodinga ukusetshenziswa ngezikhathi ezithile kuphela. Esimeni lapho ukugeleza kuvame ukuvuleka futhi kudinga ukuvalwa kuphela kwezinye izimo, khona-ke i-N/O iba ngcono.
- izinga lokugeleza: Kubalulekile ukunquma ukugeleza okufanele kuphathwe ukuze kunqunywe usayizi wembobo noma inombolo yezimbobo (izimbobo).
- Usayizi: kufanele futhi ifanele ukufakwa ohlelweni futhi ihambisane nobukhulu bepayipi.
- Voltage: Uzothola namavalvu anezici ezihlukile zikagesi, njenge-voltage. Lokhu kufanele kuhambisane nalokho okudingayo.
Yebo, khumbula ukuthi uzodinga ezinye izesekeli ezengeziwe zokufaka kwakho, njengokuxhunywa kanye nesekhethi yokulawula kagesi edingekayo, amashubhu noma amapayipi, njll.
Ungathenga kuphi i-valve ye-solenoid eshibhile
Okokugcina, uma ucabanga nge- thenga i-valve ye-solenoid eshibhile, ungazithola kwezinye izitolo ezikhethekile, noma ezinkundleni zokuxhumana ezifana ne-Amazon:
