Hlola i-Valve vs Foot Valve: Umehluko Oyinhloko, Izicelo & Indlela Yokukhetha

Ivalve yokuhlola imisa ukubuyela emuva noma yikuphi epayipini, kuyilapho i-valve yonyawo iyivalvu yokuhlola ene-strainer eyakhelwe ngaphakathi, efakwe ngaphansi komugqa wokumunca iphampu ukuze kugcinwe iphampu iqala ukusebenza. Yonke i-valve yonyawo iyi-valve yokuhlola, kodwa akuwona wonke ama-valve okuhlola angasebenza njenge-valve yonyawo. Lo mhlahlandlela uchaza ukuthi lezi zinto zombili zihluke kanjani, ukuthi ngayinye ingeyakho, nokuthi ungakhetha kanjani phakathi kwakho kumasistimu amapayipi e-PVC-U/C (UPVC).

Bheka i-Valve vs i-Foot Valve ngokubuka nje

Iyini I-Check Valve?

I-valve yokuhlola, ebizwa nangokuthi i-valve engabuyi noma yendlela eyodwa, ivumela uketshezi ukuba ludlule ohlangothini olulodwa kuphela. Ayidingi isibambo noma injini: ukugeleza ngokwayo kuyayivula, futhi ingcindezi ehlehlayo, amandla adonsela phansi noma isiphethu ivala.

Indlela I-valve Yokuhlola Isebenza

Uma umfutho okhuphuka nomfula udlula umfutho ophansi komfula, ibhola langaphakathi, idiski noma i-poppet iphakamisa esihlalweni sayo. Lapho ukugeleza kuma noma kuhlehla, kuhlala futhi kuvale. Ingcindezi encane ekhuphuka nomfula edingekayo ukuze uyivule ibizwa ngokuthi ingcindezi yokuqhekeka, futhi iyahlukahluka ngokuklama.

Izinhlobo Ezivamile zama-Check Valves

• I-valve yokuhlola i-Swing

• Ivalvu yokuhlola inyunyana eyodwa

• I-valve yokuhlola inyunyana yeqiniso

Iyini I-Fit Valve?

I-valve yonyawo iyivalvu yokuhlola eyenzelwe ukuphela komugqa wokumunca iphampu. Umsebenzi wayo ukubamba amanzi epayipini lapho iphampu ima, ngakho-ke iphampu ihlala iqinile futhi ayipheli lapho iqala kabusha.

Izingxenye Ezibalulekile: Hlola Inqubo kanye Nesihlungi

I-valve yonyawo ihlanganisa isici sokuvala sendlela eyodwa nesikrini se-strainer endaweni yokungena. I-strainer igcina amaqabunga, isihlabathi namatshe amancane ngaphandle kwepompo. Ivula ngomfutho ophansi ngakho iphampu ayidingi ukusebenza kanzima ukuze iphakamise amanzi.

Izinhlobo Ezivamile Zamavalvu Ezinyawo

• I-valve yonyawo lwe-Swing

• I-valve yonyawo olulodwa

Hlola i-Valve vs i-Foot Valve: I-7 Umehluko Obalulekile

1. Umsebenzi

I-valve yokuhlola ivimbela kuphela ukubuyela emuva. I-valve yonyawo ivimbela ukugeleza emuva futhi, okubaluleke kakhulu, igcina iphampu isebenza kahle.

2. Indawo yokufaka

I-valve yokuhlola ingahlala noma yikuphi ukugeleza okubuyela emuva kufanele kumiswe, njengokukhishwa kwepompo noma umugqa wegatsha. I-valve yonyawo ihlale ihamba phansi komugqa wokumunca.

3. I-Strainer eyakhelwe ngaphakathi

I-valve yonyawo ihlanganisa i-strainer. Ivalve yokuhlola ejwayelekile ayinayo futhi ilindele uketshezi oluhlanzekile.

4. Ukuvula (Ukuqhekeka) Ingcindezi

I-valve yonyawo ivuleka ngokucindezela okuncane kakhulu ukuze iphampu ikwazi ukudonsa amanzi phezulu kalula. I-valve yokuhlola elayishwe entwasahlobo idinga ingcindezi eyanele ukuze inqobe intwasahlobo.

5. Flow Direction kanye Orientation

I-valve yonyawo igeleza iye phezulu isuka emthonjeni iye empompini. Ivalvu yokuhlola isebenza ngamapayipi avundlile noma aqondile, kuye ngomklamo wayo, inqobo nje uma umcibisholo ufana nokugeleza.

6. Indawo yokusebenza

I-valve yonyawo ihlala icwile. I-valve yokuhlola ingase yome noma ibe manzi.

7. Isondlo

Izihlungi ze-valve ezinyaweni ziyavaleka futhi kufanele zihlanzwe. Ama-valve okuhlola awadingi ukunakwa okuncane ngaphandle uma isigxivizo sigqoka noma imfucumfucu ibambe isihlalo sivuliwe.

Ingabe I-Check Valve Ingathatha Indawo Yevaluvu Yezinyawo?

Ngokuvamile akunjalo. I-valve yokuhlola engenalutho ngaphansi komugqa wokumunca ayinaso isihlungi, ngakho-ke udoti ungafinyelela iphampu, futhi ukucindezela kwayo kokuvula okuphezulu kungenza ukuqhuma kube nzima. Ingasebenza kuphela lapho uketshezi luhlanzekile futhi ivalvu ivuleka kalula ngaphansi kokumuncwa. Okuhlehlayo nakho kuyahluleka: i-valve yonyawo emugqeni wokukhipha iphampu yengeza isihlungi lapho kungadingeki khona.

Lapho Kufanele Kusetshenziswe Ivavu Ngayinye

Foot Valve Izicelo

Amavalvu ezinyawo angawanoma yikuphi lapho iphampu idonsa khona emthonjeni ophansi: imithombo, amachibi kanye nemifula yokunisela, amathange okugcina namathangi, imigodi ye-sump, kanye namanzi okuphuza amanzi. I-strainer ivikela iphampu emanzini anemfucumfucu-anzima.

Hlola Izicelo Valve

Amavalvu okuhlola avikela amaphampu namapayipi emigqeni yokukhipha amanzi, avimbele ukugeleza emuva kokwelashwa kwamanzi nemigqa yokudosa ngamakhemikhali, futhi agcine ukugeleza ngendlela eyodwa kumasekhethi egatsha nemigqa yamanzi angcolile.

Kungani Khetha Amavalvu Wokuhlola i-PVC-U/C namaVave Ezinyawo?

• Ukumelana nokugqwala: I-PVC-U/C ayigqwali, evumelana nokwelashwa kwamanzi, ukuchelela kanye nemigqa eminingi yamakhemikhali.

• Ilula futhi iyonga kakhulu kunethusi noma ama-valve ensimbi engagqwali anosayizi ofanayo.

• Yazi imikhawulo: I-PVC-U/C ayihloselwe isevisi yezinga lokushisa eliphezulu, ngakho hlola i-medium yakho kanye nezinga lokushisa ngokumelene nesilinganiso se-valve.

Indlela Yokukhetha I-Valve Elungile: Uhlu Lokuhlola Lokukhetha

Uhlobo Loketshezi kanye Nezinga Lemfucumfucu

Uma amanzi ethwala isihlabathi, amaqabunga noma inzika futhi ivalvu ihlala endaweni yokungena iphampu, khetha ivalvu yonyawo. Ukuze uthole uketshezi oluhlanzekile ngaphakathi kwepayipi, ivalvu yokuhlola yanele.

Uhlobo lwephampu kanye ne-Suction Lift

Amaphampu aphakamisa amanzi ngaphansi adinga i-valve yonyawo ukuze ahlale eqinile. Amaphampu anokumunca okugcwele amanzi noma adinga ukuvikelwa kokuphuma abiza ivalvu yokuhlola.

Usayizi Nokuxhumana

Qondanisa i-valve nosayizi wepayipi lakho kanye nohlobo oluhlangene: isokhethi (usimende oncibilikayo), ocushiwe noma owenziwe nge-flanged.

Amazinga

Qinisekisa izinga lobukhulu obusetshenziswa yiphrojekthi yakho, njenge-DIN, i-ASTM, i-JIS noma i-GB.

Isilinganiso Sokucindezela Nezinto Zokuvala

Qhathanisa ingcindezi yokusebenza nesistimu yakho, bese ukhetha ama-EPDM noma ama-FPM ama-seal ahambisana noketshezi.

Amathiphu okufaka

Ukufakwa kweValve Yezinyawo

• Gcina i-valve icwile ngokuphelele ukuze iphampu ingalokothi iwudonse umoya.

• Libambe lisuse phansi ethangini noma emthonjeni ukuze ugweme ukudonsa inzika.

• Yenza ukuxhumana kungangeni moya, njengoba ilunga elixegayo livumela umoya ungene bese iphampu ilahlekelwa umsebenzi.

Hlola Ukufakwa Kwevalvu

• Landela umcibisholo wokugeleza emzimbeni; i-valve ehlehlisiwe ivimba ukugeleza.

• Qinisekisa umumo ovunyelwe wohlobo, ngoba ama-valve okuhlola ama-swing adinga ihinge evundlile.

Ukuxazulula Izinkinga Ezivamile

• Iphampu iphelelwa amandla: hlola ukuvuza komoya okumuncayo, isisefo esivalekile, noma isihlalo esingavaleki.

• Ukugeleza okuphansi noma i-cavitation: hlanza i-strainer ye-valve yonyawo.

• I-Banging at shutdown (isando samanzi): ivalve yokuhlola i-swing ingase ivaleke kungazelelwe; cabangela uhlobo olugcwele intwasahlobo.

• Ukuvuza: hlola indandatho yophawu kanye nesihlalo ukuthi asikho yini imfucumfucu egugile noma evaleleke.
