Indlela yokukhipha umoyaivalvuimisebenzi

Umqondo ngemuva kwevalvu yokukhipha umoya ukuthi uketshezi oluku-float luhamba kancane kangakanani. I-float indiza ngokuzenzakalelayo ize ifike endaweni yokuvala yembobo yokukhipha umoya lapho izinga loketshezi lokukhipha umoya lifinyelela phezulu.ivalvuikhuphuka ngenxa yokuntanta koketshezi. Ingcindezi ethile izokwenza ibhola livale ngokuzenzakalelayo. Lapho ipayipi lisebenza, ibhola elintantayo liyama phansi kwesitsha sebhola bese likhipha umoya omningi. Lapho nje umoya osepayipini uphela, uketshezi luyangena ngaphakathiivalvu, igeleza esitsheni sebhola esintantayo, bese isunduza ibhola elintantayo emuva, okwenza lintante futhi livale.

Uma ipompo yehluleka, ingcindezi engemihle izoqala ukwakheka, ibhola elintantayo lizowa, futhi kuzosetshenziswa inani elikhulu lokumunca ukuze kulondolozwe ukuphepha kwephayiphi. Lapho i-buoy isiphelile, amandla adonsela phansi abangela ukuthi idonse uhlangothi olulodwa lwe-lever phansi. I-lever manje isesimweni esithambekile. Umoya ukhishwa emgodini womoya ngesikhala esikhona phakathi kwe-lever nengxenye yokuxhumana yembobo yomoya. Izinga loketshezi liyakhuphuka ngokukhululwa komoya, futhi i-float iyantanta phezulu ngenxa yokuntanta koketshezi. Indawo yokugcina yokuvala e-lever icindezelwa kancane kancane emgodini womoya kuze kube yilapho yonke imbobo yomoya ivaliwe ngokuphelele.

Ukubaluleka kwama-valve okukhipha umoya

Sekuyisikhathi eside kakhulu abantu bengakwazi ukuxazulula inkinga eyinhloko yokuvuza kwamanzi njalo kunethiwekhi yamapayipi ngoba abanalo ulwazi olwanele mayelana nokuthi amapayipi okusabalalisa amanzi asemadolobheni aqukethe igesi nokuthi angabangela ukuqhuma kwamapayipi yini. Ukuze siqonde kangcono i-water hammer yohlobo lwamanzi anqamukile aqukethe igesi, kubalulekile ukuthi sichaze izimbangela ezingaba khona zokugcinwa kwegesi ngesikhathi sokusebenza kwenethiwekhi yokuphakelwa kwamanzi evamile kanye nombono wokwanda kwengcindezi yepayipi kanye nokuqhuma kwamapayipi.

1. Ukukhiqizwa kwegesi kunethiwekhi yamapayipi okuhambisa amanzi kubangelwa kakhulu yizimo ezinhlanu ezilandelayo. Lona umthombo wegesi kunethiwekhi yamapayipi okusebenza evamile.

(1) Inethiwekhi yamapayipi inqanyuliwe kwezinye izindawo noma ngokuphelele ngesizathu esithile;

(2) ukulungisa nokuthulula izingxenye ezithile zamapayipi ngokushesha;

(3) I-valve yokukhipha umoya kanye nepayipi akuqinile ngokwanele ukuvumela ukujova kwegesi ngoba izinga lokugeleza komuntu oyedwa noma ngaphezulu abasebenzisi abakhulu lishintshwa ngokushesha kakhulu ukuze kudalwe ingcindezi engemihle epayipini;

(4) Ukuvuza kwegesi okungagelezi;

(5) Igesi ekhiqizwa yingcindezi engemihle yokusebenza ikhishwa epayipini lokumunca ipompo yamanzi kanye ne-impeller.

2. Izici zokunyakaza kanye nokuhlaziywa kwengozi yesikhwama somoya senethiwekhi yamapayipi okuhambisa amanzi:

Indlela eyinhloko yokugcina igesi epayipini ukugeleza kwe-slug, okubhekisela kugesi ekhona phezulu kwepayipi njengezindawo eziningi zomoya ezizimele ezingaqhubeki. Lokhu kungenxa yokuthi ububanzi bepayipi lenethiwekhi yamapayipi okuhambisa amanzi buyahlukahluka kusukela kokukhulu kuya kokuncane ngokuya kokugeleza kwamanzi okuyinhloko. Okuqukethwe kwegesi, ububanzi bepayipi, izici zesigaba sepayipi eside, nezinye izici zinquma ubude besikhwama somoya kanye nendawo enqamula amanzi esetshenziswayo. Izifundo zethiyori kanye nokusetshenziswa okusebenzayo kubonisa ukuthi ama-airbag ahamba ngokugeleza kwamanzi phezulu kwepayipi, avame ukuqongelela eduze kwama-pipe bends, ama-valve, nezinye izici ezinobubanzi obuhlukahlukene, futhi akhiqize ukunyakaza kwengcindezi.

Ubunzima bokushintsha kwejubane lokugeleza kwamanzi buzoba nomthelela omkhulu ekukhuphukeni kwengcindezi okubangelwa ukunyakaza kwegesi ngenxa yezinga eliphezulu lokungabikezeleki kwejubane lokugeleza kwamanzi kanye nesiqondiso kunethiwekhi yamapayipi. Ukuhlolwa okufanele kukhombisile ukuthi ingcindezi yayo ingakhuphuka ifike ku-2Mpa, okwanele ukuphula amapayipi ajwayelekile okuhambisa amanzi. Kubalulekile futhi ukukhumbula ukuthi ukushintshashintsha kwengcindezi kuyo yonke indawo kuthinta inani lama-airbag ahamba nganoma yisiphi isikhathi kunethiwekhi yamapayipi. Lokhu kwenza izinguquko zengcindezi zibe zimbi kakhulu ekugelezeni kwamanzi agcwele igesi, okwandisa amathuba okuqhuma kwamapayipi. Okuqukethwe kwegesi, isakhiwo samapayipi, kanye nokusebenza kwazo zonke izinto ezithinta izingozi zegesi kumapayipi. Izingozi zingahlukaniswa zibe izinhlobo ezimbili: ezicacile nezifihliwe, futhi izici zazo zimi kanje:

Izingozi ezisobala zifaka phakathi lezi zici ezilandelayo

(1) Ukukhishwa kwamanzi okunzima kwenza kube nzima ukudlulisa amanzi Uma amanzi negesi kusesigabeni, imbobo enkulu yokukhipha amanzi yevalvu yokukhipha yohlobo lwe-float ayenzi umsebenzi ophelele futhi ithembele kuphela ekukhishweni kwamanzi okuphumayo kwe-micropore, okubangela "ukuvinjelwa komoya" okukhulu, okuvimbela umoya ukuthi uphele, okubangela ukuthi amanzi ageleze ngokungalingani, kunciphisa noma kuqede indawo enqamulelayo yomsele wokugeleza kwamanzi, kuvimbela ukugeleza kwamanzi, kwehlisa amandla okujikeleza kohlelo, kuphakamisa izinga lokugeleza kwendawo, futhi kwandise ukulahlekelwa yikhanda lamanzi. Iphampu yamanzi idinga ukwandiswa, okuzobiza kakhulu ngamandla kanye nokuthuthwa, ukuze kugcinwe ivolumu yokujikeleza kokuqala noma ikhanda lamanzi.

(2) (2) Ngenxa yokugeleza kwamanzi nokuqhuma kwamapayipi okubangelwa ukukhishwa komoya okungalingani, uhlelo lokuhlinzeka ngamanzi alukwazi ukusebenza kahle. Ukuqhuma kwamapayipi amaningi kulethwa ama-valve okukhipha umoya, angakhipha umoya omncane. Ipayipi lokuhlinzeka ngamanzi lingabhujiswa ukuqhuma kwegesi okubangelwa ukukhishwa komoya okubi, okungafinyelela ingcindezi efinyelela kuma-atmospheres angu-20 kuya kwangu-40 futhi linamandla okubhubhisa alinganayo ama-atmospheres angu-40 kuya kwangu-80 okucindezela okungaguquki. Ngisho nensimbi eqinile ethambile esetshenziswa kwezobunjiniyela ingalimala. Onjiniyela baseKolishi Lobunjiniyela banquma ngemuva kokuhlaziya ukuthi kwakuwukuqhuma kwegesi. Ingxenye yepayipi lamanzi edolobheni eliseningizimu yayingama-860m ubude kuphela, inobubanzi bepayipi obuyi-DN1200mm, futhi ipayipi laqhuma izikhathi ezi-6 ngonyaka owodwa wokusebenza.

Umonakalo ovela ekuqhumeni kwegesi obangelwa ukukhishwa kwepayipi lamanzi okunganele okubangelwa yivalvu yokukhipha kungaba inani elincane kakhulu lokukhishwa kwepayipi, ngokusho kwesiphetho. Inkinga eyinhloko yokuqhuma kwepayipi ekugcineni ixazululwa ngokufaka ivalvu yokukhipha enamandla enamandla eshesha kakhulu engaqinisekisa inani elikhulu lokukhishwa kwepayipi.

(3) Ijubane lokugeleza kwamanzi kanye nokucindezela okuguquguqukayo epayipini kuyashintsha njalo, amapharamitha esistimu awazinzile, futhi ukudlidliza okukhulu nomsindo kungavela ngenxa yokukhululwa okuqhubekayo komoya oncibilikisiwe emanzini kanye nokwakheka okuqhubekayo nokwanda kwamapokhethi omoya.

(4) Ukugqwala kobuso bensimbi kuzosheshiswa ngokuchayeka emoyeni nasemanzini okunye.

(5) Ipayipi lidala imisindo engathandeki.

Izingozi ezifihliwe ezibangelwa ukugoba okungekuhle

1. Ukukhishwa komoya okungalingani kungabangela ukuthi ingcindezi yepayipi ishintshe, ukulungiswa kokugeleza kungabi nembile, ukulawulwa okuzenzakalelayo kwepayipi kungabi nembile, kanye nezinyathelo zokuvikela ukuphepha kungabi yimpumelelo;

2. Ukuvuza kwamanzi epayipini kukhuphukile;

3. Kunokwehluleka okwengeziwe kwamapayipi, futhi ukushaqeka okuqhubekayo kwesikhathi eside kwenza buthaka izindonga namajoyinti amapayipi, okuholela ezinkingeni ezifaka phakathi isikhathi esifushane sokuphila kanye nezindleko zokulungisa eziphakeme;

Izifundo eziningi zethiyori kanye nokusetshenziswa okusebenzayo kuye kwabonisa ukuthi kulula kangakanani ukukhiqiza isando samanzi esilimaza kakhulu, esiyingozi kakhulu epayipini, lapho ipayipi lamanzi elinomfutho liqukethe igesi eningi. Ukusetshenziswa kwesikhathi eside kuzonciphisa isikhathi sokuphila kodonga, kulwenze luqhekeke kakhulu, kwandise ukulahleka kwamanzi, futhi kungabangela ukuthi ipayipi liqhume.

Inkinga yokukhishwa komoya emapayipini iyimbangela eyinhloko yokuvuza kompompi wamanzi emadolobheni. Iphansi lompompi lidinga ukuhlanzwa, futhi ivalvu yokukhipha umoya engakhululwa iyisisombululo esingcono kakhulu. Ivalvu yokukhipha umoya enamandla enesivinini esikhulu manje iyahlangabezana nezidingo.

Ama-boiler, ama-air conditioner, amapayipi kawoyela negesi, amapayipi okuhambisa amanzi kanye nawokukhipha amanzi, kanye nokuthuthwa kwe-slurry okude konke kudinga i-valve yokukhipha umoya, eyingxenye ebalulekile yohlelo lwepayipi. Ivame ukufakwa ezindaweni eziphakeme noma ezindololwaneni ukuze kusulwe igesi eyengeziwe epayipini, kwandiswe ukusebenza kahle kwepayipi, kanye nokusetshenziswa kwamandla okuphansi.

Izinhlobo ezahlukene zama-valve okukhipha umoya

Inani lomoya oncibilikisiwe emanzini ngokuvamile licishe libe ngu-2VOL%. Umoya ukhishwa njalo emanzini ngesikhathi senqubo yokulethwa futhi uqoqana endaweni ephezulu yepayipi ukuze ukhiqize amaphakethe omoya (i-AIR POCKET), okwenza ukulethwa kwamanzi kube nzima futhi ngaleyo ndlela kungabangela ukwehla okungu-5-15% kumthamo wokulethwa kwamanzi ohlelweni. Inhloso eyinhloko yale valve encane yokukhipha umoya ukususa umoya oncibilikisiwe ongu-2VOL%, futhi ungafakwa ezakhiweni eziphakeme, emapayipini okukhiqiza, nasezikhungweni ezincane zokupompa ukuze kuvikelwe noma kuthuthukiswe ukusebenza kahle kokulethwa kwamanzi ohlelweni futhi kulondolozwe amandla.

Umzimba wevalvu wevalvu encane yokukhipha umoya ene-single-lever (SIMPLE LEVER TYPE) unesimo esifana neseqanda. Insimbi engagqwali engu-304S.S isetshenziselwa zonke izingxenye zangaphakathi, okuhlanganisa ama-floats, ama-lever, ozimele be-lever, kanye nezihlalo zevalvu. Ngaphakathi, kusetshenziswa amazinga embobo yokukhipha umoya engu-1/16″. Kufika kuzilungiselelo zokucindezela zokusebenza ze-PN25 ezifanele yona.
