Uma uke wabhekana nokugeleza kwamanzi ohlelweni lokupompa, usuvele uyazi ukuthi kungacasula kangakanani - futhi kubize kangakanani -. Esinye sezixazululo ezilula nezithembekile kakhulu yi-I-Ball Check ValveAkuyona ingxenye ekhazimulayo kakhulu ekwakhiweni kwepayipi lakho, kodwa uma isebenza, awuyiboni kahle. Yilokho okushiwoyo.
Kulesi sihloko, ngizokukhombisa ukuthi i-valve yokuhlola ibhola yenzani ngempela, ukuthi iqhathaniswa kanjani namanye ama-valve ongase ucabange ngawo, nokuthi kungani ngezinye izikhathi ibhola eligingqikayo elidala liseyisinqumo esingcono kakhulu.
Iyini i-BallCheck Valve? (Isingeniso)
I-Ball Check Valvi-e uhlobo lwe-I-Valve Engabuyisi. Ivumela uketshezi lugeleze ohlangothini olulodwa futhi ivimbele ngokuzenzakalelayo ukugeleza okuphambene. Into yokuvala – uqagele – ibhola. Ngokuvamile yenziwe ngensimbi engagqwali, irabha, noma ngezinye izikhathi ipulasitiki efana ne-PTFE.
Ngokungafani ne-valve yesango noma i-valve yebhola (uhlobo olune-lever), i-valve yokuhlola ibhola ayidingi isibambo, i-actuator, futhi ayidingi ukungenelela ngesandla. Isebenza ngokuphelele ekuhlukeni kwengcindezi.
Indlela ivalvu yokuhlola ibhola esebenza ngayo (indlela eyisisekelo)
Ngaphakathi komzimba wevalvu, kukhona umgodi lapho ibhola lihlala khona ngokukhululeka. Uma uketshezi lungena luvela ohlangothini lokungena, lusunduza ibhola esihlalweni salo. Uketshezi lugeleza luzungeze ibhola luphume ngombhobho. Lapho ingcindezi yokungena yehla noma ukugeleza okuphambeneyo kuzama ukwenzeka, ibhola lisunduzelwa emuva esihlalweni. Lokho kuvala umgodi. Akukho ukugeleza okungemuva.
Kuzwakala kulula ngoba kunjalo. Futhi lokho kulula yingakho kunzima kangaka ukubulala la ma-valve.
Indima yebhola njengento yokuvala
Ibhola lenza umsebenzi ophindwe kabili. Liyingxenye ehambayo kanye nesivalo. Uma isihlalo sifakwe kahle futhi ibhola liyindilinga (okuzwakala kusobala, kodwa ama-valve ashibhile ngezinye izikhathi ayahluleka lapha), indawo yokuxhumana idala ukuvala okuqinile. Kuketshezi olungcolile noma uketshezi olunezinhlayiya ezincane, ibhola elimbozwe ngerabha lingavala kangcono kunelensimbi ngoba licindezela kancane esihlalweni.
Isebenza Kanjani I-Ball Check Valve?
Ake sithole imininingwane eyengeziwe mayelana nendlela esebenza ngayo. Ngoba uma ulinganisa ivalvu yesistimu yangempela, udinga ukwazi ukuthi kwenzekani ngaphakathi.
Izindlela Zokusebenza Zevalvu Yokuhlola Ibhola
Uma ipompo iqala, ijubane loketshezi lidala umehluko wokucindezela. Umfutho wokungena uyanda, umfutho wokuphuma usephansi. Lowo mehluko uphakamisa ibhola. Ibhola akudingeki likhuphuke kakhulu - ngokuvamile amamilimitha ambalwa nje. Yingakho ama-valve okuhlola ibhola enengcindezi ephansi yokuqhekeka. Uma ukugeleza kuma noma kubuyela emuva, amandla adonsela phansi kanye nomfutho wangemuva kubuyisela ibhola esihlalweni.
Ekufakweni okuvundlile, amandla adonsela phansi asiza ibhola ukuthi liwe phansi. Emigqeni eqondile (egeleza phezulu), ibhola liyawa phansi lapho ipompo ima. Eminye imiklamo yengeza isiphethu sokukhanya ukusiza ukuhlala ezinhlelweni ezinomfutho ophansi.
Izingxenye Eziyinhloko
Ivalvu yokuhlola ibhola eyisisekelo inezingxenye ezintathu ezibalulekile kuphela: umzimba, ibhola, kanye nesihlalo. Yilokho kuphela. Azikho izipilingi, azikho izihibe, azikho i-diaphragm. Ezinye izinhlobo zengeza isipilingi (ukuhlolwa kwebhola okugcwele intwasahlobo) ukuze kuphendulwe ngokushesha, kodwa ukwakheka kwe-"free-ball" yakudala kulula njengevalvu.
Umzimba ungaba yipulasitiki (i-PVC, i-CPVC), ithusi, insimbi engagqwali, noma insimbi ephonswe ngensimbi. Isihlalo sivame ukufakwa emzimbeni ngomshini noma senziwe ngezinto ezithambile ezifana ne-NBR noma i-EPDM.
Umdwebo Wevalvu Yokuhlola Ibhola
(Uma ubheka umdwebo wangempela njengamanje - cabanga ngakho.)
Cabanga ngepayipi elivundlile. Ngakwesobunxele kukhona indawo yokungena. Umzimba wevalvu uvuvukala kancane phakathi nendawo ukuze kwakheke igumbi. Ngaphakathi kwalelo gumbi, ibhola lihlala esihlalweni sohlangothi lwesobunxele uma livaliwe. Lapho ukugeleza kungena kusuka kwesobunxele, ibhola liya kwesokudla, lembule indawo evulekile. Uketshezi ludlula ebholeni ngembobo enkulu. Lapho ukugeleza kuyeka, ibhola libuyela emuva kwesobunxele.
Lokho “kuqhuma” umehluko oyinhloko kusuka kupayipi elivamile. Ngaphandle kwalo, ibhola alikwazanga ukuphuma endleleni.
I-Ball Check Valve vs. Ezinye Izinhlobo Ze-Valve
Ngivame ukubona abantu bedidanisa ama-valve okuhlola ibhola namanye ama-valve. Ake sikulungise lokho.
I-Ball Check Valve vs. I-Swing Check Valve
I-valve yokuhlola i-swing isebenzisa idiski ene-hinged evulekayo futhi ivalwe. Isebenza kahle emanzini ahlanzekile noma emoyeni, kodwa i-hinge ingagcwala ngenxa yemfucumfucu. Ama-valve okuhlola ibhola awanazo izihibe. Uma kungena i-grit encane, ibhola livame ukuligingqa noma ukulibamba phansi kwe-cavity ngaphandle kokulahlekelwa uphawu.
Omunye umehluko: ukuhlolwa kokujikijela kudinga ukugeleza okuphezulu ukuze kuhlale kuvulekile. Uma ukugeleza kuphansi, idiski inganyakaza, okubangela ukuguguleka. Ivalvu yokuhlola ibhola ivuleka ngokugcwele ngisho noma ukugeleza kuphansi ngoba ibhola liyagingqika ngokuphelele. Kodwa-ke, ukuhlolwa kokujikijela ngokuvamile kunokwehla kwengcindezi okuphansi uma livuliwe ngokuphelele. Ngakho-ke uma uhambisa umthamo omkhulu woketshezi oluhlanzekile, ukuhlolwa kokujikijela kungase kube ngcono kakhulu. Uma ukugeleza kungcolile noma kungahlali isikhathi eside, ukuhlolwa kwebhola kuyaphumelela.
I-Ball Check Valve vs. I-Ball Valve Ejwayelekile
Lokhu kuyindida evamile. I-valve yebhola evamile (lena enesibambo sokujika ikota) akuyona i-valve yokuhlola. Iyi-valve yokuvala. Uphendula isibambo ukuze uvumelanise imbobo ebholeni ne-pipe bore. Ihlala lapho uyibeka khona. Ayivali ngokuzenzakalelayo lapho ukugeleza kubuyela emuva.
Ivalvu yokuhlola ibhola ayinaso isibambo. Iyazenzakalela. Awukwazi “ukuyivula” noma “ukuyivala” ngesandla. Ngakho-ke uma othile ecela “ivalvu yebhola” ohlelweni lokuvimbela ukugeleza kwamanzi emuva, qiniseka ukuthi empeleni usho ivalvu yokuhlola ibhola. Ngaphandle kwalokho, uzoba nesiphithiphithi esikhulu lapho ipompo ima.
Izicelo Eziyinhloko Zama-Ball Check Valve
Ama-valve okuhlola ibhola abonakala ezindaweni lapho ukuthembeka nokubekezelela ukungcola kubaluleke kakhulu kunokusebenza kahle ngokuphelele.
Amakhono e-Valve angabuyisi
Njengevalvu engabuyisi, ukuhlolwa kwebhola kuhamba phambili emigqeni yokukhipha iphampu. Cabanga ngamaphampu e-sump, izinhlelo zokunisela, kanye namaphampu okulinganisa amakhemikhali. Kuvimbela uketshezi olupompelwe ukuthi lungangeni ethangini lapho iphampu ivala. Lokho kusho ukuthi iphampu akudingeki iphinde ifake i-prime njalo lapho iqala.
Sekungamashumi eminyaka ngibona ukuhlolwa kwamabhola kusetshenziswa kumaphampu e-bilge ezikebheni. Amanzi anosawoti, udoti, ukusebenza ngezikhathi ezithile - ibhola elincane lerabha liyaqhubeka nokusebenza.
Izicelo Zokuhlola Amavalvu Aphezulu
Uma ingcindezi idlula i-1,000 psi, ama-check valve amaningi ayahluleka. Ama-poppet valve agcwele intwasahlobo angakhathala. Ama-swing checks angashaya ngamandla. Kodwa i-ball check valve entantayo - ikakhulukazi ngebhola lensimbi nesihlalo esiqinile - ingaphatha ingcindezi ephezulu kakhulu. Ibhola lisabalalisa amandla okuvala ngokulinganayo eduze kwesihlalo, ngokungafani ne-poppet egxilisa ingcindezi endandatho encane.
Uzothola ama-valve okuhlola ibhola anomfutho ophezulu ezinhlelweni ze-hydraulic, ama-washer anomfutho ophezulu, kanye nemigqa yokukhipha i-compressor ephindaphindayo. Amanye anesilinganiso esifinyelela ku-10,000 psi.
I-Floating Ball Check Valve – Ukubuka Konke Okuningiliziwe
Igama elithi “i-floating ball check valve” lizwakala lihle, kodwa lisho ukuthi ibhola aliqondiswa yisiqu noma ikheji. Likhululekile ukuhamba eceleni futhi lijikeleze. Kungani lokho kubalulekile? Ngoba ibhola elintantayo lingajikeleza. Njengoba uketshezi ludlula, ibhola lijikeleza ngokungahleliwe. Lokho kusabalalisa ukuguguleka ngokulinganayo ebusweni balo. Ibhola eliqondisiwe, ngokuphambene nalokho, liyaguguleka endaweni efanayo futhi ekugcineni liyavuza.
Imiklamo yamabhola antantayo nayo iyabekezelela ukungalungi kahle. Uma umzimba wevalvu uphambuka kancane ngenxa yokushisa noma ama-flange aqiniswe kakhulu, ibhola liyaqhubeka lithola isihlalo. I-poppet eqinile ngeke ikwazi.
Inkinga eyodwa: amabhola antantayo ngezinye izikhathi “angakhuluma” ngezinga eliphansi kakhulu lokugeleza uma ibhola ligxuma phakathi kwesihlalo nelima. Kodwa empeleni, lokho akuvamile ngaphandle kokuthi uketshezi lucishe lungashintshi.
Izinzuzo Zokusebenzisa Ama-Ball Check Valve
Ake ngifingqe ukuthi kungani onjiniyela abaningi kangaka befinyelela i-valve yokuhlola ibhola kuqala.
Ukuvalwa okulula, okuthembekile– Izingxenye ezimbalwa ezihambayo zisho ukwehluleka okuncane. Akukho ziphethu ezizophuka. Akukho zihibe zokugqwala.
Ukunakekelwa okuphansi– Uma ivalvu yokuhlola ibhola igcina igugile (ngemva kweminyaka), uvame ukushintsha ibhola nesihlalo. Eminye imiklamo ikuvumela ukuthi wenze lokho ngaphandle kokususa ivalvu emgqeni.
Ifanele uketshezi oluqinile noma olungcolile– Ibhola lingasunduza eceleni izinto ezincane eziqinile. Ukuhlolwa kokujikijela kungavimbeka. Ukuhlolwa kwe-diaphragm kungadabuka.
Idizayini encane– Ukuhlolwa kwebhola kuvame ukuba kufushane kunokuhlolwa kwe-swing. Lokho kubalulekile kuma-tight pump skids noma ekusetshenzisweni kwe-marine.
Into eyodwa okufanele uyiqaphele: ama-valve okuhlola ibhola adinga ukugeleza okuncane ukuze ahlale evulekile. Uma ukugeleza kuphansi kakhulu (ama-trickle), ibhola lingase lingaphakami ngokugcwele, futhi uzothola imingcele ethile. Kodwa ezinhlotsheni eziningi zezimboni kanye nezindawo zikamasipala, lokho akuyona inkinga.
Isiphetho: Ukukhetha i-Ball Check Valve Efanele Yesistimu Yakho
Ngakho-ke, ukhetha kanjani okulungile?
Okokuqala, bheka uketshezi lwakho. Amanzi ahlanzekile? Cishe noma yiluphi uhlobo luyasebenza. Amanzi anosawoti noma amakhemikhali? Ingabe ipulasitiki noma insimbi engagqwali. Ama-slurries? Sebenzisa ibhola elimbozwe ngerabha kanye nesihlalo esithambile.
Okwesibili, hlola ukucindezela kwakho kanye nokushisa. Amabhola e-PVC ajwayelekile ahlola amazinga aphezulu kakhulu okushisa angaba ngu-140°F kanye no-150 psi. Ezensimbi ziphakeme kakhulu.
Okwesithathu, cabanga ngokuqondiswa. Ipayipi elivundlile elinokuhamba kwesobunxele kuya kwesokudla? Liphelele. Liqondile elinokuhamba kwenyuka? Lihle futhi. Liqondile elinokuhamba kwehla? Ungakwenzi lokho - ibhola lizowela esihlalweni lihlale livaliwe.
Okokugcina, cabanga ngengcindezi yokuqhekeka. Uma uhlelo lwakho lunengcindezi ephansi kakhulu yokuhlukanisa, funa ibhola elilula (ipulasitiki) noma umklamo osizwa yintwasahlobo.
Ivalvu yokuhlola ibhola akuyona impendulo efanele yazo zonke izinkinga zokugeleza kwamanzi emuva. Kodwa kumaphampu amaningi, amapayipi okudonsa amanzi, kanye nemigqa yamanzi angcolile, inzima kakhulu ezohlala isikhathi eside kunezinye izinhlelo. Futhi uma uyifaka, cishe uzokhohlwa ukuthi ikhona ngisho nalapho – okuyilokho kanye okufunayo kuvalvu yokuhlola.
