i-ductile iron double door check valve amanani

Amathayi angenawo amashubhu angcono kakhulu kunamanye amathayi, kodwa lokhu akusho ukuthi aphelele. Ngezinye izikhathi, ukugcina nje isondo elingena-tube emoyeni kungaba inselele, futhi ukuxilonga inkinga (ingasaphathwa ukulungisa inkinga) kungase kukhungathekise. Uma uzithola ugqolozele amathayi aphantshile egaraji bese uvungazela ukuthi "kungani" kaningi, nanka amathiphu angakusiza ukuthi ugiqe futhi. Lesi sihloko ngeke sihlanganise ukufakwa kwamathayi angenalutho; sicabanga ukuthi amathayi afakwe ngempumelelo, kodwa ngeke agcine umoya isikhathi esingaphezu kosuku noma ngaphezulu. Cha, asikagubhi okwamanje, kodwa ngokusivumela ukuthi sikhiphe ingxenye eputshuziwe, lokhu kuzosisondeza emgomweni wethu. Gcwalisa ibhodlela lesifutho ngamanzi kanye nensipho yezitsha, nanoma iyiphi insipho eyenza amabhamuza. Okulandelayo, faka umoya isondo libe ngu-30 psi. Isifutho esisodwa noma vele uthele amanzi anensipho eduze kwamasondo namarimu. Naka noma yiziphi izindawo lapho amabhamuza avela khona. Uma isondo ngokwalo livuza, ngokuvamile kulula ukulixazulula. Qinisekisa ukuthi kune-sealant eyanele ethayini bese uhambahamba kuze kube yilapho i-sealant ibhoboza. I-puncture ingase izuze ukubhoboza okukhulu. Uma kukhona ukuvuza kodonga oluseceleni, ngokuvamile kungcono ukulishintsha isondo. Ingahle ifakwe nezimagqabhagqabha, noma uma unenhlanhla ngempela, ungayixhuma, kodwa ngokuhlangenwe nakho kwami, ukulungiswa kodonga oluseceleni akuvamile ukuhlala isikhathi eside. Nakuba kuyivelakancane, amathayi athile ayaziwa ukuthi amunca noma afakwe isivalo esimanzi. Uma seyengezwe ekuqaleni, izimbobo ezincane zerabha yesondo zizogcwaliswa nge-sealant, ngakho-ke kungase kudingeke wengeze uketshezi olwengeziwe ukuze wenze uketshezi olulahlekile. Uma isondo lisavuza ukusuka ku-tread noma udonga oluseceleni ezindaweni eziningi ngaphandle kokumbozwa kahle kwe-sealant futhi lingekho ukubhoboza, ungase udinge ukuthintana nesitolo sakho sendawo samabhayisikili noma umkhiqizi wamathayi ukuze ubone ukuthi isondo kufanele lishintshwe yini. Hlola ukuze uqiniseke ukuthi awekho ama-depression odongeni lwamarimu. Uma kunjalo, amathayi akho ngeke avalwe. Uma uthola ukuthi unqenqema lugobile kancane noma lucwile, kungenzeka ukuthi uluqondise ukuze luqukathe umoya. Ngokusho kukaGerow, "Amabhodi ambalwa amancane, i-vise nesando kuzokwenza uqalise." Ngisho noma udonga lwerimu lungaboshiwe kakhulu noma lukhubazekile, kungase kube negebe elincane phakathi kobuhlalu besondo nomphetho, okungavuza umoya. Qinisekisa ukuthi kune-sealant eyanele ethayini, bese ulibeka livundlile bese ulitshekisa ukuze uketshezi luqoqekele engxenyeni yomugqa lapho kubonakala khona amagwebu. Gcoba kancane isondo isikhathi esingangomzuzu ukuze i-sealant iqedele umsebenzi wayo. Kwezinye izimo, ukuxhumeka kwesondo-rim kungase kube buthakathaka ngenxa yokuqoqwa kwe-sealant endala. UGro uthe: "Amathayi amadala azonqwabelanisa i-sealant eyomile neqinile ebuhlalu, okuzokwenza kube nesikhala phakathi kwerimu nenjoloba, kubangele ukuvuza komoya." "Lapho ufaka isondo elike lafakwa ngaphambili, sicela wenze isiqiniseko sokuthi Khipha isivalo esomile ngangokunokwenzeka kubuhlalu." Ngezinye izikhathi, ubuhlalu bungase bungavikeleki ngokugcwele emgqeni. Zama ukupompa amathayi kumfutho omkhulu. Umsindo omkhulu ozowuzwa wukuthi ubuhlalu bukhona. Uma ungawuzwa lo msindo ngesikhathi uqala ukufaka isondo, mhlawumbe inkinga. Ngemva kokugcwalisa isheke elingenhla, zama ukufaka insipho isondo futhi futhi uhlole iphuzu elifanayo ukuze ubone ukuthi ukulungiswa kuphumelele. Ngokuhlangenwe nakho kwami, ngokuhamba kwesikhathi, ukuvuza kwe-valve ngokuvamile kuyimbangela yokulahlekelwa kwengcindezi yomoya. Uma amanzi anensipho ethola amabhamuza kuvalvu, sekuyisikhathi sokuqhubeka nophenyo. Okokuqala, hlola izinto ezilula: ingabe umnyombo uqinisiwe? Ingabe izikulufu zokungena zikhululekile noma zigobile? Ithuluzi le-spool elizinikele lisiza ukuqinisa kahle, uma iminwe yakho ingaqinile ngokwanele ukuze ifake i-inlet plunger, amapuleti ekhala yenaliti angakwazi ukwenza umsebenzi. Vele uqiniseke ukuthi awuqinisi kakhulu futhi ulimaze i-valve, noma uyiqinise ukuze ungakwazi ukwengeza umoya ngokuhamba kwesikhathi. Uma noma iyiphi ingxenye ye-valve igobile noma iqhekekile, ungazami ukuyilungisa; sekuyisikhathi sokuyishintsha. Uma amabhamuza ensipho akheka ngaphansi kwevalvu, kungenzeka ukuthi ingaxhunywanga kahle nerimu. Amavalvu amaningi anamantongomane ngezansi ukuze afinye ivalve kurimu. Yiqinise ngokusemandleni akho ngeminwe yakho, futhi uma kunesidingo, yiphendule kancane ngesikrufu. Vele uqiniseke ukuthi ugwema ukuqinisa ngokweqile, njengoba lokhu kungase kulimaze i-rim, ikakhulukazi i-carbon fibre rim, futhi esimweni sokubhoboza, kungase kudingeke ukwazi ukususa inati ethrekhi. Okulandelayo, hlola i-valve ukusuka komunye umkhawulo, okusho ukukhipha isondo emgqeni. Ama-valve amaningi ane-gasket yerabha ethambile eyenza uphawu eduze kwembobo ye-valve onqenqemeni, ngakho hlola ukuze uqiniseke ukuthi i-valve ihlezi kahle esiteshini se-rim. Ungakwazi futhi ukwengeza itheyiphu encane ye-Teflon eduze kwe-valve ukuze uvale izinto. Ngezinye izikhathi, i-sealant ivala izikhala ezincane ezizungeze i-valve. Uma uthola ukuvuza komoya emgwaqeni, zama ukuzungezisa nokunyakazisa isondo ukuze isivalo esiwuketshezi sifinyelele kuvalvu. Uma amagwebu akheka engonweni ekhulumayo, izindaba ezinhle ukuthi usuthole ukuvuza! Izindaba ezimbi ukuthi asikho isixazululo esisheshayo. Ngokuvamile, lokhu kusho ukuqinisa kabusha umugqa, noma okungenani ukulungisa itheyiphu. Uma itheyiphu ishwabene, idabukile noma ibhobokile, kungase kube imbangela yokuvuza. Lapho ufaka ubuhlalu, i-lever yesondo ivame ukubhoboza itheyiphu, okubangela ukuthi itheyiphu ivuze umoya onqenqemeni. Kunezifundo eziningi eziku-inthanethi kumarimu angenawo ama-tubeless, kodwa ngokuvamile, inhloso yalokhu ukwenza i-rim ihlanzeke futhi yome ngangokunokwenzeka, bese wenza okunye ukusonga. Qaphela noma yiziphi izikhala lapho umoya ungase uvuze khona, futhi gcina itheyiphu isicaba futhi inyakaze ukuze ugweme amabhamuza noma amaphakethe. Ngezinye izikhathi, isondo lingase libe ukuvuza okunyonyobayo. Zimpompe futhi zizohlala ziqinile egaraji amasonto, kodwa uma usushayela endaweni yokupaka noma ujika, zizothamba. Ukhuhla ngensipho futhi awuboni noma yimaphi amagwebu. Eqinisweni, lokhu kuye kwenzeka izikhathi eziningana ezinyangeni ezimbalwa ezedlule. Lokhu ngokuvamile kungenxa yokuthi i-incision encane izovuleka kuphela uma kunento esindayo ethayini noma isondo liphonswa kumfutho ophakeme. Egaraji lakho, ungazama ukulingisa umphumela wokugibela ngokukhuphula ingcindezi ngaphezu kwengcindezi evamile yokushayela noma ngokuguqula isondo ngesandla futhi ubheke amabhamuza omoya njengoba isondo likhasa. UGerow waphawula: "Amanye amathayi adinga ukugitsheliswa ngokushesha ngemva kokufakwa ukuze kugcinwe umoya. Ngemva kokukhuphuka isikhashana emzileni, isondo elisha elingeke liphele egaraji lingase libe yisinqumo esihle." Uma ukuvuza okucashile kutholakele, ukuletha isivalo endaweni efanele kungaxazulula inkinga, nakuba kungase kube ngcono ukusebenzisa ipulaki. Ekuhlaziyeni kokugcina, i-tubeless mountain bike tire system ilula kakhulu futhi ingahlakazeka kuphela ezindaweni eziningi emoyeni. Zicabange uwumoya ethayini futhi ufuna indlela yokuphuma. uzokwenzani? Lona umqondo owudingayo ukuze uxazulule le puzzle. Ngisanda kushintsha isondo le-WTB. Nakuba isondo lingagqokile ikakhulukazi, isondo liyavuza ngodonga oluseceleni futhi linyathele. Lapho amathayi esemasha, ngabona nokukhala okuvamile. Uchwepheshe endaweni yangakithi esitolo samabhayisikili wathi amathayi e-WTB adume ngalokhu, kodwa angazi noma lokhu kuyiqiniso yini. Kuyasabisa ngempela lokho. Egaraji (ijimu lapho ikhiyiwe), hlola okuphakelayo kwezindaba zami futhi ufunde ukuphawula kwakho lapho ngibheka i-WTB Trail Boss engiyifake ezinsukwini ezimbili ezedlule. I-spin test yenziwe izolo ekuseni, kwatholakala ukuthi amathayi amasha ayesambozwe amaconsi amanzi, kuyilapho amathayi angemuva omile! Isondo lavuza i-sealant odongeni oluseceleni njengesisefo! eyigugu! Nakuba kubonakala ukugcina ingcindezi. isihloko esihle. I-Gorilla Tape ibisetshenziswa esikhathini esidlule. Kuhle, kuze kube yilapho udinga ukususa amathayi. Itheyiphu ijiyile futhi yenziwe ngendlela ehlukile. Ngaphezu kwalokho, nginesibonelo lapho i-tape yokunamathisela ibonakala isabela nge-sealant futhi "i-welded" itheyipu ebuhlalu besondo. Isondo kufanele lisikwe emgqeni. I-Toolstation 50mm itheyiphu kagesi kanye ne-Effetto Mariposa Caffelatex esanda kusetshenziswa. Kubonakala kuyasebenza. Ngamisa isondo elinamafutha angenashubhu. Lapho kufanele ngibuyisele amathayi, okokuqala ngisebenzisa i-Gorilla Tape, imiphumela yayimaphakathi kodwa ingcolile. Okwesibili ngasebenzisa imichilo ye-latex ye-FATTIE STRIPPERS futhi ngathola imiphumela emangalisayo. Uma usebenzisa insipho ukuze uvale amathayi njengoba kunconyiwe, avala kahle kangangokuthi ekuqaleni angizange ngisebenzise i-sealant futhi ngiyigcina igcwele umoya isonto lonke. Ngabe sengifaka ama-ounces ama-3 kuphela emathayini angama-26×4.8 futhi ngagibela inyanga. Awukho umoya owengeziwe. ezithakazelisayo. Ngibe nenhlanhla yokusebenzisa i-Gorilla Tape esikhundleni se-rim tape ezinikele eyayixega ngokuhamba kwesikhathi. Ekugcineni yonke i-tape izodinga ukushintshwa. Ngenhlanhla, ngine-roll ye-Gorilla tape eduze kwami. Sawubona Jeff, ngithenge i-Giant Trance e-mtb + 1pro ngoMashi 2019. Ifakwe amathayi e-Maxiss angenamashubhu, kodwa anamashubhu angaphakathi. Ngaleso sikhathi, amakhilomitha angu-6000 aqedwa ngesikhathi esisodwa. Cishe u-60% wemizila yezintaba yaseNew Zealand. Ngicabange ngokungasebenzisi amashubhu e-electron 100%, kodwa manje nginemibono emibili. Yiziphi izinzuzo/ububi balezi zinketho ezimbili? Ngokubona kwami, indlela engeyona intubation inezinkinga eziningi kunezinye izindlela. Halala Jeff, angikwazi ukuzwa ingcindezi eyanele kwikhwalithi yolayini be-latex, inwebeka onqenqemeni ukuze yenze ukulingana okumunca okuhlanzekile, okungasindi, okungenazinti.
