Njengoba sonke sazi, ingxenye kuphela yemoto ethinta umhlabathi yithayi. Amathayi empeleni akhiwe yizingxenye eziningi ezidingekayo ukuze ithayi lisebenze kahle futhi livumele imoto ukuthi ifinyelele amandla ayo. Amathayi abalulekile ekusebenzeni kwemoto, ekuzizweni kwayo, ekuphatheni kwayo, futhi okubaluleke kakhulu, ekuphepheni kwayo. Akuwona amathayi enjoloba kuphela aqinisekisa ukuphepha ngesikhathi sokushayela, kodwa nevalvu yethayi nayo iyingxenye ebalulekile ethayini.
Iyini iValvu Yethayi?
Ivalvu yethayi iyithuluzi lomzimba wevalvu elizimele, lapho livulwa, elivumela umoya ukuthi ungene esikhaleni sethayi noma ithubhu elingenamapayipi, bese livala ngokuzenzakalelayo futhi livale ukuze kudalwe umfutho womoya ukuvimbela umoya ukuthi ungaphumi ethayini noma ithubhu. Ngaphandle kwamathayi aqinile, wonke amanye amathayi noma amathubhu angaphakathi okumele afakwe umoya adinga ukufuthwa ngale divayisi.
Zingaki Izitayela Zevalvu Yethayi?
Ukuhlukaniswa kwamavalvu amathayi kuncike ekutheni yiziphi izici ezihlukaniswe. Kungahlukaniswa kusukela kumodeli esetshenzisiwe, noma kungahlukaniswa kusukela ezintweni zevalvu. Ngaphansi kwezindinganiso ezahlukene, ukuhlukaniswa nakho kuhlukile. Okulandelayo kungahlukaniswa ngokwendlela yokuhlanganiswa futhi kungahlukaniswa kubeukufakwa kwerabhafuthii-clamp yensimbi enomfutho ophezulu.
Amavalvu Okungena Ngenjoloba Angenazimbobo
Ivalvu yerabha engenamapayipi inomfutho ophezulu wokushisa amathayi abandayo ongu-65psi futhi yenzelwe ukusetshenziswa ezimotweni, amaloli alula kanye nama-trailer alula. Amavalvu erabha angasetshenziswa ukufaka izimbobo ezinobubanzi obungu-0.453" noma u-0.625" erimu, futhi atholakala ngobude obusukela ku-7/8" kuya ku-2-1/2". Ngokuyisisekelo, ivalvu iza nesembozo sepulasitiki njengenjwayelo, kodwa ingenziwa ngokwezifiso ngesembozo se-chrome noma isembozo sethusi ukuze ivumelane nokubukeka kwesondo.
Amavalvu Okufaka Insimbi Enomfutho Ophezulu
Ivalvu yensimbi ecindezela kakhulu ingangena cishe kunoma iyiphi imodeli yemoto, futhi sincoma amavalvu ensimbi ezimotweni ezisebenzayo nezimoto ezingase zishayelwe ngamandla ngesivinini esingaphezu kuka-130 mph. Ivalvu yensimbi ecindezelayo ivala isondo nge-gasket yerabha ngenkathi iqinisa inathi yokugcina. Ngenkathi ukwakheka kanye nesitayela samavalvu ensimbi angase abangele ukuthi inathi yokugcina ifihlwe ngaphakathi kwesondo noma ibonakale ngaphandle, lawo anenathi yokugcina ngaphandle anikeza inzuzo engokoqobo yokuvumela inathi yokugcina ukuthi ihlolwe futhi ilungiswe ngaphandle kokususa ukuqina kwethayi esondweni. Amavalvu ensimbi ecindezelayo avumela ingcindezi yokusebenza ephezulu engu-200 psi futhi angasetshenziswa ukufaka imigodi yamarimu angu-0.453" noma angu-0.625", kanye nezinhlelo ezikhethekile njengemigodi engu-6mm (.236") noma engu-8mm (.315").
Ungayibona Kanjani Ikhwalithi Yevalvu Yethayi?
Kwi-valve yerabha, ikhwalithi ehambisanayo yezinto ezahlukene nayo ihlukile. I-valve yakhiwe kakhulu ngerabha, isiqu se-valve kanye ne-core valve. Phakathi kwerabha ezivamile kukhona irabha yemvelo kanye nerabha ye-EPDM. Izinto zesiqu se-valve zitholakala ngezinketho zethusi kanye ne-aluminium. I-core valve ivame ukwenziwa nge-core yethusi, kodwa ezinye izimakethe zesifunda zikhetha ukusebenzisa i-core ye-zinc ngoba intengo ye-core ye-zinc ishibhile. Ngokuvamile, kuma-valve asezingeni eliphezulu, sincoma ukusetshenziswa kwe-core ye-stem yethusi kanye ne-core yethusi.
Ingabe Ukhona Umehluko Phakathi Kwerabha Yemvelo Nerabha Ye-EPMD?
Okokuqala, irabha yemvelo itholakala ezitshalweni ezifana nezihlahla zerabha, kuyilapho irabha ye-EPDM yenziwa ngokwenziwa; imikhiqizo zerabha ye-EPDM iba lukhuni futhi iqhekeke ngemva kokuguga, kuyilapho imikhiqizo zerabha yemvelo iba thambile futhi inamathela ngemva kokuguga.
Ukusebenza kokuguga kokushisa kwerabha ye-EPDM kungcono kunokwerabha yemvelo; ukusebenza kokushisa kanye nokusebenza kokulwa nokugqwala kwerabha ye-EPDM nakho kungcono kunokwerabha yemvelo; ukusebenza kwamanzi angangeni manzi, ashisayo kakhulu kanye nomhwamuko wamanzi kwerabha ye-EPDM Kungcono kakhulu kunerabha yemvelo, ukusebenza okuvelele kakhulu ukumelana nomusi ophakeme, kungcono ngisho kunerabha ye-fluorine; enye inzuzo ukuthi irabha ye-EPDM inenani elikhulu kakhulu lokugcwalisa, elingagcwaliswa ngama-carbon black ahlukahlukene kanye nama-filler. Ayithinti izakhiwo eziningi zomkhiqizo njalo njalo.
Ngakho-ke, kuhlanganiswe nokuhlaziywa okungenhla, inhlanganisela yezinto esizincomayo ze-valve esezingeni eliphezulu kakhuluIrabha ye-EPDM + Isiqu sethusi + Umongo wethusi.
