Njengoko sonke sisazi, inxalenye ekuphela kwayo yesithuthi edibana nomhlaba yitayara. Amatayara eneneni enziwe ngezinto ezininzi ezifunekayo ukuze itayara isebenze kakuhle kwaye ivumele imoto ukuba ifikelele kwinqanaba layo. Amatayara abalulekile ekusebenzeni kwesithuthi, ekuziveni, ekuphatheni, kwaye okona kubaluleke kakhulu, kukhuseleko. Ayizo kuphela amatayara erabha aqinisekisa ukhuseleko ngexesha lokuqhuba, kodwa ivalvu yetayara ikwayinxalenye ebalulekileyo kwitayara.
Yintoni iValve yeTyre?
Ivalvu yetayara sisixhobo somzimba wevalvu esizimeleyo, xa sivuliwe, sivumela umoya ukuba ungene kwindawo yetayara okanye ityhubhu engenamibhobho, size sivale ngokuzenzekelayo kwaye sivale ukuze kudalwe uxinzelelo lomoya ukuthintela umoya ukuba ungaphumi kwitayara okanye ityhubhu. Ngaphandle kwamatayara aqinileyo, zonke ezinye iitayara okanye iityhubhu zangaphakathi ekufuneka zivuthelwe kufuneka zivuthelwe ngesi sixhobo.
Zingaphi Iintlobo Zevalvu Yethayara?
Ukuhlelwa kweevalvu zamatayara kuxhomekeke ekubeni zeziphi izinto ezihlelwe ngokwahlukileyo. Zingahlelwa ngokwemodeli esetyenzisiweyo, okanye zingahlelwa ngokwezinto ezisetyenzisiweyo kwivalvu. Phantsi kwemigangatho eyahlukeneyo, ukuhlelwa nako kwahlukile. Oku kulandelayo kunokuhlelwa ngokwendlela yokuhlanganiswa kwaye kunokwahlulwahlulwa ngokwahlukeneyoukufakwa kwerabhakwayei-clamp yesinyithi enoxinzelelo oluphezulu.
Iivalvu zeRubber Snap-In ezingenatyhubhu
Ivalvu yerabha engenazityhubhu inoxinzelelo oluphezulu lokunyuka kwamatayara abandayo oluyi-65psi kwaye yenzelwe ukusetyenziswa kwiimoto, iilori ezikhaphukhaphu kunye neetreyila ezikhaphukhaphu. Iivalvu zerabha ezikhaphukhaphu zingasetyenziselwa ukufaka imingxunya enobubanzi obuyi-0.453" okanye i-0.625" kumphetho, kwaye ziyafumaneka ngobude obuqala kwi-7/8" ukuya kwi-2-1/2". Ngokwenyani, ivalvu iza nesiciko seplastiki njengomgangatho, kodwa inokwenziwa ngokwezifiso ngesiciko se-chrome okanye isigqubuthelo sobhedu ukuze ihambelane nenkangeleko yevili.
Iivalvu zeClamp-In zeMetal eziXinzelelwe nguMbane
Ivalvu yentsimbi exineneyo enoxinzelelo oluphezulu ingangena phantse kuyo nayiphi na imodeli yemoto, kwaye sicebisa iivalvu zesinyithi kwiimoto ezisebenzayo kunye nezithuthi ezinokuqhutywa ngamandla ngesantya esingaphezulu kwe-130 mph. Ivalvu yentsimbi exineneyo ivala ivili nge-gasket yerabha ngelixa iqinisa i-retaining nut. Ngelixa uyilo kunye noyilo lweevalvu zentsimbi eziqhotyoshelwayo zinokubangela ukuba i-retaining nut ifihlwe ngaphakathi kwevili okanye ibonakale ngaphandle, ezo zine-retaining nut ngaphandle zibonelela ngenzuzo esebenzayo yokuvumela i-retaining nut ukuba ihlolwe kwaye ilungiswe ngaphandle kokususa ukuqina kwetayara kwivili. Iivalvu zentsimbi exineneyo zivumela uxinzelelo oluphezulu lokusebenza lwe-200 psi kwaye zingasetyenziselwa ukufaka imingxuma ye-0.453" okanye i-0.625" rim, kunye nezicelo ezikhethekileyo ezifana nemingxuma ye-6mm (.236") okanye i-8mm (.315").
Ungawubona njani umgangatho wevalvu yethayi?
Kwivalvu yerabha, umgangatho ohambelanayo wezinto ezahlukeneyo nawo wahlukile. Ivalvu yenziwe kakhulu ngerabha, isiqu sevalvu kunye nesiseko sevalvu. Phakathi kweerabha eziqhelekileyo kukho irabha yendalo kunye nerabha ye-EPDM. Izinto zesiqu sevalvu ziyafumaneka kwiindlela zobhedu kunye ne-aluminium. Isiseko sevalvu sidla ngokwenziwa ngesiseko sebrass, kodwa ezinye iimarike zengingqi zikhetha ukusebenzisa isiseko se-zinc kuba ixabiso lesiseko se-zinc liphantsi kakhulu. Ngokubanzi, kwiivalvu ezikumgangatho ophezulu, sicebisa ukusetyenziswa kwesiseko sebrass kunye nesiseko sebrass.
Ngaba kukho umahluko phakathi kwerabha yendalo kunye nerabha ye-EPMD?
Okokuqala, irabha yendalo ifunyanwa kwizityalo ezifana nemithi yerabha, ngelixa irabha ye-EPDM yenziwe ngokwenziwa; iimveliso zerabha ze-EPDM ziba lukhuni kwaye ziqhekeke emva kokwaluphala, ngelixa iimveliso zerabha yendalo zithambile kwaye zinamathela emva kokwaluphala.
Ukusebenza kwerabha ye-EPDM yokuguga kobushushu kungcono kunerabha yendalo; ukusebenza kobushushu kunye nokusebenza kokulwa nokugqwala kwerabha ye-EPDM kubhetele kunerabha yendalo; ukusebenza kwamanzi angangeni manzi, ashushu kakhulu kunye nomphunga wamanzi kwerabha ye-EPDM Kungcono kakhulu kunerabha yendalo, ukusebenza okugqwesileyo kukumelana nomphunga oxinzelelo oluphezulu, kungcono kunerabha ye-fluorine; enye inzuzo kukuba irabha ye-EPDM inomlinganiselo omkhulu wokuzalisa, onokuzaliswa ngombala omnyama kunye nezizalisi ezahlukeneyo zekhabhoni. Ayichaphazeli iipropati ezininzi zemveliso njalo njalo.
Ngoko ke, xa idibene nohlalutyo olungentla, indibaniselwano yezinto esizicebisayo zevalvu esemgangathweni ophezulu yileIrabha ye-EPDM + Isiqu sebrass + Umbindi webrass.
