Ngaba uyazi indlela eqhelekileyo yokwahlulahlula iivalvu zebhabhathane zombane?

Iivalvu zebhabhathane zombaneluhlobo lwevalvu yombane kunye nevalvu yokulawula yombane. Iindlela eziphambili zokudibanisa umbaneiivalvu zebhabhathanezezi: uhlobo lweflange kunye nohlobo lwe-wafer; iindlela eziphambili zokutywinaiivalvu zebhabhathane zombanezezi: ukutywinwa kwerabha kunye nokutywinwa kwesinyithi.

Umbaneivalvu yebhabhathaneilawula ukuvulwa nokuvalwa kwevalvu yebhabhathane ngokusebenzisa imiqondiso yamandla. Le mveliso ingasetyenziswa njengevalvu yokuvala, ivalvu yokulawula kunye nevalvu yokujonga kwiinkqubo zemibhobho. Ixhotyiswe ngesixhobo sokulawula ngesandla. Kwimeko yokucima kombane, ingasetyenziswa ngesandla okwethutyana ukuze ithintele ukuchaphazela ukusetyenziswa kwayo.

Uhlulo ngokwemo yesakhiwo

(1) Isitywino esiphakathi

Ingatshatangaivalvu yebhabhathane yombane etyhidiweyo.

(3)Ivalvu yebhabhathane yombane ephindwe kabini engaqhelekanga.

(4) Ivalvu yebhabhathane yombane evalwe nge-offset ezintathu.

2. Uhlu ngokwesitywino sezinto zomphezulu

(1) Isibini sokutywina esithambileyo senziwe ngezinto ezithambileyo ezingezizo zesinyithi nxamnye nezinto ezithambileyo ezingezizo zesinyithi. Isibini sokutywina senziwe ngezinto eziqinileyo zesinyithi nxamnye nezinto ezithambileyo ezingezizo zesinyithi.

(2) Ivalvu yebhabhathane yombane etywiniweyo yesinyithi. Isibini sokutywina senziwe ngezinto eziqinileyo zesinyithi ezichasene nezinto eziqinileyo zesinyithi.

3. Uhlu ngokwendlela yokutywina

(1) Ukutywinwa okunyanzelekileyo: Ivalvu yebhabhathane yombane yokutywinwa nge-elastic. Uxinzelelo oluthile lokutywinwa lwenziwa yipleyiti yevalvu ecinezela isihlalo sevalvu xa ivalvu yombane ivaliwe, kunye nokuthamba kwesihlalo sevalvu okanye ipleyiti yevalvu. Ivalvu yebhabhathane yombane yokutywinwa nge-torque yangaphandle, uxinzelelo oluthile lokutywinwa lwenziwa yitorvu esetyenziswa kwishafti yevalvu.

(2) Ivalvu yebhabhathane yombane yokutywina ecinezelweyo: Uxinzelelo oluthile lokutywina lwenziwa ngokucinezela into yokutywina elastiki kwisihlalo sevalvu okanye kwipleyiti yevalvu.

(3) Ivalvu yebhabhathane yombane yokutywina ngokuzenzekelayo: Uxinzelelo oluthile lokutywina lwenziwa ngokuzenzekelayo luxinzelelo oluphakathi.
