Ingxaki yevalvu yebhabhathane yerabha kukuba xa isetyenziselwa ukubhoboza, ukugoba kwesisu kuya kwenzeka ngenxa yokusetyenziswa ngendlela engafanelekanga, nto leyo ebangela ukuba isihlalo serabha sixobuke kwaye sonakale. Ngenxa yesi sizathu, iivalvu zebhabhathane ezivalwe ngesinyithi ziye zaphuhliswa kwihlabathi liphela, kwaye indawo yokugoba kwesisu iye yancitshiswa. Kwiminyaka yakutshanje, ilizwe lam liye laphuhliswa neevalvu zebhabhathane ezivalwe ngesinyithi. EJapan, iivalvu zebhabhathane ezimile okwekhombhini ezinokumelana nokugoba kwesisu, ukungcangcazela okuphantsi kunye nengxolo ephantsi nazo ziye zaphuhliswa kwiminyaka yakutshanje.
Ngokubanzi, ubomi besihlalo sokutywina ivalvu yebhabhathane yiminyaka eli-15-20 kwirabha kunye neminyaka engama-80-90 kwisinyithi phantsi kweemeko eziqhelekileyo. Nangona kunjalo, ukhetho oluchanekileyo luxhomekeke kwiimfuno zeemeko zokusebenza.
Ubudlelwane phakathi komgangatho wokuvula wevalvu yebhabhathane yokutywina intsimbi kunye nesantya sokuhamba ngokusisiseko siyatshintsha ngokuthe ngqo. Ukuba isetyenziselwa ukulawula ukuhamba, iimpawu zayo zokuhamba nazo zinxulumene ngokusondeleyo nokumelana nokuhamba kwepayipi. Umzekelo, kufakwe imibhobho emibini enobubanzi bevalvu efanayo kunye nefom, kodwa i-coefficient yokulahleka kwepayipi yahlukile, kwaye izinga lokuhamba kwevalvu nalo liya kwahluka kakhulu. Ukuba ivalvu ikwimeko enoluhlu olukhulu lwe-throttle, umva wepleyiti yevalvu uthambekele ekucasukeni, okunokonakalisa ivalvu. Ngokubanzi, isetyenziswa ngaphandle kwe-15°.
Xa ukulungiswa kwebhathane yentsimbi kukwindawo ephakathi, imo yokuvula eyenziwe ngumzimba wevalvu kunye nesiphelo esingaphambili seplate yebhathane iphakathi kwi-shaft yevalvu, kwaye amacala amabini enziwa ukuze kugqitywe iimeko ezahlukeneyo. Isiphelo esingaphambili seplate yebhathane kwelinye icala sihamba kwicala lamanzi aqukuqelayo, kwaye elinye icala libuyela umva. Ke ngoko, elinye icala lomzimba wevalvu kunye neplate yevalvu zenza ukuvulwa okufana nomlomo, kwaye elinye icala lifana nokuvulwa kwe-throttle. Icala le-nozzle linesantya sokuhamba ngokukhawuleza kakhulu kunecala le-throttle, kwaye ivalvu esecaleni le-throttle iya kuvelisa uxinzelelo olubi, izitywino zerabha zihlala ziwela.
I-torque yokusebenza yokulungiswa kwebhabhathane yentsimbi inexabiso elahlukileyo ngenxa yeendlela ezahlukeneyo zokuvula nokuvala kwevalvu. Ivalvu yebhabhathane ethe tye, ingakumbi ivalvu yebhabhathane enobubanzi obukhulu, ngenxa yobunzulu bamanzi, i-torque eveliswa ngumahluko phakathi kweentloko zamanzi eziphezulu nezisezantsi zeshaft yevalvu ayinakutyeshelwa. Ukongeza, xa kufakwa ingqiniba kwicala lokungena levalvu, kwakheka ukuhamba kwe-bias kwaye i-torque iya kwanda. Xa ivalvu ikwindawo ephakathi yokuvula, indlela yokusebenza kufuneka izivale ngokwayo ngenxa yesenzo se-torque yokuhamba kwamanzi.

INortech ngomnye wabavelisi beevalvu zoshishino abaphambili eTshayina abanesiqinisekiso somgangatho se-ISO9001.
