Inkqubo yokusebenza kwevalve ikwayinkqubo yokuhlola nokuphatha ivalve. Nangona kunjalo, le miba ilandelayo kufuneka ithathelwe ingqalelo xa usebenzisa isivalo.
①Ivalve yobushushu obuphezulu. Xa iqondo lokushisa liphakama ngaphezu kwe-200 ° C, iibholiti ziyafudumala kwaye zide, kube lula ukwenza isitywina se-valve sikhululeke. Ngeli xesha, iibholiti kufuneka "zitshise-zitshise", kwaye akufanelekanga ukwenza ukuqina okutshisa kwindawo evaliweyo ngokupheleleyo, ukwenzela ukuba ugweme i-valve stem ekubeni ifile kwaye kunzima ukuyivula kamva. .
②Ngexesha lonyaka xa ubushushu bungaphantsi kwe-0℃, nikela ingqalelo ekuvuleni iplagi yesitulo sevalvu yeevalvu ezimisa umphunga kunye namanzi ukususa amanzi ajiyileyo kunye namanzi aqokelelweyo, ukunqanda ukukhenkceza kunye nokuqhekeka kwevalve. Nika ingqalelo ekugcinweni kobushushu kwiivalvu ezingakwaziyo ukuphelisa ukuqokelelwa kwamanzi kunye neevalvu ezisebenza rhoqo.
③ Idlala lokupakisha akufuneki licinezeleke kakhulu, kwaye ukusebenza okuguquguqukayo kwesiqu sevalve kufuneka kuphumelele (akulunganga ukucinga ukuba ukuqiniswa kwedlala lokupakisha, kungcono, kuyakukhawulezisa ukuguga kwesiqu sevalve kwaye kwandiswe. itorque yokusebenza). Ngaphantsi kwemeko yokungabikho kwemilinganiselo yokukhusela, ukupakishwa akukwazi ukutshintshwa okanye ukongeza phantsi koxinzelelo.
④Ngexesha lotyando, izinto ezingaqhelekanga ezifunyenwe ngokumamela, ukujoja, ukubona, ukubamba, njl.
⑤ Umsebenzisi kufuneka abe nencwadi ekhethekileyo yelog okanye incwadi yokurekhoda, kwaye ubeke ingqalelo ekurekhodeni ukusebenza kweevalvu ezahlukeneyo, ngakumbi ezinye iivalve ezibalulekileyo, ubushushu obuphezulu kunye noxinzelelo oluphezulu kunye neevalvu ezikhethekileyo, kubandakanywa nezixhobo zabo zokuhambisa. Kufuneka kuqatshelwe ukungaphumeleli, unyango, iindawo ezitshintshileyo, njl., ezi zinto zibalulekile kumqhubi ngokwawo, abasebenzi bokulungisa kunye nomenzi. Ukuseka ilogi ekhethekileyo kunye noxanduva olucacileyo, olunenzuzo ukomeleza ulawulo.
