Likarolo tsa mantlha tsa setulo se senyehileng sa serurubele sa halofo ea shaft flange:
1. Moqapi oa li-half-shaft tse peli: Mokhoa oa ho bula le ho koala valve o tsitsitse haholoanyane, o fokotsa ho hanyetsa mokelikeli le ho ntlafatsa ho nepahala ha taolo ea phallo.
2. Setulo sa valve se nang le vulcanized: E entsoe ka thepa e khethehileng ea vulcanized, e na le ts'ebetso e ntle ea ho apara le ho tiisa ts'ebetso ea ho tiisa, ho netefatsa ts'ebetso e tsitsitseng ea nako e telele ea valve.
3. Khokahano ea Flange: Khokahano e tloaelehileng ea flange e sebelisoa ho nolofatsa khokahano le lisebelisoa tse ling mme e na le lits'ebetso tse fapaneng.
4. Li-actuator tse fapaneng: li-actuator tsa pneumatic, tsa motlakase kapa tsa letsoho li ka khethoa ho latela litlhoko tsa mosebedisi ho finyella litlhoko tse fapaneng tsa ts'ebetso.
5. Sebaka sa kopo: e sebelisoa haholo ho laola phallo ea liphaephe ka petroleum, indasteri ea lik'hemik'hale, metallurgy, phekolo ea metsi le masimo a mang.
6. Ts'ebetso ea ho tiisa: Ha valve e koetsoe, e ka tiisa ho tiisa ka ho feletseng le ho thibela ho tsoa ha metsi.
7. Tlhokomelo e bonolo: Sebopeho se bonolo, se bonolo ho se hlokomela le ho se lokisa, se fokotsa litšenyehelo tsa ts'ebetso.
