IBonnet yeBolt yentsimbi eyenziwe ngeBolt
✧ Inkcazo
Ivalve yeglowubhu yentsimbi eyenziweyo sisivalo esisebenza kakhulu, esisetyenziswa kakhulu kushishino lwemichiza, ipetroleum, igesi yendalo, isinyithi, amandla ombane kunye namanye amashishini. Ivalve yeglowubhu yentsimbi ebunjiweyo ithatha isakhiwo esidityaniswe ngokupheleleyo, kwaye umzimba wevalve kunye nesango zenziwe ngamalungu entsimbi. Ivalve inokusebenza kakuhle kokutywinwa, ukuxhathisa okuqinileyo kwe-corrosion kunye nobomi benkonzo ende. Isakhiwo sayo silula, sincinci ngobukhulu, kulula ukuyifaka kunye nokugcina. Ukutshintsha kwesango kuyaguquguquka kwaye kunokunqumla ngokupheleleyo ukuhamba okuphakathi ngaphandle kokuvuza. Ivalve yeglobhu yentsimbi eyenziweyo inoluhlu olubanzi lobushushu kunye noxinzelelo oluphezulu lokusebenza, kwaye ingasetyenziselwa ukulawula ukuhamba okuphakathi phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu kunye nobushushu obuphantsi kunye neemeko zoxinzelelo oluphezulu.
✧ Iimpawu zeBonnet yeBolted Steel Globe yeBolt
1.Kulula ukwenza nokugcina ngenxa yesakhiwo sayo esilula kune-valve yeglobhu.
2.Umsebenzi wokutywina ulungile kwaye umphezulu wokutywina awuxhathisi ukunxiba kunye nemikrwelo. Xa ivalve ivuliwe kwaye ivaliwe, akukho silawuli sihlobene phakathi kwendawo yokutywina yomzimba wevalve kunye nediski yevalve. Ngenxa yoko, kukho ukunxiba okuncinci kunye nokukrazula, ukusebenza kokutywinwa okuqinileyo, kunye nobomi benkonzo ende.
3.Ngenxa yokuba i-disc stroke ye-valve yokumisa ithobekile xa ivula kwaye ivala, ukuphakama kwayo kungaphantsi kwe-valve yeglobhu, kodwa ubude bayo besakhiwo bude.
4.Inkqubo yokuvula kunye nokuvala idinga umsebenzi omningi, i-torque enkulu, kunye nexesha elide lokuvula kunye nokuvala.
I-5.Ukuxhathisa ulwelo kuphezulu ngenxa yejelo eliphakathi eligobileyo lomzimba wevalve, elikwanegalelo ekusetyenzisweni kwamandla aphezulu.
6.Ulwalathiso oluphakathi lokuhamba Ngokuqhelekileyo, ukuhamba phambili kwenzeka xa i-nominal pressure (PN) ingaphantsi kwe-16 MPa, kunye ne-medium egeleza phezulu ukusuka ezantsi kwe-valve disc. Ukuhamba kwe-counter kwenzeka xa uxinzelelo lwegama (PN) ludlula i-20 MPa, kunye ne-medium ehlayo ehla ukusuka phezulu kwidiski yevalve. ukuphucula ukusebenza kwetywina. Imithombo yeendaba yeglowubhu inokuqukuqela kwicala elinye kuphela ngelixa isetyenziswa, kwaye ayinakulungiswa.
7.Xa i-disc ivuliwe ngokupheleleyo, ihlala ikhukulisa.
✧ Izinto eziluncedo ze-API 602 ivelufa yeglowubhu yentsimbi eyenziweyo
Ngexesha lokuvula kunye nenkqubo yokuvala ivalve yeglobhu yentsimbi ekhandiweyo, ngenxa yokuba ingxabano phakathi kwediski kunye nomgangatho wokutywina womzimba wevalvu incinci kunaleyo yevalve yeglowubhu, ayinxibi.
Ukuvula okanye ukuvala i-stroke ye-valve stem ifutshane, kwaye inomsebenzi othembekileyo wokusikwa, kwaye ngenxa yokuba utshintsho lwe-valve seat port lulingana ne-stroke ye-valve disc, ilungele kakhulu ukulungiswa. yesantya sokuhamba. Ke ngoko, olu hlobo lwevalve lufanelekile kakhulu ukunqunyulwa okanye ukulawulwa kunye ne-throttling.
