Nzira yekuita sei chisimbiso chekushanda kwesimbi isina tsvina yebhora valve

Kuti uve nechokwadi chekuisa chisimbiso chevhavha yesimbi isina tsvina kana iyo yepakati yekushanda kudzvanywa yakadzikira, imwe pre-tightening pressure inofanirwa kuumbwa pakati pebhora nechigaro chekuisa chisimbiso.Muchigaro chekuisa chisimbiso chakaomarara, kuvimbika uye hupenyu hwesevhisi yesimbi isina simbi yebhora valve inosungirirwa mukusarudzwa kwakaringana kweiyo pre-kusimbisa huwandu hwechigaro chekuisa chisimbiso.

Kuvimbika uye hupenyu hwebasa resimbi isina tsvina yebhora vharafu;sunga pre-kusimbisa huwandu hwesarudzo chaiyo yechigaro chekuisa chisimbiso.Kushaikwa kwekutanga kusungirirwa hakugone kuvimbisa kudzika-kumanikidza kwevhavha yebhora: yakakura kwazvo pre-tightening ichaita kuti torque inopesana pakati pebhora uye chigaro chekuisa chisimbiso chiwedzere, chinokanganisa basa rekuita kwesimbi isina simbi yebhora;uye inogona kukonzera deformation yepurasitiki yechigaro chekuisa chisimbiso, zvichikonzera kukundikana kwekuvhara.Nezve chigaro chekuisa chisimbiso chePTFE, preload chaiyo preload inofanirwa kunge iri 0.1 PN uye isiri pasi pe1.02 MPa.

Kugadziriswa kweiyo pre-kusimbisa huwandu hwechigaro chakasimba chekuisa chisimbiso chinopedzwa nekushandura ukobvu hwechisimbiso chekugadzirisa gasket.Iko kukanganisa kwekugadzirisa kwechisimbiso kugadzirisa gasket kuchakanganisa mhedzisiro yekugadziriswa: zvine musoro midziyo uye kugadzirisa ndiyo kiyi yekuwana yakanakisa yekuisa chisimbiso kuita.Mukushanda, mushure mekunge chigaro chechisimbiso chapfekwa, kugona kugadzirisa kwe preload chaiyo kudzvanywa kwakashata, saka hupenyu hwesevhisi hwechisimbiso chakaomarara chigaro bhora vharafu ipfupi.

Imwe yenzira dzekugadzirisa dambudziko ndeyekusarudza chigaro chekuisa chisimbiso nezvinhu elastic.Panguva ino, kutora uye kugadziriswa kweiyo pre-yakasimba chiyero haichatsamira pane chisimbiso chekugadzirisa gasket asi inopedzwa neiyo elastic element.Pamusoro pekuwana iyo inodiwa pre-kusimbisa huwandu, chigaro chekuisa chisimbiso chine elastic zvinhu zvinogona zvakare kubhadhara pre-kuomesa chaiyo kudzvanywa mukati meiyo elastic deformation renji ye elastic element.Nokudaro, hupenyu hwebasa revhavha yebhora hurefu.

Kiyi yekuiswa chisimbiso chesimbi isina tsvina mavharuvhu ari muchimiro chechigaro chekuisa chisimbiso uye kusarudzwa kwechigaro chekuisa chisimbiso.Zvinoenderana neyakasiyana dhizaini uye zvinodiwa zvekushandisa, zvine musoro sarudza nzira yekuumbwa kwechigaro chekuisa chisimbiso kuti uve nechokwadi chehunyanzvi hwekugadzirisa tekinoroji yechigaro chekuisa chisimbiso: sarudza chinhu chekuisa chisimbiso chine basa rakanakisa uye zvechinyakare zvinodiwa zvekushandisa kusangana nezvinodiwa zvekuisa chisimbiso chevhavha yebhora uye mberi. kuvimbika uye kushandiswa kwekushanda kwevhavha yebhora Upenyu hunokosha hunokosha mukuronga kwekugadzirisa bhora.
