6. Iyo yepakati flange (kubatanidzwa pakati pevhavha yemuviri nemuviri wekuruboshwe) haina hurongwa hwekudonha.Kubatana pakati pemuviri wevhavha nemuviri wekuruboshwe kunovharwa nemagaskets.Kuti udzivise kuvuza nekuda kwemoto, tembiricha yakakwira kana kuzununguka, yakanyatsogadzirirwa kuMuviri wevharuvhu unosangana nesimbi-simbi kuruboshwe muviri kuti ugadzire yakagadziriswa orifice flange kuve nechokwadi kuti hapana kuvuza.

 

7. Chimiro chekudzivirira moto Kana njodzi yemoto ikaitika, zvinhu zvisiri zvesimbi zvakadai sezvigaro zvevharuvhu uye mafirita zvichapiswa, uye huwandu hukuru hwema media akaburitswa hunogona kuwedzera kusimudzira moto.Iyo yekudzivirira moto chimiro chevhavha inogona kudzivirira huwandu hukuru hwekudonha kwepakati.Mushure memoto, zvikamu zvinobuda (bhora nevharuvhu muviri, tsinde yevharuvhu uye muviri wevharuvhu, yepakati flange) yakagadzirirwa kuve yakabatana nesimbi kuti isangane nezvinodiwa zvekudzivirira moto.Sezvinoratidzwa mumufananidzo, kana chigaro chevharuvhu chapiswa, bhora rinosangana zvakananga nesimbi pamusoro pemuviri wevharuvhu pasi pekumanikidzwa, nekudaro kudzivirira huwandu hukuru hwepakati kubva pakudonha kubva pachigaro chakatsva chevharuvhu.

 

2. Pressure-Temperature Rating

 

Iyo yekumanikidza uye tembiricha chiyero chevhavhavha yebhora haina hukama chete neganda zvinhu, asi zvakare zvine hukama nechinhu chekuisa chisimbiso senge chigaro chevhavha, kurongedza uye gasket.Chisimbiso chinogona kuva polymer zvinhu, asbestos kana rabha.Kusarudzwa kwezvinhu zvechisimbiso zvinoenderana nekuumbwa kwepakati, tembiricha yekushanda, kushanda nesimba uye kuyerera kwevhavha.

 

Kune akasiyana-siyana asingatarisirwi mamiriro ekushanda, zvakanyanya kuoma kunyatsoona kudzvanywa-tembiricha rating yevhavha.Kubva pane yedu yenguva refu yekugadzira mavharuvhu ruzivo uye yakakosha mhinduro kubva kune vatengi, isu tiri pano kuti tikupe iwe kudzvinyirira-tembiricha ratings yevhavha pasi pemamiriro ekushanda akagadzikana.

 

 

Nortech ndeimwe yeanotungamira maindasitiri ekugadzira mavharuvhu muChina ane quality certification ISO9001.
