Mavharuvhu emhangura anowanikwa zvakanyanya mumafekitori uye chimwe chezvinhu zvinonyanya kukosha.Nekutenga mavharuvhu, shamwari dzakawanda dzinofarira kutenga mavharuvhu emhangura eTaizhou, saka ndeapi anowanzoshandiswa mumavharuvhu emhangura?Zvino ndichakuzivisai mhangura mune zvakadzama.Kurongwa kwemavharuvhu.

Zvinoenderana nemabasa uye mashandisiro, mavharuvhu emhangura anonyanya kukamurwa muzvikamu zvinotevera:

1.Mavharuvhu egedhi: Varuvhu yegedhi inoreva vharuvhu ine nhengo inovhara (gedhi) inofamba ichitevedza nzira yakatwasuka yenzira.Inonyanya kushandiswa kucheka svikiro mupombi, kureva, kuvhurika zvakakwana kana kuvharwa zvizere.

2. Ball valve: yakashanduka kubva pavhavha yevhavha, chikamu chayo chekuzarura nekuvhara chikamu, chinoshandisa sphere kutenderera 90 ° kumativi ose evhavha yevhavha kuti iwane chinangwa chekuzarura nekuvhara.

3. Vhuti yekuvharira: inoreva vharuvhu ine chikamu chekuvhara (disc) inofamba ichitevedza mutsetse wepakati pechigaro chevharuvhu.Zvinoenderana neiyo fomu yekufambisa yevhavha disc, shanduko yevhavha yechigaro chevhavha inoenderana neiyo valve disc stroke.

4. Tarisa mavharuvhu: vharafu inovhura uye inovhara kuvhara kwevhavha zvichienderana nekuyerera kwepakati pachayo kudzivirira kuvhara-kudzokera shure.

Panguva imwecheteyo, pachava nematambudziko akawanda kana mashoma panguva yekushandiswa.Kubuda kwemavharuvhu emhangura hakusi nyore sekukanganisa kushandiswa kwakajairwa, asiwo kubuda kweimwe midhiya ine njodzi inogadzirisa nekudzora maasidhi akasimba uye alkali inokonzeresa kuvuza kusingakoshi.Zviitiko zvekuchengetedza, ngatitarisei zvakanyanya nhasi.

Muchokwadi, isu tinoziva kuti chigadzirwa chikamu chakakosha chepombi.Usati waiswa uye kushandisa, zvinodikanwa kugadzira pombi zvinoenderana nekugadzika uye kushandisa mirairo yemhando dzakasiyana dzevhavha.Paunenge uchiisa uye welding papombi, iva nechokwadi chokuti valve yakazaruka zvakakwana.Dzimwe nguva tembiricha yepombi inoda kuiswa yakakwira zvakanyanya.Muchiitiko ichi, hazvibviri kuisa uye kushandisa vheji yeYuhuan, nokuti pombi inopisa inopisa ichapisa nzvimbo yekuvhara yevhavha.

Uye patinoshandisa chigadzirwa, tinodawo kuti iiswe munzvimbo yakakodzera, iyo inogona kuwedzera hupenyu hwechigadzirwa.
