The national standard flangebhora vharafuinogona kutenderera 90 madhigirii uye kuvhara zvakasimba nediki torque. Makomba emukati wevhavha akaenzana zvakakwana, izvo zvinopa kupikisa kuduku uye nzira yakananga yekuyerera kwepakati. Iyo yenyika standard flanged ball valve pachayo ine compact chimiro uye iri nyore kushanda nekuchengetedza. Flanged bhora mavharuvhu akakodzera kune ese anoshanda media semvura, zvinonyungudutsa, asidhi uye gasi rechisikigo, pamwe nenhau dzine hutsinye hwekushanda, senge oxygen, hydrogen peroxide, methane, uye ethylene. Muviri wevhavha unogona kubatanidzwa kana kusanganiswa.

The national standard flangebhora vharafuiri compact muchimiro, iri nyore kushandisa nekuchengetedza, inokodzera ruzhinji rwekushanda media senge mvura, solvent, asidhi uye gasi rechisikigo, uye ine hutsinye hwekushanda mamiriro (senge hydrogen peroxide), uye inokodzerawo media. Miviri yevharuvhu yebhora senge methane uye ethylene inogona kubatanidzwa kana kusanganiswa. Mavharuvhu akadaro anofanirwa kuisirwa horizontally mupombi.

Zvakanakira nyika mureza flanged bhora vharafu

1. Kupokana kwemvura kudiki, uye iyo yakazara-gomba bhora vharafu haina kana kuyerera kwekuyerera.

2. Chimiro chakareruka, hukuru hudiki uye uremu huremu.

3. Pedyo uye yakavimbika. Pane nzvimbo mbiri dzekuisa chisimbiso. The currentbhora vharafuyekuisa chisimbiso pamusoro pezvinhu zvinoshandiswa zvakanyanya mumapurasitiki akasiyana, uye ine yakanakisa yekuisa chisimbiso kuita, iyo inogona kuwana chisimbiso chakakwana. Inoshandiswawo zvakanyanya muvacuum systems.

4. Kushanda kwakasununguka, kuzarura nokukurumidza nekuvhara, kunongoda kutenderera 90 ° kubva kuzarura zvakakwana kusvika kuvharwa zvakakwana, izvo zviri nyore kudzora kure.

5. Kugadzirisa kwakaringana, chimiro chakareruka chevhavha yebhora, uye kazhinji inofambiswa chisimbiso mhete, iyo iri nyore kuparadzanisa uye kutsiva.

6. Kana yakazarurwa zvakakwana kana yakavharwa zvakakwana, nzvimbo yekuvhara bhora uye chigaro chevhavha inoparadzaniswa kubva pakati. Kunyangwe iyo yepakati ikapfuura, iyo valve yekuisa chisimbiso pamusoro haizoparare.

7. Iyo dhayamita inotangira kubva pamamirimita akati wandei kusvika kumamita akati wandei, uye ine huwandu hwakasiyana hwemashandisirwo, uye inogona kushandiswa pasi pekutsvaira kwepamusoro kusvika pakumanikidzwa kukuru.

8. Nekuti vharafu yebhora ine hunhu hwekupukuta painovhura nekuvhara, inogona kushandiswa kune midhiya ine yakaturikwa yakasimba particles.
