Mavharavha webhora zvave zvakakosha kuti zvigadzirwa zvemvura mumidziyo yose maindasitiri uye yehurumende yakakonzerwa nekugadzira kwavo kwakakwana uye zvido zvinoshanda.

Fluid temperature: High temperature fluids (above 450 ℃) should choose high-temperature resistant valves, such as chromium molybdenum steel high-temperature gate valves used in steam pipelines. Low temperature fluids (below -40 ℃) require valves with good low-temperature toughness, and low-temperature ball valves are commonly used in liquid nitrogen and liquid oxygen pipelines.

Butterfly Valve ndiyo yeValve iyo inoshandisa disc mhando yekuvhura uye kuvhara chinhu kutenderedza kumashure uye kuswededza kusvika 90 madhigirii, kana kudzora huwandu hwesvikiro. Butterfly mavhavha haangove nechimiro chepamoyo, size size, kurema kwechiedza, size yekuisa torque, nekumhanya kwakadzika, asi zvakare nekuvhara kweruzivo rwekuyerera uye kuvhara maitiro ekuyerera.

Mavharavha makobiri anoshandirwa zvakanyanya muindasitiri yemapuranga emapepa emapipi nekuda kwehuremu hwavo hwekushandisa, mashura ekuisa chisimba, uye nekureruka kwekushanda.

Mune zvidyarwa zvidyarwa, mafuta uye gasi pipi mari, masisitimu emvura, uye mamwe mashandiro eindasitiri, mavha matsime anokosha ekuyerera midziyo yekuyerera.

Semunhu akakosha pombi yekudzora, magorita anoshandiswa zvakanyanya mumaindasitiri mazhinji kunge mafuta, gasi rechisikigo, kurapwa kwemvura, maindasitiri emakemikari, nemagetsi.
