Ivhavha yakachekwa inonyanya kushandiswa kucheka kana kubatanidza kuyerera kwepakati. Kusanganisiragedhi mavharuvhu, mavharuvhu epasi, diaphragm mavharuvhu,bhora mavharuvhu, mavharuvhu,butterfly mavharuvhu, mavharuvhu, mavharuvhu epuragi yebhora, mavharuvhu emhando yetsono, nezvimwe

Kugadzirisa mavharuvhu anonyanya kushandiswa kugadzirisa kuyerera uye kumanikidza kwepakati. Kusanganisira regulating vharafu, throttle vharafu, pressure kuderedza vharafu, etc.

Cheki mavharuvhu anoshandiswa kudzivirira yepakati kubva kuyerera kumashure. Inosanganisira cheki mavharuvhu ezvimiro zvakasiyana.

Shunt mavharuvhu anoshandiswa kupatsanura, kugovera kana kusanganisa midhiya. Kusanganisira zvimiro zvakasiyana-siyana zvekugovera mavharuvhu uye misungo, nezvimwe.

Mavharuvhu ekuchengetedza anoshandiswa kuchengetedza kuchengetedza kana iyo yepakati yanyanya kudzvanywa. Kusanganisira marudzi akasiyana-siyana ekuchengetedza mavharuvhu.

Inokamurwa ne main parameters

(1) Kurongwa nedzvinyiriro

Ivharuvhu ine kushanda kwayo kwakadzikira pane yakajairwa atmospheric pressure.

Low pressure valve ivharuvhu ine zita rekumanikidza PN iri pasi pe1.6MPa.

Iyo yekumanikidza yezita repakati pressure valve ndeye PN2.5 ~ 6.4MPa.

Ivhavha yepamusoro ine simba rezita rePN10.0 ~ 80.0MPa.

Ultra-yakakwirira pressure valve ivharuvhu ine zita rekumanikidza PN yakakura kupfuura 100MPa.

(2) Yakarongedzerwa nepakati tembiricha

Iyo tembiricha yevharuvhu t yakakura kupfuura 450C.

Iyo yepakati tembiricha vharuvhu 120C ishoma pane vharafu ine t isingasviki 450C.

Normal tembiricha vharafu -40C ishoma pane t isingasviki 120C.

Low tembiricha vharafu -100C ishoma pane t iri pasi pe -40C.

Iyo yekupedzisira-yakaderera tembiricha vharuvhu t isingasviki -100C.

(3) Kurongwa nevharuvhu muviri zvinhu

Non-metallic zvinhu mavharuvhu: akadai zvedongo mavharuvhu, girazi simbi mavharuvhu, epurasitiki mavharuvhu.

Metal zvinhu mavharuvhu: akadai semhangura alloy mavharuvhu, aruminiyamu alloy mavharuvhu, lead alloy mavharuvhu, titanium alloy mavharuvhu, Monel alloy mavharuvhu

Kanda simbi mavharuvhu, kabhoni simbi mavharuvhu, akakanda simbi mavharuvhu, yakaderera alloy simbi mavharuvhu, yakakwirira alloy simbi mavharuvhu.

Metal vharafu muviri lining mavharuvhu: akadai lead-lined mavharuvhu, epurasitiki-lined mavharuvhu, uye enamel-lined mavharuvhu.
