inodzivirira svikiro riri mupombi kuyerera richidzoka.Ivhavha ine zvikamu zvekuvhura nekuvhara zvinovhurwa kana kuvharwa nekuyerera uye simba repakati kudzivirira svikiro kuyerera kumashure inonzi cheki valve.Cheki mavharuvhu ndeechikamu cheotomatiki mavharuvhu, ayo anonyanya kushandiswa mumapaipi apo iyo yepakati inoyerera munzira imwe, uye inongobvumira yepakati kuyerera munzira imwe kudzivirira tsaona.Rudzi urwu rwevharuvhu kazhinji runofanira kuisirwa yakatwasuka mupombi.Iyo swing cheki valve inotora yakavakirwa-mukati rocker swing chimiro.Zvose zvikamu zvekuzarura nekuvhara zvevhavha zvakaiswa mukati memuviri wevhavha uye usapinda mukati memuviri wevhavha.Kunze kwekuvhara gasket uye mhete yekuisa chisimbiso pane yepakati flange, iyo yese Hapana nzvimbo yekudonha, kudzivirira mukana wekudonha kwevharuvhu.Kubatana pakati peruwoko rwekuzunguza kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha habari habari magadhi anodhirowa anotora spherical yekubatanidza chimiro, kuitira kuti clack yevharuvhu ive neimwe dhigirii yerusununguko mukati meiyo 360 madhigirii, uye pane yakakodzera nzvimbo yekutevera muripo.Swing cheki mavharuvhu akashandiswa zvakanyanya munzvimbo dzakawanda dzakadai seindasitiri yemakemikari, simbi, uye mishonga.

Chimiro uye maitiro evhavhavha yecheki:

1. Kusarudzwa kwakanakisa kwecheki valve zvinhu, zvinoenderana nezvinodiwa zvepamba nekunze, uye yakakwirira yemhando yezvinhu.

2. Chisimbiso chekuvhara chevhavhavha yecheki yepamusoro uye inonzwisisika.Iyo yekuisa chisimbiso pamusoro pevhavha clack uye chigaro chevharuvhu chakagadzirwa nesimbi-based alloy kana stellite cobalt-based cemented carbide yakatarisana pamusoro, iyo ine kupfeka kuramba, kupisa kwekushisa kwepamusoro, corrosion resistance uye kukwenya kuramba.Hupenyu hwakanaka uye hurefu hwebasa.

3. Ivhavha yekuongorora inogadzirwa uye inogadzirwa maererano nehuwandu hwenyika GB/T12235.

4. Ivhavha yecheki inogona kutora mitemo yakasiyana-siyana yepiping flange uye marudzi ekuisa chisimbiso cheflange kuti asangane nezvinodiwa zveinjiniya zvakasiyana uye zvinodiwa nemushandisi.

5. Chigadzirwa chemuviri chevhavha chevhavhavha checheki chakakwana, uye gasket inogona kusarudzwa zvakakodzera maererano nemamiriro chaiwo ekushanda kana zvinodiwa nevashandisi, uye inogona kukodzera kudzvinyirirwa kwakasiyana-siyana, kutonhora uye kushandiswa kwepakati.Zvinoenderana nezvinodiwa nemushandisi, cheki mavharuvhu ane akasiyana zvimiro uye zvinongedzo zvinogona kugadzirwa uye kugadzirwa kuti zvishandiswe nemidziyo yakasiyana.

Cheki vharuvhu (Check valve) zvinoreva vharafu rinovhurika nekuvhara dhisiki zvichienderana nekuyerera kwepakati pacharo, uye rinoshandiswa kudzivirira yepakati kuti isayerera ichidzoka.Inonziwo cheki valve, imwe-nzira vharafu, reverse flow valve, uye back pressure valve.Cheki valve rudzi rweotomatiki valve, basa rayo guru nderokudzivirira kuyerera kwemashure kwepakati, kudzivirira pombi uye dhiraivha mota kubva pakudzokera kumashure, pamwe nekuburitswa kwemukati memudziyo.Cheki mavharuvhu anogona zvakare kushandiswa kugovera mapaipi ekubatsira masisitimu uko kudzvanywa kunogona kukwira pamusoro pesimba rehurongwa.Cheki mavharuvhu anogona kunyanya kukamurwa kuva swing cheki mavharuvhu uye simudza cheki mavharuvhu.Ivhavha yekuongorora inokodzera mapaipi emamiriro akasiyana-siyana ekushanda mu petroleum, chemikemikari, mishonga, fetereza, uye magetsi emagetsi emagetsi ane simba rePN1.6 ~ 16.0MPa uye kutonhora kwekushanda kwe -29 ~ + 550 °.Iyo inoshandiswa svikiro imvura, mafuta, chiutsi, Acidic medium, nezvimwe.

Cheki vharuvhu inovhurwa otomatiki uye yakavharwa nechisimba chinogadzirwa nekuyerera kwepakati pachayo mupombi, uye ndeye otomatiki valve.Ivhavhavha yekuongorora inoshandiswa mupiping system, uye basa rayo guru nderokudzivirira yepakati kubva pakuyerera shure, kudzivirira pombi uye motokari yayo yemotokari kubva pakudzokera shure, uye kuburitsa svikiro mumudziyo.Ivhavha yecheki inogonawo kushandiswa kugovera mapaipi apo kudzvinyirirwa kwegadziriro yekubatsira kunogona kukwira pamusoro pekumanikidzwa kwegadziriro huru.Basa revhavha yecheki nderokudzivirira svikiro riri mupombi kuti rirege kuyerera richidzoka.Cheki mavharuvhu ndeechikamu cheotomatiki mavharuvhu, anovhura kana kuvhara otomatiki nechisimba chepakati inoyerera.Ivhavhavha yecheki inongoshandiswa mupombi apo iyo yepakati inoyerera munzira imwe kudzivirira yepakati kuti irege kudzoka kudzivirira njodzi.Iyo inoshandiswa svikiro yevhavhavha yekutarisa imvura, mafuta, steam, acid medium, nezvimwe.
