Marine Check Valve
Marine cheki mavharuvhu madhisiki edenderedzwa ane mativi ekuvhura nekuvhara anodzivirira yepakati backflow nehuremu hwawo uye yepakati kudzvanywa chiito. Kune marudzi maviri edhisiki mafambiro: kusimudza uye kuzunguza. Kusiyana nemavharuvhu epasi, simudza cheki mavharuvhu haana dzinde kutyaira disc. Kuyerera kwepakati kunoitika kubva kumagumo ekupinza (kurutivi rwezasi) kusvika kumagumo ekubuda (kumusoro divi). Kana iyo inlet pressure inodarika huwandu hwehuremu hwe disc uye kuyerera kwekudzivirira, valve inovhura. Muchiitiko apo iyo yepakati inoyerera kumashure, valve yakavharwa. Sezvakaita mavharuvhu ekusimudza, swing cheki mavharuvhu ane oblique disc inotenderera ichitenderedza shaft.
Chinangwa cheCheck Valve
Gravity cheki mavharuvhu ane flange ndiyo inonyanya kushandiswa mhando. Kana iyo svikiro yekushanda ine imwe dzvinyiriro ichipinda mugomba remukati revhavhavhavha yecheki, simba repakati rinoshanda rinobata pasi pevhavha disc kukurira simba rinokwevera zvinhu pasi, zvichiita kuti dhisiki yevharuvhu isimuke pamwe negwara rinotungamira pachivharo uye. siya vharafu. Panguva ino, chiteshi chevhavha chekuongorora chinovhurwa.
Nesimba rinokwevera zvinhu pasi, dhisiki yevharuvhu inowira kumashure kuchigaro chevharuvhu apo svikiro rekushanda rinodzokera kukamuri yekupinza yevhavhavha yekuongorora. Munguva ino, iyo inodzoka yekushanda yepakati inoshanda pane disc valve. Nekudzvanya disc zvakasimba kurwisa chigaro chevhavha, cheki chevhavha inovhara, ichidzivirira kudzoka shure.
Swing ruoko cheki mavharuvhu anowanikwawo mukuwedzera kune giravhiti cheki mavharuvhu. Inonziwo anti-wave valve. Anti-wave valve ine muviri wevharuvhu, dhisiki yevharuvhu, uye shaft inotenderera. Iyo yekushanda yepakati inowanikwa muvhavha yevhavha, iyo inobatsira. Gravity cheki mavharuvhu ane yakaderera kuyerera kuramba.
Ikoko kunewo flange uye mhando yeshinda kubatana pakati pecheki valve uye pipeline. Cast iron, cast steel, nebronze zvinhu zvesimbi zvinoshandiswa kugadzira cheki mavharuvhu (kunyanya muviri wevharuvhu).
