Kukunda kupikisa kwechitubu kunoita kuti valve ivhure kana kuvhara.Kana iyo yepakati dzvinyiriro pamagumo ekupinza yakaderera pane iyo inopinza, iyo vertical cheki vharafu: nekuda kwekumanikidzwa kwepakati painopinza yepipeline.Chitubu chinosundira core yevharuvhu kuchigaro chevharuvhu kuti ivhare vharafu, ichidzivirira yepakati kuti irege kuyerera kumashure, saka ine basa risingadzoke.Vertical cheki mavharuvhu anoshandiswa zvakanyanya mumakemikari, liquefied petroleum gasi, fluid uye mamwe maindasitiri.Zvinoenderana nechimiro chevhavhavha yekutarisa, inogona kukamurwa kuva marudzi matatu: simudza cheki vharafu, simudza cheki vharafu uye butterfly cheki vharafu.
Ivhavhavha inoshandiswa kudzivirira yepakati kubva pakuyerera kumashure inonziwo cheki valve, imwe-nzira valve, reverse flow valve, uye back pressure valve.Ivhavha yekuongorora imhando yevhavha yega yega, basa rayo guru nderokudzivirira kuyerera kwemashure kwepakati, kudzivirira pombi uye motokari yemotokari kubva pakudzokera shure, uye kubudiswa kwemukati wemudziyo.Cheki mavharuvhu anogona zvakare kushandiswa kupa mapaipi uko kudzvanywa kunogona kukwira kune yekubatsira sisitimu inodarika kudzvanywa kwehurongwa.Cheki mavharuvhu anogona kukamurwa kuita swing cheki mavharuvhu (anotenderera zvinoenderana nepakati pesimba regiravhiti) uye simudza cheki mavharuvhu (achifamba achitevedza axis).Basa remhando iyi yevhavha ndeyekungobvumira svikiro kuti riyerere mune imwe nzira uye kudzivirira kuyerera kwegwaro.Kazhinji rudzi urwu rwevhavha rinongoshanda pasi pechiito chemvura inoyerera inoyerera mune imwe nzira, iyo valve flap inovhura;apo mvura inoyerera ichienda kune imwe nzira, iyo mvura inodzvinyirira uye kuzvidzora kwevhavha yevhavha inobata pachigaro chevhavha, nokudaro ichicheka kuyerera.Pakati pazvo, iyo yemukati shinda yekutarisa vharafu uye vertical cheki vharafu zvinoreva kuvhura otomatiki uye kuvhara kwevhavha clack zvichienderana nekuyerera kwepakati pachayo.Akabatanidzwa cheki mavharuvhu ndeerudzi urwu rwevharuvhu, kusanganisira swing cheki mavharuvhu uye anosimudza cheki mavharuvhu.Iyo swing check valve ine intermediary chain mechanism uye dhisiki yevharuvhu segonhi rinogara zvakasununguka pamusoro pechigaro chevhavha yakarerekera.Kuti ive nechokwadi chekuti chivharo chevhavha chinogona kusvika panzvimbo yakakodzera yechigaro chevhavha pese nguva dzose, valve clack inogadzirwa mumaketani kuitira kuti valve clack ine nzvimbo yakakwana yekutendeuka uye inoita kuti valve inyatso uye inyatsobatana. chigaro chevharuvhu.Iyo valve clack inogona kugadzirwa nesimbi, dehwe, rabha, kana synthetic yekuvhara inogona kuiswa pasimbi, zvichienderana nekuita zvinodiwa.Kana iyo swing cheki valve yakavhurwa zvizere, iyo fluid pressure inenge isina kuvharidzirwa, saka kudonha kwemhepo kuburikidza nevhavha kunenge kudiki.Ivhavha disc yevhavha yekusimudza yevhavha yakagara pamusoro pekuvhara pamusoro pechigaro chevhavha pamutumbi wevhavha.Kunze kwekuti dhisiki inogona kusimudzwa uye kuderedzwa zvakasununguka, iyo yose yevhavha iyi yakafanana nevhavha yekuvhara.Mvura inodzvinyirira inosimudza dhidhi kubva pachisimbiso chechigaro chevhavha, uye kudzoka kwepakati kunokonzera kuti disc idzokere pachigaro uye icheke kuyerera.Zvinoenderana nemamiriro ekushandiswa, dhisiki yevharuvhu inogona kunge iri-yesimbi dhizaini, kana inogona kunge iri muchimiro chepedhi rerubha kana mhete yerubha yakaiswa pane disc frame.Kufanana nevhavha yekumisa, kuyerera kwemvura kuburikidza nevhavha yekuongorora yekusimudzira zvakare yakamanikana, saka kudonha kwemhepo kuburikidza nevhavhavhavha yekusimudzira yakakura kudarika iyo yevhavha yekuongorora ye swing, uye kuyerera kwevhavha yekusimudza kunowedzera zvishoma.

Nortech ndeimwe yeanotungamira maindasitiri ekugadzira mavharuvhu muChina ane quality certification ISO9001.
