Chii chandinofanira kuita kana cheki valve isingagoni kumisa mvura?

Haikwanisecheki vharafukumisa mvura? Nzira idzi dzichakubatsira kuigadzirisa

Cheki mavharuvhu anofanirwa kuve "vachengeti vakavimbika" kudzivirira kuyerera kwemvura, asi kana vakatadza kumisa mvura, zvinogona kukonzera dambudziko rakawanda. Nekudaro, usazvinetse, tinogona kuongorora nekugadzirisa dambudziko kubva kune akawanda maficha.

Kuiswa kwacho kunoda kutanga kutariswa.Tarisa mavharuvhuiva nemavara akajeka ekuyerera kwemvura. Kana yaiswa munzira isiri iyo, zvakafanana nekunongedza "nzira yekudzoka" kune kuyerera kwemvura, uye mvura inoyerera ichidzoka. Panguva ino, ingo nyatso tarisisa mamaki emiseve pavharuvhu uye woidzosera nenzira kwayo. Mukuwedzera, nzvimbo yekuisa yevhavha yekuongorora inodawo kutarisirwa. Kana iyo yakaiswa pa bend yepombi kana pedyo nekubuda kwepombi yemvura, mamiriro ekuyerera kwemvura achave akaoma uye simba rinokonzera richave rakakura, izvo zvinokanganisa kushanda kwayo kwakajairika. Inofanirwa kuiswa papombi yakachinjika uye yakatsiga yekuyerera kwemvura, kure nemabhendi uye pombi dzepombi, kugadzira nzvimbo yakanaka yekushanda kwayo.

Kukuvadzwa kwechikamu ndichowo chikonzero chakajairika. Iyo valve disc uye chigaro chevharuvhu zvikamu zvakakosha zvekuzadzisa chisimbiso mucheki mavharuvhu. Kana dhisiki revharuvhu rakasakara uye risingakwanisi kunyatsoenderana nechigaro chevharuvhu, mvura inodonha nepakati. Saizvozvo, deformation yechigaro chevhavha inogonawo kukanganisa iyo yekuisa chisimbiso. Kune matambudziko akadai, kana dhigirii rekupfeka kana deformation rakareruka, maturusi ekukuya anogona kushandiswa kukuya zvakatsetseka nzvimbo yekuisa chisimbiso kuti idzorere flatness uye kutsvedzereka; Kana kukuvara kwakanyanya, dhisiki nyowani yevharuvhu kana chigaro chinoda kutsiviwa. Kukundikana kwechitubu hakugoni kuregererwa. Iyo inotarisira kudhonza panguva yakakodzera dhisiki yevhavha kudzokera kunzvimbo yakavharwa kana kuyerera kwemvura kunomira. Kana chitubu kuneta, ngura, uye kurasikirwa elasticity, vharafu disc haigoni kuvharwa nenguva. Panguva ino, chitubu chitsva chine zvirevo zvakafanana sechirimo chepakutanga chinoda kutsiviwa.

Iyo yepakati factor inogonawo kukonzera kukundikana kweiyocheki vharafu. Kana mvura iine hutsvina hwakakura hwakaita sediment, ngura, zvichingodaro, tsvina iyi inonamira pakati pevharuvhu disc nechigaro chevharuvhu, ichitadzisa vharavhavha disc kuvhara. Sefa inogona kuiswa pamberi pevhavha yekuongorora, uye firiji yefiriji inofanira kucheneswa nguva dzose kuti kuderedze kusvibiswa kubva kupinda muvharuvhu. Mukuwedzera, kutonhora uye kudzvinyirira kwemvura kunogonawo kukanganisa kushanda kwecheki mavharuvhu. Kana ikadarika chiyero chayo chakayerwa, matanho ekugadzirisa anowirirana anofanirwa kutorwa, sekuisa mavharuvhu ekuderedza kumanikidza kana midziyo yekutonhodza.
