Kuronga uye kuiswa kwekutungamira kwecheki mavharuvhu
Kuongorora kwevhavhavhavha
Cheki mavharuvhu chinhu chakakosha chekudzora mvura, chinoshandiswa zvakanyanya mumapurojekiti ekuchengetedza mvura, petrochemicals, kuchengetedza kwezvakatipoteredza uye mamwe minda.Basa rayo guru nderekudzivirira kudzokororwa kwezve midhiya uye kuve nechokwadi chekuyerera kwenzira imwe chete ye media mupombi system.Kurongeka uye kuiswa kwekutungamira kwecheki mavharuvhu kunokanganisa zvakananga kuita kwavo uye hupenyu hwebasa.Ichi chinyorwa chichasuma mhando dzakasiyana dzecheki mavharuvhu uye zvinotariswa kune yavo yekumisikidza mafaera zvakadzama.
Mhando huru dzecheki mavharuvhu
Zvinoenderana nechimiro uye musimboti wekushanda, mavharuvhu ekutarisa anonyanya kukamurwa kuva anotevera marudzi:
1. Double plate check valve
2. Simudza cheki valve
3. Bhora cheki vharafu
4. Swing check valve
Kuisa nzira yemhando yevhavha yekutarisa
1. Horizontal installation: inoreva nzira yekuisa cheki yevhavha pane yakatwasuka pombi, iyo inowanzoshandiswa mune yakaderera-kumanikidza pombi masisitimu, uye dhayamita yevhavha flap yakakura kupfuura dhayamita yepombi.
2. Vertical installation: inoreva nzira yekuisa cheki chevhavha papombi yakadzika, iyo inowanzoshandiswa mu-high-pressure pipeline systems, uye dhayamita yevhavha inoputika iduku kudarika dhayamita yepombi.
1. Double-disc check valve
Dual disc cheki valve: kazhinji inosanganisira maviri semicircular discs anofamba achitenderedza stem perpendicular kusvika pakati pemvura inoyerera.Kaviri-dhisiki cheki mavharuvhu ari tsindirana mavharuvhu ane diki kureba.Iwo akaiswa pakati pemaflange maviri.Kazhinji ivo vanosungirirwa kana kuti flanged.Iwo anowanzo shandiswa mumapombi ane dhayamita ye ≤1200mm.
Kuisa nzira yeDouble-disc check valve
Kaviri-dhisiki cheki mavharuvhu anogona kuiswa horizontally kana vertically mupombi.Kuiswa kwakatwasuka kunogona kuita kuvhurwa nekuvhara kwevhavha yekutarisa kukanganiswa negiravhiti, zvichiita kuti kumhanya kwayo kwekuvhura kugadzikane uye nekunyatso kudzikisa kurasikirwa kwepombi.Kuiswa kwakasimba kunogona kuita kuti vharuvhu ibatikane negiravhiti kana yakavharwa, zvichiita kuti chisimbiso chayo chiwedzere.Mukuwedzera, kuiswa kwakadzika kunogona kudzivirira cheki chevhavha disc kubva pakudengenyeka nokukurumidza panguva yekukurumidza kuchinja kwemvura, kuderedza kudengenyeka kwedhidhi uye chigaro chevhavha, uye kuwedzera hupenyu hwebasa revhavha.
2. Swing check valve
Swing cheki mavharuvhuine valve disc.Kana iyo yepakati ichiyerera kumberi, dhisiki yevharuvhu inosundirwa yakavhurika;kana iyo yepakati ichiyerera ichidzokera kumashure, dhisiki revharuvhu rinodzoserwa kuchigaro chevharuvhu kudzivirira kuyerera.Rudzi urwu rwevharuvhu runowanzoshandiswa mumapaipi makuru-diameter nekuda kwechimiro chayo chiri nyore uye kushomeka kushoma.
Kuisa nzira yeSwing cheki valve
Swing cheki mavharuvhu anogona kuisirwa horizontally kana vertically, asi inowanzokurudzirwa kuti iiswe mumapaipi akachinjika.Zvinofanira kuonekwa kuti, zvichienderana nemamiriro ezvinhu chaiwo, swing check valve inogonawo kuiswa obliquely, chero bedzi iyo angle yekuisa isingapfuuri madhigirii 45 uye nzvimbo yekuisa yakakodzera, haizokanganisa maitiro ekuzarura nekuvhara. yevhavha.
3. Horizontal lift cheki valve
Ivharuvhu disc yehorizontal lift cheki vharafu inofamba ichikwira nekudzika ichitevedza gwara renjanji mumuviri wevharuvhu.Kana iyo yepakati ichiyerera ichienda mberi, iyo valve disc inosimudzwa;apo iyo yepakati inoyerera ichidzokera kumashure, dhisiki yevharuvhu inowira kumashure kuchigaro chevharuvhu kudzivirira kuyerera.
Kuisa nzira yeHorizontal lift cheki valve
The horizontal lift cheki vharuvhu inofanira kuiswa pahorizontal pombi.Nekuti kana yaiswa vertically, vheji yayo yepakati iri munzvimbo yakatwasuka, kuita kwayo kwepakati nechigaro chevharuvhu kunodzikira pasi pehuremu hwayo, zvichikanganisa kushanda kwekuvhara kwevhavha core.
4. Vertical lift check valve
For verticalsimudza cheki mavharuvhu, mafambiro evhavha core inofanana negwara repombi.Uye pakati pevhavha core inopindirana nepakati penzira yekuyerera.
Kuisa nzira yeVertical lift cheki valve
Vertical check valves inofanira kuiswa vertically mumapombi apo svikiro inoyerera ichikwira, nokuti simba rinokwevera pasi rinobatsira dhisiki yevharuvha kuvhara nekukurumidza kana kuyerera kwamira.
5. Bhora cheki vharafu
Ball check valve inoshandisa bhora rinokwira nekudzika mumuviri wevharuvhu.Kana iyo yepakati ichiyerera kumberi, bhora rinosundirwa kure nechigaro chevharuvhu, gwara rinovhura, uye yepakati inopfuura;apo iyo yepakati inoyerera ichienda kumashure, bhora rinodzokera kuchigaro chevharuvhu kudzivirira kuyerera.
Kuisa nzira yeBhora cheki valve
Bhora cheki mavharuvhu anogona kuisirwa pahorizontal pombi, asi akakodzera kugadzika kuisirwa, kunyanya kana yepakati ichiyerera ichikwira.Kurema kwakafa kwebhora kunobatsira kuvhara kwevhavha kana kuyerera kunomira.
Zvinhu zvinokanganisa vertical installation ye check valve
Kana uchiisa cheki vharafu, zvinhu zvakati wandei zvinofanirwa kutariswa kuti ive nechokwadi chekushanda kwayo kwakanaka:
1. Kuyerera kwakananga
Mukumisikidzwa kwakamira, mafambiro ekuyerera kwepakati akakosha.Kana ichiyerera ichienda kumusoro, dhisiki yevhavha inogona kuvhurwa nekumanikidzwa kwepakati, uye kuvhara isimba rinobatsira kuti valve disc idzokere panzvimbo yayo, asi kana ichiyerera ichidzika, mamwe matanho anogona kudiwa kuti ave nechokwadi chokuti valve inovhara zvakavimbika.
2. Gravity effect
Gravity inokanganisa kuvhura nekuvhara kwevhavha.Mavharuvhu anovimba negiravhiti kuti avhare, senge-double-plate uye kusimudza cheki mavharuvhu, anoshanda zvirinani kana achiyerera achikwira kumusoro.
3. Media maitiro
Hunhu hwenhau, senge viscosity, density, uye particle content, zvinokanganisa kushanda kwevhavha.Viscous kana particle-ine midhiya inogona kuda dhizaini yakasimba uye inogarogadzirisa kuitira kuti ive nechokwadi chekushanda kwevhavha.
4. Kuiswa nharaunda
Nzvimbo yekuisa, kusanganisira tembiricha, kudzvanywa, uye kuvapo kwezvinhu zvinoparadza, zvinokanganisa kushanda uye hupenyu hwevhavha.Kusarudza zvinhu uye zvigadziro zvakakodzera kune imwe nzvimbo inogona kuwedzera hupenyu hwebasa revhavha.
Zvakanakira vertical installation cheki valve
1. Kushandiswa kwesimba rinokwevera zvinhu pasi
Panyaya yekukwira kumusoro kwenhepfenyuro, giravhiti inobatsira valve kuvhara, inovandudza kushanda kwekuvhara, uye haidi rubatsiro rwekunze.
2. Deredza kupfeka
Kushandisa simba remagetsi uye ndiro yevhavha yekuvhara cheki valve inogona kuderedza kudengenyeka, kuderedza kupera, kuwedzera hupenyu hwebasa revhavha, uye kuderedza kuwanda kwekugadzirisa.
Zvakashata zvekuisa verticalcheki valve
1. Kuramba kuyerera
Kuiswa kwakatwasuka kunogona kuwedzera kuyerera kwekudzivirira, kunyanya kune vertical lift cheki mavharuvhu, ayo anoda kuramba kwete chete huremu hweplate yevharuvhu, asiwo kumanikidzwa kunopiwa nechitubu pamusoro peplate yevharuvhu.Izvi zvichaita kuti kuderedzwa kuyerera uye kuwedzera kushandiswa kwesimba.
2. Sando yemvura chiitiko
Kana iyo yepakati ichiyerera ichikwira kumusoro, simba revhavha yekutarisa uye simba repakati rinowedzera kudzvanywa mupombi, zvichiita kuti zvive nyore kukonzera sando yemvura chiitiko.
