Musiyano uripo pakati pekunyararidza cheki mavharuvhu uye chinyararire cheki mavharuvhu zvakanyanya zvinoenderana nedanho rekunyarara.Kunyarara cheki vharafuchete kubvisa ruzha uye kuderedza ruzha.Silent check valveinogona kudzivirira zvakananga nekunyaradza ruzha kana yashandiswa.
Silent cheki mavharuvhuanonyanya kushandiswa pamapaipi ehurongwa hwemvura uye anoiswa panobuda pombi yemvura.Inoumbwa nemuviri wevharuvhu, dhisiki yevharuvha, tsinde yevharuvhu, chitubu uye zvimwe zvikamu.Iyo yekuvharisa sitiroko ipfupi uye reverse kuyerera kumhanya idiki panguva yekuvhara.Iyo valve disc seal inotora rabha yakapfava chisimbiso, uye kudzoka kwechirimo kunoita kuti vharuvhu ivhurwe uye ivharwe pasina kukanganisa, kuderedza ruzha uye mvura sando mhedzisiro, saka inonzi silencer cheki vharafu.Iyo yevhavha yepakati inotora chimiro chekusimudza uye imhando yekusimudza cheki valve.
Kunyarara cheki mavharuvhuzvinonyanya kuiswa vertically.Kune maviri-sided guide valve cores, anogonawo kuiswa akatwasuka.Zvisinei, kune mavharuvhu makuru-diameter, kuzvidzora kwevhavha disc yakakura, iyo ichaita kuti unilateral ipfeke pane sleeve yemutungamiri, uye mumatambudziko akaoma anokanganisa kushanda kwekuvhara.Nokudaro, zvinokurudzirwa kuisa vertically kune mavharuvhu makuru-diameter.
Iyo yakanyarara cheki vharafu zvakare yakanzi axial flow cheki vharafu, chinhu kiyi mudziyo wakaiswa panobuda pombi kana compressor kudzivirira yepakati kuyerera.Nemhaka yokuti axial flow check valve ine maitiro ehutano hwakasimba hwekuyerera, kupikisa kuduku kwekuyerera, maitiro akanaka ekuyerera, kuvhara kwakavimbika uye kusina nyundo yemvura pakuzarura nekuvhara.Inoiswa pamvura inopinza yepombi yemvura uye inogona kukurumidza kuvharwa mvura isati yadzokera shure., kudzivirira nyundo yemvura, sando yemvura inonzwika uye inoparadza kuita kuti iite chinyararire.Naizvozvo, yakave yakashandiswa zvakanyanya muoiri uye gasi kureba mapaipi, nyukireya magetsi chirimwa mvura huru, compressors uye mapombi makuru mumiti mikuru ethylene, nezvimwe.
Iyo inonyanya kuumbwa nemuviri wevharuvhu, chigaro chevharuvhu, dhisiki yevharuvhu, chitubu, dhizaini tsvimbo, inotungamira sleeve, chivharo chegwara uye zvimwe zvikamu.Iro mukati memuviri wevharuvhu, chivharo chegwaro, dhisiki yevharuvhu uye dzimwe nzvimbo dzinoyerera-inoyerera dzinofanirwa kukwenenzverwa kuti zvisangane nedhizaini yechimiro che hydraulic, uye inofanira kutenderedzwa kumberi uye yakanongedza kumashure kuti iwane nzira yemvura iri nani.Iyo fluid inoshanda zvakanyanya sekuyerera kwelaminar pamusoro payo, paine kushomeka kana kusavapo.Iyo yemukati yemukati yemuviri wevhavha ndeye Venturi chimiro.Kana iyo mvura ichiyerera nemugero wevharuvhu, inoderera zvishoma nezvishoma uye inowedzera, ichideredza chizvarwa cheeddy currents.Kurasikirwa kwekumanikidzwa kudiki, kuyerera kwemaitiro kwakagadzikana, hakuna cavitation, uye yakaderera ruzha.
Inogona kuiswa yakatwasuka uye yakatwasuka.Kana dhayamita yakakura yakasimwa yakatarisa, tsvimbo yemutungamiri inofanira kutora maitiro maviri ekutungamirira kuti arege kunyanya kupfeka kune rumwe rutivi rwechigadziro chegwara uye tsvimbo yemutungamiri inokonzerwa nekurema kwevhavha disc.Izvi zvinokonzera kuti valve disc sealing effect ideredze uye ruzha ruwedzere kana uchivhara.
Musiyano pakati pe Kunyarara cheki mavharuvhu uye Silent cheki mavharuvhu:
1. Chimiro chevhavha yakasiyana.Chimiro che silencer cheki chevhavha chiri nyore, uye inoyerera chiteshi chevhavha yekutarisa ine yakajairwa chimiro.Chimiro cheaxial flow check valve chinenge chakanyanya kuoma.Iyo yemukati yemukati yemuviri wevhavha ndeye Venturi chimiro chine inoyerera inotungamira mukati.Kuyerera kwese kwepamusoro kunokwenenzverwa.Kuchinja kwakatsetseka kwechiteshi chekuyerera kunoderedza eddy currents uye zvinobudirira kuderedza kuyerera kwekudzivirira.
2. The valve core sealing structure yakasiyana.Iyo silencer cheki valve inotora rabha yakapfava-yakavharwa valve core, uye iyo yese yevhavha core yakafukidzwa nerabha, kana chigaro chevharuvhu chakavharwa nemhete yerabha.Axial kuyerera cheki mavharuvhu anogona kushandisa simbi yakaoma zvisimbiso uye yakaoma alloy yakatarisana, kana yakapfava uye yakaoma composite yekuisa chisimbiso zvimiro.Nzvimbo yekuisa chisimbiso inowedzera kusimba uye inowedzera hupenyu hwebasa.
3. Mamiriro ekushanda anoshanda akasiyana.Chinyararire cheki mavharuvhu anonyanya kushandiswa mune yakajairika tembiricha mapaipi akadai semvura masisitimu, ane zita rekumanikidza PN10--PN25 uye madhayamita DN25-DN500.Zvishandiso zvinosanganisira simbi yakakandwa, simbi yakakandwa, uye simbi isina tsvina.Axial flow check mavharuvhu anoshandiswa muhuwandu hwakawanda hwekushandisa, kubva kune liquefied gasi rechisikigo pane yakaderera tembiricha ye -161 ° C kusvika kumusoro-tembiricha mupfu.Nominal pressure PN16-PN250, American standard Class150-Class1500.Diameter DN25-DN2000.
