Tarisa Mhando dzeVaruvha, Zvishandiso uye Mamiriro Ekusarudza

Ngatitarisei mhando dzakasiyana-siyana dzemavharuvhu echeki uye tikurukure kuti anoshanda sei, mashandisirwo aanoitwa, uye kuti tingasarudza sei mhando yakanaka. Zvirongwa zvakagadzirirwa kubvumira media media kuyerera munzira imwe chete kazhinji ine cheki mavharuvhu.Mienzaniso yemaitiro akadaro anosanganisira mapaipi etsvina, uko tsvina inogona kungoyerera mune imwe nzira.Check mavharuvhu anoshandiswawo uko kuyerera kwemashure kunogona kukonzera kukuvara kwemidziyo.Tisati tawana. kupinda dzakasiyana cheki vharafu mhando, mafomu, uye kusarudzwa maitiro, ngatitangei kunzwisisa sei cheki mavharuvhu kushanda. Cheki valve kana cheki valve mudziyo unorambidza kuyerera kwemvura munzira imwe chete.Cheki mavharuvhu ane zviteshi zviviri, chinopinda uye chekubuda nacho, uye akagadzirirwa kudzivirira kudzoka kwemvura mumaindasitiri akasiyana siyana.Kune marudzi akasiyana e cheki mavharuvhu, uye anosiyana mumagadzirirwo anoita kuti avhure uye avhare.Zvisinei, vose vanotsamira pakudzvinyirirwa kwakasiyana-siyana kubvumira kana kudzora kuyerera kwemvura.Kusiyana nemamwe mavharuvhu ari pamusika, mavharuvhu echeki haadi mavharuvhu, mabatiro, mavharuvhu kana kupindira kwevanhu kuti vashande zvakanaka.Izvo zvakachipa, zvinobudirira uye zviri nyore kushandisa.Kureva kuti, cheki chevhavha inongoshanda chete kana pane kudzvinyirirwa kusiyanisa pakati pekupinda nekubuda.Iyo shoma yekusiyanisa kudzvinyirira iyo system inofanira kudarika kuitira kuti valve yekuvhura inonzi "cracking pressure."Zvichienderana nekugadzirwa uye ukuru, kukosha kwekuputika uku kunosiyana nevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha.Ivhavhavhavhavhavhavhavhavhavhavhavha kana pane kudzvinyirirwa shure kana kuputika kwepamusoro kwakakwirira kudarika inlet pressure. Kuvhara kwevharuvhu yecheki kunosiyana nemagadzirirwo, kureva kuti vharafu yekuongorora bhora inosunda bhora kugonhi kuti rivhare. Ichi chiito chekuvhara chinogona zvakare kubatsirwa negiravhiti kana zvitubu. Sezvambotaurwa, kune marudzi akawanda evhavhavhavha yekuongorora, imwe neimwe yakagadzirirwa kushandiswa kwayo kwakasiyana.Zvisinei, rudzi runonzi spring-loaded in-line check valve inoshandiswa mumhando dzakasiyana-siyana dzemaindasitiri.Spring-type in-line check valves. ine zvitubu, miviri yevharuvhu, madhisiki uye madhairekitori.Kana iyo inlet pressure yakakwira zvakakwana kuti ikunde kutsemuka kwemhepo uye simba remvura, inosundidzira chivharo chevhavha, ichivhura gomba uye ichibvumira mvura kuyerera kuburikidza nevhavha. ichasundira chitubu uye dhisiki pamusoro pegomba / orifice, kuisa chisimbiso chevhavha.Nhambo pfupi yekufamba uye kukurumidza-kuita chitubu chinobvumira kukurumidza kupindura panguva yekuvhara.Rudzi urwu rwevhavha inogona kuiswa yakatarisa kana yakadzika, maererano nehurongwa, uye naizvozvo inofanira kubviswa zvachose kuti iongororwe kana kugadziriswa.Idzi dzinotevera ndedzimwe mhando dzemavharuvhu echeki: Mamwe marudzi emavhavhavha ekuongorora anosanganisira globe check valves, butterfly/wafer check valves, foot valves, uye duckbill check valves. Cheki mavharuvhu anoshandiswa munenge maindasitiri ese umo mvura inofanira kuyerera munzira imwe chete.Mavharuvhu aya anoshandiswawo mumidziyo yemumba yakadai semichina yekuwachisa uye yekugezesa dishwasher.Zvichienderana nekugadzirwa uye maitiro ekushanda, cheki mavharuvhu anogona kushandiswa chero ipi zvayo inotevera. shandisa zviitiko: Zvimwe zvinhu zvinofanirwa kutariswa pakusarudza cheki valve zvinosanganisira: Kuenderana kwezvinhu zvevhavha yekutarisa neiyo fluid medium. Chengetedza mavharuvhu ndiwo midziyo yakakurumbira muzvigadzirwa zvemabhizimisi izvo zvisingadhuri uye zvakavimbika, asiwo zviri nyore kushandisa.Paunotenga cheki valve, iva nechokwadi chokuti unonzwisisa zvaunoda zvakasiyana uye chengetedza maitiro ekusarudza valve.Uyewo, iva nechokwadi chokuti unonzwisisa kuiswa. zvinodiwa kudzivirira mafambiro ekutungamira nyaya kana kukuvadzwa kune yako system nekuda kwekumanikidza kuvaka-up. Charles Kolstad ave naTameson kubvira 2017 uye anobva kuUnited States of America.Ane dhigirii reMechanical Engineering kubva kuSt Thomas University, Minnesota, USA.Anoshanda ari kure apo achifamba muEurope, Asia neAmerica.Zvisinei, anoshanyira muzinda waTameson nguva nenguva kuti asangane nenhengo itsva dzechikwata uye kushanda kubva kuhofisi.
