Tarisa Marudzi Evhavha, Zvishandiso uye Mamiriro Ekusarudza

Ngatitarisei mhando dzakasiyana-siyana dzemavharuvhu echeki uye tikurukure kuti anoshanda sei, mashandisirwo aanoitwa, uye kuti tingasarudza sei mhando chaiyo.
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 akasiyana 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, ivo vese vanovimba nekudzvanya kwakasiyana kubvumira kana kurambidza kuyerera kwemvura.Kusiyana nemamwe mavharuvhu pamusika, cheki mavharuvhu haadi mavharuvhu, inobata, actuators 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 ivhure inonzi "cracking pressure."Zvichienderana nekugadzirwa uye ukuru, kukosha kwekuputika uku kunosiyana nevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha.Ivhavhavhavhavhavhavhavhavhaivha kana paine kudzvinyirirwa kumashure kana kuti kuputika kunowedzera kupfuura iyo inopinza mukati.Kuvhara kwevharuvhu yecheki kunosiyana nemagadzirirwo, kureva bhora rekutarisa vharafu rinosunda bhora rakananga pamuromo kuti rivhare.Ichi chiito chekuvhara chinogonawo 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. achasundidzira chitubu uye disc inopesana negomba / orifice, kuisa chisimbiso chevhavha.Iyo nguva shoma yekufamba uye chitubu chekukurumidza chinobvumira kupindura nokukurumidza panguva yekuvhara.Iri rudzi rwevhavha inogona kuiswa yakatarisa kana yakadzika, maererano nehurongwa, uye naizvozvo inofanira kubviswa zvachose kuti iongororwe kana kugadziriswa.Idzi dzinotevera ndedzimwe mhando dzemavharuvhu ekutarisa:
Mamwe marudzi echeki mavharuvhu anosanganisira globe cheki mavharuvhu, butterfly/wafer cheki mavharuvhu, tsoka mavharuvhu, uye duckbill cheki mavharuvhu.
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. kushandisa kesi:
Zvimwe zvinhu zvinofanirwa kutariswa pakusarudza cheki vharafu zvinosanganisira: Kuenderana kweiyo cheki valve zvinhu 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.
