VALVE KUSHANDISA

Kuti zvizadzise zvinodikanwa zvegadziriro yakanyatsogadzirwa yekuunganidza mvura, marudzi akasiyana-siyana evhavha anoshandiswa. Dzinodzora uko marudzi akasiyana emvura anogona uye asingagoni kuenda. Zvishandiso zvekuvakisa zvinosiyana zvichienderana nemitemo yenzvimbo, asi polyvinyl chloride (PVC), simbi isina tsvina, uye mhangura/bhuronzi ndiyo inonyanya kuwanda.

Tataura izvozvo, pane anosiya. Zvirongwa zvakatemerwa kusangana ne "Living Building Challenge" zvinoda kuomarara zvimiro zvekuvaka uye kurambidza kushandiswa kwePVC uye zvimwe zvinhu zvinoonekwa zvinokuvadza nharaunda nekuda kwemaitiro ekugadzira kana nzira dzekurasa.

Mukuwedzera kune zvigadzirwa, pane zvingasarudzwa zvekugadzira uye rudzi rwevhavha. Zvimwe zvechinyorwa chino zvinotarisa zvakajairwa mvura inonaya uye greywater yekuunganidza masisitimu madhizaini uye mashandisiro emhando dzakasiyana dzemavharuvhu mudhizaini yega yega.

Kazhinji kutaura, kuti mvura yakaunganidzwa ichashandiswa sei zvakare uye kuti macode epombi emunharaunda anoshandiswa sei achakanganisa rudzi rwevhavha inoshandiswa. Chimwe chokwadi chiri kutariswa ndechekuti huwandu hwemvura huripo hwekuunganidza hunogona kunge husina kukwana kuzadzisa 100% yekushandiswazve zvinodiwa. Muchiitiko ichi, mvura yemumba (yemvura yekunwa) inogona kuverengerwa muhurongwa hwekugadzirisa kushomeka.

Chinonyanya kunetsa masangano anoona nezvehutano hweveruzhinji nepombi kupatsanura zvitubu zvemvura zvemumba kubva pakubatana kwemvura yakaunganidzwa uye kusvibiswa kunogona kuitika kwemvura yekunwa mudzimba.

KUCHENGETA/KUCHENANA

Tangi remvura remazuva ese rinogona kushandiswa kugezesa zvimbuzi uye midziyo yekuuraya utachiona kuitira kutonhora shongwe yekuwedzera maapplication. Kune masisitimu ekudiridza, zvakajairika kupomba mvura zvakananga kubva mudura kuti ishandiswe zvakare. Muchiitiko ichi, mvura yakananga inopinda muchikamu chekupedzisira chekusefa uye tsvina isati yasiya masprinklers emvura yekudiridza.

Mavharuvhu ebhora anowanzo shandiswa pakuunganidza mvura nekuti anogona kuvhura nekuvhara nekukurumidza, ane yakazara port flow distribution uye low pressure loss. Dhizaini yakanaka inobvumira midziyo kuti ive yega kuitira kugadzirisa pasina kukanganisa iyo yese system. Semuenzaniso, tsika yakajairika ndeyekushandisabhora mavharuvhupamatangi nozzles kugadzirisa midziyo yepasi pasina kudonhedza tangi. Iyo pombi ine valve yekuzviparadzanisa, iyo inobvumira pombi kugadziriswa pasina kubvisa pombi yose. A backflow kudzivirira valve (cheki vharafu) inoshandiswawo mukuzviparadzanisa (Mufananidzo 3).

KUDZIVIRIRA KUSIRIRA/KURAPA

Kudzivirira kudzoka shure chikamu chakakosha cheimwe nzira yekuunganidza mvura. Spherical cheki mavharuvhu anowanzo shandiswa kudzivirira pombi kudzoka kana pombi yakavharwa uye system yekumanikidza inorasika. Mavharuvhu echeki anoshandiswawo kudzivirira mvura yemumba kana kuti mvura yaunganidzwa kuti isayerera ichidzoka, izvo zvinogona kukonzera kuti mvura isvibiswe kana kupinda pasina anoda.

Kana pombi yemita ichiwedzera chlorine kana kemikari yedhayi yebhuruu kumutsara wakadzvanywa, kavharuvhu kadiki kanonzi jekiseni valve inoshandiswa.

Mucheka wakakura kana kuti disc check valve inoshandiswa nefashama system pane tangi yekuchengetedza kudzivirira kudzoka kwemvura yetsvina uye kupindira kwemakonzo mumvura yekuunganidza mvura.

17 sum water fig5 Mavharuvhu eshavishavi anofambiswa nemaoko kana nemagetsi anoshandiswa sevharuvhu yekuvharira mapaipi makuru (Mufananidzo 5). Nekushandisa pasi pevhu, mavharuvhu anofambiswa negiya anoshandiswa kuvhara kuyerera kwemvura mutangi remvura, iro rinogona kubata mazana ezviuru zvemarita emvura, kuitira kuti pombi iri mutsime rakanyorova igadziriswe zvakachengeteka uye nyore. . Iyo shaft yekuwedzera inobvumira kutonga kwemavharuvhu pazasi pemateru kubva padanho remateru.

Vamwe vagadziri vanoshandisawo lug-type butterfly mavharuvhu, anogona kubvisa mapombi ezasi, saka vharafu inogona kuvharika. Aya mavharuvhu eshavishavi akasungirirwa kuti aenderere mberi nemativi ese evharuvhu. (Wafer butterfly valve haibvumiri basa iri). Cherechedza kuti muMufananidzo 5, valve uye kuwedzera zviri mutsime rakanyorova, saka valve inogona kushandiswa pasina bhokisi revhavha.

Kana zvikumbiro zvakaderera zvakadai semvura tank drainage inoda kutyaira valve, valve yemagetsi haisi sarudzo inoshanda nokuti magetsi emagetsi anowanzokundikana pamberi pemvura. Kune rumwe rutivi, mavharuvhu epneumatic anowanzo kusabatanidzwa nekuda kwekushaikwa kwemhepo yakamanikidzwa. Hydraulic (hydraulic) actuated valves kazhinji ndiyo mhinduro. Yemagetsi pilot solenoid yakachengeteka iri pedyo nepaneru yekudzora inogona kuendesa mvura yakamanikidzwa kune inowanzovharwa hydraulic actuator, iyo inogona kuvhura kana kuvhara valve kunyangwe iyo actuator yakanyura. Kune ma hydraulic actuators, hapana njodzi yekuti mvura inosangana neiyo actuator, inova ndiyo mamiriro emagetsi emagetsi.

mukupedzisa
Pa-saiti mashandisirwo emvura masisitimu haana kusiyana nemamwe masisitimu anofanirwa kudzora kuyerera. Mazhinji emisimboti anoshanda kune mavharuvhu uye mamwe masisitimu ekurapa emvura anongogamuchirwa nenzira dzakasiyana kuti asangane nezvinodiwa zvakasiyana zveiyi inobuda indasitiri yemvura. Zvakangodaro, sezvo kudanwa kwezvivakwa zvakatsiga kunowedzera zuva rega rega, iyi indasitiri ingangove yakakosha kuindasitiri yevharuvhu.
