Kushandiswa kwemaitiro akanyatsosarudzwa, akaiswa uye akachengetwa ekudzivirira kwemashure anogona kudzivirira njodzi yezviitiko zvinokonzerwa ne-anti-siphon uye kudzvinyirira shure.
Kudzokera shure kunoramba kuchikonzera njodzi huru kumvura yedu yakachena. Nekuda kwemuchinjiko wemuchinjiko pakati pemvura yekunwa uye inofungidzirwa sosi ine yakashandiswa mvura, zvinwiwa zvemumaindasitiri, gasi, kana chero chimwe chinhu chinosvibisa, zviitiko zvekudzokera kumashure zvinonetsa kuona kunze kwekunge paine zvisizvo uye zviratidzo zvakakomba. Kushandiswa kwemaitiro akanyatsosarudzwa, akaiswa uye akachengetwa ekudzivirira kwemashure anogona kudzivirira njodzi yezviitiko zvinokonzerwa ne-anti-siphon uye kudzvinyirira shure.
Kutsanangura iyo chaiyo reflow mhinduro zvinoenderana nekushandisa. Izvo zvakakosha kuti uzive izvo zvinogona kukanganisa mune iripo pombi system dhizaini. Izvi zvinotevera 10 zvinotariswa pakutsanangura.
Panyaya yekuderedza kudzvinyirira kwehurongwa kurasikirwa, kuyerera kwekuita kwakakosha nekuti kunowanikwa kunowanikwa kwehurongwa hwese kunoda kuverengerwa panguva yekugadzira. Kana kurasikirwa kwekumanikidzwa kwakanyanyisa kuti sisitimu ipe simba rakakwana kune zvikamu zvaro, zvinogona kureva kuti pombi inosimudzira inofanirwa kuwedzerwa kana kuti pombi yakakura yedhayamita inofanira kushandiswa, izvo zvese zvichawedzera mari yakawanda. Kunyangwe kurasikirwa kwekumanikidzwa inzvimbo yekunetsekana mune ese masisitimu, inonyanya kukosha mumasisitimu ekudzivirira moto.
Vese vanogadzira reflow vanoburitsa kumanikidza / kuyerera macurves emidziyo yavo. Kana uchienzanisa mafambiro ekuyerera, ita shuwa kuti ese anoratidza mamiriro akafanana-nokuti kuwedzera kuyerera kwe curve uye kuderera kwekuyerera curve kunowanzo siyana zvakanyanya.
Iyo yakazara theoretical kudiwa kweiyo mvura yekugovera system inoverengerwa nekuwedzera iyo inozivikanwa yakanyanya kudiwa yezvese zvigadziriso muhurongwa. Kuyerera kwemaitiro echigadzirwa chekudzoka kunogona kukanganisa zvakananga kuyerera kwese kwese kwemvura yekunwa yechivakwa kana moto sprinkler system. Paunenge uchigadzira, ndapota teerera kune zvinodiwa zvekuyerera kwekuvaka.
Pachiyero chepamusoro chekushandiswa kwakajairika, haudi kudarika chiyero chekuyerera, pamusoro pacho iwe uchasangana nekuwedzera kukuru kwekupfeka uye kubvarura. Kune masisitimu ekurwisa moto, mwero wakazara wekuyerera kwemoto haufanire kudarika UL yakayerwa kuyerera kwevhavha.
Pasinei nekuedza kwakanyanya, kushanda kwakajairwa uye zvisingadzivisike zvekunze zvitubu (zvakadai semarara akawandisa mumvura) zvinogona kukonzera kuti muvharidzi wekumashure apfeke. Iyo inodzivirira yekudzokera shure inoda kuchengetedzwa, iyo inofanirwa kuitwa nenyanzvi yeplumber.
Pane zvinhu zvakawanda zvekufunga nezvazvo pakusarudza yekudzosera inodzivirira: Zviri nyore sei kuwana mukati mezvikamu? Zvikamu zvinogona kugadziriswa zvakasiyana here? Anowanikwa chero nguva here? Zvikamu zvakaita sevharuvhu yekumanikidza kana kuvhara-vharuvhu zvingabviswa here kuti zvigadziriswe kana kutsiviwa? Iyo yakanyanya kuoma kugadzirisa uye iyo yakareba inotora, iyo inokwira mutengo wekugadzirisa.
Mamiriro ekushandisa achave nemhedzisiro yakakura padhizaini, kuiswa uye bhajeti rehurongwa. Zviremera zvemunharaunda zvine masimba pamusoro pemhando dzemavharuvhu anoshandiswa mumhando yega yega yekushandisa. Iyo yakazara urefu hwevhavha kazhinji inogona kuwanikwa mune yehunyanzvi data sheet inopiwa nemugadziri, iyo yakakosha pakutsiva iyo iripo application. Kana nzvimbo iri pa premium, inogona zvakare kukanganisa kuisirwa kutsva.
Mudziyo wacho uchange uri munzvimbo ipi? Semuenzaniso, decompression zone zvikamu zvinogona kusashandiswa mumatangi epasi pevhu kana makomba nekuti anogona kunge akanyura. Uyewo funga nezvemamiriro ekunze iyo valve ichave yakaratidzwa uye kuti ichakanganisa sei zvikamu zvakafumurwa.
Chinhu chinorema chekusarudzwa kwemidziyo inonyanya kukosha kwevashandi vane chekuita nekubata uye kuisa. Mukuwedzera, tapota funga kuti inogadzirwa nezvinhu zvipi. Zvinhu zvakaumbwa uye simbi isina tsvina zvinowanzoreruka pane simbi yakakandwa kana ductile iron. Izvo zviduku zviri nani, nokuti zvinogona kusiya nzvimbo yakawedzerwa kune mavharuvhu anodiwa zvikuru muhurongwa uye kutora nzvimbo shoma muimba yemuchina.
Midziyo yekudzivirira yekudzokera kumashure inoiswa munzvimbo dzakasiyana siyana, kubva munzvimbo huru dzakavhurika kuenda kumakamuri madiki emakombuta. Iwo akagadzirirwa kubvumidza akawanda ekuisa masisitimu, achigonesa dhizaini mainjiniya kuisa michina munzvimbo. Sarudzo dzekumisikidza dzakachinjika [zvakawanda], dzakamira, "N" mhando uye "Z" mhando.
Kazhinji kutaura, mashandiro evharuvhu anenge asina kuchinjika maererano nekumisikidza kwayo; zvisinei, unofanira nguva dzose kuverenga mugadziri wacho ruzivo ruzivo uye kubvunza yomunharaunda pombi dzemvura bumbiro mukuru usati waita kutenga chisarudzo.
Nzira yekuedza valve inobva pane zvinodiwa nedhipatimendi remvura yemunharaunda, asi valve pachayo ichakanganisa kuoma kwekuedzwa kwevhavha uye kugadzirisa dambudziko. Muongorori anofanirwa kushandisa jongwe rekuyedza kuti anyatso kuyedza basa remidziyo. Kana iyo valve ine mvumo yakakwana kumativi ose, izvi kazhinji hazvisi dambudziko, asi kana izvi zvisingabviri (kuputsa mazano emugadziri) kana kana valve ichishandurwa, rusvingo kana mapaipi aripo anogona kuita kuti zvive zvakaoma kana zvisingakwanisi kupinda Test. jongwe-izvi zvichaita kuti re-pombi kana zvakakwana vharafu kutsiva.
Mukuwedzera pakuedza valve, kumwe kushandiswa kwejongwe rekuedza ndeyekutsvaira valve mukuedza kubvisa tsvina inogona kusvibisa kuongorora. Jongwe rakakura rekuyedza rinobvumira kuyerera kwakawanda, nekudaro kuwedzera mikana yako yekubvisa marara. Kuti uedze uye ugadzirise vharafu, zvakakosha kuti kanenge vharafu yekuvhara yakadzika yakavharwa zvakasimba uye isina kubuda. Nokuda kwechikonzero ichi, kuvharwa kwepamusoro-soro chikamu chinokosha chezvikamu zvekudzoka, uye kukwanisa kuzvigadzirisa kuita kuti valve ionekwe zvakare inokosha zvakare.
Paunenge uchitsanangura chinodzivirira chekudzokera shure, pane zvakawanda zvingasarudzwa zvevhavhavha yekuvhara iripo, kusanganisira: Mavharuvhu ebhora-anowanzo shandiswa 2-inch assemblies. Uye inobvumira kuvhura nyore kana kuvhara kwe ¼ giya; butterfly valve-apo kupfupika kudiki kunodiwa, inogona kuvharwa zvishoma nezvishoma nekushanda kwegiya kudzivirira sando yemvura (chinodiwa chekudzivirira moto), kana kutonga kwemagetsi; NRS [dzinde isiri yakatwasuka] Gedhi vharuvhu-yakanaka kana usina gwapa pamusoro pegumbo reruoko uye usingade kuratidzwa kwechinzvimbo (kuvhura / kuvhara); OSY [dzinde rekunze nejoko] gedhi vharafu-iyo yakajairwa dhizaini yemavharuvhu emoto makuru-dhayamita, nekuti Dzinde revharuvhu rinosimuka rinopa chiratidzo chekuona chinzvimbo uye chinogona kuiswa netamper switch; PIV [Column Indicator Valve] -kazhinji isarudzo yeNRS mavharuvhu egedhi, mavharuvhu aya akagadzirwa kuti abatanidzwe nekoramu inozoratidza zvinooneka ” “Vhura” kana “yakavharwa” uye anowanzo shandiswa mukudzivirira moto masisitimu kana vharafu isiri. svikika, sepasi pevhu kana kuseri kwemadziro.
Izvo zvakakosha kuti unzwisise yako yekwaunogara mirau uye zvinodiwa, nekuti chishandiso chinogona kubvumidzwa kushandiswa mukushandisa mune imwe nzvimbo, asi ichionekwa isina kukwana munzvimbo inotevera. Zvinokurudzirwa kuchengetedza hukama nemuongorori wepombi yenzvimbo yako uye dhipatimendi remvura kuitira kuti udzivise kutadza kwekuongorora kana kuisa michina inodhura kana michina yehupfumi ikasangana nezvinodiwa.
Pane zviwanikwa zvekupa ruzivo, dzidzo, kuyedzwa kwechigadzirwa uye chitupa, kuvaka kuongororwa kwechigadzirwa, uye rubatsiro rwekuvandudza kodhi. Masangano aya anogona kubatsira: IAPMO-International Association of Plumbing and Machinery Officials (IAPMO) iapmo; USC Cross-Connect Control uye Hydraulic Research Foundation, fccchr.usc.edu; uye American Society of Sanitary Engineers (ASSE), asse-plumbing.org.
Plumbers, makondirakiti, uye mainjiniya vane dzimwe sarudzo dzekuziva, kuronga nekudzivirira zvingangoitika zvekudzokera kumashure zvisati zvaitika, asi kuchinja mapiping maratidziro uye yakaoma pombi masisitimu anoita kuti zviome kufamba. Kutsanangura iyo chaiyo yekudzivirira yekudzokera shure ndiyo nhanho yekutanga mune yakachengeteka uye yakavimbika mvura inopihwa.
