Ini Makumi maviri neshanu taboo yekumisikidza midziyo yakaoma valve, yakawanda sei yaunoziva?

Valve ndiyo inonyanya kushandiswa mumabhizinesi emakemikari. Zvinoita sezviri nyore kuisa valve, asi kana ikasaitwa maererano nekombiyuta yakakodzera, inokonzera njodzi dzekuchengetedza. Nhasi, ndinoda kugovera ruzivo uye ruzivo nezve kuiswa kwevhavha. Taboo 1 Mvura yekumanikidza bvunzo ichaitwa pasi pekupisa kwakashata panguva yekuvaka kwechando. Mhedzisiro: nekuda kwekukurumidza kutonhora mupombi panguva yekuyedzwa kwe hydrostatic, pombi yakaomeswa Matanho: bvunzo yekumanikidza mvura ichaitwa isati yasvika nguva yechando kuvakwa zvakanyanya sezvinobvira, uye mvura ichapeperetswa yakachena mushure mekudzvanywa bvunzo, kunyanya. mvura iri muvharuvhu inofanira kucheneswa, kana zvisina kudaro vharafu ichaita ngura kana yakareruka, uye inoomesa nechando kana ichirema. Munguva yekuedzwa kwemvura munguva yechando, purojekiti ichaitwa pasi pekushisa kwakanaka kwemukati, uye mvura ichaputirwa yakachena mushure mekuedzwa kwekumanikidza. Taboo 2 Iyo pombi system haina kugezwa zvakanaka isati yapera, uye kuyerera nekumhanya hazvigone kuzadzisa zvinodiwa pakutsvaira kwepombi. Inotoshandisa iyo hydraulic simba bvunzo kudhiza mvura pachinzvimbo chekutsvaira. Mhedzisiro: kana hutano hwemvura hukakundikana kuzadzisa zvinodiwa zvekushanda kwepipeline system, chikamu chepombi chichaderedzwa kana kuvharwa. Matanho: flush neyakagadziriswa muto wekuyerera kana mwero wekuyerera kwemvura isiri pasi pe3m / s muhurongwa. Ruvara rwemvura uye kujeka kwekubuda kunopindirana neiyo yekupinza kuburikidza nekutarisa kwekuona. Taboo 3 Sewage, mvura inonaya uye pombi dzecondensate dzinofanira kuvanzwa pasina kuvharwa mvura bvunzo. Mhedzisiro: inogona kukonzera kubuda kwemvura uye kurasikirwa nemushandisi. Matanho: bvunzo yemvura yakavharwa ichatariswa uye inogamuchirwa zvakanyatsoenderana nezvinodiwa. Kuisa pasi pevhu, sirin'i, kamuri yepombi nemamwe mapombi akavigwa, mvura inonaya, pombi dzecondensate, nezvimwewo zvichavimbiswa kuti hazvibvisi. Taboo 4 Munguva yekuyedzwa kwesimba re hydraulic uye tightness bvunzo yepombi system, chete kukosha kwekumanikidza uye shanduko yemvura inocherechedzwa, uye kuongororwa kwekudonha hakuna kukwana. Mhedzisiro: kuvuza kunoitika mushure mekushanda kwepombi system, inokanganisa kushandiswa kwakajairwa. Matanho: kana iyo pombi system yakayedzwa zvinoenderana nezvinodiwa zvekugadzira uye zvirevo zvekuvaka, kunze kwekurekodha kukosha kwekumanikidza kana shanduko yemvura mukati menguva yakatarwa, zvinodikanwa kunyatso tarisa kana paine kuvuza. Taboo 5 Yakajairwa vharafu flange inoshandiswa kune butterfly valve flange. Mhedzisiro: saizi yeshavishavi valve flange yakasiyana neiyo yakajairika valve flange. Imwe dhayamita yemukati yeflange idiki, nepo vharuvhu yevharuvhu yevharuvhu yakakura, izvo zvinoguma nekutadza kuvhura kana kuvhurika kwakaoma uye kukuvadza vharafu. Zviyero: iyo flange ndiro ichagadziriswa zvinoenderana nehukuru chaihwo hwe butterfly valve flange. Taboo 6 Iko hakuna maburi akachengetwa uye zvikamu zvakadzimirirwa mukuvakwa kwechivako chekuvaka, kana saizi yemakomba akachengetwa idiki uye zvikamu zvakadzimirirwa hazvina kunyorwa. Mhedzisiro: mukuvakwa kweinjiniya inodziya uye yehutsanana, kupenengura chimiro chekuvaka, kunyangwe kucheka masimbi akasimbiswa, kunokanganisa kuchengetedzwa kwechivakwa. Matanho: kujairana nemadhirowa ekuvaka eiyo yekudziya uye yehutsanana purojekiti, kushingaira uye nekungwarira kushandira pamwe nekuvakwa kwechivako chekuvaka kuchengetedza maburi uye zvikamu zvakadzimirirwa zvinoenderana nezvinodiwa zvekuiswa kwepombi uye zvitsigiro uye hangers, uye tarisa kune iyo dhizaini zvinodiwa uye zvirevo zvekuvaka kune ruzivo. Taboo 7 Panguva yekubatanidza pombi, mushure mejoinhi yepombi, iyo yakadzedzereka yejoint yepombi haisi pamutsetse wepakati, hapana gapu rinosiiwa pajoinhi yebutt, hapana groove rakachekwa pombi yemadziro gobvu, uye hupamhi nekureba kweweld hazvisangana zvinodikanwa zvezvimiro zvekuvaka. Mhedzisiro: kana pombi isiri mumutsara wepakati, ichakanganisa zvakananga kunaka kwekushongedza uye kutaridzika kwemhando. Hapana gaka richasiiwa kune bhuti yejoint, hapana groove ichachekwa kune gobvu madziro pombi, uye kana hupamhi nekukwirira kweweld zvisingaite zvinodiwa, welding haigone kusangana nezvinodiwa zvesimba. Zviyero: mushure mekubatanidzwa kwebutt yepipe yakasungirirwa, pombi haifaniri kuzununguswa uye inenge iri pamutsara wepakati; chibatanidzo chechiuno chinofanira kupiwa mvumo; pombi gobvu yorusvingo ngaiberere. Mukuwedzera, hupamhi uye urefu hwe weld huchave wakashongedzwa maererano nekutsanangurwa. Taboo 8 Iyo pombi inovigwa zvakananga muvhu rakaoma nechando uye isina kucheneswa ivhu, uye nzvimbo nenzvimbo yepombi mabhoti hazvina kunaka, kunyangwe muchimiro chezvidhinha zvakaoma. Mhedzisiro: iyo pombi yakakuvadzwa mukuita kwekudzosera kumashure compaction nekuda kwerutsigiro rusina kugadzikana, zvichikonzera rework uye kugadzirisa. Matanho: pombi haizovigwa paivhu rakaomeswa nechando uye isina kucheneswa ivhu. Chinhambwe chiri pakati pemabhurosi chinosangana nezvinodiwa zvekuvaka, uye padhi yekutsigira ichave yakasimba, kunyanya papipeline interface, isingaite simba rekugera. Zvidhinha zvidhinha zvichavakwa nedhaka resimende kuti zvive nechokwadi uye kusimba. Taboo 9 Zvinhu zvebhaudhi yekuwedzera yekugadzirisa pombi inotsigirwa haina kunaka, gomba rekuisa bhaudhi rekuwedzera rakakurisa kana bhoti yekuwedzera yakaiswa pamadziro ezvidhinha kana kunyange madziro emwenje. Mhedzisiro: tsigiro yepombi yakasununguka, pombi yakaremara kana kutodonha. Matanho: zvigadzirwa zvinokodzera zvinofanirwa kusarudzirwa mabhoti ekuwedzera. Kana zvichidikanwa, samples dzinotorwa kuti dziongororwe uye dziongororwe. Iyo dhayamita yegomba yekuisa mabhaudhi ekuwedzera haifanire kunge yakakura kupfuura 2mm yedhayamita yekunze yemabhaudhi ekuwedzera. Mabhaudhi ekuwedzera achaiswa kune zvivakwa zvekongiri. Taboo 10 Simba reflange ndiro uye gasket yekubatanidza pombi haina kukwana, uye bhaudhi yekubatanidza ipfupi kana dhayamita itete. Rubber pad ichashandiswa pakupisa pombi, kaviri-layer pad kana bevel pad ichashandiswa pombi yemvura inotonhora, uye flange pad ichabuda mupombi. Mhedzisiro: iyo flange yekubatanidza haina kusimba, kunyange yakakuvadzwa, uye kuvuza kunoitika. Kana iyo flange gasket ichikwira mupombi, inowedzera kuyerera kwekudzivirira. Matanho: iyo flange ndiro uye gasket inoshandiswa pombi yepombi inofanirwa kusangana nezvinodiwa zvedhizaini yekushanda kumanikidza kwepombi. Rubber asbestos pad ichashandiswa kune flange gasket yekupisa uye pombi dzemvura inopisa; rubber pad ichashandiswa kune flange gasket yemvura yekupa uye pombi dzemvura. Iyo gasket yeflange haingapindi mupombi, uye denderedzwa rekunze richave rakakodzera kune gomba rebhoti reflange. Hapana padhi yakatemerwa kana mapedhi akati wandei achaiswa pakati peflange. Iyo dhayamita yebhaudhi inobatanidza flange ichave isingasviki 2mm pane iyo flange gomba dhayamita, uye kureba kweiyo nut inobudikira yebhoti tsvimbo ichave 1/2 yehukobvu hwenzungu.
