Gavhu risati ratorwa, iyo vhezheni yekuedza kweValve uye vhesi yekusimbisa bvunzo inofanira kuitwa pane iyo valve hydraulic test test bench. 20% yemabhasi-ekudzvinyirirwa-kudzvinyirira anofanirwa kuongororwa zvisingaite, uye 100% inofanira kuongororwa kana isina kukodzera; 100% yepakati uye yakakwirira-yekumanikidza mavharu miviri inofanira kuongororwa. Vaya vanowanzoshandiswa vhezheni yekudzvinyirira mvura, Oiri, mhepo, nitrogen yekuyedza nzira dzemavhiri emapepa anosanganisira mavhavha emapendekete ari kuita seanotevera:
Butterfly valve kudzvinyirira nzira
Muedzo wetsimba weiyo pneumatic butterfly terve yakaenzana neiyo yepasi pevhu. Muchiitiko chekuita chisingaenzaniswi chebheruva butter butter butter, iyo svutugadzike inofanira kuunzwa kubva pakupera kwesvikiro, iyo bhururu racho rinofanirwa kuvhurwa, imwe mhedzisiro inofanira kuvharwa, uye kudzvanywa kwejekiseni kunofanira kusvika kukosha kwakataurwa; Mushure mekutarisa kuti hapana kudzvanya pakurongedza uye zvimwe zvisimbiso, vhara iyo butterfly ndiro, vhura imwe mugumo, uye tarisa butterfly vharuvhu. Hapana kubhururuka pachisimbiso chemoyo kwakakodzera. Butterfly vharuvhu rinoshandiswa kudzora kuyerera kunogona kunge kusingaedzwe nekuda kwekuisa chisimbiso.
Dzvinyiriro yekuyedza nzira yekutarisa vheji
Tarisa vhezheni yeValve Test State: Axis yeiyo yekusimudza cheki valve disc iri muchimiro perpendicular kune yakatwasuka; Iyo axis yeiyo swing cheki valve chiteshi uye disc axis iri munzvimbo inosvika kufanana kune mutsara wakakomberedza.
Munguva yekuedzwa kwetsimba, iyo yekuyedza svikiro yakaunzwa kubva kuInteti kune iyo kukosha kwakataurwa, uye imwe mugumo yakavharwa, uye inokodzera kuona kuti muviri wemba uye nevharo cover haina kuvhara.
Muedzo wekusimbisa, svikiro racho rakaziviswa kubva kumagumo emucheto, uye chisimbiso chekupedzisira chinotariswa kumagumo emucheka, uye hapana kudzora pakurongedza uye gasket rakakodzera.
Dzvinyiriro yekuyedza nzira yeGedhi LEVE
Muedzo wetsimba weGesul Valve dzakafanana neiya yepasi pevhu. Kune nzira mbiri dzekuyedza kwemuedzo weGedhi reGesul.
①Vhura gedhi kuti iite kudzvinyirira muValve kusimuka kune kukosha kwakataurwa; Wobva wavhara gedhi racho, tarisa kuti pane kuvheneka pazvisimbiso pamativi ese egedhi, kana kuiswa zvakananga mukova plugha kune kukosha kwakataurwa, tarisa zvisimbiso pamativi ese egedhi. Iyo nzira iri pamusoro inodaidzwa kuti yepakati yekumanikidza kwekudzvinyirirwa. Iyi nzira haifanirwe kushandiswa kumisikidzwa bvunzo pamavha matsime ane zita rezita rine pasi peDN32mm.
②Imwe nzira ndeyekuvhura gedhi kuti iite gadziri yekudzvinyirira yekudzvinyirira inosimuka kune kukosha kwakataurwa; Ipapo vhara gedhi, vhura imwe mugumo wedombo bofu, uye tarisa kana iyo chisimbiso chechiso ichibuda. Wobva wadzokera kumashure udzokorore bvunzo dziri pamusoro apa kusvikira ranyatsogona.
Muedzo wakasimba wekurongedza uye gasket remagamba emagetsi rinofanira kuitwa pamberi pemuedzo wakasimba wegedhi.
Dzvinyiriro yekuyedza nzira yekumanikidza kudzikisira vharuvhu
①Muedzo wetsimba wekumanikidza kudzvinyirira vharuvhu rinowanzo kuungana mushure mekuedzwa kamwe-kamwe-chidimbu, uye kunogona kuedzwawo mushure megungano. Nguva yeTest Test: 1min for Dn <50mm; Kupfuura 2min yeDN65~150mm; Kupfuura 3min for Dn> 150mm.
Mushure mekunge mabhebhi nezvikamu zvakasungwa, shandisai 1.5 times kudzvanywa kwekumanikidza kudzvinyirira vharuvhu, uye kuitisa bvunzo yemhepo.
②Iyo Airtility bvunzo ichaitwa maererano nesvikiro chaiyo yekushanda. Kana uchiedza nemhepo kana mvura, bvunzo pa1.1 times kudzvinyirira. Kana uchiedzwa ne steam, shandisa iyo yakanyanya kushanda kudzvanywa inobvumirwa pasi pekushanda kwekushandira. Musiyano uripo pakati pekumanikidza kwekumanikidza uye kudzvinyirira kunodiwa kuti usave pasi pe 0.2mpa. Nzira yekubvunzwa ndeye: Mushure mekudzvinyirira kweIntel inogadziridzwa, zvishoma nezvishoma gadzirisa iyo screw yeValve, kuitira kuti dzivirire dzinogona kuchinja uye dzichienderera mukati mehuwandu hwepamusoro uye hushoma kukosha, pasina kuhukura kana kuseka. Kune iyo Steam inomanikidza kuderedza vharuvhu, apo iyo inlet inomirirwa kure, iyo vhariru yakavharwa mushure mekunge vharuvhu yakavharwa, uye kudzvinyirira ndiko kudzvinyirira kwakanyanya uye kwakaderera tsika. Mukati me 2min, kuwedzera kwekunze kudzvanywa kunofanirwa kuita zvinodiwa muTafura 4.17-22. Panguva imwecheteyo, pombi kuseri kweValve inofanira kunge iri vhoriyamu inoenderana nezvinodiwa muTafura 4.18 kuti iwanikwe; Kuti mvura uye mhepo inomanikidza kudzikisira mavharuvhu, apo iyo inlet kudzvinyirira ndeye zero, kudzvinyirira kuvharirwa kwevhu kwakavharwa muyedzo wakasimba, uye hapana kudzvanywa mukati memaminitsi maviri anokwanisa.
Dzvinyiriro Yekutarisa Yepasi Pasi Pasi uye Vharuvhu
Kuti uwane bvunzo yeropa yeValve Valve uye vharuvhu rakavharirwa rinowanzoiswa muyedzo yekudzvinyirira, svikiro racho rakavhurika, uye miviri yevharuvhu uye kuvhara vharuvhu kunoratidzwa ziya nekutsvaira. Muedzo wetsimba unogona zvakare kuitwa pachikamu chimwe chete. Iyo testness test ndeye chete yekuvhara-kure nevharo. Munguva yebvunzo, tsinde yemavheni yepasi rose iri muchimiro chenyika, iyo svikiro yakaunzwa kubva kumagumo kubva kuValve disc kune yakaumbwa kukosha, uye kurongedza uye gasket inotariswa; Mushure mekupfuura bvunzo, iyo vheji disc yakavharwa, uye imwe yekupedzisira yakavhurwa kuti itarise kana paine kubhururuka. Kana simba uye kuongororwa kusimba kwevheni kuchaitwa, iyo bvunzo inogona kutanga kuitwa, kudzvinyirira kunoderedzwa kusvika pakukosha kwekutevedzana kwekutevedzera, uye kurongedza uye gasket inotariswa; Ipapo vhesi disc yakavharwa, uye magumo ekunze anovhurwa kuti atarise kana iyo chisimbiso chechiso chinodonha.
Bhora Valve Pressure Test nzira
Muedzo wetsimba weiyo pneumatic bhora vharuvharha inofanira kuitwa mune hafu-yakavhurika mamiriro ebhora vharuvhu.
①Kuyambuka Bhora Valing Luolising Muedzo: Isa vharuvhu mune hafu-yakavhurika nyika, suma svikiro pane imwe mugumo, uye vhara imwe mugumo; Tenderedza bhora kakawanda, vhura iyo yekupedzisira mugumo apo vharuvhu iri mumamiriro akavharwa, uye tarisa maitiro ekuisa chisimbiso pakurongedza uye gasket panguva imwe chete. Hapanofanirwa kunge pasina kubhururuka. Iyo bvunzo yepakati inobva yaunzwa kubva kune imwe mugumo uye bvunzo iri pamusoro inodzokororwa.
②Kuongorora bvunzo yeiyo Yakatemwa Valve: Pamberi pemubvunzo, tenderera bhora kakawanda pasina mutoro, iyo yekuvharirwa kwevharanda yakavharwa, uye svutugadzike yakaziviswa kubva kune imwe mugumo kusvika kune imwe kukosha. Kuitwa chisimbiso kwekupedzisira kwekupedzisira kunoongororwa neyekudzvinyirira geji, uye kurongeka kweiyo yekumanikidza Gauge ndeye 0 Mukati menguva yakatarwa, kana pasina kushungurudzika phenomenon, inokodzera; Wobva waisa iyo bvunzo yepakati kubva kune imwe mugumo, uye dzokorora bvunzo iri pamusoro. Zvadaro, isa vharuvhu mune imwe hafu yehukama, kuvhara zvese zvinopera, uye zadza iyo yemukati yemukati neiyo svikiro. Tarisa kurongedza uye gasket pasi pekudzvinyirirwa kwekuyedza, uye hakuzove nekudzingwa.
③Iyo nhatu-nzira bhora vharuvharuvhu ichaongororwa kusimba pane imwe neimwe nzvimbo.
