ZVINOTAURWA

Zvimiro zveDhizaini:

1. Mapuriro maviri kana kuti Mapuriro rimwe chete

2. Wafer, Lug uye Flanged

3. Zvisina Kuchengetedzwa uye Zvichengetedzwe

Vharuvhu yekuongorora mapurasitiki maviri (API 594) inoshandiswa pamapaipi akachena uye emaindasitiri, kuchengetedzwa kwezvakatipoteredza, kurapwa kwemvura, kupihwa kwemvura uye mapaipi emvura muzvivakwa zvakakwira kudzivirira kuyerera kwemagetsi kubva pakudzokera shure. Vharuvhu yekutarisa inoshandisa rudzi rwewafer, plate yeshavishavi ine ma semicircles maviri, uye inoshandisa chitubu kuti itangezve, nzvimbo yekuvhara inogona kunge iri yekushongedza muviri, isingaparadzike kana rabha, nzvimbo yekushandisa yakafara, uye kuvharwa kwayo kwakavimbika.

Zvikamu zvekuvhura nekuvhara zveAPI 594 check valve zvinoenderana nekuyerera nesimba remedium kuti ivhurike kana kuvhara yega kudzivirira medium kuti isadzokere shure. Vharuvhu iyi inonzi check valve. Mavharuvhu echeki ndeemuboka remavharuvhu e otomatiki, ayo anonyanya kushandiswa mumapaipi uko medium inoyerera ichienda kune rimwe divi, uye anongobvumira medium kuti ifambe ichienda kune rimwe divi kudzivirira tsaona.

Zvichienderana nechimiro chevharuvhu yekutarisa, inogona kukamurwa kuita mhando nhatu:vharuvhu yekutarisa kusimudzira, vharuvhu yekutarisa swinguyevharuvhu yekutarisa waferMavharuvhu ekuongorora anokwidziridzwa anogona kukamurwa kuita mhando mbiri: dzakamira nedzakatambarara. Mavharuvhu ekuongorora anotenderera akakamurwa kuita mhando nhatu: vharuvhu imwe chete, vharuvhu mbiri uye vharuvhu dzakawanda. Vharuvhu yekuongorora yewafer imhando yakatwasuka. Vharuvhu yekuongorora ivharuvhu inogona kudzivirira mvura kuti isayerere ichidzokera shure. Vharuvhu yevharuvhu yekuongorora inovhurwa nekumanikidzwa kwemvura, uye mvura inoyerera ichibva parutivi rwekupinda ichienda parutivi rwekubuda. Kana kumanikidzwa kuri parutivi rwekupinda kwakaderera pane kuri parutivi rwekubuda, vharuvhu inovharwa yega nekuda kwekusiyana kwekumanikidzwa kwemvura, simba rinokwevera pasi nezvimwe zvinhu zvinodzivirira mvura kuti isayerere ichidzokera shure.

Kana muchida rumwe ruzivo nezve mavharuvhu ndapota taurai nebazi rekutengesa reNSW (newsway valve)

Ruzivo rwehunyanzvi rwemavharuvhu ekuongorora eAPI 594

Chii chinonzi API 594 Standard

API 594, yakavambwa neAmerican Petroleum Institute (API), ndiyo chiyero cheindasitiri chine zita rekuti “Check Valve: Flanged, Lug, Wafer, uye Butt-welding Types.” Iyi tsananguro yakakosha inodzora dhizaini, kusarudzwa kwezvinhu, saizi yechimiro, kushivirira kumanikidzwa nekupisa, uye maitiro ekuongorora/kuyedza mavharuvhu ekuongorora eindasitiri.

Kuwanda & Kushandiswa kweAPI 594

API 594 inoshanda kune ese ari maviri mavharuvhu ekutarisa erudzi rweA (pfupi-kutarisana) uye erudzi rweB (refu-kutarisana) . Inosanganisira zvakakwana magadzirirwo akasiyana-siyana ezvimiro, anosanganisira:

• Mavharuvhu Ekutarisa Kutenderera
• Mavharuvhu Ekutarisa Kusimudza
• Vharuvhu Yekutarisa Mapuratifomu Aviri /Vharuvhu Yekutarisa Yechikafus
• Mavharuvhu Ekuongorora Shavishavi
  Mutemo uyu unoshanda kune saizi dzemavharuvhu kubva paDN 150 (NPS 6) kusvika paDN 400 (NPS 16). Unodzora mavharuvhu akagadzirwa nezvinhu zvakaita sesimbi yakakandwa yegrey, simbi yakapfava, simbi yakakangwa, simbi isingatsvedzeri, nezvimwe zvinhu.

Zvinodiwa pakugadzira nekushandisa API 594

• Kutevedzera Dhizaini: Dhizaini yevharuvhu inofanira kunyatsotevedzera zvinodiwa neAPI 594.
• Maitiro Ekubatanidza: Kubatanidza kwekupedzisira (flanged, lug, wafer, butt-weld) kunofanirwa kuenderana nehukuru uye zviyero zvakatsanangurwa mumatanho anotsanangurwa seASME B16.11 (Socket Welding & Threaded) uye ASME B16.15 (Cast Bronze Threaded Fittings - Class 125 & 250).
• Kusarudzwa Kwezvinhu: Zvinhu zvinobvumidzwa zvinosanganisira simbi yakakandwa yegrey, simbi yakapfava, simbi yakakangwa, simbi isingatsvedzeri, uye alloys dzakasiyana-siyana. Chinonyanya kukosha ndechekuti, zvinhu zvinovhara pamusoro zvinofanira kunge zvinoenderana nechinhu chaicho chebasa kuti zvive nechokwadi chekuti zvakachengeteka uye kudzivirira ngura kana kuora.

Maitiro eVharufu & Nzira dzekubatanidza

API 594 inoronga mavharuvhu zvichienderana nekubatana kwawo kwekupedzisira:

• Rudzi rweFlanged: Inoshandisa magumo ane flanges ekubatanidza mabhoti kuma flanges epombi. Yakanakira masisitimu emapaipi eflanges akajairwa anoda nyore kubatanidza/kuputsa.
• Rudzi rweMatako: Rune magumo akachekwa ekunamira zvakananga kupombi. Yakagadzirirwa kushandiswa pakupisa kwakanyanya, kumanikidzwa kwakanyanya, kana kushandiswa kwakakosha uko kusimba kwekudonhedza mvura kwakanyanya kukosha.
• Rudzi rweLug: Rinosanganisira ma threaded inserts (lugs) pamuviri wevharuvhu, zvichiita kuti kuiswa pakati pema flanges kushandise ma bolts kuburikidza nema lugs, zvakakodzera kushandiswa zvisina kunaka.
• Rudzi rweWafer: Inopa dhizaini diki, yakareruka yakaiswa pakati pemaflanges ichishandisa mabhaudhi marefu anotenderera pombi yese. Inoshanda zvakanaka pakuisa mapaipi emaindasitiri.

Kuyera Kudzvanywa-Tembiricha

API 594 inotsanangura zvakajeka kuyera kwekupisa-kumanikidzwa (PT) kwemavharuvhu ekutarisa zvichibva pane zvinhu, dhizaini, uye saizi. Kuyera uku kunovimbisa kuti vharuvhu inogona kushanda zvakachengeteka uye zvakavimbika pasi pemamiriro ekupisa nekumanikidzwa kwakatarwa muhupenyu hwayo hwese hwekushanda. Vagadziri nevashandisi vanofanirwa kutevedzera zvakanyanya miganhu iyi yePT.

Zvinodiwa zveKuongorora & Kuyedza

Mavharuvhu ese eAPI 594 anoongororwa nekuongororwa kuti aone kuti mashandiro awo anoshanda zvakanaka uye akavimbika. Maitiro ekuyedza anotevedzera mitemo yeindasitiri zvakanyanya, kunyanya:

• API 598: Kuongorora neKuedza Vharuvhu (inosanganisira bvunzo dzemagoko, bvunzo dzezvigaro, bvunzo dzezvigaro zvekumashure, nezvimwewo).
• ASME B16.10: Kureba kweMavharuvhu Kutarisana Uye Kureba kweMavharuvhu.
  Miedzo mikuru inosanganisira:
• Kuedza Simba reShell: Kunoongorora kusimba kwemuviri uye kuvimbika kwebhoneti.
• Kuedzwa kwekudonha kwechigaro: Kunosimbisa kugona kwekuvhara kwechinhu.
• Bvunzo reKuvhara Rine Pressure Yakanyanya: Rinovimbisa kuvharwa pasi pekumanikidzwa kwakayerwa.
• Bvunzo reKuvhara Risina Kumanikidzwa: Rinovimbisa kuvharwa pasi pekumanikidzwa kushoma.
• Kuedza Kugara Kumashure (kana zvichibvira): Kunosimbisa kuvharwa kwesimbi pasi pekumanikidzwa kana vharuvhu yavhurika zvizere.
