Plug Mavharuvhu Vagadziri

Plug valves ivharuvhu inotenderera muchimiro chenhengo yekuvhara kana plunger, iyo inogona kuvhurwa kana kuvharwa nekutenderera 90 madhigirii kuti abatanidze kana kupatsanura chiteshi chechiteshi pavharuvha plug uye chiteshi chevhavha pamutumbi wevharuvhu.

Iyo valve plug inogona kunge yakaita cylindrical kana conical muchimiro. Mune cylindrical valve plug, ndima yacho inowanzoita rectangular; Paunenge uri muconical valve plug, chiteshi chiri trapezoidal. Aya maumbirwo anoita kuti chimiro chevharuvhu yeplug chireruke. Iyo inonyanya kukodzera kucheka uye kubatanidza svikiro uye shunting, asi dzimwe nguva inogona zvakare kushandiswa kupuruzira zvinoenderana neanoshanda zvivakwa uye erosion kuramba kwekuisa chisimbiso.

Iyo plug valve inokurumidza kuvhura uye kuvhara kuburikidza nevharuvhu. Sezvo kufamba pakati pe rotary sealing surfaces kune simba rekupukuta, uye kusangana nemhepo inoyerera inogona kudzivirirwa zvachose kana yakazarurwa zvakakwana, inogonawo kushandiswa kune svikiro nezvikamu zvakamiswa. Chimwe chinhu chakakosha ndechekuti zviri nyore kuchinjika kune akawanda-channel chimiro, kuitira kuti imwe vharuvhu iwane maviri, matatu, kana kunyange mana akasiyana nzira dzekuyerera. Izvi zvinogona kurerutsa dhizaini yepombi system, kuderedza kushandiswa kwemavharuvhu uye zvimwe zvekubatanidza zvinodikanwa mumidziyo.

kushanda musimboti

Ivharuvhu ine plug ine muviri weplug ine buri semuburi. Iyo plug body inotenderera ne [2] vharafu tsvimbo kuti uone kuvhura nekuvhara chiito. Iyo diki plug valve isina kurongedza inonziwo "jongwe". Iyo plug body yevharuvhu yeplug kazhinji ikoni (kana silinda), iyo inobatana neconical gomba pamusoro pemuviri wevharuvhu kuita peya yekuvharisa. Plug valve ndiyo imwe yekutanga mavharuvhu akashandiswa, ane chimiro chakareruka, kukurumidza kuvhura nekuvhara, uye kushoma kwemvura kuramba. Mavharuvhu akajairika anonamirwa nekusangana kwakananga pakati peakapedzwa simbi plug muviri nemuviri wevharuvhu, saka chisimbiso pfuma haina kunaka, kuvhura uye kuvhara simba rakakura, uye zviri nyore kupfeka. Kazhinji, vanogona kungoshandiswa mukudzvinyirira kwakaderera (kwete kukwira kupfuura 1 MPa) uye dhayamita diki (pasi pe100 mm).

Zvinoenderana nechimiro chechimiro, chinogona kupatsanurwa kuita mhando ina: yakagadziriswa plug valve, self sealing plug valve, plug valve uye oiri yekuzadza plug valve. Zvinoenderana neiyo chiteshi fomu, inogona kukamurwa kuita mhando nhatu: yakatwasuka plug valve, matatu-nzira plug valve uye ina-nzira plug valve. Kune zvakare mavharuvhu emhando yeferrule.

Mavharuvhu epuragi akaiswa mumavharuvhu akapfava seal plug, mafuta akaomeswa akaomarara seal plug mavharuvhu, poppet plug mavharuvhu, matatu-nzira uye mana-nzira plug mavharuvhu zvinoenderana nemashandisirwo awo.

Soft seal

Mavharuvhu akapfava seal plug anowanzo shandiswa munzvimbo dzakaoma senge dzinoora, ine muchetura uye ine njodzi midhiya, uko kuvuza kunorambidzwa zvachose, uye uko mavharuvhu asingasvibise midhiya. Muviri wevharuvhu unogona kugadzirwa nekabhoni simbi, alloy simbi uye simbi isina tsvina zvichienderana nekushanda svikiro.

Oil lubricated hard seal

Oil lubricated yakaoma chisimbiso pulagi mavharuvhu anogona kupatsanurwa kwakajairika mafuta lubricated pulagi mavharuvhu uye kumanikidzwa pakati nepakati plug mavharuvhu. Mafuta ekuzora akakosha anoiswa jekiseni kubva pamusoro pemuviri weplug pakati pegomba rakapetwa remuviri wevharuvhu uye muviri weplug kuti ugadzire firimu remafuta kudzikisa kuvhura nekuvhara torque yevharuvhu uye kunatsiridza mashandiro ekuvhara uye hupenyu hwesevhisi. Kumanikidza kwekushanda kunogona kusvika 64mpa, tembiricha yepamusoro yekushanda inogona kusvika 325 madhigirii, uye iyo yakakura dhayamita inogona kusvika 600mm.

Nokusimudza mhando

Kune akawanda maitiro ezvimiro zvepoppet cocks. Iyo poppet majongwe akakamurwa kuita chisimbiso chakapfava uye chakaoma chisimbiso zvinoenderana nezvinhu zvechisimbiso chepamusoro. Nheyo inokosha ndeyokuita kuti jongwe risimuke kana richinge ravhurwa, uye wozoshandura jongwe 90 degrees kuti rizarure zvakakwana valve kuti kuderedze kupesana nekuvhara pamusoro pemuviri wevhavha; Paunenge uchivhara vharafu, shandura jongwe 90 madhigirii kunzvimbo yakavharwa uye wozoidzikisa kuti ibatane nechisimbiso chepamusoro chemuviri wevhavha kuti uwane chisimbiso.

Tee uye cross type

Iwo matatu-nzira uye mana-nzira plug mavharuvhu akakodzera kushandura yepakati kuyerera kutungamira kana kugovera svikiro mumudziyo. Zvinoenderana nezvinodiwa zvemamiriro ebasa, nyoro chisimbiso bushing kana chisimbiso chakapfava, hard seal poppet plug valve inogona kusarudzwa.

Advantage

1. Ivhavha yevhavha inoshandiswa pakushanda nguva dzose, nekukurumidza uye chiedza kuzarura nekuvhara.

2. The plug valve ine diki fluid resistance.

3. Iyo plug valve iri nyore mukugadzirisa, diki muhuwandu hwehuwandu, chiedza muhuremu uye yakakodzera kugadzirisa.

4. Kuita kwakanaka kwekuisa chisimbiso.

5. Haisi kuganhurirwa negwara rekuisa, uye kuyerera kweiyo svikiro kunogona kuve kusingaite.

6. Hapana kudedera uye ruzha rwakaderera.

nzira

Kune mafomu akawanda. Iyo yakajairika kuburikidza nemhando inonyanya kushandiswa kucheka mvura. Iyo nzira-nhatu plug valve uye ina-nzira ina plug valve inoshanda kune fluid inodzosera plug valve. Chikamu chekuvhura uye chekuvhara i cylinder ine maburi, iyo inotenderera yakapoteredza axis perpendicular kune chiteshi, kuitira kuti uwane chinangwa chekuvhura nekuvhara chiteshi.
