Plug valve, vharuvhu inoshandisa plug body ine buri senhengo yekuvhura nekuvhara.Muviri weplug unotenderera netsvimbo yevharuvhu kuti uwane kuvhura nekuvhara chiito, Ivhavhavhavha diki isina kurongedza inozivikanwawo se "jongwe".Iyo plug body yevharuvhu yeplug inowanzoita conical body (inozivikanwawo sesilinda), iyo inobatirana neconical gomba pamusoro pemuviri wevharuvhu kuita peya yekuvharisa.Plug valve ndiyo yekutanga yerudzi rwevharuvhu yakashandiswa, ine chimiro chakareruka, nekukurumidza kuvhura nekuvhara, uye kushoma kwemvura kushomeka.Ordinary plug mavharuvhu anovimba nekusangana kwakananga pakati peyakapedzwa simbi plug muviri uye muviri wevharuvha kuti uvhare, zvichikonzera kusasimba kwekuisa chisimbiso. , yakakwira yekuvhura nekuvhara simba, uye nyore kupfeka.Iwo anowanzo shandiswa chete mune yakaderera (kwete yakakwirira kupfuura 1 MPa) uye diki dhayamita (pasi pe100 mm) maapplication.Kuti uwedzere huwandu hwemashandisirwo evhavhavhavha, akawanda magadzirirwo matsva akagadzirwa.Mafuta anozorwa plug valve ndiyo inonyanya kukosha mhando.Mafuta ekuzora akakosha anoiswa jekiseni kubva pamusoro pemuviri weplug pakati pegomba rakapetwa remuviri wevharuvhu uye muviri weplug kugadzira firimu remafuta kudzikisa kuvhura nekuvhara torque, kunatsiridza kuita chisimbiso uye hupenyu hwebasa.Kumanikidza kwayo kushanda kunogona kusvika 64 MPa, tembiricha yekushanda yakanyanya inogona kusvika 325 ℃, uye iyo yakakura dhayamita inogona kusvika 600 mm.Kune marudzi akasiyana-siyana ekufamba kwemavharuvhu eplug.Iyo yakajairika yakananga kuburikidza nemhando inonyanya kushandiswa kucheka mvura.Mavharuvhu matatu-nzira uye mana-nzira anokodzera fluid reversing plug mavharuvhu.Nhengo yekuvhura uye yekuvhara yevhavhavhavha ivhavha ine perforated cylinder inotenderera nezve axis perpendicular kune chiteshi, nekudaro ichizadzisa chinangwa chekuvhura nekuvhara chiteshi.Plug mavharuvhu anonyanya kushandiswa kuvhura uye kuvhara mapaipi nemidziyo midhiya.
Izvo zvakakosha zvemavharuvhu eplug ndeaya anotevera:
1. Inokodzera kushanda nguva dzose, nokukurumidza uye chiedza kuzarura nekuvhara.
2. Low fluid resistance.
3. Chimiro chakareruka, saizi diki, huremu huremu, uye kugadzirisa kuri nyore.
4. Kuita kwakanaka kwekuisa chisimbiso.
5. Nzira yekuyerera kwepakati inogona kuve isina kufanira, pasinei nekuisa nzira.
6. Hapana kudedera, ruzha rwakaderera.
7. Plug mavharuvhu anogona kupatsanurwa mumarudzi mana maererano nemaitiro avo: tight set plug mavharuvhu, self sealing plug mavharuvhu, kurongedza plug mavharuvhu, uye mafuta jekiseni plug mavharuvhu.Zvinoenderana nemhando yechiteshi, inogona kukamurwa kuita mhando nhatu: yakatwasuka kuburikidza nemhando, nzira nhatu-mhando, uye ina-nzira mhando.
