Ivhavhavhavhavhavhavhavharuru inotenderera muchimiro chenhengo inovhara kana plunger. Nekutenderedza 90 madhigirii, chiteshi chechiteshi pavharuvhu plug yakafanana kana kupatsanurwa kubva pachiteshi chevhavha pamutumbi wevharuvhu, kuitira kuti uone kuvhurwa kana kuvhara kwevharuvhu.
Chimiro chepulagi yevhavhavhavha inogona kuva cylindrical kana conical. Mune cylindrical valve plugs, ndima dzinowanzoita rectangular; mune conical valve plugs, ndima dzacho dziri trapezoidal. Aya maumbirwo anoita kuti chimiro chevhavha yeplug chive chiedza, asi panguva imwe chete, chinoburitsawo kumwe kurasikirwa. Mavharuvhu epuragi akanyanya kukodzera kuvhara uye kubatanidza midhiya uye yekuchinjisa, asi zvichienderana nemhando yekushandiswa uye kushorwa kwekunyungudika kwenzvimbo yekuisa chisimbiso, anogona zvakare kushandiswa kupuruzira. Shandura plug newachi kuti mugodhi uenderane nepombi kuti uzaruke, wotendeutsa plug 90 degrees counterclockwise kuti mugodhi uenderane nepombi kuvhara.
Mhando dzemavharuvhu eplug dzinonyanya kukamurwa muzvikamu zvinotevera:
1. Yakasimbiswa plug valve
Tight-type plug mavharuvhu anowanzo shandiswa mune yakaderera-kudzvanya yakatwasuka-kuburikidza nemapaipi. Kuisa chisimbiso kunoenderana zvachose nekukodzera pakati peplug nemuviri weplug. Kudzvinyirirwa kwechisimbiso chepamusoro kunowanikwa nekusimbisa nut yakaderera. Kazhinji inoshandiswa kuPN≤0.6Mpa.
2. Packing plug valve
Packed plug valve ndeyekuwana plug uye plug yekuisa chisimbiso chemuviri nekumanikidza kurongedza. Nekuda kwekurongedza, kuita chisimbiso kuri nani. Kazhinji rudzi urwu rwevharuvhu yeplug ine gland yekurongedza, uye plug haidi kubuda kubva kumuviri wevharuvhu, nekudaro ichidzikisa nzira yekuvuza yepakati yekushanda. Iri rudzi rwe plug valve rinoshandiswa zvakanyanya kumanikidza kwePN≤1Mpa.
3. Self-sealing plug valve
Iyo yekuzvivharira plug valve inoziva iyo compression chisimbiso pakati peplug nemuviri weplug kuburikidza nekumanikidza kwepakati pachayo. Mugumo mudiki weplug unokwira kumusoro kunze kwemuviri, uye yepakati inopinda muhombe yeplug nepaburi diki painopinza, uye plug inotsikirirwa kumusoro. Ichi chimiro chinowanzo shandiswa kune mhepo media.
4. Mafuta-akavharwa plug valve
Mumakore achangopfuura, huwandu hwemashandisirwo emavharuvhu epulagi hwakaramba huchiwedzerwa, uye mavharuvhu akavharwa-akavharwa neoiri ane kumanikidzirwa akaonekwa. Nekuda kwekumanikidzwa kwekuzora, firimu remafuta rinoumbwa pakati pechisimbiso chepamusoro peplug nemuviri weplug. Nenzira iyi, kuiswa chisimbiso kuri nani, kuvhura nekuvhara ndiko kuchengetedza basa, uye nzvimbo yekuisa chisimbiso inodzivirirwa kubva pakukuvadzwa. Mune zvimwe zviitiko, nekuda kwezvakasiyana zvinhu uye shanduko muchinjika-chikamu, kuwedzera kwakasiyana kunozoitika, izvo zvinokonzeresa kumwe deformation. Zvinofanira kucherechedzwa kuti kana masuwo maviri akasununguka kuwedzera uye chibvumirano, chitubu chinofanirawo kuwedzera uye kubvumirana nacho.
