Mumusangano weJinbin, mavharuvhu mashanu makuru-diameter eccentric butterfly akaongororwa. Zviyero zvadzo DN2200, uye miviri yevharuvhu yakagadzirwa nesimbi inoputika. Varuvhu yega yega yega inoshongedzerwa nemagetsi emagetsi. Parizvino, idzi dzakawandabutterfly valvesakaongororwa uye akagamuchirwa, uye akamirira kurongedza uye kutumirwa.

Kusiyana nemavharuvhu eshavishavi echinyakare (apo dzinde revharuvhu rinopindirana nepakati pefurafura nemuviri wevharuvhu) kana imwe eccentric flanged butterfly vharuvhu (apo chete hunde yevharuvhu inotsauka kubva pakati pendiro yeshavishavi), mavharuvhu eshavishavi ane eccentric kaviri anotora dhizaini yakapetwa kaviri "yetsinde yevharuvhu inotsauka kubva pakati peshavishavi" muviri wevharuvhu".

Chimiro ichi chinoita kuti butterfly plate ingosangana nechigaro chevharuvhu kana yava pedyo nekuvhara panguva yekuvhura nekuvhara. Munguva yese yekurohwa, butterfly plate inoparadzaniswa zvachose kubva pachigaro chevharuvhu, zvakanyanya kuderedza kukwesha nekupfeka kwechisimbiso chepamusoro. Kunyanya mumamiriro ekukura-dhayamita, inogona kudzivirira "kukweshana kwakaoma" pachisimbiso chepamusoro chinokonzerwa neself-weight ye butterfly plate kana kumanikidzwa kwepakati, zvakanyanya kuwedzera hupenyu hwebasa rekuvhara chisimbiso, iyo inowanzopfuura 30% yakareba kupfuura iyo ye single ductile iron butterfly valves.

Iyo butterfly plate yegetsi-diameter yegetsi butterfly valve inotora dhizaini yakagadziridzwa. Kana yakanyatsozaruka, bhobhobhoti ine nzvimbo diki inovharira yepakati uye yakaderera kuyerera kwekudzivirira coefficient, iyo inogona kuderedza kurasikirwa kwesimba kwepombi system. Kune mapaipi makuru-anoyerera ane dhayamita yeDN1000 kana kupfuura (yakadai semataundi emvura emudhorobha mitsara uye simiti yemagetsi inotenderera masisitimu emvura), kushandiswa kwesimba kwepombi set kwakachengetedzwa zvakanyanya.

Iyo vharafu yemuviri zvinhu inogona kusarudzwa kubva kune ductile iron (yemvura yemunisiparati), kabhoni simbi (yemafuta emuindasitiri), kana simbi isina tsvina (yecorrosive media) zvichienderana nehunhu hwepakati. Pamusoro peplate ye butterfly inogona kupfapfaidzwa-welded ne-wear-resistant layer (yakadai se tungsten carbide), iyo inogona kumira kukukurwa kwe media ine zvishoma zvishoma (zvakadai sejecha uye slag). Pakutakura zvinwiwa zvine tsvina sewewage nemadota slurry, hupenyu hwayo hwesevhisi hukapetwa ka2 kusvika ku3 pane hwemavharuvhu eshavishavi.

Iyo yakakura-dhayamitakaviri eccentric butterfly valve, kuburikidza nekuvandudzwa kwemaitiro, yakagadzirisa kuyerera kwekutonga, kuisa chisimbiso uye kushanda kwehupenyu hwemapaipi makuru-diameter. Yakava mhinduro inoshanda kutsiva zvechinyakare gedhi mavharuvhu uye bhora mavharuvhu ari mukuru-kuyerera uye yakaoma svikiro hurongwa mumanisiparati, simba, mvura kuchengetedza, maindasitiri uye dzimwe minda. Inonyanya kukodzera kumamiriro ekushanda kwenguva refu ane hanya nekushandiswa kwesimba uye mari yekugadzirisa.
