Siyanisa kubva kune chimiro

Iyo-chidimbu bhora vharafu ibhora rakasanganiswa, PTFE mhete, uye kukiya nati. Iyo dhayamita yebhora idiki zvishoma pane iyo yepombi, iyo yakafanana neyakakura bhora valve.

Ivhavhavha yebhora-mbiri inoumbwa nezvikamu zviviri, uye chisimbiso chekuvhara chiri nani pane icho chevhavha yebhora-chidimbu. Iyo dhayamita yebhora yakafanana neyepombi, uye zviri nyore kupatsanura pane imwe-chidimbu bhora vharafu.

Ivhavhavha yebhora-zvidimbu zvitatu inoumbwa nezvikamu zvitatu, bhoneti kumativi ose uye muviri wepakati wevharuvhu. Zvidimbu zvitatubhora vharafuyakasiyana ne-two-piece ball valve uye imwe-chidimbu bhora vharafu pakuti iri nyore kupatsanura nekuchengetedza.

Siyana nekumanikidza

Kudzvinyirirwa kwemhando yemhando mitatu yakakwirira kudarika yeimwe-chidimbu uye maviri-chidimbubhora mavharuvhu. Rutivi rwekunze rwevhavha yebhora rematatu-matatu anogadziriswa nemabhoti mana, ayo anoita basa rakanaka mukutsanya. Iyo chaiyo yekukanda mavharuvhu muviri inogona kusvika kune kumanikidzwa kwe1000psi≈6.9MPa. Pakumanikidza kwepamusoro, miviri yevharuvhu yakaumbwa inoshandiswa.

Zvinoenderana nechimiro chevhavha yebhora, inogona kukamurwa kuita:

1. Bhora rinoyangarara vharafu: Bhora revharuvhu yebhora riri kuyerera. Pasi pechiito chekumanikidza kwepakati, bhora rinogona kuburitsa kumwe kutamiswa uye kudzvanya zvine simba panzvimbo yekuisa chisimbiso chekuguma kwekubuda kuti ive nechokwadi chekuti magumo ekubuda akavharwa. Ivhavha yebhora inoyangarara ine chimiro chakareruka uye kuita kwakanaka kwekuisa chisimbiso, asi kuremerwa kwesphere inotakura svikiro rekushanda zvese zvinopfuudzwa kune yekubuda chisimbiso mhete, saka zvinodikanwa kuti utarise kuti chisimbiso chemhete chinogona kumirisana nebasa rekushanda. sphere medium. Ichi chimiro chinoshandiswa zvakanyanya mupakati uye yakaderera kumanikidza bhora mavharuvhu.

2. Fixed ball valve: Bhora revhavha yebhora rinogadziriswa uye harifambi mushure mekudzvinyirirwa. Iyo yakagadziriswa bhora vharafu ine chigaro chevharuvhu inoyangarara. Mushure mekudzvinyirirwa kwepakati, chigaro chevhavha chinofamba, kuitira kuti mhete yekuvhara inotsikirirwa zvakasimba pabhora kuti ive nechokwadi chekuisa chisimbiso. Bearings dzinowanzoiswa pamusoro uye pasi shafts of the sphere, uye torque inoshanda idiki, iyo yakakodzera kune yakakwirira-kumanikidza uye yakakura-diameter mavharuvhu. Kuti uderedze torque yekushanda yevhavha yebhora uye kuwedzera kuvimbika kwechisimbiso, mafuta-akavharwa bhora mavharuvhu akaonekwa. Mafuta ekuzora akakosha akabayiwa pakati penzvimbo yekuvharisa kuti igadzire firimu remafuta, iro rinosimudzira kuita chisimbiso uye kudzikisa torque yekushandisa, ichiita kuti ive yakakodzera kune yakanyanya kudzvanywa. Ball valve ye caliber.

3. Elastic ball valve: Bhora revhavha yebhora rakatsetseka. Zvose bhora uye chigaro chevhavha chisimbiso chemhete chakagadzirwa nesimbi, uye yekuisa chisimbiso chaiyo yakakurisa. Kumanikidzwa kwepakati pachayo hakugone kusangana nezvinodiwa zvekuisa chisimbiso, uye simba rekunze rinofanira kushandiswa. Iri vharafu rakakodzera kupisa kwakanyanya uye yakanyanya kudzvanywa media. Elastic sphere inogadzirwa nekuvhura elastic groove pazasi pemadziro emukati mesphere kuti uwane elasticity. Paunenge uchivhara ndima, shandisa musoro wakaita seweji wehunde yevharuvhu kuti uwedzere bhora uye wodzvanya chigaro chevharuvhu kuti uvhare. Sunungura musoro wakaita seweji usati watenderedza denderedzwa, uye denderedzwa richadzokera kuchimiro chayo chepakutanga, kuitira kuti pave nekamukana kadiki pakati penzvimbo nechigaro chevharuvhu, izvo zvinogona kuderedza kukweshera kwechisimbiso chepamusoro uye torque inoshanda.

Mavharuvhu ebhora anogona kukamurwa kuita yakatwasuka-kuburikidza nemhando, matatu-nzira mhando uye yekurudyi-ekona mhando zvichienderana nenzvimbo yavo yechiteshi. Iyo yekupedzisiramavharuvhu maviri ebhoraanoshandiswa kugovera svikiro uye kushandura mafambiro ekuyerera kwepakati.
