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 nevhavha yebhora rakakura.

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.Ivhavhavha yebhora-matatu yakasiyana kubva kune maviri-chidimbu bhora valve uye imwe-chidimbubhora vharafupakuti zviri nyore kupatsanura nekuchengetedza.

Siyana nekumanikidza

Kupikiswa kwekumanikidzwa kwevhavha yebhora-matatu kwakakwira zvakanyanya kupfuura yeimwe-chidimbu uye maviri-chidimbu bhora 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.Ivhavhavha yebhora inoyangarara ine chimiro chakareruka uye kuita kwakanaka kwekuvhara, asi mutoro wepakati yekushanda pabhora zvese zvinoendeswa kune yekubuda chisimbiso mhete.Naizvozvo, zvinodikanwa kuti utarise kana iyo yekuisa chisimbiso mhete inogona kumira basa rekushanda re spherical 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 mokugamuchira kumanikidzwa kwepakati, chigaro chevhavha chichafamba, kuitira kuti mhete yekuvhara isimbiswe zvakasimba pabhora kuti ive nechokwadi chekuisa chisimbiso.Bearings dzinowanzoiswa pamusoro uye pasi shafts yebhora, uye torque yekushandisa idiki, iyo yakakodzera kune yakakwirira-kumanikidza uye yakakura-diameter mavharuvhu.Kuti uderedze torque yekushanda yevhavha yebhora uye kuwedzera kuvimbika kwechisimbiso, yakavharwa nemafuta yakavharwa bhora.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 valveof caliber.

3. Elastic ball valve: Bhora revhavha yebhora iri elastic.Iyo sphere uye chigaro chevhavha chisimbiso mhete dzakagadzirwa nesimbi, uye chaiyo kudzvanywa kwechisimbiso kwakakura kwazvo.Kumanikidzwa kwepakati pachayo hakugone kusangana nezvinodiwa zvekuisa chisimbiso, uye simba rekunze rinofanira kushandiswa.Iri vharafu rakakodzera kupisa kwepamusoro uye kudzvinyirira midhiya.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 bhora, uye bhora richadzokera kuchimiro charo chepakutanga, kuitira kuti pave nekamukana kadiki pakati pebhora nechigaro chevharuvhu, izvo zvinogona kuderedza kukwenya kwechisimbiso chepamusoro uye torque yekushandisa.

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