Vharuvhu yeBhatafurayi Nhanganyaya

Nhanganyaya:

Vharuvhu yeshavishavianobva kumhuri yemavharuvhu anonzimavharuvhu ekutenderera kwekota. Pakushanda, vharuvhu rinovhurwa zvizere kana kuvharwa kana dhisiki ikatenderedzwa kota yekutenderera. "Shashava" idhisiki yesimbi yakasungirirwa padanda. Kana vharuvhu yakavharwa, dhisiki inotenderedzwa kuitira kuti ivhare zvachose nzira. Kana vharuvhu yavhurwa zvizere, dhisiki inotenderedzwa kota yekutenderera kuitira kuti ibvumire nzira isina muganho yemvura. Vharuvhu inogonawo kuvhurwa zvishoma nezvishoma kuti ifambe zvakanaka.

Kune mhando dzakasiyana dzemavharuvhu eshavishavi, rimwe nerimwe rakagadziriswa kumanikidzwa kwakasiyana uye kushandiswa kwakasiyana. Vharuvhu yeshavishavi yezero-offset, inoshandisa kuchinjika kwerabha, ine chiyero chakaderera chekumanikidzwa. Vharuvhu yeshavishavi yedouble offset inoshanda zvakanyanya, inoshandiswa mumasisitimu ekumanikidzwa akakwira zvishoma, inobviswa kubva pakati pechigaro chediski nechisimbiso chemuviri (offset one), uye pakati pebhore (offset two). Izvi zvinogadzira chiito checam panguva yekushanda kwekusimudza chigaro kubva muchisimbiso zvichikonzera kukweshana kushoma pane kunogadzirwa mukugadzirwa kwezero offset uye kunoderedza katsika kacho kekupfeka. Vharuvhu yakakodzera masisitimu ekumanikidzwa kwakanyanya ivharuvhu yeshavishavi yetriple offset. Muvharuvhu iyi axis yekubatana kwechigaro chediski inobviswa, iyo inoshanda kubvisa kutsvedza pakati pedhisiki nechigaro. Kana iri mavharuvhu etriple offset, chigaro chakagadzirwa nesimbi kuitira kuti chigone kugadzirwa kuitira kuti chivharwe zvakasimba kana chasangana nedhisiki.

Mhando

1. Mavharuvhu eshavishavi akasimba- rudzi urwu rwevharuvhu rune chigaro cherabha chinogara kwenguva refu chine dhisiki resimbi.
2. Mavharuvhu eshavishavi ane mavara maviri(mavharuvhu eshavishavi anoshanda zvakanyanya kana mavharuvhu eshavishavi maviri) - mhando dzakasiyana dzezvinhu zvinoshandiswa sechigaro nedhisiki.
3. Mavharuvhu eshavishavi ane mavara matatu (Triply-eccentric butterfly valves)(mavharuvhu eshavishavi matatu) - zvigaro zvacho zvakagadzirwa nelaminate kana kuti simbi yakasimba.

Mavharuvhu eshavishavi akaita sewafer

Iyovharuvhu yemhando yeshavishavi yewaferYakagadzirirwa kuchengetedza chisimbiso chinodzivirira musiyano wekumanikidzwa kwemativi maviri kudzivirira chero kudzokera shure mumasisitimu akagadzirirwa kuyerera kwemativi ese. Inoita izvi nechisimbiso chakasimba; kureva, gasket, o-ring, machined chaiyo, uye vharafu rakatsetseka kumativi evharuvhu kumusoro nekuzasi.

Vharuvhu yeshavishavi yakaita seLug

Mavharuvhu akaita seLugine tambo dzinoiswa pamativi ese emuviri wevharuvhu. Izvi zvinovabvumira kuiswa musystem uchishandisa mabhoti maviri uye pasina nzungu. Vharuvhu inoiswa pakati pemaflange maviri uchishandisa seti yakasiyana yemabhoti eflange yega yega. Kugadziriswa uku kunobvumira divi rega rega resystem yepombi kuti ribviswe pasina kukanganisa rimwe divi.

Vharuvhu yeshavishavi yakaita selug inoshandiswa mu dead end service inowanzova ne pressure rating yakaderera. Semuenzaniso, vharuvhu yeshavishavi yakaita selug yakaiswa pakati pemaflange maviri ine pressure rating ye1,000 kPa (150 psi). Vharuvhu imwecheteyo yakaiswa neflange imwe, mu dead end service, ine 520 kPa (75 psi). Mavharuvhu akasungirirwa anodzivirira zvakanyanya kumakemikari uye zvinonyungudutsa uye anogona kubata tembiricha inosvika 200 °C, izvo zvinoita kuti ive mhinduro inoshanda zvakasiyana-siyana.

Shandisa muindasitiri

Mumaindasitiri emishonga, makemikari, uye chikafu, vharuvhu yemapuruguru inoshandiswa kukanganisa kufamba kwechigadzirwa (chakasimba, chemvura, chegasi) mukati mekuita uku. Mavharuvhu anoshandiswa mumaindasitiri aya anowanzo kugadzirwa zvichienderana nemirairo ye cGMP (maitiro akanaka ekugadzira aripo parizvino). Mavharuvhu emapuruguru anowanzo tsiva mavharuvhu emabhora mumaindasitiri mazhinji, kunyanya peturu, nekuda kwemutengo wakaderera uye nyore kuisa, asi mapaipi ane mavharuvhu emapuruguru haagone 'kuiswa' kuti acheneswe.
