Vharuvhu reButterfly imhando yemudziyo wekudzora kuyerera kwemvura une kufamba kwekota-turn rotational, Inoshandiswa mumapaipi kudzora kana kuparadzanisa kuyerera kwemvura (zvinwiwa kana magasi), Zvisinei, Vharuvhu reButterfly remhando yepamusoro uye rinoshanda zvakanaka rinofanira kunge rakagadzirira kuvhara zvakanaka. Mavharuvhu eButterfly ari maviri-directional here? Kazhinji tinoparadzanisa vharuvhu reButterfly kuita mavharuvhu eButterfly Concentric uye vharuvhu reButterfly eccentric.
Tichakurukura nezve concentric butterfly valve bidirectional sezviri pazasi:
Chii chinonzi Concentric butterfly valve?
Vharuvhu yemapuruguru ine concentric inozivikanwa semavharuvhu epuruguru ane resilient seating kana zero-offset, zvikamu zvawo zvinosanganisira: Muviri wemavharuvhu, dhisiki, chigaro, tsinde uye chisimbiso. Maumbirwo evharuvhu yemapuruguru ine concentric idhisiki uye chigaro chakarongwa pakati pevharuvhu, uye shaft kana tsinde iri pakati pedhisiki. Izvi zvinoreva kuti dhisiki inotenderera mukati mechigaro chakapfava, Chigaro chinogona kusanganisira EPDM, NBR Viton Silicon Teflon Hypalon kana elastomer.
Maitiro ekushandisa vharuvhu yeshavishavi inotenderera?
Kugadzirwa kwevharuvhu remapuruguru kuri nyore, kune nzira nhatu dzekushandisa: Lever Handle yehukuru hudiki, Worm Gear box yemavharuvhu makuru kuti zvive nyore kudzora uye otomatiki mashandiro (zvinosanganisira Electric and Pneumatic Actuators)
Vharuvhu yemapuruguru inoshanda nekutenderedza dhisiki (kana vane) mukati mepombi kudzora kuyerera kwemvura. Dhisiki iyi yakaiswa padanda rinopinda nemumuviri wevharuvhu, uye kutenderedza danda kunotenderedza dhisiki kungava kuvhura kana kuvhara vharuvhu. Sezvo shaft ichitenderera, dhisiki inotenderera panzvimbo yakavhurika kana yakavhurika zvishoma, zvichiita kuti mvura ifambe zvakasununguka. Panzvimbo yakavharwa, Shaft inotenderedza dhisiki kudzivirira kuyerera kwemvura zvachose uye kuvhara vharuvhu.
Mavharuvhu emashavishavi ari kumativi maviri here?
Nzira dzinoshandisa nzira mbiri dzinogona kudzora kuyerera kwemvura munzira mbiri, Sezvatakataura, mashandiro emavharuvhu anogona kusvika pazvinodiwa. Saka mavharuvhu ebhatafurayi akabatana ari maviri, Kune zvakanakira zvakawanda kushandisa vharuvhu rebhatafurayi rakabatana.
1 Inodhura zvishoma kupfuura mamwe marudzi emavharuvhu nekuda kwekugadzirwa kwayo kuri nyore uye zvinhu zvishoma zvinodiwa pakuvaka. Kuchengetedza mari kunonyanya kuwanikwa mumavharuvhu makuru.
2 Zviri nyore kushandisa, kuisa nekugadzirisa, vharuvhu yemabhurugwa iri nyore kuita kuti zvive nyore uye nekukurumidza kuisa, inogona kuderedza mari yevashandi, dhizaini iri nyore, isingadhuri ine zvikamu zvishoma zvinofamba, uye nekudaro nzvimbo shoma dzekusakara, inoderedza zvakanyanya zvinodiwa pakugadzirisa.
3 Dhizaini yakareruka uye diki uye diki diki yevharuvhu yeshavishavi yakakombama, Inogonesa kuiswa uye kushandiswa munzvimbo dzisina nzvimbo yakawanda, Inoda nzvimbo shoma kana tichienzanisa nedzimwe mhando dzevharuvhu, dzakadai sevharuvhu dzegedhi kana dzeglobe, uye kuomarara kwadzo kunoita kuti kuiswa nekushanda zvive nyore, kunyanya mumasisitimu akazara nevanhu.
4 Inoshanda nekukurumidza, dhizaini yekutenderera yekona yekurudyi (90-degree) inopa kuvhura nekuvharira nekukurumidza. Iyi ficha inokosha mumashandisirwo apo mhinduro yekukurumidzira inokosha, senge mumasisitimu ekudzima emergency kana maitiro ane zvinodiwa zvekudzora zvakanyatsonaka. Kugona kuvhura nekuvharira nekukurumidza kunowedzera kupindura kwesisitimu, zvichiita kuti mavharuvhu emabhatani akabatana anyatsokodzera kudzora kuyerera kwemvura uye kudzora kwekudzima/kudzima mumasisitimu anoda nguva yakawanda yekupindura.
Chekupedzisira, vharuvhu remashavishavi rine nzira mbiri dzekuvhara divi rinoenderana nechinhu ichi rinokonzerwa nechimiro charo chekuvhara divi pakati pechigaro chevharuvhu nedhisiki remashavishavi, zvichiita kuti rigare richivharwa pasinei nekwakatenderedzwa nemvura. Dhizaini iyi inowedzera kuvimbika kwevharuvhu muhurongwa hwekudzora mvura munzira mbiri.
