Butterfly mavharuvhu anoshandiswa zvakanyanya mukugovera mvura, kurapwa kwemvura yetsvina, uye kurapwa kwemakemikari.Nekuti vane dhizaini iri nyore, shandisa zviwanikwa zvakanaka, zvidiki, uye zvakachipa.
Kuiswa kwakakodzera kwevhavha kunovimbisa kushanda kwakakwana uye hupenyu hurefu.Usati waisa butterfly valve, nzira yekuisa inofanira kunzwisiswa.Panguva yekuisa, iwe mudikani unofanirawo kutevera kuchengetedzwa kwekuchengetedza.
1. Nzira yekuisa sei butterfly valve pane pombi?
a)Zvishandiso zvinodiwa
Kuisa shavishavi vharuvhu kunoda maturusi akasiyana siyana kubatsira.
-Wrenches inosimbisa mabhaudhi.
-Torque wrenches tarisa kana kuiswa kuri mukati meiyo torque renji.
-Masikirivha anochengetedza zvikamu zvidiki.
-Vanocheka pombi vanogadzira nzvimbo dzekuisa shavishavi valve.
-Magirovhosi ekuchengetedza uye magirazi anodzivirira njodzi dzinogona kuitika.
-Level uye tambo yekuyeresa: Ita shuwa kuti shavishavi valve yakaiswa munzira kwayo.
b)Zvinhu zvinodiwa
-Zvinhu zvakananga zvinodiwa pakuiswa.
-Magetsi anonamira zvakanaka vharuvhu ye butterfly uye flange.
-Mabhaudhi uye nzungu anochengetedza vharuvhu ye butterfly kune pombi.
-Kuchenesa zvinhu kunobvisa marara kubva pombi uye mavharuvhu anogadzirwa panguva yekuiswa.
2. Kugadzirira Matanho
Kuongorora Butterfly Valve
-Kuongorora shavishavi vharafu isati yaiswa inhanho yakakosha.Mugadziri anotarisa vharafu yega yega yega isati yatumirwa.Zvisinei, nyaya dzinogona kumuka.
-Ongorora butterfly valve kune chero kukuvara kunooneka kana kuremara.
-Iva nechokwadi chekuti valve disc inotenderera zvakasununguka uye haina kunamatira.
-Ona kuti chigaro chevharuvhu chakamira.
-Tarisa kuti saizi yevharuvhu uye kudzvanywa zvinoenderana nepipeline's specs.
Gadzirira iyo Pipeline System
Zvakangokosha sekuongorora vharuvhu yeshavishavi kuongorora pombi.
-Chenesa pombi kubvisa ngura, marara uye zvinosvibisa.
-Tarisa kurongeka kwekubatanidza pombi flanges.
-Iva nechokwadi chekuti flanges dzakatsetseka uye dzakapfava pasina maburrs.
-Chengetedza kuti pombi inogona kutsigira huremu hwevhavhavhavhavha, kunyanya kune mavharuvhu makuru.Kana zvisina kudaro, shandisa bracket yakakosha.
3. Installation Process
a) Kuisa Butterfly Valve
Isa shavishavi vharafu zvakanaka mupombi.
Ivhavha disc yakavhurika zvishoma kudzivirira kuikuvadza kana chigaro kana uchidzvanya.Kana zvichidikanwa, shandisa flange yakakosha yakagadzirirwa mavharuvhu emhando ye butterfly.Ivhavha disc yakavhurika zvishoma kudzivirira kukuvadza dhisiki yevhavha kana chigaro chevharuvhu paunenge uchidzvanya chigaro chevharuvhu.
Tarisa pakatarisana
Ona kuti vharuvhu yeshavishavi yakaiswa mugwara chairo.
Centerline butterfly mavharuvhu anowanzo mativi maviri e butterfly mavharuvhu.Eccentric butterfly mavharuvhu haawanzo unidirectional kunze kwekunge zvichidikanwa.Mafambiro epakati anofanira kuenderana nemuseve uri pamutumbi wevharuvhu, kuitira kuti ive nechokwadi chekuvharisa kwechigaro chevharuvhu.
Kugadzirisa vharafu ye butterfly
Isa mabhaudhi kuburikidza nemakomba eflange evharuvhu yeshavishavi uye pombi.Ita shuwa kuti vharuvhu yeshavishavi yakapfava nepombi.Zvadaro, zvisimbise zvakaenzana.
Kusimbisa mabhaudhi mune nyeredzi kana nyeredzi (kureva, diagonal) nzira inogona kugovera zvakaenzana kudzvanywa.
Shandisa torque wrench kusvika kune yakatsanangurwa torque yebhoti yega yega.
Dzivisa overtightening, zvikasadaro zvinokuvadza valve kana flange.
Batanidza iyo actuator actuator yekubatsira mudziyo
Batanidza magetsi kune musoro wemagetsi.Zvakare, batanidza iyo mhepo sosi kumusoro wepneumatic.
Ongorora: Iyo actuator pachayo (mubato, giya rehonye, musoro wemagetsi, musoro wepneumatic) yakagadziridzwa uye yakagadziriswa yevhavhavhavhavha isati yatumirwa.
Kuongorora kwekupedzisira
-Tarisa kana butterfly valve seal uye pipeline ine chero zviratidzo zvekukanganisa kana kukuvara.
-Chengetedza kuti vharuvhu iri kufamba zvakanaka nekuvhura nekuvhara vharuvhu kakawanda.Kunyangwe iyo valve disc inogona kutenderera zvakasununguka pasina chero chipingamupinyi kana kupikisa zvakanyanya.
-Tarisa ese mapoinzi ekubatanidza kune inodonha.Iwe unogona kuita bvunzo yekuvuza nekudzvanya pombi yese.
-Gadzira chero zvigadziriso zvinodikanwa kuti uve nechokwadi chekushanda kwakakwana.
Kugadzirisa Matambudziko Anowanikwa
Butterfly valve haivhurike kana kuvhara zvakanaka: Tarisa uone zvinhu zviri kuvhara pombi.Zvakare, tarisa iyo actuator's power voltage uye air pressure.
Kudonhedza pakubatanidza: Tarisa kana pombi yeflange yepasi haina kuenzana.Zvakare, tarisa kana mabhaudhi akasungwa zvisina kuenzana kana kusunungurwa.
Kuiswa kwakakodzera uye kugadzirisa kunovimbisa kuti butterfly valve inoshanda zvakanaka mumhando dzakasiyana-siyana.Kuiswa kwevharuvhu yeshavishavi kunosanganisira matanho akakosha.Kuchenesa kusati kwaiswa, kurongeka kwakakodzera, kugadzirisa uye kuongorora kwekupedzisira kunovimbisa kushanda kwakakwana.Nyatsodzidza uye tevera matanho aya usati watanga kugadzwa.Kuita izvi kunogona kudzivirira matambudziko uye njodzi.
