3. Mutengo
Mutengo weButterfly Valve
Butterfly mavharuvhu anowanzo kuchipa kupfuura mavharuvhu egedhi.Izvi zvinodaro nekuti mavharuvhu eshavishavi ane hurefu hwechimiro, anoda zvinhu zvishoma, uye ane maitiro ari nyore ekugadzira.Mukuwedzera, mavharuvhu e butterfly akareruka, izvo zvinoderedzawo mari yekufambisa nekuisa.Kukosha kwemutengo wemavharuvhu eshavishavi kunonyanya kuoneka mumapaipi makuru-dhayamita.
Mutengo weGedhi Valve
Mari yekugadzira yemavharuvhu emagedhi inowanzokwira, kunyanya kune yakakura-dhayamita kana yakakwirira-kumanikidza application.Chimiro chemavhavha emagedhi chakaoma, uye machining akarurama emagedhi emagedhi uye zvigaro zvevhavha zvakakwirira, izvo zvinoda mamwe maitiro uye nguva panguva yekugadzira.Mukuwedzera, mavhavha emagedhi anorema, izvo zvinowedzera mari yekufambisa uye kuiswa.
Sezvinoonekwa kubva padhirowa iri pamusoro, kune imwecheteyo DN100, vharafu yegedhi yakakura kwazvo kupfuura vhavhavhavhavha.
4. Kugara kwenguva refu
Kugara kweButterfly Valve
Kusimba kwemavharuvhu eshavishavi kunoenderana nechigaro chevharuvhu uye zvinhu zvemuviri wevharuvhu.Kunyanya, zvisimbiso zvekuvhara zvinyoro-yakavharwa mavhavhavhavha evhavha anowanzogadzirwa nerabha, PTFE kana zvimwe zvinhu zvinoshanduka, izvo zvinogona kupfeka kana kukwegura panguva yekushandiswa kwenguva refu.Zvechokwadi, zvigadzirwa zvekuisa chisimbiso zvemavhavhavhavha evhavha yakaoma-yakavharidzirwa yakagadzirwa nepamusoro-soro yekugadzira zvinhu kana zvisimbiso zvesimbi, saka kusimba kwakagadziridzwa zvakanyanya.
Kazhinji, mavharuvhu e butterfly ane durability yakanaka mu low-pressure and medium-pressure systems, asi kuiswa chisimbiso kunogona kuderedzwa munzvimbo dzepamusoro-soro uye dzepamusoro-tembiricha.
Zvakakoshawo kutaura kuti mavharuvhu eshavishavi anogona kutsaura svikiro nekuputira muviri wevharuvhu nechigaro chevharuvhu kudzivirira muviri wevharuvhu kuti urege kuita ngura.Panguva imwecheteyo, ndiro yevhavha inogona kuvharwa zvakakwana nerabha uye yakanyatsogadziriswa nefluorine, iyo inovandudza zvakanyanya kusimba kwayo kune zvinoparadza media.
Kugara kwemavhavha emagedhi
Iyo elastic chigaro chisimbiso dhizaini yemagedhi mavharuvhu anotarisana nedambudziko rakafanana nevhavhavhavhavha, ndiko kuti, kupfeka uye kuchembera panguva yekushandiswa.Zvisinei, mavharuvhu emagedhi akaoma-akavharidzirwa anoita zvakanaka mumhepo yepamusoro-soro uye yepamusoro-yekushisa.Nekuti iyo simbi-ku-metal yekuisa chisimbiso pamusoro pevhavha yegedhi ine yakakwira kupfeka kusagadzikana uye kushora kushora, hupenyu hwayo hwesevhisi hunowanzoreba.
Zvisinei, gedhi revhavha yegedhi rinonamirwa nyore nyore nekusachena mukati, izvo zvingakanganisawo kusimba kwayo.
Mukuwedzera, chitarisiko chayo uye chimiro chinotarisa kuti zvakaoma kuita chigadziko chakazara, saka kune imwechete yakasvibiswa yepakati, ingave yakagadzirwa nesimbi yose kana yakazara yakazara, mutengo wayo wakakwirira zvikuru kupfuura wevhavha yegedhi.

Kuyerera kwegedhi valve
Ivhavha yegedhi yakagadzirwa kuti ive yakanyatsokodzera kuvhura kuzere kana kuzara kwekuvhara mabasa, asi kwete yekutonga kuyerera.Mune chikamu chakavhurika chikamu, gedhi richakonzera kusagadzikana uye kudengenyeka kwemvura, izvo zviri nyore kukuvadza chigaro chevharuvhu uye gedhi.
6. Kuiswa
Kuiswa kwevhavhavhavhavha
Kuiswa kwevharuvhu ye butterfly kuri nyore.Iyo yakareruka muhuremu, saka haidi kutsigirwa zvakanyanya panguva yekuiswa;ine compact chimiro, saka inonyanya kukodzera kune zviitiko zvine nzvimbo shoma.
Iyo butterfly valve inogona kuiswa pamapombi mune chero nzira (yakatwasuka kana yakatwasuka), uye hapana chakasimba chinodiwa chekuyerera kutungamira mupombi.Izvo zvinofanirwa kucherechedzwa kuti mune yakakwirira-kudzvanywa kana yakakura-dhayamita maapplication, butterfly ndiro inofanirwa kunge iri munzvimbo yakazaruka yakazara panguva yekuiswa kuti isakuvara kune chisimbiso.
Kuiswa kwemavhavha emagedhi
Kuiswa kwemavharuvhu emagedhi kunonyanya kuoma, kunyanya makuru-diameter uye akaoma-akavharwa mavhavha emagedhi.Pamusana pehuremu hukuru hwemavhavha emagedhi, humwe hutsigiro uye matanho ekugadzirisa anodiwa panguva yekuisa kuti ave nechokwadi chekugadzikana kwevhavha uye kuchengetedzwa kwemugadziri.
Mavharuvhu egedhi anowanzo kuisirwa pamapombi akachinjika, uye mafambiro emvura anoda kutariswa kuti ave nechokwadi chekuisa kwacho.Mukuwedzera, kuvhura uye kuvhara kwevhavha yegedhi yakareba, kunyanya kukwira-stem gedhi mavharuvhu, uye nzvimbo yakakwana inoda kuchengetwa kuti ishandise handwheel.
7. Kuchengetedza uye kuchengetedza
Kugadziriswa kwemavharuvhu e butterfly
Butterfly valves ine zvikamu zvishoma uye zviri nyore kuparadzanisa uye kuungana, saka zviri nyore kuchengetedza.Mukugadzirisa kwezuva nezuva, kuchembera uye kupera kweplate yevharuvhu uye chigaro chevharuvhu zvinotariswa zvakanyanya.Kana mhete yekuisa chisimbiso ichionekwa kuti yakanyanyisa kupfeka, inoda kuchinjwa nenguva.Naizvozvo, isu tinokurudzira kuti vatengi vatenge inotsiviwa nyoro-kumashure butterfly mavharuvhu.Kana iyo yepamusoro flatness uye kupera kweplate yevhavha yakaoma kuwana yakanaka yekuisa chisimbiso, inodawo kutsiviwa.
Mukuwedzera, pane lubrication yevhavha stem.Kuzora kwakanaka kunobatsira kuchinjika uye kusimba kwekushanda kwevharuvhu yeshavishavi.
Kugadziriswa kwemavhavha emagedhi
Mavhavha emagedhi ane zvikamu zvakawanda uye zvakaoma kuparadzanisa uye kuungana, kunyanya mumagadzirirwo makuru epombi, uko basa rekuchengetedza rakakura.Panguva yekugadzirisa, kunyanya kunofanira kubhadharwa kuti gedhi rinosimudzwa uye rakaderedzwa zvakanaka uye kana pane zvinhu zvekunze mu groove yemuviri wevhavha.
Kana iyo yekubata kumeso kwechigaro chevhavha uye gedhi rakakweshwa kana kupfekwa, rinoda kukwenenzverwa kana kutsiviwa.Ehezve, iyo lubrication yevhavha stem inodiwa zvakare.
Kunyanya kukoshesa kunofanira kubhadharwa kune kuchengetedzwa kwekutakura kupfuura butterfly valve.Kurongedzerwa kwevharuvhu yegedhi kunoshandiswa kuvhara mukaha pakati pehunde yevharuvhu nemuviri wevharuvhu kudzivirira yepakati kubva pakubuda.Kuchembera uye kupfeka kwekurongedza ndiwo matambudziko akajairika emavhavha emagedhi.Panguva yekugadzirisa, zvinodikanwa kugara uchitarisa kusimba kwekurongedza uye kugadzirisa kana kuitsiva kana zvichidikanwa.
8. Mhedziso
Muchidimbu, butterfly mavharuvhu uye gedhi mavharuvhu ane zvawo zvakanakira uye zvisingabatsiri maererano nekuita, mutengo, kusimba, kuyerera uye kuisirwa:
1. Nheyo: Mavharuvhu eButterfly ane kukurumidza kuvhura uye kuvhara kumhanya uye akakodzera kukurumidza kuvhura nekuvhara zviitiko;mavharuvhu emagedhi ane nguva refu yekuvhura nekuvhara.
2. Kuumbwa: Butterfly mavharuvhu ane chimiro chakareruka uye mavharuvhu egedhi ane maitiro akaoma.
3. Mutengo: Butterfly mavharuvhu ane mutengo wakaderera, kunyanya kune yakakura-dhayamita application;mavharuvhu egedhi ane mutengo wakakwira, kunyanya kudzvinyirirwa kwakanyanya kana zvakakosha zvinhu zvinodiwa.
4. Durability: Butterfly mavharuvhu ane zviri nani kusimba mune yakaderera-kudzvinyirira uye yepakati-kudzvinyirira masisitimu;mavharuvhu emagedhi anoita zvakanaka munzvimbo dzekudzvanya uye nepamusoro-soro, asi kuvhurika nekuvharika kazhinji kunogona kukanganisa hupenyu hwavo.
5. Flow regulation: Butterfly mavharuvhu akakodzera rough flow control;mavharuvhu emagedhi anonyanya kukodzera kumabasa akazaruka kana akazara akavharwa.
6. Kuiswa: Butterfly mavharuvhu ari nyore kuisa uye anoshanda kune ese ari maviri akatwasuka uye akatwasuka mapaipi;mavharuvhu emagedhi akaoma kuisa uye akakodzera kugadzika pombi yekuisa.
.Pamusoro peizvi, vheji yegedhi inodawo kuchengetedza kurongedza.
Mumashandisirwo anoshanda, kusarudzwa kwemavharuvhu e butterfly kana mavharuvhu egedhi kunofanirwa kutariswa zvakakwana zvichienderana nemamiriro ekushanda uye zvinodiwa kuti ive nechokwadi chekushanda kwakanaka uye hupfumi.
