kushanda musimboti
A butterfly valveimhando yevharuvhu inogadzirisa kuyerera kwepakati nekuvhura kana kuivhara nekudzoka nekudzoka zvinosvika 90 degrees. Pamusoro peiyo yakatwasuka dhizaini, saizi diki, huremu huremu, kuderera kwekushandisa kwezvinhu, kuiswa nyore, kuderera kwekutyaira torque, uye kukurumidza kushanda, iyobutterfly valveinoitawo zvakanaka maererano nekuyerera kwemutemo ukuwo uine yakanaka yekuvhara uye yekuisa chisimbiso hunhu. imwe yemhando dzinokurumidza dzevhavha. Kushandiswa kwebutterfly mavharuvhuzvakajairika.

Mashandisirwo ayo anoenderera mberi nekusiyana uye kuwedzera, uye ivo vari kuchinjika kune yakanyanya tembiricha, kudzvanywa kwepamusoro, dhayamita hombe, chisimbiso chepamusoro, hupenyu hurefu, hunhu hunoshamisa hwekugadzirisa, uye kuwanda-kushanda kwevharuvhu. Ikozvino ine mwero wepamusoro wekuvimbika uye mamwe maitiro ekuita.

Kushanda kwemavharuvhu eshavishavi kwave nani nekuda kwekushandiswa kwemakemikari anodzivirira erabha. Sezvo rabha rekugadzira riine hunhu hwekuramba kukoromoka, kukura kwakadzikama, kugadzikana kwakanaka, nyore kugadzira, uye mutengo wakaderera, rabha rekugadzira rine zvinhu zvakasiyana-siyana rinogona kusarudzwa maererano nezvinodiwa zvakasiyana-siyana zvekushandisa kugutsa mamiriro ekushanda evhavhavhavhavha.

Sezvo polytetrafluoroethylene (PTFE) ine simba rakasimba rekudzivirira kuparara, kushanda kwakadzikama, kupikisa kukwegura, kuderera kwehutano hwehutachiwana, kusununguka kwekuumbwa, uye kugadzikana kwehukuru, kushanda kwayo kwose kunogona kusimbiswa nekuzadza nekuwedzera zvinhu zvakakodzera kuti uwane simba rakanaka uye kukakavara. Synthetic rabha ine zvimwe zvinokanganisa, asi zvinhu zvekuvharisa vharuvhu yeshavishavi zvine mutsindo wakaderera unozvitenderedza. Kuti uvandudze mashandiro evhavhavhavhavhavha, yakakwira molecular polymer zvinhu, senge polytetrafluoroethylene, uye kuzadza kwavo kwakagadziridzwa zvinhu zvakashandiswa zvakanyanya. Ikozvino yakakwidziridzwa, uye vharuvhu yeshavishavi yakagadzirwa ine tembiricha yakakura uye kudzvanywa kwemhando, yakavimbika yekuisa chisimbiso kuita, uye hupenyu hurefu hunobatsira.

Metal-sealed butterfly mavharuvhu akafambira mberi zvakanyanya kuitira kuti azadzise zvikumbiro zvemaindasitiri senge tembiricha yepamusoro uye yakaderera, kukukurwa kwakasimba, uye hupenyu hwakareba. Metal-sealed butterfly mavharuvhu ave achishandiswa zvakanyanya muminda yemaindasitiri senge tembiricha yakakwira uye yakaderera, kukukurwa kwakasimba, uye hupenyu hurefu nekuda kwekushandiswa kwekupisa kwekushisa kwakanyanya, kushomeka kwekushisa, kusaita ngura kwakasimba, kusimba kwekukukurwa kwevhu, uye kusimba kwakanyanya. alloy zvinhu. Kuitira kufambisira mberi tekinoroji yevharuvhu yeshavishavi, dhayamita hombe (9-750mm), high pressure (42.0MPa), uye tembiricha yakakura (-196–606°C) mavharuvhu eshavishavi akatanga kusimuka.

Ivharuvhu yeshavishavi ine kakuramba kuyerera kana yanyatsovhurwa. Mavharuvhu e butterfly anowanzo shandiswa mundima yekutonga-dhayamita hombe nekuti anokwanisa kudzora kuyerera kwakapfava pakuvhurwa kuri pakati pe15° ne70°.

Ruzhinji rwemavharuvhu eshavishavi anogona kushandiswa nenhepfenyuro ine zvimedu zvakaturikwa zvakasimba sezvo ndiro yeshavishavi inofamba ichipukuta. Inogona zvakare kushandiswa kune granular uye powdery media, zvichienderana nekusimba kwechisimbiso.

Butterfly mavharuvhu anobatsira pakudzora kuyerera. Pakusarudza vharuvhu yeshavishavi, zvakakosha kuti utarise zvizere kukanganisa kwekurasikirwa kwekumanikidzwa kwepipeline system pamwe nekusimba kweplate yeshavishavi kuti rimire kumanikidza kwepakati pepipeline kana yakavharwa nekuda kwekurasikirwa kwekumanikidzwa kweshavishavi. vharafu mupombi yakakura, ingangoita katatu iyo yevhavha yegedhi. Kupisa kwekushanda kweiyo elastic chigaro zvinhu pakupisa kwakanyanya kunofanirwawo kuverengerwa.

The butterfly valve ine chimiro chipfupi uye yakaderera kureba. Inovhura uye inovhara nekukurumidza uye ine yakanaka fluid control properties. Kugadzira mavharuvhu makuru-dhayamita akanyatsokodzera dhizaini yemagadzirirwo evharuvhu. Nhanho inonyanya kukosha pakusarudza vharuvhu yeshavishavi iyo inoshanda nemazvo uye zvinobudirira kana ichishandiswa kudzora kuyerera ndeyekusarudza mhando yakakodzera uye yakatarwa.

Butterfly mavharuvhu anowanzo kurairwa kuti ashandiswe mukupuruzira, kudzora kudzora, uye madhaka media uko kupfupi kwechimiro kureba, kukurumidza kuvhura uye kuvhara kumhanya, uye yakaderera kuchekwa-kubvisa (kudiki kudzvinyirira musiyano) kunodiwa. Butterfly mavharuvhu anogona kushandiswa neabrasive media, yakaderedzwa-dhayamita chiteshi, yakaderera ruzha, cavitation uye vaporization, diki diki yekudonha kwemhepo, uye kaviri-nzvimbo kugadzirisa. Kugadziriswa kweThrottle kana uchishanda pasi pemamiriro asina kujairika, senge pakusunga chisimbiso, kupfeka kwakanyanya, tembiricha yakaderera zvakanyanya, zvichingodaro.
