1. Nominal pressure (PN)
Nominal pressure yebutterfly valveireferensi kukosha kwakabatana nekumanikidza kuramba kugona kwepipeline system zvikamu.Inoreva dhizaini yakapihwa kudzvanywa inoenderana nesimba remakanika rezvikamu zvepombi.
Kudzvanywa kwezita kwevharuvhu yeshavishavi ndiko kusimba kwekudzivirira kwechigadzirwa (anotevera mavharuvhu) patembiricha yepasi.Zvinhu zvakasiyana-siyana zvine tembiricha dzakasiyana dzepasi uye kusimba kwesimba.
Kumanikidzwa kwezita, kunomiririrwa nechiratidzo PN (MPa).PN chiziviso chemusanganiswa wemabhii nenhamba dzinoshandiswa kureva zvine chekuita nemakanika zvivakwa uye dimensional hunhu hwepiping system zvikamu.
Kana iyo yekumanikidza yezita iri 1.0MPa, rekodha sePN10.Pasimbi yakakandwa nemhangura tembiricha yereferensi i120°C: pasimbi i200°C uye pasimbi yealloy i250°C.
2. Kumanikidzwa kwebasa (Pt)
Kushanda pressure yebutterfly valveinoreva kudzvinyirira kwakanyanya kunotsanangurwa zvichibva pane yekupedzisira tembiricha yekushanda kwemwero wega wega wepombi yekufambisa yepakati kuitira kushanda kwakachengeteka kwepombi system.Kungotaura, kudzvanywa kwekushanda ndiyo yakanyanya kumanikidza iyo system inogona kutsungirira panguva yekushanda kwakajairika.
3. Dhizaini kudzvanywa (Pe)
Dhizaini yedhizaini yevharuvhu (shavishavi) zvinoreva kuwanda kwepakarepo kunoitwa nepressure pombi system pamadziro emukati mevharuvhu.Iyo dhizaini yedhizaini pamwe chete neyakafanana dhizaini tembiricha inoshandiswa seyakagadziriswa dhizaini mamiriro, uye kukosha kwayo hakuzove kwakaderera pane kushanda kumanikidza.Kazhinji, iyo yakanyanya kudzvanywa iyo system inogona kutakura inosarudzwa panguva yekugadzira maverengero sedhizaini yekumanikidza.
4. Test pressure (PS)
Pamavharuvhu akaiswa, The test pressure ye butterfly valve inoreva dzvinyiriro iyo vharuvhu inofanira kusvika pakuita simba rekumanikidza uye kuyedza kusimba kwemhepo.
5. Hukama pakati petsanangudzo ina idzi
Nominal pressure inoreva simba rekumanikidzira patembiricha yepasi, asi kazhinji, haishande patembiricha yepasi.Sezvo kutonhora kuchichinja, simba rekumanikidza revhavha rinoshandukawo.
Kune chigadzirwa chine imwe zita rekumanikidza, kushanda nesimba kwainogona kumira kunotarirwa nekushisa kwekushanda kwepakati.
Iyo yekumanikidza yezita uye inobvumirwa kushanda kumanikidza kwechigadzirwa chimwe chete kuchave kwakasiyana pane dzakasiyana tembiricha dzekushanda.Kubva pakuona kwekuchengetedza, kudzvanywa kwekuyedza kunofanirwa kunge kwakakura kupfuura kudzvanywa kwezita.
Muinjiniya, kuyedza kumanikidza> zita kudzvanywa> dhizaini yekumanikidza> kushanda kumanikidza.
Mumwe nomumwevharafu kusanganisirabutterfly valve, vharafu yegedhi uye cheki chevhavha kubva kuZFA valve inofanira kudzvinyirirwa kuongororwa isati yatumirwa, uye muedzo wekuedza wakakura kudarika kana wakaenzana nechiyero chekuedza.Kazhinji, kuedzwa kwemuviri wevharuvhu ndeye 1.5 nguva yekumanikidza kwezita, uye chisimbiso ndeye 1.1 nguva yekumanikidzwa kwezita (nguva yekuedzwa haisi pasi pe5 maminetsi).
