- ARAN inogadzira Trunnion Bhora Mavharuvhu inowanikwa mune yakakura dhizaini, zvishandiso, saizi uye makirasi ekumanikidza uye ari kuenderana zvizere nemitemo yekugadzira yepasirese ANSI, ASME B16.34, API 6D, ISO17292, GOST, DIN/EN zvakatemwa nezvimwe.
- Trunnion ball valve ine yakakura chiyero chekugadzira chiyero Kirasi 150 ~ Kirasi 2500, PN16 ~ PN420, zvinhu zvakasiyana-siyana zvinoshandiswa kutakura mvura / utsi / mafuta uye gasi maindasitiri, inogona kunge yakaderera tembiricha uye yakanyanya kudzvinyirira mamiriro ekushandisa, yakakodzera zvigadzirwa senge, nitric acid, acetic acid, oxidizing media, urea, nezvimwe.
- Iyo trunnion bhora mavharuvhu anoshandiswa zvakanyanya mukunatsa peturu, mapaipi marefu, indasitiri yemakemikari, kugadzira mapepa, mishonga, kuchengetedza mvura, simba remagetsi, manejimendi ekanzuru, simbi nemimwe minda nezvimwe.
Chii chinonzi Trunnion ball valve definition?
- The trunnion ball valve is a quarter-turn valve uye trunnion design zvinoreva kuti kuungana kwebhora kunotsigirwa netrunnion yerutsigiro yakaderera uye nedzinde repamusoro mukamuri yebhora.Iyi dhizaini inonzi trunnion mounted ball valve kana trunnion ball valve.
- Iyo trunnion bhora vharafu inowanzo shandiswa kune yakakura saizi uye yakakwirira yekumanikidza bhora bhora mashandiro, pamwe nekudzikisa torque yevharuvhu kuti ishande nyore.
- Iyo trunnion-yakamisikidzwa hunde inotora kusundirwa kubva mumutsara kudzvanywa, ichidzivirira kukweshana kwakanyanya pakati pebhora nezvigaro, saka iyo valve inoshanda torque inoramba yakaderera pane yakazara yakayerwa kushanda kumanikidza.
- Ko trunnion bhora vharafu chigaro chisimbiso?
- Kuisa chisimbiso kunowanikwa nechitubu chakaremerwa piston mhando zvigaro izvo zvinovhara kuyerera kana mutsetse wekumanikidza unobata pachigaro chekumusoro.Kusununguka otomatiki kwegomba pamusoro pekumanikidza kunovimbiswa nekuda kweiyo trunnion dhizaini kana paine zvigaro zvekuzvisunungura.Bhora rinoshandiswa nesimbi yakavharwa iyo inosungirirwa mushandisi.Mavharuvhu ebhora anoitirwa kuti ashandiswe kunge ari on/off flow control madivayiri uye haafanirwe kushandiswa throttle fluid kuyerera.Mavharuvhu anofanirwa kugara akazaruka kana kuvharwa.
- Trunnion ball valve zvigaro dhizaini zvine zvakakosha dhizaini maficha kune akasiyana maapplication zvinodiwa:
- ● SELF RELIEVING SEATS / SINGLE RELIEF SEATS(SPE) uye DOUBLE PISTON EFFECT SEATS (DEP)
- ● DBB uye DIB zvigaro zvekugadzira
- Iyo trunnion bhora revhavha bhora rakagadziriswa asi zvigaro zvinochinjika.Chigaro chine SELF RELIEVING SEATS / SINGLE RELIEF SEATS (SPE) uye DOUBLE PISTON EFFECT SEATS (DEP) dhizaini.Iyo SPE dhizaini ndiyo imwe nzira uni-directional chisimbiso uye DEP iri bi-direction chisimbiso, ne API 6D/ISO 14313 tsanangura.
- ARAN inoshandisa trunnion bhora vharafu yakagadzirirwa zvigaro zvigaro zvekuyamura SPE-SPE uye kaviri block uye kubuda ropa DBB seyakajairwa chigadzirwa.Asi mamwe marudzi zvigaro dhizaini inowanikwawo pane chaiyo chikumbiro.
- Imwe Piston Effect Seat Dhizaini maficha
- Zvigaro zvemavharuvhu ebhora zvinotsikirirwa pabhora nenzira yekuremerwa kwechirimo.
- Sezvo kumanikidza kwemuviri wemukati kunowedzera kupfuura mutoro wechirimo, zvigaro zvinosundirwa kumashure uye kudzvanywa kunoburitswa mumutsara.Izvi zvinodaidzwa kuti single-piston effect (kudzvanywa mumhango yemuviri ndiyo chete inoita parameter) .Cavity relief kudivi rezasi, kana zvese zvigaro zvevharuvhu zvebhora zviri zve single-piston effect design.Chigaro chega chega chiri kuzvisunungura wega mhango yemuviri pamusoro pekumanikidza kumutsara.

- Kaviri Piston Effect Seat Dhizaini maficha
- Mukugadzirwa kwechigaro ichi, kudzvanywa kwepakati, pamwe nekumanikidzwa kwegomba remuviri, zvinogadzira mhedzisiro inosundira mhete dzechigaro kubhora.Izvi zvinonzi double piston effect (kumanikidza mupombi & kuti mumuviri mhango zvose zviri acting parameters) .Ball Mavharuvhu ane dhizaini iyi anoda mhango pressure yekuyamura mudziyo kuderedza mhango yemuviri pressure.

- Trunnion Bhora vharafu DBB uye DIB zvigaro dhizaini tsananguro
- ● DBB bhora vharafu (double block uye bleed bhora vharafu)
- DBB bhora mavharuvhu kuita vharafu imwe chete ine zvigaro zviviri zvisina unidirectional.Iyi kaviri block uye yekubuda ropa valve inovhara kupesana nekumanikidza kubva kumativi ese evhavha.Iri vharuvhu haipe kuparadzaniswa kwakapetwa kaviri kana divi rimwe chete riri pasi pekumanikidzwa.
- DBB bhora vharafu inogona kutariswa sevharuvhu ine maviri single piston effect (SPE) zvigaro.
- ● DIB bhora vharafu (kuzviparadzanisa kaviri uye kubuda ropa bhora vharafu)
- DIB bhora vharafu ivharuvhu imwe chete ine zvigaro zvebidirectional.Iyi kaviri yekuzviparadzanisa-uye-kubuda ropa valve inopa chisimbiso chekuwedzera chinopesana nekumanikidza kubva kune rumwe rutivi chete.Iyi DIB ficha inogona kupihwa mune imwe nzira kana mumativi ese.Ivhavha inopa kuparadzaniswa kaviri kubva pakumanikidzwa kumativi ose maviri evhavha asi haigoni kusunungura muviri wevhavha yekumanikidza kupfuura zvigaro.
- Iyo DIB ficha inogona kupihwa mune imwe nzira kana mativi ese.
- Ivhavha ine mbiri mbiri piston effect (DPE) zvigaro zvine kaviri kuzviparadzanisa uye kubuda ropa (DIB-1) dhizaini.Ivhavha ine chigaro chimwe cheSPE uye imwe chigaro cheDPE idhizaini yeDIB-2.A DIB-2 vharuvhu ichava neanofarira yekuisa nzira.
