1.Centerline butterfly valveuye eccentric butterfly valve
Centerline butterfly valve uye eccentric butterfly valve ine zvayakanakira nezvayakaipira，Pakusarudza modhi, inofanirwa kutariswa zvizere pamwe chete nemutengo wayo.Kazhinji kutaura, iyo yepakati mutsara butterfly valve yakachipa pane eccentric butterfly valve.Mavharuvhu emashavishavi eCenterline anoshandiswa zvakanyanya mumavharuvhu eshavishavi renyika yangu madiki-dhayamita, uye mhedzisiro yacho yakanaka.Chisimbiso chayo chekuvhara chisimbiso ndeye rubber lining squeeze chisimbiso, kunyanya pedyo nevhavha shaft inonyanya kudzvinyirirwa, kuitira kuti hupenyu hwebasa hwevhavha hunokanganiswa, uye kuvhura uye kuvhara torque yevhavha yakakura zvikuru.Kuti kuderedze kukanganisa kwechinhu ichi, eccentric butterfly valve yakaonekwa.Iyo theoretical sealing state inzvimbo yekubatisa chisimbiso.Vazhinji vagadziri vakagadzira chikamu ichi.Iyo eccentric butterfly valve inotungamira mukubereka mvura, kunyanya matatu-dimensional eccentric butterfly valve.Reverse pressure inotakura simba haina simba.Nemhaka yokuti pombi network yakaita mhete, zvinodiwa kuti vharuvhu itakure kudzvinyirirwa kumativi ose maviri zvakafanana, saka ichi chinodiwa chinofanira kusimbiswa pakusarudza vharuvhu.
2.Vertical uye horizontal butterfly mavharuvhu
Mumavharuvhu eshavishavi epakati nepakati, pane musiyano pakati pemavharuvhu akatwasuka uye akachinjika.Kazhinji, vertical butterfly mavharuvhu akafukidzwa nevhu rakadzika, uye marara mumvura angangodaro akaputira kumativi e shaft uye anokanganisa kuvhura nekuvhara;iyo inochinja-chinja yekumhanyisa bhokisi reyakachinjika butterfly mavharuvhu riri padivi.Iyo vharafu zvakanaka inotora nzvimbo yakakura yendege munzira, iyo inokanganisa kurongeka kwemamwe mapaipi.Nokudaro, maererano nezvinetso zviri pamusoro apa, inofanira kunge yakajeka mukusarudza kwevhavha: mavharuvhu epakati-diameter butterfly anonyanya kumira, uye mavharuvhu makuru-diameter butterfly anofanira kutanga akaenzana kana mamiriro enzvimbo yendege achibvumirwa.Izvi hazvisi kungovandudza zvakanyanya mamiriro ekuyerera kwevhavha, asiwo zvinogadzirisa zvachose dambudziko rezvipembenene mumvura yakasungirirwa nevhavha shaft.
3.Soft chisimbiso uye chisimbiso chesimbi.
Mazhinji evhavhavhavhavha anoshandiswa muindasitiri yekugovera mvura ndeyemavharuvhu eshavishavi akapfava.Nekuda kwemamwe matambudziko mukushandiswa kweiyi nzira yekuisa chisimbiso, vagadziri vazhinji vakaunza mavharuvhu eshavishavi akavharwa nesimbi kutsiva mavharuvhu akavharwa nerabha.Patinosarudza zvisimbiso zvakapfava uye mavharuvhu esimbi esimbi, isu tichiri kufanira kufunga nezvekudhura-kubudirira kwezviviri.
①Matambudziko makuru ekunyorovesa sealing butterfly valve ari kushandiswa ndeaya: yakashata rabha mhando, nyore kuchembera, kureba kwekumanikidza deformation, uye extrusion kuparuka.Naizvozvo, vamwe vagadziri vanowanzo sarudza EPDM rabha uye nitrile rabha uye vanoshandisa yakasikwa rabha mune zvidiki.Izvo zvinorambidzwa zvachose kusanganisa recycled rabha kuti uvandudze kupfeka kuramba uye kuchembera kuramba kwemhete yekuisa chisimbiso.
②Isimbi-yakavharwa shavivhavhavha inogaro tora eccentric chimiro, kunyanya matatu-dimensional eccentric chimiro, nekuda kwekutetepa kwechisimbiso.Iyo simbi-yakavharwa butterfly valve yakatanga kushandiswa pamapaipi emhepo inotsikirira, uye mutengo unodhura.Chisimbiso chayo chekuisa chisimbiso hachisi nyore kukuvadzwa panguva yekushanda, asi kururama kwayo kwekugadzira kwakakwirira, uye kana ichinge ichidonha, zvakaoma kugadzirisa.
