Hutsanana chinhu chinonyanya kukosha mukugadzira chikafu nechinwiwa. Butterfly mavharuvhu ane hutsanana dhizaini nenzvimbo dzakakwenenzverwa anogona kushandiswa kuchengetedza hutsanana nekudzivirira kusvibiswa pakubata zvinwiwa zvakaita sejusi, zvigadzirwa zvemukaka, uye zvinwiwa. Zvese zviri zviviri wras-certified rubber uye chikafu-giredhi simbi isina tsvina zvinogona kusangana nechiyero ichi.
1.3.6. Marine uye Shipbuilding
Aluminium bronze butterfly mavharuvhu akagadzirirwa marine application kudzora ballast masisitimu, mvura inotonhorera, uye mitsara yemafuta. Zvinhu zvisingadziviriri zvemavharuvhu eshavishavi zvinoita kuti zvive zvakanakira kushandiswa munzvimbo dzakaoma dzemugungwa.
1.3.7. Power Plants
Muzvidyarwa zvemagetsi, butterfly mavharuvhu anoshandiswa mukutonhodza masisitimu, mitsara yemhepo, uye flue gasi desulfurization masisitimu. Ivo vanokwanisa kubata high pressure uye high tembiricha mvura.
1.3.8. Wastewater Treatment Plants
Butterfly mavharuvhu akakosha pakugadzirisa sludge, aeration, uye kuyerera kwemvura munzvimbo dzekuchenesa mvura.
1.3.9. Pulp uye Pepa Indasitiri
Iyo pulp uye mapepa indasitiri inobatsirwa kubva kune butterfly mavharuvhu mumiitiro yakadai sekubikira pulp, bleaching, uye makemikari kudzoreredza. Kuramba kwavo kune abrasive pulp uye makemikari kunowedzera kushanda zvakanaka uye hupenyu hwebasa.
2. Kuvakwa kweButterfly Valve
2.1. Zvikamu zveButterfly Valve
Zvinhu zvakakosha zvinosanganisira:
Valve body: Imba inogara zvimwe zvikamu zvemukati.
Disiki revhavha: Inovhura uye inovhara nekutenderera 90 madhigirii.
Stem: Inobatanidza disc kune actuator.
Seat: Inopa chisimbiso kudzivirira kuvuza.
2.2. Mhando dze butterfly mavharuvhu zvichienderana nechimiro
Wafer type: Yakaiswa pakati pemafurange epombi uye yakagadziriswa nemabhaudhi.
Lug type: Inoshandisa ma threaded ekuisa pakuisa.
Flange type: Iine maflange maviri uye inoiswa nepombi.
2.3. Zvishandiso zve butterfly valves
Muviri: Kanda simbi, simbi isina tsvina kana kabhoni simbi.

4. Kuiswa nekuchengetedza mavharuvhu e butterfly
4.1 Nzira yekuisa kwayo yemavharuvhu eshavishavi
Vhura iyobutterfly valvendiro pakona ye0-90 madhigirii.
Ita shuwa kuchengetedza zvakakwana clearance kubva kune zvimwe zvikamu.
Iva nechokwadi chokuti ndiro yevhavha haina kubata pombi flange.
Simbisa kurongeka uye kubviswa kwe disc kutenderera.
4.2. Kugadziriswa kwezuva nezuva kwemavharuvhu e butterfly
Tarisa kuti hapana kupera uye chinja kana zvichidiwa.
Zora zvikamu zvinofamba sezvinodiwa.
4.3. Common matambudziko ekugadzirisa matambudziko uye mhinduro
Leaks: Tarisa chigaro chakavimbika.
Yakanamirwa: Chenesa marara enzvimbo yechigaro uye chengetedza mafuta akakodzera.
5. Kuenzanisa nemamwe marudzi evhavha
5.1 Butterfly valve vs. bhora vharafu
Butterfly valve: Yakareruka uye yakawanda compact.
Bharuvha yebhora: Yakanyanya kukodzera kuyerera kwakazara, inogona kushandiswa se viscous uye fibrous fluid.
5.2. Butterfly valve vs. gedhi vharafu
