Plastiki bhora mavharuvhu, sezvikamu zvakakosha zvekutonga mumapipeline masisitimu, anoshandiswa zvakanyanya munzvimbo dzakasiyana-siyana dzakadai sekurapa kwemvura, engineering yemakemikari, chikafu nemishonga. Sarudzo chaiyo yemodhi inoda kutariswa kwezvinhu zvakasiyana-siyana senge zvinhu, nzira yekubatanidza, chiyero chekumanikidza, tembiricha, nezvimwewo. Gwaro rino richasuma zvine hungwaru mapoinzi akakosha ekusarudza.epurasitiki bhora mavharuvhu, zvichikubatsira kuita sarudzo ine musoro.
Basic classification uye zviyero zvepurasitiki bhora mavharuvhu
1. Main classification nzira
Plastiki bhora mavharuvhu anogona kupatsanurwa maererano akasiyana zviyero:
(a) Nenzira yekubatanidza:
Flangeepurasitiki bhora vharafu: yakakodzera kune yakakura-diameter pipeline systems
Threaded epurasitiki bhora vharafu: inowanzoshandiswa diki-dhayamita mapaipi
Socket plastic ball valve: nyore kuisa nekukurumidza
Kaviri inotyairwa epurasitiki bhora vharafu: nyore disassemble uye kuchengetedza
(b) Nekutyaira modhi:
Manual bhora vharafu: ehupfumi uye inoshanda
Pneumatic bhora vharafu: otomatiki kudzora
Electric ball valve: kunyatsogadzirisa
(c) Nezvinyorwa:
UPVC bhora vharafu: yakakodzera kurapwa kwemvura
PP bhora vharafu: Chikafu neindasitiri yemishonga
PVDF bhora vharafu: Yakasimba corrosive medium
CPVC bhora vharafu: High tembiricha nharaunda
2. Mitemo yenyika uye tsanangudzo
Mitemo mikuru yeepurasitiki bhora mavharuvhumuChina ndeaya anotevera:
GB/T 18742.2-2002: Mavharuvhu ebhora epurasitiki akakodzera DN15~DN400, akatemerwa kudzvanywa PN1.6~PN16
GB/T 37842-2019 "Thermoplastic Ball Valves": Inokodzera thermoplastic bhora mavharuvhu kubva kuDN8 kusvika kuDN150 uye PN0.6 kusvika PN2.5
3. Kusarudzwa kwezvinhu zvekuisa chisimbiso
EPDM ternary ethylene propylene rubber: asidhi uye alkali inopikisa, tembiricha yakasiyana -10 ℃~+60 ℃
FKM fluororubber: solvent resistant, tembiricha yakasiyana -20 ℃~+95 ℃
PTFE polytetrafluoroethylene: inopesana nekuora kwakasimba, tembiricha yemhando -40 ℃ kusvika +140 ℃
