Dakel so klase na butterfly valves, tan dakel so paraan na panagklasipika.
1. Klasipikasyon unong ed porma na istruktura
(1)konsentrikon balbula na kulibangbang; (2) single-excentric butterfly valve; (3) doble-eksentrikon balbula na kulibangbang; (4) taloran-eksentrikon balbula na kulibangbang
2. Klasipikasyon unong ed materyales ed tapew na seal
(1) Mabiskeg a balbula na kulibangbang
(2) Metal-type hard-sealed butterfly valve. Say sealing pair et tugyopen na metal ya malet ya materyal ya anggad metal ya malet ya materyal.
3. Klasipikasyon base ed selyadon porma
(1) Puersaan ya insara so balbula na kulibangbang.
(2) Pressure sealing butterfly valve. Say seal pressure et napapawala na elastic sealing element ed yurongan odino plato.
(3) Automatikon akasara ya balbula na kulibangbang. Say seal specific pressure et automatikon napapawala na medium pressure.
4. Klasipikasyon unong ed presyon na trabaho
(1) Say vacuum butterfly valve. Butterfly valve ya say presyon to et mas abeba nen say estandarten atmospera.
(2) Low-pressure butterfly valve. Butterfly valve ya walay nominal pressure ton PN≤1.6MPa.
(3) Medium-pressure butterfly valve. Say nominal pressure PN et say butterfly valve ya 2.5∽6.4MPa.
(4) High-pressure butterfly valve. Say nominal pressure PN et say butterfly valve ya 10.0∽80.OMPa.
(5) Ultra-high pressure butterfly valve. Butterfly valve ya walay nominal pressure ya PN <100MPa.
5. Klasipikasyon unong ed paraan na koneksion
(1)Wafer butterfly valve
(2) Flange butterfly valve
(3) Lug butterfly valve
(4) Welded butterfly valve
Say Concentric Butterfly valve et sakey a klase na balbula ya manlulukas tan mansara panamegley na pabilog a butterfly plate tan manlukas, mansara tan mangi-adjust ed fluid channel diad pangipawil na valve stem. Say butterfly plate na butterfly valve et akapuesto ed direksion na diametro na tubo. Diad cylindrical channel na butterfly valve body, say disc butterfly plate et onliliber ed axis, tan say rotation Angle et walad baetan na 0 tan 90. No say rotation et onsabi ed 90, say valve et sigpot lan lukas.
Saray manunan punto na panagpaalagey tan pangipaalagey
1) Say posisyon na pangipaalagey, katagey, direksion na pangiloob tan pangipaway et nepeg ya makatunongan ed saray kakaukolanen ed desinyo, tan say koneksion et nepeg ya malet tan malet.
2) Say panangawit na amin a klase na manual a balbula ya inyan ed tubo na thermal insulation et nepeg ya ag-onleksab.
3) Say balbula et kaukolan ya inspeksionen ed paway antis ya i-install, tan say nameplate na balbula et nepeg ya ontumbok ed saray probisyon na kaplesan ya estandarte na bansa ya “General Valve Mark” GB 12220. Parad saray balbula ya walay working pressure ya mas atagey nen say 1.0 MPa tan man-cutting off ed manunan tubo, kaukolan ya suboken so biskeg tan malet ya performance antis ya i-install tan usaren ya kwalipikado. Diad strength test, say test pressure et 1.5 beses na nominal pressure, tan say karukey to et ag onkulang ed 5 min. Say valve shell tan say packing et nepeg ya kualipikado ya anggapoy leakage. Parad tightness test, say test pressure et 1.1 beses na nominal pressure; say test pressure et nepeg ya makaabot ed GB 50243 ya estandarte ed karukey na test, tan say tapew na valve seal et kualipikado.
Say pampili na produkto na saray manunan punto
1. Say manunan control parameters na butterfly valve et saray detalye tan sukat.
2. Say butterfly valve et sakey a plate wind valve, simpli so istruktura to, kombenientin prosesoen, abeba so gastos to, simpli so operasyon to, balet say inkasusto na panag-adjust to et makapuy, matukoy labat parad bentilasyon tan air conditioning system parad switch odino magaspang ya adjustment na okasyon.
3. Nayarin manual, electric o zipper type ya operasyon, nayarin i-fix ed antokaman ya Angle ya 90 range.
4. Lapud saksakey ya axial ya saksakey a plato na balbula, say puersa na bearing et limitado, diad kondisyon na baleg a pandumaan na presyon, baleg so agos no antikey so bilay na balbula. Say balbula et walay sarado ya klase tan ordinaryon klase, insulation tan non-insulation.
5. Say electric butterfly valve et walaan labat na duaran klase na kontrol, say electric actuator et pareho ed multi-leaf valve.
