Dakal la reng klasing butterfly valves, at dakal la reng paralan ning pamag-classify.
1. Pamag-classify agpang keng structural form
(1)concentric butterfly valve; (2) single-eccentric butterfly valve; (3) dobli-eccentric butterfly valve; (4) atlung-eksentrik a balbula ning parul
2. Pamag-classify agpang keng sealing surface material
(1) Resilient butterfly valve
(2) Metal-type hard-sealed butterfly valve. Ing sealing pair metung yang metal hard material keng metal hard material.
3. Pamagklasipika kapamilatan ning makatatak a porma
(1) Pilit a makasara a balbula ning parul.
(2) Pressure sealing butterfly valve. Ing seal pressure gagawan ne ning elastic sealing element keng luklukan o platu.
(3) Automatic sealed butterfly valve. Ing seal specific pressure automatic yang gagawan ning medium pressure.
4. Pamagklasipika agpang king presyur ning obra
(1) Ing vacuum butterfly valve. Butterfly valve na ating working pressure a mas mababa kesa keng standard a atmosphere.
(2) Low-pressure butterfly valve. Butterfly valve a maki nominal a pressure a PN≤1.6MPa.
(3) Medium-pressure butterfly valve. Ing nominal pressure PN yapin ing butterfly valve a 2.5∽6.4MPa.
(4) High-pressure butterfly valve. Ing nominal pressure PN yapin ing butterfly valve a 10.0∽80.OMPa.
(5) Ultra-high pressure butterfly valve. Butterfly valve a maki nominal a pressure PN <100MPa.
5. Pamagklasipika agpang keng paralan ning pamagkonekta
(1)Wafer butterfly valve
(2) Flange butterfly valve
(3) Lug butterfly valve
(4) Welded butterfly valve
Ing concentric Butterfly valve metung yang klasing valve na magbukas ampo magsara gamit ing circular butterfly plate ampo magbukas, magsara ampo mag-adjust keng fluid channel keng pamag-ikot ning valve stem. Ing butterfly plate ning butterfly valve maka-install ya keng diameter direksyun ning pipe. keng cylindrical channel ning butterfly valve body, ing disc butterfly plate mag rotate ya keng axis, ampo ing rotation Angle atyu ya pilatan ning 0 ampo 90. Potang ing rotation miras yang 90, ing valve lubus yang makabuklat.
Deng susi ning konstruksyun ampo pamag install
1) Ing posisyun ning pamag-install, katas, direksyun ning pamag-import ampo pamag-export dapat makatupad ya kareng requirements ning design, ampo ing koneksyun dapat matatag ya at masipit.
2) Ing hawakan da reng sablang uri da reng manual a balbula a maka-install keng thermal insulation pipe e dapat pababa.
' keng strength test, ing test pressure 1.5 times ya keng nominal pressure, ampo ing duration ali ya mas ditak keng 5min. Ing valve shell ampo ing packing dapat qualified lang alang leakage. Para keng tightness test, ing test pressure 1.1 times ya keng nominal pressure; ing test pressure dapat makatupad ya keng GB 50243 standard para keng duration ning test, ampo ing valve seal surface kwalipikadu ya.
Pamili ning produktu da reng susi
1. Ing main control parameters ning butterfly valve ilapin deng specifications ampo dimensions.
2. Ing butterfly valve metung yang single plate wind valve, ing kayang simpleng istruktura, manyaman ing pamagprosesu, mababa ing gastus, simple ing operasyun, pero ing adjustment accuracy e ya masanting, masanting ya para keng ventilation ampo air conditioning system para keng switch o coarse adjustment ning okasyun.
3. Malyari yang manual, electric o zipper type operation, malyari yang ayusan keng nanu mang Angle of 90 range.
4. Uling keng metung a axial single valve plate, ing bearing force limitadu ya, keng kundisyun ning maragul a pressure difference, maragul a flow rate nung ing valve service life makuyad ya. Ing balbula atin yang saradung uri ampo ordinaryung uri, insulation ampo non-insulation.
5. Ing electric butterfly valve atin yang dual type control, ing electric actuator parehu ya keng multi-leaf valve.
