Pamipakilala kareng karaniwan a balbula

Dakal la reng uri at komplikadung uri ningbalbula, keraklan kayabe la reng gate valves, globe valves, throttle valves, butterfly valves, plug valves, ball valves, electric valves, diaphragm valves, check valves, safety valves, pressure reducing valves, steam traps ampo emergency shut-off valves, atbp., na keraklan gagamitan gate valve, glottle valve, butterfly valve, butterly valve balbula, balbula de bola, balbula de check, balbula de diaphragm.

1 Balbula ning parul
Ing butterfly valve yapin ing pamagbukas ampo pamagsara ning butterfly plate a malyaring makumpletu kapamilatan ning pamag-rotate 90° king paligid ning fixed axis king katawan ning valve. Ing butterfly valve malati ya, magaan ya at simple ya istruktura, at atin yang mapilan a bage. at kailangan mung mag rotate 90°; mabilis yang mabuklat at isara, at simpli ya ing operasyun. Nung ing butterfly valve atyu ya keng ganap a makabuklat a posisyun, ing kapal ning butterfly plate ya ing bukud mung resistance nung ing medium mamagus ya keng katawan ning valve, inya ing pressure drop a gagawan ning valve malati ya, inya mas masanting ya ing flow control characteristics. Ing butterfly valve makadake ya keng elastic soft seal ampo metal hard seal. Elastic sealing valve, ing sealing ring malyari yang i-inlaid keng katawan ning valve o iyabe ya keng periphery ning disc, a maki masanting a pamag-sealing, na malyaring gamitan para keng throttling, medium vacuum pipelines ampo corrosive media. Deng balbula a ating metal a seal keraklan mas makaba la bie kesa kareng ating elastic a seal, pero masakit lang akwa deng kumpletung seal. Keraklan magagamit la kareng okasyun a maragul a pamagbayu keng danum ampo pressure drop ampo mangailangan lang masanting a throttling performance. Deng metal a seal malyari lang makibagay kareng mas matas a temperatura, kabang deng elastic a seal atin lang depektu na limitadu la keng temperatura.

2Gate valve
Ing gate valve mangabaldugan yang balbula na ing kayang makabuklat ampo makasara a katawan (valve plate) tutulak ne ning valve stem ampo kikimut ya patas at pababa keng sealing surface ning valve seat, na malyaring magkonekta o magputol keng dalan ning fluid. Nung ikumpara me keng globe valve, ing gate valve mas masanting ya keng pamag-seal, mas ditak ing fluid resistance, mas ditak ing effort para buklat ampo isara, ampo atin yang adjustment performance. Metung ya kareng peka maralas dang gagamitan a block valves. Ing disbentaha na, maragul ya sukad, mas komplikadu ya ing istruktura kesa keng globe valve, ing sealing surface madali yang isulud, ampo e ya madaling mantenidwan. Keraklan, ali ya masanting para keng throttling. Agpang keng posisyun ning sinulad keng gate valve stem, makadake ya keng adwang uri: open rod type ampo dark rod type. Agpang keng structural characteristics ning gate, malyari yang miyabe keng adwang uri: wedge type ampo parallel type.

3 Check valve
Ing check valve metung yang valve na automatic yang makapigil keng pamagbalik ning fluid. Ing valve flap ning check valve mibuklat ya lalam ning aksyon ning fluid pressure, at ing fluid mamagus ya manibat keng inlet side papunta keng outlet side. Nung ing pressure keng inlet side mas mababa ya kesa keng outlet side, ing valve flap automatic yang magsara keng aksyon ning fluid pressure difference, ing sarili nang gravity ampo reng aliwang sangkan para e ya mibalik ing fluid. Agpang keng istruktura, malyari yang miyabe keng lift check valve ampo swing check valve. Ing lift type atin yang mas masanting a sealing performance ampo mas maragul a fluid resistance kesa keng swing type. Para keng suction port ning suction pipe ning pump, ing bottom valve ing dapat pilinan. Ing kayang obra yapin ing katmuan ne ing inlet pipe ning pump keng danum bayu ya magumpisa ing pump; panatilyan ing inlet pipe ampo ing katawan ning pump a mitmung danum kaybat nang tinuknang ning pump, ban makasadya yang mag-restart pasibayu. Ing bottom valve keraklan maka-install ya keng vertical pipeline ning pump inlet, at ing medium mamagus ya manibat lalam papunta babo.

4 Globe valve
Ing globe valve metung yang pababa a makasara a balbula, at ing makabuklat at makasara a miyembru (valve) tutulak ne ning valve stem ba yang mibaba at mibaba king axis ning valve seat (sealing surface). Nung ikumpara me keng gate valve, atin yang masanting a pamag-adjust, e masanting ing pamag-seal, simple ing istruktura, manyaman ing pamaglalang ampo pamag-maintain, maragul ing fluid resistance ampo mababang presyu.

5 Ball valve
Ing makabuklat ampo makasara nang dake ning ball valve metung yang sphere a maki circular through hole, at ing sphere mag rotate ya keng valve stem para abalu ing makabuklat ampo makasara ya ing valve. Ing ball valve atin yang simpleng istruktura, mabilis a pamagbayu, manyaman a operasyun, malati ya sukad, magaan ya timbang, ditak la mu reng bage, malati ya ing fluid resistance, masanting a pamag-seal ampo manyaman a pamag-maintain.

6 Throttle valve
Ing istruktura ning throttle valve parehu ya keng globe valve maliban keng valve disc. Ing valve disc metung yang throttling component, at miyayaliwang porma atin lang miyayaliwang katangian. Ing diametru ning luklukan ning balbula e dapat masyadung maragul, uling malati ya ing katas ning pamuklat. Ing medium flow rate daragul ya, kaya mabilis ing erosion ning valve disc. Ing throttle valve atin yang malating sukad, magaan a timbang ampo masanting a pamag-adjust, pero ing pamag-adjust ali ya matas.

7 Plug valve
Ing plug valve gagamit yang plug body a maki through hole bilang pamuklat at pamagsara nang bage, at ing plug body mag rotate ya keng valve stem para abalu ing pamagbukas ampo pamagsara ning valve. Ing plug valve atin yang advantage keng simpleng istruktura, mabilis a pamag switch, manyaman a operasyun, malating fluid resistance, ditak a bage ampo magaan a timbang. Atin yang straight-through, atlung-dalan ampo apat a-dalan a plug valves. Ing straight-through plug valve magagamit ya para pututan ing medium, at deng three-way ampo four-way plug valves gagamitan de para alilan ing direksyun ning medium o pamikawani da reng medium.

8 Diaphragm valve
Ing makabuklat ampong makasara nang dake ning balbula ning diaphragm metung yang diaphragm a goma, a maka-sandwich king pilatan ning katawan ning balbula ampo ing takpan ning balbula. Ing libutad a makalwal a dake ning diaphragm makabili ya keng valve stem, ampo ing katawan ning valve makalinya ya keng goma. Uling ing medium e ya lulub keng kilub ning lukib ning valve cover, ing valve stem e na kailangan ing stuffing box. Ing diaphragm valve atin yang simpleng istruktura, masanting a pamag-seal, madali yang maintenance ampo malating fluid resistance. Deng diaphragm valves makadake la keng weir type, straight-through type, right-angle type ampo direct-flow type.
