Ing balbula bilang kasangkapan mibait ya kilub ning libu-libung banua

Ing balbulametung yang kasangkapan a magagamit king pamagdala at pamagkontrol king gas ampong likidu a maki e kumulang king libung banuang amlat.

Ngeni, keng fluid pipeline system, ing regulating valve ya ing control element, at ing peka-obra na yapin ing mag-isolate kareng equipment ampo ing pipeline system, mag-regulate keng flow, mag-iwas backflow, mag-regulate ampo mag-discharge keng pressure. Uling importanti ing mamili keng pekamasanting a regulating valve para keng sistema ning pipeline, importanti ya naman ing aintindian ing katangian ning balbula ampo reng lakbang ampo ing basi para mamili keng balbula.

Nominal pressure ning balbula

Ing nominal a pressure ning balbula mangabaldugan yang disenyu a binie ning presyur a maki kaugnayan king sikanan da reng sangkap ning pipa, buri nang sabyan, iti ing paintulutan a pressure ning balbula king metung a temperatura, a maki kaugnayan king materyales ning balbula. Ing pressure ning obra ali ya parehu, inya, ing nominal a pressure metung yang parameter na makadependi keng materyales ning balbula at makasuglung ya keng paintulutan a temperatura ning obra ampo ing pressure ning materyales.

Ing valve metung yang pasilidad keng medium circulation system o pressure system, na magagamit para a-adjust ing danum o pressure ning medium. Deng aliwang gagawan na ilapin deng pamagsara o pamag-switch on keng media, pamagkontrol keng daloy, pamagbayu keng direksyun ning daloy ning media, pamag-iwas keng media backflow, ampo pamagkontrol o pamag-vent pressure.

Deting obra agawa la kapamilatan ning pamag-adjust king posisyun ning pamagsara ning balbula. Ing pamagbayu ayni malyari yang gawan manual o automatic. Ing manual a operasyun kayabe ya ing operasyun ning manual a pamagkontrol keng drive. Deng manual operated valves awsan dong manual valves. Ing balbula na makapigil keng pamagbalik ning danum mayayaus yang check valve; ing metung a magkontrol keng relief pressure awsan deng safety valve o safety relief valve.

angga ngeni, ing industriya ning balbula mekapagproduce yang ganap a uri ninggate valves, globe valves, throttle valves, plug valves, ball valves, electric valves, diaphragm control valves, check valves, safety valves, pressure reducing valves, steam traps ampo emergency shut-off valves. Valve products of 12 categories, maygit 3000 models, ampo maigit 4000 specifications; ing maximum a pressure ning obra 600MPa ya, ing maximum a diametru 5350mm ya, ing maximum a temperatura ning obra 1200 ya°C, ing minimum a temperatura ning obra -196 ya°C, at ing applicable medium yapin ing danum, steam, oil, natural gas, masikan a corrosive media (antimo ing concentrated nitric acid, medium concentration sulfuric acid, atbp.).

pansinan ing pamamili keng balbula:

1. Para mabawas ing lalam ning pipeline,ing balbula ning parulkeraklan mapipili ya para keng mas maragul a diametru ning pipeline; ing pekamaragul a disbentaha ning butterfly valve yapin ing ing butterfly plate sasakupan ne ing metung a cross section ning danum, a magdalang metung a head loss;

2. Deng konbensyunal a balbula kayabe labalbula ning parul, gate valves, ball valves ampo plug valves, etc. Ing range da reng valves a gagamitan keng water supply network dapat yang ikonsidera keng pamili.

3. Ing pamag-cast ampo pamagprosesu kareng ball valves ampo plug valves masakit la ampo mamasa, ampo keraklan para la kareng malati ampo katamtaman a diameter a tubo. Ing ball valve ampo ing plug valve atin lang advantage ning single gate valve, malating water flow resistance, reliable a sealing, flexible action, manyaman a operasyun ampo maintenance. Ing plug valve atin yang parehung advantage, pero ing water-passing section ali ya perpektung gulis.

4. nung ala yang epektu keng lalam ning gabun a tatakpan, subukan mung mamili keng gate valve; ing katas ning electric gate valve large-diameter vertical gate valve makaapektu ya keng soil-covering depth ning pipeline, ampo ing kaba ning maragul a diameter horizontal gate valve daragdagan ne ing horizontal area a sasakupan ning pipeline ampo makaapektu ya keng panga-ayus da reng aliwang pipeline ;

5. Kareng milabas a banua, pauli ning pamagbayu ning teknolohiya ning pamag-cast, ing pamangamit king resin sand casting malyari yang makaiwas o mabawas ing pamagprosesu king mekanikal, inya sa’t mabawas ing gastus, inya ing panga-magamit da reng ball valves a gagamitan kareng mangaragul a diametru a pipeline dapat yang abalu. Para keng demarcation line ning calibre size, dapat yang ikonsidera at pipartian agpang keng partikular a sitwasyun.
