Lug vs. Wafer Butterfly Valves: Key Differences & Guide

Balbula da reng parulatin yang maragul a papil keng pamagkontrol keng dagul da reng miyayaliwang likidu ampo gas. Kareng miyayaliwang uri da reng butterfly valves, lug butterfly valves ampo ing waferbalbula ning paruladwa lang maralas dang gagamitan a pilinan. Deng adwang uri da reng balbula atin lang miyayaliwang obra at masanting la para kareng partikular a aplikasyun.TWSabalu mi ing karelang pamikakametung ampo pamiyaliwa keng artikulung ayni, asahan mi na makasaup keka para makagawa kang masaleseng desisyun nung mamili kang ustung balbula.

I. Ing pamikakametung da.

1. MagobraPprinsipyu.

Parehu lang wafer type butterfly valves ampo lug type butterfly valves a magkontrol keng flow rate ning medium kapamilatan ning pamag-rotate keng valve disc. Ing rotation angle ning valve disc malyari ya mung atyu pilatan ning 0 anggang 90 degrees, buri ng sabyan, ing valve makabuklat ya keng 90 degrees ampo makasara ya keng 0 degrees. ini ing prinsipyu ning obra da reng butterfly valves.

2. ParehuHarapan Harapan

Ing wafer butterfly valve ampo ing lug butterfly valve dinisenyu la bilang manipis a uri, na mas ditak ing sasakupan dang espasyu ampo masanting lang i-install keng pipeline system na ating limitadu a espasyu.

3. Standardized a disenyu:

Parehu lang makatupad kareng international industrial standards, madali lang ikonekta kareng standard flanges, ampo malyari lang palitan kareng existing a sistema.

II.Nanu's ing pamiyaliwa?

Parehu lang wafer type butterfly valves ampo lug type butterfly valves ing tuturu da keng koneksyun da reng butterfly valves, parehu ing kaba ning istruktura ampo parehu ing sangkan, pero atin lang maragul a pamiyaliwa keng disenyu, pamag-install, pamag-apply, gastus, ampo aliwa pang aspetu.

1.DisenyuDpamiyaliwa

Lug butterfly valve: Deng adwang wakas ning katawan ning valve dinisenyu la kareng threaded lugs, na mas masanting para a-ayus ing valve.

Wafer butterfly valve: Ing kabaligtaran, ala yang threaded inserts, pero maka-clamp ya pilatan da reng adwang flanges, a maki bolts a dadalan keng pipeline flange ampo keng valve body para ayusan de. Buri ng sabyan, dinisenyu ne ning pressure da reng bolts a mag-squeeze keng pipeline flange.

2.InstallPprosesu.

• Lugbalbula ning parul:

Deng lug butterfly valves masanting la para kareng pipeline na mangailangan regular a pamag-maintain o maralas a pamag-disassemble. Deng threaded inserts madali lang i-install ampo i-disassemble na alang masira keng mabilug a pipeline system. Ing protruding butterfly valve malyari yang i-install keng wakas ning pipeline ampo gamitan ya bilang terminal valve.

- Siguradwan na ing lugs makalinya ya keng flange bolts para aiwasan ing pressure keng valve body.

- Gamitan ing ustung gasket materials nung kailangan para aiwasan ing leakage, lalu na kareng medium pressure systems.

- Ihigpitan la reng bolts para pare-pareu ing pressure kilub ning balbula.

• Waferbalbula ning parul:

Deng wafer butterfly valves mas masanting la para keng pamagkonekta kareng adwang wakas da reng pipeline kareng sitwasyun nung nukarin limitadu ing espasyu, pero e la malyaring gamitan bilang terminal valves uling malyari lang mikakawani.

- I-verify ing flange compatibility (eg ANSI, DIN) para makasiguradung maka-seal ya.

- Iwasan ing sobrang pamaghigpit kareng flange bolts para aiwasan ing deformation ning katawan ning makina.

- Maka-install ya keng sistema na ating minimal a pipeline vibration para e ya maluwag.

3. Mekanismo ning Pamag-seal.

Ing lug butterfly valve mamye yang mas masipit a seal pauli da reng threaded connections ampo safety bolts, makasiguradung alang leak a operasyun ampo makaiwas keng fluid backflow.

Ing kabaligtaran, ing wafer type butterfly valve magdependi ya keng compression pilatan da reng adwang flange para mika reliable sealing, inya kailangan yang i-install a ganap a maka-align keng pipeline para aiwasan ing misalignment ampo leakage.

4. DN&PN

- Deng wafer on butterfly valves keraklan mas malati la kesa keng DN600, ampo deng single flange butterfly valves malyari lang gamitan para kareng mas maragul a diametru. Keraklan, masanting la kareng sitwasyun nung nukarin ing pressure ≤ PN16 ya.

-Ing lug butterfly valve mas maragul ya diametru at agyu nang tanggapan ing mas matas a pressure levels, anggang PN25, uling mas ligtas ya ing pamag-install king lug butterfly valve.

5. Cost

Deng lug butterfly valves ampo reng wafer butterfly valves miyayaliwa la keng cost-effectiveness.

Deng wafer butterfly valves keraklan mas matipid la uling mas simple la disenyu, mas simple ing pamagprosesu, ampo mas ditak ing kailangan dang materyal.

Ing lug butterfly valve mangailangan yang threading, inya ing prosesu ning pamag-machine medyu komplikadu ya.

III. Ckonklusyun

Parehu lang gagamitan deng lug butterfly valves ampo wafer butterfly valves para makontrol ing dagul ning likidu, pero atin lang maragul a pamiyaliwa keng disenyu, pamag-install, pamag-seal, diameter, pressure rating, ampo ing gastus da reng adwang deti. Nung mamili, malyari yang abalu agpang kareng partikular a pamangailangan: nung kailangan ing maralas a pamag-disassemble ampo pamag-maintain, masanting ing mamili kang protruding ear type; nung masipit ya ing espasyu ampo ing gastus metung yang concern, ing wafer on design mas masanting ya. Ing pamangilala kareng pamiyaliwa a reni makasaup keka para mamili kang mas compatible a balbula ampo makakwa kang efficient ampo reliable a pamagkontrol keng danum.TWSali yamu metung a mapanalig a partner para keng matas a kalidadbalbula ning parul, pero atin ya namang malalam a teknikal a pamitipun ampo mature a solusyun keng larangan ninggate valves, check valves, balbula ning pamagluwal angin, etc. Agyang nanu pang fluid control ing kailangan mu, agyu mi kang dinan propesyonal at kumpletung one-stop valve support. nung atin kang balak makipagsaup o technical consultation, malyari kang makipagsalita kekami nanu mang oras.
