Lihlopha tsa Sebopeho sa Li-valve tsa Butterfly

Li-valve tsa butterfly li arotsoe ho latela moralo oa tsona, lisebelisoa le mekhoa ea khokahano:

1. Ka Ho tsamaisana ha Disc

- Sesepa sa Serurubele se Concentric (Setulo se Resilient):Moqapi o bonolo ka ho fetisisa, o nang le disk e tsepamisitsoeng ka har'a pipe bore. E loketse lits'ebetso tsa khatello e tlase.

- Valve ea Serurubele sa Eccentric (Ts'ebetso e Phahameng):Diski e tlosoa ho tloha setsing sa pipe, ho fokotsa ho apara le ho nolofalletsa ho mamella khatello e phahameng.

- Triple Eccentric Butterfly Valve:E na le sebaka sa "conical disc seating surface" bakeng sa ho lutla ha zero maemong a feteletseng (mohlala, mocheso o phahameng / likhatello).

2. Ka Boitsebiso

- Lisebelisuoa tsa 'Mele:Cast iron, stainless steel, ductile iron, PVC, kapa nickel alloys.

- Lisebelisoa tsa Setulo:EPDM, Viton, PTFE (bakeng sa khanyetso ea lik'hemik'hale).

3. Ka Mofuta oa Khokahano

- Li-valve tsa Wafer Butterfly:E kentsoeng pakeng tsa liphaephe tse nang le liphaephe.

- Li-valve tsa Lug Butterfly:Mehaho ea likhoele bakeng sa likhokahano tsa bolt.

- Flanged Butterfly Valve:Li-flange tse kopantsoeng bakeng sa liphaephe tse tobileng.

Melemo ea Li-valve tsa Butterfly

Li-valve tsa butterfly li ratoa lefatšeng ka bophara bakeng sa tsona:

- Moralo oa Compact:E hloka sebaka se fokolang sa ho kenya.

- Ts'ebetso e potlakileng:Potoloho ea 90-degree e nolofalletsa ho bula / ho koala kapele.

- Litšenyehelo:Litšenyehelo tse tlase tsa thepa le tlhokomelo ho feta li-valve tsa heke/globe.

- Mefuta-futa:E loketse li-diameter tse kholo tsa liphaephe le mecha ea litaba e fapaneng.

- Ho theoha ha Khatello e Tlase:Ho hanyetsa ho phalla ho fokolang ha ho bulehile ka ho feletseng.

Li-valve tsa serurubele li sebetsa mesebetsi ea bohlokoa liindastering tsohle:

1. Phekolo ea Metsi le Litšila

- Laola phallo ea metsi ka liphaephe, lipompo le litanka.

- E sebelisoa lits'ebetsong tsa ho hloekisa, ho tsamaisa le ho tsamaisa metsi.

2. Oli le Khase

- Laola oli e tala, khase ea tlhaho le lihlahisoa tse hloekisitsoeng.

- Li-valve tse tharo tsa eccentric li sebetsana le liphaephe tsa khatello e phahameng.

3. Tšebeliso ea Lik'hemik'hale

- Li-valve tse nang le PTFE li laola metsi a senyang.

4. Litsamaiso tsa HVAC

- Ho leka-lekanya ho futhumatsa / ho pholile mecha ea litaba mehahong ea khoebo.

5. Lijo & Seno

- Li-valve tsa bohloeki li netefatsa ts'ebetso ea bohloeki.

6. Tšireletso ea Mollo

- Li-valve tse ikemetseng li kenya tšebetsong litsamaiso tsa ho fafatsa.
