Li-valve tsa Serurubele sa Lug khahlanong le Wafer: Liphapang tsa Bohlokoa le Tataiso

Li-valve tsa serurubelee bapala karolo ea bohlokoa ho laoleng phallo ea metsi le likhase tse fapaneng. Har'a mefuta e fapaneng ea li-valve tsa lirurubele, li-valve tsa lirurubele tsa lug le waferli-valve tsa serurubeleke dikgetho tse pedi tse sebediswang haholo. Mefuta ka bobedi ya di-valve e na le mesebetsi e ikgethang mme e loketse ditshebediso tse ikgethang.TWSSehloohong sena re tla hlahloba ho tšoana le ho se tšoane ha tsona, re tšepa ho u thusa ho etsa liqeto tse nang le tsebo ha u khetha valve e nepahetseng.

I. Ho tšoana ho teng pakeng tsa tsona.

1. Ho sebetsaPrinciple.

Li-valve tsa serurubele tsa mofuta oa wafer le li-valve tsa serurubele tsa mofuta oa lug li laola sekhahla sa phallo ea seaplane ka ho potoloha disc ea valve. Sekhutlo sa potoloho ea disc ea valve e ka ba pakeng tsa likhato tse 0 ho isa ho tse 90 feela, ho bolelang hore valve e bulehile ka botlalo likhatong tse 90 'me e koetsoe ka botlalo likhatong tse 0. Ena ke molao-motheo o sebetsang oa li-valve tsa serurubele.

2. E tšoanangLifahleho li talimane

Valve ea serurubele sa wafer le valve ea serurubele ea lug li entsoe ka mofuta o mosesaane, tse nkang sebaka se senyenyane 'me li loketse ho kenngoa tsamaisong ea liphaephe tse nang le sebaka se fokolang.

3. Moralo o tloaelehileng:

Ka bobeli li latela maemo a indasteri a machaba, li bonolo ho hokahanngoa le li-flange tse tloaelehileng, 'me li ka nkeloa sebaka habonolo litsamaisong tse seng li ntse li le teng.

II.Eng's phapang?

Li-valve tsa serurubele tsa mofuta oa wafer le li-valve tsa serurubele tsa mofuta oa lug li bua ka mofuta oa khokahano ea li-valve tsa serurubele, tse nang le bolelele bo tšoanang ba sebopeho le merero e ts'oanang, empa ho na le phapang e kholo moralong, ho kenya, ts'ebelisong, litšenyehelong le likarolong tse ling.

1.MoraloDlitšupiso

Valve ea serurubele sa Lug: Lipheletso ka bobeli tsa 'mele oa valve li entsoe ka li-lug tse nang le khoele, tse thusang haholoanyane ho lokisa valve.

Valve ea serurubele sa Wafer: Ho fapana le hoo, ha e na li-insert tse nang le khoele, empa e khomaretsoe pakeng tsa li-flange tse peli, ka liboutu tse fetang ka har'a flange ea phaephe le 'mele oa valve ho e lokisa. Ke hore, e entsoe ka khatello ea liboutu tse hatellang flange ea phaephe.

2.Ho kenyaPtsamaiso.

• Mokotlavalve ea serurubele:

Li-valve tsa lirurubele tsa Lug li loketse liphaephe tse hlokang tlhokomelo e tloaelehileng kapa ho qhaqhoa khafetsa. Li-insert tse nang le khoele li bonolo ho li kenya le ho li qhaqha ntle le ho senya tsamaiso eohle ea liphaephe. ​​Valve ea lirurubele e hlahelletseng e ka kenngoa qetellong ea phaephe 'me ea sebelisoa e le valve ea terminal.

- Netefatsa hore li-lug li hokahane hantle le li-bolt tsa flange ho qoba khatello 'meleng oa valve.

- Sebelisa thepa e loketseng ea gasket ha ho hlokahala ho thibela ho lutla, haholo-holo lits'ebetsong tsa khatello e mahareng.

- Tiisa diboutu ka ho lekana ho boloka kgatello e tshwanang ka hare ho valve.

• Wafervalve ea serurubele:

Li-valve tsa serurubele sa wafer li loketse haholoanyane ho hokahanya lipheletso ka bobeli tsa liphaephe maemong ao sebaka se fokolang, empa li ke ke tsa sebelisoa e le li-valve tsa terminal kaha li ka 'na tsa arohana.

- Netefatsa ho lumellana ha flange (mohlala, ANSI, DIN) ho netefatsa ho kwala.

- Qoba ho tiisa liboutu tsa flange haholo ho thibela ho fetoha ha 'mele oa mochini.

- E kentswe tsamaisong ka ho thothomela ho fokolang ha diphaephe ho thibela ho hlepha.

3. Mokhoa oa ho Tiisa.

Valve ea serurubele sa lug e fana ka tiiso e tiileng haholoanyane ka lebaka la likhokahano tse nang le khoele le liboutu tsa polokeho, e netefatsang ts'ebetso e se nang ho lutla le ho thibela phallo ea metsi hape.

Ho fapana le hoo, valve ea serurubele ea mofuta oa wafer e itšetlehile ka khatello pakeng tsa li-flange tse peli ho fihlela ho koaloa ho tšepahalang, kahoo e hloka ho kenngoa ka botlalo ho latela phaephe ho qoba ho se lumellane hantle le ho lutla.

4. DN&PN

- Wafer e hodima di-valve tsa serurubele hangata e nyane ho feta DN600, mme di-valve tsa serurubele tse nang le flange e le nngwe di ka sebediswa bakeng sa bophara bo boholo. Ka kakaretso di loketse maemo ao kgatello e leng ≤ PN16.

-Valve ea serurubele sa lug e na le bophara bo boholo 'me e ka sebetsana le maemo a phahameng a khatello, ho fihlela ho PN25, hobane ho kenngoa ha valve ea serurubele sa lug ho sireletsehile haholoanyane.

5. Cboholo

Li-valve tsa lirurubele tsa Lug le li-valve tsa lirurubele tsa wafer li fapana ka katleho ea litšenyehelo.

Li-valve tsa serurubele sa wafer hangata li theko e tlase hobane li na le meralo e bonolo, ts'ebetso e bonolo, 'me ha li hloke thepa e ngata.

Valve ea serurubele sa lug e hloka ho kobeha khoele, kahoo ts'ebetso ea ho sebetsa e rarahane haholo.

III. Csephetho

Li-valve tsa serurubele tsa lug le li-valve tsa serurubele tsa wafer ka bobeli li sebelisetsoa ho laola phallo ea mokelikeli, empa ho na le liphapang tse kholo moralong, ho kenya, ho tiisa, bophara, tekanyo ea khatello, le litšenyehelo lipakeng tsa tsena tse peli. Ha u khetha, e ka khethoa ho latela litlhoko tse itseng: haeba ho hlokahala ho qhaqhoa le ho hlokomeloa khafetsa, ho eletsoa ho khetha mofuta oa tsebe e hlahelletseng; Haeba sebaka se le thata 'me litšenyehelo e le bothata, wafer e moralong e loketse haholoanyane. Ho utloisisa liphapang tsena ho ka u thusa ho khetha li-valve tse lumellanang haholoanyane le ho fihlela taolo e sebetsang hantle le e tšepahalang ea phallo.TWSha se feela molekane ea tšepahalang bakeng sa boleng bo holimoli-valve tsa serurubele, empa hape e na le pokello e tebileng ea tekheniki le litharollo tse butsoitseng masimong ali-valve tsa heke, li-valve tsa ho hlahloba, valve ea ho lokolla moeajj. Ho sa tsotelehe hore na taolo ea mokelikeli e u hloka eng, re ka u fa tšehetso ea profeshenale le e felletseng ea valve ea ho emisa hang.
