Li-valve tsa butterflyli fumaneha hohle lits'ebetsong tsa indasteri 'me ke karolo ea bohlokoa ho laola phallo ea maro a fapaneng liphaepheng.Ntho e ka sehloohong eo u ka e nahanang ha u khetha le ho sebelisa valve ea serurubele ke tekanyo ea eona e phahameng ea khatello.Ho utloisisa tekanyo ena ho bohlokoa ho netefatsa ts'ebetso e bolokehileng le e sebetsang ea litsamaiso tsa mokelikeli.
Sehloohong sena, re tla shebana le mohopolo oa tekanyo e phahameng ea khatello eo valve ea serurubele e ka e mamellang, le ho ithuta phello ea khatello e lekantsoeng ho tsoa likarolong tse kang moralo oa li-valve tsa serurubele, thepa, ho tiisa, joalo-joalo.
Khatello e phahameng ke efe?
Tekanyo e phahameng ea khatello ea valve ea serurubele e bolela khatello e phahameng ka ho fetisisa eo valve ea serurubele e ka sebetsang ka mokhoa o sireletsehileng ntle le ho se sebetse kapa ho ama ts'ebetso.Lintlha tse latelang ke tse 'maloa tse khethollang tekanyo e phahameng ea khatello ea valve ea serurubele
1. Lisebelisoa tsa valve ea butterfly
Lisebelisoa tse sebelisetsoang ho etsa 'mele oa valve, plate ea valve, stem ea valve le setulo sa valve ke lintlha tse ka sehloohong tse khethollang boemo ba khatello ea serurubele.Lisebelisoa tse nang le matla a phahameng a ho tsitsa, ho hanyetsa kutu le botsitso ba mocheso li ka mamella likhatello tse phahameng.Ka mohlala, li-valve tsa serurubele sa tšepe e sa hloekang li ka mamella likhatello tse phahameng ka lebaka la ho hanyetsa ha tsona ho matla le matla a tsona.
Thesetulo sa valvethepa ya ho tiisae tla boela e ama matla a jereng khatello ea valve ea serurubele.Ka mohlala, EPDM, NBR, joalo-joalo ke lisebelisoa tse atisang ho sebelisoa ho tiisa rabara, empa matla a tsona a ho mamella khatello a batla a lekanyelitsoe.Bakeng sa lisebelisoa tse hlokehang ho mamella likhatello tse phahameng, lisebelisoa tse ling tsa ho tiisa tse sa keneleng khatello li ka khethoa.
2. Sebopeho sa valve ea butterfly
Sebopeho sa valve ea serurubele ke ntlha e 'ngoe ea bohlokoa e amang khatello ea serurubele.Ka mohlala, valve ea "centerline soft-sealing butterfly valve" hangata e sebelisoa mekhoeng e tlaase ea khatello, e leng PN6-PN25.Moralo oa li-valve tsa serurubele tse nang le likarolo tse peli o ntlafatsa ts'ebetso ea ho koala ka ho fetola sebopeho sa poleiti ea serurubele le setulo sa valve ho mamella khatello e kholo.
3. Butterfly belofo 'mele lebota botenya
Ho na le kamano e lekanang pakeng tsa boholo ba botenya ba lerako la 'mele oa valve le khatello.Ka tloaelo ha sekhahla sa khatello ea valve se ntse se eketseha, 'mele oa serurubele o motenya o khona ho amohela matla a teng ha khatello ea mokelikeli e eketseha.
4. Litekanyetso tsa moralo oa khatello ea li-valve tsa butterfly
Litekanyetso tsa moralo oa valve ea serurubele li tla totobatsa khatello e phahameng eo e ka e mamellang.Li-valve tsa Butterfly li entsoe ho latela API (American Petroleum Institute), ASME (American Society of Mechanical Engineers), ISO (Mokhatlo oa Machaba oa Boemo) le litekanyetso tse ling tsa indasteri, 'me li hlahlojoa ka thata le ho hlahlojoa ho netefatsa hore valve ea serurubele e finyella se boletsoeng. boemo ba khatello.
Na Li-valve tsa Butterfly li Molemo Bakeng sa Khatello e Phahameng?
Li-valve tsa serurubele li ka aroloa ka li-valve tsa serurubele sa vacuum, li-valve tsa serurubele se nang le khatello e tlase, li-valve tsa serurubele se nang le khatello e mahareng, le li-valve tsa serurubele se nang le khatello e phahameng ho latela khatello ea lebitso.
1).Vacuum butterfly valve — valve ea serurubele eo khatello ea eona ea ho sebetsa e leng tlaase ho feta khatello e tloaelehileng ea sepakapaka.
2).Serurubele sa khatello e tlasebelofo- valve ea serurubele e nang le khatello ea lebitso PN e ka tlase ho 1.6MPa.
3).Belofo ea serurubele sa khatello e mahareng—valve ea serurubele e nang le khatello ea lebitso PN 2.5 ~ 6.4MPa.
4).Belofo ea serurubele se nang le khatello e phahameng-serurubele se nang le khatello ea lebitso PN10.0 ~ 80.0MPa.
Khatello e phahameng ka ho fetisisa ea valve ea serurubele e tšoana le phello e khutšoanyane ea nkho.Matla a metsi a itšetlehile ka poleiti e khutšoanyane ka ho fetisisa.Ho joalo le ka boleng bo phahameng ba khatello ea valve ea serurubele.
Joale re tseba joang tekanyo e phahameng ea khatello?
Mokhoa oa ho fumana tekanyo e phahameng ea khatello ea valve ea serurubele ke letoto la liteko tse etsoang ke moetsi ho lekola tšebetso ea valve le ho fumana tekanyo ea khatello ea eona.Liteko tsena li ka kenyelletsa:
1. Tlhahlobo ea lintho tse bonahalang
Etsa tlhahlobo ea metallographic ho likarolo tsa li-valve tsa serurubele ho netefatsa thepa ea thepa, le ho etsa liteko tsa mochini ho netefatsa hore valve ea serurubele e kopana le litekanyetso tse behiloeng tsa matla, ductility, joalo-joalo.
2. Teko ea Hydrostatic
Valofo e tlas'a khatello ea mokelikeli ho feta khatello ea eona e phahameng ka ho fetisisa (hangata e le mocheso o potolohileng kapa o phahameng) ho hlahloba botšepehi ba eona le ts'ebetso ea ho tiisa.
1).Tokisetso pele ho tlhahlobo
Pele o etsa tlhahlobo ea hydraulic valve valve, ho hlokahala hore ho etsoe litokisetso tse latelang:
a)Lekola bonnete ba lisebelisoa tsa tlhahlobo ho netefatsa hore tlhahlobo e ka etsoa ka polokeho le ka mokhoa o tloaelehileng.
b)Etsa bonnete ba hore valve ea serurubele e kentsoe ka nepo 'me ho hokahanngoa le mochine o lekanyang khatello ho tiisitsoe hantle.
c)Khetha pompo ea metsi e nang le khatello e nepahetseng ho netefatsa hore khatello ea teko le sekhahla sa phallo li finyella litlhoko.
d)Tlosa maloanlahla a ka amang liphetho tsa tlhahlobo nakong ea tlhahlobo le ho netefatsa hore tikoloho ea tlhahlobo e hloekile ebile e makhethe.
2).Mehato ea teko
a)Qala ka ho koala valve ho valve ea serurubele, ebe u bula pompo ea metsi, 'me butle-butle eketsa khatello ea metsi ho fihlela khatello ea teko.
b)Boloka khatello ea teko nako e itseng 'me u hlahlobe hore na ho na le ho lutla ho pota-potileng valve ea serurubele.Haeba ho na le leak, e hloka ho lokisoa ka nako.
c)Ka mor'a nako ea tlhahlobo, butle-butle fokotsa khatello ea metsi 'me u hloekise valve ea serurubele le mochine oa ho lekanya khatello ho qoba litšila tsa metsi ka mor'a tlhahlobo.
3).Mekhoa ea liteko
Haholo-holo ho na le mekhoa e latelang ea tlhahlobo ea hydraulic valve valve:
a)Mokhoa oa teko ea khatello e tsitsitseng: Emisa pompo ea metsi, boloka khatello ea teko bakeng sa lihora tse 1-2, 'me u shebe hore na ho na le ho lutla ho potoloha valve ea serurubele.
b)Mokhoa oa ho hlahloba khatello ea matla: Ha u ntse u boloka phallo ea teko le khatello, bula valve ea serurubele, sheba hore na valve e sebetsa ka mokhoa o tloaelehileng, 'me u hlahlobe hore na ho na le ho lutla ho pota-pota.
c)Teko ea khatello ea moea: Kenya khatello ea moea kapa ea khase ho valve ea serurubele ho etsisa maemo a ts'ebetso le ho lekola karabelo ea eona ho feto-fetoha ha khatello ho netefatsa ts'ebetso e tšepahalang tlasa maemo a matla.
d)Teko ea ho palama baesekele: Valofo ea serurubele e tsamaea ka libaesekele khafetsa lipakeng tsa maemo a bulehileng le a koetsoeng tlas'a maemo a fapaneng a khatello ho lekola ho tšoarella ha eona le botšepehi ba ho tiisa.
Ke hobane'ng ha u ka etsa qeto ea hore na valve ea serurubele e na le khatello e kae?
Ho khetholla tekanyo e phahameng ea khatello ho u lumella hore u khethe valve e loketseng ea serurubele bakeng sa kopo le ho netefatsa ts'ebetso e sireletsehileng ka har'a meeli e boletsoeng ea khatello.
1. Tšebelisano ea Kopo
Khetha valve ea serurubele e nang le tekanyo ea khatello e fetang khatello e phahameng ea ts'ebetso e ka 'nang ea etsahala tsamaisong ea liphaephe ho thibela ho tlala ha serurubele.
2. Ho nahanela mocheso
Nahana ka liphetoho tsa mocheso tsamaisong ea mokelikeli, eseng feela ka lebaka la ho atolosoa ha mocheso le ho fokotseha.Lithempereichara tse phahameng li tla baka keketseho ea khatello ea mokelikeli, 'me mocheso o phahameng o tla ama thepa ea valve le ho fokotsa matla a eona a ho sebetsana le khatello.
3. Tšireletso ea Khatello ea Khatello
Kenya lisebelisoa tse loketseng tsa ho imolla khatello kapa li-surgeon ho fokotsa ho phahama ha khatello le ho sireletsa valve ea serurubele ho li-spikes tsa tšohanyetso tse fetang matla a eona a lekantsoeng.
Ka kakaretso, khatello e phahameng ka ho fetisisa eo avalve ea serurubelee ka mamella ho khethoa ke moralo oa eona, thepa, sebopeho le mokhoa oa ho tiisa.Tekanyo e phahameng ea khatello ke parameter ea bohlokoa ho netefatsa ts'ebetso e bolokehileng le e sebetsang ea li-valve tsa serurubele.Ka ho utloisisa lintlha tse amang likhatello tsa khatello, hore na li ikemiselitse joang, le phello ea tsona ho khetho le tšebeliso ea li-valve tsa serurubele, valve e loketseng ea serurubele e ka khethoa ka nepo ho netefatsa polokeho le ts'ebetso ea valve ea serurubele nakong ea tšebeliso.
