Isebenza Njani Ivalve yeBhola?

Jonga umfanekiso oMkhulu
Iivalve zebhola zezinye zeentlobo zevalve ezisetyenziswa kakhulu kumashishini ahlukeneyo.Imfuno yevalve yebhola isakhula.Ngaba uye wakha wazibuza ukuba i-valve yebhola yenza njani impembelelo kwizicelo zakho.Kweli nqaku, uya kufunda malunga namacandelo aqhelekileyo e-valve yebhola kunye nemisebenzi yabo.Ngaphezu koko, siza kukubonisa indlela ivalve yebhola esebenza ngayo ukukunceda ukuba uyiqonde ngcono phambi kokuba ube nesinye sezicelo zakho.

Yintoni iValve yeBhola?

Njengoko igama layo libonisa, i-valve yebhola ine-disc efana nebhola esebenza njengesithintelo xa ivalve ivaliwe.Iinkampani ezenza iivalvu zebhola zihlala ziyila ivalve yebhola ukuba ibeyivalve yekota kodwa inokuba luhlobo olujikelezayo xa ilawula okanye iphambukisa ukuhamba kwemithombo yeendaba.

Iivalvu zebhola zihlala zisetyenziswa kwizicelo ezifuna ukutywinwa okuqinileyo.Ziyaziwa ngokuba ne-low-pressure drops.Ukujika kwayo kwe-90-degree kwenza kube lula ukusebenza nokuba imidiya inomthamo ophezulu, uxinzelelo okanye ubushushu.Banoqoqosho kakhulu ngenxa yobomi babo benkonzo obude.

Iivalvu zebhola zilungele iigesi okanye ulwelo olunamasuntswana amancinci.Ezi valves azisebenzi kakuhle kunye nodaka njengoko ezi zamva zizonakalisa ngokulula izitulo ezithambileyo ze-elastomeric.Ngelixa benamandla okuginya, iivalvu zebhola azisetyenziswa ngolo hlobo kuba ukukhuhlana okuvela kwi-throttling kunokonakalisa izihlalo nazo.

Iinxalenye zeValve yeBhola

Kukho iindidi ezininzi zeevalvu zebhola, njengevalve yebhola yendlela ezi-3 kunye neevalvu zebhola kwizinto ezahlukeneyo.Enyanisweni, indlela yokusebenza yevalve yebhola ye-3 yahlukile kwivalve yebhola eqhelekileyo.Zininzi iindlela zokuhlela iivalvu.Nokuba kunjalo, kukho amacandelo asixhenxe evalvu eqhelekileyo kuzo zonke iivalvu.

Umzimba

Umzimba sisakhelo sevalve yebhola iphela.Isebenza njengesithintelo kumthwalo woxinzelelo oluvela kumajelo eendaba ngoko kungabikho ukutshintshwa koxinzelelo kwimibhobho.Igcina onke amacandelo kunye.Umzimba uqhagamshelwe kwimibhobho ngokudityaniswa kwemisonto, ebotiweyo okanye edityanisiweyo.Iivalvu zebhola zinokuhlelwa ngokohlobo lomzimba, odla ngokuphoswa okanye uxonxiwe.

Isiqu

Ukuvulwa okanye ukuvala i-valve kunikezelwa ngesiqu.Oku kukwayinto edibanisa i-disc yebhola kwi-lever, i-handle okanye i-actuator.Isiqu seso sijikelezisa idiski yebhola ukuyivula okanye ukuyivala.

Ukupakisha

Le yigasket enceda ukutywina ibhonethi kunye nesiqu.Imiba emininzi iyenzeka kule ndawo ngoko ke ukufakela okufanelekileyo kubalulekile.Ukukhululeka kakhulu, ukuvuza kwenzeka.Ukuqiniswa kakhulu, ukuhamba kwesiqu kuthintelwe.

Ibhonethi

Ibhonethi sisigqubuthelo sokuvuleka kwevalvu.Oku kusebenza njengomqobo wesibini woxinzelelo.Ibhonethi yiyo ebamba onke amalungu angaphakathi kunye emva kokuba efakwe ngaphakathi kumzimba wevalvu.Ihlala yenziwe ngesixhobo esifanayo nomzimba wevalvu, ibhonethi inokuthi yenziwe ngenkohliso okanye iphoswe.

Ibhola

Le yidiski yevalve yebhola.Ukuba ngumda wesithathu obaluleke kakhulu woxinzelelo, uxinzelelo lweendaba lusebenza ngokuchasene ne-disc xa ikwindawo evaliweyo.Iidiski zebhola zihlala zenziwe ngentsimbi ekhandiweyo okanye nayiphi na into ehlala ixesha elide.Idiski yebhola inokunqunyanyiswa njengakwimeko yevalvu yebhola edadayo, okanye inokuxhonywa njengaleyo yevalve yebhola efakwe kwi-trunnion.

Isihlalo

Ngamanye amaxesha kuthiwa ngamakhonkco etywina, kulapho idiski yebhola iphumla khona.Ngokuxhomekeke kuyilo lwediski yebhola, isihlalo sifakwe okanye sifakwe kwibhola.

I-Actuator

I-Actuator zizixhobo ezenza ukujikeleza okufunekayo kwivalve yebhola ukuvula idiski.Amaxesha amaninzi, ezi ziba nomthombo wamandla.Ezinye ii-actuator ziyakwazi ukulawulwa kude ukuze iivalvu zisasebenza nokuba zibekwe kwindawo ezikude okanye kunzima ukufikelela kuzo.

Ii-Actuator zinokuza njengamavili ezandla kwiivalvu zebhola eziqhutywa ngesandla.Ezinye iintlobo zee-actuator ziquka iintlobo ze-solenoid, iintlobo ze-pneumatic, iintlobo ze-hydraulic, kunye nezixhobo.

Isebenza Njani Ivalve yeBhola?

Ngokuqhelekileyo, indlela yokusebenza kwevalve yebhola isebenza ngolu hlobo.Nokuba iqhutywa ngesandla okanye i-actuator, amandla athile ahambisa i-lever okanye isiphatho ukuya kwikota yokujika ukuvula ivalve.La mandla adluliselwa kwisiqu, ehambisa i-disc ukuba ivule.

I-disc yebhola iyajika kwaye icala layo elinomngxuma lijongene nokuhamba kweendaba.Ngeli xesha, i-lever ikwi-perpendicular position kunye ne-port kwi-parallel ngokumalunga nokuhamba kweendaba.Kukho indawo yokumisa kufutshane nomdibaniso phakathi kwesiqu kunye nebhonethi ukuvumela kuphela ukujika kwekota.

Ukuvala ivalve, i-lever ibuyela emva kwikota yokujika.Isiqu siyashukuma sijike idiski yebhola kwelinye icala, sivalela ukuhamba kwemidiya.I-lever ikwindawo ehambelanayo kunye ne-port, perpendicular.

Nangona kunjalo, qaphela ukuba kukho iintlobo ezintathu zeentshukumo zediski yebhola.Nganye kwezi inemisebenzi eyahlukeneyo yokusebenza.

Ivalve yebhola edadayo inediski yayo yebhola exhonywe kwisiqu.Akukho nkxaso kwindawo esezantsi yebhola ukuze idiskhi yebhola ngokuyinxenye ixhomekeke kuxinzelelo lwangaphakathi kwiivalvu zebhola eziqinileyo zaziwa ngayo.
Njengoko ivalve ivala, uxinzelelo lwelayini olunyukayo olusuka kumajelo eendaba lutyhalela ibhola kwisihlalo esisezantsi somlambo.Oku kubonelela ngokuqina kwevalve eqinisekileyo, yongeza kwinto yokutywina kwayo.Isihlalo esisezantsi soyilo lwevalve yebhola edadayo sithwala umthwalo woxinzelelo lwangaphakathi xa ivalve ivaliwe.

Olunye uhlobo loyilo lwediskhi yebhola yivalve yebhola efakwe kwi-trunnion.Le ineseti yeetrani emazantsi ediski yebhola, nto leyo eyenza idiskhi yebhola imile.Ezi trunnions zifunxa amandla kumthwalo woxinzelelo xa ivalve ivala ukuze kubekho ukukhuhlana okuncinci phakathi kwediski yebhola kunye nesihlalo.Uxinzelelo lokutywina lwenziwa kumazibuko aphezulu kunye nasezantsi.

Xa ivalve ivala, izihlalo ezigcwele intwasahlobo zihamba ngokuchasene nebhola ejikeleza kuphela kwi-axis yayo.Ezi mithombo zityhala isitulo ngokuqinileyo ebholeni.Iintlobo zebhola ezifakwe kwi-Trunnion zifanelekile kwizicelo ezingadingi uxinzelelo oluphezulu ukuhambisa ibhola kwisihlalo esisezantsi.

Okokugqibela, ivalve yebhola enyukayo isebenzisa indlela yokuthambeka kunye nokujika.Idiskhi yebhola ijikela kwisihlalo xa ivalve ivala.Xa ivula, i-disc ijika ukuze izisuse esihlalweni kwaye ivumele ukuhamba kweendaba.
