Valve seimwe yemidziyo yakakosha mukugadzirwa kwemaindasitiri, kubva pakusarudza kuenda kune kugadzirisa inogona kusangana nematambudziko mazhinji, apa Xiaobian akaunganidza mamwe matambudziko akajairika, ona kana ichigona kukubatsira?
1, Ndezvipi zvinhu zvitatu zvakakosha zvinofanirwa kutariswa pakusarudza actuator?
(1) Kubuda kweactuator kunofanira kunge kwakakura kudarika mutoro wevhavha, uye inofanira kufananidzwa zvinonzwisisika.
(2) Paunenge uchitarisa musanganiswa wakajairwa, zvinodikanwa kufunga kana iyo inobvumidzwa yekumanikidza musiyano inotsanangurwa nevhavha inosangana nezvinodiwa maitiro. Apo mutsauko wekumanikidzika wakakura, simba risina kuenzana pavhavha yevhavha rinofanira kuverengwa.
(3) Izvo zvinodiwa kuti utarise kana iyo yekupindura kumhanya kweiyo actuator inosangana nezvinodiwa zvekushanda kwemaitiro, kunyanya electric actuator.
2, Kuenzaniswa nepneumatic actuator, ndeapi maitiro uye mafomu ekubuda emagetsi actuator?
Iyo yemagetsi drive sosi isimba remagetsi, yakapusa uye yakanakira, ine yakakura thrust, torque uye kuoma. Asi chimiro chakaoma uye kuvimbika kwakashata. Inodhura kudarika pneumatic mudiki uye nepakati saizi. Inowanzo shandiswa muzviitiko zvisina gasi sosi kana yakasimba kuputika-chiratidzo uye murazvo-uchapupu.
Iyo yemagetsi actuator ine matatu ekubuda mafomu: angular sitiroko, yakatwasuka sitiroko uye yakawanda kutenderera.
3, Sei iyo yekucheka-kubvisa yekumanikidza musiyano wekona sitiroko vharafu yakakura?
Iyo yakakura yekucheka-yekuremerwa mutsauko wekona sitiroko vharafu imhaka yekuti simba rinokonzeresa rinogadzirwa nepakati pavharuvha core kana ndiro yevharuvhu ine diki torque pane inotenderera shaft, saka inogona kutakura yakakura kudzvanywa musiyano. Butterfly vharafu uye bhora vharafu ndiwo anonyanya kuzivikanwa ekona sitiroko mavharuvhu.
4, Ndeapi mavharuvhu anoda kuyerera kutungamira sarudzo? Nzira yekusarudza?
Kune imwechete seal control valves, yakadai sevhavha yechigaro chimwe chete, high pressure valve uye single seal sleeve valve pasina gomba rekuenzanisa, nzira yekuyerera inofanira kusarudzwa.
Kuyerera kuvhurika nekuvhara kuyerera kune zvakanakira uye nekuipa kwavo. Iyo inoyerera yakavhurika vharuvhu inoshanda zvakatsiga, asi yayo yekuzvichenesa kuita uye yekuisa chisimbiso kuita kwakashata, uye hupenyu hwayo hwesevhisi hupfupi; Ivhavha yakavharwa inoyerera ine hupenyu hurefu hwebasa, kuita kwakanaka kwekuzvichenesa uye kuita chisimbiso, asi kugadzikana kwakashata kana dhayamita yetsinde iri pasi pe spool dhayamita.
Single seat valve, diki yekuyerera vharafu uye imwechete seal sleeve valve inowanzoyerera, uye kuyerera kubva kunogona kusarudzwa kana scouring yakanyanya kana paine chinodiwa chekuzvichenesa. Iyo mbiri nzvimbo inokurumidza kuvhura inodzora vharafu ndeyekuyerera inosarudza yakavharwa mhando.
5, Pamusoro pevharuvhu yechigaro chimwe chete, vharafu yechigaro cheviri uye vharafu remaoko, ndeapi mamwe mavharuvhu ane basa rekutonga?
Diaphragm vharafu, butterfly valve, O-type bhora vharafu (kunyanya kuchekwa-kubvisa), V-mhando yebhora vharafu (hombe regulation reshiyo uye shear basa) uye eccentric rotary valve ese mavharuvhu ane regulation basa.
6, Sei kusarudzwa kuchikosha kupfuura kuverenga
Kuenzaniswa nekuverenga uye kusarudzwa, kusarudzwa kunonyanya kukosha uye kwakaoma. Nekuti kuverenga kunongova kwakapfava formula kuverenga, haibvi pakurongeka kweformula pachayo, asi nekurongeka kweiyo yakapihwa maitiro paramita.
Kusarudzwa kwemhando kunosanganisira zvakawanda zvemukati. Kusava nehanya kuduku kuchaita kuti kusarudzwa kwemhando dzisina kunaka, izvo zvisingangotungamiriri kuparara kwevashandi, zvinhu zvehupfumi uye mari, asi zvinotungamirira kune mamwe matambudziko ekushandisa, akadai sekuvimbika, hupenyu hwebasa uye hutano hwekushanda.
7, Sei isingagone kushandiswa kaviri chisimbiso vharafu sevhavha yekuvhara?
Kubatsira kwekaviri chigaro chevharuvhu yepakati ndiyo yesimba rekuenzanisa chimiro, ichibvumira hukuru hwekumanikidza musiyano, uye chakashata chayo ndechekuti nzvimbo mbiri dzekuisa chisimbiso hadzigone kusangana zvakanaka panguva imwe chete, zvichikonzera kudonha kukuru.
Kana ikashandiswa zvisirizvo uye nekumanikidzwa mumamiriro ekucheka, mhedzisiro yacho haina kunaka. Kunyangwe kana kuvandudzwa kwakawanda kwakaitwa kwairi (senge kaviri seal sleeve valve), haina kudiwa.
8, Nei vharafu yezvigaro zviviri iri nyore kubvongodza kana ichishanda nekuvhura kudiki?
Kune imwechete musimboti, kana yepakati ichiyerera yakavhurika, vharafu ine kugadzikana kwakanaka; Kana iyo yepakati ichiyerera yakavharwa, kugadzikana kwevhavha kwakashata. Ivhavhavha yezvigaro zviviri ine mavharuvhu maviri, iyo yezasi yevharuvhu iri mukuyerera yakavharwa chinzvimbo, uye yekumusoro vharafu core iri mukuyerera yakavhurika chinzvimbo.
Nenzira iyi, kana uchishanda mukuvhurika kudiki, iyo inoyerera yakavharwa spool iri nyore kukonzeresa kuzununguka kwevhavha, ndicho chikonzero nei vharafu yechigaro cheviri isingagone kushandiswa mukuvhura kudiki.
9, Ndeapi maitiro eakatwasuka kuburikidza nechigaro chimwe chekudzora vharafu? Inoshandiswa kupi?
(1) Kuburitsa kudiki, nekuti kune spool imwe chete, iri nyore kuve nechokwadi chekuisa chisimbiso. Iyo yakajairwa kubuda ndeye 0.01% kV, iyo inogona kushandiswa sevhavha yekuvharira mukuwedzera dhizaini.
(2) Musiyano unobvumidzwa wekumanikidza idiki uye kupinza kwakakura nekuda kwesimba risina kuenzana. Iyo valve △ P yeDN 100 inongova 120 kPa.
(3) Simba rekutenderera idiki. Iyo kV yeDN 100 inongova 120. Inowanzoshandiswa mumamiriro ezvinhu ekudonha kuduku uye kusiyana kuduku kwekudzvinyirira.
10, Ndeapi maitiro eakatwasuka kuburikidza maviri chigaro chekudzora vharafu? Inoshandiswa kupi?
(1) Musiyano unobvumidzwa wekumanikidza wakakura, nekuti unogona kurwisa masimba mazhinji asina kuenzana. Iyo valve △ P yeDN 100 ndeye 280 kPa.
(2) Huru yekutenderera simba. Iyo kV yeDN 100 i160.
(3) Kudonha kwacho kwakakura nekuti maviri mavharuvhu cores haagone kuvharwa panguva imwe chete. Muyero wekuyerera ndeye 0.1% kV, inova ka10 yevharuvhu yechigaro chimwe chete. Yakatwasuka kuburikidza nekaviri chigaro chekudzora vharafu inonyanya kushandiswa mukutsikirira mutsauko, zvinodikanwa zvekudonha hazvisi nguva dzakasimba.
.
Ivhavhavha yepakati peiyo yakatwasuka sitiroko vharafu iri vertical throttling, uku iyo yepakati ichiyerera ichipinda nekubuda yakachinjika. Iyo yekuyerera mugero yevharuvhu inofanira kutendeukira pasi, izvo zvinoita kuti nzira yekuyerera yevharuvhu ive yakaoma (senge inverted "s" chimiro). Nenzira iyi, kune nzvimbo dzakawanda dzakafa, dzinopa nzvimbo yekunaya kwepakati. Mukufamba kwenguva, zvinokonzeresa blockage.
Iro throttling direction ye angle stroke valve ndiyo yakatwasuka. Iyo svikiro inoyerera ichipinda nekubuda yakachinjika, zviri nyore kubvisa svikiro. Panguva imwecheteyo, nzira yekuyerera iri nyore, uye nzvimbo yekunaya kwepakati idiki zvakare, saka iyo angle stroke valve ine yakanaka anti blocking performance.
12, Mumamiriro ezvinhu akaita sei mavharuvhu anomira anoda kushandiswa?
(1) Panyaya yekukweshana kukuru uye kunyatsomira. Semuyenzaniso, tembiricha yakakwirira uye yakaderera tembiricha kudzora vharafu kana kudzora vharafu pamwe flexible graphite kurongedza;
(2) Slow process inoda kuvandudza kumhanya kwekupindura kwevhavhavha yekudzora. Semuenzaniso, tembiricha, chiyero chemvura, kuongororwa uye mamwe ma parameter eiyo regulation system.
(3) Izvo zvinodiwa kuvandudza simba rekubuda uye simba rekucheka reiyo actuator. Semuenzaniso, imwe chigaro chevhavha ine DN ≥ 25 uye kaviri chigaro chevhavha neDN > 100. Apo kudzvinyirira kunodonha pamagumo ose evhavha △ P (＞ 1MPa kana kuti inlet pressure P1 ＞ 10MPa).
(4) Mukushanda kwekupatsanurwa kwekugadzirisa hurongwa uye valve yekudzora, dzimwe nguva inofanirwa kuchinja maitiro emhepo yekuzarura uye kuvhara kwemhepo (5) Zvakakosha kushandura maitiro ekuyerera kwevhavha yekudzora.
