MIBVUNZO INONYANYA KUBVUNZWA

Ndeipi nzira yekumanikidza yekuyedza yegedhi valve?

Gedhi igondohwe remusoro, uye mafambiro evhavha disc ari perpendicular kugwara remvura, uye vharafu inogona kungovhurwa zvizere uye yakavharwa zvizere, haigone kugadziridzwa uye throttle. Ivhavha yegedhi yakavharwa kuburikidza nechigaro chevhavha uye diski yevhavha, kazhinji chisimbiso chepamusoro chichakwira pamusoro pesimbi yesimbi kuti iwedzere kupikisa kupfeka, zvakadai sepamusoro pe1Cr13, STL6, simbi isina tsvina uye zvichingodaro.Disiki ine rigid disc uye elastic disc. Zvinoenderana nekusiyana kweiyo disc, mavharuvhu egedhi akakamurwa kuita akaomesesa gedhi mavharuvhu uye elastic gedhi mavharuvhu.

iyo nzira yekuedza yekumanikidza yevhavha yegedhi

Kutanga, diski yakavhurwa, kuitira kuti kumanikidzwa mukati mevhavha kusimuke kune kukosha kwakatarwa. Zvadaro, vhara gondohwe, pakarepo bvisa chivharo chegedhi, chengetedza kana pane kuputika pamativi maviri e diski, kana kuti zvakananga kupinda mukati mekuedza kune kukosha kwakatarwa pavhavha yevhavhavhavha, uye chengetedza chisimbiso kumativi ose e disc. Nzira iri pamusoro iyi inonzi pressure yepakati pekuedza. Iyi nzira haina kukodzera kuongororwa kwechisimbiso chevhavha yegedhi pasi pezita rokuti DN32mm.

Imwe nzira ndeyekuvhura dhisiki kuita kuti vhezheni yekuedza kukwira kune iyo yakataurwa kukosha; wobva wadzima dhisiki, vhura ndiro yebofu kune imwe mugumo, uye tarisa kubuda kwechisimbiso chiso. Wobva wadzokera kumashure, dzokorora bvunzo kusvika wakwanisa sepamusoro.

Muedzo wekuisa chisimbiso pakuzadza uye gasket yevhavha yepneumatic inofanira kuitwa pamberi pechisimbiso bvunzo ye disc.

Nheyo yekushanda yemagetsi actuator
Electric actuator musanganiswa weiyo actuator uye control valve mune otomatiki control system. Basa rayo mune otomatiki kudzora sisitimu ndeyekugamuchira chiratidzo kubva kune regulator, uye nechinzvimbo chayo uye hunhu mukuita pombi, kudzora kuyerera kwe process media kudzora maitiro ekugadzira mukati meiyo inodiwa renji.
Nzira yekuchengetedza uye kuchengetedza valve?
Kuti iite basa renguva refu rinoenderera mberi, zvinodikanwa kugara uchigadzirisa uye manejimendi akasimba emidziyo yese nemidziyo.Jinbin mavharuvhu zvakabatana nemidziyo iyi nemidziyo
Kutamba kuita kwayo kwekutonga kwezvikamu zvakakosha, saka,Jinbin mavharuvhuinofanirwa kutariswa yakazara kuchengetedza uye manejimendi dambudziko.
Jinbin valveMaintenance
Jinbin Mavharuvhu zvinhu zvakakosha zvinobatanidza zvishandiso izvi nemidziyo pamwe chete uye kutamba mashandiro avo ekutonga, uye nekudaro zvinofanirwa kufunga nezvekugadzirisa uye manejimendi nyaya.
 
Maintenance of thevharafumuhusungwa
Kutakurwa kwevhavha kupinda muimba yekuchengetera, muchengeti anofanira kunge ari panguva yemaitiro ekuchengetedza, izvo zvinobatsira pakuongorora uye kuchengetwa kwevhavha. Muchengeti anofanirwa kunyatsotarisa maitiro emuenzaniso wevhavha, kutarisa kutaridzika kwehutano hwevhavha, uye kubatsira vaongorori vevhavha pamberi pekuedzwa kwesimba rekuchengetedza uye kuvhara muedzo. Sangana nemaitiro ekugamuchirwa kwevhavha, inogona kubatwa kuitira kuchengetedza maitiro; kukundikana kunofanirawo kuchengetedzwa nemazvo, kuti kugadziriswe nemapazi akakodzera.
Paraibhurari yevhavha, kunyatsopukuta, kuchenesa valve mukufambisa kwemvura uye guruva tsvina, nyore kuita ngura pamusoro, tsinde, chisimbiso chepamusoro chinofanira kuputirwa nemucheka we anti-rust agent kana kuisa pepa re-anti- Rust pepa kuti richengetedzwe; iyo vharafu inopinza uye yekubuda migero kushandisa chivharo chepurasitiki kana bepa rewakisi kuti rivharwe, kuti usapinda tsvina.
Inventory inofanira kuitwa maererano nehukuru uye hukuru hwehurongwa, kubudiswa pamasherufu; mavharuvhu makuru anogona kubudiswa muimba yokuchengetera zvinhu pasi, maererano muenzaniso nokurondedzerwa Akaiswa zvidimbu. Ivhavha inofanira kuiswa yakatwasuka, kwete iyo flange yekuisa chisimbiso pamusoro pekubata pasi, asi isingabvumirwe kuungana pamwechete.
Kuti uchengetedze vheji iri mumamiriro ezvinhu akanaka, kunze kwekudiwa kwekuoma uye kwemhepo, yakachena uye yakachena yekuchengetedza, panofanira kunge kune seti yepamusoro, yesayenzi yekugadzirisa hurongwa hwekuchengetwa kwevhavha inofanira kugara ichiongororwa.
Nokuda kwekushandiswa kwenguva refu kwevhavha, kana kushandiswa kweasbestos kurongedza, inofanira kunge iri asbestos kutakura kubva kune tsamba yekutakura yakabviswa, kuitira kuti urege kudzivisa kuparara kwemakemikari emagetsi, kukuvadza kune stem.
Kupfuura zvigadziro zvekushandiswa kwerust inhibitors, lubricant, inofanira kugara ichitsiviwa kana kuwedzerwa.
Ndeipi misimboti yekushanda yevharuvhu yeshavishavi?

Kushanda kwakafanana neabhora vharafu, iyo inobvumira kukurumidza kuvhara. Butterfly mavharuvhuanowanzo kufarirwa nekuti anodhura zvishoma pane mamwe magadzirirwo evharuvhu, uye akareruka huremu saka anoda rubatsiro rushoma. Iyo disc yakaiswa pakati pepombi. Tsvimbo inopfuura nepa disc ichienda kune actuator iri kunze kwevharuvhu. Kutenderedza actuator inoshandura dhisiki ringaite parallel kana perpendicular kuyerera. Kusiyana nevhavha yebhora, disc inogara iripo mukati mekuyerera, saka inokonzera kudonhedzwa kwekumanikidzwa, kunyange kana yakazaruka.

Varuvhu yeshavishavi inobva kumhuri yemavharuvhu inonzi quarter-turn valves. Mukushanda, vharuvhu yakazaruka kana yakavharwa kana dhisiki ichitenderedzwa kota. “Butterfly” idhisiki resimbi rakaiswa patsvimbo. Kana vharuvhu yakavharwa, disc inoshandurwa kuitira kuti ivhare zvachose kubva panzira. Kana vharuvhu yakazaruka zvizere, dhisiki inotenderedzwa kota kutendeuka kuitira kuti inobvumira nzira inenge isina kuganhurirwa yemvura. Ivhavha inogonawo kuvhurwa zvishoma nezvishoma kuti iite throttle flow.

Kune marudzi akasiyana eshavishavi mavharuvhu, rimwe nerimwe rakachinjirwa kumanikidziro akasiyana uye kushandiswa kwakasiyana. Zero-offset butterfly valve, iyo inoshandisa kuchinjika kwerabha, ine yakaderera chiyero chekumanikidza. Iyo yepamusoro-inoshanda kaviri yekubvisa butterfly valve, inoshandiswa mune zvishoma-inodzvinyirira masisitimu, inobviswa kubva pakati pemutsara wedhisiki chigaro uye chisimbiso chemuviri (offset one), uye mutsara wepakati webore (offset maviri). Izvi zvinogadzira cam chiitiko panguva yekushanda kusimudza chigaro kunze kwechisimbiso zvichikonzera kukweshana kushoma pane inogadzirwa mu zero offset dhizaini uye inoderedza maitiro ayo ekupfeka. Ivharuvhu inonyatsokodzera masisitimu e-high-pressure ndiyo katatu offset butterfly valve. Muvharuvhu iyi disc seat yekubata axis inomiswa, iyo inoita kuti ibvise kutsvedza kusangana pakati pe disc nechigaro. Kana iri katatu offset mavharuvhu chigaro chinogadzirwa nesimbi kuitira kuti inogona kugadzirwa zvakadai sekuwana bubble tight shut-off paunosangana ne disc.

Sei Valve Yangu Iri Kudonha?

Mavharuvhu anogona kudonha nekuda kwezvikonzero zvakasiyana, kusanganisira:

  • The valve isisina kuvharwa zvizere(semuenzaniso, nekuda kwetsvina, marara, kana chimwe chipingamupinyi).
  • The valve iskukuvadzwa. Kukuvadza kune chigaro kana chisimbiso kunogona kukonzera kuvuza.
  • The valve ishaina kugadzirirwa kuvhara 100%. Mavharuvhu akagadzirirwa kunyatso kudzora panguva yekupuruzira anogona kunge asina kunaka pa/kudzima kugona.
  • Iyo valve ndiyosaizi isiriyozvepurojekiti.
Ndeupi ruzivo rwandinoda kuti ndinyatsokura uye ndisarudze valve?
Zvikamu zvitanhatu zveruzivo zvinodikanwa pakukura uye sarudza vharafu kana kumanikidza vharafu:

  1. Saizi yekubatanidza uye mhando
  2. Set pressure (psig)
  3. Tembiricha
  4. Back pressure
  5. Service
  6. Inodiwa kugona
