Sevhavha ine basa rakakosha rekudzivirira,vharafu vharafuinoshandiswa zvakanyanya mumidziyo yakasiyana-siyana yekumanikidza uye pombi masisitimu, ayo anogona kuvhurika otomatiki kana sisitimu yasvika kumucheto wepamusoro weiyo yakatemerwa kutakura kukosha Bvisa iyo yakawandisa yepakati kunze kwehurongwa, uye mushure mekubuda kunogona kuvharwa otomatiki kuti uve nechokwadi chekuti Pressure mudziyo inogona kuve yakachengeteka, yakavimbika kumanikidza inobvumidzwa kushanda mukati mechikamu kudzivirira njodzi huru dzekuchengetedza.

Sekugadzira vharuvhu yekuchengetedza, COVNA yakazvipira kukubatsira iwe kusarudza nekugadzira vharuvhu yekuchengetedza yaunoda.Tibvunze isu kune yemahara valve mhinduro nemutengo wakanakisa.

● Size Range: DN20 kusvika DN400

● Max.Kudzvinyirira: 60 bar.Kana iwe uchida kudzvinyirira kwakakwirira, tapota taura nesu.

● Tembiricha: -29 kusvika 425℃

● Zvinhu Zvingasarudzwa: CF8, CF8M kana bhuronzi

● Kubatanidza: Yakapetwa kana kuti yakarukwa

● Masvikiro akakodzera: Steam, mhepo, zvichingodaro.

Kushanda kwakajairwa kwevhavhavhavha yekuchengetedza haina hukama chete neyakajairwa yakachengeteka kushandiswa kwemidziyo yekumanikidza senge boilers asiwo yakanangana nekuchengetedzeka kwehupenyu hwevanhu uye zvivakwa.Naizvozvo, kutarisisa kukuru kunofanirwa kubhadharwa kune zvakajairwa kutadza kweBoiler Safety Valve Uye kuibvisa panguva yakakodzera.

1. The Safety Valve Is Leaking

Kudonha kwevhavha ndeimwe yeanowanzo zvikanganiso zvevhavha yekuchengetedza vharafu.Iyo inonyanya kureva kuvuza pakati pevharuvhu disc uye chigaro chevharuvhu pasi pesimba rekushanda rakajairwa.

Zvikonzero zvekutadza uye mhinduro dzadzo:

1.1Tsvina inowira pamusoro pekuvhara.Shandisa chipanera chekusimudza kuvhura vharuvhu kakawanda kuti ubvise tsvina.

1.2Namadza kukuvara kwepamusoro.Maererano nehuwandu hwekukuvadza, nzira yekukuya kana kugaya mushure mekutendeuka inofanira kushandiswa kugadzirisa.Mushure mekugadzirisa kunofanirwa kuve nechokwadi chekuisa chisimbiso chepamusoro kutsetseka, kutsvedza kwayo hakufanirwe kunge kuri pasi pe10.

1.3Pamusana pekusangana kusina kukodzera kana mutoro wepombi, iyo concentricity yezvikamu inoparadzwa.Mimwe mitoro yepombi ichabatanidzwazve kana kusabatanidzwa.

1.4Iyo yekuvhura kudzvanywa kwevhavha iri padhuze zvakanyanya neyakajairwa kumanikidza kwemidziyo, kuitira kuti chisimbiso chepamusoro chakaderera pane kudzvanywa.Kana vharuvhu iri pasi pekudengenyeka kana kwepakati kudzvinyirirwa kushanduka, inowanzoita kudonha.Kudzvanywa kwekuvhura kunofanirwa kugadziridzwa zvinoenderana nemamiriro esimba emidziyo.

1.5Loose Spring Inoderedza kuseta kudzvanywa uye inokonzeresa kuvuza kwevhavha.Inogona Kuve nekuda kwekushisa kwepamusoro kana kuora uye zvimwe zvikonzero, inofanira kutorwa kushandura chitubu, kana kutoshandura vharafu uye mamwe matanho.Kana iyo yakakonzerwa nemutemo usina kukodzera, screwing screw inogona kusimbiswa zvakanaka.

2. Yakaderera Dzorera Dzvinyiriro Of Safety Valve

Chikonzero 1:Low Return pressure ichaita kuti nhamba huru yepakati ibude nekufamba kwenguva, zvichikonzera kurasikirwa kwesimba kusingakoshi.Chikonzero ndechekuti spring pulse relief valve pahuwandu hwemhepo inoyerera, iyi fomu yepulse relief valve kuvhura, yepakati inoramba ichibuda, vibration relief valve body, kana impulse relief valve pamberi uye shure kwesimba nekuda kweiyo huru. kuburitsa vharafu yepakati haina kukwana kuti irambe ichiwedzera, saka chiutsi chiri mupombo chubhu padivi pedhiramu gasi musoro chinoramba chichiyerera chichiita chekuyamura vharafu.

Kune rimwe divi nekuda kwerudzi urwu rwekumanikidza kuchengetedza vharafu chiito impulse kuchengetedza vharafu sealing pamusoro.Kurongeka kwayo kuti iite kinetic pressure zone, spool ichasimudzwa, kuitira kuti iyo impulse safety valve irambe ichibuda, iyo yakakura kubuda kwemhepo, basa re spool pakuchengetedzwa kwekusundirwa pane yakakura, kuchengetedzwa kwemhepo. vharafu zvichava nyore kudzokera kuchigaro.

Solution 1:Panguva ino, nzira yekubvisa kukanganisa ndeyekuvhara iyo throttle valve diki, kuitira kuti kuyerera kwepakati kunze kweiyo impulse relief valve kuderedza kudzvanywa mukinetic energy pressure zone, kuitira kuti impulse relief valve idzokere ku chigaro.

Chikonzero 2:Chinhu chechipiri chinokonzera kuderedzwa kwekudzoka kwakaderera ndechokuti kutenderwa kwakakodzera pakati pe spool uye sleeve yemutungamiri haina kukodzera, uye kubvumirwa kwekodzero idiki kunonoka kudzoka nguva.

Solution 2:Nzira yekubvisa kukundikana uku ndeyekunyatsotarisa saizi ye spool zvakare tungamira sleeve zvikamu, ine gap iri diki, kuderedza disc chivharo zvakananga kana disc stop valve cap dhayamita kana kuwedzera disc uye kutungamira sleeve radial gap, kuwedzera. nzvimbo yekutenderera kwechikamu, kuitira kuti kuyerera kweutsi kurege kutsauswa kana kudzvanywa kwenzvimbo kuumba yakakwirira kinetic pressure zone.

3. Body Joint Leakage

Iyo valve body joint surface leakage inonyanya kureva iyo yepamusoro uye yezasi vharafu muviri wejoin surface leakage phenomenon.

Zvikonzero zvekutadza uye mhinduro dzadzo:

Chikonzero 1:Imwe inzvimbo yakabatana yebhaudhi yakasimba simba haina kukwana kana kusimba chidimbu, zvichikonzera kusabatana kwechisimbiso chakashata.
Solution 1:Nzira yekubvisa ndeyekugadzirisa simba rekusimbisa bhaudhi, mubhaudhi rakasungwa rinofanira kubatwa maererano ne diagonal tightening nzira, zviri nani kuyera kumativi ose akasimba side clearance, bhaudhi yakasimba kuti irege kufamba kusvika ikozvino, uye ita. kubatana kwepamusoro pekuchenesa kwenzvimbo dzese kunoenderana.

Chikonzero 2:Chechipiri, iyo vharafu yemuviri yakabatana pamusoro pezino seal gasket haina kusangana nechiyero.Izvi zvinoita kuti vheji yemuviri wejoin idere.
Solution 2:Mukuchengetedza kwemhando yezvigadziriso, kushandiswa kweyakajairwa mazino-akaita gasket kunogona kudzivirira chiitiko ichi.

Chikonzero 3:Chekupedzisira, ivharuvhu yemuviri wakabatana ndege yakashata zvakanyanya kana nekuomarara kusachena cushion chisimbiso.
Mhinduro 3:Kubviswa kwekudonha kwepamusoro pemuviri nekuda kwekusadzikama kwemuviri wepamusoro ndeyekubvisa vharafu uye kukuyazve iyo yakabatana kusvika yasangana nemhando yepamusoro.Kana chisimbiso chikakundikana nekuda kwekusachena kurongedza, nyatsochenesa nzvimbo yakabatana kuti urege kusvibiswa kuwira mumusangano wevhavha.

4. Relief Valve Yakanonoka Kudzoka

Iko kushanda kukuru kwevhavha yekukurudzira mushure mekudzoka kwevhavha huru yekuyamura kunonoka kudzoka nguva yakakura zvikuru.

Zvikonzero zvekutadza uye mhinduro dzadzo:

Chikonzero 1:Kune rumwe rutivi, kuvuza kwekamuri yepiston yevharuvhu yekuyamura yakakura.
Solution 1:Nzira yekubvisa dambudziko rerudzi urwu inonyanya kugadziriswa nekuvhura iyo throttle valve yakafara uye nekukudza throttle hole dhayamita.

Chikonzero 2:Kune rumwe rutivi, kukakavara pakati pezvikamu zvinofamba uye zvikamu zvekugadzirisa zvevhavha huru yekudzivirira kuchaita kuti guru guru rekuchengetedza ridzoke kuchigaro zvishoma nezvishoma.
Solution 2:Mhinduro yedambudziko iri ndeyekukodzera iyo huru yekuyamura valve inofambisa zvikamu uye yakagadziriswa zvikamu mukati meiyo yakajairwa clearance console renji.

5. Relief Valve Chatter

Iyo vibration phenomenon yevhavhavha yekuchengetedza mukuita kwekuburitsa inonzi chatter yevhavhavhavha.Iyo chatter phenomenon inokonzeresa kuneta kwesimbi nyore, iyo inoderedza mashandiro emuchina weSafety Valve uye inokonzeresa dambudziko rakavanzika remidziyo.

Zvikonzero zvekutadza uye mhinduro dzadzo:

Chikonzero 1:Kune rumwe rutivi, chivharo chinoshandiswa zvisina kunaka, simba rekubuda revhavha yakakura zvikuru.
Solution 1:Nzira yekubvisa ndeyokuti iyo yakatemerwa kubuda kwevhavha inofanira kushandiswa sepedyo sezvinobvira kune kudiwa kunodiwa kwemichina.

Chikonzero 2:Kune rumwe rutivi, nokuti dhayamita yepombi inopinza iduku zvikuru, iduku kudarika dhayamita inopinza yevhavha, kana kuramba kwepombi inopinza yakakura zvikuru.
Solution 2:Iyo nzira yekubvisa iyo iyo valve yakaiswa, mukati memukati wepipe inopinza haifanirwe kunge iri pasi peiyo inlet dhayamita yevhavha kana kushorwa kweiyo inlet pombi kunofanira kuderedzwa Izvi zvinogona kugadziriswa nekuderedza kushorwa kwekubuda. line.

Chero chipi nechipi chinodiwa kana dambudziko revhavhavha yekuchengeteka, tapota taura nesu uye isu tichafara kukubatsira kuigadzirisa.
