Boiler Chengetedza Valve ndechimwe chezvakakosha kuchengetedza zvishongedzo kuti ive nechokwadi chekushanda kwakachengeteka kwebhailer.Kunyangwe ichigona kuvhurwa nemazvo uye nekuvimbika zvakakosha zvikuru kuchengetedza kushanda kwakachengeteka kwebhailer.

Sevhavha ine basa rakakosha rekudzivirira, vharavhavhavha yekudzivirira inoshandiswa zvakanyanya mumidziyo yakasiyana-siyana yekumanikidza uye piping system, kana iyo yekumanikidza mudziyo system inosvika kumucheto wepamusoro weiyo yakatarwa yekumanikidza inotakura kukosha, iyo yekumanikidza mudziyo inogona kuvhurwa otomatiki neinduction, uye yakawandisa. svikiro inogona kubudiswa kunze kwekumanikidzwa kwemudziyo system, uye inogona kuvharwa otomatiki mushure mekuburitswa, nekudaro kuve nechokwadi chekuti ngarava yekumanikidza inogona kushandiswa mukati meyakachengeteka uye yakavimbika kumanikidza inobvumidzwa, kudzivirira njodzi huru dzekuchengetedza.Kushanda kwakajairwa kwevhavhavhavha yekuchengetedza hakungone chekuita neyakajairwa yakachengeteka kushandiswa kwemidziyo yekumanikidza senge boilers, asiwo yakanangana nekuchengetedza kwehupenyu hwevanhu uye zvivakwa.Naizvozvo, kutarisisa kukuru kunofanirwa kubhadharwa kune zvakajairika kukundikana kweBoiler Safety Valve, uye kuibvisa panguva yakakodzera.

1. Safety Valve Leak

Kudonha kwevhavha ndeimwe yeanowanzo zvikanganiso zveBoiler Safety Valve.Iyo inonyanya kureva kudonha pakati pevharuvhu disc uye chigaro chevharuvhu pasi pesimba rekushanda rakajairwa.

Zvikonzero zvekutadza uye mhinduro dzadzo:

1) Tsvina inowira panzvimbo yekuisa chisimbiso.Simudza wrench inogona kushandiswa kuvhura vharuvhu kakawanda, tsvina yakashambidzwa.

2) Chisimbiso 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.

3) Nekuda kweIsina Kufanira Gungano kana pombi mutoro uye zvimwe zvikonzero, ita zvikamu zvekukuvadza kwe concentricity.Kuwedzera mitoro yepombi inofanira kubatanidzwazve kana kubviswa;

4) Vhidhiyo yekuvhurwa kwevhavha iri padyo zvakanyanya kune yakajairwa dhizaini yekumanikidza, zvekuti yekuisa chisimbiso yakadzikira pane kudzvanywa.Kana vharuvhu iri pasi pekudengenyeka kana kwepakati kudzvinyirirwa kushanduka, inowanzoita kudonha.Iyo yekuvhura kudzvanywa kunofanirwa kugadziridzwa zvinoenderana nemidziyo simba mamiriro.

5) Chitubu chakasununguka chinoderedza kudzvanywa kwekuisa uye chinoita kuti vharafu ibude.Inogona kuva nekuda kwekushisa kwepamusoro kana kuora uye zvimwe zvikonzero, zvinofanira kutorwa kushandura chitubu, kana kunyange kushandura valve uye mamwe matanho.Kana iyo yakakonzerwa nemutemo usina kukodzera, inongoda kuomesa screw yekugadzirisa zvakanaka.

2. Kuderera Kudzorera kudzvinyirira kwevhavha yekuyamura

Zvikonzero zvekutadza uye mhinduro dzadzo:

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, iyo yepakati inoenderera mberi. kuburitsa, kuzunguza Relief Valve Body, kana impulse relief valve pamberi uye mushure mesimba nekuda kweiyo huru yekuyamura valve medium discharge haina kukwana kuti irambe ichiwedzera, saka chiutsi chiri mu pulse chubhu pamwe nedhiramu gasi musoro unoramba uchiyerera. vharafu chiito.

Kune rimwe divi nekuda kwerudzi urwu rweImpulse safety valve action impulse safety valve sealing surface.Kurongeka kwayo kuti iite kinetic pressure zone, spool ichasimudzwa, kuitira kuti iyo impulse kuchengetedza vharafu irambe ichibuda, iyo yakakura kubuda kwemhepo, basa reSpool pakuchengetedza kwekukanda pane yakakura, iyo Impulse chengetedzo. vharafu zvichava nyore kudzokera kuchigaro.Panguva ino, nzira yekubvisa kukanganisa ndeyekudzima throttle valve, kuitira kuti kuyerera kwevhavha yekupupurika kuderedza kudzvinyirira mukinetic simba rekumanikidza zone, kuitira kuti iyo impulse relief valve idzokere pachigaro.Chinhu chechipiri chinokonzera kuderedzwa kwekudzoka kwakaderera ndechokuti chibvumirano chakakodzera pakati pe spool uye sleeve yemutungamiri haina kukodzera, uye chibvumirano chakakodzera chiduku, kunonoka Kudzoka Nguva, nzira yekubvisa kukundikana uku ndeyekunyatsoongorora ukuru hwe. spool inotungamirawo zvimedu zvemaoko, ine diki clearance, dzikisa disc chivharo zvakananga kana disc stop valve cap dhayamita kana kuwedzera disc uye inotungamira sleeve radial clearance, kuwedzera nzvimbo yekutenderera kwechikamu, kuitira kuti kuyerera kwemhepo kurege kutsauswa kana dzvinyiriro yemunharaunda kuti iite yakakwirira kinetic pressure zone.

3. Body Joint Leakage

Valve yemuviri yakabatana pamusoro kuvuza inonyanya kureva iyo yepamusoro uye yakaderera vharafu muviri wejoinhi pamusoro pemvura inodonha chiitiko.

Zvikonzero zvekutadza uye mhinduro dzadzo:

Imwe inzvimbo yakabatana yebhaudhi yakasimba simba haina kukwana kana kusimba chidimbu, zvichikonzera kusabatana kwechisimbiso chakashata.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.

Chechipiri, iyo vharafu yemuviri yakabatana pamusoro pezino seal gasket haina kusangana nechiyero.Semuyenzaniso, diki groove mu radial gwara rezino seal gasket, kushata parallelism, zino rakanyanya kupinza kana kutsetseka uye kumwe kukanganisa kunokonzeresa kukundikana kwechisimbiso.Izvi zvinoita kuti vheji yemuviri wejoin idere.Mukuchengetedza kwemhando yezvigadziriso, kushandiswa kweyakajairwa mazino-akaita gasket kunogona kudzivirira chiitiko ichi.

Chetatu, iyo vharafu muviri wejoinhi ndege yakashata zvakanyanya kana nekuomarara kusachena cushion chisimbiso kutadza.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. Kunonoka Kudzoka kwevhavha yekuyamura

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

Zvikonzero zvekutadza uye mhinduro dzadzo:

Pane zvikonzero zvikuru zviviri zvekukundikana uku.Kune rimwe divi, kuvuza kwePiston Chamber yevharuvhu yekuyamura yakakura.Kunyange zvazvo vharafu yekuyamura yadzokera kuchigaro chayo, mhepo yemhepo mupombi uye muPiston Chamber ichiri yakakwirira, uye simba rekusundira piston pasi richiri rakakura, izvi zvinokonzera kuti vharafu huru yekuyamura idzokere pachigaro. zvishoma nezvishoma.Nzira yekubvisa dambudziko rerudzi urwu inonyanya kugadziriswa nekuvhura iyo throttle valve yakafara uye nekukudza throttle hole dhayamita.Zvese zviri zviviri kuvhurwa kwevhavhavha yekuvhuvhuta uye kuwedzera kwegomba rekufemesa kunoita kuti chiutsi chasara mu pulse chubhu chibude nekukasira, nekudaro, kudzvanywa muPiston kunoderedzwa, uye simba rekusundira rinoshanda paPiston richikwira nekudzika. nokukurumidza kuderedzwa.Iyo yevharuvhu yepakati inokurumidza kudzoserwa kuchigaro pasi pekusimudza kwepamusoro kwemhepo yemhepo mumusoro uye simba rekukwevera kumusoro revharuvha huru yekuchengetedza chitubu pachayo.Kune rumwe rutivi, kukakavara pakati pezvikamu zvinofamba uye zvikamu zvekugadzirisa zvevhavha huru yekuchengetedza kuchaita kuti vheji huru yekudzivirira idzoke kuchigaro zvishoma nezvishoma, mhinduro yedambudziko iri ndeyekuenderana nevhavha huru yekuyamura inofamba zvikamu uye zvikamu zvakagadziriswa. mukati meiyo standard clearance console range.

5. Safety Valve Chatter

Iyo vibration phenomenon yevhavhavha yekuchengetedza mukuita kwekuburitsa inonzi chatter yevhavhavhavha.Iyo chatter phenomenon inokonzeresa kuneta kwesimbi zviri nyore, izvo zvinodzikisira mashandiro emagetsi evhavhavhavha uye zvinokonzeresa dambudziko rakavanzika remidziyo.

Zvikonzero zvekutadza uye mhinduro dzadzo:

Zvinonyanya kukonzera flutter ndezvizvi: Kune rumwe rutivi, chivharo chinoshandiswa zvisina kunaka, simba rekubuda kwevhavha rakanyanya kukura, nzira yekubvisa ndeyokuti chiyero chekubuda kwevhavha inofanira kushandiswa sepedyo sezvinobvira kune kubudiswa kunodiwa kwemidziyo.Kune rimwe divi, nekuti dhayamita yepombi inopinza idiki, idiki pane dhayamita inopinza yevhavha, kana kushorwa kwepombi inopinza yakakura kwazvo, nzira yekubvisa ndeye kana vharafu yakaiswa, dhayamita yemukati. yepipe inopinza haifaniri kunge iri pasi peiyo inlet dhayamita yevhavha kana kushorwa kwepombi inopinza inofanira kuderedzwa, izvi zvinogona kugadziriswa nekuderedza kushorwa kwemutsara wekubuda.
