Matanho ekudzivirira paunenge uchiisa mavharuvhu Kugara kushanda kwefluorine lined anticorrosive valves

 
Kana iyo valve yakaiswa, mushandisi haafaniri kungonzwisisa nzira yayo yekuisa, nokuti valve inoiswa apo kudzivirirwa kunokoshawo. Kana iwe usingateereri panguva yekuiswa, zviri nyore kukonzera kukanganisa kana kuputika kwevhavha, izvo zvichakonzera dambudziko rakawanda. Saka sei kudzivirira kana kuisa valve? Iyo inotevera Xiaobian ichanyatso kusuma matanho ekudzivirira ekuiswa kwevhavha.
Tarisa kudzivirira kwevhavha
KUTI UDZIVIRIRE kuputika kwevhavha yekuongorora kana kudzoka kwevezvenhau mushure mekukundikana, zvichikonzera kuderera kwehutano hwechigadzirwa, njodzi nemimwe migumisiro yakashata, imwe kana maviri mavharuvhu ekucheka akaiswa pamberi uye shure kwevhavha yekuongorora. Kana mavharuvhu maviri ekuvhara akapiwa, cheki chevhavha inogona kubviswa nyore nyore kushanda.
Zvivako zvekuchengetedza vharafu
Kuisa nzira isati yasvika uye mushure mejenera usaise vheji yekuparadzanisa, chete mumamiriro ega ega, inogona kushandiswa. Kana simba repakati riine zvimedu zvakasimba, zvinokanganisa valve yekuchengetedza haigoni kuvharwa mushure mokusimuka, kuisa mutobvu-yakavharwa gedhivhavha isati yasvika uye shure kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhatipitiswe,gedhi regedhi rinofanira kunge riri munzvimbo yakazaruka zvizere,vhavha yegedhi. uye vharafu yekuchengetedza yakanyatsogadzirirwa neDN20 yekuongorora valve kumhepo.
Kana kuzorora kwewakisi uye mamwe midhiya patembiricha yekamuri yenzvimbo yakasimba, kana kuderedzwa kudzvanywa gasification uye kuti chiedza chemvura yepakati tembiricha iri pasi pe 0 madhigirii, vharanda rekuchengetedza rinoda kupisa kwemhepo. Chengetedzo vharuvhu yezvinosvibisa midhiya, zvichienderana nekudzivirirwa kwekuora kwevharuvhu, funga kuwedzera corrosion isingaputike firimu painopinza vharafu. Gasi rekuchengetedza vharafu rinowanzo kupihwa nevhavhavha yekupfuura zvinoenderana nehukuru hwayo, sechinyorwa chebhuku.
Midziyo yekudzivirira yekumanikidza kuderedza valve
Kudzvanya kudzikisa mavharuvhu ekuisa zvivakwa kazhinji ane mafomu matatu. Mageji ekudzvinyirira anoiswa pamberi uye shure kwevhavha yekudzikisa kuti ifambise kutarisa kwekumanikidza pamberi uye mushure mevhavha. Iko kune yakazara yakavharwa yevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhadzirwe kukundikana kwevhavha inoderedza dhiri,ivhavha mushure mekudzvinyirirwa kunopfuura kudzvinyirirwa kwakajairwa kana kusvetuka,kusanganisira vharuvhu mushure megadziriro. Iyo pombi yekudonha inoiswa pamberi pevhavha kuti icheke valve, basa guru nderokubvisa rwizi runoputika, vamwe vanoshandisa musungo. Basa guru repombi yepombi ndeyekumanikidza kudzikisa kutadza kwevhavha, vhara iyo yekudzikisa vharavha isati yasvika uye mushure mekucheka-vharavhavhavha, vhura iyo bypass valve, nemaoko gadzirisa kuyerera, tamba yenguva pfupi yekutenderera basa, kuitira kugadzirisa kudzvinyirira kuderedza vharafu kana kutsiva iyo yekumanikidza yekudzikisa vharafu.
Midziyo yekudzivirira musungo
Kune marudzi maviri emisungo ane bypass pombi uye hapana bypass pombi padivi pemusungo, condensate kudzoreredza uye condensate kwete kudzoreredza kubhadhara, kuburitsa uye zvimwe zvakakosha zvinodiwa pamusungo, zvinogona kuiswa zvakafanana.
Musungo une bypass valve unonyanya kushandiswa kuburitsa mvura yakawanda yakanyungudutswa kana pombi inotanga kufamba. Paunenge UCHISHANDISA MUSUNGO, HAZVIZVO ZVINOFANIRA KUDHITSA CONDENSATE KUBVUKA NEPOPI YEBYPASS, iyo inogona kuita kuti chiutsi chibude muSYSTEM yeMVURA. Mumamiriro ezvinhu akajairika, usaisa bypass pombi. Chete kana tembiricha yekudziya inodiwa zvakanyanya, iyo yekupisa michina yekuenderera mberi kugadzirwa inofanirwa kuve yakashongedzerwa nebypass pombi.
Nguva dzose kushanda kwefluorine lined anticorrosive valve
1, fluorine yakavharwa epurasitiki vharafu yepakati tembiricha: Kambani yedu akasiyana marudzi efluorine akamisikidzwa epurasitiki mavharuvhu, kushandisa fluorine epurasitiki iF46 (FEP), kushandiswa kwepakati tembiricha hakugone kudarika 150 ℃ (yepakati tembiricha inogona kuita 150 ℃ kwenguva pfupi. nguva, tembiricha yekushandiswa kwenguva refu inofanirwa kudzorwa mu120 ℃), kana zvisina kudaro, zvikamu zvevharuvhu zvinoisa F46 zviri nyore kupfava, deformation, zvichiita kuti vharafu yakavharwa undead, kuvuza kukuru.
Kana tembiricha yepakati inoshandiswa iri pasi pe180 ℃ kwenguva pfupi, uye tembiricha iri pasi pe150 ℃ kwenguva yakareba, imwe mhando yepurasitiki yefluorine inogona kusarudzwa; PFA, asi yakamisikidzwa nePFA fluorine plastiki inodhura kupfuura yakaiswa neF46 mumutengo.
2, usave neiyo negative pressure. Fluorine yakavharwa epurasitiki vharafu inofanirwa kudzivirira kushandiswa kwekumanikidza kwakashata mupombi, kana paine kumanikidza kwakashata, zviri nyore kukonzera fluorine yakamisikidzwa yepurasitiki layer muvhavhavhavha inosvetwa kunze (dhiramu kunze), kupepeta, zvichitungamira kuvhurika kwevhavha nekuvhara kukundikana. .
3, kudzvanywa, kudzvanywa kwakasiyana kunofanirwa kudzorwa munzvimbo inobvumidzwa. Kunyanya mabhero chisimbiso akaiswa fluorine epurasitiki inodzora vharafu, globe vharafu. Nekuti mabhero anogadzirwa ne tetrafluoric zvinhu, kudzvanywa uye kudzvanywa musiyano wakakura, izvo zvinogona kutungamira nyore kuputika kwemabhero.
Bellows seal lined fluorine epurasitiki inodzora vharafu, kushandiswa kwemamiriro ekumanikidza, kudzvanywa kwakakura, kunogona kuchinjirwa kuPTFE kurongedza chisimbiso.
4. Mamiriro epakati efluorine akavharidzirwa epurasitiki valve haafaniri kunge ane zvimedu zvakaoma, makristasi, tsvina, nezvimwewo, kuitira kuti usasakara chigadziko chevhavha uye chigaro chevhavha chakaiswa fluorine plastiki layer kana PTFE mabhero mukushanda kwekuvhura nekuvhara. Iyo yepakati ine yakaoma zvimedu, makristasi, tsvina, sarudzo, spool, chigaro chinogona kushandiswa kuHastelloy.
5, yakarongedzerwa nefluorine plastiki inodzora vharafu inofanirwa kuenderana neinoda kuyerera (Cv kukosha) kusarudzwa kwakaringana kwesaizi yevharuvhu. Paunosarudza, kana zvichienderana nekudiwa kwetraffic (Cv) uye mamwe maitiro ehunyanzvi anoverengerwa saizi yevharuvhu inofanira kusarudzwa uye kuvhurwa kwevharuvhu, senge saizi yevharuvhu yakakura kwazvo, zvirokwazvo ichaita kuti vharafu mukuvhurwa kwenguva yakareba. nguva inomhanya, pasi pemamiriro ediki uye epakati kudzvanywa, zviri nyore kugadzira iyo yevhavha yepakati nevharuvhu tsvimbo nekukanganisa kwevezvenhau uye kuita kuti vharuvhu izununguke, Iyo valve yepakati tsvimbo mukati menguva yakareba pasi pesimba, kunyange ichaita kuti valve stem fracture.
