Precision Stainless simbi yetsono vharafu ivharuvhu inogadziriswa universal valve kabhoni simbi yekugadzira hunyanzvi mamiriro

Sei vharafu yetsono ivhavha inogona kugadziriswa, nokuti tsono yevhavha spool ikona yakapinza kwazvo, setsono yakaiswa pachigaro, saka zita racho. Iyo ine huwandu hwakasiyana hwekushandisa, senge yekucheka chinhambwe chekucheka murazvo, kugadzirisa murazvo tembiricha knob ndiyo valve yetsono.
Precision Stainless simbi yetsono vharafu yakanaka kuyerera kuita. Nzira yekuyerera yevhavha yetsono yakananga kuburikidza nefomu, kuitira kuti kuyerera kwepakati hakuchadi kutendeuka, kusvika pamwero mukuru kuderedza mukana wepakati pekuisa. Naizvozvo, yakanyatsokodzera kune yakakwira viscosity, kumiswa, pulp uye dzimwe nzvimbo dzisina kuchena dzenhau.
Precision Stainless simbi yetsono vharafu 2 yakakura kuita:
1. Kucheka kushanda: Kuita kwakanaka kwekucheka kwevhavhavha yetsono. Chimwe chezvinhu zvinonyanya kukosha zvevhavhavha yetsono ndeyokuti kushamwaridzana pakati pe spherical spool uye chigaro chekugara chiri mumutsara wekubatanidza fomu, iyo inoderedza nzvimbo yekubatana uye inowedzera kuderedza kudonha kwevhavha. Chechipiri ndechekutora matanho ekugadzira, senge lining lead, lining aluminum, lining engineering mapurasitiki, lining rabha rabha uye akasiyana ekugadzira rabha sarudzo.
2, anti-corrosion performance: Stainless simbi yetsono valve muviri wekutanga kudzivirira ngura, kunyanya kusarudzwa kwakaringana kwezvinhu. Kunyange zvazvo ruzivo rwekudzivirira kuparara rwakapfuma zvikuru, hazvisi nyore kusarudza iyo yakarurama, nokuti dambudziko rekuora rakaoma zvikuru. Kuoma kwekusarudza muviri wevhavha chinhu ndechokuti haigoni kungofunga nezvedambudziko rekuora, asiwo inofanira kufunga nezvekumanikidzwa uye kupisa kwekushisa, kana hupfumi hunonzwisisika, kana kutenga kuri nyore uye zvimwe zvinhu.
Tsono vharafu mapoinzi ekutarisisa: [Nzira yekuisa: kukwirisa padivi kana kukwirisa kumusoro sarudzo]
Kugadziriswa kwevharuvhu yetsono kunofanirwa kuongororwa isati yaiswa, zita revharuvhu rinofanira kuenderana neyakajairwa yenyika "Universal Valve Mark" GB 12220 zvigadziro. Nokuda kwevhavha iyo kushanda kwayo kwakakura kudarika 1.0MPa uye inobata basa rekucheka pane pombi huru, simba uye muedzo wakaoma wekushanda unofanirwa kuitwa usati waiswa, uye valve inokwanisa inogona kushandiswa. Muedzo wesimba, kudzvanywa kwebvunzo ndeye 1.5 nguva yekumanikidza kwezita, nguva yacho haisi pasi pe5min, goko revharuvhu, kurongedza kunofanirwa kuve kwakakodzera pasina kuvuza. Tightness bvunzo, bvunzo kudzvanywa ndeye 1.1 nguva dzezita rekumanikidza; Nguva yebvunzo inosangana nezvinodiwa zveGB 50243.
Chiyero chekushandisa: yakajairika mhando: inokodzera yakaderera uye yepakati kudzvanywa, hapana hunhu anticorrosion zvinodiwa zvevacuum mhando: inokodzera tembiricha, yakanyanya-yakakwirira tembiricha, yakaderera, yepakati uye yakanyanya kudzvanywa, hapana yakakosha anticorrosion zvinodiwa pachiitiko chekudzivirira chando.
Mamiriro ehunyanzvi ekabhoni simbi forgings yevharuvhu (mbiri) Imwe neimwe yevira yekupisa yekupisa yekubikira inofanira kunge iri bvunzo inorema, kana iyo imwechete yekupisa yekupisa yekubikira ichisanganisira nhamba dzinopfuura mbiri dzechoto, imwe neimwe inomonereka nhamba yevira inofanira kunge iri tensile bvunzo. Kana mafirita ari madiki, hazvigoneke kugadzira zvidhinha zvidiki zvekuyedza bvunzo pazvivharo kana kutora ese mabhuroki ebvunzo anoenderana neiyo huru deformation nzira, uye hazvigoneke kumisa seti yekumusoro forging test blocks, ipapo 1% yebatch kana zvidimbu gumi (tora iyo shoma kukosha) inogona kutorwa kuitira kuomarara bvunzo. Muedzo wekumanikidza uchaitwa mushure meNDT uye uchaitwa chidimbu nechidimbu. The forging unit ichaita basa remhando ye test forging.

Nzira yekuedza
Tensile test
Imwe neimwe yekupisa kurapwa forgings ichaiswa kune tensile bvunzo. Kana mafogi ane imwechete kupisa kurapwa achisanganisira anopfuura maviri anomonereka manhamba echoto, imwe neimwe inotenderedza nhamba yechoto ichaiswa pasi pekuyedzwa kwakasimba.
Pasi pemamiriro ekugadzirisa kupisa kwekupisa, kukanganisa kwekushisa kuri mukati me14 ℃ yevhu, uye kune yakakwirira uye yakakwirira yekurekodha michina, iyo inotenderedza yevira nhamba yakabatana, uye chete tensile bvunzo inodiwa.
Iyo tensile bvunzo nzira ichaitwa zvinoenderana nezvinodiwa zveGB/T 228.
Kana mafogi ari madiki zvakanyanya, hazvigoneke kugadzira madiki madiki ebvunzo mabhuroki ekutemesa bvunzo pane forgings kana kutora ese mabhuroki ebvunzo anoenderana neiyo huru deformation nzira, uye hazvigoneke kuseta seti yekumusoro forging bvunzo. zvidhinha, ipapo 1% yebatch kana 10 zvidimbu (tora diki kukosha) inogona kutorwa yekuomarara bvunzo.
Muedzo wekuoma
Forgings kuomarara nzira yekuyedza zvinoenderana neGB/T 231.1.
Impact test
Forgings inokanganisa bvunzo nzira zvinoenderana neGB/T 229.
Kuedza kusina kuparadza
Iyo ultrasonic yekuyedza uye magineti particle yekuyedza nzira dzefogi dzinoitwa zvinoenderana nezvinopihwa zveGB/T4730.
Pressure test
Iyo yekumanikidza bvunzo nzira yekumanikidza forgings ichaitwa zvinoenderana neGB/T 13927.
Pressure forgings inofanirwa kuongororwa mushure mekugadzira machining kuona kuti hapana kuvuza.
Mutemo wekuongorora
Izvo zvinhu zvekuongorora uye nhamba yefogi yegiredhi rega rega inotsanangurwa muTebhu 5.
Tafura 5 Forging yekuongorora zvinhu
Kana iyo mechanical properties test test results isingaenderane nezvinodiwa zveTafura 4, kupisa kwekupisa kuchadzoserwa zvakare maererano ne3. 3, uye sampuli block ichaitwa maererano ne3.5, uye muedzo. ichaitwa maererano nezvinopihwa ne5.1. Zvisinei, nhamba yekurapazve kupisa haifaniri kudarika kaviri.
Muedzo wekumanikidza uchaitwa mushure meNDT uye uchaitwa chidimbu nechidimbu. The forging unit ichaita basa remhando ye test forging.
Order chinodiwa
Tafura yeodha kana runyoro rwekubvunza runosanganisira zvinotevera zvirimo:
a} chigadzirwa chekugadzira dhizaini, ine tafura uye hutsinye, kushivirira, nhamba yegiredhi yezvinyorwa uye zvimwe zvinodiwa;
b) Mutengesi maitiro ekugadzira uye kudhirowa kudhirowa (yakatenderwa naDemander kana zvichidikanwa);
c) Kurapa kwekupisa uye zvimwe zvinodiwa zvinogona kutaurirana nemapato ese.
d) Zvinodiwa zvekugamuchirwa uye zviri mukati kuti zviwedzerwe.
Iye Demander achazivisa iyo yekuumba unit mukati menguva yakatemwa mukondirakiti kana ikawana tsvina muchirongwa chekuongorora chigadzirwa kana machining. Kana pasina gadziriro, haifaniri kudarika mazuva makumi matatu.
Mafungiro anofungidzirwa kuti araswe achachengetwa kwemazuva makumi matatu kubva pazuva rekutumira mushumo webvunzo, panguva iyo iyo forging unit inogona kukumbira kuongororwazve.
Maka uye chitupa chemhando
Mushure mekunge maforgings apfuura ongororo, chiratidzo chekufanirwa chinofanira kusungirirwa. Zviri mukati mechiratidzo zvinosanganisira:
a) Fekitari bhurocha kana fekitori label,
b) Kodhi yezvinhu;
C} kodhi yekurapa kupisa;
d) Kugadzira nguva yemuromo;
e)Mucherechedzo mucherechedzo.
Kune mafogi ane huremu hudiki uye mamark akaoma, mamaki anogona kushandiswa pachinzvimbo, asi mamaki anofanirwa kunge ari munzvimbo isingakanganisi kushandiswa kwefogi.
Iyo forgings ichaunzwa ine vimbiso yemhando inosimbisa kuti mhando yefogi inosangana nezvinodiwa zvechiyero ichi.
