Valve yakajairika pfungwa: vharafu chisimbiso uye kuita
(I) Chisimbiso chevhavha uye kushanda
1, vharuvhu mumusangano wekupedzisira inofanira kuitwa mushure mekuedzwa kwekuita, kutarisa kana chigadzirwa chacho chinosangana nezvinodiwa zvekugadzira uye kuti inosangana nemitemo yenyika. Kukanganisa mumidziyo yevharuvhu, mabhesi, kurapwa kwekupisa, machining uye kusangana zvinogona kuburitswa panguva yekuyedzwa. Miedzo yakajairwa inosanganisira bvunzo yesimba regomba, yekuisa chisimbiso bvunzo, yakaderera kuisirwa chisimbiso bvunzo, chiitiko bvunzo, nezvimwe, uye zvinoenderana nezvinodiwa, bvunzo inotevera ichaitwa mushure mekupasa bvunzo zvakateerana.
2, kuyedza simba: vharafu inogona kutariswa semudziyo wekumanikidza, saka inoda kuzadzisa zvinodiwa zvekutakura svikiro repakati pasina kubuda, saka muviri wevharuvhu, chivharo chevhavha uye zvimwe zvikamu zvechisina hazvifanirwe kuvepo zvinokanganisa simba rekutsemuka. , yakasununguka pores, slag nezvimwe zvikanganiso. Pamusoro pekuongorora kwakasimba kwekuonekwa uye mukati mehutano hwemukati usina chinhu, mugadziri wevhavha anofanirawo kuita simba rekuedza rimwe nerimwe kuti ave nechokwadi chekushanda kwevhavha.
3, chikonzero chekudonha kwevhavha yekumanikidza kuderedza
Sechikamu chakakosha cheiyo hydraulic system, basa guru rekumanikidza kudzikisa valve nderekuita kuti kubuda kwekumanikidza kweiyo system kugare kwakadzika kupfuura mwero weiyo inlet pressure, kuchengetedza kugadzikana kwekubuda kwekumanikidza kwehurongwa, uye iyo kubuda kwekumanikidza kweiyo system hakukanganiswe neiyo inlet kudzvanywa uye kuyerera kwekuchinja; Zvisinei, kana chisimbiso chepamusoro chekumanikidza kuderedza kuvhara kwevhavha, haisi kungokanganisa kugadzirwa kwemazuva ose, asiwo kunokonzera kurasikirwa kwemafuta e hydraulic uye kusvibiswa kwezvakatipoteredza; MuMarine hydraulic system, iyo yekudzikisa kudzvinyirira valve sechinhu chikuru chekutonga, kukosha kwayo kwekuisa chisimbiso hakufanirwe kuderedzwa. Mushure mekutsvakurudza pamwe chete uye kuongororwa nenyanzvi dzinoshanda dzakaona kuti chisimbiso pakati pesleeve yekubatanidza yevhavha inoderedza uye muviri wevhavha inonyanya kutsamira paO-ring pakati pesleeve yekubatanidza uye mukati memadziro emuviri wevhavhavha yekuisa chisimbiso che circumferential. kuisa chisimbiso kamwe chete kushanda, kubuda kwayo kwekunze hakudzivisiki.
4, butterfly valve test uye kuisirwa uye nzira dzekugadzirisa matambudziko
Butterfly valve ingave manual, pneumatic, hydraulic, electric parts is hard debugging vasati vabuda, mushandisi kana kuongororazve kuita chisimbiso, kumativi ose maviri ekutumira uye kunze kwenyika kuchagadziriswa zvakafanana, kuvhara disc valve, kudzvinyirira pakusveta. divi, mune ekisipoti divi kuona kana leak chiitiko, pamberi kutongwa, simba mupombi anofanira kuvhura dhisiki ndiro, kudzivirira kukanganisa chisimbiso.
Kunyangwe zvigadzirwa zvakanyatsoongororwa uye kuyedzwa zvisati zvabuda mufekitori, kune otomatiki screw displacement yezvimwe zvigadzirwa panguva yekufambisa, izvo zvinoda kugadziridzwa, pneumatic, hydraulic, nezvimwewo, ndapota verenga mirairo yekushandisa yeinotsigira kutyaira mudziyo.
Kana iyo yemagetsi drive disc valve ichisiya fekitori, iyo yekuvhura uye yekuvhara sitiroko yemuchina wekutonga yakagadziridzwa. Kuti udzivise kutungamira kwekuchinja kwemagetsi kwakashata, mushandisi panguva yekutanga mushure mekuchinja simba, tanga wakavhurika bhuku kune hafu yakavhurika nzvimbo, zvinoenderana nemagetsi switch kuti utarise kwainotungamira ndiro yechiratidzo uye vharafu. nzira yakavharwa inogona kuenderana.
5. kana chiyero chemhando yekugadzirisa, indasitiri otomatiki yekudzora sisitimu inogamuchira chiratidzo chekutonga kupedzisa kudzora kuyerera kwepombi yepakati, kudzvanywa, tembiricha uye mamwe maitiro maparamita. Pneumatic control valve inoratidzirwa nekudzora kuri nyore, kukurumidza kupindura, uye nemukati yakachengeteka, haidi kutora matanho ekuputika-uchapupu zvakare.
6, Stainless simbi butterfly vharafu mukuita kwekushandisa ngura chiitiko. Kuburikidza ne metallographic chimiro chekuongorora, kusvibisa bvunzo kumeso, kupisa kupisa bvunzo kumeso, SEM uye kumwe bvunzo, zvinowanikwa kuti chinhu chakakosha chekuora kwezvinhu ndechekuti iyo carbide inodonha ichitevedza miganhu yezviyo muzvinhu kuti igadzire chrome-varombo nzvimbo, zvichikonzera ngura yesimbi isina simbi butterfly valve. Iyo simbi isina simbi butterfly valve yakagadzirwa neCF8M yakasvibiswa panguva yekushandiswa. Mushure memazuva ese ekupisa kupisa, chimiro cheaustenitic simbi isina tsvina chinofanira kunge chiri austenitic pane tembiricha yekamuri, uye kushorwa kwekuora kwakanaka. Kuti uongorore chikonzero chekuora kwevhavhavhavhavhavha, masampuli akatorwa kubva mairi kuti aongororwe.
(ii) Flange chisimbiso uye leakage chisimbiso kurapwa nzira
Pane zvinhu zvakawanda zvinokanganisa kuiswa chisimbiso cheflange. Iwo makuru ndeaya: bolt preload; Kuisa chisimbiso pamusoro pemhando; Gasket performance; Flange kuoma; Mamiriro ekushanda. ANSI flanges akagadzirwa neAmerican National Standards Institute kuti ape indasitiri yemafuta negasi tekinoroji yakakodzera uye inoshanda yekuisa chisimbiso kwemakumi emakore. Nekudaro, sezvinodiwa zveindasitiri yemafuta negasi zvachinja, kushomeka kwe ANSI flange kwakafumurwa. Iyo musimboti wekudhura-kushanda, kuchengetedzwa kwezvakatipoteredza, uye hutano hwevanhu uye chengetedzo vimbiso ndizvo zvinosangana nevashandisi nemakondirakiti muzana ramakore re21.
Mhedziso:
Iyo itsva yekugadzira uye kuiswa kwegadziriro yekutonga, kuitira kuti ive nechokwadi chokuti mutongi anogona kushanda zvakajairika paanenge achityaira, uye kuita kuti hurongwa huve hwakachengeteka, vheji itsva isati yaiswa, inofanira kutanga yatarisa chiratidzo chezita revhavha rinoenderana nezvinodiwa zvekugadzira. Mapurojekiti anotevera anofanirawo kugadziriswa. Basic kukanganisa muganhu; Kutsauka kwakakwana kwesitiroko; Dzokera kuvarombo; Dead zone; Leakage (munyaya yezvinodiwa zvakasimba). Kana iri iyo yepakutanga hurongwa hwevhavha inogadzirisa yakave yakagadziridzwa, kunze kwecheki iri pamusoro, asiwo inofanira kuva yekare yevhavha yekuputira bhokisi uye zvikamu zvakabatana zvechisimbiso chekuvhara.
Typical valve gedhi vharafu: wedge gedhi vharafu uye parallel gedhi vharafu gedhi vharafu rinoshandiswa seyakachekwa-yepakati svikiro, yakazaruka yakazara kana iyo yese ichiyerera yakananga, iyo yepakati inomhanya yekumanikidza kurasikirwa i* * diki. Mavharuvhu emagedhi anowanzo akakodzera kumamiriro ekushanda asingade kuvhurika nekuvharwa nguva nenguva, uye chengetedza gedhi rakazaruka kana kuvharwa zvizere. Haina kuitirwa kushandiswa seregulator kana throttling.
Ivhavha yegedhi inoshandiswa sechidimbu chekucheka, kuyerera kwese kwakananga kuburikidza kana yakazaruka zvakakwana, uye kurasikirwa kwekumanikidzwa kwepakati inomhanya ndeye ** * diki. Mavharuvhu emagedhi anowanzo akakodzera kumamiriro ekushanda asingade kuvhurika nekuvharwa nguva nenguva, uye chengetedza gedhi rakazaruka kana kuvharwa zvizere. Haina kuitirwa kushandiswa seregulator kana throttling. Kune IYO YEKUPEDZERA kuyerera ZVIRI MUKATI, gedhi rinogona kukonzera kuzununguka kwegedhi mumamiriro ekuvhurwa kwenzvimbo, uye kudedera kunogona kukuvadza nzvimbo yekuisa chisimbiso yegedhi nechigaro, uye throttle ichaita kuti gedhi ritambure nekukukurwa kwepakati. .
Kubva pachimiro chechimiro, mutsauko mukuru imhando yechinhu chekuisa chisimbiso chinoshandiswa. Zvinoenderana nechimiro chezvinhu zvekuisa chisimbiso, mavharuvhu emagedhi anowanzo kupatsanurwa mumhando dzakasiyana siyana, senge wedge gedhi mavharuvhu, anofanana mavharuvhu egedhi, anofanana maviri egedhi mavharuvhu, wedge magedhi maviri egedhi, nezvimwewo ** Mafomu anowanzo shandiswa mavharuvhu egedhi uye wedge. parallel gedhi mavharuvhu.
