3. Kuderedza kumanikidzwavharuvhunzira yekuedza kumanikidzwa

① Kuedza simba kwevharuvhu inoderedza kumanikidzwa kunowanzo unganidzwa mushure mekuedzwa kumwe chete, uye kunogonawo kubatanidzwa mushure mekuedzwa. Nguva yekuedza simba: 1min neDN<50mm; DN65 ~ 150mm yakareba kupfuura 2min; Kana DN yakakura kupfuura 150mm, yakareba kupfuura 3min. Mushure mekunge maburi asunganidzwa kuzvikamu, kumanikidzwa kwakanyanya ka1.5 mushure mekushandiswa kwevharuvhu inoderedza kumanikidzwa, uye kuedza simba kunoitwa nemhepo.
② Bvunzo yekusimba inoitwa zvichienderana nechinhu chaicho chinoshanda. Pakuyedza nemhepo kana mvura, bvunzo iyi inoitwa ne1.1 kakapetwa kanomwe kanomwe kanomwe; Pakuyedza nemhepo, inoitwa nemhepo inomanikidzwa kushanda yakakwira inobvumirwa patembiricha yekushanda. Musiyano uripo pakati pemhepo inopinza nekumanikidzwa kwemhepo haifanirwe kunge uri pasi pe0.2MPa. Nzira yekuedza ndeiyi inotevera: mushure mekunge mhepo inopinza yagadziriswa, sikuruu yekugadzirisa yevharuvhu inogadziriswa zvishoma nezvishoma kuitira kuti mhepo inopinza igone kuchinjwa zviri nyore uye nguva dzose mukati mehuwandu hwepamusoro uye hushoma, pasina kumira kana kuvharika. Pavharuvhu inoderedza kumanikidzwa kwemhepo, kana mhepo inopinza yabviswa, vharuvhu inovharwa uye vharuvhu inogurwa, uye mhepo inopinza ndiyo yakanyanya uye yakaderera. Mukati memaminitsi maviri, kukosha kwekumanikidzwa kwemhepo kunofanira kuenderana nezvinodiwa. Pavharuvhu dzinoderedza kumanikidzwa kwemvura nemhepo, kana mhepo inopinza yagadziriswa uye mhepo inopinza iri zero, vharuvhu inoderedza kumanikidzwa inovharwa kuti ivharwe, uye hapana kubuda mukati memaminitsi maviri kunofanirwa.

4. Vharuvhu yeshavishavinzira yekuedza kumanikidzwa

Kuedza simba kwevharuvhu remapuruguru rinobuda nemhepo kwakafanana nekwevharuvhu yepasi rose. Kuedza kushanda kwevharuvhu remapuruguru kunofanira kuunza nzira yekuyedza kubva kumagumo ekupinda, ndiro yemapuruguru inofanira kuvhurwa, rimwe divi rinofanira kuvharwa, uye kumanikidzwa kwejekiseni kunofanira kusvika pahuwandu hwakatarwa; Mushure mekutarisa kuti hapana kubuda kwemvura mupakeji nezvimwe zvisimbiso, vhara ndiro yemapuruguru, vhura rimwe divi, uye tarisa kuti hapana kubuda kwemvura muvharuvhu remapuruguru. Mavharuvhu emapuruguru anoshandiswa kudzora kuyerera kwemvura haaite bvunzo dzekushanda kwesealing.

5.Vharuvhu yepuraginzira yekuedza kumanikidzwa
①Kana vharuvhu yepuragi yaongororwa simba, nzira yacho inopinzwa kubva kumucheto mumwe, nzira yasara inovharwa, uye puragi inotenderedzwa kusvika panzvimbo yakavhurika yekushanda kuti iongororwe, uye muviri wevharuvhu hauonekwe uchidonhedza mvura.
② Mukuyedza kwekuvhara, jira rekudzivirira rinofanira kuchengetedza kumanikidzwa mugomba rakaenzana nepassage, kutenderedza plug kusvika panzvimbo yakavharwa, kutarisa kubva kune rimwe divi, uye wozotenderedza plug 180° kuti udzokorore bvunzo iri pamusoro apa; Vharuvhu yeplug ine nzira nhatu kana ina inofanira kuchengetedza kumanikidzwa mugomba rakaenzana nemugumo mumwe wepassage, kutenderedza plug kusvika panzvimbo yakavharwa, kupinza kumanikidzwa kubva kumagumo eAngle ekurudyi, uye kutarisa kune rimwe divi panguva imwe chete.
Pamberi pekuyedzwa kwevharuvhu remapulagi, zvinotenderwa kuisa jira remafuta anonyorovesa asina acidic pamusoro pechisimbiso, uye hapana madonhwe emvura anobuda kana akawedzera anowanikwa mukati menguva yakatarwa. Nguva yekuyedzwa kwevharuvhu remapulagi inogona kuva pfupi, inowanzo tsanangurwa se l ~ 3min zvichienderana nedhayamita rezita.
Vharuvhu yepuragi yegesi inofanira kuongororwa kuti ione kana mhepo yakasimba uye ine simba rakapetwa ka1.25 pane simba rekushanda.

6.Vharuvhu yedhayafuranzira yekuedza kumanikidzwa

Kuedza simba revharuvhu rediaphragm kunounza nzira yekupinda kubva kumagumo ese, kunovhura dhisiki revharuvhu, uye kunovhara rimwe divi. Mushure mekunge kumanikidzwa kwebvunzo kwakwira kusvika pamutengo wakatarwa, zvinoonekwa kuti muviri wevharuvhu nechifukidziro chevharuvhu hazvina kubuda. Wobva waderedza kumanikidzwa kusvika pakumanikidzwa kwebvunzo yekuedza kuoma, vhara dhisiki revharuvhu, vhura rimwe divi kuti uongorore, hapana kubuda kwebvunzo kunoratidzwa.

7.Vharuvhu yekumisauyevharuvhu yekukwevanzira yekuedza kumanikidzwa
Kuedza simba kwevharuvhu yepasi rose nevharuvhu yekukwesha kunowanzoiswa vharuvhu yakaunganidzwa mu pressure test rack, kuvhura vharuvhu disc, kuisa medium kusvika pamutengo wakatarwa, uye kutarisa kana muviri wevharuvhu nevharuvhu zviri kudikitira uye zvichibuda. Kuedza simba kunogonawo kuitwa mumwe nemumwe. Kuedza kwekukwesha kunongoitirwa vharuvhu yekumisa chete. Munguva yekuyedza, tsinde yevharuvhu yekumisa inenge yakamira, vharuvhu disc inovhurwa, medium inounzwa kubva pasi pevharuvhu disc kusvika pamutengo wakatarwa, uye kurongedza negasket zvinotariswa. Kana zvakwana, vhara vharuvhu disc wovhura rimwe divi kuti uone kana paine kubuda kwemvura. Kana bvunzo yekusimba nekubata kwevharuvhu ichizoitwa, bvunzo yekusimba inogona kutanga yaitwa, uye kudzvanywa kunoderedzwa kusvika pamutengo wakatarwa webvuruvhu, uye kurongedza negasket zvinotariswa. Wobva wavhara vharuvhu disc, vhura magumo ekubuda kuti uone kana sealing surface ichibuda.
