8.1 mucherechedzo
8.1.1 Nzira yekubatanidza yemhando yechigadzirwa ichatevera zviga zveJB/T4018. Kana goko riri WCB uye WC1, WC6 uye WC9 zvinhu, iyo valve chigadzirwa modhi ichaunganidzwa zvinoenderana nenzira yakatsanangurwa muJB/T4018 pacarbon simbi uye cr al-V alloy simbi zvichiteerana.
8.1.2 Kana muviri wevharuvhu uri WCB, WC1, WC6, WC9 zvinhu, nhamba yechiratidzo chayo inogona kuiswa pamutumbi wevharuvhu.
8.1.3 Metal nameplates achaiswa pazvigadzirwa zvevharuvhu, uye nzvimbo yekusungira uye saizi yemazita emazita ichaenderana nedhizaini yedhizaini. Ndokumbira utarise Appendikisi F yezviri mukati mezita rezita
8.1.4 Zvikamu zvakakosha uye zvinomanikidza welds zvinopfuura kuongororwa zvichaverengerwa kana kucherechedzwa zvakananga, uye mamakisi achaiswa chiratidzo munzvimbo ine kuderera kwakanyanya kushushikana, kunyanya kudzivirira iyo stress concentration zone, shape mutation uye welding heat yakakanganiswa zone, izvo zvisingazotadzisi kutonga kwemhedzisiro yekuedzwa kusingaparadzi.
8.1.5 Mucherechedzo wevharuvhu uye pendi yechiratidzo Chikumbiro JB/T 106. Pamutumbi wakagadzirwa neWCB, chiziviso nekupenda zvichareva kupihwa kwekabhoni simbi; Kune miviri yevharuvhu yakagadzirwa neWC1, WC6, WC9, iyo yekuzivikanwa coating ichareva izvo zvinopihwa zvealloy simbi zvinhu. Shanduko yemuvara wependi inobvumidzwa pachikumbiro chemutengi. Mamwe mamakisi achaitwa zvinoenderana nemwero wakakodzera.
8.2 kurongedza
8.2.1 Isati yaputirwa, valve inofanira kupendwa maererano ne8.1.5, uye zvikamu zvisina kupendwa kana nzvimbo yakagadziriswa isina rust layer inofanira kuputirwa nemafuta anodzivirira ngura.
8.2.2 Chisimbiso chepamusoro, magumo akasungwa, magumo ane thread uye mukati mevhavhavha kumativi ose maviri eflange inofanira kuchengetedzwa nemapulagi kana mahwendefa ekuvhara, uye inofanira kuva nyore kuunganidza uye kuparadzanisa.
8.2.3 Zvigadzirwa zvevhavha zvichaiswa uye kutumirwa maererano nebhokisi rekutakura: Mavhavha ane vhoriyamu yakakura anogona kutakurwa asina kupfeka maererano nezvinodiwa nehurongwa, asi ichava nechokwadi chokuti haazokuvadzi panguva yekufambisa.
8.3 chengeta
Zvigadzirwa zvevharuvhu zvinofanirwa kuchengetwa muimba yakaoma, ine mhepo inofefetera uye yakaunganidzwa zvakatsvinda sezvinodiwa. Kuvhura chengetedzo kana kurongedza zvigadzirwa hazvibvumidzwe.
8.4 chekufambisa
8.4.1 Panguva yekufambisa, valve disc ichavharwa uye cheki chevhavha disc ichagadziriswa; Ivhavha yevhavha inofanira kunge iri munzvimbo isina kuvharwa; Huremu hwevhavha yevhavha huchabviswa kubva pamucheka, kuiswa zvakasiyana, uye chigadziko chakagadziriswa. Iyo yedivi flange kana yebazi pombi welding groove kumagumo ese evharuvhu chiteshi yakavharwa nekavhavha ndiro kana plug kudzivirira tsvina netsvina kupinda.
8.4.2 Chikamu chiri pachena chehunde chichachengetedzwa.
