Manual valve kuvhura nekuvhara, simba rakawandisa
Mhedzisiro: valve ichakuvadzwa kana iri chiedza, uye njodzi yekuchengeteka ichakonzerwa kana ichirema
Zviyero: vharafu remaoko, vhiri reruoko kana mubato, rakagadzirwa zvinoenderana neakajairika manpower, tichifunga nezvesimba rekuisa chisimbiso pamusoro uye inodiwa yekuvhara simba. Nokudaro, hazvibvumirwi kufamba nerevheti yakareba kana kuti yakareba wrench. Vamwe vanhu vanoshandiswa kushandisa wrench, vanofanirwa kunyatsoteerera, kusashandisa simba rakawandisa, zvikasadaro zviri nyore kukuvadza nzvimbo yekuisa chisimbiso, kana kutyora handwheel uye mubato. Vhura uye uvhare valve, simba rinofanira kunge rakagadzikana, kwete kukanganisa. Zvimwe zvikamu zve-high-pressure valves zvine simba rekuvhura nekuvhara zvakafunga nezve simba rekuita uye vheji yakawanda haigoni kumirira. Nevhavhavha yeutsi, isati yavhurwa, inofanira kupiswa pamberi uye mvura yakanyungudutswa ichabviswa. Pakuvhura, ichave inononoka sezvinobvira kudzivirira sando yemvura. Kana vharuvhu yanyatsovhurwa, dzorera vhiri reruoko kumashure zvishoma, kuitira kuti tambo dzive dzakasimba kudzivirira kusununguka uye kukanganisa. Pamavharuvhu edzinde akashama, rangarira nzvimbo yevharuvhu kana yakavhurika zvakazara uye yakavharwa zvakazara kudzivirira kurova nzvimbo yepamusoro yakafa kana yakavhurika zvakazara. Zviri nyore kutarisa kana zviri zvakajairika kana yakavharwa zvizere. Kana hofisi yevharuvhu ikadonha, kana yakakura yakavharirwa pakati pevharuvhu core seals, iyo vharafu hunde chinzvimbo ichachinja kana vharafu yavharwa zvakazara. Apo pombi inoshandiswa kwekutanga, kune tsvina yakawanda mukati, saka valve inogona kuvhurwa zvishoma. Kuyerera kwepamusoro-soro kwepakati kunogona kushandiswa kuisuka, uye zvino inogona kuvharwa zvishoma (haigoni kuvharwa nokukurumidza kana nechisimba kudzivirira tsvina yakasara kubva pakukuvadza nzvimbo yekuvhara). Inogona kuvhurwa zvakare. Dzokorora kakawanda, chenesa tsvina, uye wozoisa mukushanda kwakajairika. Kana vharuvhu ichiwanzovhurwa, panogona kunge paine tsvina pachisimbiso. Kana yakavharwa, nzira iri pamusoro ichashandiswa kuigeza yakachena, uye inobva yavharwa zviri pamutemo. Kana vhiri remaoko uye mubato zvakakuvadzwa kana kurasika, zvinofanirwa kukurumidza kufananidzwa, uye hazvigone kutsiviwa neanochinjika wrench, kuitira kudzivirira kukuvadza mativi mana evhavha hunde uye kutadza kuvhura nekuvhara, zvichikonzera tsaona mukugadzirwa. . Kune mamwe midhiya, kana vharuvhu yakavharwa uye yatonhodzwa kuti ideredze vharafu, mushandisi anofanira kuivhara zvakare panguva yakakodzera kuchengetedza nzvimbo yekuisa chisimbiso isina mitsetse yakanaka. Zvikasadaro, midhiya inoyerera kuburikidza neakanaka seams pahupamhi hwepamusoro uye inobvisa zviri nyore nzvimbo yekuisa chisimbiso. Panguva yekushanda, kana zvikaonekwa kuti kushanda kwakanyanyisa, zvikonzero zvichaongororwa. Kana kurongedza kwakanyanyisa, kunogona kusunungurwa zvakanaka. Kana dzinde revharuvhu rakamonyoroka, vashandi vachaudzwa kuti vagadzirise. Kune mamwe mavhavha, kana akavharwa, zvikamu zvekuvhara zvinopisa uye zvinowedzera, izvo zvinoita kuti zvive zvakaoma kuzarura; kana vachifanirwa kuvhurwa panguva ino, vanogona kusunungura tambo yebhoneti kwehafu yedenderedzwa kuti vabvise kushushikana kwehunde yevharuvhu, vozofambisa vhiri reruoko.

Kuiswa kwakashata kwemavharuvhu munzvimbo yakakwirira yekupisa
Mhedzisiro: tsaona yekudonha
Matanho: kune yakakwira tembiricha mavharuvhu pamusoro pe200 ℃, iwo akaiswa pane yakajairika tembiricha. Mushure mekushandisa zvakajairika, tembiricha inokwira, mabhoti anowedzera nekupisa, uye gaka rinowedzera. Nokudaro, dzinofanira kusimbiswa zvakare, iyo inonzi "hot tightening". Mushandi anofanira kutarisisa kune basa iri, kana kuvuza kuchaitika nyore.

Kwete mvura inonaya panguva inotonhora
Zviyero: kana mamiriro okunze achitonhora, valve yemvura yakavharwa kwenguva yakareba, uye mvura yakaunganidzwa shure kwevhavha ichabviswa. Mushure mokunge vheji yemhepo yamira, iyo condensate ichabviswawo. Pasi pevharuvhu yakafanana neplug, iyo inogona kuvhurwa kuti ibudise mvura.

Nonmetal valve, yakawandisa kuvhura uye kuvhara simba
Zviyero: mamwe mavharuvhu asina-simbi akaoma uye anoputika, uye mamwe acho ane simba rakaderera. Panguva yekushanda, kuzarura nekuvhara simba hakuzove kwakanyanya, kunyanya simba rakasimba. Uyewo chenjerera kuti usarove zvinhu.

Kurongedza kudzvanywa kwevharuvhu nyowani yakanyanya kusimba
Zviyero: kana vharuvhu itsva ichishandiswa, kurongedza hakuzoomerwe zvakanyanya, uye dhigirii rekudonha harizotorwa sedhigirii, kuitira kudzivirira tsvimbo yevhavha kuti irege kudzvinyirirwa zvakanyanya, kukurumidza kupfeka, uye kuita. kuvhura nekuvhara kwakaoma. Unhu hwekuiswa kwevhavhavha hunobata zvakananga kushandiswa, saka zvinodikanwa kuterera kune kutungamira uye chinzvimbo chevhavha, kuvaka kwevhavhavha, zvivako zvekudzivirira valve, bypass uye chiridzwa, valve packing replacement.

Hapana nzvimbo yekushanda munzvimbo yekuisa
Matanho: nzvimbo yekuisa yevhavha inofanira kunge yakanakira kushanda; kunyange kana kuiswa kwacho kwakaoma kwenguva, zvinodikanwawo kufunga nezvebasa renguva refu remushandisi. Zviri nani kuita kuti gumbo remaoko revhavha rinoputika nebhokisi (kazhinji 1.2m kure nepasi rekushanda), kuitira kuti kuzarura nekuvhara kwevhavha kunowedzera hupfumi. Gumbo reruoko rwevharuvhu yekumhara richatarisa kumusoro, uye usarerekera kudzivirira kushanda kwakashata. Vhuru yemuchina wakatsamira pamadziro nemidziyo zvichasiyawo nzvimbo yekuti mushandisi amire. Hazvina kuchengetedzeka kushanda mudenga, kunyanya muasidhi uye alkali, muchetura media, nezvimwe.

Mavharuvhu akagadzirwa nemhedzisiro brittle zvinhu
Matanho: kuiswa uye kuvaka kunofanirwa kungwarira kudzivirira kurova valve yakagadzirwa nebrittle zvinhu. Usati waiswa, tarisa vharafu, tarisa kutsanangurwa uye modhi, uye ona kana paine kukuvadzwa, kunyanya kune yevhavha hunde. Uyewo tenderera nguva shomanana kuti uone kana yakatsvedza, nokuti mukufambisa kwekufambisa, inonyanya kurova skewed stem. Uyewo bvisa tsvina kubva pavhavha. Paunenge uchisimudza valve, tambo haifaniri kusungirirwa pagumbo remaoko kana tsinde, kuitira kuti urege kukuvadza kune zvikamu izvi, uye ichasungirirwa paflange. Iyo pombi yakabatana nevhavha inofanira kucheneswa. Mhepo yakadzvinyirirwa inogona kushandiswa kupeperetsa zvisaririra zvesimbi oxide, jecha rematope, welding slag uye mamwe akawanda. Izvi zvakasiyana-siyana hazvisi nyore chete kukwenya chisimbiso pamusoro pevhavha, asiwo zvinogona kuvhara vheji duku uye kuita kuti isashande. Kana uchiisa screw valve, iyo yekuisa chisimbiso (hemp uye lead mafuta kana polytetrafluoroethylene raw material bhandi) ichaputirwa patambo yepombi, uye haizoisirwe muvharuvhu, kuitira kudzivirira vharafu kuti isaungane uye kukanganisa kutenderera kwepakati. . Paunenge uchiisa iyo flange valve, teerera kuomesa mabhaudhi symmetrically uye zvakaenzana. Iyo vharafu flange uye pombi flange inofanirwa kuenderana neyakajeka clearance, kuitira kuti udzivise kudzvinyirira kwakanyanya kana kuputika kwevhavha. Kune brittle zvinhu uye yakaderera simba mavharuvhu, kutarisisa kwakakosha kunofanirwa kubhadharwa. Kuti vheji inosungirirwa nepombi, kuputika kwemavara kunofanira kuitwa kutanga, ipapo chikamu chakavharwa chichavhurwa zvakakwana, uye ipapo valve ichave yakasungirirwa.
