Mutemo uyu unoshanda pakuiswa kwemavharuvhu emagedhi, mavharuvhu ekumisa, mavharuvhu ebhora, mavharuvhu eshavishavi uye mavharuvhu ekuderedza kumanikidza mumiti yepetrochemical. Kuiswa kwecheki mavharuvhu, mavharuvhu ekuchengetedza, mavharuvhu ekudzora uye matepi eutsi anozoreva kumirairo yakakodzera. Uyu murairo haushande pakuiswa kwemavharuvhu pamvura yepasi pevhu uye mapaipi emvura.

1 Nheyo dzekugadzira valve

1.1 Mavharuvhu anofanirwa kuiswa zvinoenderana nerudzi uye huwandu hunoratidzwa papombi uye chiridzwa chinoyerera diagraph (PID). Kana PID iine zvinodiwa chaizvo zvekuisa nzvimbo yemamwe mavharuvhu, anofanirwa kuisirwa zvinoenderana nezvinodiwa maitiro.

1.2 Mavharuvhu anofanirwa kurongeka munzvimbo dziri nyore kuwana, kushanda uye kuchengetedza. Mavharuvhu pamitsara yemapombi anofanira kurongeka nepakati, uye mapuratifomu ekushanda kana manera anofanirwa kutariswa.

2 Zvinodiwa zvekuisa valve nzvimbo

2.1 Kana pombi dzepombi dzinopinda nekubuda pachigadzirwa ichi dzakabatana nemapombi makuru pamapombi epombi yechirimwa chose,mavharuvhu ekuvharainofanira kuiswa. Nzvimbo yekuisa mavharuvhu inofanira kunge iri pakati kune rumwe rutivi rwenzvimbo yemudziyo, uye mapuratifomu anodiwa anoshanda kana mapuratifomu ekugadzirisa anofanirwa kuiswa.

2.2 Mavharuvhu anoda kugara achishandiswa, kuchengetedzwa nekutsiviwa anofanirwa kuiswa munzvimbo dzinosvikika zviri nyore pasi, pachikuva kana manera.Pneumatic uye magetsi mavharuvhuinofanirawo kuiswa munzvimbo dziri nyore kupinda.

2.3 Mavharuvhu asingade kushandwa nguva nenguva (anoshandiswa chete kana achinge atanga nekumira) anofanirawo kuiswa munzvimbo dzinokwanisa kumiswa manera enguva pfupi kana asingakwanise kuvhiyiwa pasi.

2.4 Kureba kwepakati pevhavha handwheel kubva panzvimbo yekushanda iri pakati pe750 ne1500mm, uye hurefu hwakakodzera

1200mm. Kukwirira kureba kwemavharuvhu asingade kushandwa kazhinji anogona kusvika 1500-1800mm. Kana iyo yekuisa kureba isingagone kudzikiswa uye kazhinji kushanda kunodiwa, chikuva chekushanda kana nhanho inofanira kuiswa panguva yekugadzira. Mavharuvhu ari pamapombi nemidziyo yezvengozi ine ngozi haifanirwe kuiswa mukati mehurefu hwemusoro wemunhu.

2.5 Kana kureba kwepakati pevhavha handwheel kubva panzvimbo yekushanda inodarika 1800mm, sprocket operation inofanira kuiswa. Nharaunda yeketani ye sprocket kubva pasi inofanira kunge inenge 800mm. Iyo sprocket hook inofanirwa kusetwa kuti irembedze kumucheto kwezasi kwecheni pamadziro kana mbiru iri pedyo kudzivirira kukanganisa nzira.

2.6 Kune mavharuvhu akaiswa mumugero, kana chivharo chemugero chinogona kuvhurwa kuti chishande, vhiri remaoko revhavha harifanire kunge rakaderera kupfuura 300mm pasi pechivharo chegoronga. Kana yadzikira kupfuura 300mm, vharafu yekuwedzera tsvimbo inofanira kusetwa kuti igadzire handwheel mukati me100mm pazasi pechivharo chegoronga.

2.7 Pamavharuvhu akaiswa mumugero, paanoda kushandirwa pasi, kana mavharuvhu akaiswa pasi peuriri hwepamusoro (platform),tsvimbo yekuwedzera yevhavha inogona kuiswakuiwedzera kune chivharo chemugero, pasi, chikuva chekushanda. Ivhiri reruoko rwetsvimbo yekuwedzera inofanira kunge iri 1200mm kubva panzvimbo yekushanda. Mavharuvhu ane dhayamita yezita risingasviki kana kuenzana neDN40 uye tambo dzakabatanidzwa hazvifanirwe kushandiswa uchishandisa sprockets kana matanda ekuwedzera kudzivirira kukuvara kwevhavha. Kazhinji, kushandiswa kwe sprockets kana matanda ekuwedzera kushanda mavharuvhu kunofanira kuderedzwa.

2.8 Chinhambwe chiri pakati pevhiri reruoko rwevharuvhu rakarongwa kumativi epuratifomu uye kumucheto kwepuratifomu hakufanirwe kunge kwakakura kupfuura 450mm. Kana iyo yevhavha hunde uye handwheel ichiwedzera muchikamu chepamusoro chepuratifomu uye kureba kuri kushoma 2000mm, haifanire kukanganisa kushanda uye kupfuura kweanoshanda kudzivirira kukuvara kwemunhu.

3 Zvinodiwa pakugadzwa kwemavharuvhu makuru

3.1 Kushanda kwemavharuvhu makuru kunofanirwa kushandisa giya rekufambisa giya, uye nzvimbo inodiwa kune iyo nzira yekutapurirana inofanirwa kutariswa painogadzika. Kazhinji, mavharuvhu ane saizi yakakura kupfuura magiredhi anotevera anofanirwa kufunga nezve kushandisa vharafu ine giya rekutapurirana michina.

3.2 Mavharuvhu makuru anofanirwa kuve akashongedzerwa nemabhureki kune rimwe kana mativi maviri evhavha. Iyo bracket haifaniri kuiswa pane pombi pfupi inoda kubviswa panguva yekugadzirisa, uye kutsigirwa kwepombi hakufaniri kukanganiswa kana valve ichibviswa. Nhambwe iri pakati pebhuraketi nevharuvhu flange inofanirwa kunge yakakura kupfuura 300mm.

3.3 Nzvimbo yekuisa mavharuvhu makuru inofanira kunge iine nzvimbo yekushandisa crane, kana kufunga kumisikidza mbiru inorembera kana danda rekurembera.

4 Zvinodiwa pakuseta mavharuvhu pamapaipi akachinjika

4.1 Kunze kwekunge zvave kudiwa pakuita, vhiri reruoko revharuvhu rakaiswa papombi yakachinjika harifanirwe kutarisa pasi, kunyanya vhiri reruoko revharuvhu papombi yezvengozi ine ngozi inorambidzwa zvachose kutarisa pasi. Mamiriro evharuvhu remaoko anotemwa nenzira inotevera: vertically kumusoro; horizontally; zvakadzika kumusoro ne45 ° kuruboshwe kana kurudyi; zvakadzika zvichidzika ne45 ° kuruboshwe kana kurudyi; kwete kudzika pasi.

4.2 Kune mavharuvhu akaiswa akatwasuka, kana vharuvhu yakavhurwa, tsinde yevharuvhu haizokanganisa nzira, kunyanya kana tsinga yevharuvhu iri kumusoro kana ibvi reanoshanda.

5 Zvimwe zvinodiwa pakugadzirisa valve

5.1 Mitsetse yepakati yemavharuvhu pamapaipi anofanana inofanira kurongeka sezvinobvira. Kana mavharuvhu akarongwa ari pedyo, kureba kwemambure pakati pemavhiri emaoko haafanire kunge ari pasi pe100mm; mavharuvhu anogonawo kudzedzereka kuderedza chinhambwe pakati pemapaipi.

5.2 Mavharuvhu anodiwa kuti abatanidzwe kumuromo wepombi yemidziyo mukuita anofanirwa kuve akabatana nemuromo wepombi yemidziyo kana dhayamita yezita, kudzvanywa kwezita, yekuisa chisimbiso pamusoro pemhando, nezvimwe zvakafanana kana kuenderana nemidziyo pombi muromo flange. . Kana vharafu iine concave flange, nyanzvi yemidziyo inofanirwa kukumbirwa kugadzirisa convex flange pamuromo wepombi inoenderana.

5.3 Kunze kwekunge paine zvakakosha zvinodiwa pakuita, mavharuvhu ari pazasi mapaipi emidziyo yakaita seshongwe, zvinobatidza, uye midziyo yakatwasuka haizorongedzwe musiki.

5.4 Kana pombi yebazi ichiburitswa kubva papombi hombe, vharafu rayo rekuvharika rinofanira kunge riri pachikamu chakachinjika chepombi yebazi pedyo nemudzi wepombi huru kuitira kuti mvura ibude kumativi ese evharuvhu. .

5.5 Iyo yebazi pombi yekuvhara-vharavhavhavha papombi yepombi haiwanzoshandiswa (inongoshandiswa chete painopakira kugadzirisa). Kana pasina manera echigarire, nzvimbo yekushandiswa kwemanera echinguvana inofanira kurangarirwa.

5.6 Kana iyo ye-high-pressure valve yakavhurwa, simba rekutanga rakakura. Bhakiti inofanira kuiswa kuti itsigire valve uye kuderedza kutanga kunetseka. Kukwirira kureba kunofanira kuva 500-1200mm.

5.7 Mavharuvhu emvura yemoto, mavharuvhu emoto, nezvimwewo munzvimbo yemuganhu wemudziyo anofanira kuparadzirwa uye munzvimbo yakachengeteka iyo iri nyore kuti vafambisi vapinde kana pakaitika tsaona.

5.8 Boka revhavha yemoto-kudzimisa kugovera pombi yehuni inopisa inofanira kunge iri nyore kushanda, uye pombi yekugovera haifaniri kunge iri pasi pe7.5m kure nechoto chevira.

5.9 Pakuisa mavharuvhu ane threaded papombi, chinobatika chinobatika chinofanirwa kuiswa pedyo nevharuvhu kuitira nyore disassembly.

5.10 Mavharuvhu ewafer kana butterfly mavharuvhu haafanirwe kubatanidzwa zvakananga kune flange yemamwe mavharuvhu uye pombi fittings. Pombi pfupi ine flange pamigumo miviri inofanira kuwedzerwa pakati.

5.11 Ivhavha haifaniri kuiswa pasi pemitoro yekunze kuti irege kunyanya kunetseka uye kukanganisa kuvhavha
