Mukushandiswa kwezuva nezuva kwevashandisi vevhavhavhavha yevhavhavha yakakura, tinowanzoratidza dambudziko, kureva kuti, guru guru revhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharisiwa rinoshandiswa kusiyanisa kudzvinyirirwa rinenge rakakura midhiya, senge mhepo, high-pressure mvura uye mamwe mabasa anomanikidzika, kazhinji zvakaoma zvikuru kuvhara, zvisinei kuti zvakaoma sei kuvhara, nguva dzose akawana kuti pachava nekubuda kwechiitiko, zvakaoma kuvhara zvakasimba zvinokonzerwa nekugadzirisa dambudziko rekugadzirisa dambudziko uye kuguma kwevhavhavha. mwero weiyo torque yekubuda haina kukwana. ‍

Ongororo yezvikonzero zvekuomerwa nekuchinja mavharuvhu makuru edhayamita

The general horizontal limit limit output force yemunhu mukuru i60-90kg, zvichienderana nekukura kwemuviri.

Iyo general flow direction yevhavhavhavhavha inogadzirwa kuti ive yakadzikira mukati uye yakakwira kunze, kana munhu akavhara vharafu, muviri wemunhu unosundidzira ruoko kutenderedza kuti utenderere, kuitira kuti chivharo chevharuvhu chiende pasi kuti chizadzike kuvharwa, izvo zvinodiwa kukunda musanganiswa wemasimba matatu, anoti:

1) Axial kumusoro kukanda Fa;

2) kurongedza uye stem friction simba Fb;

3) Dzinde uye vharafu musimboti kusangana friction Fc

Torque yese ndeye ∑M=(Fa+Fb+Fc)R

Sezvinogona kuonekwa, iyo yakakura ye caliber, iyo yakakura yeaxial thrust force, kana iri pedyo neyakavharwa, iyo axial thrust simba inenge iri pedyo nekumanikidzika kweiyo pombi network (nekuda kwekuvharwa kweP1-P2 ≈ P1, P2 = 0)

Kana DN200 caliber butterfly valve ichishandiswa pa 10bar steam pombi, yekutanga chete kuvhara axial thrust Fa = 10 × πr2 = 3140kg, uye yakatwasuka circumferential simba rinodiwa pakuvhara riri pedyo nemuganho wehorizontal circumferential simba rinogona kubuda kumunhu ari pedyo nemamiriro ezvinhu ari padyo nemuviri wemunhu zvakaoma chaizvo.

Zvechokwadi mamwe mafekitari anokurudzira kuisa rudzi urwu rwevhavha kumashure, iyo inogadzirisa dambudziko rekuoma kwekuvhara, asi zvino dambudziko rekuoma kwekuvhura mushure mekuvhara rinomuka. ‍

 

Yakakura dhayamita yemagetsi flange butterfly vharafu mugadziri Tianjin Zhongfa Valve-ZFA tekinoroji dhipatimendi kupedzisa, hombe dhayamita yemagetsi flange butterfly vharafu leakage zvikonzero zvine mamiriro akasiyana maererano neakasiyana masisitimu, pane zvikonzero zvakasiyana, zvinotevera kuongorora nyaya mbiri:

 

Chekutanga, nguva yekuvaka yakakonzerwa neyakakura dhayamita yemagetsi flange butterfly valve yemukati yekudonha zvikonzero: 

① kutakura uye kusimudza zvisina kufanira kukonzerwa nekukuvadzwa kwese kune yakakura dhayamita yegetsi flange butterfly vharafu, nekudaro zvichikonzera dhayamita yemagetsi flange butterfly valve kuvuza;

② fekitari, mushure mekumanikidza kwemvura kusatamba iyo yakakura dhayamita yemagetsi flange butterfly vharafu kuomeswa uye anticorrosion kurapwa, zvichikonzera kuumbwa kwemukati kuvuza kwechisimbiso pamusoro pekuora;

③ Kudzivirirwa kwenzvimbo yekuvaka hakusi munzvimbo, hombe yemagetsi flange butterfly vharafu haina kuisirwa kumativi ese mapofu, mvura, jecha uye zvimwe zvitsvina muchigaro chevharuvhu, zvichikonzera kuvuza;

④ Panguva yekuisa, hapana girisi inopinzwa muchigaro chevharuvhu, zvichiita kuti tsvina ipinde kumashure kwechigaro chevharuvhu, kana kupisa kunokonzerwa nekudonha kwemukati panguva yewelding;

⑤ Ivhavha haina kuiswa munzvimbo yakakwana yakazaruka, inokonzera kukanganisa kwebhora. Panguva yekuputika, kana vheji isiri munzvimbo yakazaruka zvakakwana, welding spatter inokonzera kukanganisa kubhora, uye kana bhora rine welding spatter richidzimwa uye richivharwa, rinowedzera kukanganisa kuchigaro chevhavha, zvichiita kuti kuvhare kwemukati;

⑥ Welding slag uye mamwe masara ekuvaka anokonzerwa nekuvharika kwepamusoro makwara;

fekitari kana nguva yekugadzika nzvimbo isina kurongeka inokonzerwa nekudonha, kana vharafu hunde kutyaira sleeve kana zvimwe zvishongedzo uye gungano pakona misalignment, hombe dhayamita yemagetsi flange butterfly vharafu inodonha.

 

Chechipiri, nguva yekushanda inokonzerwa nehukuru hukuru hwemagetsi flange butterfly valve leakage zvikonzero:

① Chikonzero chinowanzozivikanwa ndechekuti maneja wekushanda anofunga nezve kudhura kwekugadzirisa mari yedhayamita hombe yemagetsi flange butterfly valve haiiti kugadzirisa, kana kushaikwa kwesainzi yakakura dhayamita yemagetsi flange butterfly vharuvhu manejimendi uye nzira dzekuchengetedza dhayamita hombe yemagetsi flange butterfly vharafu haiite kudzivirira, zvichikonzera kutadza kwemidziyo pachine nguva;

② kushanda kusina kunaka kana kwete maererano nekugadzirisa maitiro ekugadzirisa kunokonzerwa nekubuda kwemukati;

③ Mukushanda kwakajairwa, zvisaririra zvekuvaka zvinokwenya nzvimbo yekuisa chisimbiso, zvichikonzera kudonha kwemukati;

④ Kucheneswa kwepombi kusina kunaka kunokonzeresa kukuvadzwa kunzvimbo yekuvharisa zvichikonzera kubuda kwemukati;

⑤ Kugara kwenguva refu kusingagadzirisi kana kusashanda kwehombe-diameter yemagetsi flange butterfly valve, zvichiita kuti chigaro chevharuvhu uye bhora ribate, zvichikonzera kuvharwa kwechisimbiso pakuchinja hombe-diameter yemagetsi flange butterfly valve kuti iite kudonha kwemukati;

⑥ hombe dhayamita yemagetsi flange butterfly vharafu vharafu haisi panzvimbo yekukonzera kudonha kwemukati, chero hombe dhayamita yemagetsi flange butterfly vharafu zvisinei nekuvhura nekuvhara chinzvimbo, kazhinji kurerekera 2 ° ~ 3 ° kunogona kukonzera kuvunza;

⑦ Mazhinji mahombe-diameter hombe-diameter emagetsi flange butterfly mavharuvhu mazhinji ane stem stop block, kana akashandiswa kwenguva yakareba, nekuda kwengura uye ngura uye zvimwe zvikonzero pakati pehunde uye stem stop block inounganidza ngura, guruva, pendi uye mamwe marara, marara aya anokonzeresa hombe-diameter yemagetsi flange butterfly inokonzera nzvimbo yegetsi-inotenderera-inotenderera-inotenderedza vharuvhu. flange shavishavi vharafu ari Kuvigwa, kurebesa vharafu hunde achabereka uye kuwa yakawanda ngura uye tsvina kutadzisa vharafu bhora kutenderera panzvimbo, zvichiita guru dhayamita yemagetsi flange butterfly vharafu leakage.

⑧ general actuator inogumirawo, kana iyo yenguva refu inokonzeresa ngura, kuomeswa kwegirisi kana kumisa mabhaudhi akasununguka achaita kuti muganho usave wakarurama, zvichikonzera kudonha kwemukati;

⑨ electric actuator valve position kumberi, isina hukama neinokonzeresa kudonha kwemukati;

⑩ kushaikwa kwekugadziriswa nekugadzirisa nguva nenguva, zvichikonzera kuvhara girisi yakaoma, yakaoma, yakaomeswa yekuisa chisimbiso girisi inoungana muchigaro chevharuvhu, ichitadzisa kufamba kwechigaro chevharuvhu, zvichikonzera kukundikana kwechisimbiso.

ZFA Valve Factory vane zvikwata zvehunyanzvi zveQC kuti ive nechokwadi chekuti vharafu yega yega yefekitori mukati uye kutaridzika kwakanaka. Panguva imwecheteyo, isu tine tekinoroji yehunyanzvi uye mushure mekutengesa zvikwata zvekubatsira vatengi kugadzirisa matambudziko akasiyana akasangana panguva yekuisa uye kushandiswa.
