Zvinhu uye Unyanzvi zvinodiwa zvevhavha Magetsi actuator yemagetsi chiteshi vharafu (1)
Chokutanga pane zvose, maererano nekusarudzwa kwevhavha, mumazuva ekutanga ekugadzwa kweSpecial Zone, mvura yepombi yemvura yakanga isingasviki makiromita gumi, uye yakawanda yepombi network yakashandisa mavharuvhu emagedhi. Nekuda kweiyo nyore pombi network uye kusimba kwakanaka kwemavharuvhu egedhi, basa remavharuvhu mupombi network rakanga risinganyanyi kukosha. Soft seal butterfly valve. Chisimbiso chepamusoro chinowanzogadzirwa nebutadiene rubber uye epDM rubber, etc. Reclaimed rubber inorambidzwa zvachose. Kuisa chisimbiso kunofanirwa kusangana nezvinodiwa zvehutano zviratidzo, uye kuratidza iyo anti-kuchembera bvunzo uye kupfeka kuramba bvunzo data;
Chokutanga pane zvose, maererano nekusarudzwa kwevhavha, mumazuva ekutanga ekugadzwa kweSpecial Zone, mvura yepombi yemvura yakanga isingasviki makiromita gumi, uye yakawanda yepombi network yakashandisa mavharuvhu emagedhi. Nekuda kweiyo nyore pombi network uye kusimba kwakanaka kwemavharuvhu egedhi, basa remavharuvhu mupombi network rakanga risinganyanyi kukosha. Uye mukutanga 1990s, kushandiswa shavishavi vharafu munyika yose nesimba, panguva iyoyo, China shavishavi vharuvhu kugadzirwa ichangotanga, mumuviri kukanda simba hakusi yakakwirira, vharafu ndiro apuroni chisimbiso kushanda kwakashata, kunaka kweshavishavi vharafu zvinetso zvakawanda. uye zviri pachena zvakafumurwa. Mavharuvhu anoshandiswa mupombi network akaiswa mumhando: gedhi vharafu rinoshandiswa kana DN≤400mm, butterfly valve inoshandiswa kana DN400mm. Nheyo huru yekuronga ndeyokuti 90% yebasa rekugadzirisa basa mupombi network inowanikwa mudiki-caliber pombi network pazasi DN400mm, saka inoda kusimba kwakanaka kwekuvhura nekuvhara mavharuvhu mupombi network. Uye nekuti iyo caliber idiki, kuwanda kwekushanda kwekuvhura nekuvhara kwevharuvhu hakuna kukura. Nekudaro, kuwanda kwepombi inoputika muDN400mm pombi network yakadzikira kupfuura iyo iri mudiki-caliber pombi network, uye kusimba kwekushanda kwekuvhura nekuvhara mushure mekushandisa butterfly valve kwakadzikira.
Dambudziko riripo muvhavha yekutenga inobatanidza kambani yedu zvakare inoisa pamberi inoenderana tekinoroji zvinodiwa:
1, vharafu zvinhu zvinodiwa
Muviri wevharuvhu uye ndiro yevharuvhu inofanira kugadzirwa ne ductile iron.
(2) hunde. Mavharuvhu egedhi achange ari hunde yesimbi isina tsvina (2Cr13), mavharuvhu eshavishavi achange ari masimbi asina tsvina;
Nut zvinhu. Inofanira kugadzirwa nendarira yealuminium yakakandwa kana yakakanda aluminium bronze, iyo kuoma kwayo uye simba zvakakura kudarika chivharo chevhavha;
Zvinhu zvekuisa chisimbiso pamusoro
A, common wedge gedhi vharafu. Mhete yendarira ichaumbwa nendarira yakanyungudutswa kana ndarira yakaumbwa nendarira;
B, soft seal butterfly valve. Chisimbiso chepamusoro chinowanzogadzirwa nebutadiene rubber uye epDM rubber, nezvimwewo. Rubber yakadzorerwa inorambidzwa zvachose. Kuisa chisimbiso kunofanirwa kusangana nezvinodiwa zvehutano zviratidzo, uye kuratidza iyo anti-kuchembera bvunzo uye kupfeka kuramba bvunzo data;
Valve shaft kurongedza. V rabha mhete kana kabhoni faibha impregnated polytetrafluoroethylene kurongedza, inofanira kuva nechokwadi chekuisa chisimbiso kuita kwakanaka, hapana kuvuza; Paunenge uchivhura nekuvhara kazhinji, kurongedza hakusi kushanda, kwete kuchembera, uye chisimbiso chinofanira kuchengetedzwa kwenguva yakareba, iyo inofanira kuvimbiswa kwemakore gumi kana kupfuura.
2. Zvido zveunyanzvi zvebhokisi rinokurumidza kufambisa bhokisi
Zvinhu zvemuviri zvinofanira kuenderana nemuviri wenyama;
(2) Bhokisi rekutumira rinofanirwa kuvharwa uye rinogona kumira kwete pasi pemamita matatu emvura yakadzika pasina kubuda;
(3) Mubhokisi hamuna masaramusi, uye girizi inofanira kushandiswa kudzivirira chikamu chiri pedyo chegiya.
3, yakapfava chisimbiso butterfly vharafu chimiro uye tekinoroji zvinodiwa:
(1) Ivhavha inofanira kuvharwa kutenderera kwewachi;
② Muviri wevharuvhu unofanirwa kupihwa butterfly plate limit block, simba rayo rinofanira kunge rakakura kudarika torque yekuvhura yevhavha;
Mhete yekuisa chisimbiso inofanira kuiswa pamutumbi wevharuvhu, uye chisimbiso chesimbi yekutsikirira ndiro inofanira kunge iri dovetail yekutsikirira ndiro ine yakavimbika anti-kusunungura matanho;
(4) vharafu kuvhura uye kuvhara kushanda kupera kunofanira kuva sikweya tenon, uye saizi yekumira, uye yakatarisana nepasi;
Mutsetse wechiyero chevhavha yekuvhura uye dhigirii rekuvhara unofanirwa kukandwa pachivharo chebhokisi regiya kana ganda rekuratidzira mushure menzira yekutendeuka, yunifomu yepamusoro, uye mutsara wechiyero unoputirwa nefluorescent poda kuratidza kubata ziso.
4, kuyerera kwemvura kuyerera muchikamu chemuviri wevharuvhu uye ndiro yevharuvhu inofanirwa kunge iri anticorrosive matanho, sekuchenesa jecha uye ngura yekupfapfaidza poda isiri-chepfu epoxy resin.
5, zvinodiwa zvezviratidzo zvevharuvhu
Kana iyo valve ichibva mufekitari, fekitari yevhavha inofanira kupa imwe yega nhamba yakatarwa, nhamba yayo uye muenzaniso wevhavhavha, caliber, nominal pressure, nhamba yevhavha, mugadziri, zuva rekugadzira uye mamwe mavara evhavha yevhavha inofanira kugadziriswa pamutumbi wevhavha.

3.1 yakayerwa torque Yakajairika Torque
Torque dhizaini yakapihwa kukosha.
3.2. Dzora torque inokanganisa torque
Munzira mbiri dzekuvhurika nekuvhara, iyo torque yekudzora meshini inogona kudzora torque renji kukosha, inozivikanwawo sekucheka torque.
Iyo torque yekudzora inogona kukamurwa kuita hombe yekudzora torque uye diki control torque. Zvineti hombe yekudzora torque ndiyo torque yekudzora meshini inogona kudzora yakakura kudzora torque ndiyo torque yekudzora michina inogona kudzora iyo shoma torque.
Torque yakakiyiwa
Torque inobuda nemagetsi actuator kana rotor yemota yakavharwa.
3. Seta torque yekuisa torque
Zvinoenderana nezvinodiwa nevashandisi, iyo torque kukosha inodzorwa nemagetsi actuator inogadziriswa isati yasvika.
3. 5. Kukurumidza kubuda

Inguva inodiwa nemagetsi actuator kuti amhanye kubva pa "full off" chinzvimbo kusvika pa "full on" chinzvimbo kana kubva pa "0%" sitiroko kuenda ku "100%" sitiroko.
Intrinsic kukanganisa
Pasi pemamiriro akatarwa ereferensi, musiyano mukuru pakati peiyo chaiyo sitiroko characteristic curve uye yakataurwa sitiroko characteristic curve inoratidzwa sechikamu cheyakayerwa sitiroko.
3. Hysteresis plus Dead band
Musiyano mukuru pakati pezviviri zvinoenderana nesitiroko yechiratidzo chimwechete chekuisa ichikwira uye ichidonha mukati meyero yakatarwa yesitiroko, inotaridzwa senge muzana yeyakayerwa sitiroko.
3.9 Bend yakafa
Nguva inogumira mukati meiyo shanduko munzira yechiratidzo chekupinza haikonzeri chero shanduko musitiroko, inoratidzwa senge muzana yechiratidzo chehuwandu hwechiratidzo.
3.10. Simba Kudzora Chikamu
Chigadzirwa chemagetsi chinoshandura nekukudza masaini emagetsi ekupinza kudzora matangiro, kumira uye kutenderera kwemota.
