Actuating valve chiito nzira, self-actuating uye kunze simba. Kuzvimirira kunoreva chimiro chemukati chevharuvhu chinoumbwa nekushandurwa kwezvinhu zvinomanikidza kushanda, tembiricha uye mamwe masimba ekutyaira iyo yepakati pevhavha zvinhu zvakasiyana zvinofamba; Kutyaira kwekunze kwesimba kunoreva kushandiswa kwesimba rekunze kutyaira zvakasiyana-siyana zvinofamba zvemukati wevharuvhu, zvinosanganisira bhuku, magetsi, pneumatic, hydraulic control valve, electromagnetic induction drive uye idzi nzira dzekutyaira dzinodyidzana. Ivharuvhu isingaite inosanganisa kuvharika kusingaite, chimiro chisingashande, kusashanda zvakanaka, zvichingodaro. Kusimba kusingaite kunosanganisira kuratidzwa uye kubuda kwemhepo. Chimiro chisina kukodzera chinosanganisira kutadza kwekutyaira, chigaro chakanamira, spool yakafa, nezvimwe. Kutadza kushanda zvinoenderana nerudzi rwevharuvhu kwakasiyana…

Iyi chiyero inotsanangura zvakajairwa kuisirwa, kushandisa uye kugadzirisa kwemaindasitiri esimbi mavharuvhu.
Izvi zvinoshanda kumavharuvhu eglobhu, mavharuvhu epasi, mavharuvhu okuyamura, mavharuvhu egedhi, mavharuvhu edhisiki, mavharuvhu epneumatic butterfly, mavharuvhu epuragi, mavharuvhu echeki, mavharuvhu, mavharuvhu anodzora, mavharuvhu echitsinga, mavharuvhu ekudzora uye mamwe mavharuvhu.
2 Normative reference zvinyorwa
Izvo zvinopihwa mumagwaro anotevera zvinova zvipimo zvinoenderana zveChiratidzo ichi maererano nekuunzwa kweichi chirevo. Kana gwaro rakanyorwa, imwe neimwe inotevera shanduko (isina erratum) kana kudzokorora haina kukodzera kune iyi rondedzero. Zvakadaro, kana gwaro risina kunyorwa zuva, nhamba yevhezheni yenhamba yeshanduro ichashanda kune zvakatemwa kukurudzira tsvakiridzo dzakasiyana siyana dzesainzi kuti dzisvike pakubvumirana kuti ruzivo rwegwaro rungashandiswa here.

Valve tip uye pombi kana midziyo yekuwana fomu, kusanganisira looper flange, flange yekubatanidza, threaded connection, groove connection, nezvimwe.
kutyaira nzira yekutyaira mamics
Actuating valve chiito nzira, self-actuating uye kunze simba. Kuzvimirira kunoreva chimiro chemukati chevharuvhu chinoumbwa nekushandurwa kwezvinhu zvinomanikidza kushanda, tembiricha uye mamwe masimba ekutyaira iyo yepakati pevhavha zvinhu zvakasiyana zvinofamba; Kutyaira kwekunze kwesimba kunoreva kushandiswa kwesimba rekunze kutyaira zvakasiyana-siyana zvinofamba zvemukati wevharuvhu, zvinosanganisira bhuku, magetsi, pneumatic, hydraulic control valve, electromagnetic induction drive uye idzi nzira dzekutyaira dzinodyidzana.
3.3 Style basa kubasa
Valve yekushanda maitiro inosanganisira yakavhurika uye yakavharika, kazhinji yakavharwa, pfupi-nguva yekushanda sisitimu, inoenderera yekushanda sisitimu, inopindirana kutenderera nguva yekushanda system.
3.4 kukundikana kwevhavhavhavha kukundikana
Kukundikana kwevharuvhu kunosanganisira kukundikana kwechisimbiso, kutadza kumira, kusashanda zvakanaka, nezvimwewo. Chimiro chisina kukodzera chinosanganisira kutadza kwekutyaira, chigaro chakanamatira, spool yakafa, etc. Kukundikana kwekushanda kunosiyana maererano nemhando dzakasiyana-siyana dzevhavha, dzakadai sekugadzirisa vharafu zvisina kunaka, kusunungura kudzvinyirira kushanda kudzvinyirira kusagadzikana, valve kwete maererano nezvigadziro zvekushanda kwekumanikidza bounce.
4 Kuiswa
4.1 Kugadzirira Kuiswa
4.1.1 Usati waiswa vharuvhu, tarisa kuti chitupa chekukodzera chigadzirwa uye kuisirwa nekushandisa bhuku rekushandisa revharuvhu rakazara uye rinoshanda.
4.1.2 Kuongororwa kwechitarisiko kuchaitwa pamberi pekuisa vharafu, iyo ichaenderana nezvinotevera:
a) Nzvimbo yacho haifanire kuve nekutsemuka, maburi ejecha, kukuvara kwemuchina, ngura, mavara uye kumwe kukanganisa;
b) Iyo fekitori nameplate haizodonha, uye maparamita ekuita mufekitori nameplate anowirirana neakakosha mapoinzi ekugadzira system;
c) Mativi maviri evhavha anofanirwa kuchengetedzwa nevhavha yekudzivirira.
d) Panofanira kunge pasina kuchengetedza mvura, ngura, mavara uye kukuvadza mubhodhi redunhu remafuta;
e) Pachave pasina pendi pane iyo flange yakabatana screw, screw ichave yakasimba, iyo yekuvharisa pamusoro peflange haizokuvadzwa neaxial pipe groove nezvimwe zvinhu, uye welding yemagetsi welding ichave yakasimba, uye pachava usave newelding mechanical kukuvara;
f) chitubu chekuchengetedza vharafu kutarisa kuvimbika kwechisimbiso. Rombo yemhando vharafu inofanira kuva inorema sando mhando yekuisa midziyo;
g) Nzvimbo yemukati yemuviri wepipe yakavharwa yerabha, dziva rine porcelain uye plastiki yakavharidzirwa valve inofanira kuva yakatsetseka, jira uye nheyo yezvinhu zvinofanira kubatanidzwa zvakasimba, pasina kuputika, kuputika uye zvimwe zvikanganiso.
4.1.3 Valvha kuvhura uye kuvhara kuongorora uye kumanikidza bvunzo
Vhuru (kunze kwevharuvhu) switch inofanirwa kuve inonzwisisika, chinzvimbo chiratidzo chakarurama. Usati waiswa, shandura nemaoko simba revhavha katatu kuti uone kana pane mamiriro akanamatira.
Iyo valve (kunze kwevhavha) ichasiiwa fekitori kwerinopfuura gore, uye inokurudzirwa kuita bvunzo yekumanikidza pasi pemamiriro. Muedzo wevharuvhu weindasitiri yepetrochemical uye minda inoenderana ichaitwa zvinoenderana nezvinodiwa zveJB/T 9092, uye bvunzo yevharuvhu yeindasitiri ichaitwa zvinoenderana nezvinodiwa zveGB/T 13927.
4.2 Kuiswa
4.2.1 General Zvinodiwa
4.2.1.1 Verenga bhuku rekuisa zvakanaka usati waisa valve.
4.2.1.2 Mavharuvhu akatarwa kuti apinde achaiswa zvinoenderana nezvinodiwa nevharuvhu.
4.2.1.3 Kazhinji, chirungiso chevharuvhu hachifanirwe kuisirwa pasi kudzivirira chigaro kuti chisabatike.
4.2.1.4 Kusimudza cheki chekivhavha inofanira kunge yakasimwa, swing check valve shaft sleeve inofanira kuva yakaenzana.
4.2.1.5 Pane vharuvhu yekudzivirira yekudzivirira, uye vheji yekuburitsa inofanira kunge iine pombi yekubuda, uye kuburitsa kutaridzika hakufanirwe kutarisana nemushandisi.
4.2.1.6 Nzvimbo yekuisa valve inofanira kuva yakanakira kushanda uye kugadzirisa.
Iyo actuating mechanic inonamira nekuda kwekuora kwekabhoni simbi torsion chitubu mukushandisa yega-inoshanda tembiricha inodzora vharafu. Dambudziko rakagadziriswa nekushandura chitubu chetorsion kuita simbi isina tsvina. (4) Pamapaipi anenge aiswa pakushandisa zvishoma, zvimwe zvikamu zvakanamira nekuti mavharuvhu anozvishanda ega haashande kwenguva yakareba. Nekuita nguva dzose kugadzirisa uye kuenzanisa kwevhavha, mukana wekukundikana kwakajairika kunoderedzwa.
Self - inoshandiswa tembiricha yekudzora vharafu application mamiriro
Kuzvimiririra tembiricha yekudzora vharafu kiyi yekugadzirisa tekinoroji
(1) Tembiricha inozvidzora vharafu (tembiricha inonzwa nzvimbo yemukati chimiro) yekupisa yekupisa inopinza uye yekubuda tembiricha kutonga.
(2) Temperature self-regulating valve (capillary yekunze tembiricha inonzwa nzvimbo) yekupisa exchanger inopinza uye yekubuda tembiricha kutonga.
2. Matambudziko ekushandisa akaitika
(1) Spool yanamira;
(2) Ivhavha haigoni kuvhurwa;
(3) inodziya capillaries dehysis;
(4) The actuator yakanamira;
(5) Chimiro chemukati che actuator chakasvibiswa mushure me condensate;
(6) Iyo ketani diki ye actuator haigone kubuda kunze mushure mekuvharwa;
(7) Kubuda kwevharuvhu kwakakura.
3 Kuchengetedza uye kugadzirisa matanho
(1) Pamberi pekuongorora kwakakodzera kwegore, mukana wekukundikana kwakajairika wakakura kwazvo. Yakawedzera mukana wakakwana wekuongorora kwegore rino. Zvinyorwa zvekuongorora kwegore rino ndezvi: tarisa kana pane dambudziko nekugadzirisa hurongwa, manually gadzirisa kutonhora, kuti uone kana pane nzvimbo inopindirana yevhavha yekugadzirisa; Tarisa uone kubuda kwecapillary.
(2) Nekuda kwekusarudzwa kwehuputi glue kuita kupisa kupisa, zvichikonzera foam glue muvharuvhu, kuitira kuti vharafu inonamira. Mushure mekushandura nzira yekudzivirira kupisa, dambudziko iri rinogadziriswa nenguva.
(3) Iyo actuator yakanamira nekuda kwekuora kwekabhoni simbi torsion chitubu. Dambudziko rakagadziriswa nekushandura chitubu chetorsion kuita simbi isina tsvina.
(4) Pamapaipi anenge aiswa pakushandisa zvishoma, zvimwe zvikamu zvakanamira nekuti mavharuvhu anozvishanda ega haashande kwenguva yakareba. Nguva dzose kuchengetedza uye kuenzanisa kunoitwa kuti valve ideredze mikana yekukundikana kwakajairika.
