Mhando uye misimboti yekushanda yehydraulic control valves:
1. Pfungwa ye hydraulic control valve: The hydraulic control valve ivhavha inotungamirirwa nemvura.Iyo ine vharafu huru uye yakasungirirwa conduit, pilot valve, tsono valve, bhora vharafu uye pressure geji.
2. Mhando dze hydraulic control valve: maererano nechinangwa, basa uye nzvimbo, inogona kuchinjwa kuva remote control float valve, pressure inoderedza valve, inononoka kuvhara cheki chekuvhara, kuyerera kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhare, mvura pombi yekudzora vharafu Mira.Zvinoenderana nechimiro, inogona kukamurwa kuita marudzi maviri: diaphragm mhando uye piston mhando.
3. Nheyo yekushanda yemhando ye diaphragm uye piston mhando yevhavha ye hydraulic control valve yakafanana.Ose ari maviri ari pamusoro pemvura yekumanikidza musiyano △P isimba, iro rinodzorwa nevharuvhu yekutyaira, kuitira kuti diaphragm (piston) hydraulic differential operation iite otomatiki.Gadzirisa, kuitira kuti guru revhavha disc rizarurwe zvachose kana kuvharwa zvachose kana mumamiriro ekugadzirisa.Kana mvura yekumanikidza ichipinda mukamuri yekudzora iri pamusoro pe diaphragm (piston) inoburitswa kumhepo kana kudzika kwakadzika nzvimbo yekumanikidza, kukosha kwekumanikidza kunoshanda pazasi pevhavha disc uye pazasi pe diaphragm yakakura kupfuura kukosha kwekumanikidza pamusoro, saka sundira. iyo huru yevhavha disc kuti ivhure zvizere Kana iyo yekumanikidza mvura ichipinda mukamuri yekudzora pamusoro pe diaphragm (piston) haigone kuburitswa kumhepo kana pasi pemvura yakadzika nzvimbo yekumanikidza, kukosha kwekumanikidza kunoshanda pa diaphragm (piston) yakakura kudarika kukosha kwepasi pasi. , saka guru revhavha disc Dhinda kunzvimbo yakavharwa zvakakwana;apo kudzvinyirirwa mukamuri yekutonga pamusoro pe diaphragm (piston) iri pakati pemhepo inopinza uye kubuda kwemhepo, iyo huru valve disc iri mumamiriro ekugadzirisa, uye nzvimbo yaro yekugadzirisa inoenderana nevhavha yetsono uye inogadziriswa mu catheter system Yakasanganiswa. kudzora basa revhavha yekutyaira.Iyo inogadziriswa yevhavhavhavhavhavha inogona kuvhura kana kuvhara yayo diki chiteshi chevharuvhu kuburikidza neiyo yakadzika yekubuda kudzvanywa uye kuchinja nayo, nekudaro ichishandura kukosha kwekumanikidza kwekamuri yekudzora pamusoro pe diaphragm (piston) uye kutonga chinzvimbo chekugadzirisa chesquare valve disc.
Kusarudzwa kwehydraulic control valve:
Iyo hydraulic control valve ivharuvhu inodzorwa nekumanikidza kwemvura.Iyo ine vharafu huru uye yakasungirirwa conduit, pilot valve, tsono valve, bhora vharafu uye pressure geji.
Paunenge uchishandisa hydraulic control valves, tanga wateerera kusarudzwa.Kusarudzwa kusina kunaka kunokonzera kuvhara kwemvura uye kubuda kwemhepo.Paunenge uchisarudza hydraulic control valve, unofanirwa kuwanza mashandisirwo emagetsi eawa neawa ne2-3 nguva yesarudzo reshiyo seyakanyanya condensate vhoriyamu kuti usarudze kubuda kwemvura yehydraulic control valve.Kuti uone kuti hydraulic control valve inogona kuburitsa mvura yakanyungudutswa nekukurumidza kana uchityaira, uye nekukurumidza kuwedzera tembiricha yemidziyo yekudziya.Kusakwana kwekuburitsa simba kweiyo hydraulic control valve kuchaita kuti condensate irege kuburitswa nenguva uye kuderedza kupisa kwekupisa kwemidziyo yekudziya.
Paunosarudza hydraulic control valve, iyo inonzi inonzi pressure haigoni kushandiswa kusarudza hydraulic control valve, nokuti iyo inonzi inodzvinyirira inogona kungoratidza kudzvinyirira kwe hydraulic control valve body shell, uye kudzvinyirirwa kwezita re hydraulic control valve yakasiyana zvikuru. kubva pakumanikidzwa kushanda.Nokudaro, kubviswa kwe hydraulic control valve kunofanira kusarudzwa maererano nekushanda kwekumanikidza kusiyana.Musiyano wekumanikidza wekushanda unoreva mutsauko uripo pakati pesimba rekushanda pamberi peiyo hydraulic control valve minus yekumashure kumanikidza pakubuda kwe hydraulic control valve.Kusarudzwa kwe hydraulic control valve kunoda kuvharika kwehuputi uye kudhiraivha, kunzwisiswa kwakanyanya, kuvandudza kushandiswa kweutsi, kusadonha kwemhepo, kushanda kwakavimbika kwekushanda, kukwira kumashure kwekumanikidza, hupenyu hurefu hwebasa, uye kugadzirisa kuri nyore.
Chero hydraulic control valve actuator chishandiso chinoshandisa simba kutyaira vharuvhu.Iri rudzi rwe hydraulic control valve device inogona kunge iri giya rinoshandiswa nemaoko, hydraulic control valve kushandura valve, kana chinhu chakangwara chemagetsi chine chigadziro chakaoma uye chekuyera, chinogona kushandiswa kubudirira kuenderera mberi kwekugadzirisa valve.Nekuvandudzwa kweiyo microelectronics tekinoroji, hydraulic control valve actuators yawedzera kuoma.Ekutanga actuators hapana chimwe kunze kwekufambiswa kwemotor giya ine chinzvimbo chekunzwa switch.Nhasi ma actuator ane mamwe mabasa epamberi.Iyo hydraulic control valve haigone kungovhura kana kuvhara vharafu, asi zvakare kuona mamiriro ekushanda evhavha uye actuator kuti ipe data rakasiyana-siyana rekufanotaura kuchengetedza.
Tsanangudzo yakakura kwazvo ye hydraulic control valve ye actuator ndeye: mudziyo wekutyaira unogona kupa linear kana rotary kufamba, iyo inoshandisa imwe simba rekutyaira uye inoshanda pasi peimwe chiratidzo chekudzora.
Iyo hydraulic control valve actuator inoshandisa mvura, gasi, magetsi kana mamwe masimba emagetsi uye inoishandura kuita basa rekutyaira kuburikidza nemota, silinda kana zvimwe zvishandiso.Iyo yakakosha actuator inoshandiswa kutyaira iyo hydraulic control valve kune yakavhurika zvizere kana yakavharwa zvizere chinzvimbo.
Hydraulic control valve installation:
Iyo hydraulic control valve ivharuvhu inodzorwa nekumanikidza kwemvura.Iyo hydraulic control valve ine vharafu huru uye yakasungirirwa conduit, pilot valve, tsono vharafu, bhora vharafu uye pressure geji.Zvinoenderana nechinangwa chekushandisa, basa uye nzvimbo, inogona kushandurwa kuita irimote control float valve, pressure reducer valve, inononoka kuvhara cheki cheki, flow control valve, pressure relief valve, hydraulic electric control valve, water pump control valve, etc.
Gadzirisa vharafu yakatwasuka papombi inopinza mvura, wozobatanidza pombi yekudzora, vharavhavhavha uye vharafu inoyangarara kuvharuvhu.Iyo vharafu inopinza pombi uye pombi yekubuda inobatanidza flange H142X-4T-A ndeye 0.6MPa yakajairika flange;H142X-10-A ndeye 1MPa yakajairika flange.Iyo dhayamita yepombi inopinza inofanira kunge yakakura kupfuura kana yakaenzana nedhayamita yezita revhavha, uye kubuda kunofanira kunge kwakaderera kupfuura vhavha inoyangarara.Ivhavha yekuyangarara inofanira kuiswa inopfuura mita imwe kubva papombi yemvura;chera kaburi mutangi remvura apo pombi yokubuda nayo inenge yakakwira kupfuura mwero wemvura kudzivirira mvura kuti isadzokere mumhepo.Paunenge uchishandiswa, valve yekuvhara inofanira kunge yakazaruka zvakakwana.Kana mavharuvhu anopfuura maviri akaiswa mudziva rimwe chete, mwero wakafanana unofanirwa kuchengetedzwa.Sezvo kuvharwa kwevharuvhu hombe kunosarira kuseri kwekuvhara kwevhavha yekuyangarara kweanenge 30-50 masekonzi, tangi remvura rinofanira kunge riine vhoriyamu yakasununguka yakakwana kudzivirira kufashukira.Kuti udzivise kusvibiswa uye zvimedu zvejecha kubva pakupinda muvhavha uye zvichikonzera kusashanda, sefa inofanira kuiswa pamberi pevhavha.Kana iyo yakaiswa mudziva repasi pevhu, mudziyo wearamu unofanirwa kuiswa mukamuri yepombi yepasi.
Sefa inofanira kuiswa pamberi pe hydraulic control valve, uye inofanira kuva nyore kudonha.
Iyo hydraulic control valve is self-lubricating valve body inoshandisa mvura uye haidi imwe lubrication.Kana zvikamu zvevhavha huru zvakakuvadzwa, tapota bvisai maererano nemirayiridzo inotevera.(Cherechedza: Kukuvadzwa kwakawanda muvharuvhu yemukati ndiyo diaphragm uye mhete yakatenderera, uye zvimwe zvikamu zvemukati hazviwanzo kukuvara)
1. Vhara mavharuvhu egedhi repamberi neshure evharuvhu huru kutanga.
2. Sunungura piping joint screw pachivharo chikuru chevharuvhu kuti ubudise kumanikidza muvharuvhu.
3. Bvisa zvisungo zvose, kusanganisira nati yepombi inodiwa yemhangura mupombi yekudzora.
4. Tora chivharo chevhavha uye chitubu.
5. Bvisa shaft core, diaphragm, piston, nezvimwewo, uye usakuvadza diaphragm.
6. Mushure mokubvisa zvinhu zviri pamusoro, tarisai kana diaphragm nemhete yedenderedzwa zvakuvadzwa;kana pasina kukanganisa, tapota usaparadzanisa zvikamu zvemukati iwe pachako.
7. Kana ukaona kuti diaphragm kana mhete yedenderedzwa yakakuvadzwa, tapota sunungura nut pane shaft core, disassemble diaphragm kana mhete zvishoma nezvishoma, uye wozoitsiva nediaphragm itsva kana mhete yedenderedzwa.
8. Tarisa zvakadzama kana chigaro chemukati chevhavha uye shaft core yevhavha huru yakakuvadzwa.Kana pane zvimwe zvakasiyana mukati mevharuvhu hombe, zvichenese kunze.
9. Unganidza zvikamu zvakatsiviwa uye zvikamu kuvharuvhu huru mune reverse order.Chenjerera kuti vharafu haifaniri kuvharwa.
