Kuiswa kwevhavha zvinodiwa simba chiteshi vharafu zvimiro zvakanakira uye tekinoroji yakatarwa
Valve iri mugadziriro yemvura, inoshandiswa kudzora kwainoenda mvura, kudzvanywa, kuyerera mudziyo, kugadzira pombi nemidziyo iri pakati (mvura, gasi, hupfu) kuyerera kana kumira uye inogona kudzora kuyerera kwemudziyo. Valve ndiyo inodzora chikamu chepombi yemvura inofambisa sisitimu, inoshandiswa kushandura chikamu chegwara uye yepakati kuyerera nzira, ine diversion, kucheka-kubvisa, throttling, cheki, shunt kana mafashama kudzvinyirira kunyaradza uye mamwe mabasa. Mavharuvhu ekudzora mvura anobva kumavharuvhu akareruka kusvika kune anoshandiswa muotomatiki akanyanya kuomarara masisitimu, ane akasiyana siyana emhando uye zvakatemwa, kubva mumazita emasaizi kubva kudiki zvakanyanya mavharuvhu epaipi mavharuvhu anosvika gumi. Inogona kushandiswa kudzora kuyerera kwemvura, chiutsi, mafuta, gasi, madhaka, marudzi ese ekuora media, simbi yemvura uye radioactive fluid uye mamwe marudzi emvura, vharafu inoshanda kumanikidza inogona kubva 0.0013mpa kusvika 1000MPa yakanyanya kudzvanywa, kushanda tembiricha. inogona c-270 ℃ kusvika 1430 ℃ yakakwirira tembiricha. Kudzora kwevharuvhu kunogona kushandisa akasiyana ekufambisa modhi, senge bhuku, magetsi, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, yemagetsi hydraulic, pneumatic, spur giya, bevel giya drive, nezvimwe .; Mukumanikidzwa, tembiricha kana imwe fomu pasi pechiito che sensor masaini, chiito, zvinoenderana nezvinodiwa zvekuchengetera kana kusatsamira pane sensor masaini ekuvhura kana kuvharika nyore, kuvimba nedhiraivha kana otomatiki nzira inoita yekuvhura nekuvhara valve ye kusimudza, kutsvedza, nzvimbo kana kutenderera kufamba, kuitira kuti uchinje saizi yechiteshi kuti uone basa rekutonga. Kuisa zvinodiwa 1, pamberi pekugadzwa kwevharuvhu, inofanirwa kunyatsotarisa iyo valve modhi, yakatarwa uye dhizaini; 2, maererano nemuenzaniso wevhavha uye mirayiridzo yefekitari kutarisa kana valve inogona kushandiswa mumamiriro ezvinhu anodiwa; 3. Paunenge uchisimudza chivharo, tambo inofanira kusungirirwa kune flange yekubatanidza muviri wevhavha uye chivharo chevhavha, uye kwete kusungirirwa kune handwheel kana tsinde, kuitira kuti irege kukuvadza tsvina uye handwheel; 4. Kana iyo valve yakaiswa pahorizontal pipeline, tsinde yevhavha inofanira kunge yakatarisa kumusoro, uye haibvumirwi kuiswa pasi; 5, paunenge uchiisa valve, usashandise iyo yekumanikidza pair yekubatanidza mode, kuitira kuti isakonzerese kukanganisa nekuda kwesimba risina kuenzana; 6, iyo stem gedhi vharafu haifanirwe kuiswa munzvimbo ine nyoro yepasi pevhu, kuitira kuti isaite ngura. Gungano rinodiwa zvikamu zvakachena zvinofanira kuvharwa kuti zvigadzirwe. Zvinodiwa zvekugadzwa ndezvizvi: 1. Mushopu wekuisa unofanirwa kuve wakachena, kana kumisa nzvimbo dzakachena kwenguva pfupi, senge richangotengwa jira remavara rine mavara kana firimu repurasitiki, kudzivirira huruva kupinda panguva yekuisa. 2, vashandi vegungano vanofanirwa kupfeka mbatya dzebasa dzedonje dzakachena, kupfeka chivharo chedonje chakachena, bvudzi harigone kubuda, tsoka dzinopfeka shangu dzakachena, maoko anopfeka magurovhosi epurasitiki, anobvisa mafuta. 3, maturusi egungano anofanirwa kucheneswa pamberi pegungano, kuve nechokwadi chakachena. Zvinodiwa Kugamuchirwa Kugamuchirwa kuri kuenderana neHG 20202-2000 Code yeKuvaka uye Kugamuchirwa kweDegreasing Engineering. Usati wasangana, pukuta chikamu chimwe nechimwe nebepa rakachena resefa, sarudza makona akafa ezvikamu, uye pepa resefa rine ruvara rusina kuchinjwa rinokodzera. 1, modhi yevharuvhu inofanirwa kuratidzwa zvinoenderana neNATIONAL chiyero chenhamba inoda. Kana iyo bhizinesi chiyero, inofanirwa kuratidza tsananguro yakakodzera yemuenzaniso. 2, iyo valve inoshanda kumanikidza, zvinodiwa ≥ pombi kushanda kumanikidza, pasina kukanganisa mutengo wenzvimbo, vharafu inogona kutakura kudzvanywa kunofanira kunge kwakakura kupfuura iyo chaiyo pombi kumanikidza. 3, mavharuvhu ekugadzira zviyero, anofanirwa kutsanangura hwaro hweNATIONAL chiyero nhamba, kana chiyero chebhizinesi, chibvumirano chekutenga chinofanira kusungirirwa kune gwaro rebhizinesi. Kuti uwane rumwe ruzivo, ndapota tarisa kune: Kuiswa zvinodiwa zvevhavha Chimiro Zvakanakira uye tekinoroji yemagetsi chiteshi vharafu "Simba chiteshi vharafu", inozivikanwawo semagetsi chiteshi vharafu, inonyanya kushanda kune pombi yeakasiyana masisitimu ezviteshi zvemagetsi zvinopisa, kucheka. kana kubatanidza pipeline media. Inoshanda svikiro: mvura, chiutsi uye imwe isiri-corrosive medium. Kuenzaniswa nezvimwe zvigadzirwa zvevharuvhu, magetsi echiteshi vharafu inoratidzirwa nekupisa kwakanyanya uye kudzvanywa kwepamusoro, yakasarudzika yekuzvisimbisa dhizaini, iyo yakanyanya kudzvanywa, iyo inonyanya kuvimbika yekuisa chisimbiso. Nekuda kwekuita kwakakosha, hunyanzvi hwekuita uye mamiriro ekushanda, chigadzirwa chakagadzira maitiro ayo zvimwe zvigadzirwa hazvigone kutsiviwa. Chigaro chevharuvhu uye disc sealing surface inogadzirwa necobalt-based carbide plasma spray welding, ine yakanaka abrasion resistance uye abrasion resistance.
