Ndinokwanisa here kusuma kuita kwekuisa chisimbiso uye kuona kubuda kwemvura?

Plastiki butterfly vharafu chinhu chinowanzo shandiswa mvura yekudzora midziyo ine zvakanakira chimiro chakareruka, huremu huremu uye nyore kuisa. Inoshandiswa zvakanyanya mukugadzira maindasitiri uye pombi masisitimu, asi yekuisa chisimbiso uye matambudziko ekudonha kwave kuri kutarisisa.

iyo yekuisa chisimbiso uye kuona kuvuza kwepurasitiki butterfly valves ichaunzwa zvakadzama:

1, kuita chisimbiso kwepurasitiki butterfly valve

Kuisa chisimbiso kweplastic butterfly valve kunonyanya kusanganisira zvinhu zviviri: static sealing uye dynamic kuvharika.

Static Seal kugona

Static tightness zvinoreva kuti hapana kuvuza pakati pemuviri wevharuvhu nenzvimbo yakavharika kana vharafu repurasitiki rinenge rakavharwa. Zvikamu zvikuru zvekuisa chisimbiso zvepurasitiki butterfly valve zvinosanganisira chigaro chevharuvhu, ndiro yevharuvhu uye mhete yekuisa chisimbiso. Nzvimbo dzekuvharisa dzechigaro chevharuvhu neplate yevharuvhu dzinowanzo gadzirwa nezvinhu zvakaita serabha kana PTFE, zvine kuita kwakanaka kwekuvhara. Mhete yekuisa chisimbiso inoita basa rekuvhara, inogona kugadzirwa nerabha ring, PTFE ring uye zvimwe zvinhu. Mukugadzira uye kugadzira maitiro, zvinodikanwa kuti ive nechokwadi chekudzikama, kutenderera uye kurongeka kwakaringana kwenzvimbo yekuisa chisimbiso kuti ive nechokwadi chekuisa chisimbiso kuita.

Dynamic sealing

Dynamic sealing inoreva vharuvhu yeshavishavi repurasitiki pakuvhura nekuvhara, hapana kuvuza pakati pemuviri wevharuvhu nenzvimbo yakavharika. Kuvharika kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhashanainya kunoenderana nekunamwa kwehunde yevharuvhu uye kurongedza. Iko kupokana pakati pehunde yevharuvhu nekurongedza ndiyo kiyi yekudzivirira kubuda. Zvinhu zvakadai sepolytetrafluoroethylene kurongedza uye flexible graphite packing zvinowanzo shandiswa sechisimbiso chekuisa chisimbiso, icho chine kunaka kwekudzivirira kusvibiswa uye kupisa kwakanyanya. Panguva yekushanda, kurongedza kunoda kuongororwa nguva nenguva kuti kusakara uye kubvaruka, uye kuchengetedzwa nekutsiviwa kuti ive nechokwadi chekuisa chisimbiso kuita.

2, iyo yepurasitiki butterfly vharafu inobuda

Plastic butterfly valve leakage yekuona ndeye kuona kushanda kwakajairwa kwevhavha uye kudzivirira tsaona yekudonha chinhu chakakosha chinongedzo.

Kuonekwa kwechitarisiko

Kuonekwa kwechitarisiko kunonyanya kuburikidza nekutarisa kwekuona, tarisa kana muviri wevharuvhu, tsinde yevharuvhu, kurongedza uye zvimwe zvikamu zvine kupfeka kuri pachena, kutsemuka kana deformation. Panguva imwecheteyo, zvinodiwawo kutarisa kana nzvimbo yekuisa chisimbiso ine tsvina, zvinhu zvekunze uye zvimwe zvinokanganisa kuvepo kwekuiswa chisimbiso.

Airtightness test

Gasi tightness kuyedzwa kunogona kuitwa uchishandisa gasi tightness tester. Icho chiridzwa chinowanzo shandisa imwe chiyero chekumanikidza kuvharuvhu uye yobva yaona kana kune chero gasi kubuda. Kana paine kuvuza, nzvimbo dzekuisa chisimbiso uye kurongedza dzinoda kutariswa kushanda kwayo, kuchengetedzwa uye kugadziriswa.

Liquid Tightness Testing

Liquid-kusimba kuyedzwa kunogona kuitwa uchishandisa mvura-kusimba tester. Ichi chiridzwa chinowanzo shandisa imwe dzvinyiriro kuvharuvhu yobva yaona kana paine mvura inobuda. Kana paine kuvuza, nzvimbo yekuisa chisimbiso uye kurongedza inoda kuongororwa kushanda kwayo, uye kugadzirisa uye kugadzirisa kunofanirwa kuitwa.

Sonic Detection

Acoustic wave yekuona inzira inokurumidza uye yakarurama yekuona kuvuza. Kuburikidza nekushandiswa kweacoustic wave yekuona zviridzwa, mutsindo unogadzirwa kana vharafu ichidonha ichigona kuwonekwa, uye kusimba uye kuwanda kweruzha kunogona kushandiswa kuona huwandu uye nzvimbo yekudonha.

Muchidimbu, kuiswa chisimbiso uye kudonha kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha kiyi yekiyi yekuona kushanda kwakajairwa uye kushandiswa kwakachengeteka kwevharuvhu. Mukati mekugadzira, kugadzira uye kushandisa, zvinofanirwa kutarisisa kusarudzwa kwezvinhu zvakakodzera zvekuisa chisimbiso, kudzora kwakasimba kwezvinodiwa maitiro, uye nguva dzose yekuona kuvuza uye basa rekugadzirisa kuti ive nechokwadi chekuchengetedza uye kuvimbika kwepurasitiki butterfly valves.
