Dhizaini uye Kuita Maitiro eAmerican Standard Cast Steel Globe Mavharuvhu
Mumaindasitiri epombi masisitimu, maAmerican standard cast steel globe mavharuvhu anozivikanwa zvakanyanya nekuda kwekugara kwawo kwakanaka uye kuvimbika. Iri vharuvhu rakagadzirwa uye rakagadzirwa zvakanyatsoenderana nezvakatemwa neAmerican National Standards Institute (ANSI) uye American Petroleum Institute (API). Izvi zvinotevera zvinopa kuongororwa kwakadzama kwemaitiro ekugadzira eAmerican standard cast steel globe mavharuvhu uye maitiro ekuita aanotevera.
Design features
- Kusarudzwa kwezvinhu: American standard cast steel globe mavharuvhu anowanzo kukandwa achishandisa ASTM yakatarwa simbi, senge ASTM A126 giredhi WCB (carbon steel castings), kuve nechokwadi chekuti vharafu ine yakanaka mechanical simba uye corrosion resistance.
- Dhizaini yekuisa chisimbiso: Chigaro chevharuvhu uye disc zvakagadzirirwa zvakanyatsoenderana neconical kana denderedzwa yekuisa chisimbiso nzvimbo kuti ive nechokwadi chekudzivirira kunoshanda kwepakati kuvuza munzvimbo yakavharwa uye kuwana yakasimba yekuvhara mhedzisiro.
- Valve stem anti blowout dhizaini: Kudzivirira hunde yevharuvhu kuti isaputirwe nepakati panguva yekushanda-kudzvanywa kwepamusoro, iyo American standard cast steel globe valve yakagadzirwa ine anti blowout mudziyo, inovandudza kuchengetedzeka kwevharuvhu.
- Dhizaini yekuchengetedza moto: Zvinoenderana neiyo API 607 chiyero chekuchengetedza moto, mamwe maAmerican standard cast steel globe mavharuvhu akagadzirwa ane zvimiro zvinodzivirira moto, izvo zvinogona kuchengetedza imwe yekuisa chisimbiso kunyangwe pakaitika moto, kuve nechokwadi chekuchengetedzwa kwehurongwa.
- Valve stem seal: Iyo inotsiviwa valve stem seal chikamu chinoshandiswa, iyo inovimbisa kuderera kwakadzika panguva yekuvhura nekuvhara, uye zvakare iri nyore kuchengetedza uye kutsiva.
- Handwheel operation: Kuti zvive nyore kushanda kwemaoko, American standard cast steel globe mavharuvhu anowanzo kuve ane vhiri reruoko, uye saizi uye simba dhizaini reruoko rinosangana nezvinodiwa neANSI kuti ishandiswe nyore nemushandisi.
Maitiro ekuita
- Chiyero chekumanikidza: American standard cast steel globe mavharuvhu akaiswa zvinoenderana neakakodzera zviyero se ANSI/ASME B16.34, seKirasi 150 uye Kirasi 300, kuve nechokwadi chekushanda kwakachengeteka pasi pekumanikidzwa kwakasiyana.
- Tembiricha renji: Zvinoenderana nekushisa kwemhando yeASTM zvinhu, American standard cast iron globe mavharuvhu akakodzera kune akasiyana nharaunda yekushanda kubva pasi kusvika kune yakakwirira tembiricha.
- Leakage level: Zvinoenderana neiyo leakage standard yeFCI-70-2 (Factory Mutual Research), American standard cast iron globe mavharuvhu anopa akasiyana mazinga ekuisa chisimbiso kusangana neakasiyana maindasitiri ekushandisa.
- Material corrosion resistance: Iko kuumbwa kwemakemikari uye kupisa kwekupisa kwechinhu kunoenderana nemitemo yeASTM, kuve nechokwadi chokuti vheji inogona kuramba ichichengetedza kunaka kwekuora mumidhiya inoparadza.
- Chigadzirwa Certification: American standard cast steel globe mavharuvhu anowanzoda akatevedzana echigadzirwa certification, kusanganisira kumanikidzwa kuyedzwa, kuyedza kuita basa, uye kuyedza kuramba moto, kuratidza kuti vanozadzisa zvinodiwa mazinga akakodzera.
Muchidimbu, maAmerican standard cast steel globe mavharuvhu anotarisa pakuita uye kuchengetedzeka mukugadzira kwawo, uye anogadzirwa akanyatsoenderana neAmerican yenyika zviyero uye indasitiri tsika kuti ive nechokwadi chekuita kwakagadzikana pasi pemamiriro ekushanda akanyanya. Zvingave muminda yepetroleum, makemikari, gasi rechisikigo, kana mamwe maindasitiri, American standard cast steel globe mavharuvhu aratidza kushanda kwawo kwepamusoro uye kuvimbika kwakanyanya. Pakusarudza mavharuvhu akadaro, vashandisi vanofanira kunyatsoongorora zviyero zvavanosangana nazvo uye chaiyo yenzvimbo yekushanda zvinodiwa kuti vave nechokwadi chekururama kwekusarudzwa uye kushanda kwakachengeteka uye kwakagadzikana kwegadziriro.
