New Welded Two-Piece Ball Valve Applications for High Temp, High Pressure Environments

1. Nhanganyaya

Mavharuvhu midziyo yakakosha inoshandiswa kudzora kuyerera kwemvura, kudzvanywa uye kuyerera kwegwara mumasitimu ekuunza mvura. Izvo zvinoshandiswa zvakanyanya mu petroleum, makemikari, magetsi emagetsi, metallurgy uye mamwe maindasitiri. Munzvimbo dzekushisa uye nepamusoro-soro, mavharuvhu anodiwa kuti ave nezvinodiwa zvakanyanya, kwete chete kuti ave nekuita kwakanaka kwekuvhara, asiwo anoda kuti ave nekushisa kwepamusoro uye kusagadzikana kwekudzivirira. Sevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhava rakasungwa rave richishandiswa zvakanyanya mumunda wekupisa kwepamusoro uye kudzvinyirirwa kwepamusoro nekuda kwechimiro chayo chakasiyana-siyana chekugadzira uye kushanda kwepamusoro.

2. Mamiriro ezvinhu e-welded maviri-chidimbu bhora mavharuvhu

2.1. Chimiro chakareruka: Iyo yakasungwa maviri-chidimbu bhora vharafu inonyanya kuumbwa nevharuvhu muviri, bhora, chigaro chevharuvhu, tsinde yevharuvhu, mhete yekuisa chisimbiso uye zvimwe zvikamu. Iine chimiro chakareruka, uremu huremu, uye iri nyore kuisa nekuchengetedza.

2.2. Kuita kwakanaka kwekuisa chisimbiso: Bhora nechigaro chevharuvhu zvinotora chisimbiso chechiso, chine nzvimbo yakakura yekuisa chisimbiso uye kuita kwakanaka kwekuisa chisimbiso, iyo inogona kusangana nekuisa chisimbiso pasi pekushisa kwepamusoro uye kudzvanywa kwenzvimbo.

2.3. Kurumidza kuvhura uye kuvhara kumhanya: Iyo yakashongedzerwa-zvidimbu zviviri bhora vharafu inotora 90 ° kutenderera kwebhora kuti iwane kuvhura nekuvhara, nekukurumidza kuvhura nekuvhara nekukurumidza uye nyore kushanda.

2.4. Diki kuyerera kupikisa: Iyo bhora chiteshi chakagadzirwa nedhayamita yakazara, kuyerera kudiki kuramba, yakakura kuyerera kugona, uye inogona kuderedza kushandiswa kwesimba kwehurongwa.

2.5. Tembiricha yakanaka uye kumanikidza kuramba: Iyo yakasungwa maviri-chidimbu bhora vharafu inogadzirwa nezvinhu zvakakosha, ine yakanakisa tembiricha uye kudzvinyirira kuramba, uye inokodzera tembiricha yepamusoro uye yakanyanya kudzvanywa nharaunda.

2.6. Yakasiyana-siyana madhiraivha modhi: bhuku, magetsi, pneumatic, hydraulic uye mamwe madhiraivha modhi anogona kusarudzwa zvinoenderana nezvinodiwa chaizvo.

3. Mamiriro ekushandisa eakasungwa maviri-chidimbu bhora mavharuvhu mu tembiricha yepamusoro uye yakanyanya kudzvanywa nharaunda

3.1. Petrochemical industry

Muchikamu chekunatsa chebhizimusi repetrochemical, tembiricha yepakati yakakwira kusvika 400 ℃ uye kudzvanywa kunosvika 10MPa. Muchigadzirwa ichi, yakasungwa maviri-chidimbu bhora vharafu inoshandiswa sechinhu chakakosha chekudzora kuyerera kwemvura uye kumanikidza. Mushure memakore ekushanda, vheji yebhora yakaratidza kushanda kwakanaka kwekuvhara uye kutonhora uye kusagadzikana kwekudzivirira, kuve nechokwadi chekushanda kwakagadzikana kwechigadzirwa.

3.2. Indasitiri yemagetsi

Mune boiler yekudyisa mvura system yemagetsi ekupisa, tembiricha yepakati i320 ℃ uye kudzvanywa kuri 25MPa. Mune iyi sisitimu, yakasungwa maviri-chidimbu bhora vharafu inoshandiswa seyakachekwa-kubvisa uye kudzora mudziyo. Mukushanda chaiko, vharuvhu yebhora inoratidza maitiro ekukurumidza kuvhura uye kuvhara kukurumidza, kuita kwakanaka kwekuvhara, uye yakanakisa tembiricha uye kudzvinyirira kuramba, ichipa chivimbiso chakasimba chekuchengetedza uye kugadzikana kushanda kwemagetsi ekupisa.

3.3. Metallurgical industry

Mumutsara wekugadzira wesimbi wesimbi, tembiricha yepakati i600 ℃ uye kudzvanywa kuri 15MPa. Mumutsara uyu wekugadzira, vheji yebhora yakasungwa maviri-chidimbu inoshandiswa sechinhu chepakati chekudzora. Ivhavhavha yebhora inoratidza kushanda kwakanaka pasi pekushisa kwepamusoro uye kudzvinyirira kwakanyanya, kusangana nezvinodiwa zvekugadzira zvemutsara wekugadzira.

4. Chengetedzo yekushandiswa kweakasungwa maviri-chidimbu bhora mavharuvhu mu tembiricha yepamusoro uye yakanyanya kudzvanywa nharaunda.

4.1. Sarudza zvinhu zvakakodzera: Maererano nekushisa kwekushanda kwekushanda uye kudzvinyirira, sarudza zvinhu zvine kutonhora kwakanyanya uye kusagadzikana kwekudzivirira kuti uve nechokwadi chehupenyu hwebasa revhavha yebhora mukupisa kwepamusoro uye nzvimbo dzakamanikidzika.

4.2. Yakasimba yekuisa chisimbiso dhizaini: Kuisa chisimbiso dhizaini ndiyo kiyi yewelded maviri-chidimbu bhora mavharuvhu. Zvinhu zvakakodzera zvekuisa chisimbiso zvinofanirwa kusarudzwa kuti ive nechokwadi chekuisa chisimbiso chevhavha yebhora mukupisa kwepamusoro uye nzvimbo dzekumanikidza.

4.3. Gadzirisa modhi yekutyaira: Zvinoenderana nezvinodiwa chaizvo, sarudza yakakodzera dhiraivha modhi yekuvandudza mashandiro ekushanda uye otomatiki yevhavha yebhora.

4.4. Kugara uchiongorora uye kugadzirisa: Pasi pekushisa kwepamusoro uye nzvimbo yakakwirira yekumanikidza, kushanda kwechisimbiso uye kutonhora uye kusagadzikana kwekudzivirira kwevhavha yebhola kunokanganisa nyore nyore. Nokudaro, valve yebhora inofanira kuongororwa uye kuchengetwa nguva dzose kuti ive nechokwadi chekushanda kwayo.

4.5. Vadzidzisi vezvitima: Simbisai kudzidziswa kwevashandi, kuvandudza unyanzvi hwavo hwekushanda, uye kuderedza kukundikana kwevhavha yebhora kunokonzerwa nekushanda kusina kunaka.

Iyo welded-t-piece ball valve ine yakanakisa application performance pasi pekushisa kwepamusoro uye kudzvanywa kwenzvimbo, ichipa vimbiso yakasimba yepetroleum, kemikari, simba remagetsi, simbi uye mamwe maindasitiri. Mukushandiswa chaiko, zvinhu zvakakodzera zvinofanirwa kusarudzwa zvinoenderana nemamiriro chaiwo ekushanda, dhizaini yekuisa chisimbiso, yakagadziridzwa drive mode, kuongororwa uye kugadzirisa nguva dzose, uye kudzidziswa kwevashandi kunofanirwa kusimbiswa kuti ive nechokwadi chekuchengetedza uye kugadzikana kushanda kwevhavha yebhora pasi pekupisa kwakanyanya uye yakakwirira. pressure environment. Nekuenderera mberi kwekuvandudza tekinoroji yeindasitiri, iyo welded-piece ball valve ichaita basa rakakosha mune mamwe minda.
