Ball valve, nhengo yekuzarura nekuvhara (bhora) inotungamirirwa nevhavha yevhavha uye inotenderera kumativi ose evhavha yebhora.Inogonawo kushandiswa kugadzirisa mvura uye kutonga.Pakati pavo, iyo yakaoma-yakavharwa V-yakaita bhora vharafu ine simba rakasimba rekugera pakati peV-yakaita bhora core uye simbi yevharuvhu chigaro che hard alloy surfacing, iyo inonyanya kukodzera kune fiber uye diki diki diki.etc. pakati.Iyo yakawanda-port bhora vharafu papombi haingogone chete kudzora confluence, diversion, uye switching yekuyerera kwepakati, asi zvakare inogona kuvhara chero chiteshi uye kubatanidza mamwe maviri chiteshi.Rudzi urwu rwevharuvhu kazhinji runofanira kuisirwa yakatwasuka mupombi.Ivhavha yebhora yakakamurwa kuva: pneumatic ball valve, electric ball valve, manual ball valve maererano nenzira yekutyaira.

Ball valve features:

1. Kusapfeka;nekuti iyo yepakati yevharuvhu yakavharwa-yakavharwa bhora vharafu ndeye alloy simbi yekupfapfaidza welding,

Mhete yekuisa chisimbiso inogadzirwa nealloy simbi yakatarisana, saka iyo yakaoma-yakavharwa bhora vharuvhu haiburitse yakawandisa kupfeka kana ichibatidzwa nekudzimwa.(Kuoma kwayo chinhu 65-70):

Chechipiri, kuiswa chisimbiso kwakanaka;nokuti kuiswa chisimbiso kwevhavha yebhora yakaoma-yakavharwa yakaitwa pasi, haigoni kushandiswa kusvikira nheyo yevhavha uye mhete yekuisa chisimbiso ichifananidzwa.Saka kuisa kwake chisimbiso kwakavimbika.

Chechitatu, chinja chiedza;nokuti pasi pechisimbiso chevhavhavha yakavharwa-yakavharwa inotora chitubu kuti ibate mhete yekuisa chisimbiso uye nheyo yevhavha yakasimba pamwe chete, kushandura kwakanyatsojeka kana simba rekunze rinopfuura preload yechitubu.

4. Hupenyu hurefu hwebasa: Yakashandiswa zvakanyanya mupetroleum, indasitiri yemakemikari, kugadzirwa kwemagetsi, kugadzira mapepa, simba reatomu, ndege, roketi uye mamwe madhipatimendi, pamwe nehupenyu hwevanhu zuva nezuva.

Iyo pneumatic ball valve ine yakapusa uye compact chimiro, yakavimbika chisimbiso uye nyore kugadzirisa.Iyo yekuisa chisimbiso uye spherical surface inogara iri munzvimbo yakavharwa, iyo isiri nyore kuparadzwa nepakati, uye iri nyore kushanda nekuchengetedza.Iyo yakakodzera kune yakajairwa inoshanda midhiya senge mvura, solvent, acid uye gasi rechisikigo.Inonyanya kushandiswa kucheka Kana kubatanidza svikiro mupombi, uye inogona kushandiswawo kugadzirisa mvura uye kutonga.

Kuenzaniswa nemamwe marudzi emavharuvhu, pneumatic bhora mavharuvhu ane angular sitiroko inobuda torque, kuvhura nekukurumidza, yakagadzikana uye yakavimbika, yakafara application, uye zvinotevera zvakanakira:

1. The thrust bearing inoderedza friction torque yehunde yevharuvhu, iyo inogona kuita kuti hunde yevharuvhu ishande zvakanaka uye nyore.

2. Anti-static basa: Chitubu chakagadzirirwa pakati pebhora, tsinde yevhavha uye muviri wevhavha, iyo inogona kutengesa kunze kwemagetsi emagetsi anogadzirwa panguva yekuchinja.

3. Pamusana pehutano hwakanaka hwekuzvidzivirira kwePTFE nezvimwe zvinhu, kurasikirwa kwekukwevera nebhora kuduku, saka hupenyu hwebasa hwepneumatic ball valve hurefu.

4. Diki rekudzivirira kwemvura: Pneumatic ball valve imwe yemhando duku dzekudzivirira kwemvura pakati pezvikamu zvose zvevhavha.Kunyangwe iyo yakaderedzwa-diameter pneumatic bhora vharafu, kupikisa kwayo kwemvura kudiki.

5. Kuvimbika kwevhavha stem seal: Sezvo tsvina yevhavha inongotenderera chete uye isingafambi kumusoro uye pasi, chisimbiso chekutakura chevhavha yevhavha haisi nyore kukuvadzwa, uye kukwanisa kuvhara kunowedzera nekuwedzera kwekumanikidzwa kwepakati.

6. Chigaro chevhavha chine basa rakanaka rekuvhara: mhete yekuvhara yakagadzirwa nezvinhu elastic zvakadai sePTFE zviri nyore kuvhara muhutano, uye kukwanisa kuvhara kwepneumatic ball valve kunowedzera nekuwedzera kwepakati.

7. Kupokana kwemvura kudiki, uye iyo yakazara-bore ball valve haina kana kuyerera kwekuyerera.

8. Chimiro chakareruka, diki diki uye uremu huremu.

9. Yakasimba uye yakavimbika.Iine nzvimbo mbiri dzekuisa chisimbiso, uye zvisimbiso pamusoro pezvinhu zvevhavha yebhora zvinoshandiswa zvakanyanya mumapurasitiki akasiyana-siyana, ane maitiro akanaka ekuisa chisimbiso uye anogona kuwana chisimbiso.Yakave zvakare yakashandiswa zvakanyanya muvacuum system.

10. Kushanda nyore nyore, kuzarura nokukurumidza nekuvhara, vheji yebhola inongoda kutenderera 90 ° kubva pakuzaruka zvakakwana kusvika kuvharwa, izvo zviri nyore kudzora kure-kure.

11. Zviri nyore kuchengetedza, valve yebhora ine chimiro chakareruka, mhete yekuisa chisimbiso inowanzo famba, uye zviri nyore kuparadzanisa uye kutsiva.

12. Kana yakazaruka zvakakwana kana kuti yakavharwa zvakakwana, nzvimbo dzekuvhara bhora uye chigaro chevhavha yakaparadzaniswa kubva pakati, uye kana iyo yepakati ichipfuura, haizokonzeri kukukurwa kwevhavha yekuvhara.

13. Yakasiyana-siyana yekushandiswa, madhayamita kubva kudiki kusvika kune akati wandei millimeters, yakakura kusvika kumamita akati wandei, uye inogona kuiswa kubva kune yakakwira vacuum kusvika kune yakanyanya kudzvanywa.

14. Nekuti vharafu yebhora ine midziyo yekupukuta panguva yekuvhura nekuvhara maitiro, inogona kushandiswa mukati mepakati neyakaturika yakasimba particles.

15. High processing precision uye mari yakakwirira.Hazvina kukodzera kushandiswa mukupisa kwepamusoro.Kana pane kusvibiswa mupombi, zviri nyore kuvharwa nekusvibiswa, zvichiita kuti valve haigone kuvhurwa.
