Umgomo wokukhetha i-globe valve
I-valve yokuvala ibhekisela ku-valve enengxenye yayo yokuvala (idiski) ehamba emgqeni ophakathi wesihlalo se-valve. Ngokusho kwalolu hlobo lokunyakaza kwe-valve disc, ushintsho lwe-port yesihlalo se-valve luhambisana nokushaya kwe-valve disc. Njengoba i-stroke yokuvula noma yokuvala yesiqu se-valve salolu hlobo lwe-valve imfushane kakhulu, futhi inomsebenzi wokusika othembekile kakhulu, futhi ngenxa yokuthi ushintsho lwe-port yesihlalo se-valve luhambisana ngqo nokushaya kwe-valve disc, lufanele kakhulu ukulungiswa kokugeleza. Ngakho-ke, lolu hlobo lwe-valve lufanele kakhulu ukusetshenziswa njenge-shut-off noma ukulungiswa kanye ne-throttling.

Umgomo wokukhetha i-globe valve uthi:
1. I-valve yokumisa kufanele isetshenziswe epayipini noma kudivayisi yokushisa okuphezulu kanye ne-medium enomfutho ophezulu. Njengezitshalo zamandla ezishisayo, izitshalo zamandla enuzi, amapayipi okushisa okuphezulu kanye nomfutho ophezulu wezinhlelo ze-petrochemical.
2. Emapayipini angadingi ukumelana okuqinile kwe-convection. Okusho ukuthi, lapho ukulahlekelwa kwengcindezi kungacatshangwa khona.
3. Kuma-valve amancane, ama-valve enaliti, ama-valve ezinsimbi, ama-valve okuthatha isampula, ama-valve okulinganisa ukucindezela, njll. angasetshenziswa.
4. Kukhona ukulungiswa kokugeleza noma ukulungiswa kwengcindezi, kodwa ukunemba kokulungiswa akuphezulu, futhi ububanzi bepayipi buncane kakhulu, njengepayipi elinendawo yokudlula engu-≤50mm, kufanele likhethwe.
5. Umanyolo omncane kanye nomanyolo omkhulu ekukhiqizweni kwezimboni zokwenziwa kufanele basebenzise ama-globe valve ane-angle yokucindezela okuphezulu noma ama-globe valve ane-angle yokucindezela okuphezulu kwe-PN160 kanye nomfutho ojwayelekile we-16MPa noma i-PN320 kanye nomfutho ojwayelekile we-32MPa.
6. Emsebenzini wokususa i-siliconization wenqubo ye-alumina Bayer kanye namapayipi avame ukuphekwa, kulula ukukhetha i-valve yokumisa ukugeleza okuqondile noma i-valve yokumisa ukugeleza okuqondile enomzimba we-valve ohlukanisiwe, isihlalo se-valve singasuswa, kanye nepheya lokuvala i-carbide eliqinisiwe.
7. Kumaphrojekthi okuphakelwa kwamanzi nokushisa ekwakhiweni kwedolobha, amapayipi amancane adluliswa ngokwegama, futhi ama-valve okumisa, ama-valve okulinganisela noma ama-valve e-plunger angakhethwa, njengepayipi elidluliswa ngokwegama elingaphansi kuka-150mm.
INortech ingenye yabakhiqizi bama-valve ezimboni abahamba phambili eShayina abanesitifiketi sekhwalithi se-ISO9001.
Imikhiqizo emikhulu:I-Butterfly Valve,I-Ball Valve,I-Valve yeSango,Hlola i-Valve,I-Globe Vavlve,Izihlungi ze-Y,I-Acurator kagesi,Ama-Acurators omoya.
