Umgomo wokukhetha we-globe valve
I-valve yokuvala ibhekisela kuvalvu ingxenye yayo yokuvala (idiski) ehamba emgqeni omaphakathi wesihlalo sevalvu.Ngokwaleli fomu lokunyakaza kwediski ye-valve, ukuguqulwa kwembobo yesihlalo se-valve ngokulingana ne-valve disc stroke.Njengoba i-stroke yokuvula noma yokuvala yesiqu se-valve yalolu hlobo lwe-valve imfushane, futhi inomsebenzi othembeke kakhulu wokunqamula, futhi ngenxa yokuthi ukuguqulwa kwembobo yesihlalo se-valve kuhambisana ngokuqondile nokushaywa kwe-valve disc. , ifaneleka kakhulu ukulungiswa kokugeleza.Ngakho-ke, lolu hlobo lwe-valve lufaneleka kakhulu ukusetshenziswa njengendlela yokuvala noma ukulungiswa nokudonsa.

Isimiso sokukhetha i-valve yomhlaba yile:
1. I-valve yokumisa kufanele isetshenziswe epayipini noma kudivayisi yokushisa okuphezulu kanye ne-high pressure medium.Njengezimboni zamandla ashisayo, izitshalo zamandla enuzi, izinga lokushisa eliphezulu kanye namapayipi anengcindezi ephezulu yezinhlelo ze-petrochemical.
2. Emapayipini angadingi ukuphikiswa okuqinile kwe-convection.Okungukuthi, lapho ukulahlekelwa kwengcindezi kungacatshangwa.
3. Ngama-valve amancane, ama-valve enaliti, ama-valve ensimbi, ama-sampling valves, ama-valve gauge gauge, njll angasetshenziswa.
4. Kukhona ukulungiswa kokugeleza noma ukulungiswa kwengcindezi, kodwa ukunemba kokulungiswa akuphakeme, futhi ububanzi bepayipi buncane kakhulu, njengepayipi ene-passage yokulinganisa engu-≤50mm, kufanele ikhethwe.
5. Umanyolo omncane kanye nomanyolo omkhulu ekukhiqizeni izimboni zokwenziwa kufanele kusetshenziswe ama-valve e-globe angle yokucindezela okuphezulu noma ama-valve e-globe angle yokucindezela okuphezulu nokucindezela okuzisholo kwe-PN160 kanye nokucindezela okuzisholo kwe-16MPa noma i-PN320 kanye nokucindezela okulinganiselwe okungu-32MPa.
6. Ku-workshop ye-desiliconization yenqubo ye-alumina Bayer kanye namapayipi athambekele ekuphekeni, kulula ukukhetha i-valve yokumisa ukugeleza okuqondile noma i-valve yokumisa ukugeleza okuqondile ngomzimba we-valve ohlukanisiwe, isihlalo se-valve singasuswa, kanye nepheya elifakwe usimende le-carbide sealing.
7. Emisebenzini yokuphakela amanzi kanye nokushisisa ezakhiweni zasemadolobheni, amapayipi amancane adlula, futhi amavalvu okumisa, amavalvu ebhalansi noma ama-plunger valve angakhethwa, njengamapayipi adlula ngaphansi kuka-150mm.
I-Nortech ingomunye wabakhiqizi abahamba phambili bamavalvu ezimbonini e-China abanesitifiketi sekhwalithi ye-ISO9001.
Imikhiqizo emikhulu:I-Butterfly Valve,I-Ball Valve,Ivalve yesango,Hlola Valve,I-Globe Vavlve,I-Y-Strainers,I-Acurator kagesi,Ama-Acurator Womoya.
