Valve ya kuzimya ya pneumatic
Ibindi bicuruzwa
I. Intangiriro:
J641H valve ifungurira ya pneumatic ikoreshwa mu mizabibu y’ibintu byoroshye mu nganda z’imashini, ubuvuzi, ibikoresho by’umucanga, inganda za elektrika n’ibindi byo, mu gihe cy’uburebure bw’umuvuduko PN1.6~16.0MPa, ubushyuhe bw’akazi bwa -29 kugeza 550 ℃, kugirango uhindure cyangwa uhindure ibintu byo. Ibintu byo bikoreshwa ni: amazi, amavuta, umwotsi, ibintu by’umutobe n’ibindi. Uburyo bwo gukora ni: gukora ku ntoki, gukora kwa gear, gukora kwa elektrika, gukora kwa pneumatic n’ibindi. Ibintu bikoreshwa mu cylinder: umwotsi ukomeye, nitrogen. Imikorere iroroshye, ubwubatsi no kuyirengera biroroshye; umuvuduko wo gukora muto, igihe cyo gufungura no gufunga muto; umubiri wo gufunga (valve disc) na valve seat seal face bikoresha cone seal, ingufu yo gufunga muto, irashobora kwirinda imyanda, seal irashobora kwizerwa. Iyi valve ikoresha cylinder ya double acting, ikoresha umwotsi uva mu gikoni cyo hejuru cyangwa cyo hasi kugirango ikoreshe valve mu kure, gukora biroroshye kandi biroroshye. Ibintu bikoreshwa mu cylinder: umwotsi ukomeye, nitrogen. Imikorere iroroshye, ubwubatsi no kuyirengera biroroshye; umuvuduko wo gukora muto, igihe cyo gufungura no gufunga muto; umubiri wo gufunga (valve disc) na valve seat seal face bikoresha cone seal, ingufu yo gufunga muto, irashobora kwirinda imyanda, seal irashobora kwizerwa. Valve seat irashobora kuba valve seat ishobora guhindurwa, irashobora guhuza ibintu byo bikoreshwa na seal face byo kugirango ihurize n’ibyo bikenewe mu kazi, ikongera igihe cyo kugira.
II. Ibyo Bya Product:
1. Product ikorwa ku isano ya standard GB12235, ubwubatsi bwiza, seal irashobora kwizerwa, imikorere iroroshye, ishusho nziza.
2. Seal face ya valve disc na valve seat bikoresha stellite cobalt base hard alloy overlay welding, irashobora kwirinda imyanda.
3. Valve rod yakoze ku moderi ya quenching na tempering hamwe na surface nitriding treatment, ifite imikorere myiza yo kurwanya corrosion no kurwanya abrasion.
4. Irashobora gukoresha ibintu byo bikoreshwa mu flange standard zose na flange seal face, ihurize n’ibyo bikenewe mu nganda n’ibyo bikenewe n’abakoresha.
III. Standard yo Kora Product:
Gukora no gukora: GB12235
Uburebure bw’ubwubatsi: GB12221
Pressure temperature grade: GB9131 JB/T74 HG20604
IV. Ibyo Product Ikora:
Iyi valve ikoresha cylinder ya double acting, ikoresha umwotsi uva mu gikoni cyo hejuru cyangwa cyo hasi kugirango ikoreshe valve mu kure, gukora biroroshye kandi biroroshye. Ibintu bikoreshwa mu cylinder: umwotsi ukomeye, nitrogen. Imikorere iroroshye, ubwubatsi no kuyirengera biroroshye; umuvuduko wo gukora muto, igihe cyo gufungura no gufunga muto; umubiri wo gufunga (valve disc) na valve seat seal face bikoresha cone seal, ingufu yo gufunga muto, irashobora kwirinda imyanda, seal irashobora kwizerwa. Valve seat irashobora kuba valve seat ishobora guhindurwa, irashobora guhuza ibintu byo bikoreshwa na seal face byo kugirango ihurize n’ibyo bikenewe mu kazi, ikongera igihe cyo kugira.
