Ni ibihe bikoresho bikunze gukoreshwa mu gufunga ama-valve?

Hari ubwoko bwinshi bwa valve, ariko imikorere y'ibanze ni imwe, ni ukuvuga guhuza cyangwa guca umurongo unyura hagati. Kubwibyo, ikibazo cyo gufunga valve kiragaragara cyane.

Kugira ngo valve ishobore gukata neza inzira ikoreshwa mu kuyihagarika idasesekaye, ni ngombwa kwemeza ko valve ifunze neza. Hari impamvu nyinshi zituma valve isohoka, harimo imiterere idasobanutse, ubuso budafite aho buhuriye n’imashini, ibice bifunga neza, guhuza neza hagati y’umubiri wa valve na bonnet, nibindi. Ibi bibazo byose bishobora gutuma valve ifunga nabi. Bityo, bigatera ikibazo cyo kuva amazi. Kubwibyo, ikoranabuhanga ryo gufunga valve ni ikoranabuhanga ry'ingenzi rijyanye n'imikorere n'ubwiza bwa valve, kandi risaba ubushakashatsi bwimbitse kandi bunoze.

Ibikoresho bikunze gukoreshwa mu gufunga ama-valve birimo ubwoko bukurikira:

1. Imbonerahamwe y'Ishusho (NBR)

Ubudahangarwa bwiza cyane n'amavuta, budahangarwa cyane, budahangarwa neza n'ubushyuhe, kandi bufatana neza. Ingaruka mbi zabyo ni ubushyuhe buke budahangarwa, budahangarwa nabi n'umwuka wa ozone, imiterere mibi y'amashanyarazi, ndetse no kudahinduka gato.

2. EPDM

Ikintu cy'ingenzi cyane cya EPDM ni ubudahangarwa bwayo buhanitse bwo kurwanya ogisijeni, ubudahangarwa bwa ozone no kudahangarwa kwa corruption. Kubera ko EPDM iri mu muryango wa polyolefin, ifite imiterere myiza ya vulcanization.

3. PTFE

PTFE ifite ubushobozi bukomeye bwo kurwanya ibinyabutabire, irwanya amavuta menshi n'ibintu biyungurura (usibye ketone na esters), irwanya ikirere neza kandi irwanya ozone, ariko irwanya ubukonje cyane.

4. Icyuma gishongeshejwe

Icyitonderwa: Icyuma gikoreshwa mu gukaraba amazi, gazi n'amavuta bifite ubushyuhe bwa≤100°C n'igitutu cyo hasi cya≤1.6mpa.

5. Aloyi ishingiye kuri nikeli

Icyitonderwa: Aloyi zishingiye kuri nikeli zikoreshwa ku miyoboro ifite ubushyuhe bwa -70~150°C na PN y'umuvuduko w'ubuhanga≤20.5mpa.

6. Ifu y'umuringa

Ifu y'umuringa ifite ubushobozi bwo kwangirika neza kandi ikwiriye imiyoboro y'amazi n'umwuka ifite ubushyuhe≤200℃n'umuvuduko wa PN≤1.6mpa.
