Nibihe bikoresho bisanzwe bifunga kashe ya valve?

Hariho ubwoko bwinshi bwa valve, ariko imikorere yibanze nimwe, ni ukuvuga guhuza cyangwa guca imigendekere yo hagati. Kubwibyo, ikibazo cyo gufunga valve kiragaragara cyane.

Kugirango umenye neza ko valve ishobora guca imigezi iringaniye neza nta kumeneka, ni ngombwa kwemeza ko kashe ya valve idahwitse. Hariho impamvu nyinshi zitera kumeneka, harimo igishushanyo mbonera cyubatswe kidafite ishingiro, guhuza ibimenyetso bifatika, guhuza ibice, gufunga neza, guhuza umubiri wa valve na bonnet, nibindi. Nibyiza, bityo ugatera ikibazo cyo kumeneka. Kubwibyo, tekinoroji yo gufunga ikorana buhanga nubuhanga bwingenzi bujyanye nimikorere ya valve nubuziranenge, kandi bisaba ubushakashatsi butunganijwe kandi bwimbitse.

Ibikoresho bisanzwe bifunga kashe ya valve harimo ubwoko bukurikira:

1. NBR

Kurwanya amavuta meza cyane, kwihanganira kwambara cyane, kurwanya ubushyuhe bwiza, gukomera cyane. Ingaruka zayo ni ubukonje buke buke, ubukana bwa ozone, imashanyarazi mibi, hamwe na elastique nkeya.

2. EPDM

Ikintu cyingenzi kiranga EPDM nuburyo bwiza bwo kurwanya okiside, kurwanya ozone no kurwanya ruswa. Kubera ko EPDM ari iyumuryango wa polyolefin, ifite ibintu byiza biranga ibirunga.

3. PTFE

PTFE ifite imiti ikomeye irwanya imiti, irwanya amavuta menshi hamwe nuwashonga (usibye ketone na esters), guhangana nikirere cyiza no kurwanya ozone, ariko birwanya ubukonje bukabije.

4. Shira icyuma

Icyitonderwa: Ibyuma bikozwe mumazi, gazi nibitangazamakuru bya peteroli hamwe nubushyuhe bwa≤100°C hamwe nigitutu cyizina cya≤1.6mpa.

5. Amavuta ya Nickel

Icyitonderwa: Amavuta ya Nickel akoreshwa mu miyoboro ifite ubushyuhe bwa -70 ~ 150°C hamwe nigitutu cyubwubatsi PN≤20.5mpa.

6. Umuringa

Umuringa wumuringa ufite imbaraga zo kwihanganira kwambara kandi ubereye amazi nu miyoboro hamwe nubushyuhe≤200℃n'umuvuduko w'izina PN≤1.6mpa.
