Ni ibihe bikoresho bikoreshwa cane mu gukingira amavalve?

Hari ubwoko bwinshi bw’amavalve, ariko igikorwa nyamukuru ni kimwe, ni ukuvuga gufatanya canke guca umuvuduko uri hagati. Ni co gituma ingorane yo gukingira iyo valve iragaragara cane.

Kugira ngo iyo valve ishobore guca neza umuvuduko wo hagati ata n’umwe asohoka, birakenewe ko ikidodo c’iyo valve kiguma kidasenyutse. Hari impamvu nyinshi zituma valve ivuza, harimwo n’imiterere idasanzwe, ubumuga bwo gukingira, ibihimba vy’ugufatanya bitari vyiza, ukuntu umubiri w’ivalve n’igipfukisho c’ivalve bidakora neza, n’ibindi. Ego cane, gutyo bikaba bituma habaho ingorane y’ugusohoka. Rero, ubuhinga bwo gukingira amavalve ni ubuhinga buhambaye bujanye n’ubushobozi n’uburyo bw’amavalve, kandi busaba ubushakashatsi butunganye kandi bwimbitse.

Ivyo bikoresho bikoreshwa cane mu gukingira amavalve ahanini birimwo ubwoko bukurikira:

1. NBR

Amavuta meza cane, guhangana n’ukwambara kwinshi, guhangana n’ubushuhe bwiza, ukwifatanya gukomeye. Inyungu zayo ni uko idashobora guhangana n’ubushuhe buke, idashobora guhangana n’umuyaga w’ikirere (ozone), idashobora gukoresha neza amashanyarazi, kandi idashobora gukomera gatoyi.

2. EPDM

Ikintu gihambaye cane kiranga EPDM ni ubushobozi bwayo bwo guhangana n’ivyuma bitera umuriro, ubushobozi bwo guhangana n’ivyuma bitera umuriro (ozone) n’ubushobozi bwo guhangana n’ivyuma bitera umuriro (corrosion). Kubera ko EPDM iri mu muryango wa polyolefine, irafise ubushobozi bwiza cane bwo gutera ivyatsi.

3. PTFE

PTFE irafise ubushobozi bukomeye bwo guhangana n’imiti, ishobora guhangana n’amavuta menshi n’ibinyabuzima (kiretse ketones na esters), ishobora guhangana n’ibihe vyiza n’umuyaga w’ikirere (ozone), ariko ishobora guhangana n’ubukonje buke.

4. Icuma gicuzwe

Iciyumviro: Ivyuma bikoreshwa mu mazi, gazi n’amavuta bifise ubushuhe bwa 100.000.≤100°C n’umuvuduko w’izina w’≤1,6mpa.

5. Igikoresho gishingiye kuri nickel

Iciyumviro: Ivyuma bishingiye kuri nickel bikoreshwa ku mirongo y’amazi ifise ubushuhe bwa -70~150.°C n'umuvuduko w'ubuhinga PN≤20,5mpa.

6. Umuringa

Igikoresho c'umuringa gifise ubushobozi bwo guhangana n'ugusambuka kandi kirabereye imiyoboro y'amazi n'umwotsi ifise ubushuhe .≤200°Cn'umuvuduko w'izina PN≤1,6mpa.
