Piny ango ma pol kare jutiyo kudu pi juku valves?

Tye kit valve madwong, ento tic migi utiye acel, niwacu, ni mako nyo ni juku mol pa pii. Pieno, peko mi cego pa valve ubedo piny ma pire tek.

Mi neno nia valve copo juku pii ma mol maber manangu epe, umitu inen nia valve seal utiye maber. Tye the lembe madwong ma nyayu pii pa valve, ikinde utiye kit ma juyubu kudu ma ber ongo, kabedo ma juketho i iye ma rac, piny ma juketho i iye ma rwinyo, rwinyo pa valve man bonnet, man mange. Peko eni zo copo telu valve ma rwinyo ngo. Ber, eno kelo peko mi pii. Pieno, diro mi juku valve ubedo diro ma pire tek ma mako tic pa valve man ber pa valve, man mitu timo sayusac ma iyere man ma thuc.

Jam tic ma pol kare jutiyo kudu pi juku valve uketho i iye kit ma e:

1. NBR

Kite maber mi juku moo, tego pa jamb tiyo maber, tego pa lyethu maber, mako matek. Peko pare utiye rwom ma piny pa lyethu, rwom ma piny pa ozone, rwom pa mac ma ber ungo, man rwom ma piny pa elasticity.

2. EPDM

Piny ma pire tek uloyu pa EPDM utiye tek pa oxidation, ozone man corrosion. Calu EPDM utiye ikind polyolefin, etiye ku kit maber mi vulcanization.

3. PTFE

PTFE utiye ku tego pa kemikol, tego pa moo man solvents (muweko ketones ku esters), tego pa koth man tego pa ozone, ento tego pa ngico marac.

4. Cast iron

Poi: Cast iron jutiyu kudu pi pii, yamu man moo ku lyethu pa≤100°C man pressure ma nok pa≤1.6mpa.

5. Nickel-based alloy

Poi: Nickel-based alloys jutiyu kudu pi pipelines ku lyethu pa -70~150°C man PN mi tic mi gedo≤20.5mpa.

6. Copper alloy

Copper alloy utiye ku kero maber mi juku nyoth man eber pi pii man paip mi lyethu ku lyethu≤200°Cman nominal pressure PN≤1.6mpa.
