Gin ango ma pol kare ki tiyo kwede me umu valve?

Tye dul valve mapol, ento tic ne acel, ma en aye, me kubbe onyo juku pii ma mol i kin piny. Pi meno, peko me umu pa valve ni tye ma nen atir.

Me neno ni valve ni twero juku pii ma mol maber labongo pii mol, piire tek me neno ni valve ni tye maber. Tye tyen lok mapol pi pii ma mol ki i valve, medo ki kit ma ki yubu kwede ma pi opore, kabedo ma ki keto iye ma obale, jami ma ki keto iye ma obale, ma obale i kin kom valve ki bonnet, ki mukene. Peko eni weng twero kelo peko pa valve. Balo ku, man kelo peko me pii. Pi meno, diro me umu valve obedo diro ma pire tek ma mako tic pa valve ki rwom ne, ki mito kwedo ngec ma rwate ki matut.

Jami ma pol kare ki tiyo kwede me umu valve tye iye jami ma lubo ni:

1. NBR

Tek pa moo maber, tek me buru, tek ki lyeto maber, mako matek. Peko ne tye ni pe rwate ki lyeto ma piny, tek pa ozone ma pe ber, teko me mac ma pe ber, ki rwom me tic ma lapiny.

2. EPDM

Gin ma pire tek loyo i kom EPDM tye tek ne me gengo oxidation, gengo ozone ki gengo corrosion. Kit ma EPDM tye i dul pa polyolefin, en tye ki kit maber me vulcanization.

3. PTFE

PTFE tye ki teko me lweny i kom jami ma ki lwongo ni chemical, teko me lweny i kom moo ki jami ma ki lwongo ni solvents (labongo ketones ki esters), teko me gengo piny maber ki teko me gengo ozone, ento teko me gengo ngiico marac.

4. Gin ma ki yubu ki nyonyo

Ngec: Gin ma ki lwongo ni Cast iron ki tiyo kwede me yubu pii, yamo ki moo ki rwom me lyeto me≤100°C ki rwom me pek pa≤1.6mpa.

5. Nickel-based alloy

Ngec: Gin ma ki lwongo ni Nickel-based alloys ki tiyo kwede pi pipelines ma tye ki lyeto me -70~150°C ki teko me gedo PN≤20.5mpa.

6. Copper alloy

Copper alloy tye ki teko me juku tic maber ki ber pi pii ki yamo ma tye ki lyeto≤200℃ki rwom me PN≤1.6mpa.
