Chiwonetsero cha Valave ndi gawo lofunikira la ma Valve. Kodi zida zosindikizira zidali ziti? Tikudziwa kuti valavu yokamba za mphete za mphete zimagawidwa m'magulu awiri: zitsulo komanso zopanda chitsulo. Izi ndizoyambira mwachidule kugwiritsidwa ntchito kwa zinthu zingapo zosindikizira, komanso mitundu wamba yogwiritsidwa ntchito.
1. Kupanga mphira
Katundu wopangidwa kwathunthu monga kukana mafuta, kukana kutentha ndi kukana kutukuka ndikwabwino kuposa za mphira wachilengedwe. Nthawi zambiri, kugwiritsa ntchito kutentha kwa mphira ndi T≤150 ℃, ndipo kutentha kwa mphira wachilengedwe ndi T≤60 ℃. Rubber amagwiritsidwa ntchito kusindikizidwa ma valves padzikoli,mphira, Mavavu a Diaphragm,rubber wokhala nawo valavu, rubber wokhala ndi Swing FAVV (Chongani Mavalve), kutsina ma valve ndi ma valve ena okhala ndi bondol pnp1mpa.
2. Naylon
Nylon ali ndi mawonekedwe a chiwonetsero chaching'ono komanso kukana bwino. Nylon amagwiritsidwa ntchito kwambiri pa ma valve a mpira ndi mavesi a Glober ndi kutentha T≤90 ℃ ndi mwanminal kupsinjika PNP32MPA.
3. Ptfe
PTFF amagwiritsidwa ntchito kwambiri kwa ma valves a Globe,Mavesi pachipata, ma valve a mpira, ndi zina mwawiri ndi kutentha kwa T≤232 ℃ ndi mwadzina mwadzina.
4. Ikani chitsulo
Chitsulo chimagwiritsidwa ntchitopachipata, Globvu R Valve, plug Valve, etc. ya kutentha T≤100 ℃, mwanral testation pn≤1.6mna, mpweya ndi mafuta.
5. BOBBITT SHOY
BOBBITT SHOLOY imagwiritsidwa ntchito ngati ma ammonia glober ndi kutentha T-70 ~ 150 ~ ℃ ndi mwadzina.
6. Copper Cloy
Zofala Zofala Copper zili ndi 6-6-3 tini titani ndi 58-2-2 mkungudza wa Manganese. Copperper Smoy imavala bwino ndipo ndi yoyenera madzi ndi nthunzi ndi kutentha T≤200 ℃ ndi mwanminal pnp1.6mpu. Nthawi zambiri imagwiritsidwa ntchito mkatiMavesi pachipata, ma valves padzikoli,Chongani Mavalve, Valogi ya Sulani, ndi zina.
7. Chitsulo chosapanga dzimbiri
Magawo omwe amagwiritsidwa ntchito kwambiri a chromium osapanga dzimbiri ndi 2cr13 ndi 3cr13, omwe adazimitsidwa komanso kupsinjika, ndikutsutsa zabwino. Nthawi zambiri imagwiritsidwa ntchito m'matatoni monga madzi, nthunzi ndi petroleum ndi kutentha T≤450 ℃ ndi mwanminal kuprost Pnp32MPA.
8. Chromium-nickel-titanium dambo wopanda dzimbiri
Kalasi yogwiritsidwa ntchito kawirikawiri ya chromium-nickel-titaniyam dzingu osapanga dzimbiri ndi 1cr18Nni9Ti, zomwe zimatsutsana ndi kutukwana komanso kukana kutentha. Ndioyenera Steam, Nitric Acid ndi Acinjidwe Ena ndi Kutentha kwa T≤600 ℃ ndi mwanminal v
9. Chitsulo cha nitele
Kalasi yogwiritsidwa ntchito kawirikawiri ya chitsulo cha nitrid ndi 38crmoala, omwe ali ndi vuto labwino komanso kukana zikanda pambuyo pakuchiritsa. Nthawi zambiri zimagwiritsidwa ntchito pachipata champhamvu kwambiri ndi kutentha kwa T≤540 ℃ ndi mwadzina.
10. Kusuntha
Kutulutsa mwachindunji kumathandizanso kutsitsa komwe kuli thupi la valavu kapena thupi la disc, kenako ndikuchotsa chithandizo chamankhwala, malo otsekemera ali ndi vuto kukana. Chogwiritsidwa ntchito mu valve.
