Okukinga valve n'ekicweka kikuru kya valve yoona, ekigyendererwa kyayo ekikuru n'okuzibira okusheeshasheesha,valvuentebe y‘okukinga nayo neeyetwa empeta y‘okukinga, n‘ekitongore ekirikukwatagana butunu n‘ekintu ekiri omu payipu kandi kikaremesa ekintu kusheesheka. Valve ku erikuba neekoresibwa, nihaba hariho ebintu bitari bimwe na bimwe omu payipu, nk’amaizi, gaasi, amajuta, ebintu ebirikusheenya, n’ebindi, kandi ebikwato by’okukinga valvu zitari zimwe na zimwe nibikoresibwa omu myanya etari emwe n’emwe kandi nibibaasa kumanyiira ebintu bitari bimwe na bimwe.
TWSValvenikikwijutsya ngu ebintu by’okukinga valve nibibaasa kubaganisibwamu emiringo ebiri, nikwo kugira ngu eby’ekyoma n’ebitari by’ekyoma. Ebikwato ebitari by’ekyoma nibikira kukoresibwa omu mipiira aha bwire bw’obutagatsi n’oburemeezi obuhikire, kandi ebikwato by’ekyoma biine emirimo mingi kandi nibibaasa kukoresibwa aha bwire bw’obutagatsi bwingi. okugyemeserezibwa kwingi.
Orubaara orukozirwe abantu nirukira orubaju rw’obuhangwa omu kugumira amajuta, okugumira obutagatsi n’okugumira okusheenya. Okutwarira hamwe, ebiriisa by’okukora eby’emipiira y’obuhangwa ni t .≤150°C, orubaare rw’obuhangwa ni t .≤60°C, kandi orupiira nirukoresibwa omu kukingaho ebikwato bya globe, ebikwato by’omuryango, ebikwato by’okutaho diaphragm, ebikwato by’ebinyonyi, ebikwato by’okukyebera, ebikwato by’okunyiganyiga n’ebikwato ebindi ebiine pressure y’eiziina PN .≤1MPa.
2. Nayiloni
Nylon eine obumanyiso bw’okuteerana okukye n’okuzibira gye okusheenya. Nylon neekira kukozesebwa omu bipimo by’omupiira n’ebipimo by’ensi ebiine obutagatsi t .≤90°C na puresha y’eiziina PN .≤32MPa.
3. Eby'okurya ebirimu ebiriisa
PTFE neekira kukozesebwa omu bikwato bya globe, ebikwato by’omuryango, ebikwato by’omupiira, n’ebindi ebiine obutagatsi t .≤232°C na pressure y’eiziina PN .≤6.4 MPa.
4. Ekyoma ekicukire
Ekyoma ekirikucumitwa nikikoresibwa omu bikwato by’okuteeraho omuryango, ebikwato by’okuteeraho ensi, ebikwato by’okuteeraho, n’ebindi ahabw’obutagatsi t≤100°C, okugyemeserezibwa kw’eiziina PN≤1.6MPa, gaasi n’amajuta.
5. Ekirungo kya Babbitt
Babbitt alloy neekoresibwa omu nkora ya ammonia globe valvu n’obutagatsi t-70 ~ 150 .°Cn’okugyemeserezibwa kw’eiziina PN .≤2.5MPa.
6. Omuringa gw'omuringa
Ebintu ebirikukira kukozesebwa omu kuhanga emiringa n’ekikomo ky’etini 6-6-3 n’ekikomo kya manganese 58-2-2. Copper alloy eine obutabaasa kujwara gye kandi neekora gye omu maizi n’omuyaga n’obutagatsi t .≤200°Cn’okugyemeserezibwa kw’eiziina PN .≤1.6MPa. Nikikira kukozesebwa omu bikwato by’omuryango, ebikwato by’ensi, ebikwato by’okukyebera, ebikwato by’okutaho, n’ebindi.
7. Chrome ekyoma ekitarikukyereba
Emiringo y’ekyoma ekirikukoresibwa munonga ekya chromium stainless steel ni 2Cr13 na 3Cr13, ezizimiire kandi ziine obutagatsi, kandi ziine obushoboorozi burungi bw’okuzibira okusheenya. Nikikira kukozesebwa aha valvu z’amaizi, omuyaga n’amajuta g’ebishaka n’obutagatsi t .≤450°Cn’okugyemeserezibwa kw’eiziina PN .≤32MPa.
8. Ekyoma ekitarikukyereba
Omuringo gw’ekyoma ekirikukoresibwa munonga ekya chromium-nickel-titanium ni 1Cr18Ni9ti, ekiine obushoboorozi burungi bw’okuzibira okusheenya, okuzibira okusheenya n’okuzibira obutagatsi. Nikirungi aha steam n’ebindi bihandiiko ebiine obutagatsi t .≤600°C na pressure y’eiziina PN .≤6.4MPa, kandi neekoresibwa omu bikwato bya globe, ebikwato by’omupiira, n’ebindi.
9. Ekyoma ekirikukora nitride
Omuringo gw’ekyoma ekirikukoresibwa munonga ni 38CrMoAlA, ekiine obutafaari burungi bw’okuzibira okusheenya n’okuzibira okushara bwanyima y’okukikozesa carburizing. Nikikira kukozesebwa omu bipimo by’omuryango gw’amashanyarazi ebiine obutagatsi t .≤540°Cn’okugyemeserezibwa kw’eiziina PN .≤10MPa.
10. Okukoresa boroni
Boronizing neekora butoosha aha rubaju rw’okukingaho kuruga omu kintu ky’omubiri gwa valve nari omubiri gwa disc, reero bwanyima ekore okujanjaba aha rubaju rwa boronizing. Eitaka eririkukingaho riine obutafaari burungi bw’okuzibira okujwara. Ahabw’okufuka valvu y’amashanyarazi.
Valve ku erikuba neekoresibwa, enshonga ezi oine kutaho omutima ni ezi:
1. Okukora kwa valve okukingaho kushemerire kugyezibwa kureeba ngu yakora gye.
2. Reeba yaaba ekicweka ky’okukingaho valvu kijwaire, kandi okiboneze nari okihindure kurugiirira aha mbeera.
