Omurimo gwa Valve Gasket & Endagiiriro y'okugikozesa

Valve gaskets zikozirwe kuzibira okusheeshasheesha okurikureetwaho okugyemeserezibwa, okusheenya, n‘okugaziha/okukyendeeza kw‘okwotsya ahagati y‘ebicweka. Obwire obu haihi boona bari flanged .okugaita's valvu nizetenga ebikwato by‘okuzikingira, okukoresa kwazo n‘obukuru bwazo nibitaana kurugiirira aha kika kya valvu n‘oku zitebeekanisiibwe. Omu kicweka eki,TWSniziija kushoboorora emyanya y‘okutaho valve n‘okutoorana eby‘okukoresa bya gasket.

I. Okukozesa okukuru kwa gaskets kuri aha flange joint y’okuteerana kwa valve.

Valvu erikukira kukozesebwa

1. Valvu y'omuryango
2. Valvu y'ensi
3. Valvu y'ekihuguhugu(na munonga valve y’ebinyonyi erimu ebiri ahagati n’ebiri ahagati)
4. Reeba valvu

Omuri valve ezi, gasket terikukoresibwa omu kuhabura okusheesheka nari okukingaho omunda ya valve ahabwayo, kureka neeteebwa ahagati y’ebipande bibiri (ahagati ya flange ya valve ahabwayo n’ekipande ky’omupiira). Omu kuhamya obukomooko, amaani g‘okukwatiraho garikumara nigakorwaho kuhangaho ekipande ekitarikuhinduka, ekirikuzibira okusheeshasheesha kw‘omugati aha nkoragana. Omurimo gwayo n’okwijuza obucweka obukye obutarikushushana ahagati y’ebicweka bibiri by’ekyoma ebiri aha rubaju rw’ekyoma, kuhamya ngu 100% byakingaho aha nkoragana.

II.Okukozesa Gasket omu Valve “Ekikingirizo kya Valve”

Valvu nyingi zitebeekanisiibwe n‘emibiri ya valvu etari emwe n‘emwe n‘ebikingirizo by‘okureeberera eby‘omunda ebyanguhi (nk‘okuhindura entebe za valvu, valvu za disiki, nari okusheenya ebisigarira), ebirikuheza bikateebwa hamwe. Gasket nayo neeyetengyesa aha nkoragana egi kureeba ngu yaaguma gye.

1. Okugaita ahagati y‘ekifundikizo kya valvu n‘omubiri gwa valvu gwa valvu y‘omuryango na valvu ya globe obwire obwingi nikyetengyesa okukoresa gasket nari O-ring.
2. Gasket eri omu mwanya ogu nayo neekora nk’ekikingirizo ekitarikuhinduka (static seal) okuzibira ebiri ahagati y’omubiri kuruga omu mubiri gwa valve kuza omu mwanya.

III. Gasket y'omutaano ahabw'ebika bya valvu

Valve ezimwe nizitaho gasket nk’ekicweka ky’ekibiina kyazo ky’okukinga ekikuru, ekitebeekanisiibwe kugaita omu nkora ya valve.

1. Valvu y'ekihuguhugu-ekikingirizo ky'entebe ya valvu

• Entebe ya butterfly valve buzima n’ekikwato ky’okukingira empeta, ekirikunyigirizibwa omu kisiika ky’omunda eky’omubiri gwa valvu nari ekirikuteebwa okwehinguririza disiki y’ekinyonyi.
• Obu ekihuguhugu .disikinikikinga, nikinyiga ekikwato ky’okukinga entebe ya valve kubaasa kuhangaho ekipande ky’amaani (nk’ekinyonyi .disikinizihinduka).
• Ebintu ebi nibikira kuba biri ebipiira (nk‘eky‘okureeberaho, EPDM, NBR, Viton) nari PTFE, ebikozirwe kubaasa kutwara eby‘amakuru n‘embeera z‘obutagatsi zitari zimwe na zimwe.

2. Omupiira Valvu-Ekikingirizo ky'entebe ya Valve

• Entebe ya valvu ya valvu y’omupiira nayo n’omuringo gw’ekikwato ky’okukinga, ekirikukira kukorwa omu bintu nka PTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), nari ebiveera ebigumire.
• Nikiha ekishumuruzo ahagati y‘omupiira n‘omubiri gwa valvu, nikikora byombi nk‘ekikingirizo ekitarikuhinduka (ekirikuhikaana n‘omubiri gwa valvu) n‘ekikingirizo ekiine amaani (ekirikuhikaana n‘omupiira ogurikwetoorora).

IV. Ni valve ki ezitarikukoresibwa munonga na gaskets?

1. Valves ezirikwemerera: Omubiri gwa valve nigushemezibwa butunu aha payipu, ekirikumaraho okwetenga kw’okutaho flanges na gaskets.
2. Valves eziine ebikwato by’okuteerana: Nizikira kukoresa ebikwato by’okukinga (nk’ekipande ky’ebintu ebitari bimwe na bimwe nari ekirikukinga), okutwarira hamwe nikimaraho okwetenga kw’okukinga.
3. Monolithic valves: Valvu ezimwe ez’omuhendo mukye nari valvu z’omutaano ziine omubiri gwa valvu ogutarikubaasa kusheenywa, n’ahabw’ekyo tiziine kikwato ky’okukingira valvu.
4. Valves eziine O-rings nari ebikwato ebizingirwe eby’ekyoma: Omu mirimo y’amaani, ey’obutagatsi bwingi, nari ey’omutaano, eby’okukingaho eby’omurembe nibibaasa kuza omu mwanya gw’ebikwato ebitari by’ekyoma ebya butoosha.

V. Omubugufu:

Valve gasket n’omuringo gw’ekintu ekirikukingaho ekishumuruzo ky’okusharaho omu bwijwire, nikikoresibwa munonga omu kugaita emipiira y’ebicweka by’omubiri ebitari bimwe na bimwe, kandi nikikoresibwa n’omu kukingaho ekifundikizo ky’ebicweka by’omubiri bingi. Omu kutoorana, nikyetengyesa kutoorana ekintu ky’okukinga ekihikire n’okukora kurugiirira aha kika kya valve, omuringo gw’okugikwatanisa, ahagati, obutagatsi n’okuteera.
