Okuba okutoorana omuringo gw‘okugaita ahagati y‘ekibunu ky‘ekinyonyi n‘omupiira nari eby‘okukoresa kihikire nari kitahikire nikiija kukwata butoosha aha kubaasa kw‘okugyendera, okutonnya, okutonnya n‘okusheeshasheesha kw‘ekibunu ky‘omupiira. Emiringo y‘okutaho valve erikukoresibwa munonga harimu: okutaho flange, okutaho wafer, okutaho butt welding, okutaho threaded, okutaho ferrule, okutaho clamp, okutaho self-sealing n‘ebindi bishushani by‘okutaho.
A. Okugaita kwa flange
Okuteerana kwa flange nivalvu y'ebihuguhugun’ebipande aha nshonda zombi z’omubiri gwa valve, ebirikuhikaana n’ebipande ebiri aha rubaju rw’omupiira, kandi nibiteebwa omu payipu barikubiteera obukomooko. Okuteerana kwa flange nigwo muringo gw’okuteerana ogurikukira kukozesebwa omu valvu. Flanges nizibaganisibwamu omu bicweka by’ahaiguru (RF), ebicweka by’ahaiguru (FF), ebicweka by’ahaiguru n’ebicweka by’ahaiguru (MF), n’ebindi.
B. Okugaita wafer
Valve neeteebwa ahagati y’ebipande bibiri, kandi omubiri gwa valve ogw’wafer ekihuguhugu valvuobwire obwingi aine ekiina ky’okutaho kubaasa kuhwera omu kutaho n’okutaho.
C. Okuteerana kwa solder
(1) Okuteerana kw’okuteerana kw’obutafaari: Enshonda zombi z’omubiri gwa valvu nizikorwaho omu nshonda z’okuteerana z’obutafaari kurugiirira aha byetengo by’okuteerana kw’obutafaari, ezirikuhikaana n’empiira z’okuteerana z’omupiira, kandi zihamibwa aha mupiira barikuteerana.
(2) Okuteerana kw’okuteerana kwa soketi: Enshonda zombi z’omubiri gwa valvu nizikorwa kurugiirira aha byetengo by’okuteerana kwa soketi, kandi nizikwatanisibwa n’omupiira gw’okuteerana omu soketi.
D. Okukwatiraine kw'orukoba
Okuteerana kw’orukoba n’omuringo gworobi gw’okuteerana kandi nigukira kukoresibwa aha bikwato bikye. Omubiri gwa valvu nigukorwa kurugiirira aha mutindo gwa buri ruhu, kandi hariho emiringo ebiri ey’orukoba rw’omunda n’orw’aheeru. Nikihikaana n’orukoba oruri aha payipu. Hariho emiringo ebiri y’okuteerana kw’enyuguta:
(1) Okukinga butoosha: Ehuuzi z’omunda n’ez’aheeru nizikora omurimo gw’okukinga butoosha. Okubaasa kureeba ngu okuteerana tikwasheesha, nikukira kwijura amajuta g’ekyoma, thread hemp na PTFE raw material tape; omuri ebyo PTFE raw material tape neekoresibwa munonga; ekintu eki kiine obushoboorozi burungi bw’okuzibira okusheenya kandi nikikora gye munonga omu kukinga. Kyanguhi kukoresa n’okubiika. Ku orikugisheenya, neebaasa kwihwaho kimwe ahabw’okuba n’ekishushani ekitarikukwaata, ekirikukira munonga amajuta g’ekyoma n’ebihimba by’orukoba.
(2) Okukinga okutarikuhikaana: amaani g’okukinga oruhu nigajanjaara aha kikwato ekiri ahagati y’enyonyi ibiri, kugira ngu ekikwato kikore omurimo gw’okukinga.
E. okutaaha omu nkora kwa ferrule
Enkwatanisa ya ferrule ekakorwa omu ihanga ryangye omu myaka egi yonka. Omusingye gwayo gw’okukwatira hamwe n’okukinga n’okugira ngu enjuma ku erikuba ehamire, ekirungo nikikwatwaho okugyemeserezibwa, n’ahabw’ekyo omukono gw’ekirungo niguruma omu kisiika ky’aheeru ky’omupiira, kandi aha mutwe gw’ekirungo ky’aheeru oguri nk’ekikoni nikikwatanisibwa n’ekicweka ekirikuteerana ahansi y’okugyemeserezibwa. Omunda y‘omubiri neekwatagana munonga n‘ekicweka ekiine akacupa, n‘ahabw‘ekyo okusheeshasheesha nikubaasa kuzibirwa omu muringo ogurikwesigwa. Nk’ebikwato ebirikukora nk’ebikwato. Ebirungi by’omuringo ogu gw’okugaita ni:
(1) Obuhango bukye, oburemeezi bukye, enkora eyorobi, okusheenya n’okuteerana kwanguhi;
(2) Amaani g’okuteerana ag’amaani, okukoresa kwingi, okuzibira okugyemeserezibwa kwingi (1000 kg/cm 2 ), obutagatsi bwingi (650 ° C) n’okushoberwa n’okutengeeta;
(3) Ebintu bitari bimwe na bimwe nibibaasa kutooranwa, ebihikire omu kurwanisa okusheenya;
(4) Ebyetaago by’okukora eby’okukoresa omu muringo oguhikire tibiri ahaiguru;
(5) Nikiba kiri kirungi kukita omu mwanya oguri ahaiguru munonga.
Obwahati, omuringo gw’okuteerana ferrule gukoresiibwe omu bintu ebimwe eby’okukoresa valve eziine oburaingwa bukye omu ihanga ryangye.
F. Okutaaha omu nkora
Ogu n’omuringo gw’okuteerana ogw’ahonaaho, nigwetenga obukomooko bubiri bwonka, kandi .valvu y'ekihuguhugu erimu omuherunikirungi ahari puresha nkyeza valvu z'ekihuguhuguebirikukira kusheenyuka. nk’ebikwato by’obuyonjo.
G. Okukwatanisa kw’omunda okw’okwehamya
Emiringo yoona ey‘okugaita eri aharuguru neekoresa amaani g‘aheeru kugaruzaho okugyemeserezibwa kw‘omugati kubaasa kutunga okukinga. Ebi ahaifo nibishoboorora aha muringo gw‘okwekwatanisa ogurikwehamya orikukoresa omuhimbo gwagati.
Empeta yaayo ey’okukinga neeteebwa aha rubaju rw’omunda kandi neekora enkokora emwe n’orubaju rurikureeba ahagati. Pressure y’omugati neejanjaara omu nkora y’omunda reero bwanyima eza omu mpeta y’okukinga. Aha rubaju rwa cone rw’enkokora emwe, amaani g’ebicweka bibiri nigakorwa, kimwe kiine Omurongooti gwa rwagati gw’omubiri gwa valve nigushushana n’aheeru, kandi ogundi nigunyigirizibwa aha kisiika ky’omunda eky’omubiri gwa valve. Amaani g’aha muheru n’amaani g’okwehamya. Oku pressure y’ahagati erikweyongyera, nikwo n’amaani g’okwehamya garikweyongyera. Nahabwekyo, omuringo ogu gw’okuteerana nigukora gye aha valvu z’amaani.
Wagyeragyeranisa n’okuteerana kwa flange, nikikiza ebintu bingi n’amaani g’abantu, kwonka kandi nikyetengyesa preload emwe, kugira ngu kibaasa kukoresibwa omu muringo ogurikwesigwa obu pressure eri omu valve etari ahaiguru. Valvu ezikozirwe barikukoresa omusingye gw’okwekingaho okutwarira hamwe ni valvu z’amaani maingi.
Hariho emiringo mingi y’okuteerana kwa valve, eky’okureeberaho, valve ezimwe ezikye ezitarikwetenga kwihwaho nizishemezibwa n’emipiira; ebimwe ebitari by’ekyoma nibikwatanisibwa n’ebikwato n’ebindi. Abarikukoresa Valve bashemerire kutwazibwa kurugirira aha mbeera emwe.
Ekihandiiko:
(1) Emiringo yoona ey’okugaita eine kugyendera aha mitwarize erikuhikaana n’okushoboorora emitindo kuzibira valvu etoorainwe kutaho.
(2) Obwire obwingi, omupiira gw’oburaingwa bwingi n’ekikopo nibikwatanisibwa n’ekipande, kandi omupiira gw’oburaingwa bukye n’ekikopo nibikwatanisibwa n’orukoba.
