Igipapuro nigice gifunga kashe gikemura "kwiruka, gusohora, gutonyanga, no kumeneka".Kubera ko hariho ibyapa byinshi bifunga kashe, ukurikije ubwo buryo bwo gufunga kashe, gasketi iringaniye, gasketi ya elliptique, lisansi ya lisansi, gaseke ya cone, gasketi y'amazi, O-impeta, hamwe na gasketi zitandukanye zo kwifungisha byagaragaye.Kwishyiriraho neza gasketi bigomba gukorwa mugihe imiterere ya flange ihuza cyangwa imiterere ihuza urudodo, hejuru yikimenyetso cya static hamwe na gasketi ntagushidikanya, nibindi bice bya valve ntibiba byiza.
1. Mbere yo gushiraho igipapuro, shyiramo igifu cya grafite cyangwa ifu ya grafite ivanze namavuta (cyangwa amazi) hejuru yikimenyetso, gasike, urudodo na bolt nibice bizunguruka.Igipapuro na grafite bigomba guhorana isuku.
2. Igipapuro kigomba gushyirwaho hejuru yikidodo kugirango gishyirwe hagati, gikosore, ntigishobora guhindagurika, ntigere mu cyuho cya valve cyangwa kuruhukira ku rutugu.Diameter y'imbere ya gaze igomba kuba nini kuruta umwobo w'imbere wubuso bwa kashe, naho diameter yo hanze igomba kuba ntoya ugereranije na diametre yinyuma yubuso bwa kashe, kugirango tumenye neza ko igitereko gifatanye neza.
3. Igice kimwe gusa cya gaze yemerewe gushiraho, kandi ntibyemewe gushiraho ibice bibiri cyangwa byinshi hagati yikimenyetso kugirango bikureho ikinyuranyo hagati yububiko bubiri.
4. Igikuta cya oval kigomba gufungwa kugirango impeta zimbere ninyuma za gasike zihure, kandi impande zombi za gasike ntizigomba guhura nu munsi wigitereko.
5. Kugirango ushyireho O-impeta, usibye ko impeta na groove bigomba kuba byujuje ibisabwa, ingano yo kwikuramo igomba kuba ikwiye.Uburinganire bwicyuma O-impeta ni 10% kugeza 40%.Igipimo cyo guhindagurika kwa reberi O-impeta ni silindrike.Ikimenyetso gifatika ku gice cyo hejuru ni 13% -20%;Uburinganire bwa static ni 15% -25%.Kumuvuduko mwinshi wimbere, compression deformation igomba kuba hejuru mugihe ukoresheje vacuum.Hashingiwe ku kwemeza kashe, ntoya yo kugabanuka kwa compression, nibyiza, bishobora kwagura ubuzima bwa O-impeta.
6. Umuyoboro ugomba kuba ufunguye mbere yuko gasketi ishyirwa ku gifuniko, kugirango bitagira ingaruka ku iyinjizwa no kwangiza valve.Mugihe ufunze igifuniko, uhuze umwanya, kandi ntukavugane nigitutu usunika cyangwa ukurura kugirango wirinde kwimuka no gushushanya.Mugihe uhinduye umwanya wigifuniko, ugomba kuzamura igifuniko gahoro, hanyuma ukagihuza witonze.
7. Kwishyiriraho ibipapuro byahinduwe cyangwa bifatanye bigomba kuba nkibiseke biri mumwanya utambitse (igipfundikizo cyigitereko cyo guhuza imigozi ntigomba gukoresha imiyoboro ya pipe niba hari ikibanza).Kwizirika kuri screw bigomba gufata uburyo bwo guhuza, guhinduranya, ndetse nuburyo bwo gukora, kandi ibimera bigomba guhuzwa neza, neza kandi ntibirekure.
8. Mbere yuko gasike ihagarikwa, igitutu, ubushyuhe, imiterere yikigereranyo, hamwe nibintu bya gasike bigomba kumvikana neza kugirango hamenyekane imbaraga zabanje gukomera.Imbaraga zo kubanziriza gukomera zigomba kugabanuka uko bishoboka kwose kugirango igeragezwa ryumuvuduko ridatemba (imbaraga zirenze-kwizirika byoroshye kwangiza gasike kandi bigatuma gasike itakaza imbaraga).
9. Igikuta kimaze gukomera, kigomba kwemezwa ko hari icyuho kibanziriza gukomera kubice bihuza, kugirango habeho umwanya wo kubanza gukomera mugihe igitereko kiva.
10. Iyo ukora ku bushyuhe bwinshi, bolts izagira ubushyuhe bwinshi, kuruhuka, no kwiyongera kwa deformasiyo, biganisha kumyuka kandi bisaba gukomera.Ibinyuranye, mugihe cy'ubushyuhe buke, ibimera bizagabanuka kandi bikenera gukonja.Gushyushya bishyushye ni igitutu, kurekura ubukonje ni ukugabanya umuvuduko, gukomera no gukonjesha bigomba gukorwa nyuma yo gukomeza ubushyuhe bwakazi kumasaha 24.
11. Iyo isukari isukuye ikoreshwa hejuru yikimenyetso, ubuso bugomba gusukurwa cyangwa kuvurwa hejuru.Ubuso bwa kashe buringaniye bugomba kuba buhoraho nyuma yo gusya, kandi ibifatika bigomba gukoreshwa neza (ibifatika bigomba kuba bihuye nibikorwa byakazi), kandi umwuka ugomba gukumirwa uko bishoboka kose.Igice gifatika ni 0.1 ~ 0.2mm.Urudodo rwa screw ni kimwe nuburinganire bwa kashe.Ibice byombi byitumanaho bigomba gutwikirwa.Iyo winjiye, igomba kuba ihagaritse kugirango byorohereze umwuka.Kole ntigomba kuba nyinshi kugirango wirinde kumeneka no kwanduza izindi valve.
12. Iyo ukoresheje kaseti ya firime ya PTFE kugirango ushireho urudodo, aho intangiriro ya firime igomba kuramburwa yoroheje kandi ikomekwa kumutwe;noneho kaseti irenze aho itangirira igomba gukurwaho kugirango firime ifatanye kumutwe muburyo bwa wedge.Ukurikije icyuho cyurudodo, muri rusange gikomeretsa inshuro 1 kugeza kuri 3.Icyerekezo kizunguruka kigomba gukurikira icyerekezo, kandi impera yanyuma igomba guhurirana nintangiriro;buhoro buhoro gukurura firime muburyo bwa wedge, kugirango ubunini bwa firime bukomere neza.Mbere yo gushiramo, kanda firime kumutwe wurudodo kugirango firime ibashe guhurizwa mumutwe wimbere hamwe na screw;guswera bigomba gutinda kandi imbaraga zigomba kuba ndetse;ntukongere kwimuka nyuma yo gukomera, kandi wirinde guhinduka, bitabaye ibyo bizoroha kumeneka.
