1. Ongeraho amavuta yo gufunga

Kuri valve idakoresha amavuta yo gufunga, tekereza kongeramo amavuta yo gufunga kugirango utezimbere imikorere yikimenyetso.

2. Ongeraho uwuzuza

Kugirango tunoze imikorere yikimenyetso cyo gupakira kumurongo wa valve, uburyo bwo kongeramo paki burashobora gukoreshwa. Mubisanzwe, ibyiciro bibiri cyangwa byinshi-bivanze byuzuye byuzuzwa. Kongera gusa ubwinshi, nko kongera umubare kuva mubice 3 kugeza kuri 5, ntabwo bizagira ingaruka zigaragara.

3. Simbuza igishushanyo cya grafite

Gupakira cyane PTFE bifite ubushyuhe bwo gukora murwego rwa -20 kugeza + 200 ° C. Iyo ubushyuhe buhindutse cyane hagati yimipaka yo hejuru no hepfo, imikorere yayo yo gufunga izagabanuka cyane, izasaza vuba kandi ubuzima bwayo bugufi.

Imiterere yuzuye ya grafite yuzuza izo nenge kandi zifite ubuzima burebure. Kubwibyo, inganda zimwe zahinduye gupakira PTFE zose zipakirwa kuri grafite, ndetse na valve yagenzuwe nshya yakoreshejwe nyuma yo gusimbuza ipaki ya PTFE hamwe no gupakira grafite. Nyamara, hystereze yo gukoresha grafite yuzuza ni nini, kandi rimwe na rimwe kunyerera bibaho mbere, kubwibyo bigomba kwitabwaho.

4. Hindura icyerekezo gitemba hanyuma ushire P2 kumpera ya valve.

Iyo △ P nini na P1 nini, gufunga P1 biragaragara ko bigoye kuruta gufunga P2. Kubwibyo, icyerekezo gitemba gishobora guhinduka kuva kuri P1 kumurongo wa valve kugera kuri P2 kumpera yumutwe wa valve, ibyo bikaba byiza cyane kumatara afite umuvuduko mwinshi hamwe nigitutu kinini. Kurugero, induru ya bellows igomba gutekereza kubifunga P2.

5. Koresha lens ya kashe

Kugirango ushireho igifuniko cyo hejuru no hepfo, gufunga intebe ya valve numubiri wo hejuru na hepfo. Niba ari ikidodo kiringaniye, munsi yubushyuhe bwinshi nigitutu kinini, imikorere ya kashe ni mibi, itera kumeneka. Urashobora gukoresha kashe ya lens kashe aho, ishobora kugera kubisubizo bishimishije.

6. Simbuza igikuta

Kugeza ubu, gaseke nyinshi zifunze ziracyakoresha imbaho ​​za asibesitosi. Ku bushyuhe bwinshi, imikorere ya kashe ni mibi kandi ubuzima bwa serivisi ni bugufi, butera kumeneka. Muri iki gihe, urashobora gukoresha gasketi yakomeretse, impeta "O", nibindi, inganda nyinshi zimaze gufata.

7. Kenyera ibitsike mu buryo bumwe kandi ushireho kashe ya gaseke

Muburyo bwo kugenzura ububiko bwa kashe hamwe na kashe ya “O”, mugihe hakoreshejwe gasketi yuzuye ifite deformasiyo nini (nkimpapuro zizunguruka), niba compression idahwitse kandi imbaraga zidasanzwe, kashe izangirika byoroshye, ihindagurika kandi ihindurwe. Bigira ingaruka zikomeye kumikorere ya kashe.

Kubwibyo, mugihe cyo gusana no guteranya ubu bwoko bwa valve, ibisebe byo guhunika bigomba gukomera muburyo bumwe (menya ko bidashobora gukomera icyarimwe). Byaba byiza mugihe igitereko cyinshi gishobora guhindurwa mukibabi cyoroshye, gishobora kugabanya byoroshye impengamiro no kwemeza gufunga.

8.Kongera ubugari bwubuso bwa kashe

Intebe ya valve iringaniye (nkibikoresho byacometse kumyanya ibiri yimyanya yimyanya ndangagitsina) ntigishobora kuyobora no kuyobora umurongo uhetamye ku ntebe ya valve. Iyo valve ikora, intoki ya valve igengwa nimbaraga zuruhande kandi zisohoka ziva mubyerekezo byinjira. Umwanya, nini nini ihuza ikinyuranyo cya valve, niko bikomeye cyane iyi ngingo imwe. Byongeye kandi, guhindura ibintu, kutibanda cyane, cyangwa gutondekanya ntoya ya kashe ya kashe ya kashe (muri rusange 30 ° chamfering for kuyobora) bizavamo kashe ya valve mugihe yegereje gufunga. Isura ya nyuma ya chamfered ishyizwe hejuru yikidodo cyintebe ya valve, bigatuma intandaro ya valve isimbuka iyo ifunze, cyangwa idafunze na gato, byongera cyane kumeneka.

Igisubizo cyoroshye kandi cyingirakamaro ni ukongera ubunini bwububiko bwa kashe ya valve, kugirango diameter ntoya yumutwe wanyuma wa valve ni 1 kugeza kuri 5 mm ntoya ugereranije na diameter yintebe, kandi ifite ubuyobozi buhagije bwo kwemeza ko valve intangiriro iyobowe nintebe ya valve kandi ikomeza guhuza neza neza.
