Umupira, gufungura no gufunga umunyamuryango (umupira) itwarwa nigiti cya valve ikazenguruka hafi yumurongo wumupira wumupira. Irashobora kandi gukoreshwa mugutunganya amazi no kugenzura. Muri byo, icyuma gifunga umupira wa V gifunze cyane gifite imbaraga zo kogosha hagati yumupira wumupira wa V nicyicaro cyicyuma cyicyuma cyumubyimba ukomeye, kikaba kibereye cyane fibre nuduce duto duto. n'ibindi. Imipira myinshi-imipira yumupira kumuyoboro ntishobora kugenzura gusa guhuza, gutandukana, no guhinduranya icyerekezo gitemba hagati, ariko kandi irashobora gufunga umuyoboro uwo ariwo wose no guhuza indi nzira yombi. Ubu bwoko bwa valve bugomba gushyirwaho muburyo butambitse. Umupira wumupira ugabanijwemo: pneumatike yumupira wumupira, umupira wamashanyarazi, umupira wamaboko ukurikije uburyo bwo gutwara.

Ibiranga umupira wumupira:

1. Kurwanya kwambara; kuberako intandaro ya valve yibikoresho bifunze bifunze imipira ni alloy ibyuma spray gusudira,

Impeta yo gufunga ikozwe mu byuma bisobekeranye, bityo umupira wumupira ufunze cyane ntushobora kubyara imyenda myinshi iyo ifunguye kandi uzimye. (Ikintu gikomeye ni 65-70):

Icya kabiri, imikorere ya kashe ni nziza; kuberako ikidodo cyumupira gifunze gifunze nubutaka bwubukorikori, ntigishobora gukoreshwa kugeza igihe intoki ya valve nimpeta ifunze. Imikorere ye ya kashe rero ni iyo kwizerwa.

Icya gatatu, icyerekezo cyoroshye; kuberako hepfo yimpeta yikimenyetso cyumupira wumupira wafunzwe bifata isoko kugirango ifate impeta yikimenyetso hamwe na valve yibanze hamwe, icyerekezo cyoroshye cyane mugihe imbaraga zo hanze zirenze preload yimvura.

.

Umuyoboro wa pneumatike ufite imiterere yoroshye kandi yoroheje, gufunga byizewe no kubungabunga neza. Ubuso bwa kashe hamwe nubuso bwa serefegitura burigihe muburyo bufunze, butangirika byoroshye nuburyo bworoshye, kandi byoroshye gukora no kubungabunga. Irakwiriye kubitangazamakuru rusange bikora nkamazi, ibishishwa, aside na gaze gasanzwe. Ikoreshwa cyane cyane mugukata Cyangwa guhuza imiyoboro mumuyoboro, kandi irashobora no gukoreshwa mugutunganya no kugenzura amazi.

Ugereranije nubundi bwoko bwa valve, pneumatic ball valves ifite inguni ya stroke isohoka, gufungura byihuse, bihamye kandi byizewe, gukoresha mugari, hamwe nibyiza bikurikira:

1. Kwikuramo gusunika bigabanya umuvuduko wo guteranya uruti rwa valve, rushobora gutuma uruti rwa valve rukora neza kandi byoroshye.

.

3. Bitewe nuburyo bwiza bwo kwisiga bwa PTFE nibindi bikoresho, igihombo cyo guterana umupira ni gito, bityo ubuzima bwumurimo wumupira wumupira wa pneumatike ni muremure.

4. Ndetse kugabanuka-diameter pneumatic ball valve, irwanya amazi yayo ni nto cyane.

5.

6. Intebe ya valve ifite imikorere myiza yo gufunga: impeta yo gufunga ikozwe mubikoresho byoroshye nka PTFE byoroshye gufunga imiterere, kandi ubushobozi bwo gufunga umupira wa pneumatike bwiyongera hamwe no kwiyongera k'umuvuduko wo hagati.

7. Kurwanya amazi ni bito, kandi umupira wuzuye wuzuye umupira ntushobora kwihanganira umuvuduko.

8. Imiterere yoroshye, ubunini buto nuburemere bworoshye.

9. Komera kandi wizewe. Ifite ibice bibiri bifunga, kandi ibikoresho byo gufunga umupira wumupira bikoreshwa cyane muri plastiki zitandukanye, zifite imikorere myiza yo gufunga kandi zishobora kugera kashe. Yakoreshejwe kandi muri sisitemu ya vacuum.

10. Gukora byoroshye, gufungura byihuse no gufunga, valve yumupira ikenera gusa kuzunguruka 90 ° kuva ifunguye neza kugeza ifunze byuzuye, byoroshye kugenzura intera ndende.

11. Biroroshye kubungabunga, umupira wumupira ufite imiterere yoroshye, impeta yo gufunga muri rusange irimuka, kandi biroroshye gusenya no gusimbuza.

12. Iyo ifunguye byuzuye cyangwa ifunze byuzuye, hejuru yikimenyetso cyumupira hamwe nintebe ya valve bitandukanijwe hagati, kandi iyo imiyoboro inyuze, ntabwo bizatera isuri hejuru yikimenyetso cya valve.

13. Urutonde runini rwa porogaramu, diameter kuva kuri ntoya kugeza kuri milimetero nyinshi, nini kugeza kuri metero nyinshi, kandi irashobora gukoreshwa kuva mumyuka mwinshi kugeza kumuvuduko mwinshi.

14. Kuberako umupira wumupira ufite guhanagura ibintu mugihe cyo gufungura no gufunga, birashobora gukoreshwa hagati hamwe nuduce duto twahagaritswe.

15. Gutunganya neza neza nigiciro kinini. Ntibikwiye gukoreshwa mubushyuhe bwo hejuru. Niba hari umwanda mumuyoboro, biroroshye guhagarikwa numwanda, bigatuma valve idashobora gufungurwa.
