Umuyagankuba wa pulasitike wamashanyarazi urashobora gufungwa cyane hamwe na dogere 90 yo kuzunguruka hamwe nu muriro muto. Umuyoboro wimbere uringaniye rwose wumubiri wa valve utanga imbaraga nkeya kandi unyuze hagati.
Mubisanzwe bifatwa ko umupira wumupira ubereye cyane gufungura no gufunga, ariko iterambere rya vuba ryashizeho umupira wumupira wo gutembera no kugenzura imigendekere. Ikintu nyamukuru kiranga imipira yumupira nuburyo bwubaka, gukora byoroshye no kubungabunga, bikwiranye namazi, solvent, acide na gaze naturel nibindi bitangazamakuru rusange bikora, ariko kandi bikwiranye nuburyo bubi bwakazi bwibitangazamakuru, nka ogisijeni, hydrogen peroxide, metani na Ethylene. Umubiri wa valve wumupira wumupira urashobora kuba intangarugero cyangwa uhujwe.
Umuyoboro w’umupira wakoreshejwe cyane muri peteroli, imiti, gazi y’amazi, gutanga amazi n’amazi, ibiryo, imiti, kubyara amashanyarazi, gukora impapuro, kubaka imijyi, amabuye y'agaciro, amashyanyarazi, komini, ingufu za kirimbuzi, indege, roketi n’andi mashami, ndetse n’ubuzima bwa buri munsi.
Umuyagankuba wumupira wumuriro wamashanyarazi uhindagurika uva mumashanyarazi. Ifite icyerekezo kimwe cyo kuzamura dogere 90, itandukaniro nuko umubiri winkoko ari umupira, hamwe nuruziga runyuze mu mwobo cyangwa umuyoboro unyuze mu murongo. Ikigereranyo cyubuso bwa serefegitura nicyambu cyumuyoboro kigomba kumera kuburyo mugihe umupira uzengurutse dogere 90, kwinjira no gusohoka byose bigomba kuba bifatanye, kugirango bigabanye imigezi.

Ikintu nyamukuru kiranga imipira yumupira nuburyo bwubaka, gukora byoroshye no kubungabunga, bikwiranye namazi, solvent, acide na gaze naturel nibindi bitangazamakuru rusange bikora, ariko kandi bikwiranye nuburyo bubi bwakazi bwibitangazamakuru, nka ogisijeni, hydrogen peroxide, metani na Ethylene.
Umubiri wa valve wumupira wumupira urashobora kuba intangarugero cyangwa uhujwe. Ihame ryakazi nuruhare rufatika rwumuriro wumuriro wa plastike amashanyarazi ihame ryakazi ryumupira wumupira nugukora valve idafunzwe cyangwa igahagarikwa no kuzenguruka valve.
Umucyo wumupira wumupira, ubunini buto, urashobora gukorwa mumurambararo munini, gufunga kwizewe, imiterere yoroshye, kubungabunga byoroshye, gufunga ubuso hamwe nubuso bwa serefegitura akenshi bifunze, ntibyoroshye kurandurwa nuburyo, bikoreshwa cyane mubikorwa bitandukanye.
Umuyagankuba wa pulasitiki wumuriro wamashanyarazi hamwe nugucomeka kumurongo nubwoko bumwe bwa valve, gusa igice cyacyo cyo gufunga ni umupira, kandi umupira uzunguruka kumurongo wo hagati wumubiri wa valve kugirango ufungure kandi ufunge valve. Umupira wumupira ukoreshwa cyane cyane mugukata, gukwirakwiza no guhindura icyerekezo cyogutwara imiyoboro. Amashanyarazi ya plastike yumuriro nubwoko bushya bwa valve ikoreshwa cyane mumyaka yashize.
Ifite ibyiza bikurikira:
1. Kurwanya amazi mato, coefficente yayo yo kurwanya iringana n'uburebure buke bw'igice cy'imiyoboro.
2. Imiterere yoroshye, ingano ntoya nuburemere bworoshye.
3. Birakomeye kandi byizewe. Kugeza ubu, ibikoresho byo gufunga umupira wa valve bikozwe muri plastiki bifite imikorere myiza yo gufunga, kandi byakoreshejwe cyane muri sisitemu ya vacuum.
4. Igikorwa cyoroshye, gufungura byihuse no gufunga, kuva gufungura byuzuye kugeza gufunga byuzuye igihe cyose 90 ° kuzunguruka, byoroshye kugenzura kure.
5. Kubungabunga byoroshye, imiterere yoroshye yumupira wumupira, impeta yimukanwa yimukanwa, gusenya byoroshye no gusimburwa.
6. Iyo valve ifunguye neza cyangwa ifunze, ubuso bwo gufunga umupira nintebe ya valve bitandukanijwe hagati, kandi uburyo ntibuzatera isuri yubuso bwa kashe.
7. Urutonde runini rwo gusaba, diameter kuva kuri milimetero nyinshi, kugeza kuri metero nyinshi, kuva mu cyuho kinini kugeza kumuvuduko mwinshi urashobora gukoreshwa.
Umupira wumupira ukoreshwa cyane cyane guhuza cyangwa guhagarika imiyoboro ikoreshwa, cyane cyane mubice bisaba gufungura no gufunga byihuse, nko gupakurura byihutirwa. Kubera imiterere yoroshye, ibice bike, uburemere bworoshye nibikorwa byiza byo gufunga, birakoreshwa cyane
