Umupira wumupira wa plastike wahindutse uva mumashanyarazi. Igice cyo gufungura no gufunga igice ni umuzenguruko, ukoresha umuzenguruko uzunguruka dogere 90 kuzenguruka umurongo wikibaho cya valve kugirango ugere ku ntego yo gufungura no gufunga. Umupira wumupira wa plastike urakenewe muguhuza inzira yo gutwara hamwe nuburyo bubora. Ukurikije ibikoresho bitandukanye, ubushyuhe bwakazi ni PVC 0 ℃～ 50 ℃, C-PVC0 ℃～ 90 ℃, PP -20 ℃～ 100 ℃, PVDF -20 ℃～ 100 ℃. Umuyoboro wumupira wa plastiki ufite imbaraga zo kurwanya ruswa. Impeta ya kashe ifata EPDM na FKM; ifite imbaraga zo kurwanya ruswa kandi ikongerera igihe cya serivisi. Guhinduranya byoroshye kandi byoroshye gukoresha. Umuyoboro wumupira wa plastike Umuyoboro wuzuye wumupira ufite ingingo nkeya ziva, imbaraga nyinshi, kandi ubwoko bwumupira wumupira bworoshye byoroshye guteranya no gusenya.

Umuyoboro wa plastiki wumupira ntiworoshye gusa muburyo bwiza, nibyiza mubikorwa byo gufunga, ariko kandi ni muto mubunini, urumuri muburemere, bike mukoresha ibikoresho, bito mubunini bwubushakashatsi, na bito mumashanyarazi atwara mumurongo runaka wa diameter. Nibyoroshye gukora kandi byoroshye kugera byihuse no gufunga. Bumwe mu bwoko bwihuta bwubwoko bwa valve mumyaka icumi ishize. By'umwihariko mu bihugu byateye imbere nka Amerika, Ubuyapani, Ubudage, Ubufaransa, Ubutaliyani, Uburengerazuba, n'Ubwongereza, gukoresha imipira y’umupira ni byinshi cyane, kandi ubwoko n'ubwinshi bikoreshwa biracyaguka.

Ihame ryakazi ryumupira wumupira wa plastike nugukora valve idafunzwe cyangwa igahagarikwa mukuzunguruka uruti. Guhindura biroroshye, bito mubunini, byizewe mukidodo, byoroshye mumiterere kandi byoroshye kubungabunga. Ubuso bwa kashe hamwe nubuso bwa serefegitura akenshi biba bifunze kandi ntibishobora kwangirika byoroshye. Ikoreshwa cyane mu nganda zitandukanye.

Umupira wumupira nubwoko bushya bwaindangayakoreshejwe cyane mu myaka yashize. Ifite ibyiza bikurikira:

1. Kurwanya amazi ni bito, kandi coefficente yayo irwanya ihwanye nigice cyumuyoboro ufite uburebure bumwe.

2. Imiterere yoroshye, ubunini buto nuburemere bworoshye.

3. Birakomeye kandi byizewe. Kugeza ubu, ibikoresho byo hejuru bifunga umupira wa valve bikoreshwa cyane muri plastiki bifite imikorere myiza yo gufunga, kandi byanakoreshejwe cyane muri sisitemu ya vacuum.

4. Igikorwa cyoroshye, gufungura byihuse no gufunga, gusa bigomba kuzunguruka 90 ° kuva byuzuye kugeza bifunze byuzuye, byoroshye kugenzura kure.

5. Kubungabunga neza, imiterere yoroshye yaumupira wamaguru, impeta yo gufunga muri rusange irimuka, biroroshye gusenya no gusimbuza.

6. Iyo ifunguye neza cyangwa ifunze byuzuye, ubuso bwo gufunga umupira hamwe nintebe ya valve bitandukanijwe hagati, kandi uburyo ntibuzatera isuri yubuso bwa kashe iyo igikoresho cyanyuze.

7. Ifite intera nini yo gusaba, hamwe na diameter kuva kuri milimetero nkeya kugeza kuri metero nkeya, kandi irashobora gukoreshwa kuva mumyuka mwinshi kugeza kumuvuduko mwinshi.
