Valve y'amashanyarazi ya pulasitiki ishobora gufungwa neza gusa hakoreshejwe uburyo bwo kuzunguruka bwa dogere 90 n'imbaraga nto zo kuzunguruka. Umwobo w'imbere w'umubiri wa valve ungana neza utanga ubushobozi bwo kudahagarara no kunyura mu buryo bugororotse.
Muri rusange bifatwa nk'aho valve y'umupira ikwiriye cyane mu gufungura no gufunga mu buryo butaziguye, ariko iterambere riherutse gukorwa ryashyizeho valve y'umupira yo gufunga no kugenzura amazi. Ikintu cy'ingenzi kiranga valve y'umupira ni imiterere yayo nto, yoroshye kuyikoresha no kuyibungabunga, ikwiriye amazi, solvent, aside na gaze karemano n'ibindi bikoresho rusange bikora, ariko kandi ikwiriye no mu mikorere mibi y'ibikoresho, nka ogisijeni, peroxide ya hydrogen, methane na ethylene. Igice cy'icyuma cy'umupira gishobora kuba icy'ingenzi cyangwa gihujwe.
Umugozi w'umupira wakoreshejwe cyane mu mashami ya peteroli, imiti, gaze ivanze n'amazi, imiyoboro y'amazi n'imiyoboro y'amazi, ibiribwa, imiti, amashanyarazi, gukora impapuro, kubaka imijyi, amabuye y'agaciro, sisitemu y'umwuka w'amashyuza, umujyi, ingufu za atome, indege, roketi n'izindi, ndetse no mu buzima bwa buri munsi bw'abantu.
Valve y'amashanyarazi ya pulasitiki yahinduwe iva kuri valve ikoreshwa mu guterura. Ifite uburyo bumwe bwo guterura dogere 90, itandukaniro ni uko umubiri w'inyuma ari umupira, ufite umwobo unyura mu ruziga cyangwa umuyoboro unyura mu murongo wawo. Igipimo cy'ubuso bw'uruziga n'aho umuyoboro unyura kigomba kuba ku buryo iyo umupira uzenguruka dogere 90, aho usohoka n'aho unyura byose bigomba kuba uruziga, ku buryo bigabanya amazi.
Valve y'amashanyarazi ya pulasitiki ishobora gufungwa neza gusa hakoreshejwe uburyo bwo kuzunguruka bwa dogere 90 n'imbaraga nto zo kuzunguruka. Umwobo w'imbere w'umubiri wa valve ungana neza utanga ubushobozi bwo kudahagarara no kunyura mu buryo bugororotse.
Muri rusange bifatwa nk'aho valve y'umupira ikwiriye cyane mu gufungura no gufunga mu buryo butaziguye, ariko iterambere riherutse gukorwa ryashyizeho valve y'umupira yo gufunga no kugenzura amazi. Ikintu cy'ingenzi kiranga valve y'umupira ni imiterere yayo nto, yoroshye kuyikoresha no kuyibungabunga, ikwiriye amazi, solvent, aside na gaze karemano n'ibindi bikoresho rusange bikora, ariko kandi ikwiriye no mu mikorere mibi y'ibikoresho, nka ogisijeni, peroxide ya hydrogen, methane na ethylene.
Igice cy'umugozi wa valve y'umupira gishobora kuba icy'ingenzi cyangwa gihujwe. Ihame ry'imikorere n'uruhare rw'imikorere rwa valve y'umupira ya pulasitiki ikoreshwa n'amashanyarazi, ihame ry'imikorere rya valve y'umupira ni ugutuma valve ifungurwa cyangwa igafungwa ukoresheje kuzunguruka valve.
Itara ry'urumuri rw'umupira w'amashanyarazi, rito, rishobora gukorwamo umurambararo munini, gufunga neza, imiterere yoroshye, kubungabunga neza, gufunga ubuso n'ubuso bw'uruziga akenshi bifunze, ntabwo byoroshye kwangirika bitewe n'uburyo bwo gusohora, rikoreshwa cyane mu nganda zitandukanye.
Valve y'umupira wa pulasitiki ikoreshwa n'amashanyarazi na valve yo gushyiramo amashanyarazi ni bimwe mu bwoko bumwe bwa valve, igice cyayo cyo gufunga ni umupira gusa, kandi umupira uzenguruka umurongo wo hagati w'umubiri wa valve kugira ngo ufungure kandi ufunge valve. Valve y'umupira ikoreshwa cyane cyane mu guca, gukwirakwiza no guhindura icyerekezo cy'inzira y'amazi mu muyoboro. Valve y'umupira wa pulasitiki ikoreshwa cyane ni ubwoko bushya bwa valve bukoreshwa cyane mu myaka ya vuba aha.
Ifite ibyiza bikurikira:
1. Ubudahangarwa bw'amazi buke, ingano yabwo yo kudahangarwa ingana n'uburebure bumwe bw'igice cy'umuyoboro.
2. Imiterere yoroshye, ingano nto n'uburemere bworoheje.
3. Irakomeye kandi yizewe. Kuri ubu, ibikoresho byo gufunga bya valve y'umupira bikozwe muri pulasitiki ifite ubushobozi bwo gufunga neza, kandi byakoreshejwe cyane muri sisitemu yo gufunga.
4. Gukora byoroshye, gufungura no gufunga byihuse, kuva ku gufungura byuzuye kugeza ku gufunga byuzuye kugeza ku guzunguruka kwa dogere 90, byoroshye gukoreshwa mu gucunga kure.
5. Gusana byoroshye, imiterere yoroheje ya valve y'umupira, impeta yo gufunga yimukanwa, gusenya no gusimbuza byoroshye.
6. Iyo valve ifunguye cyangwa ifunze neza, ubuso bwo gufunga bw'umupira n'intebe ya valve buba butandukanyijwe n'ubwo buryo, kandi ubwo buryo ntibuzatera kwangirika k'ubuso bwo gufunga valve.
7. Ikoreshwa mu buryo bwinshi, kuva kuri milimetero nto kugeza kuri metero nyinshi, kuva kuri vacuum nyinshi kugeza kuri pressure nyinshi rishobora gushyirwaho.
Umugozi w'umupira ukoreshwa cyane cyane mu guhuza cyangwa kuziba inzira y'imiyoboro, cyane cyane mu bice bisaba gufungura no gufunga byihuse, nko gupakurura ibintu byihutirwa. Kubera imiterere yawo yoroshye, ibice bike, uburemere bworoheje n'imikorere myiza yo gufunga, ukoreshwa cyane
