Gucomeka kumashanyarazi ni valve izenguruka muburyo bwo gufunga cyangwa plunger. Nyuma yo kuzunguruka dogere 90, umuyoboro ufungura kumugozi wa valve ni kimwe cyangwa utandukanijwe numuyoboro ufungura kumubiri wa valve kugirango urangize gufungura cyangwa gufunga. Ikoreshwa cyane mubucukuzi bwa peteroli, gutwara no gutunganya ibikoresho, kandi iyo mibande irakenewe no kuvanga asfalt.

Amacomeka ya plaque ya plug mumashanyarazi avanze ya asfalt arashobora kuba silindrike cyangwa conical. Muri plaque ya silindrike, umuyoboro muri rusange urukiramende; mumashanyarazi ya plaque, umuyoboro ni trapezoidal. Iyi shusho ituma imiterere yumucyo wacomwe kandi ikwiranye cyane no guhagarika no guhuza itangazamakuru no gutandukana.
Kubera ko urujya n'uruza ruri hagati yikidodo cya plaque ya valve ifite ingaruka zo guswera, kandi iyo ifunguye byuzuye, irashobora kwirinda rwose guhura nigikoresho kigenda, bityo rero irashobora gukoreshwa mubitangazamakuru bifite uduce duto twahagaritswe. Mubyongeyeho, ikindi kintu cyingenzi kiranga plug ya valve nuko byoroshye guhuza imiterere yimiyoboro myinshi, kuburyo valve imwe ishobora kubona imiyoboro ibiri, itatu, cyangwa enye zitandukanye, zishobora koroshya igenamigambi rya sisitemu. , gabanya ingano ya valve nibindi bikoresho bihuza bikenewe mubikoresho.
Gucomeka kumashanyarazi ya asfalt ivanga ibihingwa birakwiriye gukora kenshi kubera gufungura byihuse kandi byoroshye. Ifite kandi ibyiza byo kurwanya amazi mato, imiterere yoroshye, ingano ntoya, uburemere bworoshye, kubungabunga byoroshye, imikorere myiza yo gufunga, nta kunyeganyega, n urusaku ruke.
Iyo plaque valve ikoreshwa muguhuza ibiti bya asfalt, ntibizagabanywa nicyerekezo cyigikoresho, kandi icyerekezo cyo gutembera hagati gishobora kuba icyo aricyo cyose, ibyo bikaba biteza imbere ikoreshwa ryibikoresho. Mubyukuri, usibye urwego twavuze haruguru, valve yamashanyarazi irashobora kandi gukoreshwa cyane muri peteroli, imiti, gaze yamakara, gaze gasanzwe, gaze ya peteroli yamazi, imyuga ya HVAC ninganda rusange.
