Icyuma cyicaye cyacometse igizwe na cavit hagati yo gucomeka kumurongo.Uyu mwobo ufunzwe hepfo kandi ushyizwemo na kashe-inshinge ikwiranye hejuru.Ikidodo cyatewe mu cyuho, kandi valve igenzura munsi yatewe inshinge ibuza kashe gutembera mu cyerekezo kinyuranye.Ikidodo gisohoka kiva mu cyuho cyo hagati kinyuze mu mwobo wa radiyo mu mavuta yo kwisiga agera ku burebure bw'ubuso bw'icyicaro.

Kugirango ugabanye itara ryicyicaro gisanzwe cyamavuta yamashanyarazi,Icyuma cyicaye cyacometsebyavumbuwe kandi bikoreshwa cyane.Usibye ibiranga amavuta asanzwe ubricated plug valves, umuvuduko uringaniye wacometse kumashanyarazi nabyo bifite ibimenyetso bikurikira:

• 1. Iyo valve ifunguye, umuvuduko mucyumba cyo hasi cyumubiri wa valve uringanizwa numuvuduko wo hagati mumuyoboro.Amavuta yumuvuduko ukabije wamavuta mucyumba cyo hejuru atuma umubiri wacometse usunikwa hepfo, kandi ikinyuranyo gito kigaragara hagati yumucomeka wubuso hamwe nubuso bwa kashe yumubiri wa valve, urumuri rwumubiri uzunguruka rugabanuka neza.
• 2. Mugihe cy'ubushyuhe bwo hejuru, kwaguka k'umuriro w'icyuma birashobora kwakirwa no kuzamuka no kugwa.Amavuta yo kwisiga amavuta, nubwo gukoresha amavuta bishobora kugabanya bikwiye gufungura no gufunga, ariko birashobora kwanduza uburyo.Kubwibyo, amavuta yafunzwe yatoranijwe kubikorwa nyabyo byo gukora.
