Valve y'umupira w'umuriro w'umuryango w'igihugu
Ibindi bicuruzwa
I.Ibyerekeye Imiterere ya Valve yo Kwirinda Kuzunguruka ya Gikero
1. Ibicuruzwa byashizweho kandi byakozwe ukurikije icyongereza cya leta GB/T 12236, imiterere irimo neza, imashini irinda neza, kandi imikorere iri hejuru.
2. Imashini irinda imashini na imashini irinda imashini bikozwe mu buhanga bwo gushyiraho alloy ya iron cyangwa alloy ya cobalt ya stellite, irashobora kwirinda kwangirika, kwangirika kw’umuriro, kwangirika kw’umwuka, kandi irinda kwangirika neza, kandi igira ubuzima bw’igihe kirekire.
3. Birashobora gukoreshwa ibipimo bya flange byo gutera imashini no mu buryo bw’imashini irinda flange, kugirango uhuze ibyo abakora imirimo n’abakoresha bakeneye.
4. Ibikoresho bya valve byuzuye, imashini irinda imashini irashobora guhitamo neza ukurikije ibikorwa by’ukuri cyangwa ibyo abakoresha bakeneye, kandi birashobora gukoreshwa mu byiciro byo hejuru, ubushyuhe n’ibikoresho byo hejuru.
5. Imashini irinda imashini izunguruka ku gice cyo hanze ya valve, kugirango igabanye kwangirika kw’umutwe mugihe cyo guhagarika.
6. Icyo gikoresho cyo gusobanura imashini irinda imashini gikoresha imiterere yo hanze, nta gice cyo hanze cyo kwangirika, kandi ikoresha neza.
II.Ibyerekeyo Imashini Irinda Kuzunguruka ya Gikero: Ibipimo n’Ibyifuzo
Uburebure bw’umuvuduko PN (MPa): 1.6~16
Uburebure bw’umuvuduko w’umuvuduko w’umubiri: 1.5 times ya PN mu bushyuhe bwo hasi
Uburebure bw’umuvuduko w’umuvuduko w’imashini irinda imashini (MPa): 1.1 times ya PN mu bushyuhe bwo hasi
Uburebure bw’umuvuduko w’umuvuduko mu bushyuhe bwo hasi (MPa): ≤1.6~≤16
