一、空心金属0型圈的特点空心金属O型圈是把薄壁不锈钢、蒙乃尔合金、镍铬铁耐热耐蚀合金等管料制成环状,将其两端焊接而成(断而直径为φ3.16毫米时,壁厚为0.25毫米),在合成橡胶O型圈不能胜任的高温、高压以及需要得到高真空的情况下,主要作为静密封使用。空心金属O型圈,其环的断面形状基本上以圆形为标准,但根据不同的使用目的,也制成椭圆形及近似于矩形的O型圈。这些断面为特殊形状的O型圈,强度上要求其弯曲半径约为管径的六倍左右。图1所示系断
First, the characteristics of hollow metal 0-ring Hollow metal O-ring is thin-walled stainless steel, Monel, nickel-chromium iron heat-resistant corrosion-resistant alloy pipe material made of a ring, welded at both ends (broken Diameter of φ3.16 mm, wall thickness of 0.25 mm), the synthetic rubber O-ring is not capable of high temperature, high pressure and the need to get a high vacuum case, mainly used as a static seal. Hollow metal O-ring, the ring shape of the cross-section of the circle is basically a standard, but according to different purposes, but also made oval and nearly rectangular O-ring. These cross-sections are specially shaped O-rings that require a bend radius of about six times the diameter of the pipe. Figure 1 shows off
