| 真空球阀法兰连接 Flange Connection of Vacuum Ball Valve 这是阀门中用得最多的连接形式。按结合面形状又可分为以下几种： This is the most commonly used form of connection in valves. According to the shape of the joint surface, it can be divided into the following categories: 1）光滑式：用于压力不高的阀门。加工比较方便 1) smooth type: used for valves with low pressure. Processing is more convenient 2）凹凸式：工作压力较高，可使用中硬垫圈 2) Concave-convex type: high working pressure, medium-hard washer can be used 3）榫槽式：可用塑性变形较大的垫圈，在腐蚀性介质中使用较广泛，密封效果较好。 3) Tenon-groove type: gaskets with large plastic deformation can be used, which are widely used in corrosive media and have good sealing effect. 4）梯形槽式：用椭圆形金属环作垫圈，使用于工作压力≥64公斤/平方厘米的阀门，或高温阀门。 4) Trapezoidal groove type: use elliptical metal ring as washer for valves with working pressure greater than 64 kg/square centimeter or high temperature valves. 5）透镜式：垫圈是透镜形状，用金属制作。用于工作压力≥100公斤/平方厘米的高压阀门，或高温阀门。 5) Lens type: Washer is lens shape, made of metal. High-pressure valves or high-temperature valves with working pressure greater than 100 kg/m2. 6）O形圈式：这是一种较新的法兰连接形式，它是随着各种橡胶O形圈的出现，而发展起来的，它在密封效果上比一般平垫圈可靠。 6) O-ring type: This is a relatively new form of flange connection. It is developed with the emergence of various rubber O-rings, and its sealing effect is more reliable than that of ordinary flat gaskets. |
