Can You Lump Globe Valves & Gate Valves Together?
2021-08-11
答案绝对是否!在结构中,如果空间有限,则栅极阀取决于中等压力来紧密密封表面,以达到无泄漏的效果。打开和关闭时,圆盘和座椅密封表面始终接触并互相摩擦,这会导致磨损的密封表面。当栅极即将关闭时,管道前后的压力差很大,这也会导致密封表面损坏更为严重。栅极的结构比地球阀的结构更为复杂。就形状的阀门阀比球阀高,假设它们具有相同的口径。此外,门阀的茎分为两类,上升或不升高,而Globe Valve的茎则不属于。工作原理地球阀用升起的茎张开和关闭,这意味着,当手轮转动时,手轮将与茎上和向下移动。至于闸阀,手轮转动,茎上和向下移动,但手轮本身保持在同一位置。它们的流量各不相同。 Gate valves have to be full opened or closed, while globe valves do not. Globe valves have a defined inlet and outlet direction, while gate valves do not. In addition, the gate valve has only two states: fully open or fully closed,and the long travel of the disc results in a longer switching time.The time a globe vale needs is muchshorter. Most importantly, thedisc of the globe valve can stop at a certain place inthe valve body to do flow regulation. The gate valve can only be used for cut-off and has nosuch function. Performance differences Globe valves can be used for both cut-off and flow regulation. The fluid resistance of globe valve is relatively high, and it takes more effort to open and close, but because the distance between the valve plate and the sealing surface is short, the opening and closing stroke is short. When gate valve is fully open, the medium flow resistance in the valve body channel is almost 0, so the gate valve opening and closingwon’t be very laborious. But the gate plate is far from the sealing surface, opening and closing time is longer.
