在铸工车间煤粉粘上沸腾压送系统中,胶胆阀是常用部件。与手动闸阀和电动闸阀相比,它具有体积小、结构简单、操作方便、易于实现自动控制等优点,尤其在远距离压送和多点卸料时,上述优点更为显著。但是,由于结构上的原因,这种阀在实际使用中也暴露出自身存在的缺陷。图1是一胶胆阀实例。在装配过程中,法兰突出的斜面容易将胶胆挤退,使胶胆在阀中固定不可靠。工作时,压缩空气进入阀体气腔
In the caster workshop pulverized coal feed pressure boiling system, the plastic gallbladder valve is a common component. Compared with the manual gate valve and electric gate valve, it has the advantages of small size, simple structure, easy operation, easy to realize automatic control, etc., especially in the long-distance pressure delivery and multi-point discharge, the above advantages are more significant. However, due to structural reasons, such valves also expose their own defects in actual use. Figure 1 is a gall bladder valve example. In the assembly process, the flange protruding ramp easily squeeze the rubber gall bladder, gall bladder in the valve fixed unreliable. Working hours, compressed air into the body cavity
