LIT力特『进口气动刀闸阀』详细介绍●LIT气动阀系列●LIT气动刀闸阀●产品数据
进口气动刀闸阀描述--
LIT气动刀闸阀分为上下两部分，上半部分为气动执行器，下半部分为刀阀,其结构可以做成硬密封、软密封，与气动执行器辅助配合,利用气动执行器控制阀门，从而实现阀门的开和关的一种阀门
LIT pneumatic knife gate valve is divided into two parts, the upper part is pneumatic actuator, the lower part is the knife valve, its structure can be made into hard seal, soft seal, auxiliary coordination with pneumatic actuator, using pneumatic actuator to control the valve, so as to realize the valve opening and closing a valve.
进口气动刀闸阀附件选择--
1.回讯器：亦称限位开关，反馈开关信号(反馈是否开到位或关到位),普通型或防爆型;
2.电磁阀：双作用选二位五通、单作用选二位三通(普通型或防爆型)
3.气源处理三联件：过滤器、减压阀、油雾分离器,可气源起稳压、过滤作用(普通型或防爆型)
4.电-气：输入4～20mA信号,实现阀门调节功能;
5.手轮机构：在气源故障或停电情况下，转动手轮机构，可实现手动开、关阀;
进口气动刀闸阀典型应用--
刀闸阀具有切断介质的优点，其密封原理是通过闸板在关闭到底时，闸板斜切面碰到阀体上的锲块使得闸板紧靠密封面起到密封效果，并且闸板底部的斜切面具有切断介质的功能，使得阀门不易受介质的堵塞卡阻,主要适用于矿山电厂的选煤、排渣、食品、造纸、医药、化工等管路上，接通或截断管路中的水泥浆、金矿粉、矿砂、炉渣、煤泥、纸浆、木浆、尾矿、纤维、粉尘、***处理污水、沉淀池、沥青、料仓出口等介质。
The knife gate valve has the advantage of cutting the medium, and its sealing principle is that the sluice board is closed to the valve body when the gate is closed to the end, which mes the gate close close to the sealing surface to seal the effect, and the oblique section at the bottom of the gate has the function of cutting the medium, so that the valve is not easily blocked by the medium. It is mainly applicable to the mine. The coal preparation, slag, food, paper, medicine, chemical and other pipelines of the mountain power plant are used to connect or cut off the cement slurry, gold powder, ore, slag, slime, pulp, pulp, tailings, fiber, dust, chemical treatment sewage, sedimentation tank, asphalt, silo outlet and other medium.
