背景技术Background technique
卸料阀是用于粉体材料均匀出料的装置，卸料阀的阀体材质一般为非金属材质，故市面上卸料阀的阀体多为尼龙材质，但是，卸料阀的阀体为尼龙材质时容易造成电机轴与卸料阀的阀体打滑，进而出现电机转动而卸料阀的阀体不转的异常现象，因此需要对卸料阀进行监测，以确定卸料阀是否存在异常现象。The discharge valve is a device used for uniform discharge of powder materials. The valve body of the discharge valve is generally made of non-metallic material. Therefore, the valve body of the discharge valve on the market is mostly made of nylon. However, the valve body of the discharge valve When made of nylon, it is easy to cause the motor shaft and the valve body of the unloading valve to slip, and then the motor rotates but the valve body of the unloading valve does not rotate. Therefore, the unloading valve needs to be monitored to determine whether the unloading valve exists. Anomalies.
目前，一般通过监测卸料阀中阀体的出料口的压力、流量、温度以及震动等信息中的一种或者多种，确定出卸料阀是否正常工作。At present, it is generally determined whether the discharge valve is working normally by monitoring one or more of the pressure, flow, temperature, vibration and other information of the discharge port of the valve body in the discharge valve.
但是，这种监测方法，无法在卸料阀中阀体的出料口出现故障时立即预警，使得卸料阀中阀体的出料口产生积料现象，导致卸料阀的温度过高，从而使得燃点低的积料自然，发生火灾等危险情况。However, this monitoring method cannot provide an immediate warning when the outlet of the valve body in the unloading valve fails, causing material accumulation in the outlet of the valve body in the unloading valve, causing the temperature of the unloading valve to be too high. As a result, the accumulation of materials with low ignition point will naturally lead to dangerous situations such as fires.
