Description
(一)技术领域(1) Technical field
本实用新型涉及一种液体流量控制装置，特别涉及一种用于生产炸药的乳化过程的液体流量控制装置。The utility model relates to a liquid flow control device, in particular to a liquid flow control device used in the emulsification process of producing explosives.
(二)背景技术(2) Background technology
在炸药的生产过程中，需要制造一种乳化基质，它由水相和油相两种液体混合而成，由于水相和油相液体组分的比例对其性能影响很大，所以在生产的乳化过程中两种液体必须维持在一定的流量范围内，并且精确地保证两种液体流量的比例关系，否则将影响成品的质量。目前，普遍采用的控制方法是分别在水相和油相两种液体流经的管道中安装精密的流量计，然后由自动控制装置根据流量计检测的水相和油相两种液体的流量值，通过安装在管道中的电动执行阀门调节水相或油相的流量大小，以保证水相和油相维持精确的比例关系；这种流量控制装置在控制过程中，有一定的时间滞后，难以保证水相和油相精确的比例关系，其主要原因是当水相和油相两种液体的流量变化比较频繁时，流量控制装置需要频繁地调节电动执行阀门，在这个过程中水相和油相两种液体流量的比例将难以维持在精确的数值。为了克服上述技术存在的问题，在专利号为00228745.5的中国实用新型专利中公开了一种“生产乳化炸药的乳化过程液体流量控制装置”，这种装置由与油相液体储罐、水相液体储罐、乳化器相连接的油相计量泵和水相计量泵组成，由于油相计量泵与水相计量泵可以稳定地定量输送油相及水相液体，所以该装置工作稳定性较好，控制精度较高；但是该液体流量控制装置亦存在有待改善之处，亦即是仍未对计量泵设置调节结构，计量泵不能根据实际流量进行微调以进一步提高流量的控制精度。In the production process of explosives, it is necessary to manufacture an emulsified matrix, which is composed of two liquids, the water phase and the oil phase. Since the ratio of the liquid components of the water phase and the oil phase has a great influence on its performance, it is During the emulsification process, the two liquids must be maintained within a certain flow range, and the proportional relationship between the two liquid flows must be accurately guaranteed, otherwise the quality of the finished product will be affected. At present, the commonly used control method is to install precision flowmeters in the pipelines through which the two liquids of the water phase and the oil phase flow, and then the automatic control device detects the flow values of the two liquids of the water phase and the oil phase according to the flowmeter. , adjust the flow rate of the water phase or oil phase through the electric actuator valve installed in the pipeline to ensure that the water phase and the oil phase maintain a precise proportional relationship; this flow control device has a certain time lag in the control process, which is difficult The main reason for ensuring the precise proportional relationship between the water phase and the oil phase is that when the flow rates of the water phase and the oil phase change frequently, the flow control device needs to frequently adjust the electric actuator valve. During this process, the water phase and the oil phase The ratio of the two liquid flows will be difficult to maintain at precise values. In order to overcome the problems of the above-mentioned technologies, a Chinese utility model patent No. 00228745.5 discloses a "liquid flow control device for the emulsification process in the production of emulsion explosives". The oil-phase metering pump and the water-phase metering pump connected to the storage tank and the emulsifier are composed. Since the oil-phase metering pump and the water-phase metering pump can stably and quantitatively transport the oil-phase and water-phase liquids, the device has good working stability. The control precision is high; however, the liquid flow control device still needs to be improved, that is, the metering pump has not yet been provided with an adjustment structure, and the metering pump cannot be fine-tuned according to the actual flow rate to further improve the flow control accuracy.
