一种电磁阀控制的多量程压力检测装置
摘要：
本发明公开了一种电磁阀控制的多量程压力检测装置，包括压力发生设备、保压缸、稳压缸、第二电磁阀、增压器和压力检测装置输出口；压力发生设备的输出端与保压缸的输入端连接，保压缸的输出端与稳压缸的输入端连接，稳压缸的输出端与第二电磁阀的输入端连接，第二电磁阀的第一输出端与压力检测装置输出口连接，第二电磁阀的第二输出端与增压器的输入端连接，所述增压器的输出端与压力检测装置输出口连接。本发明通过第二电磁阀选择不同的通路，当需要大压力时，选择连接增压器的通路，通过增压器增大压力输出，使得压力的输出范围变宽，避免了购置多台压力检测装置，降低了成本。
摘要（英）：

The invention discloses a multi-range pressure detection device controlled by an electromagnetic valve, comprising pressure generation equipment, a pressure maintaining cylinder, a pressure regulating cylinder, a second electromagnetic valve, a supercharger, and a pressure detection device output port. The output end of the pressure generation equipment is connected with the input end of the pressure maintaining cylinder. The output end of the pressure maintaining cylinder is connected with the input end of the pressure regulating cylinder. The output end of the pressure regulating cylinder is connected with the input end of the second electromagnetic valve. A first output end of the second electromagnetic valve is connected with the pressure detection device output port. A second output end of the second electromagnetic valve is connected with the input end of the supercharger. The output end of the supercharger is connected with the pressure detection device output port. Different paths are selected through the second electromagnetic valve. When a large pressure is needed, a path connected with the supercharger is selected. The pressure output is increased through the supercharger, and the output range of pressure is wider. Thus, the purchase of a plurality of pressure detection devices is avoided, and the cost is reduced.
