Description

Technical Field

[0001] The utility model relates to the technical field of flow detection, in particular to a detection system of a flow quantitative control cabinet. Background Art

[0002] A flow quantitative control cabinet is a device used to precisely control fluid flow. It can control processes such as quantitative metering, quantitative filling, and quantitative dosing of fluids. This equipment is widely used in chemical, petroleum, food, pharmaceutical, and water treatment industries to ensure the accuracy and continuity of the production process. Since the flow quantitative control cabinet itself is equipped with flow sensors and quantitative controllers, the flow sensors are used to monitor the flow of the fluid in real time, and the quantitative controllers are used to control according to preset flow values. If the above sensors and controllers are damaged, the precise control steps cannot be performed. At this time, external detection equipment is required to test whether the flow quantitative control cabinet is in normal working condition and whether its internal sensor controller is damaged.

[0003] After searching, no detection equipment dedicated to flow quantitative control cabinets was found, so the utility model proposes a special equipment for detecting the working performance of flow quantitative control cabinets. Utility Model Content

[0017] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figure 1 To the attached Figure 3 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the accompanying drawings.

[0018] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. Example

[0019] A detection system for a flow quantitative control cabinet includes an equipment base plate, an installation shell is fixedly provided above the equipment base plate, an outwardly extending detection liquid inlet interface is provided on the outer wall of the right side of the installation shell, a liquid inlet pipe is provided inside the detection liquid inlet interface, and the detection liquid inlet interface is used to connect the flow quantitative control cabinet to be detected. The liquid passing through the flow quantitative control cabinet is transported to the monitoring system and input into the equipment through the liquid inlet pipe.

[0020] One end of the liquid inlet pipe is provided with an inlet side filter fixed to the inside of the installation shell. After the liquid passes through the inlet side filter, the inlet side filter can perform a filtering step on the liquid from the outside. The upper end of the inlet side filter is provided with a first connecting pipe connected to it, and the other end of the first connecting pipe is provided with a second connecting pipe connected to the connecting pipe. The liquid passes through the first connecting pipe and the second connecting pipe in sequence and is transported backward.

[0021] It is further provided that a horizontally installed cleaning and maintenance pipe is provided at the upper end of the interior of the installation shell, one end of the cleaning and maintenance pipe extends outward from the interior of the installation shell, and one end of the cleaning and maintenance pipe is provided with a sealing cover threadedly connected to the pipe mouth, and the other end of the cleaning and maintenance pipe is connected to the connection between the first connecting pipe and the second connecting pipe. In the working state, the sealing cover is screwed onto the cleaning and maintenance pipe, and it is necessary to ensure the smooth flow of liquid from the first connecting pipe to the second connecting pipe. The cleaning and maintenance pipe mainly plays a role in daily maintenance. When the system needs to be maintained, the sealing cover needs to be unscrewed and put on the liquid inlet pipe. At this time, by passing cleaning water into the cleaning and maintenance pipe, the cleaning water will flow along the system pipeline and bring out impurities and dirt in the system pipeline to prevent the system pipeline from being blocked and affecting the test results.

[0022] A second solenoid valve is provided in the pipeline of the second connecting pipe. The second solenoid valve is installed at the front end of the two groups of detection modules. Here, the second solenoid valve is mainly used to control the overall on-off of the system pipeline.

[0023] Two sets of detection modules arranged in parallel are provided in the pipeline of the second connecting pipe. Both sets of detection modules are placed at the front end of the main flow meter. The detection modules specifically include a shunt joint, a first solenoid valve, and a branch flow meter. The shunt joint is fixed to the second connecting pipe. The first solenoid valve is arranged between the branch flow meter and the shunt joint. The branch flow meter is installed on one side of the main flow meter.

[0024] The pipelines of the two groups of detection modules are designed in parallel, and both are controlled by an independent first solenoid valve. During normal testing, it is not necessary to open both groups of detection modules at the same time. Only one group of detection modules needs to be opened, and the other group of detection modules can be used as a reference step for repeated tests to reduce test errors and improve the accuracy of test results. When the liquid flows through the detection module, the branch flowmeter performs a measurement, and a total flowmeter is also provided in the pipeline of the second connecting pipe. The total flowmeter is arranged at the rear end of the two groups of detection modules. External connecting pipes are provided at the end positions of the two groups of detection modules. The lower ends of the external connecting pipes are fixed above the bottom plate of the equipment. The external connecting pipes are all connected to the total flowmeter, and the external connecting pipes play a role of support and reinforcement. After passing through the pipeline of the detection module, the liquid will come to the total flowmeter. The total flowmeter plays a role of secondary measurement, which improves the measurement accuracy.

[0025] One side of the total flow meter is provided with a liquid outlet pipe connected to the second connecting pipe. A liquid collecting tank is provided directly below the liquid outlet pipe. A weight sensor fixed above the bottom plate of the equipment is provided below the liquid collecting tank. The liquid will fall into the liquid collecting tank after flowing out. The weight sensor below the liquid collecting tank can detect the weight change of the liquid in the liquid collecting tank. According to the relationship between the time change and the weight change, the flow rate of the liquid flowing out of the system can be obtained. When used in conjunction with the total flow meter and the branch flow meter, the measurement results can be further obtained to determine whether the external flow quantitative control cabinet is working stably.

[0026] The above is a further detailed description of the present invention in combination with a specific implementation method, and it cannot be determined that the specific implementation of the present invention is limited to this. For technical personnel in the field of the present invention and related technical fields, based on the technical solution of the present invention, any expansion and replacement of operating methods and data should fall within the scope of protection of the present invention.
