Description
Technical Field
[0001] The present invention relates to the technical field of solenoid valves, and in particular to an intelligent solenoid valve with precise control. Background Art
[0002] A solenoid valve is an industrial device controlled by electricity magnetism. It is a basic automation component for controlling fluids and belongs to an actuator. It is mainly used in industrial control systems to adjust parameters such as the direction, flow rate, speed, and other parameters of the medium. However, currently, it is impossible to accurately obtain the flow rate of the medium flowing through the solenoid valve based on the solenoid valve structure, so precise control cannot be achieved according to the conveying situation. Summary of the Invention
[0003] Aiming at the defects in the prior art, the present invention provides an intelligent solenoid valve with precise control.
[0004] An intelligent solenoid valve with precise control, comprising a mounting body. A pipeline inlet is provided on the right side of the mounting body, and a first mounting groove is provided on the top surface of the mounting body. A first valve body is arranged in the first mounting groove, and the first valve body encloses the first mounting groove to form a closed first mounting cavity. A first outlet is provided on the front side of the mounting body, and the pipeline inlet is connected to the first mounting cavity through a liquid inlet pipeline arranged in the mounting body. The first mounting cavity is connected to the first outlet through a first detection pipeline vertically arranged in the mounting body. Among them, a second outlet is also provided on the front side of the mounting body, and a second mounting groove is also provided on the top surface of the mounting body. A second valve body is arranged in the second mounting groove, and the second valve body encloses the second mounting groove to form a closed second mounting cavity. The second mounting cavity is connected to the end of the first detection pipeline through a transition pipeline arranged in the mounting body, and the second mounting cavity is connected to the second outlet through a second detection pipeline vertically arranged in the mounting body. The first valve body is used to receive a control signal and open or close the interface between the first mounting cavity and the first detection pipeline according to the control signal. The second valve body is used to receive a control signal and open or close the interface between the second mounting cavity and the second detection pipeline according to the control signal. A first flow detection probe extending into the interior of the first detection pipeline and a second flow detection probe extending into the interior of the second detection pipeline are penetrated through the mounting body. The first flow detection probe and the second flow detection probe are electrically connected to a control module for sending control signals. When in use in the whole intelligent solenoid valve, the pipeline inlet is connected to the medium input, and the medium flows through the liquid inlet pipeline, the first mounting cavity, the first valve body, the first detection pipeline and the first outlet in sequence. At this time, when the first outlet is opened, the medium can directly flow out from the first outlet. The whole intelligent solenoid valve only performs flow detection through the first detection pipeline between the first valve body and the first outlet. Specifically, the first flow detection probe detects the medium flowing in the first detection pipeline. The first flow detection probe can perform differential pressure detection and install a throttling device in the first detection pipeline to achieve flow detection. The whole first detection pipeline is vertically arranged, and the medium flow in it is uniform and stable, improving the flow detection effect. At the same time, under the control of the first valve body, the first detection pipeline can be switched on and off in a timely and accurate manner, thereby forming a fast and precise control feedback loop, improving the detection accuracy. At the same time, after disconnecting the first detection pipeline, the first flow detection probe can be quickly removed for maintenance, further improving the detection reliability of the first flow detection probe. Further, when the medium flow rate in the intelligent solenoid valve is too fast, the first outlet can be closed to allow the medium to flow into the transition pipeline from the first detection pipeline, and then flow through the second mounting cavity, the second valve body, the second detection pipeline and the second outlet in sequence. As described above, the second flow detection probe also has an environment and conditions for precise detection. After being used in cooperation with the first flow detection probe, data analysis and processing are performed on the detection results of the two, greatly improving the detection accuracy when the medium is flowing at a high speed and meeting the precise control of the conveying medium process under special circumstances.

Similarly, when the second sliding sleeve is sleeved around the second convex block, the second detection pipeline is not connected to the second installation cavity, and when the second sliding sleeve disengages from the second convex block, the second detection pipeline is connected to the second installation cavity.

Similarly, the height of the entire second limiting head determines the maximum relative distance between the second valve core and the second limiting head, that is, determines the maximum displacement of the second valve core. The setting of the maximum displacement satisfies that the second valve core can be disengaged from the second convex block by 2-3 cm after moving the maximum displacement.
