Description

Technical Field

[0001] The utility model relates to the technical field of pressure reducing valve measurement, in particular to an intelligent pressure reducing valve measurement device. Background Art

[0002] Currently, with the continuous improvement of industrial automation, the requirements for fluid control systems are also increasing. As an indispensable component in fluid control, the performance of the pressure reducing valve directly affects the stability and efficiency of the entire system. With technological advancements and expanding market demand, its performance and application scope will continue to be optimized and expanded. The remote intelligent pressure reducing valve has a remote adjustment and control function. Through remote control, it can monitor and adjust the system pressure in real time, ensuring the system maintains stable operation under various operating conditions. Especially in industrial processes that require precise pressure control, the role of remote control pressure reducing valves is particularly important, helping companies achieve production automation control and improve production efficiency and product quality.

[0003] The working principle of a pressure reducing valve is to change the cross-sectional area through which the fluid passes, thereby controlling the fluid pressure, primarily by adjusting the valve opening. When the inlet pressure or flow rate changes, the pressure reducing valve can automatically adjust to maintain a stable outlet pressure. This self-regulating capability enables the pressure reducing valve to maintain good operating performance under a variety of working conditions. Intelligent pressure reducing valves can be remotely controlled using PCs and mobile phones to achieve real-time monitoring and control of the pressure reducing valve. Whether the intelligent pressure reducing valve can meet the intelligent regulation and control requirements, and whether it can stably control flow, pressure, and time, thereby achieving stable control of pipeline flow and pressure, maintaining stable fluid flow and pressure during the production process, and improving production efficiency and product quality is particularly important.

[0004] To this end, we have developed an intelligent pressure reducing valve measuring device to solve the above problems. Utility Model Content

[0021] Figure 1 and Figure 2 A device for testing an intelligent pressure reducing valve comprises a housing 1 and a test hatch 6, which are fixedly connected in sequence. A water inlet 8 and a main switch 9 are provided at one end of the test hatch 6, sequentially arranged from top to bottom. The water inlet 8 is connected to an external water pipe or water tank 13. An intelligent controller display 2 is provided on one side of the housing 1 in the longitudinal direction. An intelligent controller 11 is provided on the inner wall of the intelligent controller display 2, and a motor 14 is provided on the lower side. The intelligent controller controls a water pump through the motor to perform a water circulation test. A water tank 13 is provided at the inner bottom end of the test hatch 6. The top of the water tank 13 is connected in sequence to a remote transmission pressure gauge 16 and a water outlet electric contact pressure gauge 17. A shut-off valve 15 is connected in parallel between the remote transmission pressure gauge 16 and the water tank 13. The water inlet 8 is connected in sequence to a water pump 22, an electromagnetic flowmeter 20, and a water inlet electric contact pressure gauge 19. An intelligent pressure reducing valve 18 is fixedly connected between the water outlet electric contact pressure gauge 17 and the water inlet electric contact pressure gauge 19. The intelligent pressure reducing valve 18 is tested through the setting of the intelligent controller.

[0022] The lower side of the housing 1 is equipped, from top to bottom, with a flow control 3, a pressure control 4, and a time control 5. Each of these is electrically connected to an intelligent controller 11. The intelligent controller 11 features a time zone and time setting interface, displaying at least four time zones. A relay 12 is located on one side of the bottom of the intelligent controller 11 and is electrically connected to the intelligent controller 11. The relay controls the time of the intelligent controller.

[0023] A timing controller 23 is located below the main switch 9 and is fixedly connected to the test chamber door 6. A test chamber switch 7 is located along one side of the test chamber door 6. Two rollers 10 are located at the bottom of the test chamber door 6 and the bottom of the housing 1. This means that a roller 10 is located at each of the four corners of the bottom of the measuring device to facilitate its movement.

[0024] To facilitate connection and testing of both sides of the intelligent pressure reducing valve, one end of the intelligent pressure reducing valve 18 is fixedly connected to an inlet pipe 21, and the other end is fixedly connected to an outlet pipe 211.

[0026] Install the intelligent pressure reducing valve on the test water pipe of the intelligent regulation performance test device. While maintaining the water supply pressure at a constant pump pressure, adjust the outlet pressure of the intelligent pressure reducing valve to the set pressure value at zero flow. In time-pressure regulation mode, slowly open the shutoff valve. Set four time periods and their durations on the intelligent controller interface, setting different outlet pressures for each period. Record whether the actual outlet pressure of the pressure reducing valve automatically adjusts to the corresponding set pressure within each period. In flow-pressure regulation mode, set four flow intervals on the intelligent controller interface, each with a different outlet set pressure. First, slowly open the shutoff valve, gradually increasing the flow rate to intervals 1, 2, 3, and 4. Observe whether the actual outlet pressure of the pressure reducing valve automatically adjusts to the corresponding set pressure within each flow interval. Then, slowly close the shutoff valve, gradually decreasing the flow rate to intervals 4, 3, 2, and 1. Observe whether the actual outlet pressure of the pressure reducing valve automatically adjusts to the corresponding set pressure within each flow interval.
