Detailed Implementation

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Reference Figure 1 and Figure 2 As shown, a solenoid valve body throughput testing device includes a test bench 1, and a test chamber 2 is provided at the upper end of the test bench 1.

[0021] The test chamber 2 includes an inlet pipe 201 and an outlet pipe 202 fixedly connected to the upper end of the test bench 1 via a pipe support. A solenoid valve mounting seat 3 is fixedly connected between the inlet pipe 201 and the outlet pipe 202 via a connecting flange. A one-way valve 4 is fixedly connected to the end of the inlet pipe 201 away from the solenoid valve mounting seat 3. A plunger pump 5 is fixedly connected to the other end of the one-way valve 4. A flow sensor 8 is fixedly connected to the end of the outlet pipe 202 away from the solenoid valve mounting seat 3. A connecting pipe 9 is fixedly connected to the other end of the flow sensor 8. A pressure regulating valve 10 is fixedly connected to the other end of the connecting pipe 9. An outlet pressure sensor 14 and an inlet pressure sensor 13 are respectively installed on the connecting pipe 9 and the inlet pipe 201. An electric heating sleeve 16 is fitted on the outer surface of the inlet pipe 201.

[0022] Furthermore, the solenoid valve mounting base 3 is provided with flange interfaces at both ends for connecting to the inlet pipe 201 and the outlet pipe 202. A mounting hole matching the solenoid valve body is opened in the middle for docking with the solenoid valve. After the solenoid valve is installed, the solenoid valve can be fixed by tightening the bolts in the mounting hole. The model of the solenoid valve mounting base 3 can be replaced with the model of the solenoid valve to be tested as needed.

[0023] Furthermore, a servo motor 15 is fixedly installed on the upper end of the test bench 1. The output end of the servo motor 15 is fixedly connected to the input shaft of the plunger pump 5 through a coupling. A water supply pipe 6 is fixedly connected to the liquid inlet end of the plunger pump 5, and a water tank 7 is fixedly connected to the other end of the water supply pipe 6.

[0024] Furthermore, the servo motor 15 is used to drive the operation of the plunger pump 5. By adjusting the speed of the servo motor 15, the discharge volume and outlet pressure of the plunger pump 5 can be precisely controlled to achieve continuous pressure regulation. The plunger pump 5 draws fluid from the water tank 7, and after pressurization, it delivers the fluid to the inlet pipeline 201 through the check valve 4, providing a power source for the entire test system and enabling the fluid to flow in the pipeline, thereby testing the solenoid valve body. The check valve 4 can prevent fluid backflow, protect the plunger pump 5 from reverse pressure impact, and improve system safety.

[0025] Furthermore, the heating mantle 16 is a detachable silicone rubber heating mantle that wraps around the outer surface of the inlet pipe 201. It has a built-in thermocouple temperature sensor and is fixed to the outside of the inlet pipe 201 with Velcro. It can heat the test fluid to simulate high-temperature conditions, allowing the solenoid valve body under test to be tested in different temperature environments to evaluate its performance in high-temperature environments. Its built-in thermocouple temperature sensor can monitor the heating temperature in real time to ensure accurate control of the heating temperature.

[0026] Furthermore, the end of the pressure regulating valve 10 furthest from the connecting pipe 9 is fixedly connected to a water outlet pipe 11, and the other end of the water outlet pipe 11 is fixedly connected to a waste liquid collection tank 12.

[0027] Furthermore, both the water tank 7 and the waste liquid collection tank 12 are fixedly connected to the upper end of the test bench 1.

[0028] Furthermore, the flow sensor 8 can monitor the fluid flow rate after passing through the solenoid valve body under test in real time, and is used to evaluate the flow performance of the solenoid valve body.

[0029] Furthermore, the inlet pressure sensor 13 is vertically installed on the side wall of the inlet pipe 201, and the outlet pressure sensor 14 is installed on the side wall of the connecting pipe 9, for synchronously collecting inlet and outlet pressure data, calculating pressure loss, and evaluating the flow resistance characteristics of the solenoid valve body.

[0030] Furthermore, the pressure regulating valve 10 is an electric proportional regulating valve. By adjusting the valve opening, the flow cross-sectional area of ​​the fluid is changed, thereby regulating the outlet back pressure. By adjusting the outlet back pressure and cooperating with the pressure regulation of the plunger pump 5, the pressure difference between the inlet and outlet of the solenoid valve body under test can be changed, thereby testing the performance of the solenoid valve body under different pressure conditions.

[0031] Working principle: During use, the solenoid valve body is installed on the solenoid valve mounting base 3 with bolts. Test parameters are input through external control equipment, and then the device is started. After the device is started, the servo motor 15 drives the plunger pump 5 to pressurize to the set pressure to transport the fluid. When the fluid passes through the heating mantle 16, it will be heated to the target temperature. After the fluid passes through the solenoid valve body, it flows into the outlet pipe 202. The flow sensor 8 will detect and output the flow data in real time. During this process, the inlet pressure sensor 13 and the outlet pressure sensor 14 will collect the pressure value synchronously and calculate the pressure loss to evaluate the flow resistance characteristics of the solenoid valve body. The tested fluid will flow into the waste liquid collection tank 12 through the outlet pipe 11 for collection.
