Description

Technical Field

[0001] The invention belongs to the field of dynamic response performance detection of electromagnetic components, and in particular relates to a dynamic response performance detection device for an electromagnetic valve and a working method thereof. Background Art

[0002] Solenoid valves, as typical electromagnetic control components, are primarily used to control the flow rate, velocity, and direction of various fluid media. They offer significant advantages such as simple structure, low cost, fast response, and high reliability, playing an indispensable role in aerospace, oil and gas transportation, industrial refrigeration, and other fields. With the advancement of industry, the demand for miniaturized and high-performance solenoid valves in production has become increasingly urgent. The dynamic response performance of a solenoid valve (including response time, electromagnetic force, and magnetic induction intensity) is the most direct indicator of its operating performance and determines its overall performance. To achieve optimal solenoid valve performance, the solenoid valve structure must be optimized. Whether using traditional empirical design methods or the latest electromagnetic simulation optimization design methods, testing the dynamic response performance of the solenoid valve is essential. However, current testing technology for the dynamic response performance of solenoid valves is relatively underdeveloped, resulting in low measurement accuracy and poor sensitivity. The testing equipment is also inefficiently integrated, often requiring multiple sets of equipment to test each performance parameter separately.

[0003] Chinese patent CN 105334477 A proposes a static and dynamic test device for the electromagnetic force of a high-speed solenoid valve. The electromagnetic force measurement module of the device includes a pull-pressure sensor and a force transmission rod. The electromagnetic force generated on the armature under test is sensed by the pull-pressure sensor through the force transmission rod. This method can only detect the electromagnetic force of the solenoid valve. The force transmission rod has poor flexibility, and connecting it to the valve core will affect the measurement results.

[0004] Chinese patent CN 107515063 A proposes a test bench for measuring electromagnetic force in on-off valves. This method uses a micrometer to adjust the air gap and connects a movable iron core to a tension and pressure sensor via a connecting rod to measure electromagnetic force. This method is only applicable to electromagnetic force detection in solenoid valves. Inserting a connecting rod into the valve core increases the load on the movable iron core, thus affecting the measurement results.

[0005] Chinese patent CN 112556910A proposes a locomotive electro-pneumatic valve electromagnetic force measuring device, which also uses a pull-pressure sensor method. It is a single indicator measurement method and does not have the ability to measure the dynamic response performance of the electromagnetic valve in an integrated manner.

[0006] Chinese patent CN 107515063 A proposes a device for testing the delay and response time of solenoid valves. This method calculates the response time by collecting the solenoid valve's pulse width signal and the voltage across a resistor. This method only tests the solenoid valve's response time and requires specific valve processing. This method is difficult to implement and difficult to scale up.

[0007] Chinese patent CN 103399224 A proposes a novel device for detecting the response time of an ABS solenoid valve. However, the device is only applicable to automotive ABS solenoid valves and has low versatility, and cannot meet the detection requirements for the response time of multiple types of solenoid valves.

[0008] Chinese patent CN 103399224 A proposes an automated testing device for solenoid valve response time and leakage level, but it is only applicable to automotive ABS solenoid valves, has low versatility, and cannot meet the response time testing requirements of multiple types of solenoid valves.

[0009] In response to the above problems, this patent aims to propose a device with the technical advantages of high measurement accuracy, high sensitivity, and high equipment integration, which can realize the integrated detection of the magnetic induction intensity, electromagnetic force and response time of the solenoid valve.

[0025] A working method of a solenoid valve dynamic response performance detection device includes the following steps:

[0026] A. Install the solenoid valve

[0027] Install the solenoid valve on the solenoid valve fixture so that the axial direction of the solenoid valve is perpendicular to the upper end surface of the movable part;

[0028] B. Measuring magnetic field strength

[0029] B1. Adjust the steering adjustment mechanism so that the movable part is fixed in the Y-shaped opening of the clamping block with the large end facing upwards and tighten the fastening nut. At this time, the axial direction of the solenoid valve is parallel to the Z axis.

[0030] B2.

[0031] C. Detection of electromagnetic force

[0032] C1. Adjust the steering mechanism so that the movable part contacts the left inclined surface of the trapezoidal platform of the clamping block, with the large end facing left, and tighten the fastening nut. At this point, the axial direction of the solenoid valve is parallel to the X-axis.

[0033] C2. Connect the unconnected end of the high-performance fiber cable to the moving iron core of the solenoid valve. Power on the solenoid valve, turn on the digital dynamometer, and use the X-axis moving platform to move the digital dynamometer away from the solenoid valve until the moving iron core is out of the solenoid valve.

[0039] The working principle of the present invention is as follows:

[0040] The present invention's magnetic field strength measurement module uses the Hall effect principle for detection. A Hall effect sensor generates current and voltage when magnetic lines of force pass through an object, which are converted into magnetic induction intensity by a gaussmeter. The gaussmeter probe can achieve micron-level precision by controlling the combined motion of the platform's X, Y, and Z axes using host computer software to reach the detection position.

[0041] 2. The electromagnetic force measurement module of the present invention uses a resistive strain gauge to measure electromagnetic force, offering the advantages of high resolution and minimal error. During testing, a digital force gauge using a resistive strain gauge requires a high-performance fiber cable to connect the digital force gauge probe to the solenoid valve's moving iron core. Adjusting the adjustable foot cup and the platform's Y-axis aligns the digital force gauge probe and the solenoid valve's moving iron core.

[0042] 3. The response time measurement module of the present invention utilizes optical sensing principles for detection, offering the advantages of high sampling frequency and a wide measurement range. A laser coaxial displacement sensor is aligned with the position of the moving iron core, detecting the relationship between time and displacement during the moving iron core's engagement process to achieve response time measurement. During measurement, the laser coaxial displacement sensor and the solenoid valve's moving iron core can be aligned by adjusting the Z-axis motion stage and the platform's Y-axis.

[0043] Compared with the prior art, the present invention has the following beneficial results:

[0044] 1. In the measurement of response time, the present invention uses a high-sampling-frequency, high-sensitivity laser coaxial displacement meter, which has extremely high detection accuracy and can complete the test of three parameters: magnetic induction intensity, electromagnetic force, and response time with only one clamping. It has higher efficiency and provides a new method for the optimization design of solenoid valves and the verification of solenoid valve simulation models.

[0045] 2. This invention proposes an integrated detection device for electromagnetic valve magnetic induction intensity, electromagnetic force, and response time, featuring high measurement accuracy, high sensitivity, and a high degree of device integration. The device can complete the detection of three parameters of the solenoid valve, namely magnetic induction intensity, electromagnetic force, and response time, in a single clamping operation, improving detection accuracy and shortening detection time.
