Description

Technical Field

[0001] This utility model relates to the field of testing devices, and in particular to a testing device for a multi-port automatic pressurization electromagnetic pilot valve. Background Technology

[0002] Electromagnetic pilot valves are widely used in the field of industrial automation control. They are mainly used to control the flow of gas or liquid and are often used as control elements in control systems. After the pilot valve is manufactured, it usually needs to be tested and inspected before leaving the factory to ensure that it functions properly.

[0003] The fixing mechanism of the pilot valve testing device used in the prior art usually consists of a set of hydraulic drive components and a set of clamping components. During the test, the pilot valve needs to be fixed in the clamping components first. The hydraulic drive components are then used to drive the clamping components to fix the pilot valve before testing can be performed. After the test is completed, the pilot valve needs to be removed. During the removal and installation of the pilot valve, the testing device body will be in standby mode, resulting in low overall testing efficiency. To address these issues, a multi-port automatic pressurization electromagnetic pilot valve testing device is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-port automatic pressurization electromagnetic pilot valve testing device, which aims to improve the problem that "the fixed mechanism of the pilot valve testing device used in the prior art only has a single station, resulting in low testing efficiency during use".

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a multi-port automatic pressurization electromagnetic pilot valve test device, comprising a base plate, a support frame fixedly connected to the upper surface of the base plate, a drive assembly provided at the right end of the support frame, a lifting frame slidably connected to the inner wall of the support frame, the drive assembly including a hydraulic rod, the hydraulic rod being mounted on the upper surface of the base plate, a slide plate fixedly connected to the left end of the hydraulic rod output shaft, the slide plate and the lifting frame being interconnected by a hinge plate, multiple sets of lifting frames and hinge plates being arranged in a rotating array around the center line of the slide plate as the rotation axis, a fixing mechanism provided on the outer wall of the lifting frame, the fixing mechanism including a slider, the slider sliding on the upper surface of the lifting frame, a pressing plate fixedly connected to the upper surface of the slider, a limit rod fixedly connected to the upper surface of the base plate, a connecting pipe fixedly connected to the pressing plate through a connecting sleeve, and a valve body placed on the upper surface of the lifting frame.

[0006] As a further description of the above technical solution:

[0009] A return spring is fixedly connected to the right end of the slider, and a support plate is fixedly connected to the right end of the return spring. The support plate is fixedly connected to the inner wall of the lifting frame.

[0010] As a further description of the above technical solution:

[0011] A three-way pipe is fixedly connected to the left end of the connecting pipe, and a solenoid valve is installed on the inner wall of the three-way pipe.

[0012] As a further description of the above technical solution:

[0014] As a further description of the above technical solution:

[0015] The slider, extrusion plate, and return spring are provided in multiple sets, and the multiple sets of slider, extrusion plate, and return spring are symmetrically arranged with the center line of the support plate as the axis of symmetry.

[0019] The lower end of the hinge plate is hinged to the upper end of the slide plate, and the upper end of the hinge plate is hinged to the lower surface of the lifting frame.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by using a set of driving devices to drive two sets of lifting frames to move up and down alternately, when one set of valve bodies is being tested, another set of valve bodies to be tested can be installed on the surface of the other set of lifting frames that are in a lower position. When the valve body being tested is completed, the other set of valve bodies that have not been tested can be directly sent into the testing position. Thus, there is no need to wait for installation and disassembly, and the overall testing efficiency of the device is high.

[0022] 2. In this utility model, by setting a fixing mechanism, when the lifting frame moves upward, the extrusion plate will automatically move inward under the extrusion of the limiting rod. The inward movement of the extrusion plate will drive the connecting sleeve to move inward, so that the connecting pipe can be brought into contact with the valve body, and then the testing can begin. When the lifting frame moves downward, the reset spring will push the slider to drive the extrusion plate to move outward and reset. The whole device is convenient to fix and disassemble.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 - Figure 3This utility model provides an embodiment of a multi-port automatic pressurization electromagnetic pilot valve testing device, comprising a base plate 1 for supporting the overall device, a support frame 2 for supporting the movement of a lifting frame 4 fixedly connected to the upper surface of the base plate 1, a drive assembly 3 for driving the movement of the lifting frame 4 provided at the right end of the support frame 2, and a lifting frame 4 for driving the valve body 5 to move up and down slidably connected to the inner wall of the support frame 2, the drive assembly 3 including a hydraulic rod 31 for providing power to the overall device, the hydraulic rod 31 being mounted on the upper surface of the base plate 1, and a slide plate 32 for driving the movement of a hinge plate 33 fixedly connected to the left end of the output shaft of the hydraulic rod 31, the slide plate 32 and the lifting frame 4 being interconnected through the hinge plate 33, the slide plate 32 pushing the hinge plate when it moves to the left. 33 drives the lifting frame 4 to move upward. The lifting frame 4 and the hinge plate 33 are provided in multiple sets. The multiple sets of lifting frames 4 and hinge plates 33 are arranged in a rotating array with the center line of the slide plate 32 as the rotation axis. The outer wall of the lifting frame 4 is provided with a fixing mechanism 6 for fixing the valve body 5. The fixing mechanism 6 includes a slider 64 for supporting the movement of the extrusion plate 63. The slider 64 slides on the upper surface of the lifting frame 4. The slider 64 can slide left and right on the upper surface of the lifting frame 4. The extrusion plate 63 for driving the connecting sleeve 65 is fixedly connected to the upper surface of the slider 64. The upper surface of the base plate 1 is fixedly connected with a limiting rod 66 for extruding the extrusion plate 63. The extrusion plate 63 is fixedly connected to a connecting pipe 7 for connecting the test device through the connecting sleeve 65. The valve body 5 is placed on the upper surface of the lifting frame 4.

[0030] Reference Figure 1 - Figure 3 The connecting sleeve 65 is fixedly connected to the rear surface of the extrusion plate 63. When the extrusion plate 63 moves left and right, the connecting sleeve 65 will be driven to move left and right synchronously. The connecting pipe 7 is fixedly connected to the inner wall of the connecting sleeve 65. When the connecting sleeve 65 moves to the right, it can drive the connecting pipe 7 to dock with the valve body 5. The connecting pipe 7 is a flexible hose that can be bent. The right end of the slider 64 is fixedly connected to a reset spring 62 for driving the slider 64 to reset. The right end of the reset spring 62 is fixedly connected to a support plate 61 for supporting the reset spring 62. The support plate 61 is fixedly connected to the inner wall of the lifting frame 4. The reset spring 62 will push the slider 64 outward at all times under the support of the support plate 61. The left end of the connecting pipe 7 is fixedly connected to a three-way pipe 9 for connecting the connecting pipe 7 and the test device. The inner wall of the three-way pipe 9 is equipped with a solenoid valve 8 for controlling the internal communication direction of the three-way pipe 9.

[0031] Reference Figure 1 - Figure 3The upper surface of the lifting frame 4 is set as a semi-circular arc. The arc design can better fit the outer wall of the valve body 5. There are multiple sets of sliders 64, extrusion plates 63, and return springs 62. The multiple sets of sliders 64, extrusion plates 63, and return springs 62 are symmetrically arranged with the center line of the support plate 61 as the axis of symmetry. The two sets of symmetrically arranged extrusion plates 63 can drive the connecting pipes 7 on both sides to connect to the valve body 5 at the same time. The left end of the extrusion plate 63 is set as an inclination. When the extrusion plate 63 is squeezed by the limit rod 66, the extrusion plate 63 will be forced to move inward. The lower end of the hinge plate 33 is hinged to the upper end of the slide plate 32, and the upper end of the hinge plate 33 is hinged to the lower surface of the lifting frame 4. When the slide plate 32 moves to the left, it will push the hinge plate 33 to drive the lifting frame 4 to move upward.

[0032] Working principle: The electromagnetic pilot valve body 5 to be tested is placed on the upper surface of the lowered lifting frame 4. At this time, the return spring 62 is in a naturally extended state. Under its action, the slider 64 drives the extrusion plate 63 to move outward to the initial position, and the connecting pipe 7 moves away from the valve body 5. The hydraulic rod 31 is activated, and the output shaft of the hydraulic rod 31 pushes the slide plate 32 to move to the left. When the slide plate 32 moves, it drives the lifting frame 4 to move upward through the hinge plate 33. Since multiple sets of lifting frames 4 and hinge plates 33 are arranged in a rotating array around the center line of the slide plate 32, when one set of lifting frames 4 moves upward, another set of lifting frames 4 moves downward, which facilitates the alternating placement and testing of the valve body 5. As the lifting frame 4 moves upward, the extrusion plate 63 moves away from the valve body 5. The pressure plate 63 will gradually approach the limit rod 66. When the pressure plate 63 contacts the limit rod 66, since the left end of the pressure plate 63 is inclined, under the pressure of the limit rod 66, the pressure plate 63 overcomes the elastic force of the return spring 62 and drives the slider 64 to slide inward. While the pressure plate 63 moves inward, it drives the connecting pipe 7 to approach the valve body 5 through the connecting sleeve 65 until the interface between the connecting pipe 7 and the valve body 5 is tightly fitted. After the connecting pipe 7 and the valve body 5 are connected, the solenoid valve 8 on the inner wall of the three-way pipe 9 is opened. The test device applies pressure to the valve body 5 through the three-way pipe 9 and the connecting pipe 7 to perform performance testing of the solenoid pilot valve, such as testing its opening and closing status and sealing performance under different pressures.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
