Description
Technical Field
[0001] This utility model relates to the technical field of solenoid valve testing equipment, and in particular to a solenoid valve testing device. Background Technology
[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems. In industrial control systems, they are used to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system. The most common types are check valves, safety valves, directional control valves, and speed regulating valves.
[0003] In the production process of solenoid valves, air tightness testing is generally performed to ensure the service life of the solenoid valves. However, existing solenoid air tightness testing devices are difficult to automatically alert users when air leakage occurs. Furthermore, a set of testing devices can only test one type of solenoid valve, which is not very practical. In addition, the solenoid valve is not stable during the air supply test and is prone to shaking, which can easily lead to air leakage at the air supply joint, resulting in inaccurate test results.

[0029] Please refer to Figures 1-3 This utility model provides a solenoid valve detection device, including a support mechanism, a housing, a limiting mechanism, a driving mechanism, a clamping mechanism, a venting mechanism, and an alarm mechanism; wherein,
[0030] The support mechanism includes a support base 1, and a stepped snap-fit groove 2 is provided on the top surface of the support base 1;
[0031] The limiting mechanism is set on the support base 1 inside the box, including the snap-fit seat 3 corresponding to the snap-fit groove 2. The snap-fit seat 3 snaps into the inside of the snap-fit groove 2. The top surface of the snap-fit seat 3 is provided with a limiting groove 4 corresponding to the base of the solenoid valve 23 to be tested. The bottom of the solenoid valve 23 to be tested of the corresponding model can snap into the inside of the limiting groove 4.
[0032] On the top surface of the snap-fit seat 3, on both sides of the limiting groove 4, there are support plates 5 corresponding to the inlet and outlet of the solenoid valve 23 to be tested. On the top surface of the support plate 5, there are U-shaped notches 6 corresponding to the inlet and outlet of the solenoid valve 23 to be tested. That is, the inlet and outlet of the solenoid valve 23 to be tested are supported by the U-shaped notches 6 on the corresponding support plate 5, which further improves the stability of the solenoid valve 23 to be tested placed on the snap-fit seat 3.
[0033] Since the connection between the snap-fit slot 2 and the snap-fit seat 3 is detachable, it enables easy replacement of different snap-fit seats 3, which means it can be adapted to different models and specifications of solenoid valves. It can limit and fix different models and specifications of solenoid valves, thus improving the versatility and practicality of the device.
[0034] The housing is located on the top surface of the support base 1, on the outer side of the snap-fit groove 2, and is used to place the solenoid valve 23 to be tested. The entire housing is designed to be airtight to avoid affecting the test results of the solenoid valve 23.
[0035] In a preferred embodiment, the box body includes four fixed side plates 7 located on the top surface of the support base 1 and circumferentially outside the snap-fit groove 2. The four side plates 7 are arranged in a rectangular shape and are sealed together. A box cover 8 is provided on the top surface of the four side plates 7, and an annular sealing ring is provided on the bottom surface of the box cover 8 corresponding to the top surface of the four side plates 7. The box cover 8 and the four side plates 7 are locked together by a snap-fit lock. The design of the snap-fit lock is similar to the locking method between a food storage container and a food container lid.
[0036] The drive mechanism includes drive components symmetrically arranged on the top surface of the support base 1 on both sides of the housing;
[0037] In a preferred embodiment, the drive assembly includes a support plate 9 fixedly disposed on the top surface of the support base 1, and a horizontal mounting plate 10 fixedly disposed on the top surface of the support plate 9 on the side closer to the housing.
[0038] An upper linear guide rail 11 is fixedly provided on the bottom surface of the mounting plate 10, and a lower linear guide rail 12 is fixedly provided on the top surface of the support base 1 below the upper linear guide rail 11. The upper linear guide rail 11 and the lower linear guide rail 12 are arranged parallel to each other and are arranged in a direction perpendicular to the surface of the adjacent side plate 7.
[0039] A vertical sliding plate 13 is fixedly disposed between the slider 11 of the upper linear guide rail and the slider of the lower linear guide rail 12; a horizontal driving cylinder 14 is disposed between the sliding plate 13 and the supporting plate 9, and the driving cylinder 14 is disposed along the direction of the upper linear guide rail 11; one end of the driving cylinder 14 is fixedly disposed on the inner side plate surface of the supporting plate 9, and the other end is fixedly disposed on the plate surface of the sliding plate 13, for driving the sliding plate 13 to slide.
[0040] The clamping mechanism includes two sets of clamping components disposed inside the housing, which are respectively connected to two sets of drive components through connecting components, and are used to clamp and seal the inlet and outlet of the solenoid valve 23 to be tested;
[0041] In a preferred embodiment, the connecting component includes a connecting rod 15 fixedly disposed on the side of the sliding plate 13 near the housing. The connecting rod 15 is disposed in a sealed sliding manner through the corresponding support plate 9 to prevent air leakage from the housing and thus avoid affecting the detection results of the solenoid valve 23 to be tested.
[0042] In a preferred embodiment, the clamping assembly includes an abutment plate 16 fixedly disposed at one end of the connecting rod 15 located inside the housing. A layer of rubber 17 is fixedly disposed on the side of the abutment plate 16 away from the connecting rod 15. The abutment plate 16 and the rubber 17 in the clamping assembly are used to abut against the inlet and outlet of the solenoid valve 23 to be tested, so as to ensure that the inlet and outlet of the solenoid valve 23 remain sealed and leak-proof.
[0043] A ventilation mechanism, including a ventilation pipe assembly, is mounted on a set of clamping assemblies for performing ventilation detection into the solenoid valve 23 to be tested;
[0044] In a preferred embodiment, the ventilation duct assembly includes an air inlet duct 18 that seals through the surface of any set of abutment plates 16. The air inlet duct 18 is made of a rigid material and is inserted into the inlet of the solenoid valve 23 to be tested for inflating the solenoid valve 23. A ventilation hose 19 is connected to the end of the air inlet duct 18 away from the snap-fit groove 2, and the end of the ventilation hose 19 away from the air inlet duct 18 is sealed and extends out of the corresponding support plate 9. The length of the ventilation hose 19 inside the housing is sufficient to support the travel distance of the abutment plate 16. An air source is connected to the end of the ventilation hose 19 outside the housing.
[0045] The alarm mechanism includes a pressure gauge 20, a buzzer 21, and a controller 22. The pressure gauge 20 and the buzzer 21 are both electrically connected to the controller 22.
[0046] In a preferred embodiment, the detection probe of the pressure gauge 20 is sealed and inserted into the interior of a side plate 7 to monitor the pressure inside the box; the buzzer 21 and the controller 22 are fixedly disposed on the outer surface of the corresponding side plate 7.
[0047] The working principle of this utility model:
[0048] During testing, open the box cover 8, place the snap-fit seat 3 into the snap-fit groove 2, and then place the solenoid valve 23 of the corresponding model and specification into the limiting groove 4 on the snap-fit seat 3. At this time, the inlet and outlet of the solenoid valve 23 are supported on the U-shaped notch 6 on the support plate 5 to ensure the stability of the solenoid valve 23.
[0049] Then, the drive cylinder 14 is activated, which drives the sliding plate 13 to move closer to the housing, and drives the connecting rod 15 and the abutment plate 16 to move closer to the solenoid valve 23 until the air inlet pipe 18 is inserted into the inlet of the solenoid valve 23. The rubber 17 on the abutment plate 16 abuts against the inlet and outlet end faces of the solenoid valve 23. Under the condition of ensuring that the inlet and outlet of the solenoid valve 23 are not leaking, the stability of the solenoid valve 23 is further improved, and the solenoid valve 23 is prevented from shaking during the inflation process, resulting in air leakage at the interface and affecting the test results.
[0050] Cover the box with lid 8 and secure it to the four side panels 7 using snap-lock buckles; then inflate the box and use a pressure gauge 20 to detect the internal air pressure. If the pressure exceeds the set threshold, the signal is transmitted to the controller 22, which then controls the buzzer 21 to sound an alarm, prompting staff to check the box.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.
