[0002] Solenoid valves are basic automation components used to control fluids in hydraulic and pneumatic control systems and are widely used in various precision instruments. When the solenoid valve is working, the movement of the valve core is controlled to open and close the solenoid valve, thereby realizing the flow of fluids in and out. Among them, the air tightness of the solenoid valve is an important factor affecting the performance of the instrument. The existing solenoid valve air tightness detection method is to fix the valve body of the solenoid valve on the valve block with screws for ventilation detection. Only one can be detected at a time, and the detection efficiency is low. It cannot meet the detection needs of large quantities of solenoid valves. At the same time, during the disassembly and assembly process, the valve body is easily damaged, which increases the unqualified rate of the solenoid valve and thus increases the cost.

[0004] Although the above-mentioned disclosed device can detect multiple solenoid valves at the same time, the solenoid valves need to be installed before detection. After a batch of solenoid valves are detected, the detected solenoid valves need to be removed, and then the solenoid valves to be detected need to be installed for the next detection. The solenoid valves cannot be detected continuously, and the working efficiency is still low.

[0005] Therefore, a solenoid valve air tightness testing device is needed to solve the above problems. Summary of the invention

The gas enters the solenoid valve through the inflation hole. After the pressure in the solenoid valve reaches the working pressure during use, the side pump stops running, and the electric telescopic rod drives the solenoid valve to rise. When the first button is pressed, the middle pump stops running, and the middle position of the inner sliding cavity is connected to the outside.

When a leaking solenoid valve is detected, the clamping plate is loosened at the top, the solenoid valve falls onto the first rubber plate and slides down from the first sliding plate, and the solenoid valve that does not leak falls onto the second rubber plate and falls down from the second sliding plate, so that the solenoid valves that meet the standards and those that do not meet the standards are automatically classified, thereby improving work efficiency.

By arranging two first beveled tooth grooves with opposite beveled tooth surfaces and arranging a first beveled tooth block driven by a pull rod, when it is necessary to slide the inner slide rod, the pull rod is pulled to disengage the first beveled tooth block from the first beveled tooth groove. When it is necessary to lock the inner slide rod with the outer sleeve, the pull rod is released to push the first beveled tooth block so that the first beveled tooth block abuts against the first beveled tooth groove, which is easy to operate.

[0019] 3. The present invention sets two buttons. When the second button is pressed by the extension block, the middle pump draws air outward, so that the two clamping plates clamp the solenoid valve, and the side pump inflates the inner sliding cavity. The gas enters the solenoid valve through the inflation hole. After the pressure in the solenoid valve reaches the working pressure during use, the side pump stops running, and the electric telescopic rod drives the solenoid valve to rise. When the first button is pressed, the middle pump stops running, and the middle position of the inner sliding cavity is connected to the outside. At this time, if the solenoid valve leaks, the inner slide plate will slide outward to loosen the solenoid valve and make it fall. If the solenoid valve is sealed to the standard and there is no leakage, the inner slide plate will not slide, the clamping plate continues to clamp the solenoid valve, and then the telescopic end of the electric telescopic rod drops. This setting can automatically separate the leaking solenoid valve and reduce the workload in the later stage.

[0020] 4. The present invention makes the two ends of the two rubber plates not fixed to the side plates. When the electric telescopic rod drives the solenoid valve to rise, the two rubber plates will be pushed and bent, thereby not affecting the rise of the solenoid valve. When a leaking solenoid valve is detected, the clamping plate is loosened at the top, and the solenoid valve falls onto the first rubber plate and slides off the first sliding plate. The solenoid valve that is not leaking falls onto the second rubber plate and falls off the second sliding plate. The solenoid valves that meet the standards and those that do not meet the standards are automatically classified to improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
